[0069] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0070] The distance determination method provided in this application embodiment can be applied to, for example, Figure 1 In the application environment shown, the target device 102 includes a distance determining device 104. The distance determining device 104 detects whether the target life form 106 is approaching the target device 102. Specifically, the distance determining device 102 controls the target device to generate a real-time electromagnetic field, and based on the real-time electromagnetic field, obtains the real-time voltage value corresponding to the real-time capacitance value formed between the target device and the target life form. Then, based on the real-time voltage value, it determines the real-time distance between the target life form and the target device. It can be understood that after determining the real-time distance between the target life form and the target device, it can determine whether the target life form is approaching or moving away from the target device based on the real-time distance, thereby controlling the target device to perform corresponding actions.

[0071] For example, the target device can be a desk lamp, and the target life form can be a user. When the distance determines that the user is approaching the desk lamp, the desk lamp can be turned on automatically, and when the distance determines that the user is moving away from the desk lamp, the desk lamp can be turned off automatically. In this way, the user can avoid manually turning the desk lamp on and off, thereby improving the user's experience of using the desk lamp.

[0072] For example, the target device can be a cabinet air conditioner, and the target life form can be a user. When the cabinet air conditioner is in air supply mode, and based on distance judgment, when the user is approaching the cabinet air conditioner, the cabinet air conditioner can automatically lower the power level; when the user is moving away from the cabinet air conditioner, the cabinet air conditioner can automatically raise the power level. This avoids the user having to manually raise or lower the power level, thereby improving the user's experience of using the cabinet air conditioner. When the cabinet air conditioner is in heating mode, and based on distance judgment, when the user is approaching the cabinet air conditioner, the cabinet air conditioner can reduce the heating power or turn off the heating mode; when the user is moving away from the cabinet air conditioner, the cabinet air conditioner can maintain the heating mode, thereby improving the user's experience of using the cabinet air conditioner.

[0073] For example, the target device can be an electric heating device, and the target life form can be a user. When the distance determines that the user is close to the electric heating device, the electric heating device can reduce the heating power or turn off the heating mode. When the distance determines that the user is far away from the electric heating device, the electric heating device can maintain the heating mode.

[0074] It is understood that the target life form 106 can be a user or an animal, and the target device 102 can be a household appliance for user use, such as an electric heating device or other type of device that affects the safety of the target life form. It is understood that the specific content of the target device can be determined according to the actual application, and this application does not make specific limitations. For ease of description, the following embodiments are exemplified by the target device 102 being a device that affects the safety of the target life form.

[0075] In one embodiment, such as Figure 2 As shown, a distance determination method is provided, which can be applied to... Figure 1 The following steps are described using the distance determining device 104 as an example:

[0076] S202 controls the target device to generate a real-time electromagnetic field.

[0077] In this embodiment, the target life form is a conductor. Conductors can interact with magnetic fields. Therefore, based on the interaction between the real-time electromagnetic field generated by the target device and the target life form, it can be determined whether the target life form is close to the target device. Specifically, controlling the target device to generate a real-time electromagnetic field includes:

[0078] S11, determine the real-time transmission signal corresponding to the transmission frequency.

[0079] S12 controls the target device to generate a real-time transmission magnetic field corresponding to the real-time transmission signal.

[0080] Once the transmission frequency is determined, the signal can be transmitted at that frequency, and the transmitted signal is the real-time transmission signal. The transmission frequency can be a fixed frequency or a variable frequency. When the transmission frequency is variable, the sampling period and the number of samples need to be set, and the transmission frequency is less than the ratio of 1 to a first value. The first value is the ratio of the number of samples to the sampling period. For example, when f represents the variable transmission frequency, N represents the number of samples, and T represents the sampling period, and the first value is N / T, then f < 1 / (N / T).

[0081] S204, based on the real-time electromagnetic field, obtains the real-time voltage value corresponding to the real-time capacitance value formed by the target device and the target life form.

[0082] In this embodiment, when the target device generates a real-time electromagnetic field, since the target life form is a conductor, there will be an interaction between the target life form and the target device. Specifically, when the target life form approaches the target device, a real-time capacitance value will be formed between the target device and the target life form, so that the corresponding real-time voltage value can be obtained based on the real-time capacitance value.

