Description

Technical Field

[0001] The present invention relates to the field of wireless charging technology, and in particular to an intelligent wireless charging positioning method, device, equipment and storage medium. Background Art

[0002] When users first purchase and use a device to be charged, they often face a common problem - how to quickly and accurately find the best charging position for the device. When using it for the first time, users are usually unclear about which charging coils can provide the highest charging efficiency, which causes them to constantly try and adjust the position of the device until they find a relatively ideal charging point. This process is not only time-consuming and laborious, but also confusing and frustrating for users who are not familiar with technical operations.

[0003] In this context, users have to rely on their own experience and intuition to gradually explore the best charging position, which often means repeatedly moving the device and observing the charging indicator light or power changes to determine whether it is currently in the optimal charging state. Once a set of coils that perform well is found, users tend to remember these locations so that they can quickly place the device there for future use. However, this method is not only inefficient, but also requires repeating the same exploration process every time it is used, which greatly affects the user experience.

[0004] In order to solve the above problems, this study proposes an intelligent wireless charging positioning method, which can automatically identify the best charging position through the built-in positioning system and near-field communication technology when the user uses the device to be charged for the first time, and provide real-time guidance through the voice module to help users easily find and remember these positions. In addition, when the device is displaced during the charging process, the system can issue a reminder in time to guide the user to put the device back to the best charging point, thereby ensuring that the charging process is both efficient and convenient. This method not only simplifies the user's operating process and improves charging efficiency, but also enhances the intelligence level of the product, providing users with a more humane experience.

[0060] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0061] like Figure 1 As shown, Figure 1 It is a schematic diagram of the steps of an intelligent wireless charging positioning method in one embodiment of the present invention;

[0062] An embodiment of the present invention provides an intelligent wireless charging positioning method, comprising the following steps:

[0063] Step S1, before the optimal charging position is determined, when it is detected that there is a device to be charged near the target charging plate, the positioning system in the target charging plate is activated.

[0064] Specifically, before the optimal charging position is determined, when the presence of a device to be charged is detected near the target charging pad, the positioning system in the target charging pad is activated. This means that when the user places the device to be charged near the charging pad for the first time, the sensor inside the charging pad will immediately sense the presence of the device and then automatically start its built-in positioning system. This process is seamless and fast, and is designed to provide users with an instant optimized charging experience. For example, suppose a user has just purchased a new smartphone and tries to charge it with a matching wireless charger for the first time. When the phone approaches the charging pad, the proximity sensor on the charging pad detects the presence of the phone and immediately triggers the activation of the positioning system. At this point, the positioning system starts working and preliminarily determines which coils are the most suitable charging points by analyzing the signal strength between the different coils between the phone and the charging pad. At the same time, in order to more accurately determine the optimal charging position, the positioning system will also combine near-field communication technology to exchange data with the phone to obtain more information about the device model, battery status, etc., in order to make a more accurate judgment. On this basis, the system can provide users with specific placement guidance through the voice module, such as "Please move your phone slightly to the left until you hear a confirmation tone", to help users quickly find the best charging position and ensure an efficient and smooth charging process. This series of operations are completed with almost no user awareness, greatly simplifying the complexity of first-time use and improving the overall user experience.

[0065] Step S2: positioning the device to be charged by the positioning system through a preset near field communication technology to obtain the position of the device to be charged.

[0066] Specifically, the positioning system locates the device to be charged by using a preset near field communication technology to obtain the location of the device to be charged. This process is further implemented on the basis of activating the positioning system after the target charging plate detects the presence of the device to be charged nearby. Specifically, when the user places the device to be charged (such as a newly purchased smart phone) near the charging plate for the first time, the sensor of the charging plate first detects the presence of the device and activates the positioning system. Subsequently, the positioning system establishes a communication connection with the device to be charged using a preset near field communication technology (such as NFC). Through this connection, the charging plate can obtain the specific location information of the device, including the distance and direction of the device relative to each coil on the charging plate. This process involves complex signal processing algorithms for parsing the data sent from the device to be charged, and then accurately locating the location of the device. For example, assuming that the user places the mobile phone on the charging plate, but the position is not ideal, the positioning system will exchange data with the mobile phone through NFC technology, analyze the signal strength between the mobile phone and each coil on the charging plate, and thus calculate the exact location of the mobile phone. Based on this information, the system can determine which coils can provide the best charging effect and provide guidance to users through the voice module, such as "Please move your phone a little to the right until you hear a prompt tone." In this way, even if the user is using it for the first time, they can quickly and accurately find the best charging position to ensure the efficiency and stability of the charging process. The entire positioning process not only simplifies the user's operating steps, but also improves the charging efficiency, providing users with a more intelligent and convenient user experience.

