Design Of Industrial Control Configuration Software Based On Domestic Platform

The industrial control configuration software is a software platform of the monitoring layer in the industrial control system.It is specially used for data acquisition and process control.It is usually composed of multiple functional modules with independent functions.The advantage is not only to shorten the development cycle of the target application,but also to be highly reliable and easy to expand.However,in view of the fact that the mature commercial configuration software currently running on the market basically runs on the Windows operating system and the state has autonomously controllable demand for information technology.This paper chooses to complete the industrial control configuration software based on Qt framework on domestic platform,focusing on the design and implementation of subsystems such as graphic configuration and communication configuration.This paper summarizes the functions that configuration software needs to meet from the user's point of view.The modularization method is used to design the overall structure of the configuration software system.Based on the idea of object-oriented design,the graphic element class is abstracted,the graphic configuration subsystem is designed with Qt graphics view framework,and the concrete design idea and key implementation code are given.The connection between serial communication and network communication can be established by using the serial port class and Qt Network module provided by Qt,and the Modbus communication protocol class is preliminarily designed on this basis.The graphics configuration subsystem of the configuration software can provide a largenumber of basic vector primitives,dynamic primitives and library functions.It is easy to operate and flexible.It enables users to edit a good man-machine interface.At the same time,it achieves the animation connection effect of primitives and ensures the dynamic connection between I/O variables and monitoring pictures.The communication module realizes the serial connection and network between monitoring host and monitoring equipment,and ensures point-to-point communication or data interaction around the server.Finally,an example is given to demonstrate the practicability of the system.
