Description

Technical Field

[0001] The present application relates to the technical field of smart door locks, and in particular to a method for activating a child lock function based on a smart door lock and a smart door lock. Background Art

[0002] With the continuous development of society and technology, more and more users are beginning to use smart door locks, and the safety issues of underage users using smart door locks indoors are becoming increasingly prominent. The traditional method of activating the child lock function is relatively simple and most of them require users to manually open it. When the user forgets to turn on the child lock function, the safety of underage users indoors cannot be guaranteed. Therefore, the present application proposes a child lock function activation method based on a smart door lock and a smart door lock.

[0003] Prior art, such as the invention patent application with announcement number: CN117727112A, discloses a smart door lock control method, system, storage medium and electronic device. The method is applied to a smart door lock equipped with an angle measurement module indoors, including: determining that the angle measurement module detects a target object within a first detection distance; determining the detection angle of the angle measurement module; determining the height of the target object according to the detection angle, the pre-stored first detection distance and the installation height of the angle measurement module from the ground; if the height is less than the preset door opening height threshold, then controlling the smart door lock to remain locked when receiving the door opening request from the target object. This method can effectively prevent children from opening the door and going out alone, and compared with the mechanical child lock structure that children can easily learn how to unlock, the present invention adopts intelligent collection and analysis methods and technologies, which are difficult for children to crack and have high stability, and can significantly reduce the risk of children getting lost or having accidents in the corridor.

[0004] With respect to the above scheme, the inventors of the present application have at least discovered that the above technology has at least the following technical problems: 1. The current technology mainly determines the locked state of the smart door lock by detecting the height of the target object within the first detection distance through the angle measurement module, and lacks detection of other information of the target object. When the target object is a child and is taller than the parent indoors, the smart door lock cannot effectively prevent the child from opening the door and going out alone, and thus cannot ensure the safety of children indoors, nor can it reflect the rationality of the smart door lock.

[0005] 2. The current technology lacks analysis of follow-up measures after the child lock function is activated. After the child lock function is activated, there is no timely reminder to parents, which cannot avoid the risk of children getting lost or having accidents in the corridor after violently breaking the lock. In addition, the smart door lock has a single function and cannot meet the usage needs of different users. Summary of the invention

[0006] The purpose of this application is to provide a method for activating a child lock function based on a smart door lock and a smart door lock, which solves the problems existing in the background technology.

[0007] To solve the above technical problems, the present application adopts the following technical solutions: In the first aspect, the present application provides a method for starting a child lock function based on a smart door lock, comprising the following steps: Step 1, detecting the total number of adult users in the room through the first detection unit on the smart door lock, and then determining whether there are adult users in the room.

[0008] Step 2: When there is an adult user in the room and the user turns the door handle connected to the smart door lock to open the door, the second detection unit on the door handle of the smart door lock obtains the pressure value and palm print information value of the user applying the door handle, and then analyzes and obtains the door opening evaluation coefficient of the user to determine whether the child lock function needs to be activated.

[0009] Step 3: When there is no adult user in the room, the smart door lock activates the child lock function. At the same time, the third detection unit detects whether a minor user in the room is close to the smart door lock, and determines whether an early warning prompt is needed.

[0010] Preferably, the first detection unit on the smart door lock includes a second detection unit, a third detection unit, a storage unit and a first judgment unit. The first detection unit stores the total number of adult users in the room through the storage unit, and judges whether there are adult users in the room through the first judgment unit; the second detection unit includes a pressure sensor, a palm print sensor and a second judgment unit. The second detection unit obtains the pressure value and palm print information value acting on the door handle when the door opening user turns the door handle connected to the smart door lock through the pressure sensor and the palm print sensor, respectively, and judges whether the smart door lock needs to activate the child lock function through the second judgment unit; the third detection unit includes an infrared sensor and a third judgment unit. The third detection unit measures the straight-line distance between the underage user in the room and the smart door lock through the infrared sensor, and judges whether the smart door lock needs to issue an early warning prompt through the third judgment unit.

[0011] Preferably, the functions of the smart door lock after the child lock is activated include a smart door lock single locking function and a smart door lock double locking function.

[0012] When the first detection unit of the smart door lock detects that there is an adult user in the room, the number of times the child lock function is activated within the set time period is recorded as , , The total number of times the child lock function is activated within the set time period, set according to the calculation formula: Get the frequency representative value of starting the child lock function ,in It is the threshold of the number of times the child lock function is activated within the set time period in the database. When the smart door lock activates the child lock, the function is double locking. When the child lock is activated, the smart door lock functions as a single lock.

