Description

Technical Field

[0001] This invention relates to the field of smart door lock technology, specifically to a remote sensing smart lock and its unlocking method. Background Technology

[0002] With the continuous advancement of IoT technology and the popularization of the smart home concept, smart locks have developed rapidly in recent years. Compared with traditional mechanical locks, smart locks have significant advantages in terms of convenience, security, and safety, but they still have some drawbacks: smart locks require active user operation, and forgetting to lock the door may pose a security threat; smart locks require power, and cannot be used if the power is insufficient; in addition, facial and fingerprint recognition technologies sometimes have errors, affecting the recognition rate, and if attacked by hackers, it may lead to the leakage of security information; furthermore, the wide contact surface of smart locks may also increase the risk of germ transmission.

[0003] With the development of remote sensing technology, remote sensing smart locks have solved the aforementioned defects of smart locks. However, since remote sensing smart locks require a certain amount of time to execute the unlocking action, if the user does not enter the room and turns around to leave within that time, the door will still be opened, resulting in the user unlocking the door unintentionally, which in turn leads to the low security of remote sensing smart locks. Summary of the Invention

[0004] In view of this, the present invention provides a remote sensing smart lock and its unlocking method to solve the problem of low security of remote sensing smart locks.

[0005] In a first aspect, the present invention provides a remote sensing smart lock, comprising: a door lock assembly installed at the door body, the door lock assembly including a main control circuit disposed inside the lock body, the main control circuit including a microwave radar module and a Bluetooth module;

[0006] The microwave radar module, connected to the Bluetooth module, is used to detect human movement outside the door, generate detection signals, and send a wake-up signal to the Bluetooth module based on the detection signals.

[0007] The Bluetooth module is used to perform pre-unlocking processing in response to the wake-up signal, and to determine the detection distance based on the detection signal, and to perform door lock opening and closing processing based on the detection distance.

[0008] This embodiment provides a remote sensing smart lock that uses a microwave radar module to detect human movement outside the door, achieving accurate detection of moving people. It responds to a wake-up signal to perform pre-unlocking processing and then performs door opening and closing processing based on the detection distance, unlocking the door twice. This ensures that the door remains partially closed when the user leaves during the unlocking process, improving the security of the remote sensing smart lock and realizing its function of not opening when the user is far away and opening when the user is close.

[0009] In one optional embodiment, the door lock assembly further includes: a door lock plate, a round latch, and a bevel latch; the door lock plate is installed in a door lock groove on the side of the door body, the door lock plate has multiple latch holes, the bevel latch and the round latch are respectively disposed in the latch holes from top to bottom, a first trigger is disposed under the round latch, a second trigger is disposed under the bevel latch, and the first trigger and the second trigger are respectively connected to the Bluetooth module.

[0010] In one optional implementation, the Bluetooth module is specifically configured to send a first trigger signal to a first trigger in response to a wake-up signal to open the round latch, and compare the detection distance with the unlocking distance. When the detection distance is less than the unlocking distance, it sends a second trigger signal to a second trigger to open the latch. When the first trigger opens the round latch in response to the first trigger signal, the latch is in a closed state.

[0011] This embodiment provides a remote sensing smart lock. The Bluetooth module controls the opening and closing of the first and second triggers through the first and second trigger signals, respectively, thereby realizing the opening and closing control of the round bolt and the latch. In response to the wake-up signal, only the round bolt is opened, while the latch remains closed. This effectively prevents unintentional unlocking caused by the user leaving midway through the unlocking process. It ensures that both the round bolt and the latch are opened only when the detection distance is less than the unlocking distance, thus improving the security of the remote sensing smart lock.

[0012] In an alternative implementation, the Bluetooth module is further configured to send a deadbolt signal to the first and second triggers when the detection distance is greater than the unlocking distance, so as to deadbolt the round bolt and the bevel bolt.

[0013] This embodiment provides a remote sensing smart lock. When the detection distance is greater than the unlocking distance, it indicates that the user has left during the unlocking process. Then, the first and second triggers can quickly lock the round bolt and the oblique bolt, effectively preventing unintentional unlocking caused by the user leaving during the unlocking process, improving the security of the remote sensing smart lock, and realizing the function of the remote sensing smart lock not opening when the distance is far and not opening when the distance is near.

