The Design And Research Of Community Security System Based On ZigBee

Community security system based on IOT achieves real-time monitoring of all targets insecurity monitoring field and provides the real-time display monitor area sensor data informationand alarm prompt In the PC software.This paper takes the development of ZigBee as an opportunity to research a kind ofintelligent security monitoring system design idea and the realization method. It has analyzed thetechnical structure of the security system and developed the equipment of the security system.This paper introduces the thesis of ZigBee characteristics and application field, and provides adetailed introduction to the main function of the physical layer, MAC layer, network layer andapplication layer of ZigBee standard and particularly described the ZigBee standard definition ofrandom address distribution mechanism and routing algorithm. This paper implements a networkintelligent security monitoring system, it includes the node hardware platform, network softwareplatform and PC display page.Hardware platform takes RF module CC2530as the core, and hasdesigned the terminal sensing nodes,routing nodes and the coordinator node. The development ofnetwork software platform takes the Z-Stack protocol Stack as the foundation to set up the wholenetwork from terminal node to coordinator node.The PC software take the IOT platformsoftware for secondary development to constitute the safety monitoring system demo page.The paper finally has tested the whole system and met the expected design requirements, ithas realized the self-organized routing function and high reliability. This paper looks forward tothe application development of the technology of IOT in the field of security in the end.
