Intelligent control system, intelligent control device and intelligent control method for solar street lamp

Abstract

The invention discloses an intelligent control system, an intelligent control device and an intelligent control method for a solar street lamp. The method comprises the steps: acquiring the dischargecapacity, the charge capacity and the remaining capacity of a battery pack in each period; judging the state information of the battery pack according to the discharge capacity and the charge capacityof the battery pack in the current period; obtaining environmental parameters of a next period, taking the environmental parameters as first input variables to establish a charging power model function; estimating the charging power of the battery pack in the next period; taking the residual electric quantity of the battery pack, the state information of the battery pack and the charging power ofthe battery pack in the next period as second input variables, and performing modeling to estimate the allowable discharge capacity of the battery pack; according to the discharge capacity allowed bythe battery pack, controlling the illumination power of the LED lamp in the next period. The solar street lamp can be accurately controlled, the electric quantity of the battery pack can be ensured to be available, insufficient illumination brightness of the solar street lamp caused by insufficient electric quantity of the battery pack is avoided, and the illumination requirement of a road is met.

Description

technical field [0001] The invention relates to the technical field of solar street lamp control, in particular to an intelligent control method for solar street lamps, an intelligent control device for solar street lamps and an intelligent control system for solar street lamps. Background technique [0002] LED solar street lights use solar energy as energy. During the day, solar panels convert solar energy into electrical energy to charge solar lithium batteries, store electrical energy, and use solar lithium batteries to power LED lights at night to meet road lighting needs. [0003] The current LED solar street lights usually use automatic switching to meet the lighting needs. During the lighting period, the street lights work with the same power. Since the solar energy itself generates very limited power, this method is easy to cause the limited electric energy not to be fully utilized. , which leads to energy waste, the energy saving effect is not ideal, and even affec...
