Problems solved by technology

However, there are still many deficiencies in the current lighting control system, and it is not yet possible to achieve intelligent control of lighting equipment.
The traditional street light control system has the following disadvantages: 1. Time setting is used to control the lighting on and off. Once the setting is completed, it cannot be modified, so unnecessary lighting is caused in the middle of the night when there are few people's activities; 2. , Generally, the mains power supply is used, and the existing energy is not effectively used, so the current street lamps all have energy waste.
[0003] According to statistics, there are basically no vehicles passing by on the roads in many residential areas after zero o'clock, but the street lights in the community are still on, and the lights are not turned off until the set time of the next day, resulting in serious energy waste. The temperature of the chip rises, and the LED is on for a long time, so the LED lamp is in a state of temperature rise for a long time. Due to the high temperature, the photons emitted by the chip will decrease, the quality of the color temperature will decrease, the aging of the chip will be accelerated, and the device will be shortened. life expectancy and other serious consequences

Abstract

The invention discloses an LED street lamp intelligent control system. The control system comprises a lampshade and a lamp plate. Two LED lamp groups arranged in an annular manner are distributed on the lamp plate. The first LED lamp group is arranged outside the second LED lamp group in an annular manner. A signal collection circuit is connected with a one-chip microcomputer through a signal conversion circuit. The commercial power goes through a voltage stabilization module and a switching circuit in order and is connected with the first LED lamp group. The voltage stabilization module is connected with a storage battery through a switch circuit. The switch circuit is in signal connection with the one-chip microcomputer. A solar energy charging panel is connected with the storage battery. The storage battery is connected with the switching circuit. The storage battery is in signal bidirectional intercommunication connection with the one-chip microcomputer. The one-chip microcomputer is controlled by a relay and is connected between the switching circuit and the first LED lamp group. The one-chip microcomputer is connected with the LED lamp group through a PWM light modulation drive circuit. The one-chip microcomputer is connected with the second LED lamp group through a relay control circuit. Brightness of street lamps is controlled through detection of vehicles or pedestrians to achieve energy saving effects. Energy saving effects are achieved through bidirectional power supply of solar energy power supply and commercial power. Main lamps and auxiliary lamps work alternatively, and the working service life is raised.

Description

technical field [0001] The invention relates to an intelligent control circuit, in particular to an intelligent control system for LED street lamps. Background technique [0002] At present, energy saving and emission reduction is a major measure to implement the scientific outlook on development and build a harmonious socialist society. Energy saving and emission reduction is extremely important and far-reaching for adjusting the economic structure, changing the growth mode, improving the quality of life of the people, and safeguarding the long-term interests of the Chinese nation. significance. Street lighting in the community is a large user of the power system in the community, and there is a lot of room for energy saving. Therefore, LED street lamps have become the best choice for energy-saving renovation of road lighting with energy saving and environmental protection. However, there are still many deficiencies in the current lighting control system, and the intellig...
