Design And Implementation Of A Scene Construction System For Intelligent Fresh Air Devices

With the popularity of intelligent fresh air devices,the control experience of the devices will affect the acceptance of users.This thesis designs and implements a scene construction system for smart fresh air devices,taking users’existing devices as the most basic control unit and logically combining multiple devices with the concept of scenes,mainly including functions such as data display related to the combination of scenes and linkage control of multiple devices within the scenes.The system is available to users in the form of mobile application,which to a certain extent solves the situation of poor control experience when the number of devices increases in traditional smart home solutions,and can provide more efficient services to users of smart new air devices and system administrators.Compared to traditional means of controlling multiple devices,the solution proposed in this thesis takes more into account the correlation between devices and uses this to integrate data from multiple devices,ultimately presenting it to the user in the form of a mobile application.The scene construction scheme proposed in this thesis starts with two aspects:devices and scenes.For single intelligent fresh air devices such as fresh air machines and fans,basic data viewing and device control functions are provided;for the linkage of multiple devices,scenes are provided as control dimensions to realize the total data query and management of multiple devices within the scenes.This system is based on the remote control of the equipment,and the combination of logic is realized in the scene construction.Users can view the air information of the created scene in this system,send control commands through the message push module construction,and realize the application message push.At the same time,this system will collect the air quality data and user operation data acquired by the fresh air equipment during operation,and the user can query the operation records through the specified interface and acquire the data recorded by the equipment during operation.These data are stored in the specified database and used as the input source for the subsequent data analysis module to analyze the user’s environmental conditions and usage habits,etc.To ensure that users have similar scenario control experience in multiple platforms,this system adopts Flutter cross-platform UI framework,which can quickly generate a unified multi-platform client.Users can use the technology by downloading Apk file,adding and controlling devices,building,viewing and running scenes,running device operation analysis results through the interface and generating corresponding operation reports according to the corresponding indicators,which is highly practical for users of smart home products and company operators.