[0013] When the first detection unit of the smart door lock detects that there is no adult user in the room, the function of the smart door lock after activating the child lock is a double locking function.

[0014] Preferably, the single locking function of the smart door lock after the child lock is activated includes locking the palm print sensor on the door handle of the smart door lock, so that the user who opens the door cannot open the door through the door handle of the smart door lock. At this time, the adult user opens the door through the face recognition method on the smart door lock.

[0015] The double locking function of the smart door lock after the child lock is activated includes locking all door opening methods of the smart door lock. The door can only be opened after an adult user performs the corresponding unlocking operation on the smart door lock.

[0016] Preferably, the smart door lock early warning prompt includes a first early warning prompt and a second early warning prompt.

[0017] The first warning prompt includes a voice warning prompt to an indoor underage user who intends to approach the smart door lock until the indoor underage user moves away from the smart door lock.

[0018] The second warning prompt includes a voice prompt to the indoor underage user who intends to approach the smart door lock, and a mobile phone terminal warning prompt to the adult user, until the indoor underage user moves away from the smart door lock or the adult user controls the smart door lock to perform corresponding operations.

[0019] Preferably, the third detection unit is used to detect whether the indoor underage user is close to the smart door lock, and to determine whether an early warning prompt is required. The specific detection and judgment process is as follows: the straight-line distance value between the indoor underage user and the smart door lock detected by the third detection unit is recorded as , set according to the calculation formula Get the door opening intention value of the indoor underage user ,in and They are respectively represented as the upper threshold of the straight-line distance between an indoor underage user and the smart door lock in the database and the lower threshold of the straight-line distance between an indoor underage user and the smart door lock.

[0020] like , then the indoor underage user detected by the third detection unit is not close to the smart door lock; if , then the third detection unit detects that the indoor underage user has the intention to approach the smart door lock; if , the third detection unit detects that the indoor underage user has approached the smart door lock.

[0021] When the third detection unit detects that the indoor underage user is not approaching the smart door lock, it is judged that the smart door lock does not issue a warning prompt; when the third detection unit detects that the indoor underage user has the intention to approach the smart door lock, it is judged that the smart door lock issues a first warning prompt to the user who opens the door; when the third detection unit detects that the indoor underage user is already approaching the smart door lock, it is judged that the smart door lock issues a first warning prompt to the indoor underage user and a second warning prompt to the adult user at the same time.

[0022] In a second aspect, the present application provides a smart door lock, including: a first detection unit: the first detection unit on the smart door lock detects the total number of adult users in the room, and then determines whether there are adult users in the room.

[0023] Second detection unit: When there is an adult user in the room and the user turns the door handle connected to the smart door lock to open the door, the second detection unit on the door handle of the smart door lock obtains the pressure value and palm print information value applied to the door handle by the user who opens the door, and then analyzes and obtains the door opening evaluation coefficient of the user who opens the door to determine whether the child lock function needs to be activated.

[0024] The third detection unit: When there is no adult user in the room, the smart door lock activates the child lock function. At the same time, the third detection unit detects whether a minor user in the room is close to the smart door lock, and determines whether an early warning prompt is needed.

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, an indirect connection through an intermediate medium, or the internal connection of two components; for those skilled in the art, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0035] Reference Figure 1 As shown, the present application provides a method for starting a child lock function based on a smart door lock in the first aspect, comprising the following steps: Step 1, detecting the total number of adult users in the room through a first detection unit on the smart door lock, and then determining whether there are adult users in the room.

[0036] In a specific example, the first detection unit on the smart door lock includes a second detection unit, a third detection unit, a storage unit and a first judgment unit. The first detection unit stores the total number of adult users in the room through the storage unit, and judges whether there are adult users in the room through the first judgment unit; the second detection unit includes a pressure sensor, a palm print sensor and a second judgment unit. The second detection unit obtains the pressure value and palm print information value acting on the door handle when the door opening user turns the door handle connected to the smart door lock through the pressure sensor and the palm print sensor, respectively, and judges whether the smart door lock needs to activate the child lock function through the second judgment unit; the third detection unit includes an infrared sensor and a third judgment unit. The third detection unit measures the straight-line distance between the underage user in the room and the smart door lock through the infrared sensor, and judges whether the smart door lock needs to issue an early warning prompt through the third judgment unit.

