Description
Technical Field
[0001] The present invention relates to the technical field of wireless charging, and particularly relates to a wireless charging calibration method, system, device, computer device and storage medium. Background Art
[0002] Infrared wireless charging technology is a truly long-distance wireless charging technology. The working distance can reach several meters or even farther. The energy has almost no loss during the transmission process, and different bands can be selected to charge multiple electronic devices simultaneously. At the same time, since infrared wireless charging does not generate electromagnetic waves, it also avoids the harm of electromagnetic pollution to the human body, and the working distance far exceeds the current contact or short-distance electromagnetic charging technology. The infrared light source used in infrared wireless charging technology is a non-illuminating light source mainly for generating infrared radiation. Infrared radiation is a certain range of electromagnetic radiation with a wavelength longer than that of red light, with a wavelength of 0.78 - 1000 μm, and is divided into three bands: near-infrared (designated IR-A, wavelength 0.78 - 1.4 μm), mid-infrared (IR-B, 1.4 - 3 μm), and far-infrared (IR-C, 3 - 1000 μm).
[0003] Due to different bands of infrared radiation, the spot intensity generated by the infrared light source is uneven. Therefore, when performing infrared charging, even when the infrared light source spot is aligned with the receiving device, it may not be at the maximum power position, resulting in a reduction in charging efficiency. The existing infrared charging only describes the general outline of the charging process and does not provide how to align the light source with the receiving end, or how to automatically calibrate to align the charging transmitting end with the charging receiving end to maximize the infrared charging efficiency, which is an urgent problem to be solved. Summary of the Invention
[0004] In view of this, embodiments of the present invention provide a wireless charging calibration method, system, device, computer device and storage medium to solve the problem that existing charging does not provide how to align the light source with the receiving end and does not automatically calibrate to align the charging transmitting end with the charging receiving end to maximize the charging efficiency.
[0005] In a first aspect, an embodiment of the present invention provides a wireless charging calibration method, which is applied to a charging transmitting end. The charging transmitting end includes an energy transmitting device. The wireless charging calibration method includes:
[0006] Transmitting energy from multiple emission points in a preset area to a charging receiving end, so that the charging receiving end responds to the charging operation;
[0007] Responding to receiving the charging power value corresponding to each emission point in the preset area sent by the charging receiving end;
[0008] Adjusting the position of the energy transmitting device based on the charging power value corresponding to each emission point in the preset area.
[0009] The wireless charging calibration method provided by the embodiment of the present invention sets a preset area at the charging transmitter, sets multiple emission points in the preset area to transmit energy to the charging receiver, and receives the charging power value corresponding to each emission point in the preset area sent by the charging receiver. Based on the charging power value corresponding to each emission point in the preset area, the position of the energy emission device is adjusted. Thus, it is possible to find the emission point corresponding to the maximum power value among the multiple charging power values corresponding to the multiple emission points to adjust the energy emission device, that is, to make the energy emission device in the position with the highest charging efficiency, and solve the problem that in the existing charging, there is no provision on how to align the light source with the receiver, and there is no automatic calibration to align the charging transmitter with the charging receiver to achieve the highest charging efficiency.
[0010] Combined with the first aspect, in an implementation manner, adjusting the position of the energy emission device based on the charging power value corresponding to the emission point in the preset area includes:
[0011] Screen out the first maximum power value among the multiple charging power values corresponding to the multiple emission points in the preset area;
[0012] Determine the corresponding first emission point according to the first maximum power value;
[0013] Adjust the position of the energy emission device based on the relationship between the first emission point and the emission points at the boundary of the preset area.
[0014] In an optional implementation manner, adjusting the position of the energy emission device according to the relationship between the first emission point and the emission points at the boundary of the preset area includes:
[0015] When the first emission point is an emission point at the boundary of the preset area, use the first emission point as the central emission point to determine a new preset area, continue to transmit energy to the charging receiver according to the multiple emission points in the new preset area until the first emission point corresponding to the first maximum power value is not a boundary point of the preset area, and adjust the position of the energy emission device to the first emission point that is not a boundary point of the preset area.
