Of course, in another embodiment, a third bluetooth module may be further included in the tag lock manager; the functions of the two Bluetooth modules can be realized through the three Bluetooth modules; namely, the first Bluetooth module is used for transmitting the Bluetooth broadcast of the fixed address code to a preset range in real time; the second Bluetooth module is used for scanning the state information of the seal lock within a preset range in real time, and when the state of the seal lock scanned by the second Bluetooth module is an unlocking state, the second Bluetooth module initiates connection to the seal lock and changes the state of the seal lock into a to-be-locked state; the third Bluetooth module is used for scanning the seal lock in the locking state, sending information such as the lock code of the seal lock, the lock unlocking state code and the address code to the communication modules such as WiFi or GPRS, and reporting the information such as the lock code of the seal lock, the lock unlocking state code and the address code to the background server through the communication modules such as WiFi or GPRS.

In addition, in an implementation manner, a fourth bluetooth module may be further disposed in the lock opener, and configured to establish a communication connection with the mobile terminal, receive an unlocking password sent by the mobile terminal, or send the received unlocking status code to the mobile terminal or the background server.

Of course, in another embodiment, a display screen (not shown) may be disposed on the surface of the lock housing, and the display screen is electrically connected to the first circuit board; the locking state of the seal lock can be displayed in real time through the display screen, the connection state with the server end can be displayed in real time, and the like; the display screen and the connection mode thereof are the prior art, and are not described herein.

Further, in another embodiment, a display screen (not shown) may be further disposed on a surface of the lock opener housing, and the display screen is electrically connected to the second circuit board; the locking state of the seal lock can be displayed in real time through the display screen, the connection state with the server end can be displayed in real time, and the like; the display screen and the connection mode thereof are the prior art, and are not described herein.

The working principle of the control system of the embodiment is as follows:

on one hand, firstly, the object of the seal is placed into the lock shell, and the size of the space between the adjustable clamping component arranged in the lock shell and the bearing component is adjusted, so that the objects with different volumes placed on the bearing component can be effectively clamped. For example, when an article to be sealed is placed on the bearing part and the volume of the article is small (such as a bag and the like), the length of the clamping part extending out of the clamping part is lengthened, so that the clamping part clamps the article on the bearing part, meanwhile, the bearing part presses the first travel switch due to the weight of the article, the first circuit board receives a closing signal of the first travel switch, and the article to be sealed on the bearing part is judged; then, the first gear set is driven to rotate through the first motor, so that the screw rod is driven to move forwards, the fixed block connected with the screw rod moves forwards under the action of a driving force and extrudes the spring connected with the lock pin, the lock pin generates a trend of moving forwards under the action of the spring force, at the moment, the locking key is pressed down, the tension of the spring extruded on the lock pin clamped with the locking key is released, the lock pin is clamped with the adjustable clamping component under the action of the thrust of the spring, and therefore locking of the seal lock is achieved; it should be noted that, in the movement process of the lock pin driven by the spring, the unlocking push block connected with the lock pin is pushed by the lock pin to leave the second travel switch (under the condition of unlocking, the unlocking push block is close to the second travel switch to close the second travel switch), the first circuit board connected with the second travel switch receives the signal of disconnecting the second travel switch, and meanwhile, the disconnecting signal when the screw rod in the driving assembly leaves the third travel switch is also transmitted to the first circuit board, so as to judge that the seal lock at this time is in the locking state; of course, the above description only illustrates that the article to be stamped has a small volume, and similarly, when the article to be stamped has a large volume, the position of the adjustable engaging member is adjusted, and then the article to be stamped is locked to clamp the article with a large volume.

It should be noted that the present invention provides two embodiments of the adjustable engaging member; the first method comprises the following steps: a plurality of clamping teeth are arranged on a binding belt, and a locking pin is clamped with the clamping teeth at different positions on the binding belt by adjusting the position of the binding belt, so that objects to be sealed with different volumes are clamped; the second method comprises the following steps: the steel rope, the ratchet wheel and the driven wheel are clamped with the lock pin through the clamping teeth on the inner edge of the ratchet wheel, the clamping space on the bearing part is adjusted through the steel rope on the outer edge of the ratchet wheel, the steel rope is guided and moves in an auxiliary mode through the outer edge of the ratchet wheel and the driven wheel, and meanwhile, the clamping of the two wheels also plays a role in preventing the steel rope from retracting; in addition, when the lock is in an unlocking state, the first motor drives the first gear set to rotate to drive the screw rod to move backwards, meanwhile, the fixed block also moves backwards, the spring is not extruded by the fixed block any more, the tension of one end connected with the fixed block is released, and the lock pin is pulled to move backwards to be separated from the adjustable clamping component, so that the seal lock can be automatically locked and unlocked without an external unlocking device; of course, the lock can be unlocked by using the lock opener, and whether the lock opener is arranged or not can be determined according to actual use.

