Based On Zigbee Technology, Wireless Surveillance System Of Area Safety

Based fo ZigBee technology, the village intelligence safety monitoring system is realized by microprocessor S3C6410, embedded operating system as the core, through wireless sensor network transfer real_time data which acquisit by CC2430 node to clinet fuctions.Users can look monitor video and sensor data at anytime and anywhere by mobie phone or computer, because video and sensor data has been transported taking advantage of 3G network technology.This paper detail the overall hardware design of monitor video and how to control the TW2835 video chip in the kernel driver of Linux2.6. Introduction video capture, compression, storage, transmission and how to build the development platform of embedded linux operating system. This paper also Introduce functions of CC2430 which is ZigBee wireless network's point, design the structure of tree wireless based of ZigBee technology and write controling program of end point and gateway. Introduce the end point and gateway's work principle, how to build routing table and look up end point's address,or so design new sensor on the end point(CC2430).Mainly study as follows:1,Study video capture unit, design the TW2835 controller circuit,designing function make OSD display character, improve video processing and video quality2,Designing control 3G card circuit by microprocessor S3C6410, video surveillance data and sensor data of end point is transmitted through the 3G network.3,Design the node's promgram in the ZigBee wirelss network,with routing function.4,Design U disk and SD card storage solution...
