Description

Satellitennavigationssystem-Datenempfänger und damit durchzuführendes Verfahren zum Dokumentieren des Zustande einer in oder an einem Gebäude installierten technischen Vorrichtung  Satellite navigation system data receiver and method to be performed therefor for documenting the state of a technical device installed in or on a building
Die Erfindung betrifft einen Satellitennavigationssystem-Datenempfänger mit (a) einem Empfangsmodul, das ausgebildet ist zum automatischen Empfangen von Satelliten-Funksignalen und zum Ermitteln einer absoluten Position aus den Satelliten-Funksignalen, und (b) einem digitalen Speicher. Gemäß einem zweiten Aspekt betrifft die Erfindung ein Verfahren zum Dokumentieren eines Zustands und/oder von Umgebungsparametern einer in oder an einem Gebäude installierten Vorrichtung. The invention relates to a satellite navigation system data receiver having (a) a receiving module adapted to automatically receive satellite radio signals and to determine an absolute position from the satellite radio signals, and (b) a digital memory. According to a second aspect, the invention relates to a method for documenting a state and / or environmental parameters of a device installed in or on a building.
Um eine technische Vorrichtung, beispielsweise eine Brandschutzvorrichtung, abzunehmen, muss der verantwortliche Anlagenbauer vor Ort erscheinen und den Zustand der Vorrichtung dokumentieren. Die Dokumentation dient dazu, die korrekte Errichtung und Funktion der Vorrichtung zu bestätigen, so dass etwaige spätere Fehlfunktionen entweder einer fehlerhaften Errichtung oder aber einem fehlerhaften Betrieb zugeordnet werden können. Die Abnahme der Vorrichtung stellt einen integralen Bestandteil der Herstellung der Vorrichtung dar, da für den späteren Betreiber ein Betreiben der Vorrichtung ohne Abnahme aus rechtlichen oder gesetzlichen Gründen oft nicht möglich oder inakzeptabel ist. In order to remove a technical device, for example a fire protection device, the responsible plant engineer must appear on site and document the state of the device. The documentation serves to confirm the correct establishment and function of the device, so that any subsequent malfunctions can be assigned to either a faulty installation or a faulty operation. The removal of the device is an integral part of the manufacture of the device, as operating the device without acceptance for legal or legal reasons is often not possible or unacceptable for the later operator.
BESTÄTIGUNGSKOPIE Wegen der hohen Bedeutung der Abnahme wird sie in der Regel gemeinsam vom Hersteller und dem Betreiber durchgeführt. Beide Seiten müssen dabei sicherstellen, dass die Dokumentation des Zustands der Vorrichtung nicht unberechtigt zu Ungunsten eines der Beteiligten ausfällt. CONFIRMATION COPY Due to the high importance of the decrease, it is usually carried out jointly by the manufacturer and the operator. Both sides must ensure that the documentation of the condition of the device does not turn out to be unjustified to the disadvantage of one of the involved parties.
Die Abnahme ist für den Hersteller dann besonders aufwändig, wenn die abzunehmende Vorrichtung sicherheitsrelevant und entfernt von dem Sitz des Herstellers der Vorrichtung ist. Beispielsweise wird im Rahmen des Verfahrens der Zustand einer Brandschutzvorrichtung dokumentiert, die zu einem großen Teil vorgefertigt geliefert werden kann, bei der aber der korrekte Einbau besonders wichtig ist, da sicherheitsrelevant. Die Abnahme hat in diesem Fall einen signifikanten Anteil am Gesamtaufwand für die Herstellung der Brandschutzvorrichtung. The decrease is particularly costly for the manufacturer if the device to be removed is safety-relevant and remote from the seat of the manufacturer of the device. For example, the condition of a fire protection device is documented as part of the process, which can be delivered prefabricated to a large extent, but in which the correct installation is particularly important because safety relevant. The decrease in this case has a significant share of the total cost of making the fire protection device.
Die Abnahme einer technischen Vorrichtung beinhaltet vor allem die technische Dokumentation ihres Zustands, was durch Aufnehmen von technischen Messdaten erfolgt. Es muss dabei sichergestellt sein, dass die aufgenommenen Messdaten tatsächlich von der abzunehmenden Vorrichtung stammen. Insbesondere muss sichergestellt sein, dass nicht Messdaten einer anderen Vorrichtung aufgenommen und für die Messdaten der abzunehmenden Vorrichtung ausgegeben werden. So ist es möglich, mit einem bekannten Satellitennavigationssystem-Datenempfänger die absolute Position der abzunehmenden technischen Vorrichtung zu ermitteln. Es kann jedoch zu Fehlern beim Übertragen der Positionsdaten kommen, die entweder auf einer fehlerhaften Durchführung des Verfahrens beruhen oder absichtlich eingebracht werden. The acceptance of a technical device includes above all the technical documentation of its condition, which takes place by recording technical measurement data. It must be ensured that the recorded measurement data actually come from the device to be removed. In particular, it must be ensured that measurement data of another device are not recorded and output for the measurement data of the device to be removed. Thus, it is possible to determine the absolute position of the technical device to be accepted with a known satellite navigation system data receiver. However, there may be errors in transmitting the position data, which are either due to a faulty implementation of the method or deliberately introduced.
