重庆轨道交通2号线计算机联锁系统的发码设计

Coding Design in Computer Based Interlocking System for Chongqing Light Rail Transit Line 2

以重庆轨道交通2号线延伸段工程采用的TYJLIII型计算机联锁系统为研究对象,对该计算机联锁系统的联锁逻辑软件和操作显示软件进行发码特殊功能研究。提出了在不影响既有软件结构基础上新增发码模块的设计实现方法。测试验证结果表明,新增发码模块不影响既有计算机联锁系统软件结构,并满足设计需求。车站现场使用情况表明,采用这种发码设计方法的TYJL-III型计算机联锁系统能在保障既有计算机联锁系统可靠性和安全性前提下,更好地满足重庆轨道交通的工程设计和运营要求。

Taking the TYJL III computer based interlocking system adopted in the extension project of Chongqing light rail transit Line 2 as the research object,the special coding functions of the interlocking logic software,operation and display software for computer based interlocking system are studied,an implementation method by adding coding module without affecting the existing software structure is proposed.The test and verification results show that the developed coding module does not affect the software structure of the existing computer based interlocking system,and satisfies the design requirements at the same time.Field application indicates that the TYJL III computer based interlocking system with the coding design method can ensure the reliability and safety of the existing computer based interlocking system,also fulfill the requirements of the project design and operation of Chongqing light rail transit.
