Railway interlocking system by means of a software architecture and its process of implementation

摘要

The control system allows the safe movement of trains over the railway network which comprises a number of piece of line equipment. The system includes a number of tasks (Trc-AEA) associated with each of the pieces of line equipment respectively. The tasks form a distributed logic system enabling the establishment of journeys along permitted free routes. A series of logic channels (6) enable the tasks to communicate by propagation of messages following the specific geographical topology of the railway network. The implementation of the system is achieved by computer processing of a file which describes the network, and a library of generic modules each implementing a specific automated process.