[0016] In an optional implementation manner, when the first emission point is not an emission point at the boundary of the preset area, adjust the position of the energy emission device to the first emission point.
[0017] The wireless charging calibration method provided by the embodiment of the present invention determines the corresponding first emission point through the maximum value of the first power. When the first emission point belongs to the emission point on the boundary of the preset area, at this time, the optical signal emitted by the energy emission device at the first emission point is not aligned with the center position of the charging receiver, and the charging power of the charging receiver is not the highest. Therefore, the first emission point is used as the center emission point to determine a new preset area, and multiple emission points in the new preset area continue to emit energy to the charging receiver until the first emission point corresponding to the maximum value of the first power is not the boundary point of the preset area. At this time, the power of the charging receiver corresponding to the first emission point is the largest, and the position of the energy emission device is adjusted to a position that is not the emission point on the boundary of the preset area; when the first emission point is not the emission point on the boundary of the preset area, the optical signal emitted by the energy emission device at the first emission point can be aligned with the center position of the charging receiver, so that the charging transmitter adjusts the position of the energy emission device to the first emission point, that is, the charging power of the charging receiver is the highest, achieving the purpose of automatic calibration and making the charging transmitter align with the charging receiver to maximize the charging efficiency.
[0018] In a second aspect, the embodiment of the present invention provides a wireless charging calibration method, which is applied to a charging receiver. The wireless charging calibration method includes:
[0019] Receiving the energy emitted by a plurality of emission points of the charging transmitter according to a preset area;
[0020] Generating a charging power value corresponding to each emission point according to the energy emitted by a plurality of emission points in the preset area;
[0021] Sending the charging power value corresponding to each emission point in the preset area to the charging transmitter, so that the charging transmitter adjusts the position of the energy emission device in the charging transmitter based on the charging power value corresponding to each emission point in the preset area.
[0022] The wireless charging calibration method provided by the embodiment of the present invention sets a preset area at the charging transmitter, sets a plurality of emission points in the preset area to emit energy to the charging receiver, and receives the charging power value corresponding to each emission point in the preset area sent by the charging receiver. Based on the charging power value corresponding to each emission point in the preset area, the charging transmitter adjusts the position of the energy emission device. Thus, it is possible to find the emission point corresponding to the maximum power value among the multiple charging power values corresponding to the multiple emission points, so that the charging transmitter adjusts the energy emission device, that is, the energy emission device is in the position with the highest charging efficiency, solving the problem that there is no method to align the light source with the receiver during existing charging, and there is no automatic calibration to make the charging transmitter align with the charging receiver to maximize the charging efficiency.
[0023] In combination with the second aspect, in one embodiment, enabling the charging transmitter to adjust the position of the energy transmitting device in the charging transmitter based on the charging power value corresponding to each transmitting point in the preset area includes:
[0024] Enabling the charging transmitter to screen out the first maximum power value among the charging power values corresponding to multiple transmitting points in the preset area, and enabling the charging transmitter to adjust the position of the energy transmitting device based on the relationship between the first transmitting point corresponding to the first maximum power value and the boundary point of the preset area.
[0025] In an alternative embodiment, enabling the charging transmitter to adjust the position of the energy transmitting device based on the relationship between the first transmitting point corresponding to the first maximum power value and the boundary point of the preset area includes:
[0026] When the first transmitting point is a boundary transmitting point of the preset area, enabling the charging transmitter to use the first transmitting point as the central transmitting point to determine a new preset area, and continue to receive the energy transmitted by multiple transmitting points according to the new preset area until the first transmitting point corresponding to the first maximum power value is no longer a boundary point of the preset area, and enabling the charging transmitter to adjust the position of the energy transmitting device towards the first transmitting point that is not a boundary point of the preset area;
[0027] When the first transmitting point is not a boundary transmitting point of the preset area, enabling the charging transmitter to adjust the position of the energy transmitting device towards the first transmitting point.