Aus der DE 197 01 039 C1 ist ein Verfahren zur Sicherung von Positionsdaten für ein Fahrzeug bekannt. Bei dem beschriebenen Verfahren wird die Position beispielsweise eines Autos ermittelt und so verschlüsselt übertragen, dass nur der berechtigte Besitzer die Position des Fahrzeugs ermitteln kann. Dass Aufnehmen von Daten, die nicht Positionsdaten sind, ist nicht vorgesehen. From DE 197 01 039 C1 a method for securing position data for a vehicle is known. In the described method, the position of, for example, a car is determined and transmitted in an encrypted manner so that only the authorized owner can determine the position of the vehicle. That capturing data that is not positional data is not scheduled.
In der US 2007/0 182 544 A1 ist ein Verfahren beschrieben, mittels dem ein Objekt, wie beispielsweise ein Container, dauerhaft hinsichtlich seiner Position als auch hinsichtlich seiner Umgebungseigenschaften überwacht werden kann. Ein Verfahren, das es ermöglichen würde, die Abnahme einer technischen Vorrichtung aus der Ferne durchzuführen, wird nicht beschrieben. US 2007/0 182 544 A1 describes a method by means of which an object, such as a container, can be permanently monitored with respect to its position as well as its environmental properties. A method which would make it possible to remotely perform the removal of a technical device will not be described.

The object of the invention is to simplify the acceptance and documentation of technical devices, in particular of fire protection devices, and to avoid errors.

Gemäß einem zweiten Aspekt löst die Erfindung das Problem durch ein Verfahren zum Dokumentierten der technischen Eigenschaft einer in oder an einem Gebäude installierten technischen Vorrichtung, mit den Schritten (i) Erfassen einer Auftragsnummer, die zumindest auch einen Auftrag zum Dokumentieren des technischen Zustandes der Vorrichtung kennzeichnet, und einer Seriennummer eines erfindungsgemäßen Satellitennavigationssystem-Datenempfängers, wobei die Auftragsnummer insbesondere von einem Auftragserteilungsrechner empfangen wird, (ii) Erzeugen eines externen digitalen Schlüssels und Erstellen einer Verknüpfung zwischen der Auftragsnummer und dem externen digitalen Schlüssel, beispielsweise durch Eintragen in eine Datenbank, (iii) Senden der Auftragsnummer, insbesondere an einen Auftragserteilungsrechner, (iv) Empfangen von verschlüsselten Positions-Signalen des Satellitennavigationssystem-Datenempfängers, die anhand eines Empfänger-Schlüssels verschlüsselt wurden, der im Satellitennavigationssystem-Datenempfänger gespeichert ist, und der Auftragsnummer oder von Daten, anhand derer die Auftragsnummer ermittelbar ist, (v) Ermitteln des Empfänger-Schlüssels aus der Seriennummer des Satellitennavigationssystem-Datenempfängers, beispielsweise durch Abfragen einer Datenbank, (vi) Ermitteln, ob das verschlüsselte Positions-Signal anhand des Empfänger-Schlüssels dekodierbar ist, (vii) verneinendenfalls Ausgeben einer Warnmeldung und bejahendenfalls Senden eines externen digitalen Schlüssels an eine erfindungsgemäße Dokumentiervorrichtung mittels einer gesicherten Verbin- dung, und (viii) Empfangen von mit dem externen digitalen Schlüssel verschlüsselten Dokumentationsdaten und Entschlüsseln der Dokumentationsdaten mit dem externen digitalen Schlüssel oder Bereitstellen der verschlüsselten Dokumentationsdaten, insbesondere Senden der verschlüsselten Dokumentationsdaten an den Auftragerteilungsrechner, so dass die technische Eigenschaft der Vorrichtung dokumentiert ist. According to a second aspect, the invention solves the problem by a method for documenting the technical property of a technical device installed in or on a building, comprising the steps of (i) detecting an order number which also identifies at least one order for documenting the technical condition of the device , and a serial number of a satellite navigation system data receiver according to the invention, the order number being received, in particular, by an order issuing computer, (ii) generating an external digital key and establishing a link between the order number and the external digital key, for example by entry in a database (iii Sending the job number, in particular to an order-issuing computer, (iv) receiving encrypted position signals of the satellite navigation system data receiver that have been encrypted using a receiver key that i m satellite navigation system data receiver is stored, and the order number or data from which the order number is determined, (v) determining the receiver key from the serial number of the navigation satellite data receiver, for example by querying a database, (vi) determining whether the encrypted position signal is decodable on the basis of the receiver key, (vii) if not, issuing a warning message and, if so, sending an external digital key to a documenting device according to the invention by means of a secure connection and (viii) receiving documentation data encrypted with the external digital key and decrypting the documentation data with the external digital key or providing the encrypted documentation data, in particular sending the encrypted documentation data to the job issuing computer so that the technical property of the device is documented.
Vorteilhaft an der Erfindung ist, dass durch die Verwendung des erfindungsgemäßen Satellitennavigationssystem-Datenempfängers die absoluten Koordinaten des Satellitennavigationssystem-Datenempfängers stets sicher bekannt sind, ohne dass bewusste oder unbewusste Fehler auftreten können. Die Wahrscheinlichkeit von Fehlern bei der Abnahme von technischen Vorrichtungen wird damit deutlich reduziert. An advantage of the invention is that by using the satellite navigation system data receiver according to the invention, the absolute coordinates of the satellite navigation system data receiver are always safely known without conscious or unconscious errors can occur. The probability of errors in the removal of technical devices is thus significantly reduced.
