摘要联锁是利用相应的技术手段，根据实际情况，在信号机、道岔和进路三者之间建立起相辅相成、紧密关联的关系。其主要目的是为了保障列车行驶的安全性。

本文首先以车站联锁系统的原理为基础，根据实际案例需求，给出6502电气集中联锁的设计方案，按照车站站场图以及联锁表的绘制规则，绘制包括所有道岔、信号机、进路在内的联锁表，并指出6502电气集中联锁系统现阶段存在的缺点。然后介绍计算机联锁系统硬件层次结构。通过比较目前现有的三种新型计算机联锁结构，选出最合适的计算机联锁系统。最后，论文对软件进行设计，根据联锁的功能，设计出对应的流程图。81144

The Design of the Station Interlocking System

Abstract Railway Stations Interlocking System is the interlocking system which realizes restrict and operation sequence between signal, turnout and route by technical method。 With the continuous expansion of the scale of the railway network and the continuous speed of the railway, the development of more advanced station interlocking system has become an inevitable trend。

This article is based on the principle of the interlocking system of the station。 According to the needs of the actual case, it gives the design scheme of 6502 electrical concentrated interlocking, and points out the demerits of the 6502 electric interlocking system existing at the present stage。 In accordance with the station yard diagram and the drawing rules of the interlocking table, I draw the interlocking table including all switches, signal machines, routes, and so on。 And then the hardware layer structure of computer interlocking system is introduced。 By comparing the advantages and disadvantages of hot-standby structure, two-out-of-three structure and Double duplicated modular redundancy structure, this paper selects the most suitable computer interlocking system。 At last, the paper designs the software according to the function of interlocking, and designs the corresponding flow chart。

This paper has 19 figures, 2 tables, 46 references。