[0028] The wireless charging calibration method provided by the embodiments of the present invention determines the corresponding first transmitting point through the first maximum power value. When the first transmitting point belongs to the boundary transmitting point of the preset area, at this time, the optical signal emitted by the energy transmitting device at the first transmitting point is not aligned with the central position of the charging receiver, and the charging power of the charging receiver is not the highest. Therefore, the first transmitting point is used as the central transmitting point to determine a new preset area, and the energy is continuously transmitted to the charging receiver by multiple transmitting points according to the new preset area until the first transmitting point corresponding to the first maximum power value is no longer a boundary point of the preset area, and the position of the energy transmitting device is adjusted towards the position that is not a boundary transmitting point of the preset area, that is, to make the charging power of the charging receiver the highest, achieving the purpose of automatic calibration and making the charging transmitter align with the charging receiver to maximize the charging efficiency.

[0065] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
[0066] Unless otherwise defined, the technical terms or scientific terms used in this disclosure shall have the ordinary meanings as understood by those of ordinary skill in the art to which this disclosure pertains. The use of words such as "a", "an", or "the" in this disclosure does not denote a limitation of quantity, but rather indicates the presence of at least one. Words such as "comprising" or "including" mean that the elements or items appearing before this word cover the elements or items listed after this word and their equivalents, without excluding other elements or items.
[0067] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.
[0068] According to an embodiment of the present invention, an embodiment of a wireless charging calibration method is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and although the logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in a different order than here.
[0069] To address the technical problems mentioned in the background art, in this embodiment, a wireless charging calibration method is provided, which is applied to a charging transmitter. The charging transmitter includes an energy transmitting device, and the energy transmitting device can include, but is not limited to, an infrared light source transmitting device, etc. Figure 1 is a flowchart of the wireless charging calibration method according to an embodiment of the present invention, as Figure 1 shown, and this process includes the following steps:
[0070] Step S101: Transmit energy from multiple emission points in a preset area to the charging receiver, so that the charging receiver responds to the charging operation; specifically, the energy transmitting device includes, but is not limited to, an infrared emission light source. The infrared emission light source can emit one beam of light or multiple beams of light. The multiple beams of light can overlap at one position to enhance the energy per unit area, or can be tiled to increase the irradiation area, etc., which can be set according to specific circumstances and are not limited here; it can also have functions including, but not limited to, being able to adjust the size of the light energy area emitted by adjusting the aperture size, etc.
[0071] Exemplarily, as Figure 2 and Figure 5 shown, a preset area is set at the charging transmitter, and multiple emission points are set in the preset area to transmit energy to the charging receiver. For example, a preset area is set directly in front of the energy transmitting device of the charging transmitter, and the central emission point of the preset area is aligned with the center point of the charging receiver. Taking the energy transmitting device using an infrared emission light source as an example, the multiple emission points in the preset area can be divided into an N*N area according to the resolution of the infrared light source, so as to obtain N 2 emission points. Specifically, asFigure 3 As shown, the horizontal direction takes values of 1, 2, 3, …, N, and the vertical direction takes values of 1, 2, 3, …, N. A coordinate system is established for each combination of horizontal and vertical values, and the resulting coordinate points are emission points. For example: Figure 3 In [figure reference], the black boundary points are the coordinate points (1, 1), (2, 3), …, (N, N - 1), (N, N). Each coordinate point is an emission point, and there are N emission points within the N×N area. The infrared light source emission device emits optical signals to the charging receiving end according to the positions of the N emission points in the preset area, enabling the charging receiving end to perform photoelectric conversion after receiving the optical signals. 2 emission points, and the infrared light source emission device emits optical signals to the charging receiving end according to the positions of the N 2 emission points, enabling the charging receiving end to perform photoelectric conversion after receiving the optical signals.
