| Abstract: | The railway signaling computer-based interlocking system is a safety-critical system that requires high reliability, safety and real-time performance. We have designed and developed SWJTU-II, a fault-tolerant computer-based interlocking system that meets the requirements of high reliability, safety and real-time performance. The hardware of SWJTU-II adopts SIEMENS-produced PLC as the main control components, adopts the redundancy stand-by structure and can finish fault-switching without disturbance. The interlocking software of SWJTU-II is modeled by Petri nets, designed by the object-oriented method and coded by the Step 7 STL program language. The simulation software is used to simulate the train moving process and the system is proved good in operation. The SWJTV-II system has been put into wide application. |