[0067] Step S3, selectively activating the charging coil disposed in the target charging plate based on the position of the device to be charged, to obtain a selectively activated charging coil.

[0068] Specifically, the charging coils set in the target charging plate are selectively activated based on the position of the device to be charged to obtain the selectively activated charging coils. This process is performed after the position of the device to be charged is determined by the positioning system and the preset near field communication technology in the previous step. Specifically, when the user places the device to be charged (such as a newly purchased smart phone) on the charging plate for the first time, the sensor of the charging plate detects the presence of the device and activates the positioning system. The positioning system uses NFC technology to establish a communication connection with the device to be charged and obtains the specific location information of the device, including the distance and direction of the device relative to each coil on the charging plate. Once the location of the device is determined, the charging plate will selectively activate the charging coil closest to the device to be charged based on this location information. This is because different charging coils cover different areas, and only by activating those coils that can effectively couple with the device to be charged can the charging efficiency be maximized. For example, assuming that the user places the mobile phone in the upper left corner of the charging plate, the positioning system determines this through NFC technology and instructs the charging plate to selectively activate the charging coil located in the upper left corner instead of activating all coils. Doing so not only improves charging efficiency, but also reduces unnecessary energy loss. In addition, the process of selectively activating the charging coil is dynamic, that is, if the user accidentally moves the device during charging, causing the device's position to change, the charging plate will re-evaluate the new position of the device in real time and adjust the activated charging coils accordingly. For example, if the user accidentally moves the phone a little to the right during charging, the positioning system will detect the new position again and selectively activate the charging coil on the upper right to ensure the continued efficiency of the charging process. In this way, the charging plate can not only quickly and accurately find the best charging position for the device to be charged, but also automatically adjust the charging strategy when the device position changes to ensure the stability and efficiency of the charging process. This series of operations are completed automatically in the background, and the user does not need to perform additional operations, which greatly improves the user experience.

[0069] Step S4, real-time tracking of the device to be charged to obtain the changed position of the device to be charged, dynamically adjusting the selectively activated charging coil in the charging coil based on the changed position of the device to be charged to obtain the adjusted activated charging coil, and determining the position of the device to be charged in the adjusted activated charging coil based on the positioning system.

[0070] Specifically, the device to be charged is tracked in real time to obtain the changed position of the device to be charged, the selectively activated charging coil in the charging coil is dynamically adjusted based on the changed position of the device to be charged to obtain the adjusted activated charging coil, and the position of the device to be charged in the adjusted activated charging coil is determined based on the positioning system. This process is an important part of the intelligent wireless charging positioning method, which ensures the efficiency and stability of the charging process. Specifically, when the device to be charged is placed on the target charging plate, the positioning system will continuously monitor the position change of the device. Through the preset near-field communication technology (such as NFC or Bluetooth), the positioning system can obtain the precise location information of the device to be charged in real time. For example, assuming that a user places a smart phone on a smart wireless charging plate, the positioning system on the charging plate will continuously detect the position of the phone. If the user accidentally moves the phone during the charging process, causing the phone to deviate from the initial optimal charging position, the positioning system will immediately capture this change. At this time, the system will dynamically adjust the activation state of the charging coil based on the new position information, and select the charging coil that best suits the current device position for activation. This process is completed automatically without manual intervention by the user, thereby ensuring that the charging efficiency is not affected by changes in the device position. Furthermore, the positioning system will continue to track the device's location changes in real time to ensure that the activation status of the charging coil is always synchronized with the device's location. For example, if the user moves the phone again, the positioning system will update the device's location information again and adjust the activated charging coil accordingly. Through this dynamic adjustment mechanism, the system can always maintain the best charging status no matter how the device moves. In addition, the positioning system will also record this location information and the corresponding charging coil activation method in a preset database to provide data support for future optimization. In this way, the system can not only respond to changes in the device's location in real time, but also improve the overall charging efficiency and user experience through continuous learning and optimization.

[0071] Step S5, after the optimal charging position is determined, during the process of placing the device to be charged at the optimal charging position of the target charging plate, when it is detected that the device to be charged deviates from the optimal charging position, the user is given verbal guidance through the voice module of the target charging plate to place the device to be charged at the optimal charging position of the target charging plate.

[0072] Specifically, after the optimal charging position is determined, when the device to be charged is placed in the optimal charging position of the target charging plate, if it is detected that the device to be charged deviates from the optimal charging position, the user is given verbal guidance through the voice module of the target charging plate, so that the device to be charged is placed in the optimal charging position of the target charging plate. This process ensures that the user can always place the device in the optimal charging position during use, thereby maintaining the efficiency and stability of charging.

