Description

Technical Field

[0001] The utility model relates to the technical field of intelligent door locks, and in particular to a door lock control device. Background Art

[0002] Smart door locks are becoming increasingly automated. These locks, relying on remote sensing technology, automatically unlock the door through data exchange between the door lock and a remote sensing card. However, there are many unusual apartment shapes on the market, such as L-shaped, recessed, and H-shaped units, as well as units with kitchens and bathrooms located near hallways. These complex units often block signals, making control difficult and incomplete. This can lead to accidental unlocking of unintended areas, resulting in a poor user experience.

[0003] Therefore, there is an urgent need for an intelligent door lock control device that can effectively distinguish remote sensing signals from inside and outside the door to solve the problem that traditional remote sensing intelligent locks are mistakenly unlocked when they are not intended to be unlocked. Utility Model Content

[0004] In view of this, the present application provides a door lock control device that can effectively distinguish remote sensing signals inside and outside the door. The technical solution is as follows.

[0005] The utility model provides a door lock control device, which comprises a radar unit, a remote sensing unit, a tag unit and a control unit.

[0006] The radar unit is used to collect relative position information of the target user and wake up the remote sensing unit according to the relative position information;

[0007] The remote sensing unit is configured to collect remote sensing signal data of the target user, wake up the control unit according to the remote sensing signal data of the target user, and send a first unlocking signal to the control unit;

[0008] The tag unit is arranged close to the door lock and is used to collect the remote sensing signal data of the target user and forward the second unlocking signal to the control unit through the remote sensing unit according to the remote sensing signal data of the target user;

[0009] The control unit is used to receive the first unlocking signal and / or the second unlocking signal. When the control unit receives the first unlocking signal and the second unlocking signal, the control unit controls the door lock to open; when the control unit receives the first unlocking signal or the second unlocking signal, the control unit controls the door lock to close.

[0010] The door lock control device provided by the utility model has the following advantages:

[0011] When a user is in a special indoor area of ​​an unusual apartment, such as a balcony, a downstairs corridor, or a kitchen, bathroom, or tea room near an outside walkway, the remote sensing smart door lock will recognize the remote sensing signal received from the user as an outdoor signal, thereby mistakenly unlocking the door. The door lock control device provided by the present invention provides a remote sensing tag in an area close to the door lock to perform secondary detection on the remote sensing signal sent by the user, thereby achieving three-way signal interaction between the target user's remote sensing key, the remote sensing smart door lock, and the remote sensing tag. The remote sensing tag detects the remote sensing signal data of the target user and generates a first unlocking signal and sends it to the control unit. The tag unit detects the remote sensing signal data of the target user and generates a second unlocking signal and forwards it to the control unit through the remote sensing unit. The remote sensing smart door lock control unit will only unlock the door when it receives the first unlocking signal and the second unlocking signal, that is, the remote sensing smart door lock will only unlock the door when the target user enters the signal receiving range of the remote sensing smart door lock and the remote sensing tag, thereby avoiding the situation where the remote sensing smart door lock mistakenly unlocks the door in special areas of unusual apartments.

[0012] In an optional embodiment, when the target user is outdoors, the control unit is able to receive the first unlocking signal and the second unlocking signal, so that the control unit controls the door lock to open; when the target user is indoors, the control unit can only receive the first unlocking signal or the second unlocking signal, and the control unit controls the door lock to close.

[0013] In an optional embodiment, the remote sensing unit is used to wake up the control unit and send a first unlocking signal to the control unit when the remote sensing signal data of the target user indicates that the target user is outdoors; when the remote sensing signal data of the target user indicates that the target user is indoors, the control unit is not woken up and the first unlocking signal is not sent to the control unit.

[0014] In an optional embodiment, the door lock control device further includes an antenna, which is connected to the remote sensing unit and is configured to receive remote sensing signal data of a target user and transmit the remote sensing signal data of the target user to the remote sensing unit.

[0022] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are 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 those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0023] In the description of the embodiments of the present application, the term "corresponding" may indicate a direct or indirect correspondence between the two, or an association relationship between the two, or a relationship between indication and being indicated, configuration and being configured, etc.

[0024] Smart door locks are smart home products that integrate electronics, integrated circuit design, a large number of electronic components, and a variety of innovative identification technologies (including computer network technology, built-in software cards, network alarms, and mechanical lock design). Unlike traditional mechanical locks, they use non-mechanical keys as user identification, providing greater intelligence in user identification, security, and management. With the development of remote sensing technology, remote sensing smart locks can automatically unlock the door based on data exchange between the door lock and the remote sensing card, allowing users to control the smart door lock more quickly and conveniently.

