Description

Energy-saving light controller

Technical field

The utility model relates to a kind of light controller, especially a kind of energy-saving light controller.

Background technology

Along with lighting apparatus needs sharply to increase, and because the limitation of the not in place and illuminator of management itself, often cause the huge waste of electric energy.Traditional lighting control system generally is based on sound or photocontrol, has single, sensitive, the defective such as precision is not high, scope is low inadequately of detection mode, often has waste of electric energy.

Summary of the invention

In order to overcome above-mentioned problem; The utility model provides a kind of energy-saving light controller; With the single-chip microcomputer master control is core, by faint sound amplification detection, visible light detect, module such as stepping motor rotation pyroelectric infrared sensor, A/D conversion, liquid crystal display and control circuit form.

The utility model provides a kind of energy-saving light controller; Comprise sound intensity detection module, light detection module, multi-channel A/D modular converter, rpyroelectric infrared sensing module, master control module, key-press module, display module, relay control module; It is characterized in that: the master control module is connected with multi-channel A/D modular converter, rpyroelectric infrared sensing module, key-press module, display module, relay control module respectively, and multi-channel A/D modular converter also is connected with sound intensity detection module, light detection module.Sound, light data that light detection module, sound intensity detection module detect convert digital quantity into through multi-channel A/D modular converter, send into master control module logical process; Show through display module; When light intensity value during less than the threshold values of light, and the intensity of sound starts the infrared ray whether the rpyroelectric infrared sensing module detects has human body radiation greater than the threshold values of sound the time; Then relay module unlatching lighting installation is arranged, and key-press module can be provided with the threshold value of light, sound according to not comprovincial actual conditions.

The beneficial effect of the utility model is, can improve reliability, the detectivity of lighting control system greatly, is specially adapted to public arenas such as colleges and universities classroom, corridor; Realize the intellectuality of lamp control; Thereby saves energy, environmental protection, convenient management has important practical significance.