[0073] Specifically, when a user places a device to be charged (such as a newly purchased smartphone) on the charging pad for the first time, the sensor of the charging pad detects the presence of the device and activates the positioning system. The positioning system uses NFC technology to establish a communication connection with the device to be charged and obtain the specific location information of the device. Through a series of signal processing and algorithm calculations, the positioning system determines the optimal charging position of the device and selectively activates the charging coil closest to the position to ensure maximum charging efficiency. However, in actual use, users may accidentally move the device, causing the device to deviate from the optimal charging position. At this time, the positioning system of the charging pad will monitor the position change of the device in real time. For example, if the user moves the phone slightly to the right during charging, the positioning system will immediately detect this change and recalculate the deviation of the device from the optimal charging position through the built-in algorithm. Once it is found that the device has deviated from the optimal charging position, the charging pad will issue language guidance to the user through the voice module, such as "Please note that your phone has deviated from the optimal charging position. Please move it slightly to the left until you hear a confirmation tone." This language guidance not only helps users quickly correct the position of the device, but also ensures the continuity and efficiency of the charging process. For example, when the user moves the phone to the left to the best charging position according to the voice prompt, the positioning system will confirm again that the device has returned to the best charging position and send a confirmation tone through the voice module, such as "Your phone has been placed in the best charging position, and the charging efficiency is the highest." This confirmation tone lets the user know that the device has been placed correctly and can continue to use it with confidence. Through this real-time monitoring and language guidance mechanism, the charging plate can intelligently respond to subtle changes in the device's position, ensuring that the user can place the device in the best charging position under any circumstances. This process not only simplifies the user's operating steps, but also improves charging efficiency, providing users with a more intelligent and convenient user experience.

[0074] In a specific embodiment, it also includes:

[0075] Identify the device type of the device to be charged and the charging interface position of the target charging plate through a preset machine vision technology;

[0076] Recording the activation method of the charging coil based on the device type of the device to be charged;

[0077] The device type corresponding to the device to be charged, the charging interface position of the target charging plate and the activation method of the charging coil are stored in a preset database, and different device types, charging interface positions of the target charging plate and the activation methods of the charging coil are recorded; wherein, the information stored in the preset database is used to optimize the positioning system and the activation method of the charging coil.

[0078] Specifically, the device type of the device to be charged and the charging interface position of the target charging plate are identified through the preset machine vision technology; the activation method of the charging coil is recorded based on the device type of the device to be charged; the device type corresponding to the device to be charged, the charging interface position of the target charging plate and the activation method of the charging coil are stored in a preset database, and different device types, charging interface positions of the target charging plate and the activation method of the charging coil are recorded for optimizing the positioning system and the activation method of the charging coil. This process aims to improve the efficiency and user experience of wireless charging through intelligent technical means. Specifically, when a user places a device to be charged (such as a newly purchased smartphone) on the charging plate for the first time, the charging plate will identify the device through the preset machine vision technology. Machine vision technology is a method based on image processing and pattern recognition, which can capture the image of the device to be charged through a camera or other imaging device and analyze it. For example, when a user places a mobile phone on the charging plate, the camera on the charging plate will take a photo of the mobile phone and identify the brand, model and other information of the mobile phone through the built-in image processing algorithm. At the same time, machine vision technology will also identify the location of the charging interface on the charging plate, which includes multiple charging coils, each covering a different area. Once the type of device to be charged and the location of the charging interface are identified, the system will record the activation method of the charging coil based on this information. Different device types require different charging coil configurations to achieve the best charging effect. For example, a certain mobile phone is best suited to use the coil in the upper left corner of the charging plate, while another mobile phone is more suitable for using the coil in the lower right corner. The system will selectively activate the most suitable charging coil based on the device type and the location of the charging interface, and record this activation method. Next, the system will store the device type corresponding to the device to be charged, the charging interface location of the target charging plate, and the activation method of the charging coil in a preset database. This database is a centrally managed information library for storing various device types and their corresponding charging configuration information. For example, the following information will be recorded in the database: "Brand A mobile phone model X, the best charging position is the upper left corner of the charging plate, and the activation coils are numbered 1 and 2". In this way, when the user uses the same mobile phone to charge next time, the system can directly retrieve this information from the database and quickly activate the corresponding charging coil without re-identification and calculation. In addition, the system will also record different device types, charging port locations, and charging coil activation methods to optimize the positioning system and charging coil activation methods. By analyzing a large amount of data, the system can continuously improve its algorithms to improve recognition accuracy and charging efficiency. For example, the system will find that a certain brand of mobile phone has the highest charging efficiency when charged in a specific location, and thus recommend this location first in future use.At the same time, the system can also continuously optimize the activation method of the charging coil based on user feedback and actual usage to ensure that each charging can achieve the best effect. Through this series of intelligent operations, users can not only quickly find the best charging position when using wireless charging devices, but also enjoy an efficient and stable charging experience. For example, if a user often uses a certain mobile phone for charging, the system will automatically activate the best charging coil every time the user places the phone on the charging plate after the first recognition and recording of relevant information, and provide real-time guidance through the voice module, such as "Your phone has been placed in the best charging position and the charging efficiency is the highest." This process not only simplifies the user's operating steps, but also improves the charging efficiency, providing users with a more intelligent and convenient user experience. In short, through the preset machine vision technology, database management and algorithm optimization, this intelligent wireless charging system can significantly improve the user's charging experience and ensure that each charging can achieve the best effect.

