厂矿企业铁路道口安全报警系统的运用与改进

Application and Modification of Alarming System of Railway Crossing of Industrial and Mining Enterprises

本文介绍了在燕山石化两个铁路道口的改造施工中,基于DX03道口信号控制原理,对报警通知和通知到达等电路进行的改进。通过对既有轨道电路和DK·SWK30(40)型开路式道口控制器的组合应用,分别实现通知、到达条件,控制道口电路。

This paper introduces the modification of alert-notice and arrival-notice circuits based on the DX03 railway crossing signal control principle in the reconstruction of two railway crossings in Yanshan Petrochemical Corporation. This reconstruction realizes respective notice and arrival conditions to control crossing circuit by way of combination of the existing track circuit and the electric circuit of the Alertnotice and the arrival-notice.