[0083] S206, Based on the real-time voltage value, determine the real-time distance between the target life form and the target device.

[0084] In this embodiment, the closer the target life form is to the target device, the smaller the corresponding real-time voltage value. Therefore, the real-time distance between the target life form and the target device can be determined by the real-time voltage value, and then it can be determined whether the target life form is close to the target device. When it is determined that the target life form is close to the target device, the target device can be controlled to perform corresponding actions to avoid the target device from affecting the safety of the target life form.

[0085] In the aforementioned distance determination method, a real-time electromagnetic field is generated by controlling the target device, and a real-time voltage value corresponding to the real-time capacitance value formed by the target device and the target living organism is obtained based on the real-time electromagnetic field. Then, the real-time distance between the target living organism and the target device is determined based on the real-time voltage value. By the interaction between the conductor characteristics of the target living organism and the real-time electromagnetic field generated by the target device, it is determined whether the target living organism is close to the target device. Compared with the existing infrared detection methods, the method proposed in this application can detect whether the target living organism is close to the target device comprehensively and from multiple angles, thereby improving the detection accuracy.

[0086] exist Figure 2 In the illustrated embodiment, the implementation of S204 is specifically as follows: Figure 3 The diagram illustrates a process for obtaining the real-time voltage value corresponding to the real-time capacitance value formed by the target device and the target living organism. This method is applied to... Figure 1 The following steps are described using the distance determining device 104 as an example:

[0087] S302, based on the multiple capacitance changes formed by the target device and the target life form, determine the corresponding real-time capacitance value and the voltage value corresponding to the real-time capacitance value.

[0088] In this embodiment, when the target life form is not close to the target device, a calibrated voltage value is established between the target life form and the target device. As the target life form gradually approaches the target device, a corresponding capacitance change occurs between the target life form and the target device based on the calibrated voltage value. Therefore, after multiple capacitance changes are established between the target device and the target life form, the corresponding real-time capacitance value is the sum of the calibrated capacitance value and each capacitance change. For example, C0 represents the calibrated voltage value. △ C represents the change in capacitance, so the real-time capacitance value C = C0 + ΔC. The calibration voltage value is a pre-set voltage value, which can be measured in advance through experiments. Specifically, in the experiment, the voltage value formed between the living organism and the target device when the distance between them is greater than or equal to the first calibration distance can be determined as the calibration voltage value.

[0089] In this embodiment, the transmitted signal includes a current value, and each real-time capacitance value corresponds to a voltage value. Therefore, each voltage value is the ratio of the current value corresponding to the real-time transmitted signal to the first value. The first value is the product of the corresponding real-time capacitance value and the transmission frequency. For example, U represents the voltage value, C represents the real-time capacitance value, I represents the current value corresponding to the real-time transmitted signal, and f represents the transmission frequency. Then, the first value = C × f, and U = I / (C × f).

[0090] S304 obtains the real-time voltage value based on the preset sampling period, preset sampling quantity, and corresponding voltage value.

[0091] In this embodiment, the voltage values ​​corresponding to a preset number of samples can be sampled according to a preset sampling period, and the real-time voltage value can be obtained by averaging the preset number of voltage values. For example, if the preset sampling period is T and the preset number of samples is N, then N voltage values ​​are sampled, and the real-time voltage value can be obtained by averaging the N voltage values.

[0092] In summary, Figure 3 In the illustrated embodiment, by determining the corresponding real-time capacitance value and the voltage value corresponding to the real-time capacitance value based on the multiple capacitance changes formed between the target device and the target life form, and then obtaining the real-time voltage value based on the preset sampling period, preset sampling quantity and the corresponding voltage value, it is possible to obtain the real-time voltage value based on the capacitance changes formed between the target life form and the target device, thereby determining the real-time distance between the target life form and the target device based on the real-time voltage value.