[0072] Step S102: Respond to the charging power values corresponding to each emission point in the preset area sent by the charging receiving end;
[0073] Exemplarily, when an optical signal is emitted from each emission point, the charging receiving end receives the optical signal, and the charging receiving end performs photoelectric conversion to generate charging power. When the charging transmitting end emits optical signals to the charging receiving end at the N 2 emission points in the preset area, corresponding to the N 2 emission points, the charging receiving end will generate N 2 charging power values. At the same time, the charging receiving end sends the generated charging power values to the charging transmitting end.
[0074] Step S103: Adjust the position of the energy emission device based on the charging power values corresponding to each emission point in the preset area;
[0075] Exemplarily, as Figure 4 shown, the charging transmitting end further includes a collimating lens module, an automatic position calibration module, and a first main control module MCU. The collimating lens module is used to focus and collimate the optical signals emitted by the energy emission device, so that the spot size of the optical signals emitted by the energy emission device just covers the charging receiving end. Both the energy emission device and the automatic position calibration module are connected to the first main control module MCU. When the charging transmitting end emits optical signals to the charging receiving end at the N 2 emission points in the preset area, the charging receiving end performs photoelectric conversion to generate N 2 charging power values. At this time, the first main control module MCU controls the automatic position calibration module to adjust the position of the energy emission device based on the N 2 charging power values generated by the charging receiving end corresponding to the N 2 emission points. For example, adjust the position of the energy emission device according to the emission point corresponding to the maximum charging power value. Adjusting the position of the energy emission device includes, but is not limited to, moving the position of the energy emission device within the preset area or adjusting the angle.
[0076] The wireless charging calibration method provided by the embodiments of the present invention sets a preset area at the charging transmitter, sets a plurality of emission points in the preset area to emit energy to the charging receiver, and receives the charging power values corresponding to each emission point in the preset area sent by the charging receiver. Based on the charging power values corresponding to each emission point in the preset area, the position of the energy emission device is adjusted. Thus, it is possible to find the emission point corresponding to the maximum power value among the multiple charging power values corresponding to the multiple emission points to adjust the energy emission device, that is, to make the energy emission device in the position with the highest charging efficiency, solving the problem that in the existing charging, there is no provision on how to align the light source with the receiver, and there is no automatic calibration to align the charging transmitter with the charging receiver to achieve the highest charging efficiency.
[0077] In this embodiment, a wireless charging calibration method is provided, which can be used for the charging transmitter, etc. Figure 6 It is a flowchart of the wireless charging calibration method according to the embodiments of the present invention, as Figure 6 shown, and this process includes the following steps:
[0078] Step S201, emit energy to the charging receiver based on a plurality of emission points in the preset area, so that the charging receiver responds to the charging operation. For details, please refer to Figure 1 step S101 of the embodiment shown, which will not be elaborated here.
[0079] Step S202, in response to receiving the charging power values corresponding to each emission point in the preset area sent by the charging receiver. For details, please refer to Figure 1 step S102 of the embodiment shown, which will not be elaborated here.
[0080] Step S203, adjust the position of the energy emission device based on the charging power values corresponding to the emission points in the preset area.
