摘要:
阐述了广州地铁7号线列车总风压力控制方式及控制逻辑,分析了总风压力低牵引封锁故障原因，指出了总风压力控制逻辑存在的缺陷。针对列车上电初期异常触发总风压力低导致牵引封锁的故障原因及总风压力控制逻辑存在的缺陷，提出了优化方案。优化方案可避免列车总风压力低牵引封锁故障的发生。
Abstracts:
The control method and logic of the vehicle total wind pressure on Guangzhou metro Line 7, together with the low traction and blockade faults are analyzed, defects in the control logic are pointed out. According to the causes for abnormal triggering of the total wind low pressure which leads to traction blockage fault, and the existing defects in the control logic at the initial stage of train power-on, an improved plan is proposed, aiming at avoiding the traction blockage caused by the total wind low pressure.