[0093] Based on the above, the calibration distance is the distance between the target life form and the target device. Specifically, the real-time distance between the target life form and the target device is determined according to the real-time voltage value, including: when the real-time voltage value is less than the first calibration voltage value and the real-time voltage value is greater than or equal to the second calibration voltage value, the real-time distance between the target life form and the target device is determined to be within a first calibration range; wherein, the calibration distance includes the first calibration distance and the second calibration distance, the upper limit of the first calibration range is the first calibration distance, the lower limit of the first calibration range is the second calibration distance, and the second calibration distance is less than the first calibration distance. Therefore, by setting the first calibration range, it can be determined that the target life form has not yet approached the target device. Therefore, the target device can continue to work according to the previous mode. Wherein, when the target device is an electric heating device, the previous mode can be the heating mode.

[0094] Furthermore, when the real-time voltage value is less than the second calibration voltage value and the real-time voltage value is greater than or equal to the third calibration voltage value, the real-time distance between the target life form and the target device is determined to be within the second calibration range; wherein, the calibration distance also includes a third calibration distance, the upper limit of the second calibration range is the second calibration distance, the lower limit of the second calibration range is the third calibration distance, and the third calibration distance is less than the second calibration distance.

[0095] Furthermore, when the real-time voltage value is less than the third calibration voltage value and the real-time voltage value is greater than or equal to the fourth calibration voltage value, the real-time distance between the target life form and the target device is determined to be within the third calibration range; wherein, the calibration distance also includes the fourth calibration distance, the upper limit of the third calibration range is the third calibration distance, the lower limit of the third calibration range is the fourth calibration distance, and the fourth calibration distance is less than the third calibration distance.

[0096] Furthermore, when the real-time voltage value is less than the fourth calibration voltage value, the real-time distance between the target life form and the target device is determined to be within the fourth calibration range; wherein, the upper limit of the fourth calibration range is the fourth calibration distance.

[0097] Based on the above, it can be seen that the above is an illustrative example using the target device as an example. It can be understood that when the target life form is the target user, such as Figure 4 As shown, a state control method is provided, including:

[0098] S402, obtain the real-time distance between the target user and the target device.

[0099] In this embodiment, the real-time distance between the target user and the target device is the distance determined by the distance determination method, wherein, Figures 2 to 3 The target life form shown is the target user in this embodiment. The target device can be a home appliance, such as an electric heating device with a heating function. The home appliance can also be a cabinet air conditioner with a heating mode and a ventilation mode. The heating mode can provide hot air to the user, and the ventilation mode can provide cold air to the user. It is understood that the specific content of the target device can be set according to the actual application scenario, and this embodiment does not limit it.

[0100] S402 controls the operating status of the target device based on the real-time distance and the current operating mode of the target device.

[0101] In this embodiment, by obtaining the real-time distance between the target user and the target device, it is possible to determine whether the target user is close to the target device based on the real-time distance, and control the working state of the target device based on the current working mode of the target device to avoid affecting the safety of the target user during the operation of the target device, thereby increasing the protective function, preventing the target user from touching the target device and causing burns, improving the user's experience and safety when using the target device, and avoiding safety hazards.

[0102] It should be noted that the current working mode of the target device is different when the target device is different. For example, when the target device is the first target device, the first target device can be a cabinet air conditioner, and the current working mode of the cabinet air conditioner can be heating mode or ventilation mode; when the target device is the second target device, the second target device can be a heating device, for example, an electric kettle, and the current working mode of the heating device can be heating mode.

[0103] In one embodiment, taking the target device as the first target device and the target device's current operating mode as heating mode or ventilation mode as an example, the following is an illustrative description: Specifically, the calibrated distance is the distance between the target user and the target device. Based on the real-time distance and the target device's current operating mode, the operating state of the target device is controlled, including: when the real-time distance is within the first calibrated range and the target device's current operating mode is the first mode, maintaining the target device's first mode; wherein, the first mode is the heating mode.

[0104] The calibration distance includes a first calibration distance and a second calibration distance. The second calibration distance is smaller than the first calibration distance. The first calibration range is between the first calibration distance and the second calibration distance. Therefore, by setting the first calibration range, it can be determined that the target user has not yet approached the target device. Thus, the target device can be controlled to continue working according to the previous first mode.

