Intelligent control device of classroom lamplight

Abstract

The invention discloses an intelligent control device of classroom lamplight and relates to the technical field of lamplight control. The intelligent control device of classroom lamplight comprises a single-chip microcomputer, a human body infrared sensor module, an illumination sensor, keys, a photoelectric coupler, a relay, a liquid crystal display and a direct-current stabilized power source. The single-chip microcomputer is connected with the human body infrared sensor module, the illumination sensor, the keys, the photoelectric coupler, the liquid crystal display and the direct-current stabilized power source, the photoelectric coupler is connected with the relay, and the direct-current stabilized power source is connected with the human body infrared sensor module, the illumination sensor, the keys and the liquid crystal display. The model of the single-chip microcomputer is AT89C52. Through the intelligent control device of classroom lamplight, electric energy can be utilized more reasonably in a school, and the operation cost of the school is reduced.

Description

Technical field [0001] The invention relates to the technical field of lighting control, in particular to an intelligent control device for classroom lighting. Background technique [0002] At present, the lighting management of university teaching buildings is basically in a state of extensive management. Its management is generally divided into the following three forms: one is no special person management, which is controlled by the students to turn on, and then the students on duty turn off the lights after self-study at noon, afternoon and evening; the other is to use a time switch to turn on and off according to the work and rest time The lighting power supply of the entire teaching building; third is the responsibility of a dedicated person, that is, the management personnel control the lighting power supply according to the schedule and weather conditions. [0003] The requirement for lighting management in the teaching building is to save electricity as much as possible u...

Problems solved by technology

The above three management models all have different defects.

The disadvantage of the first mode is that the human eye is not sensitive to weak light under strong light, and it is difficult to perceive the existence of light when the natural light is greater than the light of the lamp. This is the main reason for the long-lasting light during the day. The heart is not strong, and it will also cause the rest time and the long light of the night

Compared with the previous mode, the second mode has a great improvement in energy saving, but its disadvantage is that it cannot guarantee the light intensity of each classroom in time, because natural light is not only affected by known factors such as time and season, but also Affected by uncertain factors such as weather, this model is difficult to meet management requirements, and it is very likely that it will not meet the light intensity requirements

The third mode has greatly improved both light intensity and energy saving, but it needs special personnel to be in charge, and the accuracy of control varies from person to person, so it is difficult to be precise
