计轴叠加同时解决分路不良及漏泄大方法探讨

Measures of Solving Problems of Poor Track Circuit Shunting and Large Railway Bed Leakage by Overlapping Axle Counter Circuit and Existing Track Circuit

简要介绍计轴轨道电路从制式上解决对行车组织造成影响的轨道电路分路不良和道床漏泄大的原理,说明单独使用计轴设备时,存在不具备检查断轨功能、电码化区段需要专设发码通道且易误触发等方面问题,对计轴轨道电路和既有轨道电路叠加方式进行讨论,提出解决轨道电路分路不良及漏泄大问题的具体方案。

This paper briefly introduces the principles of solving the poor track circuit shunting and the large railway bed leakage affecting the organization of train operation by the axle counter circuit systematically, describes the issues such as there is no function to check broken rail only by the axle counting device, the coding section should be equipped with a dedicated code sending channel to avoid incorrect triggering, and discusses the overlap method between axle counter circuit and existing track circuit. It puts forward the specific proposals to simultaneously solve the problems of poor track circuit shunting and large railway bed leakage.
