Description

Technical Field

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

[0002] Smart door locks are usually in a low-power dormant state for a long time, and the battery level of the smart door lock can only be updated when the user wakes up and opens the door. In particular, when the battery level is less than 20%, the door lock will be prompted to indicate low battery when it is used again, but the user cannot obtain accurate information on how long it can continue to be used, which can easily cause users to have battery anxiety.

[0003] In the related art, in order to avoid power anxiety, the smart door lock is generally woken up regularly every day through software to update the power information, or the power is monitored in real time. However, waking up and updating the power information every day and monitoring the power in real time will cause additional power consumption. Summary of the invention

[0004] In view of this, the present invention provides a control method of a smart door lock and a smart door lock to solve the problem that daily waking up to update power information and real-time power monitoring will cause additional power consumption.

[0005] In a first aspect, the present invention provides a control method for an intelligent door lock, comprising:

[0006] Get the door opening information of the smart door lock;

[0007] Obtaining the remaining power of the battery of the smart door lock, and predicting a first time period when the remaining power is consumed to a first preset power according to a power consumption model preset in the smart door lock;

[0008] If the door opening information is not obtained within the first time period, after the first time period ends, the smart door lock is controlled to turn on the super power saving mode;

[0009] If the door opening information is obtained within the first time period, the remaining power is updated and the first time period is re-predicted.

[0010] Beneficial effect: By predicting the first time period, when the user does not use the smart door lock for a long time due to reasons such as long-term absences, and the battery cannot be replaced in time, the smart door lock can be controlled to automatically turn on the super power saving mode according to the predicted first time period to extend the battery life; and when the door opening information is obtained, the remaining power is updated and the first time period is re-predicted to prevent the power consumed each time the door is opened from affecting the originally predicted first time period, thereby ensuring the correctness of the first time period and ensuring the timely activation of the super power saving mode.

[0011] In an optional implementation, the obtaining the remaining power of the battery of the smart door lock further includes:

[0012] Predicting, according to a power consumption model preset in the smart door lock, a second time period when the remaining power is consumed to a second preset power;

[0013] If the door opening information is not obtained within the second time period, the smart door lock is automatically awakened after the second time period ends, the remaining power is re-updated, the first time period is re-predicted, and a low voltage alarm is sent to the client;

[0014] If the door opening information is obtained within the second time period, the remaining power is updated, and the first time period and the second time period are re-predicted;

[0015] Wherein, the first preset power is less than the second preset power.

[0016] Beneficial effect: the first preset power is less than the second preset power. Through the prediction of the second time period, when the user does not use the smart door lock due to long-term absences and other reasons, and cannot replace the battery in time, a low voltage alarm is sent to the client to warn the user that the battery is about to run out, and the first time period is re-predicted to obtain a more accurate first time period, so that the smart door lock can automatically turn on the super power saving mode in time and accurately; and when the door opening information is obtained, the remaining power is updated and the first time period and the second time period are re-predicted to prevent the power consumed each time the door is opened from affecting the originally predicted first time period and second time period, thereby ensuring the correctness of the first time period and the second time period, ensuring that the smart door lock can send a low voltage alarm to the client in time, and ensuring the timely activation of the super power saving mode.

[0017] In an optional implementation, controlling the smart door lock to start the super power saving mode includes: controlling the smart door lock to retain the function of the first static power consumption unit and turning off the function of the second static power consumption unit.

[0018] Beneficial effect: The power consumption of smart door locks consists of dynamic power consumption and static power consumption. The power consumption of the smart door lock during the door opening process is mainly related to the dynamic power consumption, and the power consumption of the smart door lock when in standby mode is mainly related to the static power consumption. Therefore, when the user does not use the smart door lock for a long time due to reasons such as long-term outings and enters the super power saving mode, controlling the smart door lock to turn off the function of the second static power consumption unit can reduce the overall static power consumption and extend the battery life.

[0019] In an optional implementation, after the smart door lock in the super power saving mode is awakened by the first static power consumption unit, the second static power consumption unit is turned on after the smart door lock enters a dynamic power consumption state.

[0020] Beneficial effect: The second static power consumption unit is turned on after the smart door lock is awakened, which can ensure that the user can fully use the functions of the smart door lock to facilitate the user to open the door.

[0021] In an optional embodiment, after the smart door lock in the super power saving mode is awakened by the first static power consumption unit, if no operation information about the smart door lock is obtained within a preset timeout period, the smart door lock is controlled to turn on the super power saving mode again.

[0022] Beneficial effect: If no operation information about the smart door lock is obtained within the preset timeout period, the smart door lock is controlled to turn on the super power saving mode again to prevent the second static power consumption unit from continuing to waste battery power, thereby extending the battery life.

[0023] In an optional implementation, the first static power consumption unit is a fingerprint unit and an MCU unit, and the second static power consumption unit includes any one or more of a cat's eye unit, a touch unit, a Bluetooth broadcast unit, and a radar sensing unit.

[0024] In an optional implementation, the first preset power level is 10% of the total power of the battery.

[0025] In an optional implementation, the second preset power level is 20% of the total power of the battery.

