基于ZigBee的无线环境监测系统设计
摘 要
随着时代的发展人们对环境监测的需求日益增多,为了实现监测一些复杂、偏远的环境,或是无法实时人为进入监测的环境,一种新兴的网络技术--无线传感器网络应运而生。本设计的目的就是运用无线传感器网络结合低功耗低成本的ZigBee技术对库房的温湿度进行监测,首先对无线传感器网络的发展做出简述并分析了Zigbee技术的特点、协议以及网络拓扑等。其次对系统进行总体设计,系统可大致分为三部分,数据的采集和处理部分,数据的传送部分,以及接收数据的上位机部分。其中数据采集部分采用SHT11温湿度传感器,与采用CC2530作为核心芯片的微处理器模块,共同工作在ZigBee的网络环境中,配合RS232串口,将数据传送到监控主机,并由主机返回具体操作。最后,对本系统的软件部分做出了程序框图的设计。由此构成一套完善的系统,帮助人们监测库房内的温度和湿度,做到及时的通风或者报警处理,避免对储物的影响或损坏。

Design of Wireless Environmental Monitoring
System base on ZigBee
Abstract
In recent years, the people's demand for the technology of environmental monitoring is increasing, in order to realize the monitoring of environment, where is complex, harsh, dangerous, or unable to enter in real time, a new network technology came out named wireless sensor network. The purpose of this design is to use wireless sensor network based on ZigBee technology which is low-power and low-cost to monitor the temperature and humidity of the storage. Firstly, the development of wireless sensor networks is briefly introduced, and the characteristics, protocols and network topology of ZigBee are also analyzed. Secondly, I made the overall design of the system, the system can be broadly divided into three parts: the part of the data acquisition and processing, the part of the data acceptance and transmission, and the part of the hosts for receiving and transmitting data. Which part of the data acquisition by SHT11 temperature and humidity sensors, and using CC2530 as the core chip microprocessor module, work together in the ZigBee network environment with the RS232 serial port, will transfer data to the monitoring host, and by the host returns the specific operation. Finally, the software of this system has made the design of the program block diagram. This constitutes a sound system to help people monitor the temperature and humidity inside the warehouse, so that timely ventilation or alarm processing, to avoid the impact or damage to the reservoir.
