The authentication password can be an encrypted signal or a combination of different signals, but not a simple pulse, so that the authentication password cannot be cracked by a cracking technology of a small black box. The safety of the door lock is improved.

The power connection line is used for connecting a power supply, the signal connection line is used for connecting each sensor and receiving input signals, and one trigger signal connection line is used for transmitting wake-up signals and waking up the circuit control module 20 to work.
The circuit control module 20 includes: the boost chip 21, the boost chip 21 may be: SLM6800, MT3608, ME2108C40M 5G; the voltage stabilizing chip 22, the voltage stabilizing chip 22 may be: SPX3940AM3, XC6201P332MR, AMs 1117; a processor chip 23, wherein the processor chip 23 may be: STM32L051C8t6, STM8L152C6, ATMEGA169 PA; a motor driving chip 24, wherein the motor driving chip 24 may be: LV8549MC-AH, LGM9680, DRV8832 DGQ. As shown in the schematic diagram of fig. 2, the boost chip 21 is connected to the power supply 11 through a power connection line, and converts the voltage of the power supply 11 into a predetermined value for output, the voltage regulation chip 22 is electrically connected to the output end of the boost chip 21, the voltage regulation chip 22 converts the input voltage into a stable voltage for output, and the output end of the voltage regulation chip 22 is respectively connected to the main bolt sensor 40, the inclined bolt sensor 50, and the reverse bolt sensor 60; the processor chip 23 is electrically connected to the output end of the voltage stabilizing chip 22; the motor driving chip 24 is electrically connected to the output end of the voltage stabilizing chip 22, so that the voltage stabilizing chip 22 outputs a stable voltage to the main bolt sensor 40, the inclined bolt sensor 50, the reverse bolt sensor 60, the processor chip 23 and the motor driving chip 24. The output end of the motor driving chip 24 is electrically connected to the motor clutch driving module 30. The electric energy in the power is input into chip 21 that steps up, steps up through chip 21 that steps up, reaches the voltage requirement of each part, and rethread steady voltage chip 22 filters input end power change or undulant, makes the voltage stability of exporting each part, can guarantee the inside stable power supply of circuit control module 20 and the stable power supply to each sensor like this to make the electronic lock can the steady operation. And the voltage stabilizing chip 22 stably supplies power to the motor driving chip 24, so that the motor driving chip 24 stably supplies power to the motor clutch driving module 30, and thus the motor clutch driving module 30 provides stable driving power moment for the lock body when the lock is opened and closed.
One specific way of supplying power is: in order to ensure reliable driving torque output of the motor clutch driving module 30, the motor clutch driving module 30 includes a motor 31, when the voltage of the power supply supplied by the door lock is lower than 12V, the voltage boosting chip 21 boosts the low voltage to 12V and outputs the boosted voltage to the voltage stabilizing chip 22, and the voltage stabilizing chip 22 filters the power supply variation or fluctuation at the input end to ensure the stable voltage of 12V, thereby ensuring the stability of the working voltage of the motor 31.
As shown in fig. 1, the motor clutch driving module 30 further includes: an actuator 32, and a push plate sensor 33. The motor 31 is electrically connected to the motor driving chip 24 and receives a driving signal sent by the motor driving chip 24; the actuator 32 is mechanically connected with the motor 31 and moves through the rotation of the motor 31; the push plate sensor 33 is electrically connected to the processor chip 23, and the push plate sensor 33 sends a signal to the processor chip 23 when the actuator 32 moves.
The motor 31 is connected with the motor driving chip 24 through a wiring port, and receives a driving signal output by the motor driving chip 24, so that the motor 31 rotates to drive the mechanical movement of the actuating mechanism 32; the processor chip 23 receives the output signal of the push plate sensor 33, thereby determining whether the actuator 32 accurately executes the signal instruction of the driver chip, and realizing the closed-loop determination of driving and position detection. Therefore, the accurate intelligent control of the power and execution mechanism 32 can be realized, and the stability of the execution action of the door lock is ensured.