[0105] When the real-time distance is within the first calibration range and the target device is currently operating in the second mode, the target device is controlled to operate at the first gear; where the first gear is the highest gear, and the second mode is the air supply mode. It can be understood that by setting the first calibration range, it can be determined that the target user has not yet approached the target device; therefore, the target device can be controlled to operate at the highest gear.

[0106] Furthermore, it may also include: when the real-time distance is within the second calibration range and the target device is currently operating in the first mode, reducing the heating power of the first mode; wherein, the current heating power may be reduced to half or the heating power may be reduced to a preset power; the calibration distance may also include a third calibration distance, the third calibration distance being less than the second calibration distance, and the second calibration range being between the second calibration distance and the third calibration distance.

[0107] When the real-time distance is within the second calibration range and the target device is currently operating in the second mode, the target device is controlled to the second speed setting; the second speed setting is lower than the first speed setting. Thus, by using the set second calibration range, it can be determined that the target user is approaching the target device; therefore, in air supply mode, the target device can be controlled to the second speed setting.

[0108] Furthermore, it may also include: when the real-time distance is within the third calibration range and the target device is currently operating in the first mode, turning off the first mode; wherein, the calibration distance also includes a fourth calibration distance, the fourth calibration distance is less than the third calibration distance, and the third calibration range is between the third calibration distance and the fourth calibration distance.

[0109] When the real-time distance is within the third calibration range and the target device is currently operating in the second mode, the control level of the target device is the third level; the third level is lower than the second level.

[0110] Furthermore, it may also include: when the real-time distance is within the fourth calibration range and the target device is currently operating in the first mode, controlling the target device to move away from the target user; wherein the fourth calibration range is between the target device and the fourth calibration distance.

[0111] The target device can be equipped with wheels at the bottom. When the real-time distance between the target user and the target device is detected to be within the fourth calibration range, the target device can be moved away from the target user by controlling the direction and speed of the wheels driven by the motor inside the target device.

[0112] When the real-time distance is within the fourth calibration range and the target device is currently operating in the second mode, the control position of the target device is the fourth position; the fourth position is the lowest position and is lower than the third position.

[0113] It is understood that when the target device is the first target device and the current working mode of the target device is the first mode, the above-mentioned methods of reducing the heating power of the target device in the first mode, turning off the first mode, and controlling the target device away from the target user are all safety modes of the target device. They are modes to avoid the target device from causing harm to the target user, so as to improve the safety and user experience of the target user when using the target device.

[0114] The target device can also be equipped with a voice broadcast function to remind users through voice playback; when the target device cannot recognize the above-set conditions, that is, when it cannot detect the target user within the set distance, it can resume the heating state, making it more intelligent.

[0115] It is understandable that when the target device is the first target device and the first target device is in air supply mode, the method of reducing the speed as the target user gradually approaches the target device, as described above, can improve the user experience of the target user using the target device.

[0116] In one embodiment, taking the target device as the second target device and the current operating mode of the target device as the third mode, specifically the heating mode, as an example, the preset distance is the distance between the target user and the target device. Based on the real-time distance and the current operating mode of the target device, the operating state of the target device is controlled, including:

[0117] When the real-time distance is within the first preset range and the target device is currently in the third working mode, the target device is maintained in the third mode; wherein, the third mode is the heating mode, the preset distance includes the first preset distance and the second preset distance, the second preset distance is less than the first preset distance, and the first preset range is between the first preset distance and the second preset distance.

[0118] Furthermore, it may also include: when the real-time distance is within a second preset range and the target device is currently operating in a third mode, reducing the heating power of the third mode; wherein the preset distance also includes a third preset distance, the third preset distance is less than the second preset distance, and the second preset range is between the second preset distance and the third preset distance.

[0119] Furthermore, it may also include: turning off the third mode when the real-time distance is within the third preset range and the target device is currently operating in the third mode; wherein the preset distance also includes a fourth preset distance, the fourth preset distance is less than the third preset distance, and the third preset range is between the third preset distance and the fourth preset distance.

[0120] Furthermore, it may also include: when the real-time distance is within a fourth preset range and the current operating mode of the target device is the third mode, controlling the target device to move away from the target user; wherein the fourth preset range is between the target device and the fourth preset distance.

