Abstract

The method involves measuring noise levels during a pause in the warning signals and storing this as a reference noise value. The level of the warning signals (25,55) are then measured during the period when the warning apparatus is active. During this period, the warning signals are adjusted until their measured level exceeds the previously stored noise value by a preset amount. There is also an Independent claim to an apparatus for carrying out the method.

Nachfolgend werden Ausführungsbeispiele der Erfindung anhand der Zeichnung näher erläutert. Es zeigt

  • Fig. 1 ein Warngerät mit zwei identischen Funktionsgruppen.
    • Exemplary embodiments of the invention are explained in more detail below with reference to the drawing. It shows
  • Fig. 1 is a warning device with two identical function groups.

    • In Fig. 1 ist eine typische Schaltung einer verdoppelten Funktionsgruppe 1,51 mit je den Mitteln 3- 11 eines Warngeräts dargestellt. Die Funktionsgruppe 1, beziehungsweise 51 des Warngeräts ist je für sich allein betriebsfähig. Die Funktionsgruppe 51 ist vereinfacht dargestellt. Ein Signalgenerator 5a gibt während der Warnung durch eine Steuerung 3 über eine Leitung 35 vorgegebene Signale über einen Regler 5 an den Wandler 7 ab, der die Signale 37 in die zu emittierenden Warnsignale 25,55 wandelt und abgibt. Ein Sensor 9 mißt die Immission 27,57, die physikalisch dem Warnsignal 25,55 äquivalent ist. Die vom Sensor 9 gemessene Immission gelangt über eine Leitung 29 an den Regler 5 und an den Störwertspeicher 11, dessen Eingang in den Warnpausen - vorzugsweise nur unmittelbar vor einer Warnung - von der Steurung 3 durch eine Verbindung 31 freigegeben wird, sodaß der Störwertspeicher 11 nur den warnsignalfreien Störwert speichern kann. Während der Warnzeit wird der Regler 5 durch die Verbindung 31 von der Steuerung freigegeben und stellt den Pegel der Signale 37 an seinem Ausgang so ein, bis die dabei gemessene Immission 27,57,9,29 des Warnsignals 25,55 einen vorbestimmten Wert höher ist als der zuvor im Störwertspeicher 11 gespeicherte Wert der Umweltstörung, der ihm über eine Leitung 33 zugeführt wird. Der vorbestimmte Wert kann absolut oder zum Beispiel ein Quotient der beiden verglichenen Werte sein, wobei ein Korrekturwert bezüglich des Warnsignals 25,55 für die möglicherweise geringe Distanz zwischen Wandler 7 und Sensor 9 einbezogen sein kann. 1 shows a typical circuit of a doubled function group 1.51, each with the means 3-11 of a warning device. Function group 1 or 51 of the warning device can each be operated on its own. The function group 51 is shown in simplified form. During the warning, a signal generator 5a outputs predetermined signals via a line 35 via a controller 35 to the converter 7, which converts the signals 37 into the warning signals 25, 55 to be emitted and outputs them. A sensor 9 measures the immission 27, 57, which is physically equivalent to the warning signal 25, 55. The immission measured by the sensor 9 reaches the controller 5 and the fault value memory 11 via a line 29, the input of which is released by the control 3 through a connection 31 during the pauses in the warning - preferably only immediately before a warning - so that the fault value memory 11 only can save the warning-free fault value. During the warning time, the controller 5 is released by the controller through the connection 31 and adjusts the level of the signals 37 at its output until the measured immission 27, 57, 9, 29 of the warning signal 25, 55 is a predetermined value higher than the value of the environmental disturbance previously stored in the fault value memory 11, which value is fed to it via a line 33. The predetermined value can be absolute or, for example, a quotient of the two compared values, a correction value with regard to the warning signal 25, 55 for the possibly short distance between transducer 7 and sensor 9 being included.

    Der Regler 5 kann den Signalgenerator 5a enthalten oder ein regelbarer Signalgenerator (5,5a) sein, wobei die Verbindung 23 zwischen den Mitteln 5,5a entfällt. Die Steuerung 3 kann weitere, an sich bekannte und übliche, nicht näher dargestellte Mittel zur Einleitung der Warnung enthalten und/oder über ihren Eingang 21 gesteuert oder fernbedient werden. Der Störwertspeicher 11 kann zum Beispiel ein Kondensator mit Entladewiderstand oder ein digitaler Speicher sein. Die Mittel 3-11 können analog oder digital arbeiten oder Teil eines Prozessors mit seiner Peripherie sein. Der Sensor 9 kann ein bewertendes Filter aufweisen, um zum Beispiel den Immissionswert 27,57 zu normieren.The controller 5 can contain the signal generator 5a or a controllable signal generator (5.5a), the connection 23 between the means 5.5a being eliminated. The control 3 can further, known and customary, not shown means of introduction contain the warning and / or be controlled or remotely controlled via its input 21. The fault value memory 11 can be, for example, a capacitor with a discharge resistor or be digital storage. The means 3-11 can work analog or digital or part of a processor with its periphery. The sensor 9 can be a rating filter have, for example to normalize the immission value 27.57.

