摘要
动车所咽喉区调车作业频繁,冒进信号的安全防范至关重要。受站场站形布置影响,分散式调车防护装置与调车信号机距离不满足最不利条件下18 m的要求,限制了调车防护系统发挥运输安全中“技防”措施的重要效能。相关规范规定分散式调车防护系统的每套调车防护装置可带载两套报文传输模块,一定程度上提升了站场条件限制下多方向调车进路的安全防护。本文以按现行规范已实施该系统的某动车所为例,结合咽喉区道岔紧凑布置情况,分别从系统构成、系统适用场景、岔区应答器安装、系统功能设计、报文编制等方面,对多进路防护的分散式调车防护系统设计进行分析,可对不同类型的动车所调车防护系统工程设计提供参考。
Shunting operations in the throat area of EMU depot are frequent,and the safety precautions against overrunning signals are crucial.Affected by the layout of the station yard,the distance between the decentralized shunting protection devices and shunting signals can not meet the requirement of 18 m under the most unfavorable condition,which limits the crucial role of the shunting protection system as a“technical prevention”measure in ensuring transportation safety.According to the specification,each set of decentralized shunting protection devices can carry two sets of message transmission modules,enhancing the safety protection for multi-directional shunting routes under limited station yard conditions to some extent.Taking an EMU depot where the system has been implemented according to current specifications as an example,and considering the compact arrangement of switches in the throat area,this paper analyzed the design of a decentralized shunting protection system with multi-route protection from aspects such as system composition,applicable scenarios of the system,installation of transponders in the switch area,system function design,and message formulation.It can serve as a reference for the engineering design of shunting protection systems in various types of EMU depots.
