[0109] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0110] For the normal use and performance of smart security equipment (such as smart door locks), it is crucial to provide them with continuous and stable power support. In related technologies, using energy to wirelessly charge smart security equipment is an effective method. Using wireless charging devices, long-distance, high-power wireless charging can be achieved, providing sufficient energy for smart security equipment. However, it should be noted that the energy transmission power during wireless charging is relatively high, so high-power energy transmission may pose a safety risk during the charging process.

[0111] To this end, in response to the above-mentioned problems of the prior art, the present disclosure proposes a wireless charging method, which detects the power level of the battery in the intelligent security equipment and sends a charging start instruction to the wireless charging device; determines whether the wireless charging device sends an energy shutdown notification; if the wireless charging device does not send an energy shutdown notification, performs a safety detection task, and sends a charging shutdown instruction to the wireless charging device based on the detection result corresponding to the safety detection task, so that the wireless charging device stops transmitting energy, thereby realizing safety detection during the wireless charging process of the intelligent security equipment. At the same time, when the human body sensing sensor detects that a human body is approaching, it will immediately stop transmitting energy to ensure that the energy will not be irradiated on the human body, avoiding harm to the human body, thereby increasing the protection strategy of wireless charging and improving the safety of the wireless charging process.

[0112] Figure 1 is a flow chart of a wireless charging protection method provided by an embodiment of the present disclosure. As shown in Figure 1, the method is applied to smart security equipment, specifically smart door locks, smart cameras, smart alarm systems, and other smart security equipment that can implement wireless charging. In this disclosure, a smart door lock is used as an example. The method includes the following steps:

[0113] Step 101: Detect the power level of the battery in the intelligent security device and send a charging start instruction to the wireless charging device.

[0114] In one implementation of the present disclosure, the smart security device can determine the power level of the battery in the smart security device based on the smart door lock control unit in the smart security device, and determine whether to send a charging start instruction to the wireless charging device based on the determined current battery power level.

[0115] The charging start command instructs the wireless charging device to transmit energy. The wireless charging device includes a receiver and a transmitter. The charging start command specifically instructs the transmitter to transmit energy to provide energy to the receiver. The receiver receives the energy transmitted by the transmitter and converts it into electrical energy. The receiver can be connected to the battery of a smart security device to charge the battery.

[0116] Step 102: Determine whether the wireless charging device sends an energy shutdown notification.

[0117] In one embodiment of the present disclosure, since the energy transmission control unit of the transmitting end in the wireless charging device and the smart door lock control unit in the smart security device both include wireless communication units, the smart door lock control unit can be communicatively connected with the energy transmission control unit to realize communication interaction between the smart security device and the wireless charging device.

[0118] Therefore, the smart door lock control unit in the smart security device can be used to determine whether the energy transmission control unit of the transmitting end of the wireless charging device sends an energy shutdown notification.

[0119] In step 103 , if the wireless charging device does not send an energy shutoff notification, a safety detection task is executed, and according to a detection result corresponding to the safety detection task, a charging shutoff instruction is sent to the wireless charging device to stop the wireless charging device from transmitting energy.

[0120] In one embodiment of the present disclosure, if the energy emission control unit does not send an energy shutdown notification, the smart security device performs a safety detection task. Specifically, the safety detection task can be performed by the smart door lock control unit in the smart security device.

[0121] Among them, the security detection tasks may include detecting the switch status of the intelligent security equipment, determining whether the voltage signal and / or current signal is abnormal, and whether the battery is fully charged.

[0122] Therefore, according to the embodiments of the present disclosure, by detecting the power level of the battery in the smart security device, a charging start instruction is sent to the wireless charging device; it is determined whether the wireless charging device sends an energy shutdown notification; if the wireless charging device does not send an energy shutdown notification, a safety detection task is performed, and according to the detection result corresponding to the safety detection task, a charging shutdown instruction is sent to the wireless charging device to stop the wireless charging device from transmitting energy, thereby realizing safety detection during the wireless charging process of the smart security device. At the same time, when the human body sensing sensor detects that a human body is approaching, it will immediately stop transmitting energy to ensure that the energy will not be irradiated on the human body, avoiding harm to the human body, thereby increasing the protection strategy of wireless charging and improving the safety of the wireless charging process.

[0123] FIG2 is a flow chart of a wireless charging protection method provided by an embodiment of the present disclosure. FIG2 further defines step 101 based on the embodiment shown in FIG1. ​​In the embodiment shown in FIG2, step 101 includes step 201 and step 202. As shown in FIG2, the method includes the following steps:

[0124] Step 201: Determine the power level of the battery in the intelligent security device.

[0125] In some embodiments of the present disclosure, the current power value of the battery in the smart security device is determined by the smart door lock control unit in the smart security device.

[0126] Step 202: If the power level is less than or equal to the first preset power level, a charging instruction is sent to the wireless charging device.

[0127] In some embodiments of the present disclosure, if the current power value is less than or equal to the first preset threshold, it is determined that the current battery needs to be charged. At this time, the smart door lock control unit in the smart security device will send a charging instruction to the energy transmission control unit of the transmitting end in the wireless charging device.

[0128] Among them, the first preset power can be set according to actual conditions and is not limited in the embodiment of the present disclosure.

[0129] Step 203: Determine whether the wireless charging device sends an energy shutoff notification.

[0130] Step 203 has the same or similar function as the above-mentioned step 103, and its implementation can be performed with reference to the above-mentioned embodiment, which will not be described again here.

[0131] In step 204 , if the wireless charging device does not send an energy shutoff notification, a safety detection task is executed, and based on the detection result corresponding to the safety detection task, a charging shutoff instruction is sent to the wireless charging device to stop the wireless charging device from transmitting energy.

[0132] In some embodiments of the present disclosure, if the energy transmission control unit of the transmitting end in the wireless charging device does not send an energy shutdown notification, the smart door lock control unit of the smart security device performs a safety detection task and sends a charging shutdown instruction to the energy transmission control unit according to the detection result corresponding to the safety detection task.

[0133] Among them, the detection results corresponding to sending the charging shutdown instruction to the energy emission control unit are that the switch state of the current intelligent security device is on, the voltage signal or current signal received by the current intelligent security device is abnormal, and the current battery is fully charged.

[0134] Specifically, a schematic diagram of the wireless charging protection method on the intelligent security device side is shown in Figure 3. The wireless charging device disclosed herein can be a laser charging device or an electromagnetic charging device. Figure 3 takes the laser in the laser charging device as an example.

[0135] In an optional embodiment of the present disclosure, in response to a human-triggered on / off event of the smart security device, the on / off state of the smart security device is detected; if the smart security device is on, a charging shutdown instruction is sent to the wireless charging device. Specifically, when a human triggers a on / off event of the smart security device, i.e., someone opening the door from outside or inside, the smart door lock control unit in the smart security device immediately sends a charging shutdown instruction to the energy emission control unit of the laser charging device, instructing the energy emission control unit of the laser charging device to control the laser driver to turn off the laser. This ensures that the laser is off before the door is opened, either from outside or inside, thus protecting the user.

[0136] In an optional embodiment of the present disclosure, a voltage signal and / or current signal sent by a wireless charging device is received; it is determined whether the voltage signal is within a preset voltage range and / or whether the current signal is within a preset current range; if the voltage signal is not within the preset voltage range or the current signal is not within the preset current range, a charging shutdown instruction is sent to the wireless charging device. Specifically, since the smart door lock control unit is respectively connected to the photovoltaic cell voltage and the charging unit at the receiving end of the laser charging device. The smart door lock control unit can receive the voltage signal and / or current signal output by the photovoltaic cell voltage and the charging unit in real time. During the laser charging process, once the smart door lock control unit detects that the current voltage signal or current signal is not within the preset voltage range or the preset current range, it determines that the current voltage signal or current signal is abnormal. At this time, the smart door lock control unit in the smart security device will immediately send a charging shutdown instruction to the energy emission control unit of the laser charging device to instruct the energy emission control unit to control the laser driver to drive the laser to turn off the laser.

