ZigBee是一种具有耗能低、成本低、复杂度低、网络容量大、安全性高、工作频段灵活、延时短等优点的无线技术。以Jennic公司JN5121模块作为ZigBee节点模块的控制板,设计开发了ZigBee无线网络系统,并以ZigBee中心节点为例对其供电电路、串口通信电路、ZigBee无线网络建立及通信流程等进行了详细介绍。所设计的基于ZigBee的无线远程监测系统在现代电站设备远程状态监测中具有较好应用前景。
ZigBee is a wireless technology with the advantages of low energy consumption, low cost, low complexity, large network capacity, high security, flexible working frequency band and short delay. Taking Jennic JN5121 module as the control board of the ZigBee node module, the ZigBee wireless network system is designed and developed. The power supply circuit, serial communication circuit, ZigBee wireless network establishment and communication process are described in detail by taking the ZigBee central node as an example. The designed ZigBee-based wireless remote monitoring system has good application prospects in the remote condition monitoring of modern power plant equipment.
