Shown in Fig. 1～4, the utility model be a kind of solar energy pulse towards the formula charging system, it comprises:
One solar panels 10 are as the electric power source of system.
One charging system 20, charging system 20 has a battery 21, battery 21 starts 23 bindings in parallel with a photo resistance 22 and a charging respectively, photo resistance 22 is connected with a variable resistor 24 in addition, and charging system 20 has one first electric crystal switch 25 in addition, charging system 20 links with solar panels 10, charging system 20 can maximal efficiency acquisition and stablize the electric power source program that solar panels 10 are provided, and be stored in the battery 21, and charging system 20 links a controller 30 and a flyback circuit 40 in addition, the control that controller 30 can charge via the first electric crystal switch 25 and 23 pairs of charging systems 20 of charge switch, and flyback circuit 40 can provide power supply, and each power supply has ground reference separately.
The one widely different voltage-stabilizing system 50 of awarding, the widely different voltage-stabilizing system 50 of awarding has one the 2nd IC51, and the 2nd IC51 can detect the voltage of load 70, and 40 loads 70 with the back level of control flyback circuit reach the voltage stabilizing state.
One loop start circuit 60, the voltage signal that loop start circuit 60 can utilize the photo resistance 22 of charging system 20 to be detected, convert frenquency signal to through an IC32, loopback gives the single-chip 31 of controller 30, make the action of single-chip 31 Control Circulation start-up circuits 60, to award voltage-stabilizing system 50 and flyback circuit 40 carries out start-up control to widely different.
As shown in Figure 3, controller 30 employed formulas are to define earlier memory body respectively, buffer, and the enabling counting device, and wait for when counter makes zero that making it overflow interrupts, and judge whether to interrupt into detecting A/D photo coupler formula, if then judge earlier to enter evening on daytime, otherwise judge whether again to enter daytime in evening.
If daytime is when entering evening, at first the photo resistance 22 of charging system 20 can feel whether the photometry degree reaches the standard darkness of start-up circuit, if have, then an IC32 of controller 30 can be with the voltage signal of photo resistance 22, be converted to frenquency signal, and voltage signal is sent in the single-chip 31 of controller 30, and utilize the motion flow of the formula control circuit of single-chip 31, driving loop start circuit 60 triggers, make the capacitance energy storage in the loop start circuit 60, ordering about the 2nd IC51 starts, make it flyback circuit 40 is sent pulse-width modulation (Pulse Width Modulation the is called for short PWM) waveform of keeping 3 seconds, make closed stabilized switch 42 open, this can award voltage-stabilizing system 50 and flyback circuit 40 carries out start-up control to widely different, at this moment, 70 of loads are activated simultaneously, charging system 20 will stop action simultaneously, and when battery 21 supply flyback circuit 40 resupply the voltage decline of load 70, widely different the 2nd IC51 of voltage-stabilizing system 50 that awards is because of detecting the deficiency of load voltage, can carry out the widely different voltage stabilizing action of awarding to flyback circuit 40, make the coil of flyback circuit 40 inside increase energy storage, make it to boost, to continue that stable voltage source is supplied with in load 70.In addition, when the not enough 11V of the voltage source of the battery 21 of charging system 20, then the second electric crystal switch 41 of 31 pairs of flyback circuit 40 of single-chip of controller 30 is sent a high voltage ON signal, so that make closed stabilized switch 42 close, make no longer supply load 70 voltage sources of main circuit, and the single-chip 31 of sustainable supply controller 30 only makes controller 30 not have the anxiety of outage, to guarantee the normal running of system.
