Development Of The Energy Saving Control System Of The Classroom Appliances Based On The Embedded System

At present, the traditional lighting is changing with the amazing speed to the intelligent control, which is the inevitable result of the development of science and technology, especially the Internet of things technology. However, since today’s colleges and universities have their own needs, so the energy consumption and the amount of lighting is very serious. The national "Twelfth Five Year Plan" also put the construction of a conservation oriented campus into an urgent need to solve the problem, continue to transform the campus lighting, to save the direction of saving, intelligent direction.At this stage, the focus of energy saving and emission reduction is mainly concentrated in the large and medium high energy consumption enterprises and institutions, their energy saving can play an immediate effect, but the university campus energy-saving emission reduction work is mainly concentrated in the laboratory stage. This paper is to achieve the purpose of intelligent control and saving campus through the transformation of the energy consuming and the most important lighting system in the campus. In this paper, we use the RFID technology to achieve the effective positioning of all personnel in the classroom. According to the design of school work and rest time and the field environment, the effective lighting, which can achieve the effective use of the light, is achieved. Finally, through the man-machine interactive system, realize the unified monitoring and debugging of the whole teaching building.The biggest advantage of the system lies in the fixed indoor environment, to achieve the effective positioning of personnel, the higher positioning accuracy, strong stability, is the basis for the realization of the lighting control, but also for students or teachers in school based on the school. In today’s society, with the continuous improvement of the Internet technology, the latter part of the indoor equipment or personnel positioning have more accurate requirements, so the system can be effectively used in the classroom, in the promotion process, can also provide reference for other systems.In this paper, a complete set of embedded control system is set up. Which includes embedded control platform based on ARM7, RFID based position acquisition and positioning system, independent light intensity acquisition system, and other auxiliary hardware systems. On the software side, the system realizes data exchange with the OPC server, and realizes the data exchange between human and computer interactive system and ARM control system. A set of man-machine interaction interface is designed, which is convenient to monitor and manage all the information in the system.
