【摘要】：近年来,随着工业现代化的不断推进,各种污染气体的排放量也急剧增加,使得大气环境污染越来越严重,尤其是城市地面大气环境中污染气体时空分布呈现复杂化、多样化和局域化的趋势。传统的大气环境监测仅依靠零星分布的监测基站、人工采样、人工分析,早已不能全面、准确的反应大气污染状况,建立一个密集节点分布、易组网,能够实时、有效、全面的监测大气环境信息的监测系统势在必行。物联网技术的飞速发展以及安卓智能手机在日常生活中的普及,为本文设计的面向安卓终端的物联网监测系统提供了必要条件。本文详细的阐述了该系统的总体设计方案,其主要分为三部分:数据采集端(监测节点)、服务器端和数据展示终端(Android App)。数据采集端将采集到的大气环境信息通过GPRS通信上传到服务器端;服务器端负责接收信息、对信息进行分类和存储、支持多种方式查看实时大气环境信息和历史大气环境信息、查看监测节点分布、对监测节点和工作人员进行管理;数据展示终端通过访问服务器端数据库和调用百度地图API将大气环境信息及时、有效的展示给普通用户。具体研究内容如下:(1)在数据采集端,主控芯片LPC2138将模拟的大气环境信息经过放大、A/D转换后转变成数字信号,通过GPRS模块上传到服务器端。负责采集信息的传感器阵列由四种电化学式气体传感器和SHT10温湿度传感器组成,能够实时采集大气环境中NO2、SO2、CO、O3四种气态污染物基本项目浓度和温湿度;数据采集端体积小、布设便捷,可根据城市的功能区、污染源和监测目的的不同随时调整布设密度和高度。(2)在服务器端,接收窗口对端口创建Server Socket来实时接收数据采集端上传的大气环境信息,并对该信息进行分类后存储在数据库相应表中,同时服务器端的监控中心可以查看监测节点的分布情况、实时大气环境信息和历史大气环境信息,还可以对监测节点和系统管理人员进行增、删、改、查等操作。(3)数据展示终端是一款基于Java语言开发的安卓手机App(Application),采用C/S模式,能够读取服务器的数据库表,实现的功能有用户注册与登录、地点查询、手机定位、数据读取和显示。
[Abstract]:In recent years, with the continuous promotion of industrial modernization, the emissions of various polluting gases have increased sharply, which makes the atmospheric environment pollution more and more serious, especially the space-time distribution of the polluted gases in the urban surface atmospheric environment is becoming more and more complicated. The trend towards diversification and localization. Traditional atmospheric environment monitoring only depends on scattered monitoring base stations, manual sampling, manual analysis, has been unable to comprehensively and accurately reflect the situation of air pollution, establish a dense node distribution, easy to form a network, can be real-time, effective, A comprehensive monitoring system for monitoring atmospheric environmental information is imperative. With the rapid development of Internet of things technology and the popularization of Android smart phone in daily life, this paper provides the necessary conditions for the Android terminal oriented IOT monitoring system. This paper describes the overall design of the system in detail, which is mainly divided into three parts: data acquisition terminal (monitoring node, server and data display terminal) Android Appellation. The data acquisition terminal uploads the collected atmospheric environment information to the server through GPRS communication, the server is responsible for receiving information, classifying and storing the information, and supporting various ways to view real-time atmospheric environment information and historical atmospheric environment information. Check the distribution of monitoring nodes, monitor nodes and staff management; data display terminal through accessing the server database and calling Baidu map API to air environment information timely, effective display to ordinary users. The detailed research contents are as follows: (1) at the data acquisition end, the main control chip LPC2138 converts the simulated atmospheric environment information into digital signal after amplifying the AP-D conversion, and uploads it to the server through the GPRS module. The sensor array, which is responsible for collecting information, consists of four electrochemical gas sensors and SHT10 temperature and humidity sensors, which can collect the basic concentrations and temperature and humidity of four gaseous pollutants in the atmospheric environment in real time. It is convenient to set up, according to the function area of the city, the density and height of the layout can be adjusted at any time according to the function area of the city, the pollution source and the monitoring purpose.) on the server side, the receiving window creates the Server Socket to the port to receive the atmospheric environment information uploaded from the data collection terminal in real time. The information is classified and stored in the corresponding tables of the database. At the same time, the monitoring center on the server side can view the distribution of monitoring nodes, real-time atmospheric environment information and historical atmospheric environment information. Monitoring nodes and system administrators can also be added, deleted, modified, checked and so on. The data display terminal is an Android App Application device based on Java, which uses C / S mode to read the server's database tables. The functions are user registration and login, location query, mobile phone location, data reading and display.