[0014] In one alternative implementation, a remote sensing controller configured externally on the door is also included;

[0015] The remote control is installed on the outside of the door and is wirelessly connected to the door lock assembly.

[0016] This embodiment provides a remote sensing smart lock that utilizes the interaction between the remote sensing controller and the door lock components to effectively control the sensing distance and facilitates effective control of the remote sensing controller's recognition range.

[0017] In one alternative implementation, the door lock assembly further includes an antenna;

[0018] The antenna, connected to the remote sensing controller and Bluetooth module, is used to receive remote sensing data sent by the remote sensing controller and transmit the remote sensing data to the Bluetooth module.

[0019] In one alternative implementation, the Bluetooth module includes a first Bluetooth chip and a second Bluetooth chip, which are connected together.

[0020] The first Bluetooth chip is used to receive remote sensing data. When the remote sensing environment corresponding to the remote sensing data is outdoors, the door lock is opened or closed based on the detection distance.

[0021] The second Bluetooth chip is used to receive remote sensing data. When the remote sensing environment corresponding to the remote sensing data is indoors, it sends a lockout signal to the first and second triggers to execute the lockout action.

[0022] This embodiment provides a remote sensing smart lock that achieves accurate user location by recognizing the remote sensing environment. Consequently, the first Bluetooth chip and the second Bluetooth chip can quickly perform door lock opening and closing processing in the corresponding remote sensing environment, further improving the security of the remote sensing smart lock.

[0023] In one alternative implementation, the Bluetooth module further includes a power supply.

[0024] The power supply is connected to the first Bluetooth chip and the second Bluetooth chip respectively, and is used to provide operating power to the first Bluetooth chip and the second Bluetooth chip respectively.

[0025] In one optional embodiment, the antenna includes a front locking plate antenna disposed on one side of the door and a rear locking plate antenna disposed on the other side of the door. The front locking plate antenna is connected to a first Bluetooth chip, and the rear locking plate antenna is connected to a second Bluetooth chip.

[0026] This embodiment provides a remote sensing smart lock that enables data transmission between the Bluetooth module and the remote sensing controller through the front and rear locking plate antennas, laying the foundation for accurate identification of the subsequent remote sensing environment.

[0027] Secondly, the present invention provides a method for unlocking a remote sensing smart lock, applied to the aforementioned remote sensing smart lock, the method comprising:

[0028] The microwave radar module detects human movement outside the door, generates a detection signal, and sends a wake-up signal to the Bluetooth module based on the detection signal.

[0029] The Bluetooth module responds to the wake-up signal to perform pre-unlocking processing, determines the detection distance based on the detection signal, and performs door lock opening and closing processing based on the detection distance. Attached Figure Description

[0032] Figure 2 This is a schematic diagram of the structure of a door lock assembly according to an embodiment of the present invention;

[0033] Figure 3 This is a flowchart illustrating an unlocking method for a remote-sensing smart lock according to an embodiment of the present invention. Detailed Implementation

[0034] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] The remote sensing distance of the smart lock is 3-4 meters. When a person walks 3-4 meters away from the door, the radar wakes up the lock. The lock and the remote sensing card exchange data for verification. If the verification is successful, the unlocking action is started. However, the unlocking time is about 3 seconds. If the user does not enter the room and turns around to leave at this time, the door will still be opened, causing the user to unlock it unintentionally.

[0036] To address the aforementioned technical problems, this invention provides a remote sensing smart lock.

[0037] This embodiment provides a remote-sensing smart lock, which is used to implement the above embodiments and preferred embodiments; details already described will not be repeated. As used below, the term "module" can refer to a combination of software and / or hardware that implements a predetermined function. Although the device described in the following embodiments is preferably implemented in software, hardware implementation, or a combination of software and hardware, is also possible and contemplated.

[0038] This embodiment provides a remote sensing smart lock, such as Figure 1 As shown, it includes: a door lock assembly 1 installed at the door body, the door lock assembly 1 including a main control circuit 2 set inside the lock body, the main control circuit 2 including a microwave radar module 3 and a Bluetooth module 4;

[0039] The microwave radar module 3 is connected to the Bluetooth module 4 and is used to detect human movement outside the door, generate a detection signal, and send a wake-up signal to the Bluetooth module 4 based on the detection signal.

