This study presents an electronic interlock safety aid system design programs to improve and enhance the safety, reliability and stability of the railway signal interlocking system. The existing relay interlocking system semaphore line can not to precision control and maintain, data can not be stored and interpretation analysis, and railway transport system to security is paramount. Therefore, how to combine all of the existing railway station relay interlocking semaphore system, the addition of an electronic interlocking safety system, became an important issue in this article. The system needs to have: (1) Signal equipment operation record. (2) Records of the abnormal information and analysis, through analysis of materials and parts to reduce inventory levels, reduce costs and reduce construction costs preparation reduce testing time of construction. (3) Instant fault alarm system to support maintenance personnel and reduce workload. (4) The age of the equipment, electrical life estimation and alarms. Using Petri Nets based design method, developed above subsystems to complete an "electronic interlocking safety support system" to achieve several important goals:
(1) To enhance the security, the reliability and stability of the original interlock semaphore system.
(2) To introduce modular ways for software and hardware design, to facilitate future maintenance.
(3) To shorten the semaphore system repair, testing process, improve service punctuality of trains.
(4) To reduce maintenance time and preparation of construction costs and improve construction efficiency.
Once the entire "electronic interlocking safety support system" development is complete, this study will reveal to Station Taitung and Zhiben to the subject, introducing the semaphore station electronic interlocking system to verify that the system can achieve these goals. Finally, demonstrate the performance of the new system with existing systems for cross-comparison analysis and verify the correctness and feasibility of the proposed method. This study can significantly improve the efficiency of train punctuality rate and reduce equipment failure rates.
