[0041] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, specific embodiments of the present invention are now described in detail with reference to the accompanying drawings.

[0042] First embodiment

[0043] refer to Figure 1 In this embodiment, the intelligent door lock control device based on LoRa communication includes a processor, a power supply module, a door lock control module, a card reading module, a first memory, and a LoRa communication module, and the processor is respectively connected to the power supply module, the door lock control module, the card reading module, the first memory, and the LoRa communication module. In the intelligent door lock control device, the processor is used to process data and control various modules of the system according to the program to keep the system working in coordination. The power supply module is used to power each module in the device. The door lock control module is connected to the door lock device to drive the door lock to open or close; the door lock control module can adopt a motor drive module, an electromagnet drive module, etc., and the motor drive module or the electromagnet drive module refers to the prior art. The card reader module is used to read the user account information of the access control card, and the user account information is pre-written in the access control card. The first memory is used to store the permission list, which is a list of all users who have the permission to open the door, that is, a list of legal users. After the card reader module reads the user account information of the access card, the user account information is matched with the permission list. When the user account information is matched, it means that the user is a legal user, and an unlocking command is sent to the door lock control module, and the door lock control module controls the door lock to open or close.

[0044] If the user account information is not in the permission list of the first memory, the LoRa communication module is used to request the system server to download the latest list to the smart door lock control device. If the system server has the latest list stored, it will be sent to the smart door lock control device, and it is determined whether the user account information matches the updated permission list. If the match is successful, an unlocking command is sent to the door lock control module, and the door lock control module controls the door lock to open or close. Furthermore, after each operation by the user, the smart door lock control device sends the collected card swiping data to the system server. The card swiping data includes but is not limited to user account information, smart door lock control device number, card swiping time, etc., to facilitate management personnel to manage usage data. It should be noted that the structure and working principle of the LoRa communication module can refer to the prior art, and this embodiment will not be repeated here.

[0045] As an option, the card reader module can also be a biometric card reader module, which is used to read the user's biometric information, including but not limited to fingerprint information, facial information, iris information, voiceprint information, etc. Correspondingly, the biometric information of the legitimate user needs to be stored in the first memory in advance. When unlocking is required, the biometric card reader module reads the user's biometric information, and then matches it with the biometric information of the legitimate user stored in the first memory. If the match is qualified, it means that the user is a legitimate user, and then sends an unlocking instruction to the door lock control module, and the door lock control module controls the door lock to open or close.

[0046] If there is no match, the LoRa communication module is used to request the system server to download the latest user's biometric information to the smart door lock control device. If the system server has stored the user's biometric information, it will be sent to the smart door lock control device and the user's biometric information will be matched with the updated biometric information. If they match, an unlocking command will be sent to the door lock control module, and the door lock control module will control the door lock to open or close.

[0047] It can be understood that the above-mentioned access control card and biometric information can be used in combination to improve the security of the smart door lock control device.

[0048] This embodiment obtains the user's user account information and first verifies it through the locally stored permission list. If the user information is locally available, an unlocking instruction is sent; if the user account information is not locally available, the system server is requested to download the latest list to the smart door lock control device through the LoRa communication module. If the system server has the latest list stored, it is downloaded to the smart door lock control device. The smart door lock control device determines whether the user account information matches the updated permission list. If it matches, an unlocking instruction is sent, thereby realizing data transmission using the LoRa communication module.

[0049] The process by which the system server determines whether the permission list matches is as follows:

[0050] The system server stores the permission list of each smart door lock control device, that is, each smart door lock control device has its own permission list. The system server will set the version number of each permission list, and change the version number every time the permission list is updated. The permission list sent by the system server to the smart door lock device also includes the corresponding version number. When the smart door lock device checks whether the permission list has been updated, the system server compares the version number of the permission list in the smart door lock device with the latest version number in the system server; if the version numbers are consistent, it means that the permission list has not been updated; if the version numbers are inconsistent, it means that the permission list has been updated.

[0051] Furthermore, as an option, when the system server determines whether the permission list matches, it can also compare the permission list in the system server with the permission list in the smart door lock control device one by one, that is, determine whether the two permission lists are consistent; if they are consistent, it means that the permission list has not been updated; if the version numbers are inconsistent, it means that the permission list has been updated.

[0052] Second embodiment

[0053] refer to Figure 2 On the basis of the first embodiment, the smart door lock control device based on LoRa communication in this embodiment further includes a Bluetooth module connected to the processor, used to connect to the mobile terminal and receive user account information sent by the mobile terminal. The user account information is pre-stored in the mobile terminal, and the user information is also stored in the permission list in the smart door lock control device and / or the system server. An APP for managing user account information is installed on the mobile terminal, so the mobile terminal can also be called an electronic access control card.