[0137] In an optional embodiment of the present disclosure, it is determined whether the power level of the battery in the smart security device has reached a second preset power level, and the second preset power level is greater than the first preset power level; if the power level has reached the second preset power level, a charging shutdown instruction is sent to the wireless charging device. Specifically, when the smart door lock control unit detects that the power level of the battery has reached the second preset power level, it is determined that the current battery is fully charged. The smart door lock control unit in the smart security device will immediately send a charging shutdown instruction to the energy emission control unit of the laser charging device to instruct the energy emission control unit to control the laser driver to drive the laser to turn off the laser.

[0138] In summary, according to the embodiments of the present disclosure, wireless charging of smart security devices using energy eliminates the need for additional cables or connectors, making the charging process simpler and more convenient, significantly improving charging efficiency and shortening charging time. Furthermore, safety checks are performed during wireless charging, adding protection measures. When a person approaches or the battery is fully charged, energy transmission is immediately stopped, reducing power consumption and ensuring that energy does not reach the human body. This is particularly true when using laser charging, which can prevent damage to the human eye.

[0139] FIG4 is a flow chart of a wireless charging protection method provided by an embodiment of the present disclosure. FIG5 is a schematic diagram of a wireless charging protection method for a wireless charging device in the present disclosure, taking the laser in a laser charging device as an example. As shown in FIG4 , the method is applied to a wireless charging device, specifically to the transmitter in the wireless charging device. The method comprises the following steps:

[0140] Step 301: Receive a charging start instruction sent by a smart security device.

[0141] In some embodiments of the present disclosure, since the transmitter in the wireless charging device and the smart security device both include wireless communication units, the energy transmission control unit can receive the charging start instruction sent by the smart door lock control unit in the smart security device through the wireless communication unit.

[0142] The receiving end of the wireless charging device can be located on one side of the smart security device or integrated into the smart security device, and the transmitting end of the wireless charging device is located on a side away from the smart security device.

[0143] Step 302 , in response to the charging start instruction, transmit energy to charge the battery of the intelligent security device, and perform human body detection within the energy radiation area corresponding to the energy.

[0144] In some embodiments of the present disclosure, since the transmitting end of the wireless charging device also includes a power supply unit, a transmission driver (laser driver), and an energy transmitter (laser), the power supply unit can provide power to the energy transmission control unit, and the energy transmission control unit can control the laser driver to drive the laser to emit energy (laser light energy) according to the charging start instruction.

[0145] The wireless charging device's receiving end is connected to one side of the smart security device and includes an energy conversion unit (photovoltaic cell unit), a boost unit, and a charging unit. The energy conversion unit receives energy from the transmitting end and converts it into electrical energy. The boost unit raises the lower voltage output by the photovoltaic cell unit to the required higher voltage to provide sufficient energy for the charging unit. The charging unit is used to connect to the battery in the smart security device to power it.

[0146] In addition, the energy transmission control unit is connected to the human body sensing sensor to detect whether there is a human body approaching the transmitting end.

[0147] A human presence sensor is a device that detects whether a person is near the transmitter and, based on the detection result, sends a sensing signal to the energy transmission control unit of the laser transmitter. It typically utilizes different technologies, such as PIR (passive infrared), radar, ultrasound, or TOF (time of flight). These technologies have slightly different principles and applications, but all detect human presence by sending a signal and measuring its reflection or transmission time. When a person approaches the transmitter, the human presence sensor detects the change in signal, triggering the corresponding control logic.

[0148] Step 303: If a human body is detected, the energy emission is stopped and an energy shutoff notification is sent to the smart security device.

[0149] In some embodiments of the present disclosure, when a human body approaches, the human body sensing sensor will send a sensing signal to the energy emission control unit. The energy emission control unit will start the emission driver according to the sensing signal, control the energy transmitter, stop the energy transmitter from emitting energy, and send an energy shutdown notification to the smart door lock control unit in the smart security device.

[0150] Furthermore, in some embodiments of the present disclosure, if no human body is detected, it is determined whether the smart security device has sent a charge-off instruction. If the smart security device has sent a charge-off instruction, the energy emission control unit stops emitting energy in response to the charge-off instruction. Specifically, if the human body sensing sensor has not detected a human body, the energy emission control unit determines whether the smart door lock control unit of the smart security device has sent a charge-off instruction. If the smart door lock control unit has sent a charge-off instruction, the energy emission control unit controls the emission driver to drive the laser energy emitter to stop emitting energy in response to the charge-off instruction.

[0151] In summary, in the embodiments of the present disclosure, by utilizing the human body sensing sensor in the wireless charging device for real-time detection and communicating and interacting with the intelligent security equipment, a human body protection method is added during wireless charging. When the human body sensing sensor detects that a person is approaching, it can immediately stop emitting energy to ensure that the energy does not irradiate the human body, avoid causing harm to the human body, and improve the safety of the laser charging process.

[0176] According to an embodiment of the present disclosure, the present disclosure also provides an electronic device, a readable storage medium, and a computer program product.

[0179] In some optional embodiments of the present application, a wireless charging protection method is provided. FIG8 shows a process 800 of the wireless charging method provided according to an embodiment of the present application. The wireless charging method includes the following steps:

[0180] Step 801: Control the associated transmitter to perform a laser activation operation according to target wireless charging activation information.

[0181] In some embodiments, based on the target wireless charging start-up information, the execution entity of the wireless charging method (e.g., a wireless charging device) may control the associated transmitter to perform a laser start-up operation. The wireless charging device may include a transmitter and a receiver. The transmitter may be used to perform wireless charging operations. The transmitter may be provided with a light energy conversion component group. The receiver may be used to receive the laser emitted by the transmitter and convert the light energy of the laser into electrical energy. The receiver may be provided with a reflector group. The light energy conversion components included in the light energy conversion component group may correspond one-to-one to the reflectors included in the reflector group, and the number of light energy conversion components included in the light energy conversion component group may be the same as the number of reflectors included in the reflector group. As an example, the reflector group may include four reflectors. The light energy conversion component group may include four light energy conversion components. The four reflectors may be respectively arranged around the receiver. The four light energy conversion components may be respectively arranged around the transmitter. The receiver may also be used to charge a smart door lock. The target wireless charging start-up information may be information indicating that the receiver is being charged. The target wireless charging start information may include a charging start time. For example, the target wireless charging start information may be "Charge the receiver at 11:00." In practice, the execution entity may control the transmitter to turn on the laser at the charging start time included in the target wireless charging start information. Specifically, the laser driver included in the transmitter may drive the laser to emit laser light.

[0182] In some optional implementations of some embodiments, the execution subject may control the associated transmitter to perform a laser activation operation according to the target wireless charging activation information by executing the following steps:

[0183] The first step is to determine whether the remaining battery power of the associated smart door lock is less than or equal to a preset warning power threshold. The associated smart door lock may be a smart door lock electrically connected to the receiver. The preset warning power threshold may be a pre-set power threshold below which charging is initiated. For example, the preset warning power threshold may be 10%.

[0184] In the second step, in response to determining that the remaining power of the smart door lock is less than or equal to the preset warning power threshold, a power warning message is generated based on the remaining power. The power warning message may be information to remind the user to charge the battery. In practice, in response to determining that the remaining power of the smart door lock is less than or equal to the preset warning power threshold, the execution entity may fill the remaining power into the preset power warning message template to obtain the power warning message. The preset power warning message template may be "The remaining power of the smart door lock is XX, please charge in time." The horizontal line is used to fill in the remaining power.

[0185] The third step is to send the above-mentioned power warning information to the associated terminal device. The above-mentioned terminal device can be a smart phone. Here, there is no limitation on the specific connection method between the above-mentioned execution entity and the above-mentioned associated terminal device. As an example, the above-mentioned execution entity can be connected to the above-mentioned associated terminal device by wire. As another example, the above-mentioned execution entity can also have a wireless connection with the above-mentioned associated terminal device. It should be pointed out that the above-mentioned wireless connection method can include but is not limited to 3G / 4G connection, WiFi connection, Bluetooth connection, WiMAX connection, Zigbee connection, UWB (ultrawideband) connection, and other wireless connection methods currently known or to be developed in the future.

[0186] In step 4, in response to receiving the target wireless charging start information sent by the terminal device, the associated transmitter is controlled to perform a laser turn-on operation. In practice, in response to receiving the target wireless charging start information sent by the terminal device, the execution subject may control the transmitter to turn on the laser at the charging start time included in the target wireless charging start information.

