步骤d)中两个安全稳定控制装置均按正常方式投入压板时，检测在两个安全稳定控制装置上交互的信息是否一致，依次检测通道压板退出、过载功能压板退出、总功能压板退出及物理通道收发断开情况下检测在两个安全稳定控制装置上交互的信息。In step d), when the two safety and stability control devices are put into the pressure plate in the normal way, check whether the information exchanged on the two safety and stability control devices is consistent, and sequentially detect the exit of the channel pressure plate, the exit of the overload function pressure plate, the exit of the total function pressure plate, and the physical function. Detects the information exchanged on the two security and stability control devices when the channel is disconnected.
