摘要
在分析中小运量轨道交通自身建设特点的基础上,对全电子联锁和传统计算机联锁进行比较,剖析了全电子联锁系统的系统结构,重点介绍了逻辑运算层的二乘二取二硬件结构和执行表示层硬件组成,列举了为提高全电子执行单元的安全性、可靠性在软件、硬件方面所采取的防护措施。证明全电子联锁系统在维护性、扩展性、冗余性方面比计算机联锁更有优势,具有设备占地面积小,总投资低,施工简单的特点,更适合于中小运量轨道交通建设工程的实际需求。
In this paper, based on the analysis of the characteristics of the construction of small and medium volume rail transit, the author firstly compares the all-electronic interlock with the traditional computer interlock. The system structure of the all-electronic interlock system is analyzed, the hardware structure of the logic operation layer and the hardware composition of the execution presentation layer are mainly introduced, and the protective measures in software and hardware are listed to improve the security and reliability of the all-electronic execution unit. It is proved that the all-electronic interlock system has more advantages than the computer interlock in terms of maintainability, expansibility and redundancy. It has the characteristics of small equipment floor space, low total investment and simple construction, and it is more suitable for the actual demand of small and medium volume rail transit construction project.
