ZigBee无线传感器网络在TWP3风廓线雷达系统中的应用
Application of ZigBee Wireless Sensor Network in the TWP3 Wind Profile Radar System
中文摘要：
风廓线雷达状态信息、机房室内外环境信息的采集与上传是十分必要的。传统方案是利用主控计算机串口，采用RS232或RS422等有线通信协议读取这些信息。这种方案存在布线繁琐、计算机串口数量有限、传感器数量不易增加等缺点。ZigBee无线传感器网络是物联网技术中的一种。通过采用ZigBee芯片CC2538将雷达状态监视器和室内外环境信息检测电路板设置为网络终端节点，将雷达主控计算机连接ZigBee通信模块设置为网络协调器，组建了一个小型的星形ZigBee无线传感器网络。该网络通信可靠、布线简单、节省串口、扩容方便，为TWP3风廓线雷达进一步拥抱物联网提供了思路。

Abstract：
It is of importance to collect and upload wind profiler radar status as well as indoor and outdoor environment. The traditional scheme is to read the information through the serial port of the master computer, based on the cable communication protocols such as RS232 or RS422. This scheme has the disadvantages of complicated wiring, limited number of computer serial ports, and difficulty in increasing the number of sensors. The ZigBee wireless sensor network is a new scheme., The radar status monitor and indoor and outdoor environment information detection circuit board are set to network terminal nodes with the ZigBee chip CC2538. The master computer is installed with a ZigBee communication module into network co-ordinator. A small star-shaped ZigBee wireless sensor network is established. The network communication is reliable, the wiring is simple, the serial port is saved, and the expansion is convenient, which provides an idea for the further Internet-of-Things transformation of wind profiler radar.
