| With the progress of urbanization in China,a large number of people have entered the city,but the urban area has not expanded in the same proportion with the growth of urban population,the urban green area is increasingly scarce,and the urban residential and ecological environment is deteriorating.The contradiction between people’s growing demand for greening and the scarcity of urban greening area has gradually emerged.As an important way to improve the life and living environment of urban residents,indoor greening has many benefits to human physical and mental health.in order to solve the practical problems of "no place to raise","maintenance difficulty" and "high maintenance cost" encountered in the process of urban indoor greening promotion,a set of indoor three-dimensional green plant maintenance system based on Internet of things is designed and implemented in this paper.The main work of this paper is as follows:(1)Investigate the subdivided field of indoor three-dimensional greening,deeply understand the development of three-dimensional greening at home and abroad,and analyze and summarize the key practical problems encountered in the process of indoor greening promotion.(2)Carry out detailed demand analysis,correctly design and locate the system according to the target user group and application scene,divide the functional and non-functional requirements,and confirm that the main functions of the system are:user registration and login,Internet of things device management,plant growth environment information monitoring,video surveillance,remote control,data report six major items.(3)Study the three-dimensional planting and maintenance technology of green plants,design and complete the three-dimensional planting structure,and use low-cost and mature and reliable devices to build hardware control circuits based on NodeMCU to form the terminal of the Internet of things.(4)Learning the key software development technologies needed by the system,based on the idea of micro service,realizes the Internet of things platform server based on Dubbo+SpringBoot,designs and implements a set of simple and efficient system front-end interaction interface.This paper mainly contains the following innovations.Innovation one,the three-dimensional green planting mode based on indoor metope space.Different from the traditional ground flowerpot greening,this paper puts the plant species on the wall through the three-dimensional planting structure,which reduces the occupation of indoor space and solves the problem of "no place to raise".The second innovation is a three-dimensional planting structure for interior space and intelligent maintenance.Different from the existing vertical greening growth modules in the market,the three-dimensional planting structure is designed for indoor space and intelligent maintenance,with the overall use of modular ideas,low construction requirements,convenient disassembly and transportation,and can be customized.The third innovation is the intelligent maintenance system based on the Internet of things.The intelligent maintenance system designed in this paper is composed of hardware and Internet of things platform,which has many functions such as plant growth environment information monitoring,video surveillance,remote control,data report,equipment management,login and registration,etc.Through automatic and intelligent information acquisition and maintenance means,the threshold and cost of green plant maintenance are reduced.The problems of "maintenance difficulty" and "high maintenance cost" which hinder the promotion of indoor greening are well solved.The traditional indoor flowerpot greening takes up a lot of ground space,and mostly adopts the way of manual maintenance,which causes difficulties in the maintenance of green plants,consumes a lot of manpower and material resources,and hinders the further promotion of indoor greening.The indoor three-dimensional green plant maintenance system based on the Internet of things designed in this paper provides users with an one-stop solution for indoor greening.By introducing three-dimensional green plant planting technology and remote digital maintenance technology,the occupation of indoor ground space is reduced,the difficulty and cost of indoor greening maintenance are reduced,and a new idea is provided for the promotion of indoor greening. |