Specifically, this process starts from the design stage of the charging board. First, multiple positioning sensors are arranged on the target charging plate, and the multiple positioning sensors are positioned. These positioning sensors include magnetic field strength measurement sensors and near field communication sensors. For example, assume that 16 positioning sensors are evenly distributed on a rectangular charging plate, of which 8 are magnetic field strength measurement sensors and the other 8 are near field communication sensors. The position layout of these sensors is carefully designed to ensure that the position of the device to be charged can be evenly and effectively detected on the entire charging plate. Next, the charging area grid of the target charging plate is divided based on each of the positioning sensors after the position layout to obtain a charging area grid. That is, the charging plate is divided into several small grid areas, each of which is covered by one or more positioning sensors. For example, the charging plate can be divided into a 4x4 grid, each of which is covered by a magnetic field strength measurement sensor and a near field communication sensor. In this way, each grid area can independently detect the existence of the device to be charged and its location information. Then, the charging area grid coordinates are assigned, and a charging positioning grid is constructed based on the charging area grid with the assigned coordinates. This means that a unique coordinate needs to be assigned to each grid area so that the specific position of the device to be charged can be accurately located in the subsequent positioning process. For example, the upper left corner of the charging plate can be set as the origin (0,0), the lower right corner can be set as (4,4), and the coordinate range of each grid area is an integer coordinate between (0,0) and (4,4). In this way, a complete charging positioning grid is constructed, and each grid area has a clear coordinate identification.Next, based on the preset near field communication technology, the electromagnetic interaction signal between the target charging plate and the device to be charged is collected, and the electromagnetic interaction signal is filtered to obtain an electromagnetic filter signal. When the user places the device to be charged (such as a newly purchased smart phone) on the charging plate, the near field communication sensor communicates with the device to collect the electromagnetic interaction signal between the two. These signals contain the location information of the device, but due to interference in the environment, the collected signals need to be filtered to remove noise and interference to obtain a clean electromagnetic filter signal. Then, the electromagnetic filter signal is phase detected and extracted by a preset phase detection algorithm to obtain an electromagnetic phase signal. The phase detection algorithm can accurately measure the phase difference of the electromagnetic signal, which is very critical for determining the specific location of the device. For example, assuming that the phase difference of the collected electromagnetic filter signal in a certain grid area is 30 degrees, and the phase difference in another grid area is 60 degrees, these phase information can be extracted by the phase detection algorithm for subsequent positioning calculations. Next, the electromagnetic intensity of the electromagnetic filter signal is calculated to obtain the electromagnetic signal intensity value. The electromagnetic signal strength reflects the degree of coupling between the device and the charging plate. The higher the strength, the closer the device is to the charging plate. By calculating the electromagnetic signal strength in each grid area, a strength distribution map can be obtained to further refine the location information of the device. For example, assuming that the electromagnetic signal strength measured in a certain grid area is 80%, and the strength measured in another grid area is 60%, this indicates that the device is closer to the previous grid area. Finally, through the charging positioning grid, the device to be charged is located based on the electromagnetic signal strength value and the electromagnetic phase signal to obtain the location of the device to be charged. Taking into account the electromagnetic signal strength and phase information, the specific location of the device to be charged on the charging plate can be accurately determined. For example, assuming that the electromagnetic signal strength of the device in the (2,2) grid area is the highest and the phase difference is the smallest, then it can be determined that the best charging position of the device is in the (2,2) grid area. The system will issue instructions to the user through the voice module, such as "Please move your phone slightly to the left to achieve the best charging position." Through this series of steps, the charging plate can intelligently identify and locate the position of the device to be charged, ensuring that the user can quickly find the best charging position when using it for the first time. For example, when a user places a mobile phone on the charging pad for the first time, the charging pad will automatically detect and locate the position of the mobile phone through the above process, selectively activate the best charging coil, and provide real-time guidance through the voice module to help users adjust the mobile phone to the best charging position. This process not only simplifies the user's operation steps, but also improves the charging efficiency, providing users with a more intelligent and convenient user experience. In short, through the preset near-field communication technology and charging positioning grid, this intelligent wireless charging system can accurately identify and locate the position of the device to be charged, ensuring that each charging can achieve the best effect.The application of this technology not only improves the user experience, but also demonstrates the huge potential of wireless charging technology in the direction of intelligence.

