Design And Realization Of Wireless Remote Image Monitoring System

Monitoring system is one of the key equipments for the agriculture, transportation,environment monitor and national defenses. Nowadays the lineate monitor systemsoccupy the monitor system market, but the applications are limited by the physicaldisadvantages in some difficult situations, such as the monitors'points distributebroadly. The wireless monitor systems are the just resolutions. With the fastdevelopment of the computer and communication technology, the wireless monitorsystem combining the embedded system technology, wireless communicationtechnology and internet technology can be realized. These monitor systems challengethe development of the embedded system technology. The multimedia data transmittingneeds improvements of the wireless communication technology.The paper presents a kind of wireless monitor system based on the GSM/GPRSnetwork after the analysis of lineate monitor systems. It gives the details of the systemdesign and development of the sample system. The result of the experiments illustratesthat the system is able to transmit the images from the point to the server, realizing thesystem function.In this paper, the author gave the details for why and how to choose the CPU andthe other peripheral equipments. After choosing the hardware, the author mentioned thesoftware platform and the cross-compile method. Also, the author realized the replantof the embedded Linux system (uClinux) to the ColdFire5272 platform. Further more,the author emphasized the realization of the application software, such as the mainprogram based on kinds of programming language, the drivers for the W99200F imagecard and the communication of the system based on the GSM/GPRS network. Finallythe author did the experiments with the monitor system by two modes (FTP mode andsocket mode) and gave different results of these experiments. The author analyzed theresults, presenting the advantage and the disadvantage of them. In the end of the paperthe author described how to improve the system and showed the foreground of thewireless monitor system.
