摘要
针对智能家居、环境监测等的实际要求,设计了一种远距离通讯的无线传感器节点。该系统采用集射频与控制器于一体的第二代片上系统CC2530为核心模块,外接CC2591射频前端功放模块;软件上基于ZigBee2006协议栈,在ZStack通用模块基础上实现应用层各项功能。介绍了基于ZigBee协议构建无线数据采集网络,给出了传感器节点、协调器节点的硬件设计原理图及软件流程图。实验证明节点性能良好、通讯可靠,通讯距离较TI第一代产品有明显增大。
According to the actual needs of intelligent household,environmental monitoring etc,this paper designed a wireless sensor node of long-distance communication system.This system used the second SoC CC2530 set in RF and controller chips as the core module and externally connected with CC2591 RF front-end power amplifier module.Based on ZigBee2006 in software agreement stack,it realized each application layer function based on ZStack.It also introduced wireless data acquisition networks based on the ZigBee agreement construction,and has given the hardware design schematic diagram and the software flow chart of sensor node,synchronizer node.The experiment proved that the node is good in performance and the communication is reliable.The communication distance has increased obviously compared with the first generation TI product.