Im Rahmen der vorliegenden Beschreibung wird unter einem Satellitennavigationssystem-Datenempfänger eine Vorrichtung verstanden, die ausgebildet ist zum Empfangen von Funksignalen von Satelliten und zum Errechnen der absoluten Position relativ zum Erdkoordinatensystem aus diesen Funksignalen. In the context of the present description, a satellite navigation system data receiver is understood to mean a device which is designed to receive radio signals from satellites and to calculate the absolute position relative to the earth coordinate system from these radio signals.
Unter dem Merkmal, dass das Empfangsmodul ausgebildet ist zum Ermitteln einer absoluten Position wird insbesondere verstanden, dass das Empfangsmodul so ausgebildet ist, dass die absoluten Koordinaten der Position des Satellitennavigationssystem-Datenempfängers auf eineindeutige Weise berechnet werden können. So ist es möglich, nicht aber notwendig, dass die absolute Position direkt kodiert wird. Es ist auch möglich, dass eine Position relativ zu einer Referenzposition angegeben wird, so dass aus der absoluten Position der Referenzposition und der vom Empfangsmodul abgegebenen relativen Position zu dieser Referenzposition die absolute Position ein-eindeutig ermittelbar ist. In particular, the feature that the receiving module is designed to determine an absolute position means that the receiving module is designed in such a way that the absolute coordinates of the position of the satellite navigation system data receiver can be calculated in an unambiguous manner. So it is possible, but not necessary, that the absolute position is coded directly. It is also possible for a position to be specified relative to a reference position, so that the absolute position can be unambiguously determined from the absolute position of the reference position and the relative position output by the receiving module relative to this reference position.
Unter dem verschlüsselten Positionssignal wird insbesondere eine Folge von Zeichen, beispielsweise eine binäre Folge oder eine alphanumerische Folge von Zeichen oder Ziffern, verstanden, die nur anhand des Empfänger-Schlüssels in eine verständliche Kodierung der absoluten Position überführt werden kann. Under the encrypted position signal is in particular a consequence of characters, for example a binary sequence or an alphanumeric sequence of characters or numbers, understood that can be converted only by the receiver key in an intelligible coding of the absolute position.
Unter Umgebungsparametern werden insbesondere physikalische Größen verstanden, die beispielsweise die Eigenschaften der Atmosphäre oder physikalischer Felder charakterisieren. Umgebungsparameter können beispielsweise der Luftdruck, die absolute Luftfeuchtigkeit, die Temperatur, die Windgeschwindigkeit oder der Schallpegel sein. Under environmental parameters are understood in particular physical quantities that characterize, for example, the properties of the atmosphere or physical fields. Environmental parameters may be, for example, air pressure, absolute humidity, temperature, wind speed or sound level.
In Schritt (i) wird die Auftragsnummer vorzugsweise von dem örtlich um beispielsweise mehr als 10 Kilometer beabstandeten Auftragserteilungsrechner empfangen. In step (i), the order number is preferably received from the order placement computer spatially spaced more than 10 kilometers, for example.
Vorzugsweise besitzt der Satellitennavigationssystem-Datenempfänger eine Rechner-Schnittstelle, die ausgebildet ist zum Kommunizieren mit einem Rechner. Beispielsweise handelt es sich bei der Rechner- Schnittstelle um eine USB-Schnittstelle oder eine Bluetooth-Schnittstelle. Preferably, the satellite navigation system data receiver has a computer interface adapted to communicate with a computer. For example, the computer interface is a USB interface or a Bluetooth interface.
Gemäß einer bevorzugten Ausführungsform ist der digitale Empfänger- Schlüssel unveränderbar und/oder unauslesbar im digitalen Speicher gespeichert. Das stellt sicher, dass der digitale Empfänger-Schlüssel nur demjenigen bekannt ist, der ihn im digitalen Speicher abgespeichert hat. Insbesondere ist der Empfänger-Schlüssel nicht von einem unbefugten Dritten ermittelbar, der den Satellitennavigationssystem-Datenempfänger zur Verfügung hat. According to a preferred embodiment, the digital receiver key is stored immutable and / or inexplicable in the digital memory. This ensures that the digital receiver key is known only to the person who has stored it in the digital memory. In particular, the recipient key is not identifiable by an unauthorized third party having the satellite navigation system data receiver.
Unter dem Merkmal, dass der digitale Empfänger-Schlüssel unveränderbar gespeichert ist, wird insbesondere verstanden, dass eine gezielte Änderung des Empfänger-Schlüssels physikalisch ausgeschlossen oder so gesichert ist, dass ein Dritter, der nicht über das Wissen des Herstellers verfügt, den Empfänger-Schlüssel nicht ändern kann. Beispielsweise ist der Empfänger-Schlüssel in einem Nur-Lese-Speicher abgelegt, der nur nicht elektrisch geändert werden kann. Beispielsweise ist dieser Nur-Lese- Speicher nur mit UV-Licht beschreibbar und auf für UV-Licht undurchlässige Weise vergossen. By the feature that the digital receiver key is stored immutable, it is understood, in particular, that a targeted change of the receiver key is physically excluded or so secured that a third party that does not have the knowledge of the manufacturer does not change the recipient key. For example, the receiver key is stored in a read-only memory, which only can not be electrically changed. For example, this read-only memory is writable only with UV light and sealed in UV-opaque way.