[0187] In some optional implementations of some embodiments, the execution subject may control the associated transmitter to perform a laser activation operation according to the target wireless charging activation information by executing the following steps:

[0188] The first step is to perform real-time charging current detection on the associated receiver to obtain real-time charging current information. The receiver may include a photovoltaic cell, a voltage regulator chip, and a lithium battery cell. The photovoltaic cell may be a solar cell. The voltage regulator chip may be used to adjust the voltage within the photovoltaic cell to a voltage that the lithium battery cell can receive. The voltage regulator chip may be a boost chip. Both the voltage regulator chip and the lithium battery cell may be disposed on the receiving circuit board. The voltage regulator chip may be electrically connected to the lithium battery cell of the photovoltaic cell via wires to transmit the power of the photovoltaic cell to the lithium battery cell. The photovoltaic cell may be connected to a current detection module. In practice, the current detection module may perform real-time charging current detection on the photovoltaic cell included in the associated receiver to obtain real-time charging current information. The executing entity may store the detected real-time charging current information.

[0189] The second step is to determine the charging current difference by taking the absolute value of the difference between the real-time charging current information and the pre-stored previous charging current information. The pre-stored previous charging current information may be a pre-stored charging current corresponding to the receiver detected immediately before the current time. In practice, the execution entity may determine the charging current difference by taking the absolute value of the difference between the current value represented by the real-time charging current information and the current value represented by the pre-stored previous charging current information.

[0190] The third step is to control the laser to stop the wireless charging operation in response to the charging current difference being greater than or equal to a preset charging current difference threshold. The preset charging current difference threshold can be a pre-set charging current difference. When the charging current difference is greater than or equal to the preset charging current difference threshold, it can be understood that the laser emitted by the transmitter is not received by the receiver, and therefore the charging current of the receiver is instantaneously reduced. Thus, when the instantaneous reduction in the charging current of the receiver is detected, it can be determined that the laser emitted by the transmitter is not received by the receiver, and the laser emission can be shut down, thereby reducing the waste of electrical resources.

[0191] The fourth step is to send the preset charging anomaly information to the associated terminal device. The preset charging anomaly information can be information indicating a laser wireless charging anomaly. The associated terminal device can be the user's mobile phone. This alerts the user to the laser wireless charging anomaly, allowing them to restart wireless charging or inspect the laser or receiver.

[0192] The above-mentioned first to fourth steps, as an inventive point of an embodiment of the present application, solve the second technical problem mentioned in the background technology: "For laser wireless power supply, when there is an obstruction between the laser and the receiver, the laser will still emit laser light, but the laser light cannot be irradiated onto the receiver to charge the smart door lock, thereby further leading to a waste of electric resources." The reasons for further leading to the waste of electric resources are as follows: For laser wireless power supply, when there is an obstruction between the laser and the receiver, the laser will still emit laser light, but the laser light cannot be irradiated onto the receiver to charge the smart door lock. If the above-mentioned factors are solved, the waste of electric resources can be further reduced. In order to achieve this effect, the present application also includes: first, performing real-time charging current detection on the associated receiver to obtain real-time charging current information. In this way, it can be determined whether the receiver receives the laser light of the laser and performs photoelectric conversion. Secondly, the absolute value of the difference between the above-mentioned real-time charging current information and the pre-existing charging current information is used to determine the charging current difference. In this way, the current change of the photovoltaic cell can be determined. Then, in response to the charging current difference being greater than or equal to a preset charging current difference threshold, the laser is controlled to stop the wireless charging operation. Thus, when it is detected that the charging current of the receiver decreases instantaneously, it can be determined that the laser emitted by the transmitter is not received by the receiver, thereby shutting down the laser emission, thereby reducing the waste of electrical resources. Finally, the preset charging abnormality information is sent to the associated terminal device. Thus, the user can be reminded of the abnormality of the laser wireless charging, so as to restart the wireless charging or check the laser or receiver. Thus, the charging current of the receiver can be detected in real time, so that when it is detected that the charging current of the receiver decreases instantaneously, it can be determined that the laser emitted by the transmitter is not received by the receiver, thereby shutting down the laser emission, thereby reducing the waste of electrical resources.

[0193] In some optional implementations of some embodiments, the execution subject may control the associated transmitter to perform a laser activation operation according to the target wireless charging activation information by executing the following steps:

[0194] The first step is to determine whether the remaining power of the associated smart door lock meets a preset charging power condition. The preset charging power condition may be that the remaining power is less than or equal to a preset high power threshold. The preset high power threshold may be 20%. This allows the smart door lock to be charged when the power level is at a moderate level, ensuring that the smart door lock maintains a sufficient power level for a long period of time, preventing the smart door lock from running out of power in special situations such as power outages, which could affect user use.

[0195] In the second step, in response to determining that the remaining power of the smart door lock meets the preset charging power condition, it is determined whether the current time point meets the preset rest time condition. The preset rest time condition may be that the current time point is within the late night time range. The late night time range may be 12:00 PM to 3:00 AM.

[0196] In the third step, in response to determining that the current time point satisfies the preset rest time condition, target wireless charging activation information is generated. In this case, the charging time point included in the target wireless charging activation information may be the current time point. This allows the smart door lock to be charged during periods of low user activity, reducing the impact of user activity on the charging of the smart door lock and the impact of the laser on the user.

[0197] In step 4, in response to determining that the current time point does not meet the preset rest time condition, the current date is obtained. The current date may be today's date. For example, the current date may be October 1, 2023.

[0198] In a fifth step, based on the current date, a preset wireless charging time prediction model corresponding to the current date is selected from a set of preset wireless charging time prediction models. The set of preset wireless charging time prediction models may include preset charging time prediction models corresponding to holidays, rest days, and weekdays. The preset wireless charging time prediction model may be a pre-trained machine learning model that takes the current date as input and outputs a wireless charging time series. For example, the machine learning model may be a support vector machine model or a decision tree model. Rest days may represent Saturdays and Sundays that are not holidays or workdays. For example, in response to determining that the current date represents a workday, the execution entity selects the preset charging time prediction model corresponding to a workday from the set of preset wireless charging time prediction models. In response to determining that the current date represents a rest day, the execution entity selects the preset charging time prediction model corresponding to a rest day from the set of preset wireless charging time prediction models. In response to determining that the current date represents a holiday, the execution entity selects the preset charging time prediction model corresponding to a holiday from the set of preset wireless charging time prediction models.

[0199] Furthermore, each training sample in the training sample set of the preset wireless charging time prediction model may include a current date sample and a wireless charging time series sample. The current date sample may be a historical date when the user used the smart door lock. The wireless charging time series sample may be time points within the current date sample when the user did not operate the smart door lock. "Not operating the smart door lock" can be understood as the smart door lock not detecting any operation. If the wireless charging device is equipped with an object detection sensor, the wireless charging time series sample may also be time points within the current date sample when the user did not operate the smart door lock and the object detection sensor did not detect any object. Specifically, the wireless charging time series sample corresponding to the current date sample may be determined by the following steps: First, obtaining time points within the current date sample when the user did not operate the smart door lock. Then, determining each of the time points that meets a preset time interval condition as a wireless charging time series sample. The preset time interval condition may be that the time interval between a time point and the next and closest operation time point is greater than or equal to a preset time interval threshold. As an example, the preset time interval threshold may be 2 hours. The aforementioned operation time point may be the time point at which the user operates the smart door lock. It is understood that different preset wireless charging time prediction models utilize different training sample sets. For example, the training sample set for the preset wireless charging time prediction model for weekdays includes all current date samples corresponding to weekdays.

[0200] Step 6: Input the current date into the wireless charging time prediction model to obtain a wireless charging time series.

[0201] Step 7: Filter out a wireless charging time that meets a preset proximity time condition from the wireless charging time sequence as the target wireless charging time. The preset proximity time condition may be a wireless charging time in the wireless charging time sequence that is closest to the current time point and is located after the current time point.

[0202] Step 8: Generate target wireless charging start information based on the target wireless charging time. In practice, the execution entity may determine the target wireless charging time as the charging start time included in the target wireless charging start information. The target wireless charging start information may be "charge the receiver at the target wireless charging time."

