摘 要
计算机联锁系统是继继电集中系统的另一种联锁系统，它可以保证工作可靠，确保行车安全，符合“故障—安全”原则。计算机联锁是当前最先进的联锁，我国的计算机联锁就是从继电集中过渡过来的。
本次设计为电化区段兰成线34号站下行咽喉计算机联锁工程设计。设计的主要内容包括：34号站下行咽喉车站信号平面布置图，它可以直观的反映出信号机、道岔、警冲标等的布置情况以及它们的编号与位置的计算。下行咽喉联锁表，它主要包括了进路方向、按钮、道岔、敌对信号以及轨道区段的选择与确定等。双线轨道电路布置图，它主要完成的是轨道电路极性交叉、扼流变压器、送受电端的布置。电缆网络图和径路图，主要是电缆的合理敷设、电缆长度的计算、芯数的计算等，它是施工挖沟的主要依据。计算机联锁系统结构图，可以反映出所采用的双机热备系统的硬件构成以及它的工作原理。组合排列表，反映了信号柜、轨道柜、道岔柜的排列情况与组成。组合类型表，包含了各种组合所包含的继电器名称和类型。室内设备平面布置图包括了电源室、控制台室、防雷分线室等室内各种设备的布置。工程数量统计表，统计的是34号站下行咽喉所需要的所有电缆线、信号机、盒子、柜子、道岔、轨道、继电器等的数量。
