基于Zigbee的无线传感网络智能巡视监测系统设计

Design of Zigbee-based Wireless Sensor Network Intelligent Security Monitoring System

为了安防系统的监测实时性和可靠性,将无线技术应用到安防系统的设计中显得尤为重要。本文利用ZigBee无线模块、MQ2传感器、HC-SR501芯片等器件设计出了一个基于ZigBee网络实现的安防监测系统。文中对火灾及非法人员闯入的监测原理、电路和软件设计过程进行分析,给出了监测节点和协调器具体的实现方案。并以此为据,设计了系统的仿真电路。经测试,本设计可以实现对监测环境中火灾隐患及非法闯入信息的实时监测,并能实现联动报警。

In order to monitor the real-time and reliability of the security system,it is particularly important to apply wireless technology to the design of the security system.This article uses ZigBee wireless module,MQ2 sensor,HC-SR501 chip and other devices to design a security monitoring system based on ZigBee network.The paper analyzes the monitoring principle,circuit and software design process of fire and illegal intrusion,and gives the specific implementation plan of monitoring node and coordinator.Based on this,the simulation circuit of the system is designed.After testing,this design can realize real-time monitoring of fire hazards and illegal intrusion information in the monitoring environment,and can realize linkage alarm.
