Description

Technical Field

[0001] The present invention belongs to the technical field of cabinet emergency unlocking safety, and in particular relates to an emergency unlocking key and method based on double authentication protection. Background Art

[0002] In the traditional concept of emergency keys and locks, one key opens one lock. However, with the rapid development of science and technology, smart locks have begun to emerge in an endless stream. It is a perfect combination of computer technology, electronic technology, mechanical technology and modern hardware technology.

[0003] Smart locks are composed of two parts: electronic identification control and mechanical linkage system. This type of smart lock integrates all structures, controls, and authentication into the lock itself, and the overall price is relatively expensive. In addition, traditional emergency keys are completely discarded, and it is impossible to open the corresponding equipment box door and leave a record of who opened the door when the smart lock itself fails and cannot be used. This leaves a greater risk of hidden dangers and failure to open the door in time when in use.

[0004] The electric lock system of the cabinet is composed of an electric lock, a lock control circuit, and a mechanical lock emergency linkage device. When the electric lock installed on the cabinet door cannot be opened by electric control, the mechanical lock emergency linkage device installed on the cabinet door can be used to open the cabinet door. When the mechanical lock emergency linkage device is used to open the cabinet door, it is impossible to record who opened the cabinet door. When the items in the cabinet are wrong, it is impossible to track the whereabouts of the items, which leaves a greater hidden danger in the safety of the items and causes disputes. In addition, the mechanical lock key is also very easy to copy. Summary of the invention

[0005] In order to overcome the deficiencies of the prior art, the present invention provides an emergency unlocking key and method based on double authentication protection.

[0006] An emergency unlocking key based on double authentication protection comprises: a double authentication emergency unlocking key and an electric control lock for a cabinet; a control chip, a battery control circuit and a built-in rechargeable battery pack are arranged in a key shell of the double authentication emergency unlocking key, the control chip comprises a double authentication module, a processor and a storage module, the double authentication module and the storage module are respectively connected to the processor, the control chip is respectively connected to the battery control circuit and the communication port, the built-in rechargeable battery pack is connected to the battery control circuit and the charging port, the battery control circuit is respectively connected to a power switch and an output socket interface A, and the battery control circuit is connected to the control chip and the built-in rechargeable battery pack; the surface of the key shell is provided with: an authentication I indicator light, an authentication II indicator light, an equipment operation indicator light and an authentication card reading area mark; the double authentication emergency unlocking key is connected to a first output socket interface, one end of an output socket connection cable is connected to a first output socket connector, and the other end of the output socket connection cable is connected to a second output socket connector; the first output socket interface is connected to the first output socket connector, and the second output socket interface is connected to the second output socket connector.

[0007] The output socket connector A of the double-authentication emergency unlocking key is connected to the output socket connector B of the double-authentication emergency unlocking key, and the other end of the output socket connector B is respectively connected to the electric control lock.

[0008] An emergency key unlocking method based on double authentication protection includes the following steps: recording the card number information and time of the authentication personnel; controlling the on and off of the battery pack, encrypting the line sequence combination of the output socket output interface end, and authenticating, controlling, modifying and managing the key through the communication port.

[0009] Also contains the following steps;

[0010] Step 1: Control the control chip through the communication port to store the legal card number into the storage module to form a legal card number set.

[0011] Step 2: The manager performs a card authentication comparison, comparing card authentication I with the legal card number set. If the comparison is successful, card authentication II is then compared with the legal card number set. If the comparison is successful, that is, both card authentication I and card authentication II are successfully compared, the dual authentication mechanism determines that the authentication is successful and records the card number and time.

[0012] Step 3: After the authentication is successful, the system records the card number and time of the authenticated person, and connects the rechargeable battery pack to the output socket combination interface by controlling the battery control circuit, and the emergency unlocking key is in normal working state;

[0013] Step 4. Plug one end of the output socket cable into the output socket interface of the unlocking key, and the other end into the output socket interface reserved for the cabinet electric lock. At this time, the unlocking key is connected to the cabinet electric lock, and the cabinet door opens; the output socket interface A of the dual-authentication emergency unlocking key is connected to the output socket interface B reserved for the cabinet electric lock, directly controlling the unlocking coil of the cabinet electric lock, which has nothing to do with the original control circuit of the cabinet electric lock.

[0014] Step 5: Encrypt the line sequence of the output socket output end, use 8-core cable, and you can combine Combination methods: two lines can be swapped and combined In this way, the line sequence of the output end of the output socket supports 56 combinations at the same time, making keys with different codes.

[0015] Step 6, the emergency key controls the authentication time. When the set time is exceeded, the battery control circuit of the emergency unlocking key disconnects the built-in rechargeable battery pack from the output socket interface, and the emergency unlocking key is in a non-working state, achieving the purpose of one key opening one lock within the set time.

[0016] Step 2 also contains the following steps:

[0017] The rechargeable battery of the key connection process is connected to the charging interface and the battery control circuit, the battery control circuit is connected to the output socket output port, and the output socket output port is connected to the unlocking. The double authentication process is that when the electric lock cannot be opened normally and emergency unlocking operation is required, two managers are required to read the card for authentication in succession. The authentication information is checked in the legal card number set group. When any authentication fails, re-authentication must be performed; when two authentication personnel successfully match the legal card number set group at the same time, the matched card number and time are recorded; at the same time, during the key connection process, the rechargeable battery pack is connected to the output socket output port through the battery control circuit. At this time, the double authentication emergency unlocking key is in working condition and the unlocking operation is performed.

[0018] The beneficial effects of the present invention are as follows: the emergency key can control the authentication time. When the set time is exceeded, the battery control circuit of the emergency unlocking key disconnects the connection between the built-in rechargeable battery pack and the output socket interface, and the emergency unlocking key is in a non-working state, thereby achieving the purpose of one key opening one lock within the set time.
