The working process of the household multi-gear solar charger circuit of the embodiment is exemplified as follows: under illumination, the solar cell panel outputs corresponding voltage, and the voltage charges the storage battery through the charging control and regulation circuit and the charging protection circuit.
(1) First, according to a schematic circuit diagram (fig. 1), the relevant resistance and voltage parameter values required for the regulation are calculated. According to the capacity of the storage battery to be charged, the resistance values R of the resistors R5, R6 and R7 are calculated respectively, and the formula for calculating the resistance value R is as follows (1):
wherein: r is the resistance of R5, R6 or R7; BAT (BAT) Nominal value Is the voltage of the normal value of the BT of the storage battery, I max Is the maximum current value in the circuit, i.e. the short-circuit current of the solar panel, i.e. 500mA.
(2) The potentiometer R4 in the circuit is then adjusted, i.e., the input voltage to the TL431AC chip input pin (reference voltage terminal R) is adjusted until the TIB30B is turned on. The formula for calculating the resistance value of the variable resistor Rx is as follows formula (2):
wherein Rx is a partial value of a potentiometer R4 (variable resistor), BAT max Is the maximum voltage value of the battery BT (i.e. the voltage when the battery is fully charged), V input-TL431AC Is the TL431AC chip input voltage equal to2.5V, R3 has a resistance of 1.5KΩ and R4 has a resistance of 20KΩ.
(3) And the storage battery BT to be charged is connected, different gears are selected according to the capacity of the storage battery to be charged, and the storage battery mainly comprises storage batteries of 5V, 12V and 24V. If the storage battery is 5V and 12V, a single solar panel (the open circuit voltage is 18V) can be used to shift the single-pole double-throw switch SW1 to the 2 position (namely the movable end 1 of the single-pole double-throw switch SW1 is connected with the stationary end 2), and if the storage battery is a 24V storage battery, two panels are required to be connected in series to shift the single-pole double-throw switch SW1 to the 3 position (namely the movable end 1 of the single-pole double-throw switch SW1 is connected with the stationary end 3). At the same time, the knob switch SW2 is also changed. When the battery is 5V, the knob switch SW2 rotates to the 7 position (namely, the movable contact 4 of the knob switch SW2 is communicated with the third fixed contact 7), when the battery is 12V, the switch SW2 rotates to the 6 position (namely, the movable contact 4 of the knob switch SW2 is communicated with the second fixed contact 6), and when the battery is 24V, the switch SW2 rotates to the 5 position (namely, the movable contact 4 of the knob switch SW2 is communicated with the first fixed contact 5), so as to adapt to different charging voltages and avoid burning.
(4) After the circuit is connected, current flows out of the solar panel and charges the storage battery through the IN5818 Schottky diode.
(5) Over time, the voltage across the battery increases, and TIP30B turns on when the battery reaches the float setting and also reaches the input voltage regulation point of TL431AC (i.e., reaches the voltage at which TIP30B turns on).
(6) The TIP30B is conducted, and the charging protection circuit consumes all solar energy electric quantity, because the TIP30B is connected with the resistor of R5, R6 or R7 to two ends of the solar panel, excessive charging current can be transferred to the R5, R6 or R7 load resistor so as to keep constant voltage, and part of energy is consumed, so that the charging and overcharge protection functions are realized; at this time, the solar power source consumed by the charging protection circuit generates heat, and heat dissipation is accelerated by installing the radiating fins.
(7) When sunlight is offset, the voltage output by the solar cell panel is lower than the voltage at two ends of the storage battery, and the current of the storage battery is prevented from reversely flowing into the voltage stabilizing circuit due to the arrangement of the current reverse preventing protection circuit H, so that the effect of the protection circuit is achieved.

the motor control module receives the data transmitted by the microprocessor module, and controls the movement of the motor according to the condition of the data or the instruction so as to adapt to the change of illumination.
The specific cases are as follows:
(1) When the microprocessor works, a rotation instruction and a data acquisition instruction are sent to the motor control module at regular intervals (1 s), the values of illumination intensity and output voltage are acquired in real time, the values of illumination intensity and output voltage which are acquired currently are compared with the values of illumination intensity and output voltage at the last moment, the maximum value of the values of illumination intensity and output voltage is found out, and the fact that the solar panel is aligned with the sun in real time is indicated at the optimal position. Meanwhile, the maximum value of the values of the illumination intensity and the output voltage at different times in one day is saved, a set reference value is calculated, and the reference value is used as a standard value. This standard value will vary with the season or weather conditions. After a long period of operation, fixed reference and standard values are calculated.
(2) When the value of the illumination intensity and the output voltage on the solar panel received by the microprocessor module is larger than the preset standard value, the microprocessor module does not send any instruction to the motor control; at this time, the solar panel is aligned with the sun and no rotation is required.
(3) When the value of the illumination intensity and the output voltage on the solar cell panel received by the microprocessor module is smaller than the preset standard value, the microprocessor module sends a rotation instruction automatically following the sunlight receiving direction to the motor control module, so that the solar cell panel can be aligned to the sun in real time, the solar energy receiving power is improved, and the charging time of the battery is effectively shortened.
(4) When the illumination intensity and the output voltage on the solar panel received by the microprocessor module are close to zero, the microprocessor module sends an off-working instruction to the motor control module. At this time, if the storage battery is charged and not taken out in the daytime, the microprocessor module can send out an order of no work at night to prevent the motor control module from working, and the whole electric quantity of the storage battery can not be consumed because the working power consumption of the sensor is lower.
