Detailed Description
The following detailed description of specific embodiments of the present disclosure is provided in connection with the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.
There are two main types of existing intelligent door locks.
Fig. 1 is a schematic view of a prior art door lock.
The door lock includes a lock cylinder, an exterior panel located on an exterior side of the door, and a handle. The external panel is provided with a main control singlechip, a driving module and an unlocking input module (one or more of a password key, a fingerprint identifier and a card reader). The master control single chip microcomputer is used for verifying whether the unlocking information received by the unlocking input module is the same as the preset unlocking information. For example, whether the password received by the password key is the same as the preset password, whether the fingerprint received by the fingerprint recognizer is the same as the preset fingerprint, and whether the information (such as the radio frequency signal sent by the radio frequency card) of the card received by the card reader is the same as the preset card information.
If the master control single chip microcomputer verifies whether the unlocking information received by the unlocking input module is the same as the preset unlocking information or not, the driving module is controlled to drive the clutch device in the handle positioned on the outer side of the door to be in contact with the lock cylinder penetrating through the whole door. The user can drive the lock core to rotate through clutch through rotating the handle, and then opens the lock.
All control and mechanical linkage of this lock scheme are all in the outside panel, and the security is lower, if directly destroy the outside panel, just can open the lock. In addition, the signal for controlling the clutch device is at a fixed high or low level, and is susceptible to interference of strong radiation (such as a tesla coil or an interphone) to open the door.
Fig. 2 is a schematic view of a door lock according to an embodiment of the present disclosure.
As shown in fig. 2, the door lock provided in this embodiment includes an inner panel 1 disposed inside the door body, an outer panel 2 disposed outside the door body, a lock body 3 disposed inside the door body, and a lock cylinder 4 disposed in the inner panel 1 and inserted into the lock body.
An unlocking module 5 and an unlocking input module 6 are provided in the exterior panel 2, which are connected to each other. The inner panel 1 is provided with a drive control module 7 and a drive module 8 which are connected with each other, and the drive module 8 is connected with the lock cylinder 4.
The unlocking input module 6 is used for acquiring unlocking information.
The unlocking module 5 is configured to determine whether the unlocking information matches the preset information, and send unlocking data to the drive control module 7 when it is determined that the unlocking information matches the preset information.
The drive control module 7 is used for determining whether the unlocking data is matched with the preset data or not in response to the received unlocking data, and controlling the drive module 8 to drive the lock cylinder 4 to unlock the lock body when the unlocking data is determined to be matched with the preset data.
Specifically, the inner panel 1 and the outer panel 2 may be of metal, plastic or resin.
The unlocking module 5 and the driving control module 7 in the present disclosure may be any chip with a control function, such as a single chip, a PLC, a Complex Programmable Logic Device (CPLD), a Field Programmable Gate Array (FPGA), and a Central Processing Unit (CPU).
The unlock input module 6 may be of various types.
In a further embodiment, based on the embodiment of fig. 2, the unlocking input module 6 comprises one or more of the following: the device comprises a first key, a chip sensing module, a face acquisition module, an iris acquisition module, a magnetic induction module and a fingerprint acquisition module.
Specifically, the first key may be a physical key or a virtual key on the touch screen. The content of the keys may be numbers from 0 to 9, and may include 26 letters, or even various icons.
The chip sensing module can read the content in the chip, such as a string of numbers, letters or characters.
The magnetic induction module can read the information of the magnetic stripe of the magnetic card.
Alternatively, the unlock input module 6 may be another module having an identity determination function. Such as an iris detection module, or a face recognition module.
The type of the unlock input module 6 corresponds to the type of the acquired unlock information. For example, the unlocking input module 6 is a fingerprint acquisition module, and the unlocking information is a fingerprint sample. The unlocking input module 6 is a first key, and the unlocking information is a password.
The door lock of the embodiment can receive various types of unlocking information by various types of modules, so that the door lock can be unlocked in various unlocking modes.
In another embodiment, based on the embodiment of fig. 2, the unlocking module 5 and the driving control module 7 may be connected through a cable communication, or may communicate through a bluetooth chip. For example, the unlocking module 5 includes a first bluetooth chip, the driving control module 7 includes a second bluetooth chip, and the first bluetooth chip and the second bluetooth chip are in communication connection.
In the above embodiment, two channels are provided for communication between the unlock module 5 and the drive control module 7.