[0081] Specifically, the above step S203 includes:
[0082] Step S2021, screen out the first maximum power value among the multiple charging power values corresponding to the multiple emission points in the preset area;
[0083] Exemplarily, the energy distribution in the area covered by the energy emitted by the charging transmitter is not necessarily uniform. Usually, the energy distribution per unit area is larger closer to the center of the area, and the energy distribution in the central area is the largest. Therefore, even if the charging receiver is completely covered by the area covered by the energy emitted by the charging transmitter, the energy received by the charging receiver is not necessarily the largest, that is, the energy reception efficiency is not necessarily the highest. Combining Figures 7 to 8 , taking the energy emission device using an infrared light source as an example, when the charging transmitter is in the preset area N 2When an emission point emits an infrared light signal to the charging receiving end, the emission range is from (0, 0) to (N, N), and each emission point corresponds to a coordinate point. The charging receiving end receives the light signals emitted by the infrared emission light source at each emission point. At this time, the charging receiving end will generate a charging power value. The positions where the light signals emitted by the infrared emission light source at different emission points irradiate on the charging receiving end are different. Therefore, corresponding to N 2 emission points will generate N 2 different charging powers. The charging receiving end transmits the N 2 charging powers to the charging transmitting end through Bluetooth, wireless WiFi or radio frequency signal transmission methods. The first main control module MCU of the charging transmitting end will screen out the maximum charging power value as the first power maximum value among the N 2 charging powers. For example, as Figure 7 shown, the charging power value corresponding to the emission point (1, 1) is 10 mV, and the charging power value corresponding to the emission point (1, 8) is 30 mV. The maximum charging power value of 30 mV corresponding to the emission point (1, 8) is used as the first power maximum value.
[0084] Step S2022: Determine the corresponding first emission point according to the first power maximum value;
[0085] Exemplarily, when the infrared light source emission device of the charging transmitting end emits light signals according to the preset area emission points, and screens out the first power maximum value among the charging power values corresponding to the N 2 emission points as 10 mV. At this time, it is queried that the first power maximum value of 30 mV is generated when the light source is emitted from the emission point (1, 8) to the charging receiving end. Therefore, the emission point (1, 8) is determined as the first emission point. As Figure 8 shown, if the first power maximum value is Pmax, then the corresponding first emission point is (Xmax, Ymax).
[0086] Step S2023: Adjust the position of the energy emission device based on the relationship between the first emission point and the emission points at the boundary of the preset area.
[0087] Specifically, the position of the energy emission device is adjusted according to whether the above-mentioned first emission point (Xmax, Ymax) is a boundary point of the preset N*N area. The position range scanned by the energy emission device each time is from (0, 0) to (N, N). When at least one of X or Y in the emission point (X, Y) is 1 or N, it can be determined that the emission point is at the boundary point position. When the first emission point belongs to the boundary emission point of the preset area, at this time, the optical signal emitted by the energy emission device at the first emission point is not aligned with the center position of the charging receiver, so the charging power of the charging receiver is not the highest. Taking the first emission point as the center emission point, a new preset area is determined, and multiple emission points continue to emit energy to the charging receiver according to the new preset area until the first emission point corresponding to the first power maximum value is not a boundary point of the preset area. At this time, the power of the charging receiver corresponding to the first emission point is the largest. When the first emission point is not a boundary emission point of the preset area, the optical signal emitted by the energy emission device at the first emission point can be aligned with the center position of the charging receiver, and the position of the charging transmitter to the energy emission device is adjusted to the first emission point, so that the charging power of the charging receiver is the highest. As Figure 9 shown, the automatic position calibration module can be implemented by a stepper motor, including a first stepper motor for adjusting the horizontal position and a second stepper motor for adjusting the vertical position. The first main control module MCU controls the first stepper motor and the second stepper motor of the automatic position calibration module to move the position or adjust the angle of the energy emission device.
[0088] Specifically, as Figure 10 shown, step S2023 includes:
[0089] Step S301, when it is determined that the first emission point is a boundary emission point of the preset area, taking the first emission point as the center emission point to determine a new preset area, and multiple emission points continue to emit energy to the charging receiver according to the new preset area until the first emission point corresponding to the first power maximum value is not a boundary point of the preset area, and adjusting the position of the energy emission device to the first emission point that is not a boundary point of the preset area;
[0090] Or,
[0091] Step S302, when it is determined that the first emission point is not a boundary emission point of the preset area, adjusting the position of the energy emission device to the first emission point.
