Research On Graphics Configuration Software For Web-Based Measurement And Control System

With the rapid development of configuration software technology,its application increases widespreadly in the field of measurement and control.Currently,B/S-based embedded configuration software is needed in the field of measurement and control,but there is no studying of this configuration software.For this purpose,a graphics configuration software for web-based measurement and control system is designed in this thesis.Then mobile phones,computers and other networked terminals can be used to view the configuration operating interface and control on-site equipments while staff in this system design configuration for measurement and control system by using this software.The main work of this thesis is as follows:(1)Through the studying of the status about the configuration software development at home and abroad,system architecture and design of configuration software for web-based measurement and control system are proposed,on the same time the key technologies used in this design are discussed;(2)GUI subsystem of the software has been anlaysed and designed.Object-oriented thinking is used to develop programe and a variety of operating and user interface.On the other hand,configuration files for development and runtime environment have been designed and analysed then FTP client is designed to upload configuration files;(3)Web server subsystem of the software has been designed.First,the web server subsystem is built on the embedded development platform using S3C2440 as its core to establish the operating environment of the sofeware.Then the programes for the server are designed including data process,transmission and interaction to achieve the aim of running configuration software on the embedded platform;(4)Web client programe has been developed.Three parts are included:configuration webpage,dynamic interaction of configuration interface using network scripts,design of configuration controls to display and transmit data in webpage.All the parts are designed to realize the aim of running configuration interface on the client browser;In this thesis,the development of the GUI subsystem,web server subsystem,and the web client programe of the software are elaborated in detail,while the software has been developed successfully.This software is applied in the simulation tank control system.Then configuration files are uploaded to embedded platform.At last,the aim of configuration monitoring of the controlled system on the browser has been realized.The whole subject has achieved the expected effect.