[0088] In a specific embodiment, the selectively activating the charging coil disposed in the target charging plate based on the position of the device to be charged to obtain the selectively activated charging coil includes:

[0089] The coordinates of the position of the device to be charged are converted by a three-dimensional space mapping algorithm to obtain the three-dimensional space coordinates of the device to be charged; wherein the three-dimensional space coordinates include the center point coordinates and the boundary coordinates;

[0091] By using a preset magnetic field coupling algorithm, the magnetic field coupling strength between each charging coil and the device to be charged is calculated based on the three-dimensional space coordinates and the charging coil layout information to obtain magnetic field coupling strength data;

[0092] Selectively screening and combining the charging coils based on the magnetic field coupling strength data to obtain a charging coil combination;

[0093] Performing power allocation calculation on each of the charging coils in the charging coil combination to obtain an activation power value; wherein the activation power value includes a high power value of the main charging coil and a low power value of the auxiliary charging coil;

[0094] Performing pulse width modulation control on the charging coil based on the activation power value to obtain an activation timing of the charging coil;

[0095] The charging coil combination is activated based on the activation timing of the charging coils to obtain selectively activated charging coils.

[0096] Specifically, the selective activation of the charging coils arranged in the target charging board based on the position of the device to be charged to obtain the selectively activated charging coils includes: performing coordinate conversion on the position of the device to be charged through a three-dimensional space mapping algorithm to obtain the three-dimensional space coordinates of the device to be charged; wherein the three-dimensional space coordinates include center point coordinates and boundary coordinates; performing layout analysis on the charging coils arranged in the target charging board to obtain charging coil layout information; wherein the charging coil layout information includes the number, position and distribution of the charging coils, and the charging coils include main charging coils and auxiliary charging coils; based on the three-dimensional space coordinates and the charging coils through a preset magnetic field coupling algorithm, The electric coil layout information calculates the magnetic field coupling strength between each of the charging coils and the device to be charged to obtain magnetic field coupling strength data; based on the magnetic field coupling strength data, the charging coils are selectively screened and combined to obtain a charging coil combination; power allocation calculation is performed on each of the charging coils in the charging coil combination to obtain an activation power value; wherein the activation power value includes a high power value of the main charging coil and a low power value of the auxiliary charging coil; pulse width modulation control is performed on the charging coil based on the activation power value to obtain the activation timing of the charging coil; the charging coil combination is activated based on the activation timing of the charging coil to obtain a selectively activated charging coil. Specifically, this process starts with determining the position of the device to be charged. First, the coordinates of the position of the device to be charged are transformed by a three-dimensional space mapping algorithm to obtain the three-dimensional space coordinates of the device to be charged. The three-dimensional space coordinates here include not only the center point coordinates of the device, but also the boundary coordinates of the device to ensure that the specific position of the device on the charging plate can be fully reflected. For example, suppose a user places a smartphone on a charging pad, and the positioning system determines that the center coordinates of the device are (2, 2, 0.5), and the boundary coordinates are (1.5, 1.5, 0.5) to (2.5, 2.5, 0.5). These coordinate information provide the basis for subsequent calculations and controls. Next, the layout analysis of the charging coils set in the target charging pad is performed to obtain the charging coil layout information. The charging coil layout information includes the number, position and distribution of the charging coils, which are pre-designed and installed. For example, suppose that 16 charging coils are set on the charging pad, distributed in a 4x4 grid, and the position and number of each coil are known. These charging coils include main charging coils and auxiliary