Existing Railway

With the development of high-speed railway , the traditional artificial supervision can not meet the existing railway security operation .

随着高速铁路的发展，传统的通过人工检测过往车辆与车站安全信息的方法己不能满足现有铁路安全运行的需要。

To improve the acknowledgement of existing railway intelligent signal power supply , the development , characteristics , types , and composition of intelligent signal power supply are discussed .

主要介绍智能信号电源屏切换系统的发展、特点、类型和组成，达到对现有铁路智能信号电源提高认识的目的。
