摘　　要：基于.NET开发环境,开发了一套对电厂DCS系统每秒输出万级实时数据的接口软件系统。该系统在M/S架构下,使用Modbus TCP通信协议,基于MySQL结合JSON格式存储通信配置,利用AJAX技术和Layui前端框架实现了用户对接口点表的灵活配置。用C#的Winform框架实现了可视化监控界面,开关量装箱拆箱技术大幅提高了硬件使用效率,动态编译技术实现了对输出信号的二次加工,有效提高了后台程序运行速度和程序可靠性。Based on.NET development environment,a set of interface software system is developed to output ten thousand level real-time data per second to DCS of power plant.The system based on Modbus TCP protocol under the M/S architecture,which is based on MySQL and JSON format stored communication configuration,using AJAX technology and Layui front-end framework implements the flexible configuration of the point information.Using C#Winform framework implements visualization monitoring interface.The boxing and unboxing of discrete signals greatly increased the efficiency of the hardware.The use of the dynamic compiling technology to achieve the secondary processing of the data,effectively improves running speed and reliability of the background program.