[0040] Specifically, the microwave radar module 3 uses a 24G microwave radar. The microwave radar module 3 performs motion detection. When there is human movement outside the door, it generates a wake-up signal and transmits the wake-up signal to the Bluetooth module 4. In addition, when there is human movement outside the door, the microwave radar module 3 uses radar technology to reflect and detect the detection distance, that is, the distance between the door lock and the human body, to obtain the detection signal, and continuously detects and collects the detection distance.

[0041] Bluetooth module 4 is used to perform pre-unlocking processing in response to a wake-up signal, determine the detection distance based on the detection signal, and perform door lock opening and closing processing based on the detection distance.

[0042] This embodiment provides a remote sensing smart lock that uses a microwave radar module to detect human movement outside the door, achieving accurate detection of moving people. It responds to a wake-up signal to perform pre-unlocking processing and then performs door opening and closing processing based on the detection distance, unlocking the door twice. This ensures that the door remains partially closed when the user leaves during the unlocking process, improving the security of the remote sensing smart lock and realizing its function of not opening when the user is far away and opening when the user is close.

[0043] In some alternative implementations, such as Figure 2 As shown, the door lock assembly 1 further includes: a door lock plate 5, a round latch 6, and a beveled latch 7; the door lock plate 5 is installed in the door lock groove on the side of the door body, the door lock plate 5 has multiple latch holes, the beveled latch 7 and the round latch 6 are respectively arranged in the latch holes from top to bottom, a first trigger 8 is arranged under the round latch 6, and a second trigger 9 is arranged under the beveled latch 7, the first trigger 8 and the second trigger 9 are respectively connected to the Bluetooth module 4.

[0044] Specifically, the Bluetooth module 4 controls the opening and closing of the first trigger 8 and the second trigger 9, thereby controlling the round latch 6 and the oblique latch 7 to perform opening and closing actions.

[0045] In some optional implementations, the Bluetooth module 4 is specifically used to send a first trigger signal to the first trigger 8 in response to a wake-up signal to open the round latch 6, and to compare the detection distance with the unlocking distance. When the detection distance is less than the unlocking distance, it sends a second trigger signal to the second trigger 9 to open the latch 7. When the first trigger 8 opens the round latch 6 in response to the first trigger signal, the latch 7 is in a closed state.

[0046] Specifically, before the Bluetooth module 4 is woken up, the round latch 6 and the bevel latch 7 are in the closed state. When the microwave radar module 3 detects human movement within 6-7 meters, it sends a wake-up signal to the Bluetooth module 4. The Bluetooth module 4 controls the latch to open 90%, not fully open. That is, using the first trigger signal, the first trigger 8 opens the round latch 6, while the bevel latch 7 remains inactive. The microwave radar module 3 continuously collects the detection distance and transmits it to the Bluetooth module 4. When the radar detects that the distance between the user and the door is within 1.5 meters (or 0.4m-0.8cm), it indicates that the human intends to enter the room. The lock system then performs the unlocking action, that is, using the second trigger signal, the second trigger 9 opens the bevel latch 7. At this time, both the round latch 6 and the bevel latch 7 are in the open state, realizing that the door opens when a person arrives.

[0047] Furthermore, in response to the wake-up signal, the Bluetooth module 4 sends an open signal to the first trigger 8 and the second trigger 9, and the first trigger 8 and the second trigger 9 control the round latch 6 and the oblique latch 7 to open; after a preset time interval, if no human body is detected entering the room, the first trigger 8 and the second trigger 9 control the round latch 6 and the oblique latch 7 to lock completely.

[0048] This embodiment provides a remote sensing smart lock. The Bluetooth module controls the opening and closing of the first and second triggers through the first and second trigger signals, respectively, thereby realizing the opening and closing control of the round bolt and the latch. In response to the wake-up signal, only the round bolt is opened, while the latch remains closed. This effectively prevents unintentional unlocking caused by the user leaving midway through the unlocking process. It ensures that both the round bolt and the latch are opened only when the detection distance is less than the unlocking distance, thus improving the security of the remote sensing smart lock.