[0026] In an optional implementation, after replacing the battery of the smart door lock, the remaining power of the battery is obtained, and if the remaining power is greater than the first preset power, the smart door lock is controlled to automatically exit the super power saving mode.

[0027] Beneficial effect: After replacing the door lock, it will automatically exit the super power saving mode, which can ensure that the user has a better experience when using the door lock.

[0028] In an optional embodiment, the control method of the smart door lock also includes: controlling the smart door lock to enter a power saving mode through an application on the client, and the power saving mode includes controlling the opening or closing of any one or more of the fingerprint unit, cat's eye unit, touch unit, Bluetooth broadcast unit and radar sensing unit through the application.

[0029] Beneficial effect: When the user does not use the smart door lock for a long time due to reasons such as long-term absence, or the user does not want to use some functions of the smart door lock, the client application can control the opening or closing of any one or more of the fingerprint unit, cat's eye unit, touch unit, Bluetooth broadcast unit and radar sensing unit to enter the power saving mode.

[0030] In a second aspect, the present invention also provides a smart door lock for executing the above-mentioned smart door lock control method. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0037] Combine the following Figures 1 to 4 , describing an embodiment of the present invention.

[0038] According to an embodiment of the present invention, on the one hand, a control method of a smart door lock is provided, comprising:

[0039] S101, obtaining door opening information of the smart door lock;

[0040] S102, obtaining the remaining power of the battery of the smart door lock, and predicting a first time period when the remaining power is consumed to a first preset power according to a power consumption model preset in the smart door lock;

[0041] S103: If the door opening information is not obtained within the first time period, after the first time period ends, control the smart door lock to turn on the super power saving mode;

[0042] S104: If the door opening information is obtained within the first time period, the remaining power is updated and the first time period is re-predicted.

[0043] By predicting the first time period, when the user does not use the smart door lock for a long time due to reasons such as long-term absences, and cannot replace the battery in time, the smart door lock can be controlled to automatically turn on the super power saving mode according to the predicted first time period to extend the battery life; and when the door opening information is obtained, the remaining power is updated and the first time period is re-predicted to prevent the power consumed each time the door is opened from affecting the originally predicted first time period, thereby ensuring the correctness of the first time period and ensuring the timely activation of the super power saving mode.

[0044] In one embodiment, obtaining the remaining power of the battery of the smart door lock further includes:

[0045] S201, predicting a second time period when the remaining power is consumed to a second preset power according to a power consumption model preset in the smart door lock;

[0046] S202: If the door opening information is not obtained within the second time period, then after the second time period ends, the smart door lock is automatically awakened, the remaining power is re-updated, the first time period is re-predicted, and a low voltage alarm is sent to the client;

[0047] S203: if the door opening information is obtained within the second time period, updating the remaining power, and re-predicting the first time period and the second time period;

[0048] Wherein, the first preset power is less than the second preset power.

[0049] The first preset power is less than the second preset power. Through the prediction of the second time period, when the user does not use the smart door lock due to long-term absences and other reasons, and cannot replace the battery in time, a low voltage alarm is sent to the client to warn the user that the battery is about to run out, and the first time period is re-predicted to obtain a more accurate first time period, so that the smart door lock can automatically turn on the super power saving mode in time and accurately; and when the door opening information is obtained, the remaining power is updated and the first time period and the second time period are re-predicted to prevent the power consumed each time the door is opened from affecting the originally predicted first time period and second time period, thereby ensuring the correctness of the first time period and the second time period, ensuring that the smart door lock can send a low voltage alarm to the client in time, and ensuring the timely activation of the super power saving mode.

[0050] In one embodiment, controlling the smart door lock to start the super power saving mode includes: controlling the smart door lock to retain the function of the first static power consumption unit and turning off the function of the second static power consumption unit.

[0051] The power consumption of smart door locks consists of dynamic power consumption and static power consumption. The power consumption of smart door locks during the door opening process is mainly related to dynamic power consumption, and the power consumption of smart door locks in standby mode is mainly related to static power consumption. Therefore, when the user does not use the smart door lock for a long time due to reasons such as long-term outings and enters the super power saving mode, controlling the smart door lock to turn off the function of the second static power consumption unit can reduce the overall static power consumption and extend the battery life.

[0052] Dynamic power consumption is mainly the power consumption generated when using a smart door lock to open the door. Dynamic power consumption units usually include biometric units, sound prompt units, light display units, and motor units. The characteristics of dynamic power consumption are generally large power consumption but short duration. The effective door opening life of a smart door lock is mainly related to dynamic power consumption, that is, the higher the frequency of door opening per day, the more dynamic power consumption is consumed and the shorter the total life.

[0053] Static power consumption mainly refers to the power consumption when the smart door lock is in sleep standby state. The main units of static power consumption include fingerprint unit, MCU unit, cat's eye unit, touch unit, Bluetooth broadcast unit and radar sensing unit. The static power consumption is generally small, but it is consumed continuously for 24 hours. The total standby time of the smart door lock is mainly related to the static power consumption, that is, under the same frequency of door opening, the higher the static power consumption, the shorter the total battery life.

