校园环境信息采集系统的设计与实现

Design and Implementation of Environmental Information Acquisition System for Campus

针对传统环境信息采集系统存在成本高和监测设备布局不灵活等问题,在对校园环境监测需求分析的基础上,提出了一个低成本的校园环境信息采集系统设计方案。在校园内部署传感器节点,实时采集温度、湿度、噪声和空气污染物等环境数据。利用Zigbee无线传感器网络技术,将数据通过网关汇集到监控主机,实现对校园环境的实时监测。详细阐述了传感器节点和服务器端的设计以及实现方法,实验证明该设计方案合理可行,工作性能稳定,能够实时采集并处理环境数据。

For the issues existing in the traditional environmental information acquisition system, such as high costs, inflexibility of acquisition equipment layout and so on, proposed a low-cost scheme of campus environmental information acquisition system according to the functional requirements. Envi-ronmental information, such as temperature, humidity, noise, air contaminants and so on, was collected in real time by sensor nodes that were deployed on campus. By the Zigbee wireless sensor network technol-ogy, the data was pooled to the server through the gateway, and then was processed into a graphical user interface that could monitor real-time campus environmental quality. The design of system is described in detail, includes acquisition node and the server. The experiment shows that the system is reasonable and feasible, it can realize timely collection, and works stable during data processing.
