Self-boosting wind and light complementation solar energy street lamp controller

Abstract

The invention relates to a self-elevating wind and light complementation solar energy street lamp controller, comprising a boost circuit, a wind generator charging circuit, a charge unloading circuit, and a storage battery reserve detecting circuit. A working condition of the controller can be set based on function setting keys. Information sampled by a storage battery reserve sampling circuit is transmitted to a P012 pin of a microprocessor PIC, to analyze and determine a present reserve state of the storage battery. Intelligent control is realized by using the PIC microprocessor to program special software of the controller. The controller of the invention not only can effectively prolong lighting time in adverse climate and service life of a lead acid storage battery, but also can improve charging efficiency and charging quality, can reduce cost, and is easily popularized in the market.

Description

technical field [0001] The invention relates to a self-elevating wind-solar complementary solar street lamp controller. Background technique [0002] Solar cells can receive sunlight during the day and convert light energy into electrical energy. The wind turbine generates electricity through the action of the wind, and charges and stores it through the battery, and supplies solar street lighting at night. Application No. 200810058103.8 Chinese Invention Patent "PWM Charging Light Control Timing Dual Output Solar Street Light Controller:", including charging and lighting circuits composed of solar cells, storage batteries and lamp holders. The solar cells in the system are connected through a combination of MOS The field effect transistors Q5 and Q6 are connected in series with the same polarity of the battery, and the PO.0 and PO.1 ends of the microprocessor PLCC-32 are connected to the corresponding MOS field effect transistors Q7 and Q8 through mutually symmetrical singl...

Problems solved by technology

However, the four-bit BCD dial switch is used to mechanically set the lighting time of the two road lights, so the over-discharge protection of the lead-acid battery cannot be realized, resulting in serious over-discharge of the lead-acid battery to cause vulcanization, destroying the organizational structure of the lead-acid battery, and reducing the battery life. service life

At present, the wind-solar hybrid solar street lamp controllers sold on the market also have the following disadvantages: when the wind speed of the wind turbine does not reach the charging cut-in point of the controller, the wind-driven generator runs without charging, and when it reaches the cut-in point, it will be charged with high power. , so that the charging phenomenon cannot meet the requirements of PWM charging
