摘　　要：针对热电厂调控系统中对采集数据信息的准确性、实时性、安全性等特殊设计要求,结合电子设备特性与特殊工作环境,该文设计了基于自定义协议的维护通信总线M-BUS。通过自定义格式实现各通信接口模块的数据实时稳定传输,并采用485总线数据流模式控制。该总线具有准确、可靠、通用等优势,为热电厂调控系统的标准化和通用性及控制管理机制提供了一种解决方案。Aiming at the special design requirements for the accuracy,real-time and security of the collected data in the control system of thermal power plants,combined with the characteristics of electronic equipment and special working environment,this article designes a maintenance communication bus M-BUS based on a custom protocol. Through the custom format,the real-time and stable transmission of data of each communication interface module is achieved,and the data flow mode control of the 485 bus is adopted. The bus has the advantages of accuracy,reliability,and universality,providing a solution for the standardization,versatility and control management mechanism of the thermal power plant control system.
