Design And Implementation Of Urban Community Waste Classification Management System Based On Internet Of Things

With the development of urbanization and the increase of urban population in China,the output of municipal solid waste of urban residents has increased rapidly.How to use scientific and technological means to improve the service management level of community waste classification,so as to achieve the reduction,harmlessness and recycling of domestic waste has become an imminent social problem.According to the needs and problems in the process of urban community waste classification management,this paper designs a city community waste classification management system based on the Internet of Things technology.The specific contents are:(1)Designed and implemented a data collection device that can easily obtain garbage classification related information.The weight data of garbage is collected by a portable electronic scale.Resident information and garbage type information will be encoded on the barcode,and the barcode on the garbage bag will be scanned by the barcode scanning module for data collection.The MSP430 MCU receives the data from the sensor through the serial port,and coordinates and controls the operation timing of each module,thereby realizing the automation of data collection.(2)Designed and implemented a wireless data transmission device based on GPRS.Specifically,the SIM900 A wireless radio frequency module is used to perform data transmission through a get method based on the HTTP protocol.On the server side,a data receiving and parsing program is designed based on the php language,which receives and parses HTTP messages containing garbage classification related information in real time,and saves the data in the server database.(3)Designed and implemented a garbage classification web management platform based on the Laravel framework.The web management platform is developed based on LAMP(Linux + apache + My SQL + php),and uses the Layui framework for front-end UI design,which effectively implements service management functions such as data management,on-site garbage collection,and feedback.By using the urban community waste classification management system,the community can effectively record and manage residents' waste classification information,which helps to implement accurate waste classification rewards and penalties.In addition,the system also expands the convenience service function of community waste classification management,which helps the community to establish a long-term operation mechanism of waste classification management.
