Classroom illumination automatic monitoring method

Abstract

The invention discloses a classroom illumination automatic monitoring method. The method is realized through a classroom illumination automatic monitoring system. The classroom illumination automaticmonitoring system comprises a central processing unit, a plurality of illumination sensors, a plurality of control panels and a plurality of lamp sets. The classroom illumination automatic monitoringmethod comprises the steps of inputting correction illumination values U0 of all classrooms or corresponding local areas in all classrooms, and setting standard illumination values y (t) of the corresponding local areas; enabling the illumination sensors to collect an actual illumination simulation value corresponding to the local area; enabling the central processing unit to calculate an absolutevalue e (t) of an illumination difference value; comparing e (t) with U0, and determining whether to change the output signal of the control panels or not; and completing the monitoring process of all local areas. The purpose of accurately controlling the illumination of different areas in the classrooms is achieved, and the problems that students are amblyopia and electric energy is wasted due to the fact that the illumination in the classrooms cannot be automatically and accurately controlled are essentially solved.

Description

technical field [0001] The invention relates to a method for monitoring indoor lighting illuminance, in particular to an automatic monitoring method for classroom illuminance. Background technique [0002] According to the survey and research, as the myopia of primary and secondary school students shows an increasing trend year by year, one of the reasons is that it is difficult to take into account the saving of electricity and ensuring sufficient illumination in the classroom. At present, the main lighting control method is still based on human judgment. The intensity of the light is based on the manual switching of the lights. On the one hand, it causes the phenomenon that the lights will not be turned on when the illuminance is not obviously insufficient. On the other hand, different areas in the classroom get different natural light, resulting in different illuminance in each area. These The phenomenon will cause all or part of the classroom illumination to fail to meet...

[0002] According to the survey and research, as the myopia of primary and secondary school students shows an increasing trend year by year, one of the reasons is that it is difficult to take into account the saving of electricity and ensuring sufficient illumination in the classroom. At present, the main lighting control method is still based on human judgment. The intensity of the light is based on the manual switching of the lights. On the one hand, it causes the phenomenon that the lights will not be turned on when the illuminance is not obviously insufficient. On the other hand, different areas in the classroom get different natural light, resulting in different illuminance in each area. These Phenomena will cause all or partial illuminance of classrooms to fail to meet the national standard in certain periods of time, so it will lead to weakening of students' vision

[0003] In order to solve the above problems, a number of patent applications, including the invention patent application with the application number "201811189299.4" and the patent name "Classroom Lighting Control Method and System", have carried out some technical innovations in the automatic monitoring of classroom illumination. However, these patents The applications basically only disclose relatively simple lighting control devices and control methods, which are far from being able to realize the precise control of illumination in different areas according to the actual illumination monitoring in different areas in the classroom, so it is difficult to solve the essential problem
