Research And Design Of Security System Based On ZigBee Wireless Intelligent Network

With the rapid development and people’s living standards in the market economy gradually improved, especially in the big city, liquidity and a sharp increase in foreign population, makes people start to the family security demand is more and more high, the home security system will make people’s life more convenient and safe. The traditional family security system because of complicated wiring, the system stability is not high, but also prone to some false positives, and even influence the indoor beautiful. So people eager to have a high degree of integration, the corresponding speed, intelligent and anytime security system of wireless intelligent network monitoring. Developed in the age of the Internet, the traditional security system to change the security system of wireless intelligent network has become a.At present, many families of the security system have adopted the main controller design pattern with a short distance wireless communication technology. Of course, the short distance wireless communication technology will get extensive application in home network. This thesis chooses based on ZigBee communication protocol of wireless communication technology as the system of wireless network set up, select the ARM embedded development board do as the core controller, select the Linux operating system as the design of the main control system, using GSM/GPRS SMS remote alarm mode, research and design the ZigBee wireless intelligent network home security alarm system based on.In this paper, the design of the system is detector node bindings to ZigBee terminal equipment, by many ZigBee module for wireless network wireless home network nodes, front-end data acquisition. ZigBee coordination device node will collect the data information is sent a ARM11 development board, arm development board through the data analysis judgment alarm information, by judging whether there is abnormal, and to control the GPRS SMS transceiver module to send text messages to inform, complete alarm function.This paper mainly from two aspects of hardware and software of ZigBee intelligent network security system were design and research. Through the circuit principle diagram design, fully grasp the working principle of each module and give full play to its characteristics. The system built embedded software platform, using the Linux operating system platform, achieve a high reliability, simple and convenient operation, low cost, stable, safe home security system, with good prospects for the application.