On the other hand, a second motor in the unlocking device drives the second gear set to rotate, so that the unlocking push rod is driven to move forwards. The front end part of the unlocking push rod penetrates through the emergency unlocking hole to push the unlocking push block, and then the locking assembly in contact with the unlocking push block is separated from the adjustable clamping component, so that unlocking is automatically realized; furthermore, an unlocking hole is formed in the lock opener shell, an emergency push rod is arranged at the front end of the unlocking push rod, and the emergency push rod is exposed out of the unlocking hole; when the situation that the unlocking push rod cannot be driven to move by the second motor or automatic unlocking cannot be achieved due to the fact that the lock opener is exhausted of electric quantity occurs, the seal lock can be unlocked in a mode that the emergency push rod is pushed manually, specifically, the emergency push rod pushes the front end portion of the unlocking push rod to move, the unlocking push block is pushed through the front end portion of the unlocking push rod, the unlocking push block pushes the lock pin to be separated from the adjustable clamping component, and therefore unlocking is achieved.

In another aspect, thanks to the first circuit board connected to the second travel switch and the third travel switch, the unlocking state information and the unlocking times of the current seal lock are acquired, and the unlocking state information and the unlocking times are stored in the first communication module or the storage module connected to the communication module. And a second communication module connected with the first communication module in the lock opener shell acquires unlocking state information and unlocking times from the storage module and directly sends the unlocking state information and the unlocking times to a background server or forwards the unlocking state information and the unlocking times to the background server through a mobile terminal.

The unlocking code information comprises: the system comprises a lock number, an unlocking state code (an unlocking code corresponding to the unlocking state and an locking code corresponding to the locking state), an address code and a secondary code, wherein each seal lock is provided with a fixed lock number which is a unique identification number set when the seal lock leaves a factory, the state code changes along with whether the seal lock is in the unlocking state or the locking state, namely whether the second travel switch is closed (the second travel switch is closed and the second travel switch is opened and closed to obtain whether the current state of the seal lock is the locking state or the unlocking state, if the current state of the seal lock is the locking state, the state code corresponds to the locking state code, and if the current state of the seal lock is the unlocking state, the state code corresponds to the unlocking state code. The address code is a physical address of the seal lock, the secondary number is the unlocking times of the seal lock, and the secondary number is recorded as the unlocking times according to the closing times of the second travel switch and the unlocking push block, so that the secondary number is obtained.

The seal lock manager is connected with the first communication module or the Bluetooth module on the first circuit board and is further used for receiving unlocking code information sent by the Bluetooth module or the communication module arranged on the first circuit board and sending the unlocking code information to the background server.

And the background server checks the secondary number received from the seal lock manager with the secondary number sent by the second communication module of the lock opener, judges whether the seal lock is opened or not, and prompts abnormal unlocking if the secondary number is different from the secondary number.

Referring to fig. 9, in an embodiment, the control system includes: the system comprises a seal lock 10, a lock opener 20 for opening the seal lock 10, a seal lock manager 50 for acquiring an unlocking state code of the seal lock and sending the unlocking state code to a background server 40, and a mobile terminal 30 for receiving a lock code, an unlocking state code or a locking state code, and a time code sent by the lock opener and sending the lock code, the unlocking state code or the locking state code, and the time code to the background server 40. The mobile terminal 30 and the background server 40 may both be configured to check the status information of the seal lock, and obtain the current unlocking status or locking status of the seal lock, and the unlocking times and other information.

Example two:

the invention also discloses a seal lock control method based on the control system, which comprises the following steps:

when the facing slip lock is in an unlocked state, adjusting the position of an adjustable clamping component in the facing slip lock, pushing a fixed block compression spring by adopting a driving assembly, pressing a locking button, clamping a lock pin with the adjustable clamping component, and locking the facing slip lock;

When the situation that the screw cannot be driven to move by the driving assembly or the lock cannot be automatically unlocked due to the fact that the electric quantity in the lock opener is exhausted occurs, the unlocking push block can be pushed through the emergency unlocking hole, and then the unlocking push block pushes the lock pin to be separated from the adjustable clamping component, so that unlocking is achieved.

It should be noted that the seal lock of the present invention can be locked or unlocked by the power supplied by the power unit, and it should be understood that the seal lock of the present invention can be manually locked by the locking button (the spring force is pre-tightened when not locked, and is released after the locking button is pressed, so that the lock pin is engaged with the adjustable engaging member to lock) in the case where the seal lock does not include the power unit, and the lock is unlocked by the lock opener of the present invention or the lock is unlocked by the manual unlocking means, so that the seal lock without the power unit is also within the scope of the present invention as claimed.

In summary, the adjustable engaging member is disposed in the seal lock housing, and the engaging position between the adjustable engaging member and the locking assembly is adjusted, so that objects with different volumes on the bearing member can be clamped. Electronic seal lock in this embodiment can not only manually unblank, can also realize unblanking through the power component who sets up in the seal lock body, can also unblank through the lock opener outside the lock body, furthermore, can also appear under the unusual circumstances that can not unblank of state at power component and/or lock opener, realize manual urgent unblanking through the urgent unlocking hole that sets up on the lock shell, benefit from second travel switch and the third travel switch of being connected with first circuit board simultaneously, all can accurate record state information of unblanking and the number of times of unblanking under the circumstances of automatic or manual unblanking.
