[0046] like Figure 1As shown in the embodiment of this utility model, the automatic identification circuit 100 includes: a control module 110, a door lock module 120, an identification module 130, and an image module 140.

[0047] The control module 110 is connected to the device 200 to be serviced. The door lock module 120 includes at least one switch 121, with both ends of each switch 121 connected to a corresponding terminal A1, which is connected to the control module 110. The identification module 130 is connected to the control module 110 and is configured to identify maintenance personnel and generate corresponding authorization information. The control module 110 is configured to control the switches 121 to open or close based on the authorization information.

[0048] The image module 140 is connected to the control module 110. The image module 140 can acquire images of the equipment area SC to be maintained. The control module 110 is configured to control the equipment 200 to be maintained to stop when an unauthorized person is detected entering the equipment area SC, based on the image generated by the image module 140.

[0049] In this embodiment of the utility model, the facial information of maintenance personnel is pre-stored in an external management platform. The management personnel can issue work permissions to the corresponding maintenance personnel through the management platform and send the information of personnel with work permissions to the control module 110.

[0050] When a maintenance worker arrives at the area where the equipment 200 to be maintained is located, the recognition module 130 can recognize the facial image of the maintenance worker to determine whether the maintenance worker has the right to work. If the maintenance worker has the right to work, the switch 121 of the door lock module 120 is opened. If the maintenance worker does not have the right to work, the switch 121 of the door lock module 120 is closed or kept closed.

[0051] Furthermore, if an unauthorized external person enters the equipment area SC to be repaired, the image module 140 can acquire the person's facial image. The control module 110 identifies whether the person entering the equipment area SC to be repaired has the right to work based on the image generated by the image module 140. If it is determined that the person is an unauthorized person, the control module 110 controls the equipment 200 to be repaired to stop to avoid accidental contact and potential danger.

[0052] In this embodiment of the invention, the identification module 130 of the automatic identification circuit 100 can automatically identify maintenance personnel, and the control module 110 opens or closes the switch 121 of the door lock module 120 according to the generated authorization information, thereby achieving automatic locking or unlocking. Simultaneously, the control module 110 can also, based on the image of the equipment under maintenance area SC acquired by the image module 140, control the equipment under maintenance 200 to stop when unauthorized personnel intrude into the equipment under maintenance area SC, in order to avoid safety hazards and achieve real-time monitoring.

[0053] like Figure 2 As shown, in some embodiments, the automatic identification circuit 100 further includes a safety module 150, which is connected to the control module 110.

[0054] When switch 121 is closed, the safety module 150 generates a lock confirmation signal and sends the lock confirmation signal to the control module 110. When switch 121 is open, the safety module 150 generates an unlock signal and sends the unlock signal to the control module 110.

[0055] When the control module 110 receives an unlocked signal, or when the control module 110 does not receive a confirmation lock signal or an unlocked signal corresponding to the switch 121, the control module 110 controls the equipment 200 to be maintained to stop.

[0056] In this embodiment, the safety module 150 detects whether the switch 121 of the door lock module 120 is properly closed or open. When the control module 110 receives an unlocked signal, it controls the device 200 to be repaired to stop, thus forming the first safety for the door lock circuit.

[0057] If the safety module 150 malfunctions, causing the control module 110 to not receive the unlocked signal or the unlocked signal generated by the safety module 150, the device 200 under maintenance will be shut down, forming a second safety for the door lock circuit.

[0058] By cooperating with the security module 150 and the control module 110, the status of the switch 121 in the door lock module 120 is confirmed a second time, thereby improving the safety and reliability of the equipment.

[0059] In some embodiments, the automatic identification circuit 100 further includes an indicator module 160, which is connected to the control module 110. The indicator module 160 is configured to emit a corresponding indicator light when the control module 110 controls the equipment 200 to be repaired to stop.

[0060] In this embodiment, while the control module 110 controls the equipment 200 to be repaired to stop, the control indicator module 160 emits an indicator light to remind maintenance personnel or managers to confirm whether unauthorized personnel have entered the area SC of the equipment to be repaired, or whether the switch 121 of the door lock module 120 has not been properly opened or closed, so as to deal with safety hazards in a timely manner.

[0061] In some embodiments, the automatic identification circuit 100 further includes a warning module 170, which is connected to the control module 110. The warning module 170 is configured to generate a warning message and send the warning message to an external device when the control module 110 controls the equipment 200 to be repaired to stop.

[0062] In this embodiment, the warning module 170 can send warning information to external devices (such as mobile phones of maintenance personnel or managers, electronic devices with management platforms installed, etc.), so that the external devices issue warnings and promptly remind maintenance personnel or managers that the switch 121 of the door lock module 120 is not properly opened or closed, or that unauthorized personnel have entered the area SC of the equipment to be repaired.

[0063] like Figure 3 As shown, in some embodiments, the control module 110 includes a safety detection unit 111 and a control unit 112, wherein the safety detection unit 111 is connected to the control unit 112, and the control unit 112 is connected to the device 200 to be repaired.

