Intelligent Classroom Energy Efficiency Management System Design

With the continuous growth of China’s national strength,the energy problem is becoming increasingly serious,the state constantly advocates the strategic consciousness of "energy conservation and emission reduction",thus vigorously promotes the construction of new sustainable "green campus" in colleges and universities.Thus,under the operation of compatible with traditional classroom teaching mode,a new mode of "smart classroom energy efficiency Management system" is constructed by integrating the embedded technologies such as the Internet of Things serial communication.This paper mainly includes:Conduct field analysis and statistics on the electricity consumption of classrooms in THE campus of BJTU,and explore the current energy consumption rule of traditional classrooms by analyzing the load characteristics of classrooms in different periods and seasons.In the context of meeting the traditional classroom teaching mode,explore and design a new and more "clean" and "high energy efficiency" intelligent classroom energy efficiency management system architecture design.The implementation scheme of higher energy efficiency intelligent classroom energy efficiency management system was proposed and designed by using Internet of Things embedded technology and network communication technology.Based on Modbus protocol RS-485 communication and wireless communication protocol as the energy efficiency system communication architecture,with infrared light sensors,temperature and humidity sensor and air quality detection device as a real-time perception layer module,reading teaching from the number recognition camera and server system schedule of classroom lighting,air conditioning and projectors and other modules of intelligent control of energy efficiency.The main camera module can give instructions to the slave device and receive manual control commands.Experimental field tests verify that the smart classroom energy efficiency management system can effectively meet the needs of more energy saving and high energy efficiency in the classroom mode situation,and the system realizes stable,accurate,efficient and sustainable operation and transmission of instruction data.To explore self-study classroom use mode,in class and out mode,control logic of lighting,air conditioning and projector design,in self-study mode to realize the people walk lamp,less and less light,set up suitable air conditioning temperature to satisfy the present environment,in the class mode set the lighting control strategy of projector mode,As well as the off-field mode to achieve the power of the whole classroom energy-saving control.The camera module of number recognition algorithm,through the study of the corrosion of the camera monitoring image expansion operation of statistics,which can identify the number of classroom to give orders to the classroom efficiency control module for real-time control,and can through the terminal server real-time display information such as the number of classroom environment on mobile APP and display outside the classroom.To sum up,this article is based on load design for north jiaotong university campus in order to solve the classroom efficiency question the wisdom of the management system of energy efficiency design,field tests prove that the scheme can realize intelligent control,energy consumption for classroom problem has the corresponding improvement,promote the use of students and teachers in the classroom experience.The scheme is reliable and stable,and has strong practical significance and promotion value.
