Brightness control method and system for street lamp

Abstract

The invention discloses a brightness control method and system for a street lamp. The method comprises the steps of obtaining the unit time charge quantity of a battery within first preset time of employing to-be-controlled time as a time end and the unit time discharge quantity of the battery within second preset time before the to-be-controlled time; calculating the average charge quantity within the first preset time according to the unit time charge quantity within the first preset time; calculating the average discharge quantity within the second preset time according to the unit time discharge quantity within the second preset time; and controlling the brightness of the street lamp at the to-be-controlled time according to the magnitude relationship between the average charge quantity within the first preset time and the average discharge quantity within the second preset time, wherein the length of the first preset time is equal to that of the second preset time. According to the brightness control method and system for the street lamp, the problems that the battery is aged in an accelerated manner and the street lamp often cannot normally work due to performance degradationof the battery in the using process and continuous sunless weather can be solved.

Description

technical field [0001] The invention relates to the technical field of street lamps, in particular to a brightness control method and system for street lamps. Background technique [0002] The initial installation conditions of solar street lights are generally based on the lighting duration and power requirements of the actual needs of users to match the batteries and solar panels. Under normal lighting conditions, solar street lights can fully meet the requirements of use. Since solar street lights rely entirely on the sun to provide energy, the seasonal weather conditions caused by the local geographical location directly affect the use of street lights. The charge and discharge settings of solar street lights are generally based on the existing storage capacity of the battery to roughly estimate how much brightness to use for discharge. Under extreme weather conditions (for example, 5 consecutive days of rainy days), the charge and discharge settings of solar street lig...
