Solar intelligent control system

Abstract

The invention discloses a solar intelligent control system. The system comprises a solar battery, a storage battery and a linear load, wherein a charging circuit is formed between the solar battery and the storage battery; an output circuit is formed between the storage battery and the linear load; a voltage sampler is also arranged between the anode and cathode of the solar battery; the output end of the voltage sampler is connected with a PLC (programmable logic controller); the PLC is connected with a booster circuit; the booster circuit is arranged between the solar battery and the voltage sampler; an on-off control unit is arranged on the output circuit; the PLC controls on / off of the linear load by the on-off control unit; the control system also comprises a commercial power supply; another output circuit is formed between the commercial power supply and the linear load; and the commercial power supply is connected with the PLC. The solar intelligent control system realizes intelligent control of on / off of the linear load and has the advantages of low energy consumption, high reliability and the like.

Description

technical field [0001] The invention relates to the field of intelligent control, in particular to a solar energy intelligent control system. Background technique [0002] With the increasing shortage of energy and the improvement of energy conservation and environmental protection requirements, the linear loads in many cities currently use solar energy as their power supply, and the linear load controller controls the switching of the linear load. [0003] At present, the linear load controllers on the market mostly adopt the method of combining "time control" and "light control" in the method of turning on and off the linear load, that is, according to different seasons, the time setting button on the controller is manually operated. It is very inconvenient to use this method to adjust the light time of the switch, and because the weather is unpredictable, turning on and off the lights at regular intervals sometimes does not achieve a good output effect. When it rains con...

[0003] At present, the linear load controllers on the market mostly adopt the method of combining "time control" and "light control" in the method of turning on and off the linear load, that is, according to different seasons, the time setting button on the controller is manually operated. It is very inconvenient to use this method to adjust the light time of the switch, and because the weather is unpredictable, turning on and off the lights at regular intervals sometimes does not achieve a good output effect

When it rains continuously for many days, the power stored in the battery cannot meet the power consumption of the street lamp at night, causing the street lamp to not work normally

[0004] The existing solar controller, when the solar cell receives sunlight, can only be charged when the generated voltage is greater than the battery voltage, and stops charging when the voltage is slightly lower than the battery voltage, so the charging capacity of the battery is insufficient to meet the power consumption of street lamps.
