The working principle of the low-power consumption Bluetooth lock control module circuit is as follows: the whole circuit is in a long-term working state, a lithium battery BT (storage battery) with the voltage of 1600mA provides a 4V power supply, the lithium battery BT is charged through a charging boosting chip IC2, and when the power supply is output, the voltage of the 4V is boosted and stabilized to 5V through the IC2 for the MOTOR of the lock tongue, unlocking and the electric quantity indicator lamp to work (the 8 pin of the IC2 is an output pin which is boosted to 5V, and the 3 pin is a boosting loop ground); the voltage is reduced to about 3.5V by D3 to supply the extra-gate circuit to operate. In the standby state, the whole circuit only works in the sleep state by the low-power consumption Bluetooth module, and the power consumption is extremely low.

The low-power-consumption Bluetooth module IC1 in the outdoor circuit is written with a control program which interacts with the Bluetooth lock APP, and is a control element of the low-power-consumption Bluetooth lock control module. When the setting key S3 is pressed, the pin B6 of the low-power Bluetooth module IC1 is enabled to be low, the IC1 enters a setting program, the pin B11 is enabled to be low, and D2-r is lightened; when the unlocking key S1 is pressed, the B3 pin of the IC1 is enabled to be in high level, the IC1 enters an unlocking program, after the identity and the password are verified to be correct, the IC1 drives the lock tongue motor to rotate positively and negatively through the B7 pin and the B8 pin, and the locking action is carried out by opening or closing, and the process is as follows: in the standby state, pins B7 and B8 are in low level, switching triodes Q1 and Q2 are cut off, relays K1 and K2 do not work and are in a normally closed state, and voltages at two ends of a MOTOR MOTOR are equal and do not act; when the lock is opened, the IC1 is set at a high level of a B7 pin, the Q1 is conducted, the K1 works, the normally-open contact B is switched on, current falls to the ground from the normally-closed contact A of the K2 through the normally-open contact B of the motor at the K1, the motor rotates for 150mS positively, the lock is opened, then the B7 pin is set at a low level, and the standby state is temporarily restored; the IC1 controls unlocking time for 4 seconds, then B8 is placed at high level, Q2 is conducted, K2 works, a normally open contact B is grounded, current passes through a normally open contact A of the motor at the K2 from a normally closed contact A of the K1 to fall to the ground, the motor is reversed for 150mS, a lock is closed, then B8 is placed at low level, a standby state is restored, and unlocking is completed.

The unlocking indicator light and the electric quantity indicator light are combined into a whole. In this circuit, since the voltage boosted by IC2 is relatively stable, a reference voltage is introduced from pin 8 of IC2, and two comparison voltages of 3.3V and 3.7V are separated by R4 and R5, and are compared with the output voltage of BT by U1A, U a. When the voltage of BT is larger than 3.3V, the U1A is turned on to turn on D2-g, otherwise, D2-g is turned off; when the voltage of BT is greater than 3.7V, U2A is turned off to extinguish D2-r, and otherwise D2r is turned on. Thus, when the electric quantity of the BT is reduced from high to low, the indicator light is changed from green to red. The IC1 sets the B10 high level while setting the B7 pin high level, Q3 is conducted to enable unlocking and electric quantity indicating lamp circuits to work, and an indicating lamp is lightened; when the IC1 sets the high level of the pin B8, the pin B10 is set to be high and low, so that the Q3 is cut off, and the indicator light is turned off.

The switch S4 is a limit switch, and the function of the switch S4 is mainly used for enabling the inner lock shell and the outer lock shell to displace when the outer shell of the lock is damaged, enabling the S4 to act to cut off the power supply, enabling the whole circuit to be disabled, preventing the lock tongue motor from being driven by the outgoing line outside the door, preventing the outgoing line from being used for reversely supplying power outside the door, and simultaneously reducing 4V power supplied by BT to about 3.5V for the circuit outside the door.
