EI32-JD型计算机联锁是二乘二取二系统,具备“故障-安全”性能,其关键部分均采用双套热备,保证故障时不间断使用。郑州电务段管内京广线大量使用该设备,其接口电路是现场维护的重点,也是易发生故障的部位。1驱动采集故障1.如果发生了微机驱动的继电器不动作,在办理操作时,测量
The EI32-JD computer interlocking system is a two-by-two-two system with “fail-safe” performance. The key parts of the EI32-JD are dual-system hot backup, ensuring uninterrupted use when faults occur. Zhengzhou Electrical Services Section of the tube widely used in Beijing Guangguang equipment, the interface circuit is the focus of on-site maintenance, but also prone to failure of the site. 1 drive acquisition failure 1. If a microprocessor-driven relay does not act in the operation, the measurement
