Design And Implementation Of Indoor Intelligent Home Control System Based On Virtual Modeling Technology

The Times’ advancement,combined with the advancement of science and technology,has led to a heightened desire for quality of life,a greater requirement for living space,and a desire to utilize smart home products to satisfy these requirements.Smart homes are an effective combination of cutting-edge science and daily life,which has attracted wider attention and discussion.Currently,there are numerous smart home design platforms and software both domestically and internationally.However,traditional smart home systems are limited to a two-dimensional human-computer interaction interface,which cannot provide users with a good smart home experience.In recent years,virtual modeling technology has become an important scientific tool,it is not only widely used in the laboratory,but also has been extended to various fields.Based on the cooperation with a smart home company,this topic combined virtual model technology with smart home,by constructing a three-dimensional indoor scene model,users can control the smart home in the virtual scene,and bind the smart home in the virtual scene to the real equipment,so as to realize the mapping between the virtual and the real.Consequently,the nucleus of this study is the formation and realization of an indoor smart home system based on virtual modeling technology.Firstly,the development status of intelligent home control system is analyzed.After in-depth investigation,the research scheme of using virtual modeling technology to build intelligent home control system is determined.Secondly,this paper investigates the related literature of indoor scene generation in recent years,and proposes an indoor scene generation model(ISGSA)based on self-attention mechanism for indoor scene model generation.In order to achieve accurate control of smart home,this topic proposes a multi-layer semantic model of indoor space,which is divided into four levels according to the types and characteristics of smart home services:video layer,audio layer,temperature layer and weather layer,and carries out hierarchical virtual modeling of smart home devices at four levels,so as to realize users’control of smart home in virtual scenes.Users can adjust the location of the smart home in the virtual scene without providing real information,thus protecting the privacy of users.Finally,the system uses advanced infrared wireless control technology to connect the virtual environment with the smart home devices in the real world,so as to realize remote operation and collaborative management.Users can control the smart home devices in the virtual scene.This system uses the B/S architecture,with three.js as its core module,which can achieve 3D interactive display of indoor environments in the browser.Django and node.js are the web development frameworks,which together form a complete back end management system.Data is stored in the MySQL database,and the Redis database is responsible for data caching.After careful design,the development of the smart home control module,virtual character control module,indoor scene generation module,and back end management module have been implemented,achieving original design intent and obtaining satisfactory development results.Currently,functional and non-functional testing has been carried out on various functional modules of the system,and the system is in a good operating state,with no obvious functional defects,indicating that it has basically met the expected development requirements.