[0203] In the ninth step, according to the generated target wireless charging start-up information, the associated transmitter is controlled to perform a laser start-up operation.

[0204] The above-mentioned first to ninth steps, as an inventive feature of the embodiments of this application, solve the third technical problem mentioned in the background technology: "When the smart door lock is used for laser wireless charging during a period of high usage, the laser light emitted by the laser will be blocked multiple times, so that it cannot illuminate the receiver, causing the wireless charging process to be interrupted multiple times, resulting in low charging efficiency, and the laser light will also cause harm to the user's eyes." The reasons for the low charging efficiency and harm to the user are as follows: When the smart door lock is used for laser wireless charging during a period of high usage, the laser light emitted by the laser will be blocked multiple times, so that it cannot illuminate the receiver, causing the wireless charging process to be interrupted multiple times, resulting in low charging efficiency, and the laser light will also cause harm to the user's eyes. If the above factors are resolved, the charging efficiency can be further improved and the harm to the user can be reduced. To achieve this effect, the present application also includes: when the battery level of the smart door lock is at a medium level, determining whether the smart door lock can be laser charged at the current time. First, if the current time is late at night, the smart door lock can be laser charged at the current time. Then, if the current time is not late at night, the corresponding wireless charging time prediction model can be selected based on the current date. The current date is then input into the wireless charging time prediction model, and the time with less user activity is used as the charging time. Finally, when the charging time arrives, the smart door lock is laser charged. The wireless charging time prediction model can be trained based on the user's smart door lock usage habits, and corresponding models can be trained separately for weekends, weekdays, and holidays to improve the model's accuracy. Thus, based on the date, time, and user usage habits, the smart door lock can be charged during periods when the user uses the smart door lock less frequently. This reduces the impact of opening and closing the door on wireless charging, reduces the number of interruptions during the wireless charging process, and improves charging efficiency. This also reduces the harm caused by the laser to the user.

[0205] Step 802 : Perform current detection on each light energy conversion component in the associated light energy conversion component group to obtain a current information set of the corresponding light energy conversion component group.

[0206] In some embodiments, the execution entity may perform current detection on each light energy conversion element in the associated light energy conversion element group to obtain a current information set corresponding to the light energy conversion element group. Each light energy conversion element in the light energy conversion element group may be provided on the emitter. In practice, for each light energy conversion element in the associated light energy conversion element group, the execution entity may perform current detection on the light energy conversion element through a current detection module connected to the light energy conversion element to obtain current information corresponding to the light energy conversion element. The light energy conversion element may be a silicon photocell. The current detection module may be a module for detecting the magnitude of the current converted by the silicon photocell. For example, the current detection module may be a Hall sensor current detection module or a resistive current detection module.

[0207] Step 803 : Determine whether each current information in the current information set meets a preset charging condition.

[0208] In some embodiments, the execution entity may determine whether each current information in the current information set satisfies a preset charging condition. The preset charging condition may be that the current value corresponding to the current information is greater than or equal to a preset current threshold. The preset current threshold may be a minimum current that can be converted by the light energy conversion element when the reflector on the receiver reflects the laser light to the light energy conversion element.

[0209] Step 804 : In response to determining that each current information in the current information set satisfies a preset charging condition, controlling the transmitter to perform a wireless charging operation on the associated receiver.

[0210] In some embodiments, the execution entity may, in response to determining that each current information in the current information set satisfies the preset charging condition, control the transmitter to perform a wireless charging operation on the associated receiver. In practice, in response to determining that each current information in the current information set satisfies the preset charging condition, the execution entity may continue to control the laser driver included in the transmitter to drive the laser to emit laser light to perform laser charging on the associated receiver. Furthermore, in response to determining that the current information set includes current information that does not satisfy the preset charging condition, the transmitter may be controlled to perform an angle adjustment operation.

[0211] Optionally, the above-mentioned execution subject may further perform the following steps to control the transmitter to perform an angle adjustment operation:

[0212] The first step is to control the laser to move to a preset position in response to determining that each current information in the current information set does not meet the preset charging condition. The preset position may be an extreme position within the moving range of the laser. For example, the preset position may be the leftmost and uppermost position within the movable range of the laser. Specifically, the horizontal stepping motor included in the pan-tilt component connected to the laser can drive the laser to move to the leftmost side, and the vertical stepping motor included in the pan-tilt component can drive the laser to move to the uppermost side.

[0213] The second step is to control the laser to perform a first movement operation and perform a first real-time current detection on each light energy conversion element in the light energy conversion element group according to a preset movement information sequence, thereby obtaining first real-time current information corresponding to the light energy conversion element group. Each preset movement information in the preset movement information sequence may include a preset movement direction and a preset movement distance. The preset movement information sequence may be a pre-set movement path of the laser.

[0214] Specifically, the preset movement information sequence can be determined based on the preset position. For example, when the laser moves to the far left, the first N preset movement information in the preset movement information sequence can represent a rightward movement of a preset horizontal distance. This preset horizontal distance can be less than the width of the photovoltaic cell on the receiver. N is a preset number. The sum of the N preset horizontal distances can equal the horizontal movement limit of the laser. The N+1th preset movement information in the preset movement information sequence can represent a downward movement of a preset vertical distance. This preset vertical distance can be less than the height of the photovoltaic cell on the receiver. The N+1+Nth preset movement information in the preset movement information sequence can represent a leftward movement of a preset horizontal distance. This means that the laser moves in a serpentine manner, with each horizontal movement distance being less than the width of the photovoltaic cell on the receiver and each vertical movement distance being less than the height of the photovoltaic cell on the receiver. During the movement process, the execution entity can detect the current of the photoelectric conversion element in the first movement operation using a current detection module connected to the photoelectric conversion element to obtain first real-time current information corresponding to the photoelectric conversion element group. Therefore, through the above-mentioned preset movement information sequence, scanning can be performed within the movement range of the laser, so as to preliminarily determine the position of the receiver.

[0215] In the third step, in response to the detected first real-time current information corresponding to any photoelectric conversion element meeting the above-mentioned preset first real-time charging condition, the laser is controlled to perform a second movement operation according to the target movement information sequence, and a second real-time current detection is performed on each photoelectric conversion element in the above-mentioned photoelectric conversion element group to obtain the first real-time current information corresponding to the above-mentioned photoelectric conversion element group. The above-mentioned preset first real-time charging condition may be that the current value corresponding to the first real-time current information is greater than or equal to a preset current threshold. Each target movement information in the above-mentioned target movement information sequence may include a target movement direction and a target movement distance, and the target movement distance included in any target movement information is less than the preset movement distance included in any preset movement information. The above-mentioned target movement sequence can be determined by the position of any of the above-mentioned detected photoelectric conversion elements. Therefore, when it is detected that any photoelectric conversion element senses the reflected laser light and performs photoelectric energy conversion, the laser can be further controlled to move a smaller distance to fine-tune the laser angle so that the laser can be more accurately aligned with the receiver.

[0216] In a fourth step, in response to the detected second real-time current information corresponding to each light energy conversion element satisfying the preset second real-time charging condition, the transmitter is controlled to perform a wireless charging operation. The preset second real-time charging condition may be that the current value corresponding to the second real-time current information is greater than or equal to a preset current threshold.

[0217] In some optional implementations of some embodiments, in response to the detected first real-time current information corresponding to any one of the photoenergy conversion elements meeting the preset first real-time charging condition, the execution entity may control the laser to perform a second movement operation according to the target movement information sequence, and perform a second real-time current detection on each photoenergy conversion element in the photoenergy conversion element group to obtain the first real-time current information corresponding to the photoenergy conversion element group by executing the following steps:

[0218] In the first step, in response to the detected first real-time current information corresponding to any of the light energy conversion components satisfying the preset first real-time charging condition, a position identifier corresponding to the light energy conversion component is determined. The position identifier may be an identifier indicating the location of the light energy conversion component. For example, the position identifier may be "light energy conversion component, lower right."

