摘 要
轨道电路以一段铁路线路的钢轨为导体构成的电路，用于自动、连续检测这段线路是否被机车车辆占用，也用于控制信号装置或转辙装置，以保证行车安全的设备。 整个轨道系统路网依适当距离区分成许多闭塞区间，各闭塞区间以轨道绝缘接头区隔，形成一独立轨道电路，各区间的起始点皆设有号志机(色灯式号志)，当列车进入闭塞区间后，轨道电路立即反应，并传达本区间已有列车通行，禁止其他列车进入的讯息至号志机，此时位于区间入口的号志机，立即显示险阻禁行的信息。
本论文主要阐述了轨道电路的硬件结构组成，轨道电路的作用，轨道电路的分类，轨道电路在铁路中的应用，工频交流连续式的轨道电路，道岔区段的轨道电路，轨道电路的极性交叉，钢轨绝缘节的设置，25HZ轨道电路，97型相敏轨道电路，移频轨道电路，轨道电路的基本工作状态和基本参数，轨道电路的维护和探讨。
通过本次设计，初步掌握了轨道电路的应用原理、故障处理步骤、方法、内容，技术改良的方向。

Track circuit a railway line to the rail of the circuit for a conductor, is used in the automaticand continuous detection this period of line is occupied by locomotive vehicles, but also tocontrol signal devices or to correct device, to ensure the safety of the equipment. The railsystem in accordance with the appropriate distance network divided into many block interval, each block interval to track the insulation joint segregation, form a separate track circuit, each interval is the starting point of a] light machine (color lamp type] light), when the trains into block after the interval, track circuit react instantly, and pass this interval for train routes, and by other trains into message to] light machine, located in the entrance of the interval at] light machine, show immediate dangers of drink-drivinginformation.
This thesis mainly describes the composition of the hardware of track circuit, the role of track circuit, the classification of track circuit, the application in railway track circuit, industrial frequency exchange successive track circuit, turnout section of track circuit, the polarity of the track circuit and cross section of the insulation rail set, 25 HZ track circuit, type 97 phase sensitive track circuit, frequency shift track circuit, the basic work of track circuit state and basic parameters, the maintenance of track circuit and the discussion.
Through this design, preliminary master track circuit application principle, fault handling procedures, methods, contents, the direction of improving technology.
