【摘要】：室内环境监测是报告生活环境质量的重要手段。然而大型建筑物室内环境复杂、监测范围广,传统的有线网络监测具有成本高、工程量大、综合布线不方便等缺点。WSN因具有使用方便灵活、无须布线等优点,在环境监测中得到了越来越广泛的应用,将其应用于室内环境监测,可有效解决传统有线监测存在的问题。本文结合大型建筑物的室内监测需求以及WSN的结构特点,设计了基于WSN的室内环境监测系统,实现对建筑物室内的温度、湿度、有害气体浓度等环境参数的实时监测、报警、存储、查询等功能。主要完成了以下工作:1、室内WSN环境监测系统结构设计根据室内环境监测的一般需求,结合WSN网络体系结构,设计了室内环境监测系统结构;系统主要分为4大部分:监测中心、汇聚节点、传感器节点和用户应用客户端。2、环境监测WSN系统搭建以CC2530为核心,ZStack协议为网络通信基础,设计完成了汇聚节点和传感器节点,通过自组织构建室内环境监测WSN,传感器节点将采集到的数据通过汇聚节点转发给监测中心。整个系统网络呈树形结构,单个房间内呈以汇聚节点为中心的星型网络。并利用符号定位或粒子群优化的加权质心定位方法实现了监测数据的定位。3、环境监测中心设计用PC作为监测中心的环境监测数据服务器和应用服务器。其中数据库用SQL Server 2005实现了数据的存储和管理,应用服务器作为B/S架构的Web服务器为用户提供服务,Web服务器通过监听浏览器获取浏览器发出的请求,处理并返回相应的数据,实现用户管理、查询数据、显示采集信息等主要功能。后端使用JDBC技术管理数据库,用于存储与管理监测数据。4、环境监测Android APP设计Android的APP设计主要分为Java服务器设计和Android客户端设计。Java服务器主要完成与监测中心的对接,共享数据库,并通过APP的设计实现C/S结构的查询。Android客户端完成了用户登录、历史数据查询、实时显示等功能。服务器和客户端采用Wifi进行连接,通过Socket的通信方式。
[Abstract]:Indoor environmental monitoring is an important means to report the quality of living environment. However, the indoor environment of large buildings is complex and the monitoring scope is wide. The traditional wired network monitoring has high cost and large amount of engineering. Because of the advantages of convenient and flexible use and no wiring, WSN has been more and more widely used in environmental monitoring, which is applied to indoor environmental monitoring. This paper designs the indoor environment monitoring system based on WSN, which can realize the indoor temperature and humidity of the building, combined with the indoor monitoring requirements of large buildings and the structural characteristics of WSN, which can effectively solve the problems existing in the traditional wired monitoring. The functions of real-time monitoring, alarming, storing and querying of environmental parameters such as the concentration of harmful gases have mainly completed the following work: 1. The structure of indoor WSN environmental monitoring system is designed according to the general requirements of indoor environmental monitoring, and combined with the WSN network architecture, The structure of indoor environment monitoring system is designed, the system is divided into four parts: monitoring center, gathering node, sensor node and user application client. The WSN system is built based on CC2530 protocol. Through self-organizing the indoor environment monitoring WSNs, the sensor nodes transmit the collected data to the monitoring center through the convergent nodes. The whole system network presents a tree structure. In a single room, there is a star network centered on convergent nodes. The location of monitoring data is realized by means of symbolic localization or particle swarm optimization weighted centroid positioning method. The environment monitoring center is designed to use PC as the monitoring center. Environment monitoring data server and application server. The database uses SQL Server 2005 to store and manage the data. As the Web server of B / S architecture, the application server provides the service for users. The web server acquires the request from the browser by listening to the browser, processes and returns the corresponding data, realizes the user management, and queries the data. Display and collect information and other main functions. Back-end use of JDBC technology to manage the database, The APP design of environmental monitoring Android APP design Android is mainly divided into Java server design and Android client design .Java server mainly accomplishes docking with monitoring center and sharing database. Through the design of APP, the C / S structure query .Android client has completed the functions of user login, historical data query, real-time display and so on. The server and client are connected by Wifi, and the communication mode of Socket is adopted.
