When it is determined that the identification code is not stored in the lock 10, the identification code is stored.

When it is determined that the identification code has been stored in the lock 10, the identification code is deleted from the storage of the lock 10, and it is determined whether the number of identification codes currently stored in the lock 10 is 0.

When it is determined that the number of the identification codes currently stored in the lock 10 is 0, unlocking is performed.

The lock 10 detects that the computer key 20 is inserted, obtains the identity code, and determines whether the identity code is stored, which may be specifically implemented by the information processing component 200 disposed on the lock body 100 of the lock 10. Illustratively, the computer key 20 sends an electrical signal to the signal converter 210 of the lock 10, and the signal converter 210 receives the electrical signal and drives the control circuit 220 of the lock 10 to operate. Meanwhile, the signal converter 210 sends the identification code of the computer key 20 to the control circuit 220, and the control circuit 220 receives the identification code and determines whether the identification code is stored. The identification code of the computer key 20 may include at least one of identification information of a user of the computer key, an ID number of the computer key, a model number of the computer key, and the like. The computer key 20 sends the electrical signal to the signal converter 210 by mechanical contact transmission, for example, the contacts on the computer key contact the contacts of the signal converter. Alternatively, the computer key 20 may send the electrical signal to the signal converter 210, or may send the electrical signal in a contactless manner, for example, by using rfid technology.

When the control circuit 220 determines that the identity code has been stored, the identity code is deleted, and it is determined whether the number of currently stored identity codes is 0. It can be understood that the number of the identity codes currently stored at this time refers to the number of the remaining identity codes after the identity code is deleted. When the control circuit 220 determines that the number of the currently stored identity codes is 0, the lock opening and closing assembly 500 can be controlled to unlock the lock 10, so that the last operator can take the lock 10 conveniently, and the phenomenon of missing lock disassembly is avoided.

Further, after the step of determining whether the number of the identification codes currently stored in the lock 10 is 0, the method further includes the following steps: and when the number of the identity codes currently stored in the lock 10 is judged to be not 0, outputting the number of the identity codes currently stored in the lock 10. In this embodiment, when the control circuit 220 determines that the number of the stored identity codes is not 0, the control circuit 220 may control the output element 300 to output the number of the currently stored identity codes. It can be understood that the number of currently stored identity codes output at this time refers to the number of remaining identity codes after the identity code is deleted. In this way, the operator can be facilitated to know the number of work groups currently in order to determine whether the work on site is complete.

In one embodiment, after the step of deleting the identification code from the storage of the lock 10, the following steps are included: the number of identity codes currently stored in the lock 10 is output. In this embodiment, when the control circuit 220 determines that the identity code is stored, the identity code is deleted. Meanwhile, the control circuit 220 can control the output component 300 to output the number of the currently stored identity codes. It can be understood that the number of currently stored identity codes output at this time refers to the number of remaining identity codes after the identity code is deleted. In this way, the operator can be facilitated to know the number of work groups currently in order to determine whether the work on site is complete. When the number of the remaining identification codes after the identification code is deleted is 0, the output module 300 may output the identification code with the number of 0 to prompt the operator to take away the lock 10. When the number of the remaining id codes after the id codes are deleted is not 0, the output component 300 outputs the number of the id codes, so that the operator can know the number of the current work team.

Further, when the control circuit 220 determines that the identity code is not stored, the identity code is stored. Meanwhile, the control circuit 220 may control the output component 300 to output the number of currently stored identity codes. It can be understood that the number of currently stored identity codes output at this time refers to the number of identity codes after the identity code is added. In this way, the operator can know the number of the current work shift group.

In one embodiment, after the step of detecting the insertion of the computer key 20 into the lock 10, the method further comprises the following steps: the number of identity codes currently stored in the lock 10 is output. In this embodiment, when the computer key 20 is inserted, the computer key 20 sends an electrical signal to the signal converter 210, and the signal converter 210 receives the electrical signal and drives the control circuit 220 to operate. At this time, the control circuit 220 can directly control the output device 300 to output the number of the currently stored identity codes, so that the operator can know the number of the currently working team. When the control circuit 220 determines whether the identity code is stored later, the control circuit 220 deletes the identity code when determining that the identity code is stored, and at this time, the control circuit 220 controls the output component 300 to output the number of the remaining identity codes after the identity code is deleted. Or when it is determined that the identification code is not stored, the control circuit 220 stores the identification code, and then controls the output module 300 to output the number of the identification codes added with the identification code. Thus, the number of work teams and the change thereof can be conveniently known by the operator on the spot.

In one embodiment, the manner of outputting the number of identity codes currently stored in the lock 10 includes:

and indicating the number of the identity codes by using the indicator light modules in a one-to-one correspondence manner. Or the number of the identity codes is displayed by using the display screen module. Or the number of the identity codes is displayed by utilizing the rolling digital display module. Or the number of the identity codes is broadcasted by utilizing the voice module.

Accordingly, the output component 300 may be an indicator light 310. Alternatively, the output component 300 may also be the display screen 320. The output component 300 may also be other structures such as voice output or rolling digital display, as long as the operator can know the number of the identification codes.

