Street lamp control system for lighting up and down in the middle of the night

Abstract

The invention discloses a street lamp control system achieving brightness boosting and brightness reducing at midnight. The street lamp control system comprises a main controller, a timer, at least one optical sensor, a power controller and a historical database; the main controller comprises a midnight brightness reducing module and a midnight brightness boosting module; the midnight brightness reducing module is used for controlling a street lamp to be set to reduce the power of the street lamp in the first moment through the power controller, and the time for reducing the power of the street lamp is the start-up time of the street lamp in the current cycle plus 40%-50% of the turn-on duration of the previous cycle; the midnight brightness boosting module is used for controlling the street lamp to be set to increase the power of the street lamp in the second moment through the power controller, and the time for increasing the power is the first time of the current cycle plus 30%-40% of the turn-on duration of the previous cycle. According to the street lamp control system achieving brightness boosting and brightness reducing at midnight, the illuminating brightness of the street lamp can be controlled according to different time requirements.

Description

technical field [0001] The invention belongs to the technical field of street lamp control, and relates to a street lamp control system, in particular to a street lamp control system for turning on and off at night. Background technique [0002] With the advancement of technology, the control method of street lights is becoming more and more intelligent; street lights are usually controlled by a fixed duration, such as setting the lights to turn on at 6 o'clock in the evening and turn off the lights at 6 o'clock in the morning. However, this control method cannot be controlled for different weather conditions (such as rainy weather); at the same time, because the length of day and night is constantly changing, the method of controlling the lights on and off at a fixed time cannot meet the needs of pedestrians. [0003] Another control method is to set a light sensor to sense the light intensity through the light sensor, and switch the street light when it reaches a critical ...

AI Technical Summary

Problems solved by technology

Therefore, the current way of controlling street lamps through light sensors cannot well meet people's requirements.

[0004] In addition, the lighting intensity of street lamps in the existing control method is the same and cannot be changed according to the number of pedestrians