charging coils. The main charging coils are responsible for providing most of the charging power, while the auxiliary charging coils are used to optimize the charging effect and cover the edge area. Then, the magnetic field coupling strength between each charging coil and the device to be charged is calculated based on the three-dimensional space coordinates and the charging coil layout information through a preset magnetic field coupling algorithm to obtain magnetic field coupling strength data.The magnetic field coupling algorithm calculates the coupling strength between each charging coil and the device by analyzing the distribution and interaction of the electromagnetic field. For example, suppose that the coupling strength between the No. 1 charging coil and the device is 80% by calculation, the coupling strength of the No. 2 charging coil is 70%, and so on, and finally a complete magnetic field coupling strength data table is obtained. Based on the magnetic field coupling strength data, the charging coils are selectively screened and combined to obtain a charging coil combination. This process aims to select a charging coil combination that can provide the best charging effect. For example, suppose that by analyzing the magnetic field coupling strength data, it is found that the coupling strength of the No. 1, No. 2 and No. 5 charging coils is the highest, and the system will select these three coils to form a charging coil combination. In this way, the efficiency and stability of the charging process can be ensured. The power allocation calculation is performed on each of the charging coils in the charging coil combination to obtain an activation power value. The activation power value here includes a high power value of the main charging coil and a low power value of the auxiliary charging coil. Due to the high coupling strength, the main charging coil will allocate higher power, while the auxiliary charging coil will allocate lower power to optimize the overall charging effect. For example, assuming that charging coil No. 1 is the main charging coil and the power value assigned is 8W, and charging coils No. 2 and No. 5 are auxiliary charging coils and the power values ​​assigned are 2W and 1.5W respectively. Based on the activation power value, pulse width modulation control is performed on the charging coil to obtain the activation timing of the charging coil. Pulse width modulation (PWM) control is a common power control technology that controls the power output of the charging coil by adjusting the width of the pulse. For example, assuming that the activation timing of charging coil No. 1 is 100% duty cycle, the activation timing of charging coil No. 2 is 50% duty cycle, and the activation timing of charging coil No. 5 is 30% duty cycle. In this way, the power output of each charging coil can be accurately controlled to ensure the stability and efficiency of the charging process. Finally, the charging coil combination is activated based on the activation timing of the charging coil to obtain a selectively activated charging coil. The system will activate the selected charging coils in sequence according to the calculated activation timing to ensure that the device to be charged can receive the best charging effect. For example, suppose that the system first activates charging coil No. 1, then activates charging coil No. 2 and No. 5 in sequence according to the above calculation results. During use, the system will provide real-time guidance through the voice module, such as "Your phone has been placed in the best charging position for the highest charging efficiency." Through this series of steps, the charging plate can intelligently select and activate the best combination of charging coils to ensure that each charging can achieve the best results. For example, when a user places a mobile phone on the charging plate for the first time, the system will automatically detect and locate the position of the mobile phone through the above process, selectively activate the best combination of charging coils, and provide real-time guidance through the voice module to help users adjust the mobile phone to the best charging position.This process not only simplifies the user's operation steps, but also improves charging efficiency, providing users with a more intelligent and convenient user experience. In short, through three-dimensional space mapping algorithm, magnetic field coupling algorithm, power distribution calculation and pulse width modulation control, this intelligent wireless charging system can accurately select and activate the best charging coil combination to ensure that each charging can achieve the best effect. The application of this technology not only improves the user experience, but also demonstrates the huge potential of wireless charging technology in the direction of intelligence.

