Process and device for control and monitoring a traffic control system
First Claim
1. A process for controlling and monitoring of a traffic control system, the system having actuators, monitoring units and at least two tracks for rail vehicles, comprising:
- blocking, by a control process, all of a plurality of actuators corresponding to a requested travel route against further requests to allocate further travel routes and further control operations, upon request for allocation of a requested travel route;
testing, by a test process, whether one of the actuators and monitoring units to be blocked and actuated for the allocation and release of a requested travel route, are being used for a previously allocated requested travel route, and are thus already blocked, the test process being independent of the control process; and
setting each actuator in correspondence with the requested travel route.

Abstract
Process and device for controlling and monitoring of a traffic control system which has actuators and monitoring elements and by means of which at least two traffic tracks for railborne vehicles can be controlled by a control process which, upon request for allocation of a route, blocks all the actuators belonging to this route against other requests to create additional routes and control operations and carries out the request. To that effect, each of the changes in the positions or conditions of the actuators to be carried out by the control process, takes place only after successful testing for permissibility by a test process which is independent of the control process and which, in each case, tests whether the actuators and/or monitoring elements to be blocked or to be actuated for the allocation or release of the route already are in use and, thus, have been blocked.

14. A device for controlling and monitoring of a traffic control system, the system having actuators, monitoring units and at least two tracks for rail vehicles, the device comprising:
-
a control process system configured to operate a control process, the control process adapted to block all of a plurality of actuators corresponding to a requested travel route against further requests to allocate further travel routes and further control operations, upon request for allocation of a requested travel route; a test process system configured to operate a test process, the test process system being independent of said control process system; and a controller adapted to control said control process system and said test process system. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28)
