摘要
采用JN5139无线微处理器和无线传感器网络技术实现无线温湿度监控系统;系统采用ZigBee协议,通过星形拓扑组网完成现场传感器数据的采集以及温湿度控制信号的无线传送;上位机使用LabVIEW实现数据接收、处理和显示;文中介绍了协调器、路由器节点的软硬件设计,LabVIEW通信程序及界面的设计;经过实际测试,系统在距离300m范围内可实现误码率为0的可靠通信,通过增加路由节点,通信距离可达700m。实验结果表明,该系统可方便地用于普通家庭中的无线温湿度控制,并可广泛用于智能家居、粮仓、变电站等需要温湿度监控的场所。
The JN5139 wireless microprocessor and wireless sensor network is adopted to realize wireless temperature and humidity con-trol system. ZigBee protocol is adopted in the system to accomplish the field data acquisition and transformation through star topology net-work. The LabVIEW is used to achieve data acquisition, process and display. This paper introduces the hardware design and software design of coordinator and router nodes, and the design of LabVIEW interface. Through the actual test, the system can realize the reliable communi-cation of zero error rate within 300 meters, by adding a route node, the communication distance can reach 700 meters. The experimental re-sults show that the system can be easily used in the ordinary families for temperature and humidity control, and it could be widely used in in-telligent household, granaries, substation and so on, where the temperature and humidity need to be monitored.
