摘要:
地铁车辆辅助系统充电机模块为全车提供低压供电，为确保其在受干扰后能够迅速恢复至工作状态，需在控制软件中加入故障复位机制。以苏州轨道交通4号线车辆辅助系统充电机模块为研究对象，分析了充电机驱动板直通故障原因，提出了在车辆辅助系统控制软件中增加故障复位机制的解决对策。基于可靠性试验，对该故障复位机制进行了优化。试验验证表明，优化后的故障复位机制可有效解决充电机驱动板直通故障。
Abstracts:
Metro vehicle auxiliary system charger module provides low-voltage power supply for the whole vehicle. To ensure that the vehicle can quickly return to the working state after being disturbed, fault reset mechanism needs to be added to the control software. Taking the auxiliary system of Suzhou Rail Transit Line 4 as the object, the reason of charger driver board straight through fault is analyzed, and the solution of adding fault reset mechanism in vehicle auxiliary system control software is proposed. Based on reliability experiment, optimization of fault reset mechanism is carried out. The experiment proves that the optimized fault reset mechanism can solve the driver board straight through problem effectively.