The unlocking information and the preset information may include, but are not limited to, one or more of a password, fingerprint information, radio frequency signal, iris information.
In practical applications, a user may input preset information into the unlock input module 6. For example, the unlock input module 6 is a fingerprint acquisition module, and the fingerprint acquisition module enters a fingerprint of a user. The unlocking module 5 takes the input fingerprint as preset information.
For another example, the unlock input module 6 is a magnetic induction module, the user can record the number of the magnetic card into the magnetic induction module by swiping the magnetic card, and the unlock module 5 uses the recorded number of the magnetic card as the preset information. The unlocking module 5 may compare the number (unlocking information) of the magnetic card scanned by the magnetic induction module in real time with the preset information, and if the number (unlocking information) is the same as the preset information, it is determined that the unlocking information matches the preset information.
The condition that the unlocking information is matched with the preset information can be that the unlocking information is completely the same as the preset information, partially the same as the preset information, or the unlocking information and the preset information meet a certain condition. For example, when the unlocking information and the preset information are numbers and the sum of the unlocking information and the preset information is 100, the unlocking module 5 determines that the unlocking information and the preset information are matched. For another example, the unlocking information and the preset information are fingerprint information, and if the unlocking information and the preset information have the same characteristics exceeding a certain threshold number, it is determined that the unlocking information matches the preset information.
If the unlocking module 5 determines that the unlocking information matches the preset information, the unlocking module sends unlocking data to the drive control module 7, and if the unlocking module 5 determines that the unlocking information does not match the preset information, the unlocking module 5 may not send any data to the drive control module 7 or send unlocking failure data.
The unlock data, the preset data, and the unlock failure data may be high or low, or may be a small number.
The drive control module 7 determines whether the unlock data matches the preset data (the matching manner may be the same as the above-described manner in which the unlock information matches the preset information).
The preset data on the drive control module 7 may be the same as the unlock data for unlocking, or may match the unlock data (for example, when the sum of the unlock data and the preset data is 100, the drive control module 7 determines that the unlock data matches the preset data).
The unlocking module 5 in this embodiment can complete the function of verifying the unlocking information, and when the unlocking information is relatively complex (for example, fingerprint information), the unlocking module 5 needs to have an algorithm for identifying and comparing fingerprints, and at this time, the unlocking module 5 is a chip with relatively strong processing capability. The unlocking data processed by the drive control module 7 is much lower in data length and complexity than the unlocking information. Therefore, the drive control module 7 in this embodiment has low requirements on processing capability, and can use a cheap chip, thereby saving cost.
According to the technical scheme, the mechanical linkage part driving module, the lock cylinder and the lock body of the door lock are arranged in the external panel or the door body, so that the door lock is not easy to be cracked by violence from the outside of the door, and the safety is higher. Moreover, the acquisition and verification of the unlocking information are completed in the external panel in a centralized manner, and the internal panel is only provided with the driving control module, so that the simple unlocking data sent by the unlocking module outside the door can be processed, the structure is simple, and the cost is saved.
The process that the drive control module 7 receives the unlocking data sent by the unlocking module 5 may be interfered, so that the unlocking data is wrong, or the unlocking data is generated due to an interference signal when the unlocking data is not unlocked and the door lock is opened. The inventor reminds that the unlocking data are encrypted, the unlocking data are not easy to leak, and the safety of the door lock is higher.
In another embodiment, based on the embodiment of fig. 2, the unlocking module 5 comprises an encryption module for encrypting the unlocking data. And the unlocking module 5 is used for sending the encrypted unlocking data when the unlocking information is determined to be matched with the preset information. The drive control module 7 includes a decryption module for decrypting the encrypted unlock data. The driving control module 7 is used for controlling the driving module 8 to drive the lock cylinder 4 to unlock the lock body 3 under the condition that unlocking is successful.
Specifically, the Encryption method used for Encryption may be an Advanced Encryption Standard (AES), a Data Encryption Standard (DES), an asymmetric Encryption (RSA), or other Encryption methods.
In practical applications, the encryption may adopt some commonly used encryption methods, for example, a method of summing the unlocking data with the key, and the decryption may adopt a method of subtracting the encrypted unlocking data from the key. The key can be set manually, or a random number can be automatically generated by the unlocking module 5 or the driving control module 7 after the door lock is started for the first time, and the random number is used as the key.
The embodiment can encrypt the unlocked data, so that the door lock is not easy to be maliciously cracked, and the safety is higher.
