列车自动驾驶(ATO)季节性调节方案探讨

Discussion on Seasonal Regulation Scheme of Automatic Train Operation

ATO目前已广泛应用到地铁列车的车载信号系统,提高地铁列车的运行效率,而列车的制动性能对ATO控制精准停车有比较大的影响。列车制动性能,特别是气制动性能可能存在一定的不稳定性,对ATO发出制动指令的响应会出现较大的偏差,其中一个较重要因素就是季节以及气温的影响。探讨针对列车制动季节性变化进行相应的优化、增加自动驾驶系统的自适应能力的方法。结合制动性能变化,对每一个制动变化时段做出单独的制动驾驶控制策略组,在相应的时间段(或其他设定条件)自动切换、调节,使在不同的列车制动性能下,自动驾驶系统均能实现精准停靠站台,提高乘客上下车效率。

Automatic Train Operation(ATO)has been widely applied to the onboard signaling system of subway trains,which improves the operation effi ciency of subway trains.The braking performance of the train has a greater impact on the precise stop controlled by ATO.The train braking performance,especially the air braking performance,may be unstable to a certain extent,and the response to ATO's braking command may have a large deviation.One of the more important factors is the infl uence of season and temperature.This paper explores the method of optimizing the seasonal deviation of train braking and adding the adaptive ability of ATO system.In combination with the braking performance change of a certain line,a separate braking control strategy group is made for each braking change period,and switch and adjust is conducted automatically in the corresponding time period(or other setting conditions),so that under diff erent train braking performance,ATO system can achieve precise stopping at the platform and improve the effi ciency of passengers getting on and off.
