Die Erfindung betrifft eine Prozessanschaltung für das sichere Betreiben von sicherungstechnischen Einrichtungen gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a process connection for the safe Operating safety equipment according to the preamble of claim 1.

Prozessanschaltungen sind als Stellteile von elektronischen Stellwerken bekannt, wobei die Stellteile die Komponenten der Innenanlage und der Außenanlage des Stellwerks steuern und überwachen. Dazu sind die Komponenten mit einem sicheren Rechner verbunden, was über separate Verbindungen erfolgt, die an dafür vorgesehenen separaten Eingängen des sicheren Rechners angeschlossen sind. Diese Art der Verbindung wird auch als Punkt-zu-Punkt-Verbindung bezeichnet (jede Verbindungsleitung ist jeweils mit einem Kontakt des zugehörigen Eingangs des sicheren Rechners und der Komponente verbunden). Nachteilig ist dabei der relativ große Schaltungsaufwand.Process connections are as control elements of electronic Interlockings known, the actuators are the components of Control indoor and outdoor facilities of the signal box and monitor. These are the components with a safe Computer, which is done via separate connections, the dedicated separate inputs of the secure Computers are connected. This type of connection will also referred to as a point-to-point connection (each trunk is each with a contact of the associated Input of the secure computer and the component connected). The disadvantage here is the relatively large circuit complexity.

Zur Herstellung der Stellteile ist heute eine große Anzahl spezifischer Stellteilbaugruppen erforderlich. Dabei wächst die Anzahl der Stellteile stetig, da häufig kundenabhängige Speziallösungen erforderlich sind, wobei auch kleinere Änderungen der vorhandenen Stellteile immer noch einen erheblichen Aufwand erfordern, insbesondere da stets eine neue Sicherheitsnachweisführung erfolgen muss.For the production of the control parts is today a large number specific actuator subassemblies required. It grows the number of actuators steadily, as often customer-dependent Special solutions are required, with minor changes as well the existing controls still a considerable Require effort, especially as always a new safety record guide must be done.

Der Erfindung liegt die Aufgabe zugrunde, die Zahl der Verbindungsleitungen zu verringern.The invention is based on the object, the number of connecting lines to reduce.

Die Lösung dieser Aufgabe wird durch die im Anspruch 1 angegebenen Merkmale gegeben. Durch die kennzeichnenden Merkmale der Unteransprüche ist die Prozessanschaltung in vorteilhafter Weise weiter ausgestaltet. The solution to this problem is specified by the claim 1 Given characteristics. By the characteristic features the subclaims, the process connection is in an advantageous Way further designed.

Die Lösung sieht vor, dass miteinander kombinierbare Funktions-Module vorgesehen sind, deren Funktionalitäten jeweils unterschiedlichen Prozessanschaltungen gemeinsam sind, insbesondere die Funktionalitäten von Prüfschaltungen, Leistungsschaltern, Filtern, digitalen Ein- und Ausgängen, Rechnern und Kommunikationsschnittstellen, dass zumindest ein Funktions-Modul ein sicherer Rechner ist und dass die Kommunikation des sicheren Rechners mit den übrigen Funktions-Modulen über einen seriellen Bus erfolgt.The solution provides that combinable function modules are provided whose functionalities each different process connections are common, in particular the functionalities of test circuits, circuit breakers, Filters, digital inputs and outputs, computers and communication interfaces that at least one function module a secure computer is and that communication of the secure computer with the other function modules via a serial bus.

Technisch einfach ist es, wenn die Kommunikation zwischen dem Rechner und den Funktions-Modulen über den seriellen Bus in Form von Telegrammen erfolgt.It is technically easy when the communication between the Computer and the function modules via the serial bus in Form of telegrams.

Vorteilhafterweise umfasst die Kommunikation mit den Funktions-Modulen den Datenaustausch und die Ansteuerung sowie die Statusabfrage der Funktions-Module.Advantageously, the communication with the functional modules includes the data exchange and the control as well the status query of the function modules.

Zur Erzielung der gewünschten Sicherheit ist der sichere Rechner zweikanalig aufgebaut.To achieve the desired safety is the safe Computer built up two channels.

Die Zahl der Verbindungsleitungen lässt sich deutlich verringern, trotz kostengünstiger kundenabhängiger Speziallösungen, wenn die Prozessanschaltung als Stellteil ausgebildet ist, auf dem sich der sichere Rechner befindet, während die Funktions-Module an den zu überwachenden und zu steuernden Komponenten, beispielsweise an den Signalen, Weichenantrieben und dergleichen, angeordnet sind.The number of connecting lines can be significantly reduced, despite cost-effective customer-specific special solutions, if the process connection is designed as an actuating part, on which the secure computer is located, while the functional modules on the components to be monitored and controlled, For example, on the signals, points drives and like, are arranged.