[0092] For the wireless charging calibration method provided by the embodiments of the present invention, when the first emission point is a boundary emission point of the preset area, the position of the energy emission device is automatically calibrated by re-determining a new preset area, improving the charging efficiency; when the first emission point is not a boundary emission point of the preset area, adjusting the position of the energy emission device to the first emission point not only realizes the automatic calibration of the charging transmitter and the charging receiver, but also makes the charging power the highest.
[0093] In this embodiment, a wireless charging calibration method is provided, which can be used for a charging receiving end, etc. Figure 11 It is a flowchart of the wireless charging calibration method according to an embodiment of the present invention, as Figure 11 shown, and this process includes the following steps:
[0094] Step S401: Receive the energy emitted by a plurality of emission points in a preset area by the charging transmitting end;
[0095] Specifically, as Figure 12 shown, the charging receiving end is connected to the charging transmitting end through Bluetooth / WiFi / radio frequency communication. The charging receiving end includes a light receiving module and an energy storage device. When the charging transmitting end emits energy to the light receiving module of the charging receiving end according to a plurality of emission points in a preset area, the light receiving module converts light energy into electrical energy and stores the electrical energy in the energy storage device. For example, the light receiving module can be a solar panel.
[0096] Step S402: Generate a charging power value corresponding to each emission point according to the energy emitted by a plurality of emission points in a preset area;
[0097] Specifically, as Figure 12 shown, the charging receiving end further includes a second main control module MCU and a power detection module. Among them, the power detection module includes a charging current sampling circuit and a charging voltage sampling circuit. The second main control module MCU is respectively connected to the light receiving module, the charging current sampling circuit and the charging voltage sampling circuit; the light receiving module is respectively connected to the charging current sampling circuit and the charging voltage sampling circuit. When the light receiving module receives the light source energy emitted by the light receiving module of the charging receiving end, the second main control module MCU controls the charging current sampling circuit and the charging voltage sampling circuit to detect the current and voltage on the light receiving module, and obtains the charging power value according to the current and voltage, where the power is equal to the product of the current and the voltage. When the charging transmitting end emits light signals to the charging receiving end at N 2 emission points in a preset area, corresponding to the N 2 emission points, the charging receiving end will generate N 2 charging power values during photoelectric conversion.
[0098] Step S403: Send the charging power value corresponding to each emission point in the preset area to the charging transmitting end, so that the charging transmitting end adjusts the position of the energy emission device in the charging transmitting end based on the charging power value corresponding to each emission point in the preset area.
[0099] Specifically, when the charging transmitting end emits light signals to N 2 emission points in a preset area, the charging receiving end generates N 2 charging power values, and transmits the N 2Send N charging power values to the charging transmitter, so that the charging transmitter adjusts the position of the energy transmitting device based on the N charging power values corresponding to N emission points. 2 corresponding to N emission points 2 charging power values to adjust the position of the energy transmitting device.
[0100] Specifically, as Figure 13 shown, the above step S403 includes:
[0101] Step S4031, enabling the charging transmitter to screen out the first maximum power value among the charging power values corresponding to multiple emission points in the preset area;
[0102] Step S4032, enabling the charging transmitter to adjust the position of the energy transmitting device based on the relationship between the first emission point corresponding to the first maximum power value and the boundary point of the preset area.
