ZigBee在室内环境监测系统中的应用

随着我国经济的快速发展,由室内环境问题而引起的人口健康问题越来越突出,已经引起广大人民群众的广泛关注。本文提出一种基于ZigBee的无线传感器网络在室内环境监测方案,对系统的软硬件进行了研究与设计。以CC2430芯片为无线节点的检测与信息处理核心,与现代传感器模块相结合,构成无线传感器网络终端检测子节点;采用RS232标准的方式与中心节点进行信息通讯,使现场循环检测数据能实时传送给中央监控计算机,实现室内环境的实时监测。结果表明,系统功能维护容易、扩展方便、布网灵活、施工成本低,为室内环境现代化管理奠定了基础。

Application of ZigBee in indoor environment monitoring system

With rapid economic development of China, the masses have paid more and more attention to the indoor environmental problems which have been getting worse. The quality of indoor environment has directly related to people’s health and safety.therefore, this paper makes an indoor environment monitoring proposal based on the ZigBee technology wireless sensor network. In the same time, this paper conducts the research and design of hardware and software. CC2430 chip is considered as the core of information processing and wireless nodes detection. The terminal child-nodes of the wireless sensor network is established with modern sensor modules. It corresponds with central node in RS232 manner. As a result the detecting information at the scene is transferred to central monitoring computer in real time. The system fulfills real-time detecting in the indoor environment. Results show that the system has the characteristics of easy maintenance, good expansibility, networking flexibility and low cost. The design lays a foundation for modem management of the indoor environment.