Unter dem Merkmal, dass der Empfänger-Schlüssel unauslesbar im digitalen Speicher gespeichert ist, wird insbesondere verstanden, dass es zwar theoretisch möglich ist, den digitalen Speicher gezielt so zu zerstören, dass der Empfänger-Schlüssel beispielsweise mittels Rastersondenmikroskopie auslesbar ist, dass aber ein zerstörungsfreies Auslesen nicht möglich ist. Under the feature that the receiver key is stored inexplicably stored in the digital memory, is understood in particular that although it is theoretically possible to deliberately destroy the digital memory so that the receiver key, for example by means of scanning probe microscopy is readable, but that a non-destructive Reading is not possible.
Bevorzugt kennzeichnet der Empfänger-Schlüssel den Satellitennavigationssystem-Datenempfänger ein-eindeutig. Erfindungsgemäß ist nämlich auch ein Satz aus mindestens zwei erfindungsgemäßen Satellitennavigationssystem-Datenempfängern, wobei jeder der Satellitennavigationssystem-Datenempfänger in diesem Satz einen individuellen und einzigartigen Empfänger-Schlüssel gespeichert enthält. Das hat den Vorteil, dass festgestellt werden kann, ob Positionsdaten mit einem vorgegebenen Satellitennavigationssystem-Datenempfänger aufgenommen wurden. Gelingt nämlich das Dekodieren mit dem zugehörigen Empfänger-Schlüssel, so beweist dies, dass der entsprechende Satellitennavigationssystem- Datenempfänger verwendet wurde. Gelingt es nicht, muss ein anderer Satellitennavigationssystem-Datenempfänger verwendet worden sein. Preferably, the receiver key uniquely identifies the satellite navigation system data receiver. In fact, according to the present invention, there is also a set of at least two satellite navigation system data receivers according to the invention, wherein each of the navigation satellite data receivers in this set contains an individual and unique receiver key. This has the advantage that it can be determined if position data has been recorded with a given satellite navigation system data receiver. If the decoding succeeds with the associated receiver key, this proves that the corresponding satellite navigation system data receiver has been used. If it fails, another satellite navigation system data receiver must have been used.
Bevorzugt hat der Satellitennavigationssystem-Datenempfänger eine auslesbare Seriennummer, die den Satellitennavigationssystem- Datenempfänger eindeutig kennzeichnet. Diese auslesbare Seriennummer kann beispielsweise elektrisch auslesbar in dem digitalen Speicher gespeichert sein. Denkbar ist aber auch, dass die Seriennummer vom Menschen wahrnehmbar beispielsweise auf einem Gehäuse angebracht ist oder dass die Seriennummer durch einen Barkode kodiert am Satellitennavigationssystem-Datenempfänger angegeben ist. Eine derartig auslesbare Seriennummer hat den Vorteil, dass der Satellitennavigationssystem-Datenempfänger anhand dieser Seriennummer identifizierbar ist, so dass der Empfänger-Schlüssel für denjenigen ermittelbar ist, der beide Daten miteinander verknüpft kennt. Preferably, the satellite navigation system data receiver has a readable serial number uniquely identifying the satellite navigation system data receiver. This readable serial number can, for example, be stored in the digital memory in an electrically readable manner. It is also conceivable that the serial number perceptible by humans, for example, mounted on a housing or that the serial number is encoded by a bar code encoded at the satellite navigation system data receiver. Such a readable serial number has the advantage that the navigation satellite system data receiver is identifiable from this serial number, so that the receiver key can be determined for the one who knows the two data linked together.
Vorzugsweise besitzt der Satellitennavigationssystem-Datenempfänger einen Sender, dessen Reichweite unter Standardbedingungen höchstens 1000 m beträgt. Hierbei handelt es sich beispielsweise um einen Bluetooth-Sender, der auf einer Frequenz sendet, bei dem die Absorption durch die umgebende Luft im Vergleich zu seiner Sendestärke so groß ist, dass das Signal sich außerhalb eines Umkreises von 1000 m nur mit so hohem technischen Aufwand empfangen lässt, dass es eine technische Spezialausrüstung erfordert. Das macht es möglich, den Satellitennavigationssystem-Datenempfänger beabstandet von der zu dokumentierenden technischen Vorrichtung anzuordnen und dennoch sicherzugehen, dass der Abstand von der kodiert übertragenen absoluten Position höchstens 1000 m beträgt. Preferably, the satellite navigation system data receiver has a transmitter whose range under standard conditions is at most 1000 m. This is, for example, a Bluetooth transmitter that transmits at a frequency at which the absorption by the surrounding air is so great compared to its transmission strength that the signal can only be located outside a radius of 1000 m with such high technical complexity that it requires specialized technical equipment. This makes it possible to arrange the satellite navigation system data receiver at a distance from the technical device to be documented and yet to ensure that the distance from the coded transmitted absolute position is at most 1000 m.
