铁路信号是保证铁路运输基本设备。对铁路网上各种行车的设备状况、信息传输、调度指令控制起着重要的作用。目前,人们对铁路信号有不同的理解。有人把铁路信号广义理解为:保证铁路行车安全的技术和设备;有人狭义理解为:用于向行车人员指示行车条件的符号;有人则认为:铁路信号是铁路上信号显示、联锁、闭塞设备的总称。铁路为实现高速、高密度和重载运输的需要,积极引进采用新技术,大幅度提高了现代化通信信号设备的装备水平,新型技术系统不断涌现。本文通过对铁路信号存在问题的分析,提出了解决问题的对策,指出了我国铁路信息的发展方向。
Railway signal is to ensure the basic equipment of railway transportation. It plays an important role in controlling the equipment status, information transmission and dispatching instructions of all kinds of driving on the railway network. At present, people have different understandings of railway signals. Some people think that the railway signal is broadly understood as: technology and equipment to ensure the safety of railway traffic; some people understand it in a narrow sense: it is used to indicate the driving conditions to traffic signs; some people think: railway signals are signals on the railway, interlocking and blocking equipment The general term. In order to meet the needs of high-speed, high-density and heavy-haul transportation, the railway actively introduces and adopts new technologies and greatly improves the equipment level of modern communications signal equipment. New technical systems are emerging. In this paper, through the analysis of the existing problems of railway signals, the countermeasures to solve the problems are put forward, and the development direction of railway information in our country is pointed out.
