区间综合监控系统在单线双方向自动闭塞线路的应用

Application of Comprehensive Section Monitoring System in Single-track Line Under Automatic Block with Bi-direction Train Running

目前在采用继电编码的普速线路上,只能通过增加继电电路,实现对区间通过信号机显示和轨道电路发码正确性的安全防护.不仅需要增加大量继电器,而且配线复杂,施工难度较大.因此,本文提出采用基于安全计算机技术的区间综合监控系统,针对单线双方向自动闭塞线路增加区间占用逻辑检查功能.

On ordinary railway line using relay coding,the safety protection for the correctness of the signal display and the track circuit can be realized only by adding relay circuit.However,a large number of relays and relay combination circuits would be added,which leads to complicated wiring and the difficulties in construction.Therefore,a comprehensive section monitoring system based on secure computer technology is proposed to realize section occupation logic check function to a single-track line under automatic block with bi-direction train running.