Gemäß einer bevorzugten Ausführungsform ist das Empfangsmodul ausgebildet zum automatischen Abgeben eines Schlüssel-Positionssignals, das zusätzlich zur absoluten Position des Satellitennavigationssystem- Datenempfängers auch Satelliten-Kennungen derjenigen Satelliten, deren Signale empfangbar sind, und/oder Signalstärken derjenigen Satelliten, deren Signale empfangbar sind, kodiert. Hierunter sind die Kennungen bzw. Signalstärken derjenigen Satelliten zu verstehen, die zu dem Moment gemessen werden, zu dem auch die absolute Position bestimmt wird. According to a preferred embodiment, the receiving module is designed to automatically output a key position signal which in addition to the absolute position of the satellite navigation system data receiver also satellite identifiers of those satellites whose signals are receivable, and / or signal strengths of those satellites whose signals are receivable encoded , These are the identifiers or signal strengths of those satellites that are measured at the moment when the absolute position is determined.
Anhand dieser Daten lässt sich ein zusätzlicher Plausibilitätstest erstellen, anhand dessen die ermittelte Position verifizierbar ist. Erfindungsgemäß ist zudem eine Dokumentiervorrichtung, die neben einem erfindungsgemäßen Satellitennavigationssystem-Datenempfänger einen Prozessor, der eine Speichereinheit umfasst, und eine Aufzeichnungsvorrichtung aufweist, mittels der Dokumentationsdaten in Form von Bildern, Tönen, Filmsequenzen, Texten und/oder elektrischen oder Temperatur-Messwerten aufzeichenbar sind, wobei der Prozessor eingerichtet ist zum automatischen Durchführen eines Verfahrens mit den Schritten (i) Empfangen des verschlüsselten Positions-Signals vom Satellitennavigationssystem-Datenempfänger, (ii) Senden des verschlüsselten Positions- Signals zusammen mit einer Auftragskennung an einen räumlich beabstandeten Rechner, (iii) Empfangen eines in Reaktion auf das Senden des verschlüsselten Positions-Signals abgeschickten externen Schlüssels vom beabstandeten Rechner über eine sichere Verbindung, (iv) Empfangen von Dokumentationsdaten von der Aufzeichnungsvorrichtung und (v) Verschlüsseln der Dokumentsdaten anhand des externen Schlüssels. Based on this data, an additional plausibility test can be created, by means of which the determined position can be verified. In addition, according to the invention, a documenting device which, in addition to a satellite navigation system data receiver according to the invention, has a processor comprising a memory unit and a recording device can be recorded by means of the documentation data in the form of images, sounds, film sequences, texts and / or electrical or temperature measured values. the processor being arranged to automatically perform a method comprising the steps of (i) receiving the encrypted position signal from the satellite navigation system data receiver, (ii) transmitting the encrypted position signal along with a job identifier to a spatially-spaced computer, (iii) receiving a remote key sent from the remote computer in a secure connection in response to the transmission of the encrypted position signal, (iv) receiving documentation data from the recording device, and (v) encrypting the doc data using the external key.
Unter einem räumlich beabstandeten Rechner wird insbesondere ein Rechner verstanden, der in einer Entfernung von zumindest 10 Kilometern aufgestellt ist. A spatially-spaced computer is understood in particular to mean a computer which is set up at a distance of at least 10 kilometers.
Gemäß einer bevorzugten Ausführungsform ist der Prozessor eingerichtet zum automatischen Wiederholen zumindest von Schritt (i) in regelmäßigen Zeitabständen. Beispielsweise ist der Zeitabstand kleiner als eine Minute und das Wiederholen kann insbesondere bis zum Empfang eines Endsignals durchgeführt werden. According to a preferred embodiment, the processor is configured to automatically repeat at least step (i) at regular time intervals. For example, the time interval is less than one minute and the repetition can be carried out in particular until the reception of a final signal.
Unter einem Erfassen der Auftragsnummer wird insbesondere ein Empfangen der Daten von einem Dritten verstanden. By detecting the order number is meant in particular receiving the data from a third party.
Unter dem externen digitalen Schlüssel wird insbesondere ein Schlüssel mit mindestens 10 alphanumerischen Stellen verstanden, so dass eine hohe Verschlüsselungsstärke erreichbar ist. The external digital key is understood to mean, in particular, a key with at least 10 alphanumeric digits, so that a high encryption strength is achievable.
Unter dem Senden der Auftragsnummer und gegebenenfalls des externen Schlüssels an die erfindungsgemäße Dokumentiervorrichtung wird insbesondere ein elektronisches Übermitteln verstanden. By sending the order number and optionally the external key to the documenting device according to the invention is meant in particular an electronic transfer.
Das Ermitteln des Empfänger-Schlüssels aus der Seriennummer des Satellitennavigationssystem-Datenempfängers erfolgt vorzugsweise durch Abfragen einer, beispielsweise elektronischen, Datenbank, die beide Daten miteinander verknüpft. Diese Datenbank ist ein wichtiges Element der Erfindung und wird daher geheim gehalten. Determining the receiver key from the serial number of the satellite navigation system data receiver is preferably carried out by querying a, for example, electronic, database, which links the two data together. This database is an important element of the invention and is therefore kept secret.