[0219] The second step is to determine the target movement information sequence based on the above-mentioned position identifier. In practice, the above-mentioned execution entity can determine the target movement information sequence based on the above-mentioned position identifier and the preset movement information sequence configuration information set. Among them, each preset movement information sequence configuration information in the above-mentioned preset movement information sequence configuration information set may include a preset position identifier and a preset movement information sequence. As an example, first, the above-mentioned execution entity may determine the preset movement information sequence configuration information including the same preset position identifier as the above-mentioned position identifier as the target movement information sequence configuration information. Then, the above-mentioned execution entity may determine the preset movement information sequence included in the above-mentioned target movement information sequence configuration information as the target movement information sequence. Specifically, when the above-mentioned position identifier is "light energy conversion element, lower right". The first M target movement information of the above-mentioned target movement information sequence can represent the horizontal distance of the target moving to the right. The above-mentioned target horizontal distance can be less than the width of the reflector. The M target horizontal distances can be equal to the width of the photovoltaic cell. The first M+1 target movement information of the above-mentioned target movement information sequence can represent the vertical distance of the target moving downward. The above-mentioned target vertical distance can be less than the height of the reflector.

[0220] The third step is to control the laser to perform a second movement operation based on the target movement information sequence, and to perform a second real-time current measurement on each of the light energy conversion components in the light energy conversion component group, thereby obtaining first real-time current information corresponding to the light energy conversion component group. This can be understood as the laser moving in a serpentine pattern, with each horizontal movement distance being less than the width of the reflector and each vertical movement distance being less than the height of the reflector. During this movement, the executing entity can perform current measurement on the light energy conversion components in the second movement operation using a current detection module connected to the light energy conversion components, thereby obtaining second real-time current information corresponding to the light energy conversion component group.

[0221] Optionally, after controlling the transmitter to perform a wireless charging operation on the associated receiver in response to determining that each current information in the current information set satisfies the preset charging condition, the execution subject may further perform the following steps:

[0222] In the first step, an associated object detection sensor is used to detect an object within a target range to determine whether an object is within the target range. The target range may include the range corresponding to the transmission path of the transmitter. The object detection sensor may be a proximity sensor or a human presence detection sensor.

[0223] In the second step, in response to determining that there is an object within the target range, the transmitter is controlled to stop the wireless charging operation. In this way, laser charging can be stopped when an object is detected to be blocking the target range, thereby avoiding waste of power resources and the impact of laser on the human body.

[0224] Optionally, after controlling the transmitter to wirelessly charge the associated receiver in response to determining that each current information in the current information set satisfies the preset charging conditions, the execution entity may further control the transmitter to cease wireless charging in response to detecting a door opening operation corresponding to the associated smart door lock. In practice, the transmitter is controlled to cease wireless charging in response to detecting a door opening operation on the smart door lock. This prevents the laser from affecting users entering the door.

[0225] The aforementioned embodiments of the present application have the following beneficial effects: the wireless charging methods of some embodiments of the present application can facilitate user use and reduce waste of electrical resources. Specifically, the inconvenience and waste of electrical resources caused by battery power supply are: due to the high power consumption of the smart door lock's electrical load, frequent battery replacement is required. For laser wireless power supply, the receiver is relatively small, and manual adjustment of the laser transmitter to align with the receiver is less accurate. This can lead to significant deviations in the angle at which the laser light emitted by the laser hits the receiver, causing some laser light not to hit the receiver. Based on this, some embodiments of the present application provide a wireless charging method. This wireless charging method first controls an associated transmitter to perform a laser activation operation based on target wireless charging activation information. This activates the laser. Then, current detection is performed on each light energy conversion element in the associated light energy conversion element group to obtain a current information set corresponding to the light energy conversion element group, wherein each light energy conversion element in the light energy conversion element group is disposed on the transmitter. Subsequently, the feedback laser can be used to determine whether each current information in the current information set meets preset charging conditions. Thus, the current conditions of each light energy conversion component on the above-mentioned transmitter can be detected to determine whether each light energy conversion component receives the laser reflected by the reflector on the receiver. Finally, in response to determining that each current information in the above-mentioned current information set meets the above-mentioned preset charging conditions, the above-mentioned transmitter is controlled to perform a wireless charging operation on the associated receiver. Thus, when it is determined that each of the above-mentioned light energy conversion components receives the laser reflected by the reflector on the receiver, that is, when the laser completely covers the reflector on the receiver, the laser charging operation can be performed. Because the wireless charging method is adopted, there is no need for the user to frequently replace the battery of the smart door lock, which can be convenient for the user to use. Also, because the laser charging operation is performed when the laser completely covers the reflector on the receiver, it can avoid the laser irradiation outside the receiver, thereby reducing the waste of electrical resources. Therefore, the wireless charging method of some embodiments of the present application can be convenient for users to use and reduce the waste of electrical resources.

The lithium battery cell can be electrically connected to the door lock circuit board within the smart door lock. The door lock circuit board can be equipped with a power management chip and a power interface.

The adjustment member may be connected to the exterior of the transmitter housing. The transmitter housing may be the outer shell of the transmitter. The adjustment member may be used to connect the transmitter to another object. Specifically, one adjustable end of the adjustment member may be connected to the transmitter. The other end of the adjustment member may be connected to another object. For example, the other end of the adjustment member may be fixed to a roof. Furthermore, the other end of the adjustment member may be fixed to a location on the roof where a power cord is installed, so that the power supply assembly included in the transmitter can be electrically connected to the power cord.

[0239] In some optional embodiments of the present application, a laser wireless charging method for a smart device is proposed. FIG10 is a flow chart of the laser wireless charging method for a smart device proposed in the present application. As shown in FIG10 , the method includes:

[0240] S101: Detect whether preset charging conditions are met.

[0241] First, this method is applicable to a device with a laser transmitter. In one embodiment, a central control unit is provided in the smart door lock, capable of transmitting commands to the laser transmitter and the laser receiver, enabling interaction between the two. Alternatively, each transmitter and receiver has a control unit for executing the interactive method of laser wireless charging. The preset charging conditions are intended to ensure that laser light can be received and energy converted during the laser transmission process, while also providing protection for people. These preset charging conditions may include: accurate positioning of the laser transmitter and the laser receiver (i.e., turning on the laser transmitter ensures that the light source is accurately projected onto the device's receiver, which then converts the energy and charges the lithium battery); detecting the presence of living organisms within the laser's proximity (to avoid harm to humans or animals); and detecting whether the current illumination level of the receiver is below a first threshold (to avoid charging when the battery is fully charged). Charging can only proceed if at least one or both of these conditions are met. The specific conditions can be set based on the user's actual needs, and other preset charging conditions can also be added.

[0242] Among them, only one laser transmitting end can be set to emit laser in all directions. There can be multiple smart devices where the laser receiving end is located. The transmitting end can emit laser to each smart device through position adjustment and calibration to achieve the purpose of wireless charging.

[0243] S102: When a preset charging condition is met, transmit laser light to the laser receiving end at an initial transmission power.

[0244] Taking the three conditions mentioned above as an example, if the position is accurate, there are no living objects within the preset range, and the current battery level is below the first battery level threshold, the preset charging condition is determined to be met. At this time, the laser transmitter transmits laser light to the laser receiver at the initial transmission power.

[0245] S103 : In response to the first instruction fed back by the laser receiving end according to the power adjustment information, reduce the transmission power according to a preset adjustment strategy.

[0246] The power adjustment information includes at least the current power level of the smart device where the laser receiving end is located. The laser receiving end will collect the current power level in real time. When the power level reaches a certain threshold (for example, a first power level threshold), the receiving end will feedback a first instruction to the transmitting end. At this time, the transmitting end will reduce the transmission power according to the preset adjustment strategy.

[0247] In addition, it can also include the relationship between the current number of users and the preset number of users, or historical usage data. For example, if the smart device is a smart door lock and detects that the current number of users is 2 at 7 o'clock in the evening, which is lower than the preset number of 3, then it determines that someone may return in the future, and sends a first instruction to reduce the transmission power. The purpose of reducing the transmission power is threefold. First, it will reduce the radiation generated when the user returns, reducing damage to people. Second, it is to reduce the current. Fast-charging batteries use high current losses, so trickle charging by adjusting the power is better for the battery, and low current charging is more effective. Third, trickle charging does not cause the battery to heat up, which plays a role in battery protection.

