四点检查法正常解锁的探讨

Investigation of Four-point Check for Normal Release

本文目的是实现列车进路采用四点检查法正常解锁,而调车进路仍采用三点检查法正常解锁。分析了解决四点检查法的关键是区分列车运行方向,并详细描述了通过增加运行方向继电器电路、修改道岔锁闭继电器电路来实现四点检查法正常解锁。

This paper was aimed to realize normal release of train operation route through four-point check approach and normal release of shunting route through three-point check approach. This paper analyze the key of four-point-check release is to distinguish train running direction and describes how to realize four - point - check release by adding the XTDJ/STDJ circuit and modifying the SJ circuit.
