detailed description

In order to make the objects, technical solutions and advantages of the present invention more clear, the present invention will be described below with reference to the accompanying drawings. The invention is further described in detail, and it is apparent that the described embodiments are only a part of the embodiments of the invention, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

The invention discloses a wireless charging control method. The flow of the first embodiment is as shown in FIG. 1 and includes:

In the wireless charging technology, the charging energy is radiated through the antenna, and in the charged charging area, multiple receiving ends (power receiving terminals) can be wirelessly charged simultaneously or sequentially. Whether wireless charging is performed sequentially or simultaneously, it is involved in judging and selecting a plurality of receiving ends (power receiving terminals) before charging or during charging. The present invention can also prioritize priorities by determining the priority of the powered terminals in the charging area. In the charging process, the powered terminals can be sequentially charged in descending order of priority, or simultaneously. The plurality of power receiving terminals are charged, but the charging efficiency of the power receiving terminal having the higher priority is preferentially increased in the order of priority from high to low.

In the step S100 of the above-described first embodiment, there are many methods for determining the charging priority of the power receiving terminal in the charging area. For example, the charging priority is determined according to a preset minimum power threshold and a power receiving information of the powered terminal in the charging area; the method is to preset a minimum threshold of the power, for example, 20% of the power, and which power receiving terminal has the first power information. Below 20% of the electricity, then who has the highest priority.

For example, the identification information of the powered terminal in the charging area is obtained, and the charging priority of the powered terminal in the charging area is determined according to the preset information according to the preset priority mapping table. The identification information here may be based on the MAC address or the IP address of the powered terminal, and the user pre-sets in the charging device, and may perform the power receiving terminal according to the MAC address, the IP address of the powered terminal, or the preference of the user. Priority setting, after only need to obtain the corresponding identification information of the powered terminal, The priority mapping table (identification information and corresponding priority) can be used to find the priority of the terminal.

After determining the charging priority of the powered terminal in the charging area, the power receiving terminal with the highest charging priority in the current charging area is selected from the terminal, and the terminal is used as the target terminal, and the subsequent methods are to improve the charging efficiency of the terminal.

The feedback information described in step S200 of the above embodiment 1 is used to determine a reference position of an antenna of the wireless charging device. The reference position is, for the target terminal, the antenna of the wireless charging device is located at the reference with respect to other positions. When charging, the charging efficiency is the highest.

According to the determination method of the reference position, it can be divided into the following two embodiments:

The flow of the wireless charging control method shown in the second embodiment is as shown in FIG. 2, and includes:

S220 compares the signal strength of each signal collection point, and finds the position of the signal acquisition point with the strongest signal as the reference position of the antenna;

In the above embodiment, the antenna of the wireless charging device is rotated according to a preset rule. The preset rule may be a preset antenna rotation track, or rotating in a clockwise or counterclockwise direction. Specifically, the wireless charging device used in this embodiment is a wireless charging router that can automatically rotate the antenna. According to the method of the present invention, the wireless charging efficiency of the power receiving terminal with high charging priority is prioritized. In the wireless charging process, for the power receiving terminal with high priority, during the charging process, the router detects the intensity of the charging energy received by the power receiving terminal through the WIFI (reflected by the signal strength), and feeds back to the router itself. When the router receives the feedback information through WIFI, it rotates the angle of the antenna through a small motor loaded on the antenna during the rotation. The signal strength of each preset signal collection point is fed back to the wireless charging router in real time. After such a step, the signal with the strongest signal can be obtained. The position of the signal collection point, the antenna of the router staying at this position can ensure the best charging angle during charging, so that the charging efficiency of the power receiving terminal with high charging priority is improved.

The motor that controls the rotation of the antenna can be controlled by the CPU of the router or by an external processor. The rotation of the antenna can be 360 degrees of rotation in the horizontal direction. We can equally divide the signal acquisition points by 360 degrees on the circumference. Of course, the more the number of collection points, the more accurate the reference position of the last positioning. Preferably, after obtaining the position of the signal acquisition point with the strongest signal in the horizontal direction, after the antenna rotates to the position of the strongest signal collection point, the antenna is rotated 180 degrees in the vertical direction to obtain the point of the best angle. The final point of this optimal angle can be considered the final reference position.

The third embodiment adopts a different reference position determining method than the second embodiment. Specifically, as shown in FIG. 3, the method includes:

S250 collects a signal strength of a current location of the target terminal;

S280 rotates the antenna to the reference position.

The general WiFi indoor positioning technology is mostly based on the IEEE802.Llb/G protocol wireless local area network (WLAN) signal strength localization technology. The basic principle of the signal strength based positioning technique is to estimate the distance between the signal receiver and the signal source based on the strength of the received signal. In this embodiment, the RSSI (received signal strength indicator) positioning algorithm can be classified into a positioning mechanism based on ranging by converting the signal strength into a distance and then solving the solution according to a specific geometric relationship. Therefore, the coordinates of the target terminal are obtained, and the method is more accurate. This method has mature algorithms in the industry, and will not be described here.