[0025] However, the market is flooded with unusual apartment designs, including L-shaped, concave, and H-shaped units, as well as units with kitchens and bathrooms located near hallways. These complex units often block signals, making control difficult and incomplete. Due to interference from these unit types, remote-sensing smart door locks cannot accurately distinguish whether a user's phone or remote key is indoors or outdoors, leading to accidental unlocking in areas where they shouldn't be, resulting in a poor user experience.

[0026] In order to solve the above problems, an embodiment of the present utility model provides an embodiment of a door lock control device.

[0027] In this embodiment, a door lock control device is provided, which is used to implement the above-mentioned embodiments and preferred embodiments. Details already described will not be repeated here. As used below, the term "unit" may refer to a combination of software and / or hardware that implements a predetermined function. Although the devices described in the following embodiments are preferably implemented in software, implementation using hardware, or a combination of software and hardware, is also possible and contemplated.

[0028] The door lock control device of this embodiment is as follows Figure 1 The system comprises: a radar unit, a remote sensing unit, a tag unit and a control unit.

[0029] The radar unit is used to collect the relative position information of the target user and wake up the remote sensing unit according to the relative position information.

[0030] Specifically, this relative position information includes the relative distance, horizontal angle, and vertical angle between the target user and the door lock. The radar unit is used for motion detection. When a person moves near the door lock, radar technology reflects the detected distance—that is, the relative distance between the door lock and the person—and generates a wake-up signal to wake up the door lock and its internal remote sensing unit and control unit. To prevent the radar unit from frequently waking up the door lock when a user approaches the door lock while indoors, the remote sensing unit can be placed on the outdoor side of the door to only detect outdoor user movement data. The radar unit's detection range can also be adjusted based on actual conditions such as the apartment layout.

[0031] The remote sensing unit is used to collect remote sensing signal data of the target user, wake up the control unit according to the remote sensing signal data of the target user, and send a first unlocking signal to the control unit.

[0032] Specifically, after the remote sensing unit is awakened, it will detect whether there is remote sensing signal data. The remote sensing signal data is a remote sensing signal emitted by the user's mobile phone or remote sensing key, and is matched with the pre-stored remote sensing signal of the target user. If the match is successful, it means that the target user needs to be unlocked, which will wake up the control unit and send the generated first unlocking signal to the control unit. Subsequently, the tag unit will perform a secondary detection of the target user's remote sensing signal data.

[0033] The tag unit is arranged close to the door lock, and is used to collect the remote sensing signal data of the target user, and forward the second unlocking signal to the control unit through the remote sensing unit according to the remote sensing signal data of the target user.

[0034] Specifically, the tag unit is set close to the door lock, which can be set indoors or outdoors. A second unlocking signal is generated based on the collected remote sensing signal data of the target user, and the second unlocking signal is forwarded to the control unit through the remote sensing unit. The target user remote sensing signal data here and the target user remote sensing signal data directly collected by the remote sensing unit are the same data, that is, the control unit can only unlock the door when both the remote sensing unit and the tag unit can detect the remote sensing signal data of the target user.

[0035] It should be noted that the indoor or outdoor mentioned here is relative to the smart door lock. The smart door lock is installed on the door body. The aisle area outside the door is the outdoors, and the residential area inside the door is the indoors. The tag unit is set in the accessories of the smart door lock and can be set indoors or outdoors. Because it provides remote sensing signal data for the tag unit to detect the target user, the detection range of the tag unit is basically the same.

[0036] A control unit is used to receive the first unlocking signal and / or the second unlocking signal. When the control unit receives the first unlocking signal and the second unlocking signal, the control unit controls the door lock to open; when the control unit receives the first unlocking signal or the second unlocking signal, the control unit controls the door lock to close.

[0037] Specifically, when the target user is outdoors, the control unit can receive the first unlocking signal and the second unlocking signal, so that the control unit controls the door lock to open; when the target user is indoors, the control unit can only receive the first unlocking signal or the second unlocking signal, and the control unit controls the door lock to close.

[0038] Optionally, the control unit opens some of the lock tongues of the smart door lock after receiving the first unlocking signal. If a second unlocking signal is received within a preset time, the remaining lock tongues of the smart door lock are opened; if no second unlocking signal is received at the end of the preset time, all the lock tongues in the smart door lock are closed.

