随着铁路和轨道交通的快速发展,列车运行密度越来越高,行车间隔越来越短,为确保列车运行安全,必须对前后列车之间的最小停车距离进行安全分析,建立最不利情况下停车距离的安全数学模型,车载信号系统据此安全模型以确保任何情况下前后列车间的间隔都大于该最小安全间隔;同时据此对线路的闭塞设计进行安全仿真评估,满足最不利情况下停车距离。
With the rapid development of railways and rail transit, the running density of trains is getting higher and higher, and the driving intervals are shorter and shorter. In order to ensure the safety of trains, the minimum stopping distances between the trains must be analyzed safely and the most unfavorable conditions Parking distance of the safety mathematical model, the vehicle signal system under this safety model to ensure that any case of the interval between the front and rear of the train are greater than the minimum safety clearance; at the same time accordingly, the line of the occlusion design of safety simulation assessment to meet the most adverse circumstances parking distance.
