Verfahren und Anordnung zur Überwachung eines sicherheitsrelevanten ProzessesMethod and arrangement for monitoring a safety-relevant process
Die Erfindung betrifft ein Verfahren zur Überwachung eines sicherheitsrelevanten Prozesses, insbesondere Bahnbetriebs¬ prozesses, bei dem Zustandsgrößen des Prozesses durch die Darstellung mindestens eines Symbols zur Anzeige gebracht werden sowie eine Anordnung zur Durchführung des Verfahrens.The invention relates to a method for monitoring a safety-relevant process, in particular Bahnbetriebs ¬ process are brought in the state variables of the process by displaying at least one symbol for display and an arrangement for performing the method.
Bedienplatzsysteme für sicherheitsrelevante Prozesse müssen hohe Sicherheitsanforderungen, sowohl hinsichtlich des aktuell auszuführenden Prozesses als auch hinsichtlich der Funk- tionsfähigkeit der Bedien- und Anzeigeelemente erfüllen. Vor der Eingabe von sicherheitsrelevanten Kommandos an Bedienplätzen, beispielsweise in einem Stellwerk, muss sich der Bediener von der Korrektheit der Anzeige des aktuellen Prozess¬ standes überzeugen. Bei bekannten Systemen sind dazu ver- schiedene durch Symbole dargestellte Zustandsgrößen des Pro¬ zesses vorgesehen, die der Bediener vor einer Kommandofreigäbe visuell überprüfen muss. Das betrifft insbesondere die Ak¬ tualität des Prozessstandes durch Beobachtung eines Aktuali¬ sierungsmelders, die Korrektheit der Farben durch Beobachtung eines Farbmusters, die Blinkfähigkeit durch Beobachtung eines blinkenden Farbmusters, die korrekte Gitterdarstellung durch Beobachtung eines Gittermusters und die Helligkeitsabsenkung durch Beobachtung eines Helligkeitswechsels. Diese separaten Anzeigen symbolisieren die Funktionsfähigkeit des Gesamtsys- tems charakterisierende Zustandsgrößen des Prozesses. Erst wenn sämtliche Anzeigen in der vorgegebenen Form bzw. Farbe erscheinen, ist die Freigabe des von dem Bediener vorgewählten oder vom System vorgegebenen Kommandos zulässig. Diese 2005 P 05265 DEOperator station systems for safety-relevant processes must fulfill high safety requirements, both with regard to the currently executing process and with regard to the functionality of the operating and display elements. Before entering security-related commands to operator stations, for example in a signal box, the operator of the accuracy of the display of the current state ¬ process must be convincing. In known systems, to comparable different state variables of the Pro ¬ zesses represented by icons are provided, the need to check the operator before a Kommandofreigäbe visually. This concerns in particular the Ak ¬ tualität of the process object by observation of a Aktuali ¬ sierungsmelders, the correctness of the colors by observation of a color pattern, the flashing ability by observing a flashing color pattern, the correct mesh representation by observing a grid pattern and the brightness reduction by observing a change in brightness. These separate displays symbolize the process variables of the process which characterize the functioning of the overall system. Only when all displays appear in the specified form or color, the release of the preselected by the operator or given by the system command is permissible. These 2005 P 05265 DE
Bedienung ist ergonomisch sehr konzentrationsaufwendig und infolge dessen auch fehleranfällig.Operation is ergonomically very concentration intensive and as a result also error prone.
Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren der gattungsbildenden Art anzugeben, das ergonomisch günstiger ist und trotzdem hohen Sicherheitsanforderungen genügt.The invention has for its object to provide a method of the generic type, which is ergonomically cheaper and still meets high safety requirements.
Erfindungsgemäß wird die Aufgabe gelöst, indem wenigstens ein Symbol mehrere Zustandsgrößen gleichzeitig darstellt. Durch die Konzentration mehrerer - möglichst sämtlicher - Zustandsgrößen in einem einzigen Symbol ergibt sich eine zuverlässi¬ gere Kontrollmöglichkeit durch den Bediener. Der Bediener muss nur noch das Symbol beobachten, dessen Erscheinungsbild ihm aufgrund der Vertrautheit nach kurzer Eingewöhnungszeit quasi mit einem Blick die erforderliche Sicherheit gibt, dass die Kommandofreigabe erfolgen kann. Letztlich resultiert durch die Ein-Symbol-Kontrolle eine Verbesserung der betrieb¬ lichen Sicherheit.According to the invention, the object is achieved by at least one symbol representing a plurality of state variables simultaneously. By concentrating more - of all possible - state variables in a single symbol, a zuverlässi ¬ Gere control possibility is given by the operator. The operator only has to observe the symbol, whose appearance gives it, with a glance, the necessary certainty that the command can be released, due to its familiarity after a short familiarization period. Ultimately resulted by the one-symbol control to improve the operational ¬ comprehensive safety.
