摘要
为了使无线传感器网络节点获得更好的通信效果,给出了采用TI公司的CC2530作为主芯片对ZigBee网络中的协调器节点进行设计的方法。该方法选用TI公司的CC2591作为射频前端芯片,并给出了硬件设计中各功能模块的连接方式,同时对协调器组建网络及子节点通过关联协调器节点接入网络进行了分析。实际测试结果表明,该设计的节点通信距离较远且接收灵敏度高,能适用于智能家居等多种场合。
To get better communication performance, a design method of ZigBee coordinator node based on TI CC2530 used as the main chip and CC 2591 the RF front-end chip is given, also presented is the connection mode among functional modules in the hardware design. An analysis is made about coordinator networking and network access of child nodes via coordinator node associated. An actual test results show that the coordinator node designed has a further communication distance, a higher receive sensitivity and can be applied to a variety of occasions such as smart home.