[0054] Specifically, the cat's eye unit is a static power consumption unit in which the user wakes up the smart door lock remotely through WIFI to view the cat's eye video; the touch unit is a static power consumption unit in which the user touches the panel to wake up the smart door lock and enters the password; the Bluetooth broadcast unit is a static power consumption unit in which the user wakes up the smart door lock through a mobile terminal such as a mobile phone and opens the door through a mobile terminal such as a mobile phone; the radar sensing unit is a static power consumption unit in which the user wakes up the smart door lock through human body proximity sensing to perform face recognition; the fingerprint unit is a static power consumption unit in which the user touches the fingerprint head to wake up the smart door lock to perform fingerprint recognition; the MCU unit is a microcontroller unit, a static power consumption unit with a fixed low power consumption current.

[0055] Specifically, in this embodiment, the power consumption model (battery life model) is:

[0056] D=C / (I 动 *T 动 *N+I 静 *T 静 ).

[0057] Among them, D is the total battery life (days); C is the total battery power (mah); N is the number of door openings per day (times); I is the current in different scenarios (mA); T is the current duration in different scenarios (h).

[0058] Assuming the total battery capacity is 5000mah, the dynamic power consumption is 400ma, each lasting 10 seconds, and the door is opened 10 times a day; the static power consumption is 0.5ma, and the consumption is continuous; the total battery life is:

[0059]

[0060] From the above power consumption model, it can be seen that when the user's usage habits are determined, that is, the frequency of opening the door is fixed, the total battery life of the smart door lock is inversely proportional to the static power consumption. The lower the static power consumption, the longer the total battery life. Static power consumption is generally related to the overall design architecture of the door lock. From a technical perspective, each user-perceivable function item corresponds to each current that needs to be consumed, that is, the function is linked to power consumption. Therefore, when the user does not use the smart door lock for a long time due to reasons such as long-term outings and enters the super power saving mode, controlling the smart door lock to turn off the function of the second static power consumption unit can reduce the overall static power consumption and extend the battery life.

[0061] In one embodiment, after the smart door lock in the super power saving mode is awakened by the first static power consumption unit, the second static power consumption unit is turned on after the smart door lock enters the dynamic power consumption state.

[0062] The second static power consumption unit is turned on after the smart door lock is awakened, which can ensure that the user can fully use the functions of the smart door lock to facilitate the user to open the door.

[0063] In one embodiment, after the smart door lock in the super power saving mode is awakened by the first static power consumption unit, if no operation information about the smart door lock is obtained within a preset timeout period, the smart door lock is controlled to turn on the super power saving mode again.

[0064] If the operation information about the smart door lock is not obtained within the preset timeout period, the smart door lock is controlled to turn on the super power saving mode again to prevent the second static power consumption unit from continuing to waste battery power, thereby extending the battery life.

[0065] In one embodiment, the first static power consumption unit is a fingerprint unit and an MCU unit, and the second static power consumption unit includes any one or more of a cat's eye unit, a touch unit, a Bluetooth broadcast unit, and a radar sensing unit.

[0066] The first static power consumption unit is the fingerprint unit and the MCU unit. The MCU unit needs to be kept open to ensure the basic operation of the smart door lock. The fingerprint unit can ensure that the smart door lock can be awakened. Since the fingerprint unit and the MCU unit only account for 10% of the overall static power consumption, keeping the fingerprint unit and the MCU unit open can not only meet the basic wake-up function of the smart door lock, but also reduce static power consumption and extend the battery life by about 10 times. Referring to the aforementioned power consumption model and assumed data, when the user does not use the smart door lock for a long time and turns on the super power saving mode, the battery life is calculated as follows:

[0067] D = (5000mah*10%) / (0.5ma*10%*24) = 416 days.

[0068] Among them, the battery life of 416 days after turning off the second static power consumption unit is much longer than the battery life under normal use.

[0069] In one embodiment, the first preset power is 10% of the total power of the battery.

[0070] In one embodiment, the second preset power is 20% of the total power of the battery.

[0071] In one embodiment, after replacing the battery of the smart door lock, the remaining power of the battery is obtained, and if the remaining power is greater than the first preset power, the smart door lock is controlled to automatically exit the super power saving mode.

[0072] After replacing the door lock, it will automatically exit the super power saving mode, ensuring that the user has a better user experience when using the door lock.

[0073] In one embodiment, the control method of the smart door lock also includes: controlling the smart door lock to enter a power saving mode through an application on the client, and the power saving mode includes controlling the opening or closing of any one or more of a fingerprint unit, a cat's eye unit, a touch unit, a Bluetooth broadcast unit, and a radar sensing unit through the application.

[0074] When the user does not use the smart door lock for a long time due to reasons such as long-term absence, or the user does not want to use some functions of the smart door lock, the user can control the opening or closing of any one or more of the fingerprint unit, cat's eye unit, touch unit, Bluetooth broadcast unit and radar sensing unit through the client application to enter the power saving mode.

[0075] According to an embodiment of the present invention, on the other hand, a smart door lock is provided for executing the above-mentioned smart door lock control method.

[0076] Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the appended claims.
