为实现环境监测的自动化、实时化和网络化,设计了一种基于开源硬件的环境监测系统.将该系统架构设计为三层:感知层、网络层和应用层.感知层为基于开源硬件和传感器技术开发的智能终端,负责温湿度、PM2.5等环境数据的采集、封装处理和显示,并具备网络连接功能;网络层依托以太网传递监测数据;应用层采用Apache/Tomcat+Java+MySQL的B/S架构,实现数据的存储、分析和展示功能.运行结果表明该系统实时性好、数据采集精确、扩展性好,无线连网易于部署,可广泛应用于工农业、军事监测等领域.%To realize an automatic, real-time and networking environment monitoring system, a monitoring system based on open source hardware is designed , whose architecture contains three layers , sensing domain, network domain and application domain. The sensing domain consists of intelligent terminals based on open source hardware and sensors , which measures environment data of temperature , humidity and PM2.5, and packages, analyzes, displays data, and also has network connection function. The network domain is based on Ethernet to transmit data. The application domain is based on B/S architecture of Apache/Tomcat+Java+MySQL to implement functions of data storage , analysis and display. The system has the feature of real-time , high accuracy of data measuring , good extensibility , and easy for deployment due to its wireless network connection function. The system can be widely applied in environment monitoring of agriculture, industry, military and many other fields.
