Research On Wireless Monitor Systems Based On UClinux & WEB

With the development of industrial control,some application field is facing higher and newer requirement.These applications have the feature of covering a wide range and distribution control point or the object is always moving.So how to realize the monitoring and controlling them efficiently and economically is a new subject submitted to us. With the development of the long-range transmission technology of the data, wireless communication is adopted extensively and gradually, among them the data business of grouping based on GPRS network has got the extensive application. In this thesis, we integrate advanced technologies such as mobile communication , Internet, embedded technologies to realize multi-point control based on mobile platform.All these totally breaks the limit of district and the traditional net framework and provides a che(?)p,reliable solution.The thesis enters with the research of the current state of remote control system. In the thesis,we combine the feature of remote control system ,SMS and GPRS and put forward the design of remote control system based on mobile platform. This thesis highlights hardware system design based on S3C44B0X processor, including S3C44B0X smallest system design and GPRS module interface -design. It also analyzed the function and the transplant method of bootloader, focused on uClinux core structure, the step of allocation and tailoring uClinux core,the compilation method of the uClinux application procedure.This article has also reserched the GPRS module function with emphasis, how to realize short news receiving and dispatching using AT command of GPRS module. Then we introduce embedded WEB server, build a Boa WEB server and complete dynamic WEB technology.The GPRS technology has the remarkable advantages such as strong real-time, broad reading scope, quick transmission speed, low communication cost, big system capacity, and so on.It utilizes the direct connection between GPRS network and Internet, setting a server in Internet, which takes charge of the transfer of the communication of the master station and the terminal units. This new system, which is characterized by higher speed and great data throughput, well satisfies the demands for reliability and real time of the data communication in remote control system.This system has the advantages of short connection time, high real-time performance and low engineering expense, thus it is more suitable for some atrocious environments of mountainous and swamp area.