[0064] The door lock module 120 includes two switches 121, each switch 121 includes two terminals A1, and one terminal A1 of each switch 121 is connected to the control unit 112, and the other terminal A1 is connected to the security detection unit 111 and the control unit 112.

[0065] The safety detection unit 111 is configured to detect the switch 121 circuit status of the two switches 121, generate corresponding detection results, and send the detection results to the control unit 112. The detection results include the normal state of the switch 121 circuit and the abnormal state of the switch 121 circuit.

[0066] In the event of an abnormal circuit condition of switch 121, control unit 112 controls the equipment 200 to be maintained to stop.

[0067] like Figure 4 and Figure 5As shown, in this embodiment, the door lock module 120 includes two switches 121, namely a first switch 1211 and a second switch 1212. The first switch 1211 includes a first terminal A11 and a second terminal A12, and the second switch 1212 includes a third terminal A13 and a fourth terminal A14. The first terminal A11 is connected to the security detection unit 111 and the control unit 112, the second terminal A12 is connected to the control unit 112, the third terminal A13 is connected to the security detection unit 111 and the control unit 112, and the fourth terminal A14 is connected to the control unit 112.

[0068] When the door lock is open, the first switch 1211 and the second switch 1212 are open; when the door lock is locked, the first switch 1211 and the second switch 1212 are closed. After both the first switch 1211 and the second switch 1212 are opened or closed, the safety detection unit 111 detects the switch 121 circuit status. If the first switch 1211 and the second switch 1212 are normally open or normally closed, the detection result is that the switch 121 circuit is in a normal state; if the first switch 1211 and the second switch 1212 are not normally open or normally closed, the detection result is that the switch 121 circuit is in an abnormal state.

[0069] While the safety detection unit 111 detects whether the switch 121 circuit status of the two switches 121 of the door lock module 120 is normal, the control unit 112 can also detect whether the switch 121 circuit status of the two switches 121 of the door lock module 120 is normal and generate detection results through the first terminal A11 of the first switch 1211 connected to it. The detection results include the normal state of the switch 121 circuit and the abnormal state of the switch 121 circuit. When the detection result is that the switch 121 circuit is abnormal, the device 200 to be maintained is controlled to stop.

[0070] The safety detection unit 111 and the control unit 112 detect the status of the switch 121 circuit respectively, thereby realizing secondary confirmation of the status of the switch 121 of the door lock module 120 and improving the reliability of the switch 121 circuit of the door lock module 120.

[0071] like Figure 6 As shown, this utility model also proposes an automatic identification door lock 300, which includes an automatic identification circuit 100, a door lock body 310, and a visual warning device 320 as described in any of the foregoing embodiments. The automatic identification circuit 100 includes a control module 110, a door lock module 120, an identification module 130, and an image module 140.

[0072] The control module 110 is connected to the device 200 to be serviced. The door lock module 120 includes at least one switch 121, with both ends of the switch 121 connected to terminal A1, which in turn is connected to the control module 110. The identification module 130 is connected to the control module 110 and is configured to identify maintenance personnel and generate corresponding authorization information. The control module 110 is configured to control the switch 121 to open or close based on the authorization information.

[0073] The image module 140 is connected to the control module 110. The image module 140 can acquire images of the equipment area SC to be maintained. The control module 110 is configured to control the equipment 200 to be maintained to stop when an unauthorized person is detected entering the equipment area SC, based on the image generated by the image module 140.

[0074] The door lock module 120 is located inside the door lock body 310, and the image module 140 is located inside the visual warning device 320, enabling the visual warning device 320 to acquire images of the area SC of the equipment to be repaired. The automatic recognition circuit 100 is configured to control the equipment 200 to be repaired to stop when it detects that an unauthorized person has entered the area SC of the equipment to be repaired, based on the images acquired by the visual warning device 320.

[0075] In this embodiment, the facial information of maintenance personnel is pre-stored in an external management platform. The management personnel can issue work permissions to the corresponding maintenance personnel through the management platform and send the information of personnel with work permissions to the control module 110.

[0076] When a maintenance worker arrives at the area where the equipment 200 to be maintained is located, the recognition module 130 can recognize the facial image of the maintenance worker to determine whether the maintenance worker has the right to work. If the maintenance worker has the right to work, the switch 121 in the door lock body 310 is opened. If the maintenance worker does not have the right to work, the switch 121 in the door lock body 310 is closed or the switch 121 in the door lock body 310 is closed and kept closed.

[0077] Furthermore, if an unauthorized person enters the equipment area SC to be repaired, the visual warning device 320 can acquire the person's facial image. The control module 110 identifies whether the person entering the equipment area SC to be repaired has the right to work based on the image generated by the visual warning device 320. If it is determined that the person is an unauthorized person, the control module 110 will stop the equipment 200 to be repaired to prevent accidental contact and potential danger.

[0078] The automatic identification door lock 300 of this utility model includes an automatic identification circuit 100, which can automatically identify maintenance personnel.
