DETAILED DESCRIPTION

[0022] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] In the description of the present invention, it should be noted that the orientations or positional relationships indicated by the terms "upper end", "interior", etc. are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0024] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "setting" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal connection of two elements, it can be a wireless connection, or it can be a wired connection. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0026] The remote sensing smart lock has a remote sensing distance of 3-4 meters. When a person walks to within 3-4 meters of the door, the radar wakes up the door lock, and the door lock and the remote sensing card perform data exchange verification. After the verification is passed, the unlocking action is executed. 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 the door inadvertently.

[0027] To solve the above technical problems, this embodiment provides a remote sensing smart lock, such as Figure 1As shown, it includes: a door lock assembly 1 installed at the door body, the door lock assembly 1 includes a main control circuit 2 arranged inside the lock body, the main control circuit 2 includes a microwave radar module 3, a Bluetooth module 4, a door lock plate 5, a round lock tongue 6 and an inclined tongue 7; the door lock plate 5 is installed in a door lock groove on the side of the door body, the door lock plate 5 is provided with a plurality of lock tongue holes, the inclined tongue 7 and the round lock tongue 6 are respectively arranged in the lock tongue holes from top to bottom, a first trigger 8 is arranged under the round lock tongue 6, a second trigger 9 is arranged under the inclined tongue 7, and the first trigger 8 and the second trigger 9 are respectively connected to the Bluetooth module 4.

[0028] Specifically, the microwave radar module 3 adopts a 24G microwave radar. The microwave radar module 3 performs motion detection. When there is human movement outside the door body, a wake-up signal is generated and the wake-up signal is transmitted to the Bluetooth module 4. In addition, when there is human movement outside the door body, the microwave radar module 3 detects the detection distance through radar technology reflection, that is, the distance between the door lock and the human body, obtains the detection signal, and continuously detects and collects the detection distance.

[0029] Specifically, before the Bluetooth module 4 is awakened, the round lock tongue 6 and the oblique lock tongue 7 are in a closed state; when the microwave radar module 3 detects human movement within 6-7 meters, a wake-up signal is sent to the Bluetooth module 4, and the Bluetooth module 4 controls the lock tongue to open 90%, not fully open, that is, using the first trigger signal, the first trigger 8 opens the round lock tongue 6, and the oblique lock tongue 7 does not move; the microwave radar module 3 continuously collects the detection distance and transmits the detection distance 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 body is willing to enter the room, and the lock system performs an unlocking execution action, that is, using the second trigger signal, the second trigger 9 opens the oblique lock tongue 7. At this time, the round lock tongue 6 and the oblique lock tongue 7 are both in an open state, and the door is opened when a person arrives.

[0030] Furthermore, if Figure 2 As shown, in response to the wake-up signal, the Bluetooth module 4 sends an opening signal to the first trigger 8 and the second trigger 9, and the first trigger 8 and the second trigger 9 control the round lock tongue 6 and the oblique tongue 7 to open; after a preset time interval, if no human body is detected in the room, the first trigger 8 and the second trigger 9 are controlled to lock the round lock tongue 6 and the oblique tongue 7.

[0031] Furthermore, when the lock is in the pre-unlocking 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) and the duration is more than 10 seconds, it indicates that the human body intends to leave, then the Bluetooth module 4 sends an anti-lock signal, and the first trigger 8 and the second trigger 9 execute the locking and anti-locking actions, and no longer performs the unlocking process.

[0032] A remote sensing smart lock provided in the present embodiment performs motion detection on human movement outside the door body through a microwave radar module, thereby realizing accurate detection of moving human bodies, and in response to a wake-up signal, only opens the round lock tongue, while the oblique tongue is in a closed state, thereby effectively avoiding unintentional unlocking caused by the user leaving halfway through unlocking the door, and ensuring that when the detection distance is less than the unlocking distance, both the round lock tongue and the oblique tongue are controlled to be in an open state, and the door lock is unlocked twice, thereby ensuring that when the user leaves halfway through unlocking the door lock, the door lock is still in a semi-closed state, thereby avoiding unintentional unlocking by the user, thereby improving the security of the remote sensing smart lock, and realizing the functions of the remote sensing smart lock that the door lock cannot be opened at a distance and cannot be opened at a close distance.

[0033] In some optional embodiments, a remote sensing controller 10 is further included which is arranged outside the door body;

[0034] The remote sensing controller 10 is arranged outside the door body, and the remote sensing controller 10 is wirelessly connected to the door lock assembly 1 .

[0035] Specifically, the remote sensing controller 10 can be a mobile phone (with a remote sensing SIM card), a remote access control, a remote sensing key, etc.

[0036] Furthermore, the remote sensing controller 10 uses a method of waking up the door lock assembly 1 by magnetic field induction. Since the propagation loss of the magnetic field in the air is very large, its sensing distance can be effectively controlled, which facilitates effective control of the recognition range of the magnetic field induction.

