全电子目标控制器通信单元设计方案研究

Design scheme of communication unit for fully electronic target controller

全电子计算机联锁系统逻辑部(简称:逻辑部)与全电子目标控制器间数据通信量大,对通信的安全性、可靠性和实时性等要求极高,为此,提出了基于二乘二取二架构的全电子目标控制器通信单元(简称:通信单元)设计方案。文章阐述了通信单元设计、软件功能,以及通信网络拓扑设计、通信协议设计、安全处理措施等,并进行了方案验证。验证结果表明,通信单元与逻辑部间的通信数据完整,通信质量稳定,满足设计要求。

The data communication volume between the logic department of the fully electronic computer interlocking system and the fully electronic target controller is large,and the requirements for communication security,reliability,and real-time are extremely high.Therefore,this paper proposed a design scheme for the communication unit of the fully electronic target controller based on the two by two out of two architecture.The paper elaborated on the design of communication units,software functions,as well as communication network topology design,communication protocol design,security measures,etc.,validated the proposed scheme.The verification results indicate that the communication data between the communication unit and the logic unit is complete,the communication quality is stable,and meets the design requirements.