[0103] Exemplarily, the energy distribution in the area covered by the light spot emitted by the charging transmitter is not necessarily uniform. Generally, the energy distribution per unit area is larger closer to the center of the area, and the energy distribution in the central area is the largest. Therefore, even if the area covered by the energy emitted by the charging transmitter covers the charging receiver entirely, the energy received by the charging receiver is not necessarily the largest, that is, the charging reception efficiency is not necessarily the highest. As Figure 3 shown, when the charging transmitter emits optical signals from N emission points in the preset area 2 to the charging receiver, the emission range is from (0,0) to (N,N), and each emission point corresponds to a coordinate point. When the charging receiver receives the optical signals emitted by the energy transmitting device at each emission point, at this time, the charging receiver will generate a charging power value after photoelectric conversion. The positions where the optical signals emitted by the energy transmitting device at different emission points irradiate on the charging receiver are different. Therefore, N 2 emission points will generate N 2 different charging powers. The charging receiver transmits the N 2 different charging powers to the charging transmitter through Bluetooth, wireless or radio frequency signal transmission methods. The first main control module MCU of the charging transmitter will screen out the maximum charging power value among the N 2 charging powers as the first maximum power value. For example, as Figure 7 shown, the charging power value corresponding to the emission point (1,1) is 10 mV, and the charging power value corresponding to the emission point (1,8) is 30 mV. The maximum charging power value of 30 mV corresponding to the emission point (1,8) is used as the first maximum power value. The first emission point is the emission point (1,8), so that the first main control module MCU of the charging transmitter controls the first stepping motor and the second stepping motor of the automatic position calibration module to move or adjust the angle of the energy transmitting device.
[0104] Specifically, the above step S4032 includes:
[0105] Step a1, when the first emission point is the emission point at the boundary of the preset area, the charging transmitter determines a new preset area with the first emission point as the central emission point, and continues to receive the energy emitted by multiple emission points according to the new preset area until the first emission point corresponding to the maximum first power is not the boundary point of the preset area, and then the charging transmitter adjusts the position of the energy emission device towards the first emission point that is not the boundary point of the preset area;
[0106] Step a2, when the first emission point is not the emission point at the boundary of the preset area, the charging transmitter adjusts the position of the energy emission device towards the first emission point.
[0107] Specifically, when the first emission point belongs to the emission point at the boundary of the preset area, at this time, the optical signal emitted by the energy emission device at the first emission point is not aligned with the central position of the charging receiver, so the charging power of the charging receiver is not the highest. The first emission point is used as the central emission point to determine a new preset area, and multiple emission points in the new preset area continue to emit energy to the charging receiver until the first emission point corresponding to the maximum first power is not the boundary point of the preset area, and then the charging transmitter adjusts the position of the energy emission device towards the first emission point that is not the boundary point of the preset area. When the first emission point is not the emission point at the boundary of the preset area, the optical signal emitted by the energy emission device at the first emission point can be aligned with the central position of the charging receiver, and the charging transmitter adjusts the position of the energy emission device towards the first emission point, so that the charging power of the charging receiver is the highest.
[0108] The present invention provides a wireless charging calibration system, as Figure 17 shown, including:
[0109] A charging receiver 1701, configured to execute any of the above wireless charging calibration methods applied to the charging receiver. For detailed content, refer to the description of the corresponding part in the above embodiments, which will not be elaborated here.
[0110] A charging transmitter 1702, which is communicatively connected to the charging receiver and is configured to execute any of the above wireless charging calibration methods applied to the charging transmitter.
[0111] Exemplarily, the communication connection may include wired communication and wireless communication, and the wireless communication includes but is not limited to Bluetooth or wireless communication. For detailed content, refer to the description of the corresponding part in the above embodiments, which will not be elaborated here.