Erfindungsgemäß ist zudem ein Verfahren zum Dokumentieren eines Zustande einer in oder an einem Gebäude installierten Vorrichtung, mit den Schritten (i) automatisches Empfangen von Satelliten-Funksignalen und Ermitteln einer absoluten Position aus den Satelliten-Funksignalen mittels eines Empfangsmoduls eines erfindungsgemäßen Satellitennavigationssystem-Datenempfängers, (ii) Berechnen von Positions-Signalen durch Verschlüsseln der absoluten Position mit einem digitalen Empfänger- Schlüssel, (iii) Versenden der verschlüsselten Positions-Daten an einen Zentralrechner, (iv) Empfangen eines externen digitalen Schlüssels, (v) Aufzeichnen von Dokumentationsdaten in Form von Bildern, Tönen, Filmsequenzen, Texten, elektrischen und/oder Temperatur-Messwerten mittels einer Aufzeichnungsvorrichtung, (v) automatisches Verschlüsseln der Dokumentationsdaten mit dem externen digitalen Schlüssel und (vi) Versenden der verschlüsselten Dokumentationsdaten an einen beabstandeten Rechner, insbesondere den Zentralrechner. Im Folgenden wird die Erfindung anhand der beigefügten Zeichnungen näher erläutert. Dabei zeigt According to the invention there is further provided a method of documenting a condition of a device installed in or on a building, comprising the steps of: (i) automatically receiving satellite radio signals and determining an absolute position from the satellite radio signals by means of a receiving module of a satellite navigation system data receiver according to the invention; ii) calculating position signals by encrypting the absolute position with a digital receiver key, (iii) sending the encrypted position data to a central computer, (iv) receiving an external digital key, (v) recording documentation data in the form of Images, sounds, film sequences, texts, electrical and / or temperature measurements by means of a recording device, (v) automatically encrypting the documentation data with the external digital key and (vi) sending the encrypted documentation data to a remote computer, especially the central computer. In the following the invention will be explained in more detail with reference to the accompanying drawings. It shows
Figur 1 eine schematische Ansicht eines erfindungsgemäßen Satellitennavigationssystem-Datenempfängers einer erfindungsgemäßen Dokumentiervorrichtung und Figure 1 is a schematic view of a satellite navigation system data receiver according to the invention a documenting device according to the invention and
Figur 2 zeigt schematisch, wie vom Empfangsmodul aus einem Datenstrom, der die absolute Position kodiert, die kodierte absolute Position erhalten wird. FIG. 2 schematically shows how the coded absolute position is received by the receiving module from a data stream which codes the absolute position.
Figur 1 zeigt einen erfindungsgemäßen Satellitennavigationssystem- Datenempfänger 10, der ein Empfangsmodul 12 und einen digitalen Speicher 14 umfasst. Der digitale Speicher 14 kann Teil des Empfangsmoduls 12 sein. Das Empfangsmodul 12 ist eingerichtet, um Satelliten- Funksignale 16 von einer Mehrzahl von Satelliten, von denen der Satellit 18 gezeigt ist, zu empfangen und daraus die absolute Position Pabs zu bestimmen. FIG. 1 shows a satellite navigation system data receiver 10 according to the invention, which comprises a reception module 12 and a digital memory 14. The digital memory 14 may be part of the receiving module 12. The receiving module 12 is arranged to receive satellite radio signals 16 from a plurality of satellites, of which the satellite 18 is shown, and to determine therefrom the absolute position P a bs.
Im digitalen Speicher 14 ist ein digitaler Empfänger-Schlüssel 20 gespeichert, mit dem die Daten, die die absolute Position Pabs kodieren, verschlüsselt werden. Das Empfangsmodul 12 ist eingerichtet zum automatischen Abgeben verschlüsselter Positions-Daten 22, die die absolute Position Pabs verschlüsselt als Position Pabs,kod kodieren. Die Positions-Daten 22 werden über eine Schnittstelle 24 abgegeben, die beispielsweise eine USB-Schnittstelle sein kann. Denkbar ist aber auch, dass die Schnittstelle eine Bluetooth-Schnittstelle ist oder eine Datenleitung umfasst, beispielsweise ein Datenkabel. Es ist auch möglich, dass die Schnittstelle 24 durch eine Steckverbindung mit einem Rechner gebildet ist. A digital receiver key 20 is stored in the digital memory 14, with which the data coding the absolute position P a bs are encrypted. The receiving module 12 is configured to automatically output encrypted position data 22 encoding the absolute position Pabs encoded as position P a bs, cod. The position data 22 are output via an interface 24, which may be, for example, a USB interface. It is also conceivable that the interface is a Bluetooth interface or includes a data line, such as a data cable. It is also possible that the interface 24 is formed by a plug connection with a computer.
Der digitale Empfänger-Schlüssel 20 ist im digitalen Speicher 14 unveränderbar gespeichert. Insbesondere ist der digitale Speicher 14 versiegelt, so dass der Empfänger-Schlüssel 20 nur durch Zerstören des digitalen Speichers 14 ermittelbar oder veränderbar ist. The digital receiver key 20 is stored in the digital memory 14 immutable. In particular, the digital memory 14 is sealed, so that the receiver key 20 can be determined or changed only by destroying the digital memory 14.
Der Satellitennavigationssystem-Datenempfänger 10 besitzt eine auslesbare Seriennummer 26, die auf ein nicht eingezeichnetes Gehäuse des Satellitennavigationssystem-Datenempfängers 10 eingeprägt ist. The satellite navigation system data receiver 10 has a readable serial number 26, which is stamped on an unmarked housing of the satellite navigation system data receiver 10.
