1、 - I -摘 要计算机联锁是采用是现代计算机技术取代继电电路实现的一种新型车站信号联锁设备，同继电设备相比不仅性能价格比高、功能强，而且具有更高的可靠性和安全性，符合“故障安全”的原则，实现联锁的基本功能。计算机联锁可以完成列车进路建立、锁闭、解锁、道岔控制、信号机控制、轨道电路和信号设备状态的监督，实现铁路系统特殊的联锁功能，确保列车进路正确和列车运行的安全。本设计选用的站场为一个虚拟的 14 号车站上行咽喉计算机联锁工程设计，内容包括：信号平面布置图，该图能正确反映计算机联锁系统室外主要设备的布置情况，主要完成道岔、警冲标、信号机坐标的计算并确定其位置；双线轨道电路图，站内采用25Hz
2、轨道电路，完成轨道电路的极性配置、扼流变压器的设置以及送受电端的布置；联锁表，包括基本进路的选择、敌对信号的确定、轨道区段侵限检查等；电缆径路和电缆网络图，根据公式计算电缆长度，选择电缆径路以及计算所需芯线数；系统结构图，可以了解所采用的的系统硬件构成以及其工作原理；室内布置图，即室内各种设备的布置情况；组合类型表和组合排列表可以看出各种组合所包括的继电器名称和类型以及各种组合在组合架上的排列。关键词：计算机联锁；轨道电路；信号机；联锁表关键词：计算机联锁；轨道电路；信号机；联锁表- II -AbstractComputer interlocking system is used the mo
3、dern computer technology replacing relay circuit implementation of a new station signal interlocking equipment, compared with relay equipment Performance/Cost is not only high, the function is strong, and has higher reliability and safety, comply with the principle of “fail-safe“. The basic function
4、 of the interlocking is to create, lock, release, switch control, signal control the completion of the train route, to complete the supervision of the state of track circuits and signaling equipment, and use special interlocking rail system to ensure the correct of the train route and the safety of
5、the train operation. The design selected for up throat of station No.14 computer interlocking engineering, the design elements includes: The signal layout map, which accurately reflect the setting circs of the main outdoor facilities, the main task to complete the switch, fouling post and the calcul
