摘要
通过比较各种短距离无线通信技术,选取ZigBee无线传输技术作为智能家居系统无线传输设计。介绍了ZigBee的网络结构和ZigBee芯片选型,并分析基于CC2530的组网流程。结合系统设计,给出了终端节点RF无线收发核心模块、模拟开关量多路复用及串口转USB通信模块、温度传感器采集模块的硬件电路设计,并简述了节点传输及数据采集、网络协调器与节点协同工作的流程设计。最终,在不加PA(功放)增益的情况下,测得ZigBee无线传输模块有效传输距离为90 m,能满足组建智能家居个人无线网的需求。
By comparing a variety of short-range wireless communications technologies, the ZigBee wireless technology is selected for a wireless transmission system design of smart home system. The network structure of ZigBee and the ZigBee chip se- lection according to this design is introduced. The networking process based on CC2530 is analyzed. In combination with the sys- tem design, the hardware circuit design of terminal node RF transceiver core module, analog switch multiplexer and serial to USB communication module and temperature sensor acquisition module is given, and the node transmission, data acquisition, process design of network coordinator and node collaborative work are described briefly. In the absence of PA (power amplifier) gain, the effective transmission distance of the measured ZigBee wireless transmission module is 90 m, which can meet the needs of individual wireless networks of intelligent home.
