基于ZigBee无线传感的空气温湿度监测系统设计

摘要

The air temperature and humidity monitoring system based on ZigBee wireless sensing was designed. The ZigBee wireless network is formed by a coordinator,multi routers and terminal device. The data acquired by the sensor are transmitted to coordinator's nodes after processing,and then transmitted from the coordinator's nodes to PC through the serial port for dis-play. The software system is designed by means of IAR integrated development environment and Zstack protocol stack of TI. The observation of air temperature and humidity was realized by taking TI CC2530 chip as the processor of the hardware system. Three aspects of system architecture,hardware and software were considered in the process of the system design,and ZigBee wireless sensing network was built successfully. This system has better transplantation ability,can be extended and connected with else sensors,and be applied to other fields.%设计了一种基于ZigBee无线传感的空气温湿度监测系统.其由一个协调器和多个路由器、终端设备形成Zig-Bee无线网络,把传感器采集数据处理后发送到协调器节点,协调器节点通过串口发送到PC进行显示.利用IAR集成开发环境和TI公司Zstack协议栈进行软件系统的设计,TI公司的CC2530芯片作为硬件系统的处理器,实现了对于空气温湿度的随时观测.设计从系统架构、硬件、软件3个方面进行思考和设计,成功建立了ZigBee无线传感网络.系统移植能力强,可扩展连接其他传感器,应用到其他领域.
