The invention relates to a method for resetting power-off latch faults of a motor train unit, and the method comprises the steps: determining the power-off latch faults and the numbers of the power-off latch faults through a power-off latch fault resetting unit additionally arranged on an HMI, and enabling a fault maintainer to determine the corresponding parts of each power-off latch fault one by one according to the power-off latch fault information displayed by the HMI, a reset instruction is sent through the latch reset module, after the CCU receives the reset instruction sent by the latch reset module, fault judgment and latch fault processing are carried out, countdown is carried out, if the vehicle is powered off within the countdown time, the corresponding fault is reset, and if the vehicle is not powered off within the countdown time, the fault cannot be reset even if the vehicle is powered off. The reset method is simple to operate, meets the requirements of power-off latch fault individuation and graded reset, can select power-off latch faults, and realizes reset of a single fault or multiple faults.
本发明涉及一种动车组断电锁存故障的复位方法,该复位方法通过HMI增设的断电锁存故障复位单元确定断电锁存故障及其编号,故障维修人员根据HMI显示的断电锁存故障信息逐一确定每个断电锁存故障的相应部件,通过锁存复位模块发送复位指令,CCU接收到锁存复位模块发出的复位指令后,进行故障的判断和锁存故障处理,并进行倒计时,若倒计时时间内车辆断电,则相应的故障会被复位,若倒计时时间内车辆未断电,则即使再断电该故障也不会被复位。该复位方法操作简单,满足断电锁存故障个性化以及分级复位的需求,并且可对断电锁存故障进行选择,实现单个故障或多个故障的复位。