[0098] Based on the electromagnetic signal strength value and the electromagnetic phase signal, the device to be charged is tracked in real time to obtain a tracking position of the device to be charged;

[0104] When the device to be charged reaches the adjustment activation charging coil, after the step of determining the position of the device to be charged at the adjustment activation charging coil based on the positioning system, the method further includes:

[0105] The optimal charging position is input and recorded in a voice module set in the device to be charged; wherein the voice module is used to remind the user that the device to be charged reaches the optimal charging position on the target charging plate.

[0106] Specifically, the real-time tracking of the device to be charged to obtain the changed position of the device to be charged, dynamically adjusting the selectively activated charging coil in the charging coil based on the changed position of the device to be charged to obtain the adjusted activated charging coil, and determining the position of the device to be charged in the adjusted activated charging coil based on the positioning system, includes: real-time tracking of the device to be charged based on the electromagnetic signal strength value and the electromagnetic phase signal to obtain the tracking position of the device to be charged; calculating the changed position of the device to be charged based on the position of the device to be charged and the tracking position of the device to be charged, and converting the changed position into a vector format to obtain a displacement vector; using a preset dynamic adjustment model to adjust the selectively activated charging coil in the charging coil based on the displacement vector of the device to be charged; and performing real-time magnetic field coupling efficiency calculation between the selectively activated charging coil and the device to be charged. Calculate and obtain the magnetic field coupling efficiency coefficient; when the magnetic field coupling efficiency coefficient reaches the preset efficiency threshold, the adjusted potential activated charging coil corresponding to the magnetic field coupling efficiency coefficient is determined to be the adjusted activated charging coil; wherein the adjusted activated charging coil is to achieve the maximum magnetic field coupling efficiency and the minimum energy loss; when the device to be charged reaches the adjusted activated charging coil, the position of the device to be charged at the adjusted activated charging coil is determined based on the positioning system; wherein the position is the optimal charging position; after the step of determining the position of the device to be charged at the adjusted activated charging coil based on the positioning system when the device to be charged reaches the adjusted activated charging coil, the optimal charging position is input and recorded into a voice module set in the device to be charged; wherein the voice module is used to remind the user that the device to be charged reaches the optimal charging position on the target charging plate. In order to better understand this complex step, its implementation process can be explained by a specific example. Assume that the user places a smart phone on the smart wireless charging plate for the first time. At this time, the positioning system on the charging plate will be activated immediately and start to track the position of the phone in real time. The positioning system can accurately determine the initial position of the phone by detecting the electromagnetic signal strength value and the electromagnetic phase signal. For example, when the user places the phone on the upper left corner of the charging plate, the positioning system will record this initial position. Next, the positioning system will continue to monitor the position changes of the phone. Suppose the user accidentally moves the phone slightly to the right during charging, the positioning system will capture this change in real time. Based on the initial position and new position of the phone, the system calculates the changed position of the phone, and converts this changed position into a vector format to obtain a displacement vector. For example, if the phone moves from the upper left corner to the middle position, the positioning system will calculate this displacement vector, indicating that the phone has moved a certain distance to the right. Then, the system uses a preset dynamic adjustment model to adjust the selectively activated charging coil in the charging coil based on the displacement vector of the phone.Specifically, the system will select the charging coil closest to the phone for activation based on the new position of the phone to ensure the highest charging efficiency. For example, if the phone moves a distance to the right, the system will select the charging coil on the right to activate instead of continuing to use the charging coil on the left. After selectively activating the charging coil, the system will perform real-time magnetic field coupling efficiency measurement to determine the coupling efficiency between the currently activated charging coil and the phone. The system will calculate the magnetic field coupling efficiency coefficient, which is an important indicator for measuring charging efficiency. If the magnetic field coupling efficiency coefficient reaches the preset efficiency threshold, the system will determine the current activated charging coil as the adjusted activated charging coil. This means that the current charging coil configuration has achieved the best magnetic field coupling efficiency and the minimum energy loss, ensuring the efficiency of the charging process. When the phone reaches the adjusted activated charging coil, the positioning system will reconfirm the location of the phone to ensure that the phone is in the best charging position. For example, if the system selects the charging coil on the right to activate, the positioning system will confirm whether the phone is indeed in the best charging area of ​​the right charging coil. Once it is confirmed that the phone has reached the best charging position, the system will input and record this location information in the voice module inside the phone. Finally, the voice module will remind the user that the phone has reached the best charging position. For example, when a user places a mobile phone on the charging plate and moves it to the optimal position, the phone will issue a voice prompt: "Your device has reached the optimal charging position. Please maintain the current position for the best charging effect." This prompt not only helps users confirm the location of the device, but also improves the user experience, ensuring that the charging process is both efficient and convenient. Through this series of steps, the intelligent wireless charging positioning system can not only track the position changes of the device in real time and dynamically adjust the activation status of the charging coil, but also provide real-time user guidance through the voice module to ensure that the device is always in the optimal charging position, thereby achieving an efficient and stable wireless charging experience.

[0107] In a specific embodiment, during the process of placing the device to be charged at the optimal charging position of the target charging plate, when it is detected that the device to be charged deviates from the optimal charging position, a voice module of the target charging plate is used to provide language guidance to the user so that the device to be charged is placed at the optimal charging position of the target charging plate, including:

[0108] During the process of adjusting and activating the charging coil to charge the device to be charged, detecting the electromagnetic signal strength value and the electromagnetic phase signal during the charging process to obtain electromagnetic signal detection data;

[0109] When the electromagnetic signal detection data indicates that the device to be charged deviates from the optimal charging position, the displacement vector of the device to be charged is coded and converted to obtain playable voice coding data;

[0110] Converting the playable voice coding data into a command to obtain a voice playing command;

[0111] Outputting a voice prompt to the user based on the voice playback instruction to guide the user to adjust the position of the device to be charged to reach the optimal charging position;

[0112] When the user adjusts the position of the device to be charged to reach the optimal charging position, the position of the device to be charged is monitored in real time. When the device to be charged reaches the optimal charging position, a voice module is used to output a voice prompt to the user that the device to be charged has reached the optimal charging position.

