In the time that battery tension drops to 9V, VZ1 cut-off, A point voltage is negative, VT1 forward conduction, by C2, V2 controlsExtremely controlled signal. The anodal lotus of charging of C1 is added on V1 negative electrode through V2, makes V1 negative electrode moment add backward voltage and end, defeatedGo out to hold Non voltage output, Red LED1 LED2 extinguishes, and yellow LED 1 is lighted, pilot cell undertension. ThisSample has just completed protection battery overdischarge phenomenon. 2) charge protector and indicating circuit
Solar photovoltaic assembly is as charge power supply, and this circuit is direct current 12V electric power system. When battery tension is charged to, VZ2 punctures conducting when 13.5V the left and right, and B point current potential is being for just, the reverse-biased cut-off of VT3, and D0l conducting, and trigger V4 conducting. The anodal institute of C3Charging lotus is added on V3 negative electrode through V4, makes that V3 is instantaneous to be added backward voltage and end, and turn-offs charging potential source.

When cell voltage is during less than or equal to 13V,VZ2 cut-off, the conducting of VT3 positively biased, electric current triggers V3 conducting through C3, and charge circuit is communicated with again, and C3 is also charged simultaneously. When finding to oweWhile pressing indicator lamp bright, should charge the battery. When red led is bright, represent cell voltage abundance, can normally use.

The operation principle of light-operated circuit and time control circuit is:
555 time base circuit IC1 are connected into the adjustable astatic multivibrator of dutycycle. When after unglazed photograph, K0-1--1 closure,Timing circuit is connected battery 12V dc source, and meanwhile, K0-0-1 opens, and has cancelled the short circuit to C2. Due to capacitor C2Powering up transient voltage can not suddenly change, and 2 pin that make IC2 circuit are low level, and IC2 circuit is in SM set mode, and 3 pin outputs are highLevel, relay K 1 is worked, contact K1-1-1 closure, the break-make of constant current driving power supply circuits is controlled in its contact, reaches and controls LEDThe effect of light fixture. IC1 time base circuit starts to form vibration simultaneously, and therefore 3 pin are alternately exported high and low level. When 3 pin are exported highWhen level, logical R4 charges to capacitor C02. In the time of 3 pin output low level, C02 does not charge, and can pass through on the contrary R4(150K) there is electric discharge a little. Therefore only in the time that being high level, 3 pin just C02 is charged, so the charging interval of capacitor C02Longer. Setting-up time arrives, and when the current potential of capacitor C02 is raised to 2/3VDD, IC2 time base circuit resets, and 3 pin output low levels, continueElectrical equipment K1 dead electricity, contact K1-1-1 disconnects, and LED light fixture extinguishes because of its driving power power-off, plays lighting time and controls. CauseFor, working all the time at KO at dark, K0-1-1 is adhesive all the time, and timing circuit has all the time supply voltage and is in running order.
In debugging, the resistance that changes resistor RP by toggle switch S changes 555 time base circuit IC1 the 3rd pinsThe dutycycle of output square-wave pulse, thereby the timing of change timer. This timing circuit is the highest can set timingTens of hours.
Described constant-current drive circuit comprises capacitor C in, inductance L, diode DS, chip MT7202, resistance R sns, electric capacityCled, one end of described capacitor C in connects the normally opened contact K1-1-1 other end of relay K 1, and the other end of capacitor C in is respectivelyConnect the anode of one-way SCR V1 and the second pin of chip MT7202, the first pin of chip MT7202 connects respectively inductanceL one end and diode DS positive pole, another termination of inductance L LED light fixture negative pole, diode DS negative pole connects respectively chip MT7202Five pins and resistance R sns one end, the resistance R sns other end connects respectively chip MT7202 the 4th pin and LED light fixture positive pole, electric capacityThe two ends of Cled connect respectively the positive and negative electrode of LED light fixture.
The operation principle of constant-current drive circuit is:
The composition constant-current drive circuit taking MT7202 integrated circuit as core. The size that changes Rsns can change constant current outputElectric current. When monolithic MT7202 uses in 12V solar illuminating system, maximum can drive the LED lamp of 15W. Be used in 24V systemPower can double.
The course of work of whole controller:
Daytime is while having illumination, and solar panel has photovoltaic Voltage-output → through light-operated circuit D02 → R09 → VT4 base stage,VT4 saturation conduction, VT5 cut-off, often open → timing circuit of be failure to actuate → K01-1 of K0 power supply is cut off and can not work → K1Do not work, often open → constant-current driving power supply of K1-1-1 is cut off can not work → LED light fixture and does not work. During this, constant-current sourceDrive circuit, timing circuit power circuit are cut off, K0 does not work, and controller system electrical loss is very little.
Darkness is unglazed according to time, solar panel does not have photovoltaic Voltage-output, light-operated circuit VT4 base stage is without bias voltage,VT4 cut-off, VT4 colelctor electrode high potential → VT5 saturation conduction → K0 work → K01-1 closure → timing circuit power connection, start working → K1 of timing circuit work → K1-1-1 closure → constant-current driving power supply is connected and work → LED lamp is lighted.After timing arrives, K1 quits work, and LED lamp extinguishes.
The above is only the preferred embodiment of this patent, it should be pointed out that the ordinary skill people for the artMember, not departing under the prerequisite of the art of this patent principle, can also make some improvement and replacement, these improvement and replacementAlso should be considered as the protection domain of this patent.