The motor 31 is a stepping motor, and the control signal output to the stepping motor by the motor driving chip 24 is a square wave driving signal. Like this, can improve the security of lock, in prior art, the drive of motor 31 just can realize rotating through one section signal pulse, adopts "little black box" to exert lasting pulse for motor 31 like this, just can drive motor 31 and rotate, just can crack easily and unblank. And adopt square wave drive signal in this scheme, be one section signal, the lock can only confirm the motion mode of this square wave signal driven motor 31 in addition and just can unblank, and other signal drive motor 31's motion modes can not unblank, just so can avoid "little black box" to disturb the lock through the pulse, improve the factor of safety of lock.
The confirmation process of the way that the door lock performs the square wave signal driving on the motor can be realized in various ways, such as directly setting a motor circuit which can perform the square wave signal but cannot perform the continuous pulse signal. Or the rotating speed of the motor is detected to determine whether the signal is an executed square wave signal, the square wave signal enables the motor 31 to operate for one section and stop for one section, the rotating speed is different from that of the continuous pulse, and the safety problem of the door lock is judged through the processor chip 23 after the different rotating speeds are sensed. Or the retraction time of the main bolt is sensed by main bolt sensor 40, the same driving stroke of normal square wave signal driving motor 31 is longer than the time of continuous pulse driving motor 31, if the retraction time of the main bolt sensed by main bolt sensor 40 is faster than the predetermined time, processor chip 23 can also judge that the safety problem of the door lock occurs.
As shown in fig. 1, the circuit control module 20 further includes a triggering dormant module 25, and the triggering dormant module 25 is electrically connected to the circuit main control module 10, the main bolt sensor 40, the inclined bolt sensor 50, and the anti-bolt sensor 60 through a triggering signal connection line; the sleep triggering module 25 receives the signal and wakes up the processor chip 23 in the sleep state. To conserve power, the processor chip 23 and other functionality such as storage, display, etc. are in a non-powered sleep state when the door is in a normally closed or normally open state. The sensor for identifying the identity on the circuit main control module 10 senses the user, and transmits a signal to the dormancy triggering module 25 after the identity of the user is identified by the circuit main control module 10, the dormancy triggering module 25 wakes up the processor chip 23, and the processor chip 23 starts to work, so that each function of the door lock is restored to a normal working state. Or when the door lock is normally unlocked by the key, each sensor senses the action of each bolt of the door lock, and a trigger signal can be sent to the processor chip 23 through the trigger signal connecting line to wake up the processor chip 23 to start working.

When the magnet 72 approaches the gate magnetic sensor 71, the gate magnetic sensor 71 is triggered to output a high level or low level signal; the processor chip 23 judges the opening and closing state of the door by collecting the high level or low level signal of the door magnetic module sensor. When the door magnetic sensor 71 of the door magnetic module and the magnet 72 installed on the door frame are out of the normal working range, and the processor chip 23 receives the signal of the door magnetic sensor 71, the processor chip 23 checks and judges that the legal unlocking instruction authorization of the circuit main control module 10 is not received in the processor chip 23, that is, the circuit main control module 10 does not identify the identity of the user, so as to judge the state that the door lock is illegally opened, and the processor chip 23 reports and outputs the intrusion alarm signal. Thereby effectively improving the safety of the door lock. Another illegal determination method may be: the door lock can be judged to be in an illegal unlocking state without unlocking through the key and executing the correct induction sequence of each inductor in the key unlocking. Or the processor chip 23 stores and executes the command of locking, and the door magnetic sensor 71 of the door magnetic module is separated from the magnet 72 mounted on the door frame, so that the state that the door lock is illegally opened can also be judged.
The main bolt sensor 40 includes an extension end detector 41 and a retraction end detector 42, the extension end detector 41 is disposed at the extension end of the main bolt, and the retraction end detector 42 is disposed at the retraction end of the main bolt; the extension end detector 41 senses and outputs a main bolt extension state signal when the main bolt extends; the retraction end detector 42 senses and outputs a main bolt retraction status signal when the main bolt is retracted. By adopting the scheme, the extension end detector 41 and the retraction end detector 42 of the main bolt are respectively arranged, the state detection of the main bolt is more accurate, the main bolt is normally unlocked and locked in the extension and retraction states, the state of the door lock can be accurately monitored by accurately controlling the state of the main bolt, and the stable state of the door lock is ensured.