[0112] As one or more specific application embodiments of the embodiments of the present invention, as Figure 14As shown in the figure, the wireless charging calibration system includes a charging transmitter and a charging receiver. The charging transmitter consists of a first main control module MCU, an automatic position calibration module, and an infrared light source emission device. The charging receiver consists of a second main control module MCU, a solar panel, and a power detection module. The charging transmitter communicates with the charging receiver via Bluetooth. The first main control module MCU of the charging transmitter is responsible for controlling the turning on and off of the automatic position calibration module and the infrared light source emission device, as well as communicating with the charging receiver, receiving the charging power of the charging receiver, and screening out the maximum power value among them. It determines the emission point Pmax(Xmax, Ymax) corresponding to the maximum power value, and moves the infrared light source emission device to the point Pmax(Xmax, Ymax) through the automatic position calibration module to complete the position calibration between the charging transmitter and the charging receiver. The second main control module MCU of the charging receiver is responsible for detecting the charging power value of the infrared light source emitted by each emission point on the solar panel. The second main control module MCU sends the charging power value of the infrared light source to the charging transmitter. After receiving the power data, the charging transmitter automatically screens out the maximum power value. The infrared light source spot emitted by the charging transmitter is within the preset area N*N, and there are N 2 emission points emitting infrared light sources, as Figure 5 shown. When the center point of the infrared light source spot emitted by the energy emission device of the charging transmitter is near the center point of the solar panel of the charging receiver, the charging power is the largest. As Figure 15 shown, the wireless charging calibration system can work according to the following process:
[0113] Step S501: The charging transmitter is powered on to turn on the infrared light source emission device and emit a light source spot;
[0114] Step S502: Basically align the light source with the solar panel according to whether the light source spot covers the solar panel;
[0115] Step S503: The charging transmitter emits infrared light signals at multiple emission points in the preset emission area N*N, scanning from the upper left corner to the lower right corner, that is, scanning from the emission point (1, 1) to the emission point (X, Y). The charging receiver records the charging power value P corresponding to each emission point. The second main control module MCU sends the charging power value P to the charging transmitter via Bluetooth. The charging transmitter determines the emission point (X, Y) corresponding to the charging power P value of each emission point;
[0116] Step S504: The first main control module MCU of the charging transmitter screens out the maximum power value Pmax and the corresponding emission point (Xmax, Ymax); As Figure 16A shown, the maximum power value Pmax = 10 millivolts (mv) selected for the first time, and the corresponding first emission point is (1, 1);
[0117] Step S505: If the first emission point belongs to the boundary point of the preset emission area, a new preset emission area is determined with the first emission point as the center, and the energy emitted by multiple emission points according to the new preset area is continuously received until the first emission point corresponding to the first maximum power is not the boundary point of the preset area.
[0118] Specifically, in combination with Figure 8 and Figure 16B , it is determined that the first emission point (1, 1) belongs to the boundary point of the preset emission area 8 * 8. Then, starting from the first emission point (1, 1) as the center position of the preset area, each emission point of the preset area 8 * 8 is scanned again. The charging power value P' corresponding to each emission point in the second group is recorded, and the second maximum power P'max = 30 millivolts (mv) is screened out again. The corresponding second emission point is (1, 8); as Figure 16C shown, at this time, the second emission point (1, 8) belongs to the boundary point of the preset emission area 8 * 8. Then, starting from the second emission point (1, 8) as the center position of the preset area, each emission point of the preset area 8 * 8 is scanned again. The charging power value P'' corresponding to each emission point in the third group is recorded, and the third maximum power P''max = 450 millivolts (mv) is screened out again. The corresponding third emission point is (5, 5). At this time, the third emission point (5, 5) does not belong to the boundary point of the preset emission area 8 * 8, and the third emission point is aligned with the center point of the solar panel.
[0119] Step 506: The first main control module MCU of the charging transmitter controls the automatic position calibration module to move the light source spot emitted by the infrared light source emission device to the third emission point (5, 5) corresponding to the third maximum power, and complete the automatic calibration.
[0120] The wireless charging calibration system provided by the embodiment of the present invention sets a charging transmitter and a charging receiver. The charging transmitter and the charging receiver are communicatively connected. The charging transmitter automatically adjusts the position of the infrared light source emission device according to the charging power of the solar panel on the charging receiver, so that the spot emitted by the infrared light source emission device is aligned with the center point of the solar panel, which can more conveniently and quickly complete the position calibration between the infrared light source emission device of the charging transmitter and the solar panel of the charging receiver, effectively solving the problem of position calibration of infrared wireless charging under medium and long distance conditions, and improving the charging power.
