基于Modbus TCP的专用集中监控系统通信测试装置设计

Design of Communication Test Equipment for Centralized Control System Based on Modbus TCP

阐述专用工艺集中监控系统通信测试装置设计,它采用工业以太网中的Modbus TCP通信协议,建立Client/Server架构形式的工艺数据仿真平台,基于数据仿真服务端和数据下发服务端,实现测试装置和集中监控系统之间的通信,并采用MySQL数据库生成固定数据源,保证数据仿真的准确性。

This paper describes the design of the communication test device for the dedicated centralized process monitoring system. It uses the Modbus TCP communication protocol in Industrial Ethernet to establish a process data simulation platform in the form of Client/Server architecture. Based on the data simulation server and the data distribution server, it realizes the communication between the test device and the centralized monitoring system, and uses MySQL database to generate a fixed data source to ensure the accuracy of the data simulation.
