The invention provides an automatic opening speed protection method, system and equipment for urban rail transit, and the method comprises the steps: obtaining first front information through an active transponder, checking the credibility of an obstacle monitoring unit based on the first front information, and determining the normal working state of the obstacle monitoring unit through the credibility of the obstacle monitoring unit; the obstacle monitoring unit obtains second front information in a normal working state; and determining an automatic opening speed triggering condition according to the first front information and the second front information, calculating a real-time opening speed according to the second front information, and controlling the train to trigger the automatic opening speed according to the automatic opening speed triggering condition. Therefore, the train operation can be protected according to the front signal lamp and obstacle information, the operation risk of a driver is reduced, and the driving safety is improved. According to the method, the scheme of predicting the opening speed when the transponder is lost in a point mode is optimized, a higher opening speed limit can be given on the premise of ensuring safety, and the operation efficiency is improved.
本发明提供一种城市轨道交通自动开口速度防护方法、系统及设备,通过有源应答器获取第一前方信息,基于所述第一前方信息校核障碍物监测单元可信度,通过障碍物监测单元可信度确定障碍物监测单元正常工作状态;所述障碍物监测单元在正常工作状态下获取第二前方信息;根据第一前方信息和第二前方信息确定自动开口速度触发条件,根据第二前方信息计算实时开口速度,并根据自动开口速度触发条件控制列车触发自动开口速度。由此可知,能够根据前方信号灯及障碍物信息防护列车运行,降低减少司机的操作风险,提升行车安全性。本发明优化了点式模式下预告应答器丢失时的开口速度方案,在保证安全的前提下可以给出更高的开口速度限速,提高运行效率。
