区间轨道电路历程及发展

History and Development of Section Track Circuit

轨道电路作为室外信号设备三大件之一,对保证列车安全高速运行有重要意义,可分为站内轨道电路和区间轨道电路。主要论述区间轨道电路,其主要作用是监督各闭塞分区空闲及占用状态,同时传递有关行车信息。随着国内铁路事业的高速发展,了解区间轨道电路的发展历程,分析其趋势,展望其未来发展方向,必将对铁路建设工作起到积极作用。

As one of the three outdoor signal devices,track circuit is of great signifi cance for ensuring safe and high-speed train operation.It can be divided into station track circuit and section track circuit.This paper mainly discusses the section track circuit,whose main function is to supervise the clear or occupied state of each block section,and at the same time to transmit the relevant traffi c information.With the high-speed development of China's railway,understanding the development process of section track circuit,analyzing its trend and looking forward to its future development direction will certainly play a positive role in China's railway construction.