In one embodiment, after the step of unlocking when it is determined that the number of the identification codes currently stored in the lock is 0, the method further includes: and judging whether the current lockset is successfully unlocked or not, and unlocking when judging that the current lockset is not successfully unlocked. Illustratively, whether the lock 10 is successfully unlocked is detected by the detection component 600, and the detection information is sent to the information processing component 200, specifically to the control circuit 220. If the lock 10 is determined not to be unlocked successfully, the control circuit 220 controls the lock assembly 500 to unlock the lock 10.

Further, after the step of determining whether the current lock is successfully unlocked, the method further includes: and when the current lockset is judged to be unlocked successfully, outputting the prompt message that the lockset 10 is not unlocked successfully. Illustratively, a warning message indicating that the lock 10 is not successfully unlocked can be output through the warning assembly 700, so as to remind the operator, thereby facilitating the operator to find a problem. The unlocking step can be performed by sending an unlocking instruction to the lock opening and closing assembly 500 of the lock 10 through the control circuit 220, and the lock opening and closing assembly 500 receives the unlocking instruction and performs the unlocking step, so that the lock 10 is unlocked.

Referring to fig. 9, taking the output assembly 300 as an indicator light 310 as an example, the lock and the working process thereof according to the embodiment of the present invention are specifically described:

at the start of the operation, the lock 10 is latched to the device to be latched. When the computer key 20 is inserted into the groove 231 on the outer side of the housing 230, the computer key 20 sends an electrical signal into the housing 230. The signal is converted by the signal converter 210 to generate a power signal for driving the control circuit 220. At the same time, the signal converter 210 sends the identification code of the computer key 20 to the mcu. After the micro control unit recognizes, if the identity code of the computer key 20 is not stored in the micro control unit, one of the indicator lamps 310 is turned on, and the identity code of the computer key 20 is stored. The number of lights 310 that are illuminated is equal to the number of computer keys 20 that are determined to not be stored in the lock 10. After the indicator lamp 310 is turned on, the computer key 20 is pulled out, and the indicator lamp 310 is turned off.

When other work teams need to work on site, the operator directly inserts the computer key 20 carried by the operator into the groove 231, and the computer key 20 sends an electric signal into the housing 230. The signal is converted by the signal converter 210 to generate a power signal for driving the control circuit 220. The mcu lights the already-operating indicator lamp 310 and the signal converter 210 sends the identification code of the computer key 20 to the mcu. The mcu determines that the id code of the computer key 20 is not stored in the mcu, and then adds an indicator light 310 to light up on the basis of the lit indicator light 310.

At the end of the work, the computer key 20 is inserted into the groove 231 on the outer side of the housing 230, and the computer key 20 sends an electric signal into the housing 230. The signal is converted by the signal converter 210 to generate a power signal for driving the control circuit 220. The mcu lights the already-operating indicator lamp 310 and the signal converter 210 sends the identification code of the computer key 20 to the mcu. If the mcu determines that the id code of the computer key 20 is stored, the mcu determines that the task is finished and turns off one of the indicator lights 310. The number of the indicator lamps 310 turned off is equal to the number of the identification codes of the computer key 20 at the end of the identified task. When the last indicator lamp 310 is turned off, the micro control unit drives the locking and unlocking assembly 500 to unlock the locking hook 400, and the lock 10 is opened. Finally the operator removes the lock 10 and the device allows operation.

Referring to fig. 10, taking the output module 300 as an example of the display screen 320, the lock 10 and the working process thereof according to the embodiment of the present invention are specifically described:

at the start of the operation, the lock 10 is latched to the device to be latched. When the computer key 20 is inserted into the groove 231 on the outer side of the housing 230, the computer key 20 sends an electrical signal into the housing 230. The signal is converted by the signal converter 210 to generate a power signal for driving the control circuit 220. At the same time, the signal converter 210 sends the identification code of the computer key 20 to the mcu. After the micro control unit recognizes, if it is determined that the identification code of the computer key 20 is not stored in the micro control unit, the display screen 320 displays "1", identifies the first work team, and stores the identification code of the computer key 20. When the computer key 20 is pulled out, the display screen 320 is turned off after power failure.

When other work teams need to work on site, the operator directly inserts the computer key 20 carried by the operator into the groove 231, and the computer key 20 sends an electric signal into the housing 230. The signal is converted by the signal converter 210 to generate a power signal for driving the control circuit 220. The display screen 320 displays the number of shift groups that have been in operation. At the same time, the signal converter 210 sends the identification code of the computer key 20 to the mcu. The mcu determines that the id code of the computer key 20 is not stored in the mcu, and controls the display screen 320 to increase a value based on the number of the work groups, i.e. the display screen displays "2".

At the end of the work, the computer key 20 is inserted into the groove 231 on the outer side of the housing 230, and the computer key 20 sends an electric signal into the housing 230. The signal is converted by the signal converter 210 to generate a power signal for driving the control circuit 220. The display screen 320 displays the number of shift groups that have been in operation. At the same time, the signal converter 210 sends the identification code of the computer key 20 to the mcu. The mcu determines that the id code of the computer key 20 is stored, and then the mcu determines that the task is finished, and controls the display screen 320 to decrease by one value based on the number of the work teams. When the value is reduced to 0, the micro control unit drives the lock opening and closing assembly 500 to unlock the lock hook 400, and the lock 10 is opened. Finally the operator removes the lock 10 and the device allows operation.
