Based on the doppler effect of intelligent LED lighting control system, using bright degree of photosensitive resistance testing environment, when the surrounding environment is dark, light sensitive detection of the signals to single chip microcomputer, single chip microcomputer based on HB100 microwave sensor to detect whether there are pedestrians or vehicles object moves such as intelligent control the number of lights.Through the microcontroller STC89C52 set delay, between various lighting lighting replacement.The system is composed of intelligent control module and the 'normally on module, the intelligent control module by HB100 microwave sensor detection, light detection, STC89C52 single-chip computer, power supply and lED driver module.
Use in order to adapt to various environment, this system set 'normally on module.'normally on the module, as long as the photosensitive resistance test environment under the condition of the darker, normally on module will light up.'normally on the module is to facilitate the maintenance of the whole system, at the same time avoid without full dark objects moving environment does not apply to some environment.'normally on module to improve the intelligence of the doppler effect degree of application of light control system at the same time' normally on module on the number of LED lights relatively intelligent control part, there were fewer number of LED lights relatively general control system saves a lot of electricity.
Of our research is based on the doppler effect of light control system improved substantially in the detection and control, control of the equipment and monitoring elaboration to each lamp, has the good stability, and realized the purpose of saving energy.Under the current situation of energy shortage, it reflects the actual application on its energy saving, low manufacturing cost, stability and other advantages, including stability, the reliability of data transmission and communication lines of anti-jamming and so on, believe in the near future can be applied to real life, and brings good opportunity of development and market prospects.