Vorteilhafterweise wird das Erscheinungsbild des Symbols von Ansteuermitteln erzeugt, die in Abhängigkeit von den zu überwachenden Sicherheitskriterien entsprechende Ausgangssignale erzeugen. Beispielsweise kann das Symbol ein Betreiberlogo in den Grundfarben rot, gelb und blau sein. Damit lässt sich die Farbechtheit prüfen. Dieses Betreiberlogo kann rotierend an¬ gesteuert werden, wodurch Aktualität symbolisiert wird. Ein Umlauf könnte z. B. 1 bis 3s dauern. Nach jeder Rotation könnte das Betreiberlogo durch eine weitere Ansteuerung ein¬ mal blinken. Im Hintergrund des Logos kann kontinuierlich ei- ne Helligkeitsänderung erfolgen. Außerdem kann eine Ansteuerung vorgesehen sein, durch die vor jeder Kommandofreigabe- Bedienung ein Gittermuster über das Logo gelegt wird. Alternativ könnte das Gittermuster über einen zur Kommandofreigabe 2005 P 05265 DEAdvantageously, the appearance of the symbol is generated by activation means which generate corresponding output signals as a function of the safety criteria to be monitored. For example, the symbol may be an operator logo in the primary colors red, yellow and blue. This can be the color fastness check. This operator logo can be controlled in a rotating manner, whereby actuality is symbolized. A circulation could z. B. 1 to 3s last. After each rotation, the operator logo could flash once more by a further activation. In the background of the logo, a brightness change can take place continuously. In addition, a control can be provided by which a grid pattern is placed over the logo before each command release operation. Alternatively, the grid pattern could be one for command release 2005 P 05265 DE

Nachfolgend wird die Erfindung anhand einer figürlichen Darstellung näher beschrieben.The invention will be described in more detail with reference to a figurative representation.
Die Figur zeigt ein Symbol zur Visualisierung sicherheitsre¬ levanter Prozesse.The figure shows a symbol for the visualization sicherheitsre ¬-relevant processes.
Dargestellt ist ein Signal in Form eines Logos 1, das z. B. den Betreiber oder das Produkt kennzeichnen kann. Hier ist eine Buchstabenfolge BPS gewählt, wobei das B rot, das P gelb/grün und das S blau angesteuert werden. Gegebenenfalls können diese in den Grundfarben dargestellten Buchstaben und/oder deren Umgebung mit einem feinen Gittermuster unter- legt sein. Ein weiteres Sicherheitskriterium wird durch einen ein bis drei Sekunden-Umlauf 2 veranschaulicht. Nach jedem Umlauf 2 kann zusätzlich ein kurzes Blinken vorgesehen sein. Die Aktualität der Anzeige ist durch eine um das Logo 1 ro¬ tierende Ellipse 3 ausgedrückt. Alternativ kann das Logo 1 auch auf einer Fahne dargestellt sein, die zur Aktualitätsanzeige flatternd erscheint. Das Logo 1 ist mit einem Schatten 4 mit Helligkeitsänderung versehen, wodurch ein weiteres Sicherheitskriterium angezeigt wird.Shown is a signal in the form of a logo 1, the z. B. can identify the operator or the product. Here a letter sequence BPS is selected, whereby the B red, the P yellow / green and the S blue are controlled. If appropriate, these letters represented in the basic colors and / or their surroundings may be backed by a fine grid pattern. Another safety criterion is illustrated by one to three seconds of circulation 2. After each revolution 2, a short blinking may additionally be provided. The timeliness of the display is expressed by the logo 1 ro ¬ animal end ellipse. 3 Alternatively, the logo 1 may also be displayed on a flag that appears fluttering to the actuality display. The logo 1 is provided with a shadow 4 with brightness change, whereby a further safety criterion is displayed.
