摘要:
详细阐述了制动系统提供零速信号或非零速信号的串联及并联使用特点，根据信号真值表，深入讨论了不同组合方式的安全性及弊端，以及给列车运行带来的安全隐患。综合分析了各组合方案的安全性。根据分析结果，并联使用非零速信号方案是安全性最高的制动控制单元信号方案，建议城市轨道交通车辆在电气原理设计时应选用制动系统提供的非零速信号作为车辆的控制信号。
Abstracts:
Series or parallel operation characteristics of zero speed and non-zero speed signals provided by braking system are expounded in detail. According to the signal true table, the safety and concerns of different combination are discussed in-depth, as well as safety hazards brought about to train operation. The safety of each combination scheme is analyzed comprehensively. According to analysis results, the scheme of non-zero speed signal in parallel operation is the brake control unit signal scheme with the highest safety. It is suggested to adopt the non-zero speed signal provided by braking system as the vehicle control signal in the electrical principle design of urban rail transit vehicle.
