摘要
针对环境参数有线监测存在的问题,设计并制作6个传感器节点和1个协调器的无线环境参数监测系统。提出地址匹配和导引码识别相结合的应用层通信协议,使协调器与传感器节点组成1个稳定的树形拓扑网络,扩大监测范围。协调器通过网络收集各传感器节点采集的环境参数(空气温、湿度,光照强度等),经串口将数据传送给SIM300模块,利用GSM/GPRS网络与客户端进行信息交互。无线环境监测系统可以在大区域内和复杂环境下正确监测温、湿度、光照强度,系统能接收用户的短信指令,将环境参数信息返回给用户,实现远程监测。系统可应用于气象环保、煤矿工业、精准农业等领域。
According to the existing problems of wired monitoring environmental parameter, six sensor nodes and a coordinator of intelligent wireless environment parameter monitoring system was designed and made. The communication protocol of application layer was proposed by combination address matching and guidance code identification. It makes the coordinator and sensor nodes form a stable tree topology network ,to enlarge the monitoring range. The coordinator collects the environment parameters （air temperature, humidity, light intensity, etc. ） of every node through the network, then sends data to SIM300 module by the serial port, and using the GSM/GPRS network to realize user interaction. The wireless environment monitoring system can be adopted to correctly monitor temperature, humidity and light intensity of large-scale complex environmental and irregular regions. This system can receive the user＇s SMS, and return the environmental parameter back to the user, to realize remote-monitoring. This system can be applied in meteorological environmental protection, coal-mining industry, precision agriculture and so on.