[0037] In a specific example, the first detection unit on the smart door lock detects the total number of adult users in the room, and then determines whether there are adult users in the room. The specific detection and judgment process is as follows: the number of adult users entering and exiting each time detected by the smart door lock within the set time period and the preset total number of adult users are recorded as and When the smart door lock is opened from indoors, The number of adult users who go out for the and When the smart door lock is opened from indoors, Number of adult users who went out Recorded as When the smart door lock is opened from outside, Number of adult users entering indoor spaces Recorded as , It is represented by the number of adult users who pass through when the smart door lock is opened. , is an integer greater than 2, It indicates the number of times the smart door lock is opened within the set time period. , is an integer greater than 2, Indicates the total number of times the smart door lock is opened within the set time period, according to the calculation formula Get the total number of existing adult users indoors and record it in the storage unit.

[0038] when When the first detection unit determines that there is no adult user in the room.

[0039] when When the user enters the room, the first detection unit determines that there is an adult user in the room.

[0040] It should be noted that the preset total number of adult users is the total number of indoor adult users pre-entered by the user and stored in the storage device before using the smart door lock.

[0041] It should be noted that the total number of adult users entering and leaving the smart door lock within a set time period is detected by an infrared sensor installed on the smart door lock and recorded in a storage unit.

[0042] Step 2: When there is an adult user in the room and the user turns the door handle connected to the smart door lock to open the door, the second detection unit on the door handle of the smart door lock obtains the pressure value and palm print information value of the user applying the door handle, and then analyzes and obtains the door opening evaluation coefficient of the user to determine whether the child lock function needs to be activated.

[0043] In a specific example, the analysis obtains the door opening evaluation coefficient of the door opening user. The specific analysis process is as follows: the pressure value and palm print information value acting on the door handle when the door opening user turns the door handle connected to the smart door lock are recorded as and , set according to the calculation formula: Get the door opening evaluation coefficient of the door opening user ,in and They respectively represent the standard value of pressure and the standard value of palm print information acting on the door handle when the door opener turns the door handle connected to the smart door lock, which are set in the database. and They are respectively represented as the weight factor corresponding to the pressure value acting on the door handle when the door opening user in the database turns the door handle connected to the smart door lock and the weight factor corresponding to the palm print information value.

[0044] It should be noted that the palm print information value obtained is the consistency between the palm print patterns of the door-opening user and the palm print patterns of the indoor underage user pre-input into the smart door lock and stored in the storage device. When the palm print patterns of the door-opening user are consistent with the palm print patterns of the indoor underage user pre-input into the smart door lock and stored in the storage device, the palm print information value of the door-opening user is recorded as 1, otherwise the palm print information value of the door-opening user is recorded as 0.

[0045] It should be noted that the standard value of pressure applied to the door handle when the door opening user turns the door handle connected to the smart door lock set in the database is the maximum pressure when an underage user indoors turns the door handle connected to the smart door lock; the standard value of palm print information applied to the door handle when the door opening user turns the door handle connected to the smart door lock set in the database is the palm print value of the underage user indoors that is pre-input into the smart door lock and stored in the storage device.

[0046] It should be noted that , , .

[0047] It should be noted that the correction factor corresponding to the pressure value acting on the door handle when the door opener turns the door handle connected to the smart door lock and the correction factor corresponding to the palm print information value are obtained by the correction factor analysis method. First, the original data of the pressure value and the palm print information value acting on the door handle when the door opener turns the door handle connected to the smart door lock are obtained multiple times, and the average value is taken after removing the maximum and minimum values, and then the correction factor is obtained by dividing the original data of the pressure value and the palm print information value acting on the door handle when the door opener turns the door handle connected to the smart door lock by the median after removing the maximum and minimum values.

[0048] It should be noted that factor analysis is a well-known technology. It is a multivariate statistical analysis method that starts from studying the internal dependencies of variables and reduces some variables with intricate relationships to a few comprehensive factors; information concentration is expressed as calculating the median; the variance explanation rate is the amount of information extracted by the factor, and the variance explanation rate = characteristic root / total number of analysis items; the variance explanation rate after rotation is expressed as the variance explanation rate of the factor after maximum variance rotation.

[0049] In a specific example, the determination of whether the child lock function needs to be activated is specifically carried out as follows: comparing the door opening evaluation coefficient of the door opening user with the standard value of the door opening evaluation coefficient of the door opening user in the database; when the ratio of the door opening evaluation coefficient of the door opening user to the standard value of the door opening evaluation coefficient of the door opening user in the database is within the interval [0.8,1], it is determined that the child lock function needs to be activated; otherwise, it is determined that the child lock function does not need to be activated.

[0050] It should be noted that when an underage user indoors turns the door handle connected to the smart door lock to open the door, the first detection unit of the smart door lock detects the maximum pressure value acting on the door handle and when the palm print information value of the door opening user is 1, the door opening evaluation coefficient of the door opening user obtained by analysis is used as the standard value of the door opening evaluation coefficient of the door opening user in the database.

[0051] Step 3: When there is no adult user in the room, the smart door lock activates the child lock function. At the same time, the third detection unit detects whether a minor user in the room is close to the smart door lock, and determines whether an early warning prompt is needed.

[0052] In a specific example, the functions of the smart door lock after the child lock is activated include a single locking function of the smart door lock and a double locking function of the smart door lock; when the first detection unit of the smart door lock detects that there is an adult user in the room, the number of times the child lock function is activated within a set time period is recorded as , , The total number of times the child lock function is activated within the set time period, set according to the calculation formula: Get the frequency representative value of starting the child lock function ,in It is the threshold of the number of times the child lock function is activated within the set time period in the database. When the smart door lock activates the child lock, the function is double locking. When the child lock is activated, the smart door lock functions as a single lock.

[0053] When the first detection unit of the smart door lock detects that there is no adult user in the room, the function of the smart door lock after activating the child lock is a double locking function.

[0054] It should be noted that the threshold of the number of times the child lock function is activated within a set time period in the database is set by the adult user. For example, the threshold is reached if the child lock function is activated three times within five minutes.

[0055] In a specific example, the single locking function of the smart door lock after the child lock is activated includes locking the palm print sensor on the door handle of the smart door lock, and the user who opens the door cannot open the door through the door handle of the smart door lock. At this time, the adult user opens the door through the face recognition method on the smart door lock.

[0056] The double locking function of the smart door lock after the child lock is activated includes locking all door opening methods of the smart door lock. The door can only be opened after an adult user performs the corresponding unlocking operation on the smart door lock.

[0057] It should be noted that the unlocking operation method of the dual locking function of the smart door lock after the child lock is activated is set by the adult user, such as password unlocking, adult user face recognition unlocking, or remote control unlocking by mobile phone.

[0058] In a specific example, the smart door lock early warning prompt includes a first early warning prompt and a second early warning prompt.

[0059] The first warning prompt includes a voice warning prompt to an indoor underage user who intends to approach the smart door lock until the indoor underage user moves away from the smart door lock.

[0060] The second warning prompt includes a voice prompt to the indoor underage user who intends to approach the smart door lock, and a mobile phone terminal warning prompt to the adult user, until the indoor underage user moves away from the smart door lock or the adult user controls the smart door lock to perform corresponding operations.

[0061] It should be noted that the content of the voice warning prompts for indoor underage users is set by adult users and can be changed.

[0062] It should be noted that the method of providing mobile terminal warning prompts to adult users is set by the adult users themselves and can be changed, such as text message warnings or mobile phone ringtone warnings.

[0063] In a specific example, the third detection unit is used to detect whether an indoor underage user is close to the smart door lock, and to determine whether an early warning prompt is required. The specific detection and judgment process is as follows: the straight-line distance between the indoor underage user and the smart door lock detected by the third detection unit is recorded as , set according to the calculation formula: Get the door opening intention value of the indoor underage user ,in and They are respectively represented as the upper threshold of the straight-line distance between an indoor underage user and the smart door lock in the database and the lower threshold of the straight-line distance between an indoor underage user and the smart door lock.

[0064] like , then the indoor underage user detected by the third detection unit is not close to the smart door lock; if , then the third detection unit detects that the indoor underage user has the intention to approach the smart door lock; if , the third detection unit detects that the indoor underage user has approached the smart door lock.

[0065] When the third detection unit detects that the indoor underage user is not approaching the smart door lock, it is judged that the smart door lock does not issue a warning prompt; when the third detection unit detects that the indoor underage user has the intention to approach the smart door lock, it is judged that the smart door lock issues a first warning prompt to the user who opens the door; when the third detection unit detects that the indoor underage user is already approaching the smart door lock, it is judged that the smart door lock issues a first warning prompt to the indoor underage user and a second warning prompt to the adult user at the same time.

[0066] Reference Figure 2 As shown, the present application provides a smart door lock in the second aspect, including: a first detection unit: the total number of adult users in the room is detected by the first detection unit on the smart door lock, and then it is determined whether there are adult users in the room.

[0067] Second detection unit: When there is an adult user in the room and the user turns the door handle connected to the smart door lock to open the door, the second detection unit on the door handle of the smart door lock obtains the pressure value and palm print information value applied to the door handle by the user who opens the door, and then analyzes and obtains the door opening evaluation coefficient of the user who opens the door to determine whether the child lock function needs to be activated.

[0068] The third detection unit: When there is no adult user in the room, the smart door lock activates the child lock function. At the same time, the third detection unit detects whether a minor user in the room is close to the smart door lock, and determines whether an early warning prompt is needed.

[0069] The present application provides a method for activating a child lock function based on a smart door lock and a smart door lock. The method detects the total number of adult users in the room through a first detection unit on the smart door lock, and then determines whether there are adult users in the room. The door opening information of the user who opens the door when there are adult users in the room is analyzed, and then it is determined whether to activate the child lock function. Finally, the door opening intention of the underage user in the room when there are no adult users in the room is analyzed, so as to provide early warning prompts in time. At the same time, the number of child lock activations within a set time period is detected, and different child lock functions are activated according to the unlocking situation of the underage users in the room, thereby effectively ensuring the safety and stability of the smart door lock, reducing the safety problems caused by the unauthorized unlocking of the underage users in the room, and at the same time meeting the usage needs of different users.

[0070] The above contents are merely examples and explanations of the concept of the present application.

A method for activating a child lock function based on a smart door lock according to claim 5, characterized in that: The functions of the smart door lock after the child lock is activated include a smart door lock single locking function and a smart door lock double locking function; When the first detection unit of the smart door lock detects that there is an adult user in the room, the number of times the child lock function is activated within the set time period is recorded as , , The total number of times the child lock function is activated within the set time period is calculated according to the following formula: Get the frequency representative value of starting the child lock function ,in It is the threshold of the number of times the child lock function is activated within the set time period in the database. When the smart door lock activates the child lock, the function is double locking. When the child lock is activated, the smart door lock functions as a single lock. When the first detection unit of the smart door lock detects that there is no adult user in the room, the function of the smart door lock after activating the child lock is a double locking function.

7. A method for activating a child lock function based on a smart door lock according to claim 6, characterized in that: The single locking function of the smart door lock after the child lock is activated includes locking the palm print sensor on the door handle of the smart door lock, so that the door opening user cannot open the door through the door handle of the smart door lock. At this time, the adult user opens the door through the face recognition method on the smart door lock; The double locking function of the smart door lock after the child lock is activated includes locking all door opening methods of the smart door lock. The door can only be opened after an adult user performs the corresponding unlocking operation on the smart door lock.

8. A method for activating a child lock function based on a smart door lock according to claim 7, characterized in that: The smart door lock early warning prompt includes a first early warning prompt and a second early warning prompt; The first warning prompt includes giving a voice warning prompt to the indoor underage user who intends to approach the smart door lock until the indoor underage user moves away from the smart door lock; The second warning prompt includes a voice prompt to the indoor underage user who intends to approach the smart door lock, and a mobile phone terminal warning prompt to the adult user, until the indoor underage user moves away from the smart door lock or the adult user controls the smart door lock to perform corresponding operations.

9. A method for activating a child lock function based on a smart door lock according to claim 8, characterized in that: The third detection unit detects whether the indoor underage user is close to the smart door lock and determines whether an early warning prompt is required. The specific detection and judgment process is as follows: The straight-line distance between the indoor underage user and the smart door lock detected by the third detection unit is recorded as , set according to the calculation formula Get the door opening intention value of the indoor underage user ,in and They are respectively represented as the upper threshold of the straight-line distance between an indoor underage user and the smart door lock in the database and the lower threshold of the straight-line distance between an indoor underage user and the smart door lock; like , then the indoor underage user detected by the third detection unit is not close to the smart door lock; if , then the third detection unit detects that the indoor underage user has the intention to approach the smart door lock; if , then the third detection unit detects that the indoor underage user has approached the smart door lock; When the third detection unit detects that the indoor underage user is not close to the smart door lock, it is determined that the smart door lock does not issue an early warning prompt; When the third detection unit detects that the indoor underage user has the intention to approach the smart door lock, it is determined that the smart door lock issues a first warning prompt to the user who opens the door; When the third detection unit detects that an indoor underage user has approached the smart door lock, it is determined that the smart door lock issues a first warning prompt to the indoor underage user and a second warning prompt to the adult user at the same time.

10. A smart door lock, used to execute a method for activating a child lock function based on a smart door lock as described in claims 1-9, characterized in that: include: First detection unit: The first detection unit on the smart door lock detects the total number of adult users in the room, and then determines whether there are adult users in the room; Second detection unit: When an adult user is present in the room and the user turns the door handle connected to the smart door lock to open the door, the second detection unit on the door handle of the smart door lock obtains the pressure value and palm print information value of the user acting on the door handle, and then analyzes and obtains the door opening evaluation coefficient of the user to determine whether the child lock function needs to be activated; The third detection unit: When there is no adult user in the room, the smart door lock activates the child lock function. At the same time, the third detection unit detects whether a minor user in the room is close to the smart door lock, and determines whether an early warning prompt is needed.
