Abstract: In computer interlocking systems, the centralized control mode includes many problems such as centralized risks, higher project costs, and difficult tasks of system maintenance. In order to promote the reliability, security, and flexibility of system, by introducing the concept of Field Controller（FC） which is combined with other techniques such as the distributed control and intelligent control, a novel distributed all electronic computer interlocking system is presented and described. The reliability performance evaluation framework for the input control function is constructed subsequently. The quantitative analysis and simulation are also done for this reliability architecture. The results from simulation analysis show that this system can provide a good system reliability in 100000 hours. It also proves that the design of the electronic computers interlocking system is reasonable and efficient.

摘要： 以联锁机为核心的集中控制方式是目前计算机联锁系统的主流。但其存在风险集中、工程造价较高、系统维护困难等问题。为了进一步提高系统的可靠性、安全性、灵活性，引入区域控制（Field Controller）的概念，将其与分布式控制、智能控制等技术相结合，提出了一种新型的分布式全电子计算机联锁系统结构。以实现进路控制功能为依据建立系统可靠性框图，对其进行定量的可靠性分析及仿真，仿真结果表明系统可保持100 000小时可靠运行。以上分析可知：该分布式全电子计算机联锁系统的结构设计合理。
