Energy-saving intelligent illumination control device and method

Abstract

The invention provides an energy-saving intelligent illumination control device and method. The energy-saving intelligent illumination control device controls opening or closing of indoor illumination devices via indoor brightness and existence of people, and comprises an ambient brightness acquisition module, a human body signal acquisition module, a main-control module and a switch control module, wherein the ambient brightness acquisition module comprises a light dependent resistor and a comparator, and is used for collecting indoor brightness data, and comparing the indoor brightness data with a preset value; the human body signal acquisition module comprises a pyroelectric body infrared sensor, and is used for judging whether people is in a room, and generating a human body signal if people is in the room; the main-control module is connected with the ambient brightness acquisition module and the human body signal acquisition module, and used for activating the ambient brightness acquisition module via the human body signal and generating a control signal as per the compared result of the brightness data and the preset value; the switch control module comprises a plurality of electronic switches which are connected with the main-control module and illumination devices, and controls the on-off state of each illumination device via the control signal.

Description

technical field [0001] The invention relates to the technical field of lighting control, in particular to an energy-saving intelligent lighting control device and method. [0002] Background technique [0003] At present, it is common in school classrooms, offices, etc. When people leave the room (this phenomenon is more obvious in colleges and universities), most people do not form the habit of turning off the lights, so that when there is no one in the room, the lights are still on. , the waste of electric energy is obvious. [0004] The most common existing lighting control device is voice-activated equipment, which is usually installed in corridors and corridors. It judges whether there are people and lights up the lighting equipment by collecting ambient sound. The disadvantage of this equipment is that it is not sensitive and is easily disturbed by other sounds. , and the lighting device will still turn off suddenly when there are people. [0005] Contents of the ...
