摘要:
基于逃生门控制原理，阐述了逃生门功能检测及故障诊断的策略及具体实施方法。在全自动运行列车投入正线运营前，通过列车控制及诊断系统的软件逻辑控制，强制逃生门完成一次可锁闭和可打开的功能测试。通过硬线电路设计，在逃生门检测脉冲信号作用下使零速信号由旁路传递，从而区分开逃生门的打开和故障状态。基于逃生门电磁锁的状态反馈，实现对逃生门的功能检测和故障诊断。仿真验证结果表明，逃生门的功能检测可保证逃生门的功能完善，确保其在列车全自动运行中的可用性和可靠性。
Abstracts:
According to the control principle of escape door, the strategy and specific implementation method of escape door function detection and fault diagnosis are described. Before the FAO (fully automatic operation) train is launched for operation on main line, through software logic control of train control and diagnosis system, the escape door is forced to complete once locking and opening function test. The zerospeed signal is bypassed by the action of escape door detection pulse signal through hardwired circuit design to distinguish between the opening and fault states of the escape door. Based on the feedback of escape door electromagnetic lock state, the escape door function detection and fault diagnosis are realized. Simulation test results show that the function detection of the escape door can improve its functions，ensure its availability and reliability in train fully automatic operation.