[0113] Specifically, during the process of placing the device to be charged at the optimal charging position of the target charging plate, when it is detected that the device to be charged deviates from the optimal charging position, the user is given language guidance through the voice module of the target charging plate, so that the device to be charged is placed at the optimal charging position of the target charging plate, including: during the process of adjusting and activating the charging coil to charge the device to be charged, the electromagnetic signal strength value and the electromagnetic phase signal during the charging process are detected to obtain electromagnetic signal detection data; when the electromagnetic signal detection data indicates that the device to be charged deviates from the optimal charging position, the displacement vector of the device to be charged is encoded and converted to obtain playable voice encoding data; the playable voice encoding data is converted into an instruction to obtain a voice playback instruction; based on the voice playback instruction, a voice prompt is output to the user to guide the user to adjust the position of the device to be charged to reach the optimal charging position; during the process of the user adjusting the position of the device to be charged to reach the optimal charging position, the position of the device to be charged is monitored in real time, and when the device to be charged reaches the optimal charging position, a voice prompt is output to the user through the voice module to prompt the user that the device to be charged has reached the optimal charging position. Specifically, this process starts with real-time monitoring during the charging process. During the process of adjusting and activating the charging coil to charge the device to be charged, the system will detect the electromagnetic signal strength value and the electromagnetic phase signal during the charging process to obtain electromagnetic signal detection data. This means that the charging plate will continuously monitor the electromagnetic signal strength and phase information during the charging process to understand the position change of the device in real time. For example, assuming that the user puts the mobile phone on the charging plate, the system will continuously detect the electromagnetic signal strength and phase signal between the mobile phone and the charging plate through the charging coil, and these data will be collected and analyzed in real time. When the electromagnetic signal detection data indicates that the device to be charged deviates from the optimal charging position, the system will start the corresponding adjustment mechanism. For example, assuming that the system detects that the mobile phone has moved 0.5 units to the right from the optimal charging position (2, 2, 0.5) and reached the new position (2.5, 2,0.5), the system will determine that the mobile phone has deviated from the optimal charging position based on the electromagnetic signal detection data. At this time, the system will start the next adjustment operation. Next, the displacement vector of the device to be charged is encoded and converted to obtain playable voice encoding data. The displacement vector represents the direction and distance of the device moving from the optimal charging position. For example, suppose the phone moves from (2, 2, 0.5) to (2.5, 2, 0.5), and the displacement vector is (0.5, 0, 0). The system converts this displacement vector into playable voice coding data so as to provide instructions to the user through the voice module. For example, the system converts the displacement vector (0.5, 0, 0) into voice coding data, which means "Please move your phone 0.5 units to the left". Then, the playable voice coding data is converted into instructions to obtain voice playback instructions.This process is to convert the coded data into specific voice playback instructions so that the voice module can execute it. For example, suppose that after the system converts the displacement vector (0.5, 0, 0) into voice coding data, the generated voice playback instruction is "Please move your mobile phone 0.5 units to the left". This instruction will be passed to the voice module and prepared for playback. Based on the voice playback instruction, a voice prompt is output to the user to guide the user to adjust the position of the device to be charged to reach the optimal charging position. The voice module will issue specific instructions to the user based on the received voice playback instruction. For example, when the user puts the mobile phone on the charging plate and the system detects that the mobile phone has deviated from the optimal charging position, the voice module will issue a prompt: "Please move your mobile phone 0.5 units to the left to reach the optimal charging position." The user can adjust the position of the mobile phone according to this prompt to return it to the optimal charging position. In the process of the user adjusting the position of the device to be charged to reach the optimal charging position, the system will monitor the position of the device to be charged in real time. When the device to be charged reaches the optimal charging position, a voice prompt is output to the user through the voice module to remind the user that the device to be charged has reached the optimal charging position. For example, if the user moves the phone 0.5 units to the left according to the voice prompt, the system will detect in real time that the phone has returned to the optimal charging position (2, 2, 0.5). At this time, the voice module will issue a confirmation prompt: "Your phone has been placed in the optimal charging position, and the charging efficiency is the highest." Through this series of steps, the charging plate can monitor the position change of the device in real time, and when the device deviates from the optimal charging position, it will issue specific adjustment instructions to the user through the voice module to help the user adjust the device back to the optimal charging position. This process not only simplifies the user's operation steps, but also improves the charging efficiency, ensuring that each charging can achieve the best effect. For example, when the user places the phone on the charging plate for the first time, the system will automatically detect and locate the position of the phone through the above process, selectively activate the best charging coil combination, and provide real-time guidance through the voice module to help the user adjust the phone to the optimal charging position. Even if the user accidentally moves the device during the charging process, the system will detect this change in real time and issue new instructions through the voice module, such as "Please move your phone 0.5 units to the left to reach the optimal charging position." When the user adjusts the position of the phone according to the prompt, the system will confirm again and issue a prompt: "Your phone has been placed in the best charging position, and the charging efficiency is the highest." In short, through real-time monitoring, voice guidance and dynamic adjustment, this intelligent wireless charging system can accurately respond to changes in the position of the device to ensure that each charging can achieve the best effect. The application of this technology not only improves the user experience, but also demonstrates the great potential of wireless charging technology in the direction of intelligence. Users can enjoy an efficient, stable and convenient charging experience during use without worrying about the decrease in charging efficiency due to the movement of the device.