    Bei einer sicheren Warnung muß der Pegel des Warnsignals 25,55 über dem der Umweltstörung liegen, um die Wahrnehmung des Warnsignals zu gewährleisten. Trotzdem sollte das Warnsignal nicht unnötig intensiv sein. Probleme machen hier insbesondere unzulässige Abweichungen der Wandler- und Sensoreigenschaften 7,9 während des Betriebs, zum Beispiel durch Verschmutzung. Bei dem hier dargestellten Verfahren werden jedoch die ständig aktualisierten Immissionen 27,57 sowohl der Umweltstörung als auch des Warnsignals über den gleichen Sensor 9 gemessen, sodaß Veränderungen der Eigenschaften des Sensors 9 kompensiert werden. Gleichzeitig werden Veränderungen der Eigenschaften des Wandlers 7 kompensiert, da er in den Regelkreis 5,7,9 einbezogen ist.In the event of a safe warning, the level of the warning signal must be 25.55 above that of the Environmental disturbance lie to ensure the perception of the warning signal. Nevertheless the warning signal should not be unnecessarily intense. Problems arise here in particular impermissible deviations in the transducer and sensor properties during the 7.9 Operating, for example due to pollution. In the procedure shown here however, the continuously updated emissions 27.57 of both the environmental disturbance and the Warning signal measured by the same sensor 9, so that changes in properties of the sensor 9 can be compensated. At the same time, changes in properties of the converter 7 compensated because it is included in the control loop 5,7,9.

    Wenn sich der Wirkungsgrad der Wandlung 7 der Warnsignale 25,55 verschlechtert, nimmt der Pegel der Signale 37 am Ausgang des Reglers durch die Kompensation zu, bis er schließlich einen vorbestimmten Grenzwert erreicht. Die Steuerung 3 vergleicht den Pegel der Signale 37 mit dem vorbestimmten Grenzwert und veranlaßt bei Überschreiten des Grenzwertes den Signalgenerator 5a über die Leitung 35 zur Abgabe eines Störsignals. Gleichzeitig wird die Warnung 7,25,55 durch die Steuerung 3 freigegeben, wenn das Störsignal am Ausgang 25,55 emittiert werden soll.If the efficiency of the conversion 7 of the warning signals 25, 55 deteriorates, the level of the signals 37 at the output of the controller increases due to the compensation until it finally reaches a predetermined limit. The controller 3 compares the level of the signals 37 with the predetermined limit value and causes when the Limit value the signal generator 5a via line 35 to emit an interference signal. At the same time, the warning 7,25,55 is released by the controller 3 if that Interference signal to be emitted at output 25.55.

    Um Ausfälle in der gesamten Funktionsgruppe 1 mit ihren Mitteln 3-11 erkennen zu können, ist mindestens eine zweite, gleichartige Funktionsgruppe 51 vorgesehen, wobei die Signale 37 während der Warnzeit über die Steuerungen 3 in den Funktionsgruppen 1,51 gegenseitig über eine Leitung 41 übermittelt und miteinander verglichen werden. Bei Abweichungen der Parameter der Signale 37 wie zum Beispiel Pegel, Dauer oder Frequenzen über einen vorbestimmtes Maß hinaus liegt ein Ausfall vor und die Steuerungen 3 veranlassen über die Leitung 35 im Signalgenerator 5a eine Störwarnung.To detect failures in the entire functional group 1 with their means 3-11 can, at least a second, similar functional group 51 is provided, the Signals 37 during the warning time via the controls 3 in the function groups 1.51 are transmitted to one another via a line 41 and compared with one another. At Deviations in the parameters of the signals 37 such as level, duration or Frequencies beyond a predetermined level, there is a failure and the controls 3 cause a fault warning via line 35 in signal generator 5a.

    Da sich die Emissionen 25,55 mehrerer Wandler 7 überdecken können, ist zur Einzelkontrolle der Wandler 7 vorgesehen, daß diese durch die Steuerungen 3 über eine Leitung 39 abwechselnd selektiv freigegeben werden. Die Signale 37 werden dabei in den Steuerungen 3 verzögert gespeichert, damit das bereits ausgeregelte Signal 37 erfaßt wird. Bei jeder neuen Freigabe eines Wandlers 7 werden durch die Steuerungen 3 die Signale 37 der verschiedenen Wandler miteinander verglichen. Bei unzulässigen Abweichungen wird eine Störwarnung veranlaßt.Since the emissions 25.55 of several converters 7 can overlap, Individual control of the transducer 7 provided that this through the controls 3 via a Line 39 are alternately selectively released. The signals 37 are in the Controls 3 are stored with a delay so that the signal 37, which has already been corrected, is detected. With each new release of a converter 7, the signals 37 of the different converters compared. In the event of impermissible deviations causes a malfunction warning.

    Die Wandler 7 können unterschiedlicher physikalischer Art sein und zum Beispiel akustische, optische oder mechanische Warnsignale 25,55 oder eine Kombinationen davon abgeben, wobei jeweils ein Paar aus je einem Wandler 7 und einem Sensor 9 physikalisch äquivalent zueinander sind.The transducers 7 can be of different physical types and for example acoustic, optical or mechanical warning signals 25.55 or a combination thereof deliver, each a pair of a transducer 7 and a sensor 9 physically are equivalent to each other.
