Design And Implementation Of Environmental Pollution Monitoring And Alarm System In Smart Community

With the growing improvement of Chinese economic strength,and there comes some environmental pollution problems.Currently,the environmental pollution in urban areas has gradually affected people's normal life,but most of existing environmental monitoring systems has disadvantage in monitoring factors,weak comprehensive analysis and poor real-time performance.Therefore,it's necessary to develop an environmental pollution monitoring and alarm system which with perfect function,good real-time performance,and high cost-efficient.It's has great significant to prevent serious pollution incidents and improve the quality of life of community.In this paper,we comprehensive use sensor network technology,embedded development technology,data fusion technology and database technology to design and realize an environmental pollution monitor and alarm system which integrates data collection,analysis,alarm transmission and processing.The system mainly consists of two parts:environmental monitoring terminal,environmental pollution monitoring and management platform.Environmental monitoring terminal uses STM32 and S3C6410 as the core processors,and expands noise,light intensity,PM2.5,toxic gas and other sensors.It also adds GPS,camera and other modules.All these modules and sensors are used to realize acquisition of the environmental data,location information and videos in real time.These collected data will be send to environmental pollution monitoring management platform.The environmental monitoring management platform includes three parts:environmental pollution monitoring server,Web server and mobile terminal.The environmental monitoring server is developed in C#.It could provide user with humanized interface,and functions of data receiving,display,storage and analysis.The Web server is developed by JSP and Java.It provides user with functions of pollution data view,location search and real-time video monitoring.It also provides alarm and task dispatch services when data are abnormal.Mobil phone terminal is developed by Android.It mainly realize real-time data reception,display,abnormal prompt and remote video monitoring,as well as view dispatch tasks,route guidance,and so on.The test results show that the environmental pollution monitoring and alarm system runs stable,and completely realize real-time acquisition and transmission data of noise,PM2.5,toxic gas concentration,GPS and videos.The environmental pollution monitoring server can achieve real-time data receiving from multi-node,data analysis and alarm.The Web server realizes functions of data view and task dispatch.The mobile phone can inform the inspection of pollution information in time,it provide a reliable guarantee for the management of environmental pollution problems.