[0037] A remote sensing smart lock provided in this embodiment can effectively control the sensing distance by utilizing the interaction between the remote sensing controller and the door lock assembly, thereby facilitating effective control of the recognition range of the remote sensing controller.

[0038] In some optional embodiments, the door lock assembly 1 further includes an antenna 11;

[0039] The antenna 11 is connected to the remote sensing controller 10 and the Bluetooth module 4 , and is used for receiving the remote sensing data sent by the remote sensing controller 10 and transmitting the remote sensing data to the Bluetooth module 4 .

[0040] Specifically, the Bluetooth data of the Bluetooth module 4 is exchanged with the remote sensing controller 10 via the antenna 11 .

[0041] In some optional implementations, the Bluetooth module 4 includes:

[0042] The first Bluetooth chip 12 and the second Bluetooth chip 13 are connected.

[0043] 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, and then obtains the detection distance within a certain time period (for example, 10 seconds to 20 seconds), and then controls the first trigger 8 and the second trigger 9 to operate according to the detection distance to control the opening and closing of the door lock.

[0044] Furthermore, when the round lock tongue 6 and the oblique lock tongue 7 are both in the open state, and the remote sensing environment changes from outdoor to indoor, 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 anti-locking action.

[0045] Furthermore, the door lock assembly 1 also includes a voice broadcast module. If a door opener is not installed in the door body, the Bluetooth module 4 sends a broadcast instruction to the voice broadcast module, and the voice broadcast module broadcasts a preset voice 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 closed to control the door lock to perform an anti-locking action.

[0046] A remote sensing smart lock provided in this embodiment realizes accurate positioning of the user by identifying the remote sensing environment, and then 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.

[0047] In some optional embodiments, the Bluetooth module 4 further includes a power supply 14;

[0048] The power supply 14 is connected to the first Bluetooth chip 12 and the second Bluetooth chip 13 respectively.

[0049] In some optional embodiments, the antenna 11 includes a front lock plate antenna 15 arranged on one side of the door body and a rear lock plate antenna 16 arranged on the other side of the door body, 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.

[0050] Specifically, the front lock plate antenna 15 is arranged at the door body close to the outdoor side, and the rear lock plate antenna 16 is arranged at the door body close to the indoor side.

[0051] Furthermore, the front lock plate antenna 15 and the rear lock plate antenna 16 simultaneously receive the remote sensing signal sent by the remote sensing controller 10, and by comparing the signal strengths corresponding to the remote sensing signals received by the front lock plate antenna 15 and the rear lock plate antenna 16, when the signal strength received by the front lock plate antenna 15 is greater than the signal strength of the rear lock plate antenna 16, it indicates that the remote sensing controller 10 is outdoors at this time, that is, the moving person is outdoors; when the signal strength received by the front lock plate antenna 15 is less than the signal strength of the rear lock plate antenna 16, it indicates that the remote sensing controller 10 is indoors at this time, that is, the moving person is indoors.

[0052] A remote sensing smart lock provided in this embodiment realizes data transmission between a Bluetooth module and a remote sensing controller through a front lock plate antenna and a rear lock plate antenna, laying a foundation for accurate identification of subsequent remote sensing environments.

[0053] A method for unlocking a remote sensing smart lock is described below through a specific embodiment.

[0054] Embodiment 1:

[0055] When the user returns home, the lock radar senses the lock end and wakes up the lock end Bluetooth module through the microwave radar module. The Bluetooth data of the Bluetooth module is exchanged with the Bluetooth of the mobile phone with the SIM card installed (i.e. the mobile phone or remote sensing key) through the antenna. The Bluetooth module also recognizes and judges the user's indoor and outdoor conditions; performs pre-unlocking processing (open the round lock tongue, and the oblique lock tongue does not move);

[0056] 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 and performs the unlocking action. The user can open the door by approaching the door. After entering the door (if there is a door opener), the door will close automatically. If there is no door opener, the user will close the door by hand and the door will be locked through the lock system.

[0057] 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 anti-locking actions are performed, and the unlocking process is no longer performed.

[0058] Embodiment 2:

[0059] When the user returns to the door, the lock-end radar senses and verifies within 6-7 meters, and wakes up the lock-end Bluetooth module through the microwave radar module. The Bluetooth data of the Bluetooth module is exchanged with the Bluetooth of the mobile phone with the SIM card installed (i.e. the mobile phone or remote sensing key) through the antenna. The Bluetooth module also recognizes and judges the user's indoor and outdoor conditions, and performs unlocking (opening the round lock and the latch);

[0060] After 10 seconds, if the door opener does not operate, the door lock will automatically lock all the deadbolts.

[0061] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