Der Satellitennavigationssystem-Datenempfänger 10 ist Teil einer erfindungsgemäßen Dokumentiervorrichtung 28, die zusätzlich einen Prozessor 30, der eine Speichereinheit 32 umfasst, und zwei Aufzeichnungsvorrichtungen 34.1 , 34.2 aufweist. Die erste Aufzeichnungsvorrichtung 34.1 ist eine Kamera, mit der Bilder einer zu dokumentierenden technischen Vorrichtung 36 aufgenommen werden können. Die zweite Aufzeichnungsvorrichtung 34.2 ist ein Mikrofon, mit der Umgebungsgeräusche aufzei- chenbar sind. Weitere mögliche Aufzeichnungsvorrichtungen sind Voltmeter, Amperemeter, Widerstandsmessgeräte, Thermometer, Barkodescanner und RFI D-Leser. Auch weitere Aufzeichnungsvorrichtungen sind denkbar. The satellite navigation system data receiver 10 is part of a documenting device 28 according to the invention, which additionally has a processor 30, which comprises a memory unit 32, and two recording devices 34.1, 34.2. The first recording device 34.1 is a camera with which images of a technical device 36 to be documented can be recorded. The second recording device 34.2 is a microphone with which ambient noise can be recorded. Other possible recording devices include voltmeters, ammeters, ohmmeters, thermometers, barcode scanners, and RFI D readers. Other recording devices are conceivable.
Der Prozessor 30 ist eingerichtet zum automatischen Empfangen der verschlüsselten Positions-Signale 22 vom Empfangsmodul 12 und zum Senden dieses verschlüsselten Positions-Signals, das die verschlüsselte absolute Position Pabs, kod kodiert, mittels einer Sendevorrichtung 38 an einen räumlich beabstandeten Zentralrechner 40, der beispielsweise in einer anderen Stadt steht. Antwortet der Zentralrechner 40, so ist der Prozessor eingerichtet zum automatischen Empfangen eines externen Schlüssels 42 mittels einen diesen kodierenden Signals 44, zum Empfangen von Dokumentationsdaten von den Aufzeichnungsvorrichtung 34 und zum Verschlüsseln der Dokumentationsdaten anhand des externen Schlüssels 42, der nach Empfang in der Speichereinheit 32 abgelegt wird. The processor 30 is adapted to automatically receive the encrypted position signals 22 from the receiving module 12 and send this encrypted position signal, which encodes the encrypted absolute position P a bs, cod, to a spatially-spaced central computer 40 via a transmitting device 38 for example, in another city. When the central computer 40 responds, the processor is arranged to automatically receive an external key 42 by means of a signal 44 encoding it, to receive documentation data from the recording device 34 and to encrypt the documentation data based on the external key 42 after receipt in the memory unit 32 is filed.
Nach dem Beenden der Aufzeichnung oder auch während der Aufzeich- nung sendet die Dokumentiervorrichtung 28 die verschlüsselten Dokumentationsdaten beispielsweise an den Zentralrechner 40. Es ist sichergestellt, dass die auf dem Zentralrechner 40 liegenden Daten tatsächlich am Ort mit der absoluten Position Pabs aufgenommen wurden und damit zu der zu dokumentierenden technischen Vorrichtung 36 gehören. Der Hersteller der abzunehmenden Vorrichtung 36 kann also am entfernten Ort des Zentralrechners 40 bleiben und dennoch sicher sein, dass ein externer After the end of the recording or during the recording The documenting device 28 sends the encrypted documentation data to the central computer 40, for example. It is ensured that the data lying on the central computer 40 were actually recorded at the location with the absolute position P a bs and thus belong to the technical device 36 to be documented. The manufacturer of the device to be removed 36 can therefore remain at the remote location of the central computer 40 and still be sure that an external
Dienstleister am Ort der Vorrichtung 36 diese dokumentiert, ohne dass eine Manipulation möglich ist. Service provider at the site of the device 36 documents this, without any manipulation is possible.
Figur 2 zeigt schematisch, wie in dem Satellitennavigationssystem- Datenempfänger 10 unter Verwendung des Empfänger-Schlüssels 20 verschlüsselt wird. Der Empfänger-Schlüssel hat nur Zahlen von 0 bis 7. Das Empfangsmodul 12 umfasst einen Empfangschip 46, beispielsweise einen SirfStarlll-Chip, der von einer nicht eingezeichneten Antenne empfangene Satelliten-Signale in ein erstes digitales Signal 48 umsetzt. Das digitale Signal 48 wird von einem UART (universal asynchronous receiver trans- mitter) von einer Empfangsschaltung im Empfangschip 46 erzeugt. Figure 2 shows schematically how in the satellite navigation system data receiver 10 is encrypted using the receiver key 20. The receiver key has only numbers from 0 to 7. The receiving module 12 comprises a receiving chip 46, for example a SirfStarIII chip, which converts satellite signals received from a non-drawn antenna into a first digital signal 48. The digital signal 48 is generated by a UART (universal asynchronous receiver transmitter) from a receiving circuit in the receiving chip 46.
Dieses erste Signal 48 enthält in jedem Telegramm ein Datenbyte an Nutzlast und gelangt zu einem MikroController 50, der den digitalen Speicher 14 umfasst. Anhand der Schlüsselfolge 3603 wird das beispielhafte Verschlüsselungsverfahren erläutert. This first signal 48 contains in each telegram a data byte of payload and arrives at a microcontroller 50 which comprises the digital memory 14. The key sequence 3603 explains the exemplary encryption method.
