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 is worth mentioning that the adjustable engaging member of the present invention provides two embodiments; 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.
