Classroom electricity-saving control system based on ARM

Abstract

The present invention relates to the field of teaching resource monitoring technology and specifically discloses a classroom electricity-saving control system based on ARM. The system comprises a dataacquisition and control module that is used for collecting and monitoring the state that people go in and out of a classroom, a wired transmission module that is connected with the data acquisition and control module and used for transmitting the data collected by the data acquisition and control module to a server, and a display module that is connected with the wired transmission module and used for data display. The system provided by the invention achieves the advantages and goals that electric equipment in classrooms in colleges and universities is properly used, electricity is saved andteaching management is improved.

Description

technical field [0001] The invention relates to the technical field of teaching resource monitoring, in particular to an ARM-based classroom power-saving control system. Background technique [0002] As an important place for teaching in colleges and universities, classrooms generally adopt an open management model. Students basically have no fixed class classrooms and no fixed seats; and floor managers are only responsible for hygiene or security work. Therefore, it is commonplace in colleges and universities to cause the lights to stay on during the day, and no one to turn on the lights at night, the lights are fully turned on when there are few people, and the ineffective operation of electric fans in summer. We can make an estimate, taking the use of lights in a school teaching building as an example: Suppose there are a total of 12 fluorescent lamps in the classroom, each fluorescent lamp is 40w, and there are 30 classrooms on each floor, with a total of 8 floors, plus ...

AI Technical Summary

Problems solved by technology

The reasons for the analysis are as follows: 1. When the external light intensity exceeds the illuminance of the lamps, it is difficult for human eyes to detect the presence of lights; 2. Teachers and students concentrate on teaching and learning, and it is impossible to be distracted to observe changes in classroom illuminance. It is also impossible to take the initiative to turn off the lights; 3. It is difficult for the classroom management staff to understand the actual situation of each floor and each facing classroom, coupled with the influence of individual cognitive differences, it is difficult to make scientific and accurate judgments, and they are responsible Turn on and off the lamps, either turn off the lights too early or turn on the lights too late to cause students to see clearly, or turn off the lights too late or turn on the lights too early to cause waste