[0039] In summary, the door lock control device provided in the embodiments of the present application has the following advantages:

[0040] When the user is in a special indoor area of ​​an irregular apartment, such as a balcony, a downstairs corridor, or a kitchen, bathroom, or tea room near the door, the remote sensing smart door lock will recognize the remote sensing signal received from the user as an outdoor signal, thereby mistakenly unlocking the door. The door lock control device provided by the present application sets a remote sensing tag in an area close to the door lock to perform secondary detection on the remote sensing signal sent by the user, thereby realizing a three-party signal interaction between the target user's remote sensing key, the remote sensing smart door lock, and the remote sensing tag. The remote sensing tag detects the remote sensing signal data of the target user and generates a first unlocking signal and sends it to the control unit. The tag unit detects the remote sensing signal data of the target user and generates a second unlocking signal and forwards it to the control unit through the remote sensing unit. The remote sensing smart door lock control unit will only unlock the door when it receives the first unlocking signal and the second unlocking signal, that is, it will only unlock the door when the target user enters the signal receiving range of the remote sensing smart door lock and the remote sensing tag, thereby avoiding the situation where the remote sensing smart door lock will be mistakenly unlocked in special areas of irregular apartments.

[0041] In some optional embodiments, the remote sensing unit is used to wake up the control unit and send a first unlocking signal to the control unit when the remote sensing signal data of the target user indicates that the target user is outdoors; and not wake up the control unit when the remote sensing signal data of the target user indicates that the target user is indoors.

[0042] Specifically, only when the target user's remote sensing signal comes from outdoors will the remote sensing unit perform a pre-unlocking operation to generate a first unlocking signal, wake up the control unit, and send the first unlocking signal to the control unit. If the target user's remote sensing signal data is received from indoors, the control unit will not be woken up, and the first unlocking signal will not be generated.

[0043] In an optional embodiment, the remote sensing unit is further used to verify the identity information of the target user based on the remote sensing signal data of the target user; when the identity information of the target user successfully matches the preset identity information, the control unit is awakened and a first unlocking signal is sent to the control unit.

[0044] Specifically, the identity information is a unique identification code of the target user pre-stored in the smart door lock, which is used to indicate the user identity and corresponds to the remote sensing signal data of the target user. The identity recognition module in the smart door lock can extract the corresponding identity information from the remote sensing signal data of the target user, and match the identity information with the pre-stored identity information of the target user. When the match is successful, it indicates that the collected remote sensing signal data is sent by the target user. At this time, the control unit will be awakened and a first unlocking signal will be generated, and the first unlocking signal will be sent to the control unit.

[0045] In an optional embodiment, the tag unit is further used to verify the identity information of the target user based on the remote sensing signal data of the target user; when the identity information of the target user successfully matches the preset identity information, the second unlocking signal is forwarded to the control unit through the remote sensing unit.

[0046] Specifically, the remote sensing unit also stores the identity information of the target user, which is consistent with the above-mentioned identity information and is used to match the detected remote sensing signal data of the target user. When the match is successful, it indicates that the collected remote sensing signal data is sent by the target user. At this time, a second unlocking signal will be generated and forwarded to the control unit through the remote sensing unit.

[0047] In some optional embodiments, the door lock control device further includes an antenna, which is connected to the remote sensing unit and is configured to receive remote sensing signal data of a target user and transmit the remote sensing signal data of the target user to the remote sensing unit.

[0048] Specifically, the target user's remote sensing data provides antennas and remote sensing units for data interaction.

[0049] In some optional embodiments, the antenna includes a front lock plate antenna and a rear lock plate antenna. The front lock plate antenna is located on the door body near the outdoor side, and the rear lock plate antenna is located on the door body near the indoor side. The front lock plate antenna and the rear lock plate antenna simultaneously receive remote sensing signal data of the target user to determine the target user's location area.

[0050] Specifically, by comparing the signal strengths corresponding to the remote sensing signals received by the front lock plate antenna and the rear lock plate antenna, when the signal strength received by the front lock plate antenna is greater than the signal strength received by the rear lock plate antenna, it indicates that the target user is outdoors at this time; when the signal strength received by the front lock plate antenna is less than the signal strength received by the rear lock plate antenna, it indicates that the target user is indoors at this time.

[0051] The door lock control device provided in this embodiment realizes data transmission between the target user's key and the remote sensing controller through the front lock plate antenna and the rear lock plate antenna, laying the foundation for accurate identification of the subsequent remote sensing environment.

[0052] The door lock control device in this embodiment is presented in the form of a functional unit, where the unit refers to an ASIC (Application Specific Integrated Circuit) circuit, a processor and memory that executes one or more software or fixed programs, and / or other devices that can provide the above functions.

[0053] The present application provides a door lock control method, which is applied to the above-mentioned door lock control device, such as Figure 2 As shown, the door lock control method includes:

[0054] Step S201: collecting relative position information of a target user through a radar unit, and waking up the remote sensing unit according to the relative position information.

[0055] Optionally, in step S201, the radar unit is configured to detect human motion, generate a detection signal, and send a wake-up signal to the remote sensing module based on the detection signal. Specifically, the radar unit transmits a detection signal and receives a feedback signal indicating that the detection signal has detected the target user. Based on the feedback signal, the relative distance between the target user and the door lock is determined. If the relative distance meets a threshold condition, it indicates that the target user has reached the pre-unlock position, waking up the remote sensing unit.