[0049] In some alternative implementations, the Bluetooth module 4 is also used to send a deadbolt signal to the first trigger 8 and the second trigger 9 when the detection distance is greater than the unlocking distance, so as to deadbolt the round latch 6 and the oblique latch 7.

[0050] Specifically, when the lock is in a pre-unlocked state, and the microwave radar module 3 detects that the distance between the human body and the door is more than 1.5 meters (or more than 1 meter) for more than 10 seconds, it indicates that the human body intends to leave. Then the Bluetooth module 4 sends a deadbolt signal, and the first trigger 8 and the second trigger 9 perform the locking and deadbolt actions, and no longer perform the unlocking process.

[0051] This embodiment provides a remote sensing smart lock. When the detection distance is greater than the unlocking distance, it indicates that the user has left during the unlocking process. Then, the first and second triggers can quickly lock the round bolt and the oblique bolt, effectively preventing unintentional unlocking caused by the user leaving during the unlocking process, improving the security of the remote sensing smart lock, and realizing the function of the remote sensing smart lock not opening when the distance is far and not opening when the distance is near.

[0052] In some alternative implementations, a remote sensing controller 10 configured externally on the door body is also included;

[0053] The remote sensor controller 10 is installed outside the door and is wirelessly connected to the door lock assembly 1.

[0054] Specifically, the remote sensing controller 10 can be a mobile phone (with a remote sensing SIM card), a remote access control system, or a remote sensing key, etc.

[0055] Furthermore, the remote sensing controller 10 uses a magnetic field sensing method to wake up the door lock assembly 1. Since the magnetic field suffers great propagation loss in the air, its sensing distance can be effectively controlled, which facilitates the effective control of the magnetic field sensing recognition range.

[0056] This embodiment provides a remote sensing smart lock that utilizes the interaction between the remote sensing controller and the door lock components to effectively control the sensing distance and facilitates effective control of the remote sensing controller's recognition range.

[0057] In some alternative implementations, the door lock assembly 1 further includes an antenna 11;

[0058] Antenna 11 is connected to remote sensing controller 10 and Bluetooth module 4, and is used to receive remote sensing data sent by remote sensing controller 10 and transmit remote sensing data to Bluetooth module 4.

[0059] Specifically, the Bluetooth data of the Bluetooth module 4 is exchanged with the remote sensing controller 10 through the antenna 11.

[0060] In some alternative implementations, the Bluetooth module 4 includes a first Bluetooth chip 12 and a second Bluetooth chip 13, which are connected together.

[0061] The first Bluetooth chip 12 is used to receive remote sensing data. When the remote sensing environment corresponding to the remote sensing data is outdoors, the door lock is opened or closed based on the detection distance.

[0062] The second Bluetooth chip 13 is used to receive remote sensing data. When the remote sensing environment corresponding to the remote sensing data is indoors, it sends a lockout signal to the first trigger 8 and the second trigger 9 to perform a lockout action.

[0063] Specifically, when the remote sensing environment is outdoors, the first Bluetooth chip 12 continuously receives the detection signal sent by the microwave radar module 3, thereby obtaining the detection distance within a certain time period (e.g., 10 seconds to 20 seconds), and then controls the first trigger 8 and the second trigger 9 to operate according to the detection distance, so as to control the door lock to open and close.

[0064] Furthermore, when both the round latch 6 and the oblique latch 7 are in the open state, and the remote sensing environment changes from outdoors to indoors, indicating that a person has entered the door, the second Bluetooth chip 13 sends a closing command to the door opener, the door opener automatically closes the door, and controls the first trigger 8 and the second trigger 9 to close, so as to control the door lock to perform the deadbolt action.

[0065] Furthermore, the door lock component 1 also includes a voice broadcast module. If no door opener is installed in the door, the Bluetooth module 4 sends a broadcast command to the voice broadcast module, which then broadcasts a preset voice message to remind the user to close the door; or the Bluetooth module 4 sends a reminder to the mobile phone to remind the user to close the door. After the user closes the door, the first trigger 8 and the second trigger 9 are turned off to control the door lock to perform an anti-locking action.

