The invention discloses a method for designing the unlocking time of a protection section in a point backup mode, and relates to the technical field of urban rail transit signal systems, the designed unlocking time of the protection section is managed by a ground interlocking system, and the time required by the protection section from unlocking timing starting to unlocking completion is a set value. The set value is larger than or equal to the unlocking time safety value and smaller than or equal to the unlocking time efficiency value. Wherein the unlocking time efficiency value is the sum of the running time, the station dwell time and the turn-back operation waiting time of the train in the route; the unlocking time safety value is the sum of the response time of the ground interlocking subsystem, the variable effective time of the train automatic protection subsystem and the emergency braking stop time. Therefore, the set value is related to the running time, the station dwell time and the turn-back operation waiting time of the train in the route, the response time of the ground interlocking subsystem, the variable effective time of the automatic protection subsystem of the train and the emergency braking stopping time, and the problems of safety risks, turn-back capacity and the like are fully considered.

    本发明公开了一种点式后备模式下保护区段解锁时间设计方法,涉及城市轨道交通信号系统技术领域,其设计的保护区段的解锁时间由地面联锁系统管理,且保护区段从开始解锁计时到解锁完成所需的时间为设定值,设定值大于等于解锁时间安全值,小于等于解锁时间效率值。其中,解锁时间效率值为列车在进路内的运行时间、停站时间、折返作业等待时间之和;解锁时间安全值为地面联锁子系统响应时间、列车自动防护子系统变量有效时间和紧急制动停车时间之和。因此设定值与列车在进路内的运行时间、停站时间、折返作业等待时间,以及地面联锁子系统响应时间、列车自动防护子系统变量有效时间和紧急制动停车时间有关,充分考虑了安全风险、折返能力等问题。
