摘要
针对传统室内环境监测系统布线困难、灵活性差的弊端,设计了一种基于ZigBee无线传感器网络的室内环境监测预警系统;该系统综合运用了ZigBee网络通信技术、嵌入式Web服务器技术和GSM通信技术,利用终端节点对室内温湿度、一氧化碳体积分数、甲醛浓度等环境信息进行实时采集和监测;用户可通过打开Web网页完成对室内环境的本地和远程监测,当发生火灾或者煤气泄漏时,用户会及时收到报警短信;实验证明:该系统具有工作稳定、使用简单、灵活性好的优点,具有较高的实用价值与广泛的应用前景。
Considering the disadvantage of indoor environment monitoring system on wiring and flexibility, an indoor environment moni- toring and early warning system based on ZigBee wireless sensor networks is designed. This system combines ZigBee network communication technology, embedded web server technology and GSM communication technology. Indoor temperature, humidity, CO volume fraction and formaldehyde concentration are collected and monitored real--time with terminal node. Users can realize local and remote monitoring of in- door environmental quality through the web page and receive alarm information in a timely manner when a fire or a gas leakage occurs. The experimental results show that the system has the advantages of stability, simplicity, flexibility, and has high practical value and a wide ap- plication prospect.
