The traditional environmental monitoring system has the problems of complex wiring and low data transmission rate,and its monitoring points are difficult to move,so a networking environment monitoring system based on ZigBee protocol is designed. The environmental temperature and humidity information is collected by SHT11 sensor,transmitted through ZigBee network,and sent to the monitoring center via 4G network for storage and recording. The whole composition of the system is in-troduced. The coordinator,terminal node,software design and data correction of the system are analyzed in detail. The system was tested strictly. The test results show that the system can accurately acquire the information with small error,is suitable for the occasions of laboratory,archive room,food storage and cold chain environments,and has wide application prospect.%针对传统环境监测系统布线复杂且监测点不易移动、数据传输速率慢等多种问题,设计一种基于ZigBee协议的可组网环境监测系统,利用SHT11传感器采集环境温湿度信息,基于ZigBee网络传递采集的信息,通过4G网络远传到监控中心存储记录,介绍了系统的整体构成,对系统的协调器、终端节点、软件设计、数据矫正等做了详细的分析,并对系统进行了严格的测试,测试结果表明,该系统能够准确地完成采集并具有较小的误差,适合实验室、档案室、食品储存、冷链环境等多种场合,具有广泛的应用前景.
