Control system and control method of lithium cell type solar LED street lamp

Abstract

The invention relates to a control system and a control method of a lithium cell type solar LED street lamp. The control system comprises a solar cell panel, a power supply lithium cell assembly, a brightness-adjustable LED lamp, a constant-current dimmer and an intelligent controller. The solar cell panel, the power supply lithium cell assembly and the constant-current dimmer are connected with the intelligent controller. The brightness-adjustable LED lamp is connected with the constant-current dimmer. The intelligent controller comprises a control mainboard, a cell panel management module, a lithium cell management module and an LED lighting driving module. The LED lighting driving module is connected with the control mainboard. The power supply lithium cell assembly comprises a lithium cell set, a cell protecting board, a constant-temperature control board and a heating board. The lithium cell set, the constant-temperature control board and the heating board are connected with the cell protecting board. The cell protecting board is connected with the intelligent controller. According to the control method, one or a set of lighting curves is generated through the intelligent controller according to a user decision table, and furthermore a certain lighting curve is selected for performing dimming on the brightness-adjustable LED lamp, thereby satisfying a road requirement of a user.

Description

technical field [0001] The invention relates to a street lamp lighting control system, in particular to an LED street lamp intelligent control system with solar power generation and lithium battery energy storage and a control method thereof. Background technique [0002] Street lamps are the most common urban public lighting infrastructure, and they are also major power consumers in cities. In response to the country's call for energy conservation, emission reduction and low-carbon life, solar street lamps are often used on newly built roads, combined with solar batteries to store electricity. Street lights are powered independently. The selection of a battery usually requires the battery to have the characteristics of many cycle charging times, high capacity and long life. However, due to the consideration of the cost and price of street lamps, most of the special batteries for solar street lamps use conventional low-priced lead-acid batteries, and their service life is s...

Problems solved by technology

The control methods of these control systems are not humane enough. At the same time, the lights are completely turned off, and the road is dark, which is even more detrimental to road safety.