[0054] When unlocking is required, the mobile terminal connects to the smart door lock control device via Bluetooth, and sends the user account information to the smart door lock control device after the connection is successful. After receiving the user account information, the smart door lock control device first matches the user account information with the permission list stored locally in the smart door lock control device. When the user account information is matched, it means that the user is a legitimate user, and then sends an unlocking command to the door lock control module, and the door lock control module controls the door lock to open or close. If there is no match, the system server is requested to download the latest list to the smart door lock control device through the LoRa communication module. If the system server has the latest list stored, it will be sent to the smart door lock control device. The smart door lock control device searches and matches the user account information with the updated permission list. If the match is successful, the door lock control module controls the door lock to open or close. It should be noted that the structure and working principle of the Bluetooth module can refer to the prior art, and the present invention will not be repeated here.

[0055] As an option, the mobile terminal can obtain the user's biometric information, including but not limited to fingerprint information, facial information, iris information, voiceprint information, etc. Correspondingly, the biometric information of the legitimate user needs to be stored in the first memory in advance. When unlocking is required, the mobile terminal obtains the user's biometric information, and then transmits it to the smart door lock control device through the Bluetooth module, and matches it with the biometric information of the legitimate user stored in the first memory. If the match is qualified, it means that the user is a legitimate user, and then sends an unlocking command to the door lock control module, and the door lock control module controls the door lock to open or close.

[0056] If there is no match, the LoRa communication module is used to request the system server to download the latest user's biometric information to the smart door lock control device. If the system server has stored the latest user's biometric information, it will be sent to the local door lock. The smart door lock control device determines whether the user's biometric information matches the updated user's biometric information. If it matches, an unlocking command is sent to the door lock control module, and the door lock control module controls the door lock to open or close.

[0057] Preferably, the mobile terminal includes but is not limited to a smart phone, a smart watch, a tablet computer, etc.

[0058] In this embodiment, a mobile terminal is used to store user account information, and Bluetooth is used to transmit user account information, so that the user does not need to carry an access card with him. In addition, by obtaining the user's biometric information through the mobile terminal, the size and cost of the smart door lock control device can be reduced, and the user experience can be improved.

[0059] Third embodiment

Alternatively, two adjacent gateways can use different frequency bands to avoid mutual interference.

[0066] Furthermore, the system server can modify the permission list in the smart door lock control device, the mobile terminal, and the second memory. When a new user needs to be added, the user account information of the new user is written through the system server, and the system server can write the user account information of the new user into the access card and / or the mobile terminal and the second memory. When an existing user needs to be deleted, the system server sends a delete command to the smart door lock control device, the mobile terminal, and the second memory to perform the delete operation on the user to be deleted.

[0067] Furthermore, the system server processes the card swiping data uploaded by the smart door lock control device, forms statistical charts, and displays them on the monitor to facilitate management by the administrator.

An APP for managing user account information is installed on the mobile terminal, so the mobile terminal can also be called an electronic access control card.

[0072] When unlocking is required, the mobile terminal connects to the smart door lock control device via Bluetooth, and sends the user account information to the smart door lock control device after the connection is successful. After receiving the user account information, the smart door lock control device first matches the user account information with the permission list stored locally in the smart door lock control device. When the user account information is matched, it means that the user is a legitimate user, and then sends an unlocking command to the door lock control module, and the door lock control module controls the door lock to open or close. If there is no match, the system server is requested to download the latest list to the smart door lock control device through the LoRa communication module. If the system server has the latest list stored, it will be sent to the smart door lock control device. The smart door lock control device determines whether the user account information matches the updated permission list. If the match is successful, the door lock control module controls the door lock to open or close. It should be noted that the structure and working principle of the Bluetooth module can refer to the prior art, and the present invention will not be repeated here.

[0073] As an option, the mobile terminal can obtain the user's biometric information, including but not limited to fingerprint information, facial information, iris information, voiceprint information, etc. Correspondingly, the biometric information of the legitimate user needs to be stored in the first memory in advance. When unlocking is required, the mobile terminal obtains the user's biometric information, and then transmits it to the smart door lock control device through the Bluetooth module, and matches it with the biometric information of the legitimate user stored in the first memory. If the match is qualified, it means that the user is a legitimate user, and then sends an unlocking command to the door lock control module, and the door lock control module controls the door lock to open or close.

[0074] If there is no match, the LoRa communication module is used to request the system server to download the latest user's biometric information to the smart door lock control device. If the system server has the latest list stored, it will be sent to the local door lock. The smart door lock control device determines whether the user's biometric information matches the updated biometric information. If it matches, an unlocking command is sent to the door lock control module, and the door lock control module controls the door lock to open or close.

[0075] In this embodiment, the mobile terminal is equivalent to an electronic access control card. Considering that smartphones are now a must-have for everyone, the use of electronic access control cards allows users to no longer need to carry physical cards, thereby improving user experience.

[0076] refer to Figure 6 The present invention also provides a smart door lock control method based on LoRa communication, which is applied to the above-mentioned smart door lock control system and includes the following steps:

[0077] S1. Read the user account information of the access control card through the card reader module or receive the user account information sent by the mobile terminal through the Bluetooth module.