[0248] The transmission power is reduced according to a preset adjustment strategy. The adjustment strategy specifically determines the adjusted transmission power based on the current power level, the current time, the number of people in the room, and historical usage data. For example, the smart device is a door lock. The battery is now charged to 95%, and the transmission power is assumed to be 20 units. The current time is 2 a.m. At this time, based on historical usage data, it is determined that the user does not usually use the door lock at this time (2 a.m.). The power can be reduced to 5 units to ensure that the door lock is fully charged before the user uses it before dawn. The smart devices here can also include independent smart door locks, smart electronic scales, smart vertical air conditioners, wireless charging shavers, etc. In addition, in one embodiment, the smart device can be a smart door lock, which is installed on a smart door and is used to obtain various data information of the smart door (such as power level) and execute the above-mentioned laser wireless charging method.

[0249] S104 , in response to the second instruction fed back by the laser receiving end according to the power adjustment information, stop emitting laser light to the laser receiving end.

[0250] The second command can also be based on feedback from the laser receiver based on the current battery level. When the laser is fully charged, the receiver sends a second command to the transmitter, halting laser transmission to avoid wasting energy. Furthermore, this can be determined based on the relationship between the number of users and a preset number of users, or based on historical usage data.

[0251] In this embodiment, a check is first performed to determine whether preset charging conditions are met. If so, laser light is emitted to the laser receiving end at the initial transmission power. In response to a first instruction fed back by the laser receiving end based on power adjustment information, the transmission power is reduced according to a preset adjustment strategy. Simultaneously, in response to a second instruction fed back by the laser receiving end based on power adjustment information, laser light emission to the laser receiving end is stopped. Compared to related technologies, this embodiment determines whether charging is currently possible by setting preset charging conditions. Furthermore, the initial transmission power is reduced or stopped based on the first and second instructions fed back by the laser receiving end, thereby achieving flexible control of the laser transmission power during the charging process and improving the technical problem of inaccurate laser transmission power control in existing technologies.

[0252] Optionally, detecting whether the preset charging conditions are met includes: detecting whether the laser emitting end and the laser receiving end have completed position calibration; and / or detecting whether there is a living object within a preset range of the laser emitting end; and / or detecting whether the current power of the laser receiving end is lower than a first power threshold; wherein, when the position calibration has been completed, there is no living object within the preset range and the current power is lower than the first power threshold, it is determined that the preset charging conditions are met.

[0253] In this embodiment, the preset charging conditions are intended to ensure that laser light can be received and energy converted during the laser emission process, while also protecting people. In this embodiment, the preset charging conditions are accurate positioning of both ends, detection of whether there are living objects within the laser's vicinity, and detection of whether the current light level at the receiving end is below a first threshold. These three conditions must be met simultaneously for the preset charging conditions to be considered met. Of course, these can also be set based on the user's actual situation, and other preset charging conditions can be added. By setting the preset charging conditions, it is possible to ensure that the light source is accurately projected onto the device's receiving device to achieve the charging process, while avoiding damage to people and energy waste.

[0254] Optionally, in response to the first instruction fed back by the laser receiving end based on the power adjustment information, the transmission power is reduced according to a preset adjustment strategy, including: after receiving the first instruction, obtaining real-time charging information, historical usage data and the current number of people; the charging information includes the current power level and the current time; according to the relationship between the current number of people and the preset number of users, determining the target transmission power, and transmitting the laser to the laser receiving end according to the target transmission power; and / or, according to the current power level and the current time, comparing with the historical usage data, determining the target transmission power, and transmitting the laser to the laser receiving end according to the target transmission power; wherein the target transmission power is lower than the initial transmission power.

[0255] In this embodiment, after receiving the first instruction, it means that the current power level is greater than the first threshold, so the power can be appropriately reduced. However, reducing the power is not directly reducing it to a fixed value, but can be done dynamically. First, obtain the charging information, including the current power level and the current time, and obtain historical usage data. The historical usage data here includes the user's usage time and frequency of use of the smart device. By judging the current time, it is predicted whether the user is likely to use the door lock in the future (or when the door lock is expected to be used next time), and then determine the transmission power.

[0256] Let's take the smart door lock as an example. Now the battery is charged to 95%, the transmission power is 20 units, and the current time is 2 a.m. At this time, combined with historical usage data, it can be judged that the user does not use the door lock at this time (2 a.m.). The power can be reduced to 5 units to ensure that the battery is fully charged before the user uses the door lock before dawn.

[0257] In another scenario, the battery is now 95% charged and the transmit power is also 20 units. It is currently 4:00 PM, and the door lock will be used frequently in the next few hours. The transmit power can be adjusted to 15 units to fully charge the door lock as quickly as possible.

[0258] In addition, the charging information may also include the charging time or other parameters. If the charging time is too long (greater than a certain time threshold), the transmission power will be set to 18 units to fully charge the door lock as soon as possible, etc., allowing users to make personalized settings.

[0259] In another possible embodiment, the target transmit power can be determined based on the relationship between the current number of people in the room and the preset number of users. Specifically, when a user opens the door and enters, an infrared acquisition and detection device can be used to determine how many people have entered. Then, at a certain time point (e.g., 7 p.m.), it is determined that there are only two people in the room, which is less than the preset number of three. This indicates that the room is likely to be used again in the future. At this time, the laser can be emitted at the target transmit power to reduce the laser radiation, thereby reducing the radiation to the user and protecting the battery.

[0260] Optionally, when the preset charging conditions are met, after emitting laser light to the laser receiving end at the initial emission power, the method further includes: during the laser emission process, periodically detecting whether there is a living object within a preset range of the laser emitting end according to a preset time period; and stopping emitting laser light to the laser receiving end when the presence of a living object is detected.

[0261] In this embodiment, to avoid direct laser damage to humans or animals, laser emission is stopped if a living organism is detected within a preset range of the laser emitter (generally about 3 meters around the laser emission path). Specifically, the preset time period can be set to 0.5 seconds, meaning that the presence of a living organism near the laser emitter is detected every 0.5 seconds.

[0262] Correspondingly, this embodiment also provides another laser wireless charging method for smart devices, which is applied to a laser receiving end, which is used to provide power to the smart device. Specifically, the method includes: real-time acquisition of the smart device's power level; when the current power level exceeds a first power threshold, sending a first instruction to the laser transmitting end to reduce the laser transmitting power; and when the current power level is fully charged, sending a second instruction to the laser transmitting end to stop emitting laser light.

[0263] This embodiment also provides another laser wireless charging method for smart devices, as shown in FIG11 , which shows a schematic diagram of the interaction process between the laser transmitting end and the laser receiving end, specifically including:

[0264] S201, the laser transmitter determines whether the preset charging conditions are met, if so, enters S202;

[0265] In this embodiment, the preset charging conditions include accurate dual-terminal position calibration, detecting the presence of living objects within the laser's proximity, and detecting whether the current light level at the receiving end is below a first threshold. These three conditions must be met simultaneously for the preset charging conditions to be considered met. Of course, these conditions can be customized based on the user's actual needs, and other preset charging conditions can be added.

[0266] S202, the laser transmitting end transmits a laser to the laser receiving end according to the initial transmitting power;

[0267] S203, the laser receiving end determines whether the first power threshold is reached, and if so, proceeds to S204;

[0268] In this embodiment, the first instruction is fed back by the power level. In some cases, the relationship between the current number of people in the room and the preset number of people, or the historical usage data of the smart device can also be set as the judgment condition for feeding back the first instruction.

[0269] S204, the laser receiving end feeds back a first instruction to the laser emitting end;

[0270] In this embodiment, the first power threshold is set to 90%, that is, when the laser receiving end determines that the light is 90% full, it feeds back the first instruction to the laser emitting end.

[0271] S205, in response to the first instruction, the laser transmitting end dynamically reduces the transmitting power;

[0272] After receiving the first instruction, it indicates that the current power level is greater than the first threshold, so the power can be appropriately reduced. Charging information, including the current power level and the current time, is obtained, and historical usage data is obtained. The historical usage data here includes the user's usage time and frequency of the smart device. By judging the current time, it is predicted whether the user is likely to use the door lock in the future (or when the door lock is expected to be used next time), and then the transmission power is determined.

