基于ZigBee的环境参数远程无线监控系统设计

摘要

In view of remote-monitoring problem for indoor environmental parameters,a remote wireless-monitoring system based on ZigBee technology and mobile phone is proposed,which is used to realize the real-time data exchange.The sensor nodes collect the temperature,humidity,light intensity and smoke concentration,and transmit the data to the central coordinator by the ZigBee wireless network.The coordinator is connected with the WIFI module through the serial port,by which,the data is sent to the Internet.In addition,an Android mobile phone software is designed for the data acquisition,and issues instructions for adjusting parameters to complete the remote wireless monitoring task.As the test results show,the mobile phone is able to acquire and control the real-time environmental parameters in any place where the network is available.At the same time,the performance of nodes work stably and meet the need of long-term monitoring.%针对室内环境参数的远程监控问题,提出一种基于ZigBee技术与手机进行实时数据交换的远程无线监控系统:传感器节点采集环境中的温湿度、光强和烟雾浓度数据,通过ZigBee无线网络将数据传输到中心协调器;协调器与WIFI模块通过串口连接,将数据发送到互联网;另外,设计Android手机软件对监测数据进行获取,并发出对参数进行调节的指令,从而完成远程的无线监控任务;经过测试,通过手机可以在任何有网络的地方实时对环境参数进行采集和控制,且各节点性能稳定,满足长期监测的需求.