So ist das erste Byte des Signals 48 gezeigt. Die erste Stelle des Empfänger-Schlüssels 20 ist eine„3", betrachtet wird also das Bit an Stelle 3. Da die„3" eine ungerade Zahl ist, wird die dritte Stelle des ersten Bytes invertiert, so dass aus der 1 eine 0 wird. Wäre das Bit an der dritten Stelle eine „0", würde es in eine„1" geändert. Thus, the first byte of the signal 48 is shown. The first digit of the receiver key 20 is a "3", so the bit is considered in place 3. Since the "3" is an odd number, the third digit of the first byte is inverted so that 1 becomes 0 , If the bit in the third position were a "0", it would be changed to a "1".
Das zweite Byte des Signals 48 ist ebenfalls dargestellt. Da die zweite Stelle des Empfänger-Schlüssels 20 eine„6" ist, also eine gerade Zahl, wird das Bit an Stelle 6 (hier eine„1") mit dem nachfolgenden Bit (hier auch eine„1") getauscht. The second byte of the signal 48 is also shown. Since the second digit of the recipient key 20 is a "6", an even number, the bit at location 6 (here a "1") is exchanged with the following bit (here also a "1").
Die dritte Stelle des Empfänger-Schlüssels 20 ist eine„0", die zwar eine gerade Zahl ist, aber als ungerade Zahl behandelt wird. Daher wird das Bit an der Stelle„0" (hier eine„1") mit der nachfolgenden Stelle getauscht. The third digit of the receiver key 20 is a "0", which is an even number but is treated as an odd number, so the bit at location "0" (here a "1") is swapped with the following digit ,
Durch diese Verschlüsselung, die rein exemplarisch ist und durch eine beliebige andere Verschlüsselung ersetzt werden könnte, wird ein zweites Signal 52 erhalten, das an die Schnittstelle 24 (vgl. Figur 1) geleitet wird. By this encryption, which is purely exemplary and could be replaced by any other encryption, a second signal 52 is obtained, which is passed to the interface 24 (see Figure 1).
Figur 1 zeigt zudem schematisch, wie ein erfindungsgemäßes Verfahren durchführbar ist. Zunächst wird eine Auftragsnummer 54 von einem Auftragserteilungsrechner 56 vom Zentralrechner 40 empfangen. Es wird zudem die Seriennummer 26 erfasst, beispielsweise indem diese vor einem Versand des Satellitennavigationssystem-Datenempfängers 10 abgeschrieben und gespeichert wird. In einem zweiten Schritt wird der externe digitale Schlüssel 42 erzeugt, beispielsweise mittels eines Zufallsgenerators, und die Verknüpfung zwischen der Auftragsnummer 54 und dem digitalen Schlüssel 42 wird in einer nicht eingezeichneten Datenbank abgelegt. In einem dritten Schritt wird die Auftragsnummer 42 an die Dokumentiervorrichtung 28 gesendet. Es ist möglich, dass auch der externe Schlüssel 42 versendet wird. In einem vierten Schritt werden von der Dokumentiervorrichtung 28 die verschlüsselten Positions-Signale empfangen, die mit der Auftragsnummer verknüpft sind. FIG. 1 additionally shows schematically how a method according to the invention can be carried out. First, an order number 54 is received from an order issuing computer 56 from the central computer 40. In addition, the serial number 26 is detected, for example by being written off and stored before a shipment of the satellite navigation system data receiver 10. In a second step, the external digital key 42 is generated, for example by means of a random number generator, and the link between the order number 54 and the digital key 42 is stored in a database not shown. In a third step, the order number 42 is sent to the documenting device 28. It is possible that the external key 42 is also sent. In a fourth step, the documenting device 28 receives the encrypted position signals associated with the job number.
In einem fünften Schritt wird aus der Seriennummer 26 der Empfänger- Schlüssel 20 des Satellitennavigationssystem-Datenempfängers 10 bestimmt. Dieser Empfänger-Schlüssel 20 ist bei der Herstellung des Satellitennavigationssystem-Datenempfängers 10 gespeichert worden und mit der Seriennummer 26 in einer Datenbank verknüpft worden. Diese Datenbank wird vom Betreiber des Zentralrechners 40 geheim gehalten und stellt die Gewähr dafür dar, dass die aufgenommenen Dokumentationsdaten nicht manipulierbar sind. In a fifth step, the receiver key 20 of the satellite navigation system data receiver 10 is determined from the serial number 26. This receiver key 20 has been stored in the manufacture of the satellite navigation system data receiver 10 and has been linked to the serial number 26 in a database. This database is kept secret by the operator of the central computer 40 and represents the guarantee that the recorded documentation data are not manipulable.
In einem sechsten Schritt wird ermittelt, ob das verschlüsselte Positions- Signal anhand des Empfänger-Schlüssels dekodierbar ist. Ist das der Fall, wurde das Positions-Signal vom korrekten Satellitennavigationssystem- Datenempfänger 10 verschlüsselt, nämlich von dem mit der Seriennummer 26. Ist das der Fall, so wird der externe Schlüssel 42 an die Dokumentiervorrichtung 28 versendet. Schließlich werden die anhand des digi- talen Schlüssels 42 verschlüsselten Daten von der Dokumentationsvorrichtung 28 empfangen. In a sixth step, it is determined whether the encrypted position signal can be decoded using the receiver key. If so, the position signal has been encrypted by the correct satellite navigation system data receiver 10, namely serial number 26. If so, the external key 42 is sent to the documenter 28. Finally, the data encrypted on the basis of the digital key 42 is received by the documentation device 28.