[0078] Specifically, if the smart door lock control device is in a dormant state, the smart door lock control device is awakened, and the user account information of the access card is read through the card reader module or the user account information sent by the mobile terminal is received through the Bluetooth module. The user account information is pre-stored in the access card and the mobile terminal. Alternatively, the card reader module can also be a biometric card reader module, which is used to read the user's biometric information, including but not limited to fingerprint information, facial information, iris information, voiceprint information, etc. Correspondingly, the biometric information of the legitimate user needs to be stored in the first memory in advance.

[0079] As an option, the mobile terminal may obtain the user's biometric information, including but not limited to fingerprint information, facial information, iris information, voiceprint information, etc. Correspondingly, the biometric information of the legitimate user needs to be stored in the first memory in advance.

[0080] S2. Determine whether the user account information is in the permission list of the smart door lock control device; the permission list includes a list of all users with door opening permissions. After the card reader module reads the user account information of the access card or receives the user account information sent by the mobile terminal through the Bluetooth module, the user account information is matched with the permission list. When the user account information is matched, it means that the user is a legitimate user, and then the unlocking command is sent to the door lock control module, and the door lock control module controls the door lock to open or close.

[0081] Alternatively, the card reader module may also be a biometric information card reader module, which is used to read the user's biometric information and determine whether the biometric information matches the biometric information of a legitimate user in the smart door lock control device.

[0082] Alternatively, the mobile terminal may obtain the user's biometric information, transmit the biometric information to the smart door lock control device via a Bluetooth module, and determine whether the biometric information matches the biometric information of a legitimate user in the smart door lock control device.

[0083] S3. If the user account information and / or biometric information contained in the permission list matches the biometric information of the legitimate user in the smart door lock control device, an unlocking command is issued, the door lock control module controls the door lock to open, and uploads the card swiping record information to the system server through the LoRa communication module.

[0084] S4. If the permission list does not contain the user account information or the biometric information does not match the biometric information of the legitimate user in the smart door lock control device, the system server is requested to download the latest list to the smart door lock control device through the LoRa communication module. If the system server has stored the latest list, it is downloaded to the smart door lock control device, and the smart door lock control device determines whether the user account information matches the updated permission list; and / or the system server is requested to download the biometric information of the latest user to the smart door lock control device. If the system server has stored the updated biometric information, it is sent to the smart door lock control device, and the smart door lock control device determines whether the user's biometric information matches the updated biometric information.

[0085] The process by which the system server determines whether the permission list matches is as follows:

[0086] The system server stores the permission list of each smart door lock control device, that is, each smart door lock control device has its own permission list. The system server will set the version number of each permission list, and change the version number every time the permission list is updated. The permission list sent by the system server to the smart door lock device also includes the corresponding version number. When the smart door lock device checks whether the permission list has been updated, the system server compares the version number of the permission list in the smart door lock device with the latest version number in the system server; if the version numbers are consistent, it means that the permission list has not been updated; if the version numbers are inconsistent, it means that the permission list has been updated.

[0087] Furthermore, as an option, when the system server determines whether the permission list matches, it can also compare the permission list in the system server with the permission list in the smart door lock control device one by one, that is, determine whether the two permission lists are consistent; if they are consistent, it means that the permission list has not been updated; if the version numbers are inconsistent, it means that the permission list has been updated.

[0088] S5. If it matches, an unlock command is sent to the door lock control module, and the door lock control module controls the door lock to open or close, and uploads the card swiping record information to the system server through the LoRa communication module. Specifically, if the user account information and / or biometric information contained in the permission list matches the latest permission list and / or the latest user's biometric information, an unlock command is issued, the door lock control module controls the door lock to open, and uploads the card swiping record information to the system server through the LoRa communication module. The smart door lock control device receives the unlock command, and the door lock control module controls the door lock to open. After the door lock is opened, the smart door lock control device sends the collected card swiping data to the system server. The card swiping data includes but is not limited to user account information, smart door lock control device number, card swiping time, etc., to facilitate the management personnel to manage the usage data. If the permission list does not contain user account information or the biometric information does not match the biometric information of the legitimate user in the system server, step S6 is executed, and the smart door lock control device enters sleep mode.

[0089] S6. The intelligent door lock control device enters sleep mode.

[0090] Furthermore, the LoRa communication-based intelligent door lock control method of the present invention further includes a voltage monitoring step:

[0092] Determine whether the detected voltage is less than a preset voltage; preferably, the alarm includes but is not limited to at least one of a buzzer, an audio player, and an indicator light.

[0093] If the detected voltage is less than the preset voltage, an alarm message is issued through the alarm, and / or the alarm message is sent to the system server through the LoRa communication module.

[0094] Furthermore, the LoRa communication-based smart door lock control method of the present invention also includes a time synchronization step:

[0095] Wake up the smart door lock control device at a preset time;

[0096] All smart door lock control devices request synchronization time in sequence according to the network address.