According to the fourth embodiment of the present invention, on the basis of the above-mentioned Embodiment 1, the steps are added:

S400 periodically collects feedback information of the target terminal, and when the feedback information of the target terminal changes, the process returns to step S200.

In this embodiment, the target terminal may be moved during the charging process. After the target terminal is displaced, the current position of the charging router antenna is not the optimal position, so it is necessary to reposition the new reference position to improve the charging efficiency. . Then, how to find that the target terminal is displaced. In this embodiment, after the antenna rotates to the reference position, the feedback information of the target terminal is periodically collected, and the feedback information changes according to the change of the displacement, such as the signal strength. After the target terminal moves, the optimal angle or position of the target terminal and the antenna bracket changes, and the signal strength also becomes weak. Therefore, we can also find the movement of the target terminal by the change of the signal strength. Preferably, when the change in signal strength exceeds a preset range, the reference position of the antenna is re-determined.

Embodiment 5 of the present invention, based on any of the above embodiments, adds steps:

In the embodiment, it is determined whether the priority of the newly added or reduced power receiving terminal is lower than the priority of the current target terminal in the charging region. It is necessary to rotate the antenna to re-determine the reference position of the antenna to ensure that the charging terminal with the highest charging priority in the charging area has the highest charging efficiency. Specifically, for example, a power receiving terminal is added. If the priority of the powered terminal is higher than the priority of the current target terminal, then the newly added power receiving terminal is set as the target terminal, because the target terminal occurs. If the change is made, then the reference position of the antenna needs to be re-determined to ensure that the new target terminal has the highest charging efficiency. Of course, if the priority of the newly added power receiving terminal is lower than the priority of the current target terminal, then no change is required. Until the power of the target terminal is full, the charging connection of the wireless charging device to the target terminal is disconnected, and then returning to step S100 to re-determine the target terminal in the remaining powered terminals. If it is to reduce the receiving terminal, Then, it is only necessary to judge whether the reduced power receiving terminal is the current target terminal. If yes, then it is necessary to return to step S100 to re-determine the target terminal. If not, then there is no need to change until the current target terminal is full of disconnected charging connection. Going back to step S100.

In the sixth embodiment of the present invention, based on any of the foregoing embodiments, step S150 is added. Specifically, as shown in FIG. 4, the method includes:

S150: Obtain an operating frequency of the target terminal for wireless charging, and adjust an operating frequency of the wireless charging device according to an operating frequency of the target terminal;

S150 in the above steps may be adjusted before the antenna is rotated, or may be adjusted after the antenna is rotated to the reference position. The present invention does not limit the order of execution of this step.

After obtaining the working frequency of the target terminal for wireless charging, the operating frequency of the charging module is adjusted accordingly (wireless charging is performed based on the magnetic resonance mode, and thus the resonance frequency of the magnetic resonance needs to be adjusted), so that the charging efficiency is performed during the wireless charging process. Improved. For example, the working frequency of the charging module can be adjusted according to the operating frequency of the target terminal during wireless charging, so that the operating frequency of the adjusted charging module is the same as the working frequency when the target terminal performs wireless charging.

Embodiment 7 of the wireless charging control method of the present invention, if the electronic devices in the charging area are: mobile phone A, mobile phone B, IPAD, and notebook computer. Let us take the example of wireless charging of the above devices in sequence (of course, it is also possible to charge a plurality of devices at the same time, but priority is given to improving the charging efficiency of devices with higher priority): First, the priority is determined by the amount of electricity. When the power of the mobile phone A is first less than the preset value m, then it is determined that the priority of the mobile phone A is the highest, then the mobile phone A starts charging; in this process, if the other device is lower than the preset value m, the other device is temporarily not available. Charging. When the mobile phone A is full, charge the remaining devices with a power lower than m; if the mobile phone B is lower than m at the beginning, Then, if the priority of the mobile phone B is the highest, the mobile phone B is charged first; of course, if the power of two devices is lower than the preset value m, and the two devices are simultaneously in the area of charging radiation, then The priority of the two devices is further determined based on the remaining power of the two devices, and the less the remaining power, the higher the priority. The mobile phone A with the highest priority is in the charging process. If the mobile device moves, the mobile process can also be found through the feedback information, because the received signal strength is reduced compared to the pre-moving signal strength during the moving process, so this It is then possible to control the rotating antenna until the signal strength of the feedback is greatest, and the point at which the signal strength of the feedback is strongest is the optimum position of the antenna (ie the new reference position).

Based on the same technical concept, the present invention further provides a wireless charging router, which uses the wireless charging control method of the present invention to charge an electronic device.

The wireless charging control module 30 can be integrated in the router, controlled by the router CPU, or can be a separate controller attached to the router. According to the present invention, when wireless charging is performed for a plurality of electronic devices, priority is given to charging efficiency of the electronic device with high priority, and the optimal position (ie, reference position) is obtained by rotating the antenna to charge the electronic device with high priority. The most efficient.
