Fig. 3 is the schematic flow sheet of control method of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
With reference to Fig. 1, the present invention mainly is comprised of solar cell, controller, storage battery, mains-supplied and load LED street lamp, and wherein solar cell is used for solar energy is converted to electric energy, and solar cell charges a battery by day.Storage battery be the deposit energy device, evening or overcast and rainy be system and load LED street lamp power supply, road lamp power supply; Controller is electrically connected to respectively at solar cell, storage battery, mains-supplied, load LED street lamp, and storage battery is electrically connected to solar cell, mains-supplied respectively;
Controller is of paramount importance parts in Solar Street Lighting System.Controller mainly is comprised of voltage detection module, accumulator cell charging and discharging module, handover module, power module, reseting module, clock module.The STM8 single-chip microcomputer that in the embodiment of the present invention, the French ST of employing company produces is controlled the LED Solar Street Lighting System.The voltage judgement of controller by detecting the solar cell two ends be according to sun brightness, daytime disconnecting consumers LED street lamp and charging a battery, evening by storage battery to load LED street lamp power supply, road lamp power supply.And according to judging whether surpass 12 realizations in evening and carry out at times the power adjustment time in the evening.When the storage battery quantity not sufficient, automatically switch to the mains-supplied system.
With reference to Fig. 2, realize that by controller daytime, solar cell charged a battery, evening or cloudy day, for load LED street lighting, are realized environment protecting and power-saving.In the present embodiment, storage battery charge control circuit adopts chopped mode PWM charging principle, and at first controller detects the both end voltage of storage battery, and compares with predefined magnitude of voltage, and then selects different charging modes.
In way, wherein J1, J3 are respectively the positive pole of storage battery and solar cell, controller is sampled to solar array voltage and battery tension respectively by R20, R21 and R18, R19, through AD conversion judgement, meeting charging or stopping under charge condition, single-chip microcomputer P0.3 mouth provides charging control signal, makes triode S conducting or cut-off, can realize charge in batteries, concrete visible programming part.Wherein in figure, D6 is the anti-reverse charging Schottky diode, avoids when battery tension during higher than solar array voltage, and storage battery is to the solar cell reverse charge.D7 is a protection diode, and when reverse connection of accumulator, circuit disconnects, protection storage battery, the reliability of raising system.
With reference to Fig. 3, the control method of the embodiment of the present invention comprises following concrete steps:
Steps A: controller self check current state, whether according to the voltage detecting at solar cell two ends, judge current is daytime,
Step B: if be, storage battery is entered to charged state, and further according to the current voltage value judgement at storage battery two ends, select different charge modes,
Step B1: if when the current voltage at storage battery two ends is greater than over-charge protective voltage, automatic charge closing switch;
Step B2: if, when the current voltage at storage battery two ends is less than over-charge protective voltage and is greater than recovery voltage, storage battery enters the state that directly fills, i.e. quick charge;
Step B3: if when the current voltage at storage battery two ends equals recovery voltage, enter the equalizing charge pattern;
Step B4: if, when the current voltage at storage battery two ends is less than recovery voltage and is greater than the Cross prevention final voltage, enter floating charge state, i.e. trickle charge;
Step B5: if when the current voltage at storage battery two ends is less than the Cross prevention final voltage, abandon charging;
Step C: if whether, storage battery enters discharge condition, and further according to the current voltage value judgement at storage battery two ends, selects different mode of operations,
Step C1: if, when the current voltage at storage battery two ends is less than protection voltage, controller switching is charged to mains-supplied;
Step C2: if the current voltage at storage battery two ends is more than or equal to protection voltage, further judge that whether the current time is over point in evenings 12, if surpass point in evenings 12, be communicated with two load LED street lamps, otherwise, be communicated with single load LED street lamp.
