铁路区间闭塞技术的发展与研究

Development and Study of Raiway Section Block Technology

区间闭塞技术是铁路行车安全保障和运输效率提高的重要手段,世界铁路从运营开始就诞生了行车闭塞法,对区间列车运行线路进行封闭,不准许其他列车驶入,防止列车相撞。区间闭塞由人工闭塞、半自动闭塞,逐步发展到自动闭塞、移动闭塞。区间闭塞研究不仅是保障行车安全,还是制约运输效率的最关键基础设备,改进区间闭塞制式是提升运输效率的有效措施。本文在回顾区间闭塞发展历程的基础上,对区间闭塞未来发展进行了展望,对各种闭塞制式的运输能力进行了对比分析。

Section block technology is an important means to ensure the safety of railway traffic and to enhance the efficiency of transportation.From the beginning of the operation of railway in the world,the method of traffic block was born,which closed the running line of a train and did not allow other trains to enter the line so as to prevent the trains from colliding.Section block evolves gradually from manual block,semi-automatic block,automatic block to moving block.However,the research on section block is not only a meanns for safety assurance but also the most critical infrastructure equipment that would restrict the efficiency of transportation.So,to improve section block system is an effective measure to improve the efficiency of transportation.On the basis of reviewing the development process of section block,we prospect the future development of section block and make a comparative analysis on the carry capability of various block systems.
