基于ZigBee的图书馆环境监控系统设计

Design of Library Environmental Monitoring and Control System Based on ZigBee

图书馆中温度、湿度和光强等环境指标对图书保护有重要影响,因此研究灵敏、准确、高效的图书馆环境监控系统显得尤为重要。为了克服传统图书馆环境监控系统的布线麻烦、设备可移动性不强、精度差等缺点,提出了一种基于Zig Bee无线通讯技术的环境监控系统,可以检测采集环境条件中的温度、湿度和光强度等参数,通过无线传输由网关节点进行收集,并且发送到PC机,由上位机监控软件对网络采集的数据统一管理和分析。分析了Zig Bee无线监控系统的组成及其特点和功能,从软硬件两方面设计了系统中的各个节点,完成Zig Bee网络协调器节点、Zig Bee路由节点和Zig Bee传感器节点的设计。系统在Zig Bee2004协议栈基础上,通过对协议栈应用层添加和修改程序来实现系统功能的。下位机软件设计主要分为网络协调器程序、传感器节点程序和路由节点程序及上位机程序。

The environmental conditions in the museum such as temperature,humidity and light intensity have an important impact on the preservation of cultural relics.So it is very important to research a sensitive,accurate and efficient environmental monitoring system for the museum.The environmental monitoring and control system,based on ZigBee wireless communication technology,is presented to detect the acquisition parameters such as temperature,humidity and light intensity which collected by the gateway nodes,and sent to the PC for management and analysis of the data from the network unified, which overcomes the shortcomings of poor wiring, mobility and precision. The composition,characteristics and functions of the system are analyzed and each node in the system is designed in two aspects of hardware and software to complete design for ZigBee network coordinator node, ZigBee routing node and ZigBee sensor node.Based on 2004 ZigBee protocol stack,the system function is realized by adding the application layer protocol stacks and modifying the program.The PC software design of this system mainly consists of the network coordinator,sensor nodes and routing node and PC application program.
