Intelligent solar street lamp control system

Abstract

The invention discloses an intelligent solar street lamp control system in the field of solar street lamps. The intelligent solar street lamp control system comprises a power supply module, a collection unit and a control unit, wherein the power supply is connected with the control unit. The collection unit comprises a solar panel voltage collection module and a storage battery voltage collection module, the output end of the collection unit is connected with the input end of a singlechip through an analog-to-digital (A / D) convert circuit, the output end of the singlechip is connected with a display unit, the output end of the singlechip is further connected with the input end of a charge-discharge control module, and the output end of the charge-discharge control module is connected with a driving unit. According to the intelligent solar street lamp control system, electric quantity of a solar battery panel and a storage battery is detected to judge if the battery is in an over-charge or over-discharge state, control is conducted, and therefore the intelligence degree is improved, service life of the battery is prolonged, and the intelligent solar street lamp control system can be used in the solar street lamps.

Description

technical field [0001] The invention relates to a solar street lamp, in particular to a solar street lamp control system. Background technique [0002] In the past, due to the gradual maturity of photovoltaic technology, the cost has been falling, and solar energy is ubiquitous and inexhaustible, which makes solar energy companies face new opportunities. Various solar electronic products developed by using solar energy are developing very rapidly, such as: solar water heaters , solar street lamps, solar heat pumps, solar traffic lights, solar dehumidification air-conditioning systems, etc. These products have shown huge market potential and vitality. In lighting fixtures, as a combination of technology and art, solar street lights are street lights that use solar energy as energy. Compared with street lights powered by conventional energy, they have many advantages. Street lights can be installed anywhere, whether in remote mountain villages or cities, without connecting to...

Problems solved by technology

[0003] Its shortcoming is that when the sun is sufficient for a long time, the electric energy converted by the solar panels will be relatively sufficient, and the storage battery has a specified capacity. The increase will cause a large number of bubbles in the electrolyte, the water will evaporate too fast, the concentration of the electrolyte will exceed the normal value, the whole battery will heat up, the temperature will rise rapidly, the electrolyte loss of the plate will be accelerated, and the active material of the plate will fall off, which will shorten the life of the battery or scrapped

In long-term cloudy and rainy days, if the battery does not receive sufficient electric energy and generates electricity, over-discharge will occur. The internal pressure of the battery increases, and the reversibility of the positive and negative active materials is damaged, which significantly reduces the capacity of the battery.