[0121] The target device can be equipped with wheels at the bottom. When the real-time distance between the target user and the target device is detected to be within a fourth preset range, the target device can be moved away from the target user by controlling the direction and speed of the wheels driven by the motor inside the target device.

[0122] It is understandable that when the target device is a second target device, the second target device can be a heating device. If the heating device is in heating mode, there may be a risk of burns if the user gets close to the heating device. Therefore, based on the distance between the heating device and the user, the working state of the heating device can be controlled to prevent the user from being accidentally burned.

[0123] Combination Figure 4 The content shown is as follows: Figure 5 As shown, a target device is provided, which is a second target device. The second target device can be a heating device, which may include a power supply module, a microcontroller unit (MCU), and a transceiver antenna. The calibration capacitance value is the equivalent capacitance formed by the transceiver antenna and the ground. The transceiver antenna can be made of any kind of conductive metal material, such as a coil, a metal mesh, or a metal decorative strip. The fixed position of the transceiver antenna should be far away from the metal casing of the target device, the switching power supply, and other strong interference sources to avoid the strong interference sources affecting the detection results of whether the target user is close to the electric heating device, thereby improving the detection accuracy.

[0124] Specifically, the power supply module is used to power the MCU, enabling the MCU to transmit a real-time transmission signal with a transmission frequency of f to the transceiver antenna. When the target user approaches the heating device, the transceiver antenna and the ground form a real-time capacitance C. The MCU obtains the real-time voltage value U corresponding to the real-time capacitance C by sampling. Then, the MCU determines the real-time distance between the target user and the heating device based on the real-time voltage value U, and controls the working state of the heating device based on the real-time distance.

[0125] Combination Figures 2 to 4 The content shown is illustrated using the example of a target life form as the target user, a target device as the first target device, and the target device's current operating mode as the first mode, which is the heating mode. Figure 6 As shown, a flowchart illustrates a process for determining the real-time distance between a target device and a target user, and controlling the operating state of the target device based on the real-time distance and the current operating mode of the target device. The flowchart includes:

[0126] S602, determine the real-time transmission signal corresponding to the transmission frequency.

[0127] S604 controls the target device to generate a real-time electromagnetic field corresponding to the real-time transmitted signal.

[0128] S606, based on the multiple capacitance changes formed by the target device and the target user, determine the corresponding real-time capacitance value and the voltage value corresponding to the real-time capacitance value.

[0129] S608 obtains the real-time voltage value based on the preset sampling period, preset sampling quantity, and corresponding voltage value.

[0130] It is understandable that after obtaining the real-time voltage value, the real-time distance between the target user and the target device can be determined based on the relationship between the real-time voltage value and the calibrated voltage value. Based on this real-time distance, the target device is controlled to perform corresponding actions. The actions performed by the controlled target device differ depending on the real-time distance. The calibrated voltage value includes a first calibrated voltage value, a second calibrated voltage value, a third calibrated voltage value, and a fourth calibrated voltage value. The calibrated distance is the distance between the target user and the target device, and it includes a first calibrated distance, a second calibrated distance, a third calibrated distance, and a fourth calibrated distance. Specifically:

[0131] S610, when the real-time voltage value is less than the first calibrated voltage value and the real-time voltage value is greater than or equal to the second calibrated voltage value, the real-time distance between the target user and the target device is determined to be within the first calibrated range, and the first mode of the target device is maintained.

[0132] S612, when the real-time voltage value is less than the second calibration voltage value and the real-time voltage value is greater than or equal to the third calibration voltage value, the real-time distance between the target user and the target device is determined to be within the second calibration range, and the heating power of the first mode is reduced.

[0133] S614, when the real-time voltage value is less than the third calibration voltage value and the real-time voltage value is greater than or equal to the fourth calibration voltage value, determine that the real-time distance between the target user and the target device is within the third calibration range, and close the first mode.

[0134] S616, when the real-time voltage value is less than the fourth calibration voltage value, determines that the real-time distance between the target user and the target device is within the fourth calibration range, and controls the target device to move away from the target user.