[0056] It should be noted that the threshold condition refers to a pre-set relative distance range, that is, when the relative distance between the target user and the radar unit is within the pre-set relative distance range, it means that an unlocking operation is required at this time, and the radar unit will wake up the remote sensing unit.

[0057] In the method of this embodiment, the radar unit can be directly set outside the door body to perform motion detection on human movements outside the door body. When there is human movement within the preset detection range of the radar unit, the radar unit will wake up the remote sensing unit according to the human movement situation, thereby avoiding waking up the remote sensing unit when the user is indoors, causing unnecessary waste of power.

[0058] Relative position information includes relative distance, horizontal angle, and vertical angle. This relative position information is acquired via a radar unit. Specifically, the radar unit transmits a detection signal and receives a feedback signal indicating that the detection signal has detected the target user. Based on the feedback signal, the relative distance between the target user and the door lock is determined. If the relative distance meets a threshold, the target user has reached the pre-unlock position, waking up the remote sensing unit.

[0059] Step S202 : collecting remote sensing signal data of the target user through the remote sensing unit, waking up the control unit according to the remote sensing signal data of the target user, and sending a first unlocking signal to the control unit.

[0060] Optionally, in step S202, after the remote sensing unit is awakened, the user identity information indicated by the received remote sensing signal data of the target user is matched with the preset identity information. When the identity information of the target user matches the preset identity information, a first unlocking signal is generated and the control unit is awakened, and the first unlocking signal is sent to the control unit. If the match cannot be successful, the control unit will not be awakened and the first unlocking signal will not be generated.

[0061] Step S203 , collecting remote sensing signal data of the target user through a tag unit provided close to the door lock, and forwarding a second unlocking signal to the control unit through the remote sensing unit according to the remote sensing signal data of the target user.

[0062] Optionally, in step S203, the tag unit verifies the identity information of the target user based on the remote sensing signal data sent by the target user within the preset range; when the identity information of the target user matches the preset identity information, the user information data is forwarded to the remote sensing unit; when the identity information of the target user does not match the preset identity information, the user information data is not forwarded. The preset range can be adjusted according to the actual apartment type. The tag unit is usually set at a position inside or outside the door close to the door lock accessories. The setting position of the tag unit can also be adjusted according to the actual apartment type so that the detection range of the tag unit can cover a certain range outside the door. Since the tag unit only forwards user signal data, the control unit will determine whether the range of the signal data is legal. Therefore, the tag unit only needs to detect the area outside the door, that is, the tag unit can be completely set outside the door and does not detect the remote sensing signal of the indoor area.

[0063] Step S204, the control unit receives the first unlocking signal and / or the second unlocking signal. When the control unit receives the first unlocking signal and the second unlocking signal, the control unit controls the door lock to open; when the control unit receives the first unlocking signal or the second unlocking signal, the control unit controls the door lock to close.

[0064] The door lock control method is described below through specific embodiments.

[0065] like Figure 3 As shown, the user is in an L-shaped apartment, which has a protruding area close to the aisle. Without a remote sensing tag, the smart door lock will recognize the remote sensing signal sent by the user's mobile phone or remote sensing key as being outdoors, and the smart door lock will unlock by mistake.

[0066] By setting a remote sensing tag close to the door lock and setting the sensing range of the remote sensing tag, the door will only be unlocked when the user is outside the door and within the sensing range of the remote sensing tag. When the user is in the protruding area of ​​the apartment, the user's mobile phone or remote sensing key will not be recognized by the remote sensing tag, and the door will not be unlocked by mistake.

[0067] In summary, the door lock control method provided by the present application is such that when a user is in a special indoor area of ​​an irregularly shaped apartment, such as a balcony, a downstairs corridor, a kitchen, a bathroom, or a tea room near the door, the remote sensing smart door lock will recognize the remote sensing signal received from the user as an outdoor signal, thereby mistakenly unlocking the door. The door lock control device provided by the present application, by setting a remote sensing tag in an area close to the door lock, performs secondary detection on the remote sensing signal sent by the user, and realizes a three-party signal interaction between the target user's remote sensing key, the remote sensing smart door lock, and the remote sensing tag. The remote sensing smart door lock will only unlock the door when it receives the remote sensing signal sent by the user and the confirmation signal sent by the remote sensing tag to the door lock. That is, the door lock will only unlock the door when the target user enters the signal receiving range of the remote sensing smart door lock and the remote sensing tag, thereby avoiding the situation where the remote sensing smart door lock will unlock the door by mistake in special areas of irregularly shaped apartments.

[0068] The present application also provides a computer device capable of implementing the above Figure 2 The door lock control method shown.
