Design And Application Of Intelligent Classroom Control System Based On Internet Of Thing

With the development of human industrial civilization,a large amount of carbon dioxide is released.The over-exploitation and rapid use of energy have destroyed the natural environment on which human beings live.The limited energy in the stratum also forces people to change the structure and mode of energy use.Aiming at the classroom application environment,this paper designs a classroom intelligent electrical control system.According to the characteristics of students' work and rest time,this system combined with intelligent control algorithm completed the functions of intelligent control of light,intelligent adjustment of temperature and humidity and intelligent switch of projection equipment.The intelligent electrical control system of classroom can effectively reduce the waste of power resources and achieve the goal of energy saving and emission reduction through networked intelligent control scheme.The main content of the paper is as follows:(1)The working principle of the intelligent electrical control system is introduced,and the corresponding control functions are completed according to the requirements of the intelligent electrical control system and the characteristics of the operating environment.In the classroom environment of colleges and universities,it is necessary to formulate detailed functions and system architecture according to the characteristics of large internal space of houses,large mobility of personnel and diverse functional requirements.(2)The hardware circuit design scheme of intelligent electrical control system is described.Firstly,the architecture of the system is introduced,Including the main control unit and sub-control unit hardware structure.This paper introduces the working principle of power conversion module,wireless communication module,contactor control module,raspberry pie main control board,environment detection module,temperature and humidity sensor module,LED driver module and FPGA control module in detail.(3)Expatiate on the software design scheme of intelligent electrical control system.Intelligent electrical control system is divided into the main control unit and sub-control unit,the main control unit focuses on the power supply module,wireless module and camera module control flow.The control flow of environment acquisition module,LED control module and infrared device control module is mainly described in the sub-control unit.The core control chip of the main control unit and the sub-control unit is different.(4)Test and analysis of intelligent electrical control system.The functional test of the intelligent electrical control system in the classroom mainly focuses on independent debugging of each equipment unit and joint debugging of modules,and carries out relevant algorithm analysis and data processing.The possible problems in the process of installation and debugging are analyzed,and the control theory and algorithm are concretized through concrete experiments.And the use of simulation,analysis,field measurement and other means to test,finally verified the intelligent electrical control system for lighting,temperature,humidity and peripheral intelligent control,to achieve the established design goals.To sum up,this paper designed a set of intelligent electrical control system for the classroom application environment.According to the characteristics of students' work and rest time,this system combined with intelligent control algorithm completed the functions of intelligent control of light,intelligent adjustment of temperature and humidity and intelligent switch of projection equipment.The intelligent electrical control system of classroom can effectively reduce the waste of power resources and achieve the goal of energy saving and emission reduction through networked intelligent control scheme...