[0273] S206, the laser receiving end determines whether the battery is fully charged, if so, proceeds to S207;

[0274] S207, the laser receiving end feeds back a second instruction to the laser emitting end;

[0275] S208: In response to the second instruction, the laser emitting end stops emitting laser light.

[0276] It should be noted that current home appliances are becoming increasingly versatile. For example, in this embodiment, since the smart door lock, in addition to basic unlocking functionality, also features a peephole monitoring function, it not only provides a better user experience but also places higher demands on battery life. The current market practice is to use two lithium batteries, but this still only provides a battery life of approximately four months. However, the long-distance wireless charging system enables users to use the door lock 24 / 7 without concerns about battery life. Furthermore, the control of the power transmission device significantly improves the service life and safety of the entire system. Preset charging conditions are also set to determine whether charging is currently possible. Furthermore, the initial transmission power is reduced or stopped based on the first and second commands fed back by the laser receiver, thereby achieving flexible control of the laser transmission power during the charging process and improving the technical problem of inaccurate laser transmission power control in the existing technology.

[0277] Furthermore, as a specific implementation of the method shown in Figures 10 and 11, this embodiment provides a laser wireless charging device for a smart device, as shown in Figure 12, the device includes: a detection unit 31, a transmitting unit 32, a first execution unit 33 and a second execution unit 34.

[0279] The transmitting unit 32 is configured to transmit laser light to the laser receiving end at an initial transmitting power when the preset charging condition is met;

[0280] The first execution unit 33 is configured to respond to the first instruction fed back by the laser receiving end according to the power adjustment information and reduce the transmission power according to a preset adjustment strategy;

[0281] The second execution unit 34 is configured to stop emitting laser light to the laser receiving end in response to a second instruction fed back by the laser receiving end according to the power adjustment information;

[0282] The power adjustment information at least includes the current power level of the smart device where the laser receiving end is located.

[0283] In a specific application scenario, the detection unit 31 is specifically configured to detect whether the laser emitting end and the laser receiving end have completed position calibration; and / or, detect whether there is a living object within the preset range of the laser emitting end; and / or, detect whether the current power of the laser receiving end is lower than a first power threshold; wherein, when the position calibration has been completed, there is no living object within the preset range and the current power is lower than the first power threshold, it is determined that the preset charging condition is met.

[0284] In a specific application scenario, the first execution unit 33 is specifically configured to obtain real-time charging information, historical usage data and the current number of people after receiving the first instruction; the charging information includes the current power level and the current time; based on the relationship between the current number of people and the preset number of users, determine the target transmission power, and transmit the laser to the laser receiving end according to the target transmission power; and / or, based on the current power level and the current time, compare with the historical usage data to determine the target transmission power, and transmit the laser to the laser receiving end according to the target transmission power; wherein, the target transmission power is lower than the initial transmission power.

[0285] In a specific application scenario, the first execution unit 34 is specifically configured to periodically detect whether there is a living object within the preset range of the laser emitting end according to a preset time period during the laser emission process; if the presence of a living object is detected, stop emitting laser light to the laser receiving end.

[0286] Furthermore, as a specific implementation of the method shown in Figures 10 and 11, this embodiment provides a wireless charging device, in which the laser receiving end is used to provide power to the smart device. As shown in Figure 13, the device includes: an acquisition unit 41, a first sending unit 42 and a second sending unit 43.

[0287] The collection unit 41 is configured to collect the power of the smart device in real time;

[0288] The first sending unit 42 is configured to send a first instruction to the laser emitting end when the current power level is higher than the first power level threshold, so that the laser emitting end reduces the transmission power;

[0289] The second sending unit 43 is configured to send a second instruction to the laser emitting end when the current power is fully charged, so as to make the laser emitting end stop emitting laser light.

[0290] For other corresponding descriptions of the functional units involved in the wireless charging device provided in this embodiment, reference can be made to the corresponding descriptions in Figures 10 and 11, which will not be repeated here.

[0291] In some optional embodiments of the present application, a wireless charging alignment method is provided to achieve wireless alignment during the wireless charging process. Figure 14 is a schematic diagram of an application scenario of a smart door lock infrared charging device in the wireless charging alignment method provided in an optional embodiment of the present application.

[0292] In the application scenario of Figure 14, it includes: a horizontal stepper motor, a vertical stepper motor, a Bluetooth SOC, a corner cube prism, and a laser receiving area. That is, the wireless transmitting device may include: a horizontal stepper motor, a vertical stepper motor, and a Bluetooth SOC. That is, the infrared laser transmitter can be controlled to rotate by the horizontal stepper motor and the vertical stepper motor. Among them, an infrared laser transmitter is connected to the right connection of the Bluetooth SOC. Bluetooth SOC may refer to a Bluetooth system chip. The laser receiving area may refer to a laser sensor. The above-mentioned laser sensor is integrated into the above-mentioned smart door lock, and a corner cube prism (optical component) is integrated on the surface of the above-mentioned laser sensor.

[0293] In actual operation, after the infrared laser transmitter and door lock are installed, automatic alignment is required. During the automatic alignment process, the infrared laser transmitter's vertical and horizontal stepper motors control the infrared laser transmitter to automatically scan the appropriate area. When the infrared laser is aligned with the receiving area, the laser beam returns to the transmitter along its original path under the reflection of the corner cube prism. After the infrared laser transmitter's laser sensor senses the beam, it will reduce the control speed of the stepper motor and enter the fine-tuning stage until the laser beam is fully aligned, completing the entire automatic calibration process. The transmitter's Bluetooth SOC will know whether the calibration is complete through the laser sensor.

[0294] Figure 15 is a flow chart of a wireless alignment charging method proposed in an optional embodiment of the present application. In this wireless charging alignment method, the smart door lock wireless charging device includes: a wireless transmitter, an infrared laser transmitter, and a laser sensor. The laser sensor is integrated into the smart door lock, and an optical component is integrated on the surface of the laser sensor. The method includes the following steps:

[0295] Step 601: In response to receiving a calibration instruction, control the infrared laser transmitter to scan a preset area.

[0296] In some embodiments, the executor of the wireless charging alignment method (e.g., a smart door lock wireless charging device) can, in response to receiving a calibration command, control the infrared laser transmitter to scan a preset area. For example, the wireless transmitter can include a Bluetooth system chip, a horizontal stepper motor, and a vertical stepper motor. The horizontal stepper motor can be a stepper motor that rotates horizontally. The vertical stepper motor can be a stepper motor that rotates vertically. The Bluetooth system chip can be a Bluetooth chip built into the infrared laser transmitter. For example, the Bluetooth system chip can be a Bluetooth SoC chip. The infrared laser transmitter can be a transmitter that emits infrared laser light and performs infrared laser charging. The smart door lock can be a smart fingerprint lock or a smart password lock. The laser sensor is used to receive and sense infrared laser light. The optical component can be a component that receives infrared laser light. For example, the optical component can be a corner cube prism. The corner cube prism is attached to the surface of the laser sensor. The preset area can be the range area of ​​the smart door lock designated by technicians after the infrared transmitter and smart door lock are installed. Specifically, the infrared laser emitter can be controlled to emit infrared laser light toward a preset area. Reflection of the laser light from the optical component indicates that the calibration location has been scanned. The infrared transmitter can also emit infrared light toward the laser sensor of the smart door lock to charge it. Horizontal and vertical stepper motors control the horizontal and vertical rotation of the infrared laser emitter.

[0297] Step 602: In response to detecting that the infrared laser emitter has scanned the optical component, the position of the scanned optical component is recorded.

[0298] In some embodiments, the execution entity may record the scanned position of the optical component in response to detecting that the infrared laser emitter has scanned the optical component. Specifically, the three-dimensional coordinates of the optical component may be recorded. For example, a spatial coordinate system may be pre-established to determine the three-dimensional spatial position of the optical component.

[0299] Step 603: Control the infrared laser emitter to emit an infrared laser beam toward the optical component to obtain optical indication information, and acquire the relative position of the light according to the optical indication information.

[0300] In some embodiments, the execution entity may control the infrared laser emitter to emit an infrared laser beam toward the optical component to obtain optical indication information, and determine the relative position of the light beam based on the optical indication information. The optical indication information may include a schematic diagram of a light spot of the optical component, wherein the schematic diagram of the light spot of the optical component shows the laser light spot. Specifically, a camera may be used to capture a schematic diagram of the light spot of the laser beam emitted toward the optical component within the optical component, as the schematic diagram of the light spot of the optical component.

