[0002] As an indispensable part of building equipment, the safe use of elevators has received more and more attention from all walks of life. The existing emergency unlocking device uses a triangular key to turn the lock cylinder to drive a lever behind the elevator floor door, and then drives the elevator floor door lock device to enter the shaft through the lever to achieve emergency rescue or related maintenance of the elevator. There are some shortcomings in the use of the existing emergency unlocking device in the elevator. First, because the unlocking keys are widely universal, in daily use, anyone with the key can open the elevator floor door, and the accident of opening the floor door by mistake will cause falling into the shaft; second, there will be a situation where the door panel machine or other components installed on the top of the car are stolen, which is caused by the universality of the floor door emergency unlocking device. Secondly, in terms of elevator maintenance, generally two designated maintenance personnel maintain the elevators of one or more units or communities. The universal emergency unlocking device cannot understand whether the maintenance personnel perform regular and quantitative maintenance work on the elevator every month as required.

[0017] The specific implementation of the present application is described in detail below with reference to the accompanying drawings.

[0018] Embodiment: An intelligent emergency unlocking device that introduces biometric technology, such as Figure 1 As shown, it includes a power module 8, a main control module, a biometric technology module 2 and an electromagnetic lock 5. The power module 8 is used to power the intelligent emergency unlocking device. The biometric technology module 2 and the electromagnetic lock 5 are both connected to the main control module. The biometric technology module 2 is used to verify the identity of the unlocker.

[0019] The main control unit 1 adopts the STM32F103 chip of STMicroelectronics. In a specific embodiment scenario, a circuit board or a housing carrying the main control unit 1 is installed on the inner side of the elevator door.

[0020] The biometric identification module 2 is a fingerprint entry / recognition module 21, and the fingerprint entry / recognition module 21 is installed on the outside of the elevator door.

[0021] like Figure 2 As shown, the fingerprint entry / recognition module 21 includes a registration part 211 and a recognition part 212. The registration part 211 specifically includes fingerprint image acquisition, fingerprint image preprocessing, fingerprint feature extraction, and template feature database, and the recognition part 212 specifically includes fingerprint image acquisition, fingerprint image preprocessing, fingerprint feature extraction, fingerprint feature matching, and sends the fingerprint image matching result to the main control unit 1.

[0022] The electromagnetic lock 5 is installed on the elevator. The electromagnetic lock 5 has a locking rod. When the electromagnetic lock 5 is locked, the locking rod extends to block the lever in the triangular lock. When the electromagnetic lock 5 is opened, the locking rod retracts. The electromagnetic lock 5 is controlled by the main control module. The main control module controls the electromagnetic lock 5 in a mode that controls the electromagnetic lock 5 to be unlocked when the identity of the unlocker is verified by the biometric identification module 2, and controls the electromagnetic lock 5 to be locked when the identity of the unlocker is not verified by the biometric identification module 2.

[0023] Specifically, Figure 3As shown, the electromagnetic lock 5 is arranged on one side of the elevator triangular lock 7, and when the elevator triangular lock 7 and the electromagnetic lock 5 are both in a locked state, the locking rod is parallel to the lever in the elevator triangular lock 7, and the locking rod is located on the rotating side of the lever. Therefore, even if there is a triangular key, the triangular lock cannot be opened at this time.

[0024] The electromagnetic lock 5 can be a product with a controllable retractable lock rod. In this embodiment, the electromagnetic lock 5 adopts an existing product, whose model is LSD-1564B push-pull electromagnet.

[0025] The triangular lock comes with the elevator. This application does not change the original structure of the elevator. Its corresponding product is suitable for existing elevators and has good market value.

[0026] In another specific embodiment of the present application, an intelligent emergency unlocking device that introduces biometric technology also includes an elevator data acquisition module 3, which is installed on the inside of the elevator door to collect elevator operation signals and leveling signals collected by sensors in the elevator and transmit them to the main control module. The elevator data acquisition module 3 includes submodules such as a reference voltage source, a conversion and isolation circuit, a communication interface, a DC calibration circuit, a tracking / holding circuit (T / H), an A / D conversion, a microprocessor, and an acquisition card internal bus. The elevator data acquisition module 3 collects data from elevator sensors (existing in the elevator) through an acquisition card, and transmits it to the main control module after being aggregated and processed by the microprocessor. It also includes an indication status module 4, which is connected to the main control module and is used to display the elevator operation status, elevator floor, and electromagnetic lock 5 unlocking information.

[0027] In another specific embodiment of the present application, an intelligent emergency unlocking device that introduces biometric technology also includes a voice broadcast module 6, which is connected to the main control module. Specifically, after the fingerprint entry / recognition module 21 successfully verifies, a voice broadcast is issued to remind the staff.

[0028] In another specific embodiment of the present application, an intelligent emergency unlocking device that introduces biometric recognition technology also includes a background 9, which is connected to the main control module in communication, and the background 9 is any one of a cloud server, a remote terminal and a storage device. The fingerprint information recognized by the fingerprint entry / recognition module 21 can be transmitted to the background 9 for storage, management, statistics and the like.

[0029] The specific working process of the intelligent emergency unlocking device introduced with biometric recognition technology in this embodiment is as follows:

[0030] Step 1: The fingerprint information of the maintenance personnel is collected, entered, and features are extracted through the fingerprint entry / recognition module 21 and then stored in the template feature database;

[0031] The elevator data acquisition module 3 transmits the collected elevator signal information to the main control unit 1, and the main control unit 1 transmits it to the indication status module 4, and the indication status module 4 displays the elevator operation status, elevator floor, sensor fault information, electromagnetic lock 5 unlocking information, triangular lock opening status, etc.;

[0032] Step 2: When rescue or elevator maintenance is required, the fingerprint information of the designated person is first collected, entered, and features are extracted through the fingerprint entry / recognition module 21, and then the fingerprint is compared with the template feature database information. If the fingerprint image matches, the fingerprint image matching result data is sent to the main control unit 1, and the main control unit 1 controls the electromagnetic lock 5 to move. At the same time, the voice broadcast module 6 gives a voice prompt, and the locking rod of the electromagnetic lock 5 retracts. The locking rod of the electromagnetic lock 5 no longer blocks the triangular lock lever 71, and the elevator triangular lock 7 can continue to be opened with the triangular key. If the fingerprint information of the designated person does not match, the main control unit 1 will not control the electromagnetic lock 5 to move.

[0033] The above is only a preferred implementation of the present application. It should be pointed out that a person skilled in the art can make several modifications and improvements without departing from the inventive concept of the present application, and these all fall within the scope of protection of the present application.
