The working principle of the control system of the present embodiment is as follows:
in one aspect, an object to be sealed (such as a bag) is first placed in a lock housing, and the object to be sealed is clamped in or taken out from the lock body through closing and opening of an upper cover and a lower cover of the lock housing. In addition, a seal opening can be arranged on the lock shell body, the object to be sealed is placed in the seal opening, and the seal opening is clamped with the upper cover and the lower cover of the lock shell body, so that the object to be sealed is clamped in the seal opening.
When the lock is needed to be locked, the pushing block in the first unlocking hole is pushed to enable the locking push rod to be clamped with the clamping component, so that the seal lock seals the object to be sealed, the sliding switch detects the position change of the lock tongue at the moment, the state of the seal lock is changed from the unlocking state to the locking state, the control chip on the circuit board updates the detected unlocking state information and the unlocking times stored in the memory, and the unlocking state information and the updated unlocking times are stored in the communication module.
When a third communication module on a second circuit board in the unlocking device shell receives an unlocking instruction sent by a background server, the unlocking instruction is sent to a second control chip, the second control chip controls a motor driving gear set to drive a screw to move, and the screw pushes the locking assembly to be separated from the clamping component, so that unlocking is finally achieved.

And a second communication module connected with the first communication module in the unlocking device shell acquires unlocking state information and unlocking times from the storage module and directly transmits the unlocking state information and unlocking times to a background server or forwards the unlocking state information and unlocking times to the background server through the mobile terminal.
The unlocking code information comprises: the lock number, the unlocking state code (unlocking code corresponding to the unlocking state and unlocking code corresponding to the unlocking state), the address code and the secondary code, wherein each seal lock is provided with a fixed lock number which is a unique identification number set by the clip seal lock when leaving a factory, the state code changes along with whether the clip seal lock is in the unlocking state or the unlocking state, the state code is the sliding switch, the state of the current clip seal lock is obtained according to the judged position of the lock tongue and is the unlocking state or the unlocking state, if the current clip seal lock is in the unlocking state, the state code is corresponding to the unlocking state code, and if the current clip seal lock is in the unlocking state, the state code is corresponding to the unlocking state code. The address code is the physical address of the seal lock, the secondary number is the unlocking times of the clip type seal lock, the separation times of the lock tongue and the clamping part identified by the sliding switch are recorded as the unlocking times, and therefore the secondary number is obtained.
The seal lock manager which is connected with the first communication module or the Bluetooth module on the first circuit board is also 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 a background server.
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 unlocking device to judge whether the seal lock is opened or not, and if the secondary number is different, the background server prompts unlocking abnormality.
In a specific embodiment, as shown in connection with fig. 8, the control system comprises: the seal lock 10 is used for unlocking an unlocking device 20 of the seal lock 10, acquiring an unlocking state code of the seal lock, transmitting the unlocking state code to a seal lock manager 50 of the background server 40, receiving a lock code, an unlocking state code or a locking state code and a time code transmitted in the unlocking device, and transmitting the lock code, the unlocking state code or the locking state code and the time code to the mobile terminal 30 of the background server 40. Both the mobile terminal 30 and the background server 40 may be configured to view the status information of the seal lock, and obtain the current unlocking state or unlocking state, and the unlocking times thereof.
It is conceivable that, in the specific implementation, the unlocking procedure of the seal lock can be started by setting the unlocking key, the unlocking password does not need to be sent through the mobile terminal, the mobile terminal can also send the unlocking password through scanning the two-dimensional code on the lock shell, and the like, which are all conceivable embodiments based on the above.
Embodiment two:
