Description

Technical Field

[0001] The present invention relates to the technical field of smart door locks, and in particular to a control method, system and device for a smart door lock. Background Art

[0002] Magnetic smart door locks are widely used in scenarios such as community entrances and exits and company entrances and exits. Since the application scenarios of magnetic smart door locks generally have the characteristics of large traffic flow, magnetic smart door locks are easily damaged during the opening and closing process, resulting in the magnetic smart door locks being unable to close. Therefore, before the magnetic smart door locks are repaired, everyone can enter various application scenarios through the magnetic smart door locks, reducing the security of various application scenarios. Therefore, it is very necessary to detect the problem of magnetic smart door locks being unable to close and perform certain control adjustments.

[0003] Prior art, such as the invention patent application with announcement number: CN118262439A, discloses a smart lock control method and system based on the Internet of Things, the method includes: determining the information of late children, including the child's student number and the child's name, determining the corresponding guardian information, the guardian information includes the guardian's facial image; sending the late child information and guardian information to the smart lock for storage; collecting facial images through the external camera to control the smart lock to unlock; when the current time reaches the late time threshold, sending the latest late child information and guardian information to the class teacher account; the expected arrival information includes several arrival times; generating early warning information based on the arrival time and the guardian's pick-up situation. In this way, even if a parent cannot pick up the child on time from school, the class teacher can also get off work on time.

[0004] Prior art, such as the invention patent application with announcement number: CN118072426A, discloses a hash-based smart door lock user information storage method, unlocking method and smart door lock, the method comprising: setting an AES128 encryption key in the smart door lock; the user sets a first password, and the first password is converted into a first ciphertext of 128 bytes through the AES128 algorithm; the first ciphertext generates a first key-value value through a hash function; and the first key-value value is stored in the storage unit of the smart door lock.

[0005] It can be seen from the above scheme that the current control method of the smart door lock lacks certain attention to the relevant adjustment according to the problem that the magnetic smart door lock cannot be closed due to various conditions of the body. During the use of the magnetic smart door lock, due to the power supply abnormality, switch abnormality and electromagnet offset problems, it is easy for the two electromagnets of the magnetic smart door lock to fail to adsorb each other normally, resulting in the magnetic smart door lock being in an open state for a long time, and the switch problem is often difficult to detect, and the person in charge of the smart door lock often does not check the magnetic smart door lock in real time. If there is a problem with the magnetic smart door lock, no certain compensation adjustment and emergency notification are performed, the safety of the protection area of ​​the magnetic smart door lock is reduced. At the same time, in addition to its own reasons, the magnetic smart door lock may also be unable to close due to human reasons. In actual use, some users sometimes hang objects, such as branches, between the movable door and the fixed door frame of the smart door lock for convenience, causing the door shaft to encounter obstacles when rotating back and unable to continue to rotate normally, thus unable to close, reducing the safety of the protection area of ​​the magnetic smart door lock.

If so, notify the person in charge of the smart door lock to inspect the push-to-open switch. If not, remove the door shaft obstruction of the magnetic smart door lock. If the magnetic smart door lock is still in a state where the electromagnet cannot be closed, notify the person in charge of the smart door lock to inspect the entire magnetic smart door lock.

[0011] The second aspect of the present invention provides a control system for a control method of a smart door lock, including: a smart door lock abnormality detection module, used to determine whether the magnetic smart door lock is in a state where the electromagnet cannot be closed, and if so, execute a power failure control module.

If not, the debris blocking control module is executed. If so, the electromagnet increases the magnetic force and notifies the person in charge of the smart door lock to correct the electromagnet. If the magnetic smart door lock is still in a state where the electromagnet cannot be closed, the debris blocking control module is executed.

[0014] The debris blocking control module is used to determine whether there is an abnormality in the push-to-open door switch of the magnetic smart door lock. If so, the person in charge of the smart door lock will be notified to inspect the push-to-open door switch. If not, the door shaft obstruction of the magnetic smart door lock will be removed. If the magnetic smart door lock is still in a state where the electromagnet cannot be closed, the person in charge of the smart door lock will be notified to inspect the entire magnetic smart door lock.

[0015] A third aspect of the present invention provides a smart door lock device, which stores one or more programs, and the one or more programs can be executed by one or more processors to implement the steps in a smart door lock control method as described in the present invention.

This can alleviate the problem of the magnetic smart door lock failing to close to a certain extent, thereby ensuring the safety of the protection area of ​​the magnetic smart door lock.

[0018] (3) Step 4 of the present invention is to control the debris blocking.

When an object is suspended between the movable door and the fixed door frame of the smart door lock, causing the door shaft to be unable to rotate normally, the movable door of the magnetic smart door lock is moved in the direction of opening the door, so that the object suspended between the movable door and the fixed door frame of the smart door lock falls off, ensuring that the door shaft can rotate normally.

[0025] The opening time threshold is obtained from the local database, and the opening time of the door magnetic sensor of the magnetic smart door lock is compared with the opening time threshold. If the opening time of the door magnetic sensor of the magnetic smart door lock is greater than the opening time threshold, it is determined that the magnetic smart door lock is in a state where the electromagnet cannot be closed.

[0029] Step 1 of the present invention is to detect abnormalities in the smart door lock, by preliminarily detecting whether the magnetic smart door lock cannot be closed, so as to facilitate subsequent regulation.

[0030] Step 2. Power failure control: Determine whether there is a power input problem for the electromagnets of the magnetic smart door lock. If not, proceed to step 3. If yes, adjust the power input and notify the person in charge of the smart door lock to check the power supply line. If the magnetic smart door lock is still in a state where the electromagnet cannot be closed, proceed to step 3.

[0031] It should be noted that each electromagnet only includes two electromagnets, one is fixed at the closed position of the smart door lock, and the other is installed on the movable door of the smart door lock.

[0032] It should also be noted that power input problems include: power outages and problems with insufficient magnetic force due to low current.

[0033] In a specific embodiment of the present invention, the specific judgment method for judging whether there is a power input problem for each electromagnet belonging to the magnetic smart door lock is: obtaining the input voltage value and input current value of each electromagnet belonging to the magnetic smart door lock.

[0034] The lower limit input voltage value is obtained from the local database. If the input voltage value of a certain electromagnet belonging to the magnetic smart door lock is less than the lower limit input voltage value, it is determined that the electromagnet belonging to the magnetic smart door lock has a power outage problem.

[0035] The appropriate input current value is obtained from the local database. If the input current value of a certain electromagnet belonging to the magnetic smart door lock is less than the appropriate input current value, it is determined that the electromagnet belonging to the magnetic smart door lock has a problem of insufficient magnetic force due to too low current.

[0036] In a specific embodiment, the input voltage value and input current value of each electromagnet belonging to the magnetic smart door lock are obtained by: obtaining the input voltage value of each electromagnet belonging to the magnetic smart door lock from a voltage sensor, and obtaining the input current value of each electromagnet belonging to the magnetic smart door lock from a current sensor.

[0037] In a specific embodiment of the present invention, the power input adjustment is performed, and the specific adjustment method is: if a power outage occurs in a certain electromagnet belonging to the magnetic smart door lock, the current input circuit of the electromagnet belonging to the magnetic smart door lock is switched from the main circuit to the backup circuit, and the electromagnet belonging to the magnetic smart door lock is powered by the second power supply.

[0038] If a certain electromagnet belonging to the magnetic smart door lock has a problem of insufficient magnetic force due to low current, open the parallel circuit of the electromagnet belonging to the magnetic smart door lock, obtain the appropriate input current value i of the electromagnet from the local database, and calculate the resistance setting value of the sliding rheostat on the parallel circuit of the electromagnet belonging to the magnetic smart door lock according to the input voltage value a and input current value b of the electromagnet belonging to the magnetic smart door lock. , and accordingly set the resistance value of the sliding rheostat on the parallel circuit of the electromagnet belonging to the magnetic smart door lock.

[0039] Step 3. Magnetic iron plate offset control: Determine whether the electromagnets belonging to the magnetic smart door lock are in an offset state. If not, execute step 4. If yes, increase the magnetic force of the electromagnet and notify the person in charge of the smart door lock to correct the electromagnet. If the magnetic smart door lock is still in a state where the electromagnet cannot be closed, execute step 4.

[0040] In a specific embodiment of the present invention, the specific method for determining whether each electromagnet belonging to the magnetic smart door lock is in an offset state is as follows: obtaining the height value of each characteristic point of each electromagnet belonging to the magnetic smart door lock from the ground , where x represents the number of each electromagnet, , n represents the number of each feature point, , m is a positive integer greater than 2.

[0041] Get the initial ground height value of each feature point of each electromagnet belonging to the magnetic smart door lock from the local database , the height offset coefficient of each electromagnet of the magnetic smart door lock from the ground .

[0042] The height offset coefficient threshold from the ground is obtained from the local database. If the height offset coefficient from the ground of a certain electromagnet belonging to the magnetic smart door lock is greater than the height offset coefficient threshold from the ground, it is determined that the electromagnet belonging to the magnetic smart door lock is in an offset state, thereby determining whether each electromagnet belonging to the magnetic smart door lock is in an offset state.

[0043] In a specific embodiment, the height value of each characteristic point of each electromagnet belonging to the magnetic smart door lock is obtained by a specific method: the height value of each characteristic point of each electromagnet belonging to the magnetic smart door lock is obtained by a microwave sensor installed at each characteristic point of each electromagnet belonging to the magnetic smart door lock.

[0044] In a specific embodiment of the present invention, the electromagnet increases the magnetic force operation, and the specific operation method is: randomly select an electromagnet belonging to the magnetic smart door lock as the target electromagnet, obtain the distance value between each feature point of the target electromagnet belonging to the magnetic smart door lock and the feature point corresponding to another electromagnet .

[0045] Get the reference distance value of each feature point of the target electromagnet of the magnetic smart door lock and the feature point corresponding to another electromagnet from the local database , calculate the distance increase hazard coefficient of the target electromagnet of the magnetic smart door lock .

[0046] Obtain the target input current value corresponding to each distance increase hazard coefficient interval from the local database, map the target input current value j of the target electromagnet belonging to the magnetic smart door lock, obtain the input voltage value k and input current value r of the target electromagnet belonging to the magnetic smart door lock when performing the electromagnet increase magnetic force operation, open the parallel circuit of the target electromagnet belonging to the magnetic smart door lock, and calculate the resistance setting value of the sliding rheostat on the parallel circuit of the target electromagnet belonging to the magnetic smart door lock , and accordingly set the resistance value of the sliding rheostat on the parallel circuit of the target electromagnet belonging to the magnetic smart door lock.

[0047] In a specific embodiment, the distance values ​​of each characteristic point of the target electromagnet belonging to the magnetic smart door lock and the characteristic points corresponding to another electromagnet are obtained by a microwave sensor installed at each characteristic point of the target electromagnet belonging to the magnetic smart door lock to obtain the distance values ​​of each characteristic point of the target electromagnet belonging to the magnetic smart door lock and the characteristic points corresponding to another electromagnet.

[0048] It should be noted that the microwave sensors installed at the characteristic points of the two electromagnets are paired one by one, so as to achieve a result that the characteristic points of the two electromagnets are paired one by one.

[0049] In a specific embodiment, the input voltage value and input current value of the target electromagnet belonging to the magnetic smart door lock when performing the electromagnet increasing magnetic force operation are obtained, and the specific acquisition method is: the input voltage value of the target electromagnet belonging to the magnetic smart door lock when performing the electromagnet increasing magnetic force operation is obtained from the voltage sensor, and the input current value of the target electromagnet belonging to the magnetic smart door lock when performing the electromagnet increasing magnetic force operation is obtained from the current sensor.

[0050] Step 2. power failure regulation and step 3. magnetic iron plate offset regulation of the present invention, when the magnetic smart door lock cannot close, sequentially detect whether a power failure or an electromagnet offset problem occurs, thereby activating a backup power supply or activating a sliding rheostat on a parallel line to adjust the current, increase the mutual attraction between the electromagnets belonging to the magnetic smart door lock, and alleviate the problem that the magnetic smart door lock cannot close to a certain extent, thereby ensuring the safety of the protection area of ​​the magnetic smart door lock.

[0051] Step 4. Debris blocking control: Determine whether there is any abnormality in the push-to-open switch of the magnetic smart door lock. If so, notify the person in charge of the smart door lock to inspect the push-to-open switch. If not, remove the door shaft obstruction of the magnetic smart door lock. If the magnetic smart door lock is still in a state where the electromagnet cannot be closed, notify the person in charge of the smart door lock to inspect the entire magnetic smart door lock.

[0052] In a specific embodiment of the present invention, the specific method for determining whether the push-to-open switch of the magnetic smart door lock is abnormal is as follows: obtaining the capacitance value of the charging capacitor of the detection switch of the magnetic smart door lock.

[0053] The capacitance value threshold is obtained from the local database. If the capacitance value of the charging capacitor of the detection switch belonging to the magnetic smart door lock is greater than the capacitance value threshold, it is determined whether the push-to-open switch belonging to the magnetic smart door lock is abnormal.

[0054] The detection switch charging capacitor is used to slowly charge the detection switch charging capacitor when the push-to-open switch of the magnetic smart door lock is in the door-opening state.

[0055] In a specific embodiment, the capacitance value of the charging capacitor of the detection switch belonging to the magnetic smart door lock is obtained by a specific method: the capacitance value of the charging capacitor of the detection switch belonging to the magnetic smart door lock is obtained by a capacitance sensor.

[0056] In a specific embodiment of the present invention, the specific judgment method for performing the door shaft obstruction removal operation is as follows: obtaining the input current setting value and current input duration corresponding to each distance increase hazard coefficient interval from the local database, and mapping the input current setting value and current input duration of the target electromagnet belonging to the magnetic smart door lock according to the distance increase hazard coefficient of the target electromagnet belonging to the magnetic smart door lock, and based on the method for calculating the resistance setting value of the sliding rheostat on the parallel circuit of the target electromagnet belonging to the magnetic smart door lock, similarly calculate the resistance setting value of the sliding rheostat on the parallel circuit of the target electromagnet belonging to the magnetic smart door lock when performing the door shaft obstruction removal operation, and mark it as the target resistance setting value of the target electromagnet belonging to the magnetic smart door lock.

[0057] Change the current input direction of the target electromagnet of the magnetic smart door lock to the opposite direction, so that the magnetic force generated by the electromagnet of the magnetic smart door lock is changed from the original attraction to repulsion, and set the resistance setting value of the sliding rheostat on the parallel circuit of the target electromagnet of the magnetic smart door lock to the target resistance setting value, and continue to input current until the current input time of the target electromagnet of the magnetic smart door lock is reached, and adjust the current input direction of the target electromagnet of the magnetic smart door lock to the original direction.

[0058] Step 4 of the present invention is to control the obstruction of debris. By simply setting a charging capacitor and a capacitance sensor at the position of the push-to-open switch of the magnetic smart door lock, it is possible to promptly determine whether there is an abnormality in the push-to-open switch of the magnetic smart door lock, and design a reverse circuit in the electromagnet of the magnetic smart door lock to ensure that the input current direction of the electromagnet of the magnetic smart door lock can be adjusted. When an object is suspended between the movable door and the fixed door frame of the smart door lock, causing the door shaft to be unable to rotate normally, the movable door of the magnetic smart door lock is moved in the direction of opening the door, so that the object suspended between the movable door and the fixed door frame of the smart door lock falls off, ensuring that the door shaft can rotate normally.