[0066] This embodiment provides a remote sensing smart lock that achieves accurate user location by recognizing the remote sensing environment. Consequently, the first Bluetooth chip and the second Bluetooth chip can quickly perform door lock opening and closing processing in the corresponding remote sensing environment, further improving the security of the remote sensing smart lock.

[0067] In some alternative implementations, the Bluetooth module 4 also includes a power supply 14;

[0068] The power supply 14 is connected to the first Bluetooth chip 12 and the second Bluetooth chip 13 respectively, and is used to provide working power to the first Bluetooth chip 12 and the second Bluetooth chip 13 respectively.

[0069] In some alternative implementations, the antenna 11 includes a front lock plate antenna 15 disposed on one side of the door and a rear lock plate antenna 16 disposed on the other side of the door. The front lock plate antenna 15 is connected to the first Bluetooth chip 12, and the rear lock plate antenna 16 is connected to the second Bluetooth chip 13.

[0070] Specifically, the front lock plate antenna 15 is located on the door body near the outside, and the rear lock plate antenna 16 is located on the door body near the inside.

[0071] Furthermore, the front locking antenna 15 and the rear locking antenna 16 simultaneously receive remote sensing signals sent by the remote sensing controller 10. By comparing the signal strengths of the remote sensing signals received by the front locking antenna 15 and the rear locking antenna 16, if the signal strength received by the front locking antenna 15 is greater than the signal strength received by the rear locking antenna 16, it indicates that the remote sensing controller 10 is outdoors, i.e., the moving human body is outdoors; if the signal strength received by the front locking antenna 15 is less than the signal strength received by the rear locking antenna 16, it indicates that the remote sensing controller 10 is indoors, i.e., the moving human body is indoors.

[0072] This embodiment provides a remote sensing smart lock that enables data transmission between the Bluetooth module and the remote sensing controller through the front and rear locking plate antennas, laying the foundation for accurate identification of the subsequent remote sensing environment.

[0073] The following specific embodiments illustrate a method for unlocking a remote-sensing smart lock.

[0074] Example 1:

[0075] When a user returns home, the sensor on the lock's radar activates the lock's Bluetooth module via the microwave radar module. The Bluetooth module then exchanges data with the Bluetooth device on the phone (either the phone or the remote key) via the antenna. Simultaneously, the Bluetooth module identifies whether the user is indoors or outdoors and performs a pre-unlocking process (opening the round bolt while keeping the bolt inactive).

[0076] When the microwave radar module detects that the distance between the user and the door is within 1.5 meters, it indicates that the user intends to enter the room. The unlocking action is then initiated. The user can walk to the door and open it. After the user enters the door (if there is a door opener), the door will close automatically. If there is no door opener, the user can close the door manually. The door will then be locked by the locking system.

[0077] When the microwave radar module detects that the distance between the user and the door is more than 1.5 meters, it indicates that the user intends to leave the door, and the locking and deadbolting actions are executed, without attempting to unlock the door.

[0078] Example 2:

[0079] When a user returns home, the sensor lock's radar detects and verifies the user within 6-7 meters. The microwave radar module then wakes up the lock's Bluetooth module. The Bluetooth module's Bluetooth data is exchanged with the Bluetooth of a mobile phone with a SIM card installed (i.e., the mobile phone or remote key) via an antenna. The Bluetooth module simultaneously identifies whether the user is indoors or outdoors and initiates the unlocking process (opening the round lock and latch).

[0080] If the door opener does not move after 10 seconds, the door lock will automatically lock, engaging all latches.

[0081] According to an embodiment of the present invention, an embodiment of a remote sensing smart lock unlocking method is also provided. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

Figure 3 This is a flowchart of an unlocking method for a remote-sensing smart lock according to an embodiment of the present invention, as shown below. Figure 3 As shown, the process includes the following steps:

[0083] In step S301, the microwave radar module detects the movement of a human body outside the door, generates a detection signal, and sends a wake-up signal to the Bluetooth module based on the detection signal.

[0084] In step S302, the Bluetooth module responds to the wake-up signal to perform pre-unlocking processing, determines the detection distance based on the detection signal, and performs door lock opening and closing processing based on the detection distance.