[0301] In practice, the execution entity can control the infrared laser emitter to emit an infrared laser beam toward the optical component through the following steps: First, construct a three-dimensional spatial coordinate system with the center position of the infrared transmitting device as the origin. Second, determine the three-dimensional coordinates of the emitter of the infrared laser emitter's current emission hole. Third, determine the three-dimensional coordinates of the optical component corresponding to the center position of the optical component. Fourth, control the infrared laser emitter to emit an infrared laser beam in the direction of the three-dimensional coordinates of the optical component, using the three-dimensional coordinates of the emitter as the starting emission point.

[0302] In practice, the execution subject can obtain the relative position of the light by the following steps: First, perform noise reduction processing on the optical component light spot schematic diagram to generate a noise reduction optical component light spot schematic diagram. The optical component light spot schematic diagram can be subjected to noise reduction processing using an image noise elimination algorithm to generate a noise reduction optical component light spot schematic diagram. For example, the image noise elimination algorithm can be a spatial domain filtering algorithm or a transform domain filtering algorithm. Second, perform correction processing on the noise reduction optical component light spot schematic diagram to generate a corrected noise reduction optical component light spot schematic diagram. The image distortion correction algorithm can be used to correct the noise reduction optical component light spot schematic diagram to generate a corrected noise reduction optical component light spot schematic diagram. Third, determine the relative position of the center position of the corrected noise reduction optical component light spot schematic diagram and the displayed laser spot as the relative position of the light. The relative position of the light includes a horizontal offset and a vertical offset. The center position of the displayed light spot can be identified by an image recognition algorithm (for example, a pre-trained convolutional neural network). Then, the horizontal offset (lateral offset) and vertical offset between the center position of the displayed light spot and the center position of the above-mentioned schematic diagram of the correction noise reduction light screen can be determined.

[0303] Step 604: Control the infrared laser emitter to rotate according to the relative position of the light beam so that the infrared laser beam is directed toward the center position corresponding to the optical indication information.

[0304] In some embodiments, the execution entity may control the infrared laser emitter to rotate according to the relative position of the light beam, so that the infrared laser beam is directed toward the center position corresponding to the optical indication information, that is, the center position of the optical component light spot diagram.

[0305] In practice, the execution entity can control the rotation of the infrared laser emitter through the following steps: First, according to the horizontal offset included in the relative position of the light, the horizontal offset angle of the infrared laser beam is calculated. That is, the horizontal offset angle of the infrared laser beam can be calculated by trigonometric function. The horizontal offset angle has a corresponding offset direction. Second, according to the vertical offset included in the relative position of the light, the vertical offset angle of the infrared laser beam is calculated. That is, the vertical offset angle of the infrared laser beam can be calculated by trigonometric function. The vertical offset angle has a corresponding offset direction. Third, according to the horizontal offset angle and the vertical offset angle, the infrared laser emitter is controlled to rotate. The horizontal stepping motor can be controlled to horizontally offset the horizontal offset angle. The horizontal stepping motor can be controlled to vertically offset the horizontal offset angle. Thus, the infrared laser emitter is controlled to rotate.

[0306] Optionally, the recorded position information of the optical component, the optical indication information, the relative position of the light, and the identification information of the smart door lock wireless charging device are combined into an infrared charging device data file.

[0307] In some embodiments, the execution entity may combine the recorded position information of the optical component, the optical indication information, the relative position of the light, and the identification information of the smart door lock wireless charging device into an infrared charging device data file. Combining may refer to merging.

[0308] Optionally, data slicing is performed on the infrared charging device data file to obtain an infrared charging device data block group.

[0309] In some embodiments, the execution entity may perform data slicing on the infrared charging device data file to obtain an infrared charging device data block group.

[0310] In practice, the execution entity may perform data slicing on the infrared charging device data file through the following steps: First, set a data volume slicing threshold. That is, the data volume slicing threshold may be randomly set. The data volume slicing threshold may be a threshold for the maximum data capacity of a data block. The data volume slicing threshold may be 128KB. Second, generate the slicing data volume corresponding to the infrared charging device data file based on the data volume slicing threshold. First, determine the data capacity of the infrared charging device data file. Then, round up the ratio of the data capacity to the upper data volume slicing threshold to determine the slicing data volume. Third, perform data slicing on the infrared charging device data file based on the slicing data volume and the data volume slicing threshold to obtain an infrared charging device data block group. The infrared charging device data file is then data sliced ​​according to the data volume slicing threshold. That is, the maximum data capacity of an infrared charging device data block is the data volume slicing threshold.

[0311] Optionally, the following processing steps are performed for each infrared charging device data block in the infrared charging device data block group: Step 1: Digitally sign the infrared charging device data block using a preset digital signature key to obtain an infrared charging device data block signature value. For example, the digital signature key may be a signature key in a preset UKEY. Step 2: Generate a key based on the identification information. For example, the identification information may be encoded to obtain a coded identifier. The coded identifier may then be converted into a decimal number and used as a key. Step 3: Encrypt the infrared charging device data block using the key to obtain an encrypted infrared charging device data block. Step 4: Encrypt the key using a public key in a preset asymmetric key to obtain an encryption key. An asymmetric key pair may include a public key and a private key. Step 5: Sign the encrypted infrared charging device data block using the digital signature key to obtain an encrypted data block signature value. In other words, the encrypted infrared charging device data block may be digitally signed using the digital signature key to obtain an encrypted data block signature value. Step 6: Merge the infrared charging device data block signature value, the encrypted infrared charging device data block, the encryption key and the encrypted data block signature value into an encrypted data block sub-file.

[0312] In addition, due to the small storage space of the door lock system, the relevant data of the generated smart door lock is not classified and stored, which can easily cause delays in the door lock system.

[0313] Optionally, each encrypted data block sub-file is stored in an associated storage node.

[0314] In some embodiments, the execution entity may store each encrypted data block sub-file in an associated storage node.

[0315] In practice, the execution entity can store each encrypted data block subfile in an associated storage node through the following steps: First, mark the data type of each encrypted data block subfile whose data volume is less than the preset data volume as a first data type. The preset data volume can be 128KB. Second, mark the storage type of each encrypted data block subfile whose data volume is equal to the preset data volume as a second data type. Third, perform the following processing steps for each encrypted data block subfile in each encrypted data block subfile:

[0316] First, in response to the data type of the message data block to be written being a first data type, the encrypted data block subfile is stored in a first storage subnode of the storage node. The first storage subnode may be an SSD (Solid State Drive) of the storage node. Then, in response to determining that the data type of the message data block to be written is a second data type, the encrypted data block subfile is stored in a second storage subnode of the storage node. The second storage subnode may be an HDD (Hard Disk Drive) of the storage node.

[0317] The above-mentioned related content, as an inventive point of this application, solves the technical problem of "easily causing delays in the door lock system." Factors that easily cause delays in the door lock system are often as follows: due to the limited storage space of the door lock system, the generated smart door lock related data is not classified and stored, which easily causes delays in the door lock system. If the above-mentioned factors are solved, the delay of the door lock system can be reduced. To achieve this effect, first, the data type of the encrypted data block subfiles in the above-mentioned encrypted data block subfiles whose data volume is less than the above-mentioned preset data volume is marked as a first data type. Secondly, the storage type of the encrypted data block subfiles in the above-mentioned encrypted data block subfiles whose data volume is equal to the above-mentioned preset data volume is marked as a second data type. Then, for each of the above-mentioned encrypted data block subfiles, the following processing steps are performed: in response to the data type of the above-mentioned message data block to be written being the first data type, the above-mentioned encrypted data block subfile is stored in the first storage subnode of the above-mentioned storage node; in response to determining that the data type of the above-mentioned message data block to be written is the second data type, the above-mentioned encrypted data block subfile is stored in the second storage subnode of the above-mentioned storage node. This enables classified storage of encrypted data block subfiles of different data volumes, alleviating the storage pressure on the door lock system. This improves the read rate of encrypted data block subfiles and reduces the latency of the door lock system.
