Research And Implementation Of Remote Measurement And Control System Based On Embedded Web Server

Since the mid-twentieth century, with the rapid development of information technology, people?s attention on the remote control and remote measurement system continues to increase. More and more people are concerning about remote control and remote measurement system and doing depth study. Currently, remote monitoring and control system at the rapid development of integrated circuits, network communications, multimedia, and other technology, is toward miniaturization, intelligence and network direction. Traditional remote monitoring and control system is generally based on C/S(Client/Server client-server architecture) framework, but C/ S itself has many problems.Based on B/S(Browser/Server) architecture Web service becomes more and more popular and is widely applied to various field fo r its low cost, easy upgrades and maintenance.In this paper, Based on B/S architecture,we design and implement an embedded web remote monitoring system. Embedded Web server system is responsible for storing the data by sensors and transmit it to remo tive clients. Remote clients not only can view the real-time data and the historical data, but also control the system only with browsers.In this paper, we give the overall hardware and software design of the system, choosing mini2440 development board with a samsung S3C2440 A processor as hardware and embeded Linux as operation system. Modify and transplant u-boot-2010.03 according to mini2440 development board, and analyze the process of u-boot in detail. We do depth research in compiling and transplan ting linux 2.6.32 kernel and embedded web server Boa, focuse on CGI progarm development with SQLite embedded database and Linux char device driver, in the end, we make web pages as interactive interface between humans and the system, realize the remote measurement and control system. The system is designed by modules with high reliability and easy upgrade and maintenance.
