Detailed Description

In order that the above objects, features and advantages of the present disclosure may be more clearly understood, aspects of the present disclosure will be further described below. It should be noted that the embodiments and features of the embodiments of the present disclosure may be combined with each other without conflict.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure, but the present disclosure may be practiced in other ways than those described herein; it is to be understood that the embodiments disclosed in the specification are only a few embodiments of the present disclosure, and not all embodiments.

In an embodiment, as shown in fig. 1, a wireless charging method is provided, and this embodiment is illustrated by applying the method to a terminal, and it is to be understood that the method may also be applied to a server, and may also be applied to a system including the terminal and the server, and is implemented by interaction between the terminal and the server. In this embodiment, the method includes the steps of:

and S110, acquiring position coordinates of at least one powered device.

The powered device is a device requiring charging.

The powered device may include, but is not limited to, the following: the mobile terminal comprises a smart phone, a smart watch, a tablet computer, a notebook computer and other devices with an interactive interface, or portable devices such as a wireless earphone, an Augmented Reality (AR) device, a Virtual Reality (VR) device, a wireless keyboard, a wireless mouse and a remote controller, or fixed devices in the smart home such as an intelligent lock and an environment monitoring device.

The charging scene may include one charging device and a plurality of powered devices, and one charging device may sequentially support charging operations of the plurality of powered devices, or one charging device may simultaneously support charging operations of the plurality of powered devices at different electric energies.

The position coordinates of the powered device in the charging scene may be a three-dimensional coordinate system established in the charging scene, and the position coordinates of each powered device in the charging scene are the three-dimensional coordinates of the position of the powered device in the three-dimensional coordinate system.

And S120, determining the motion state of the powered device according to the position coordinates of the powered device.

The charging device may determine a motion state of the powered device according to the position coordinates of the device to be tested acquired within a period of time, where the motion state of the powered device may include a stationary state and a moving state.

When the charging device acquires the position coordinates of the powered device, the powered device needs to be positioned with high precision.

The high-precision positioning method in the present embodiment can adopt, but is not limited to: ultra-wideband (UWB), bluetooth, and the like. Such as UWB PDoA and bluetooth AoA, to locate the relative position of the powered device by the charging device.

The UWB is an ultra-wideband frequency spectrum (>500MHz) wireless communication technology with ultra-low power consumption, utilizes nanosecond-level non-sine wave ultra-short pulses to transmit data, and has the advantages of low system complexity (low cost), low power spectral density (low power consumption) of transmitted signals, insensitivity to channel fading, high positioning accuracy (centimeter level) and the like.

It should be noted that the high-precision positioning method in this embodiment may not require other positioning base stations/beacons.

The charging device may determine the motion state of the powered device by comparing a maximum displacement value of the powered device in a unit time with a preset displacement threshold. The unit time and the preset displacement threshold value can be selected according to actual conditions.

And S130, transmitting electromagnetic wave energy to the powered equipment according to the motion state of the powered equipment, so that the powered equipment converts the electromagnetic wave energy into electric energy for charging.

In a charging scene, the charging device can establish a connection channel with a plurality of powered devices in a communication connection mode, so that effective transmission of electromagnetic wave energy is guaranteed.

In this embodiment, the communication connection manner between the charging device and the powered device is not limited, and for example, the communication connection manner between the charging device and the powered device may include a wireless network, bluetooth, and the like.

In a charging scene, the distribution positions of a plurality of powered devices may not be regular, and the distance between each powered device and the charging device has a large difference, or there may be an obstacle between the powered device and the charging device. Therefore, the charging device needs to allocate corresponding electromagnetic wave energy to each powered device according to the position/shielding state of the different powered devices and the respective powered devices, thereby reducing the power consumption loss of the charging device.

In the wireless charging method provided by this embodiment, the position coordinates of at least one powered device in the charging scene are acquired, and the motion state of the powered device is determined according to the position coordinates of the powered device, so as to send electromagnetic wave energy to the at least one powered device, thereby implementing directional transmission of the electromagnetic wave energy. Therefore, the loss of electromagnetic wave energy is reduced, unnecessary electromagnetic radiation in a charging scene is reduced, and meanwhile, the charging efficiency of the powered device is effectively improved.

Fig. 2 is a schematic flowchart of another wireless charging method provided in the embodiment of the present disclosure. The embodiment is further expanded and optimized on the basis of the above embodiment, wherein one possible implementation manner of S120 is as follows:

and S1201, judging whether the motion state of the power receiving equipment is a static state or not according to the position coordinates of the power receiving equipment.

The motion state of the powered device may include a static state and a moving state, and when the powered device is in different motion states, the charging efficiency of the powered device may be affected, and therefore, the motion state of the powered device needs to be determined, so that accurate and efficient charging of the powered device is achieved.

Further, one possible implementation of S130 is as follows:

based on the description of the above embodiment, if the motion state of the power receiving apparatus is the stationary state, S1301 is performed, and if the motion state of the power receiving apparatus is the moving state, S1201 is continuously performed.

S1301, a signal characteristic parameter between the charging device and the powered device is obtained.

The signal characteristic parameter may be a signal strength, a multipath distribution, or the like between the charging device and the powered device.

Specifically, the charging device may send an induction signal to the powered device, and the powered device feeds back a response signal to the charging device when receiving the induction signal sent by the charging device, so that the charging device determines the signal characteristic parameter with the powered device.

And S1302, determining whether an obstacle exists between the charging device and the power receiving device according to the signal characteristic parameter.

When the signal characteristic parameter is lower than a preset parameter threshold, it may be considered that an obstacle exists between the charging device and the powered device.

Fig. 3 is a schematic illustration of a charging scenario. The charging device and the plurality of receiving point devices are included, the receiving point devices are irregularly distributed at different positions in a charging scene, and in fig. 3, an obstacle exists between one receiving point device and the charging device.

And S1303, transmitting the electromagnetic wave energy to the power receiving equipment according to the determination result.

When there is an obstacle between the charging device and the power receiving device, the energy of the electromagnetic wave transmitted to the power receiving device should be appropriately reduced, so as to reduce the energy loss of the charging device. When no obstacle exists between the charging device and the powered device, enough electromagnetic wave energy can be sent to the powered device, so that the powered device can complete device charging as efficiently as possible.

S1304, the charging efficiency fed back by the power receiving apparatus is received.

The power receiving equipment calculates the charging efficiency of the charging equipment according to the received electromagnetic wave energy sent by the charging equipment. The charging efficiency can be obtained according to the ratio of the charging power of the powered device to the charging power corresponding to the electromagnetic wave energy transmitted by the charging device.

Therefore, the charging efficiency is fed back to the charging equipment by the power receiving equipment, so that the charging equipment can master the charging condition of the power receiving equipment in time, and the reasonable distribution of the electromagnetic wave energy to the power receiving equipment is facilitated next time.

Fig. 4 is a schematic flowchart of another wireless charging method provided in the embodiment of the present disclosure. The present embodiment is further expanded and optimized based on the above embodiments, wherein one possible implementation manner of S1302 is as follows:

s13021 determines whether there is an obstacle between the charging apparatus and the power receiving apparatus, based on the signal characteristic parameter.

Further, one possible implementation manner of S1303 is as follows:

based on the description of the above embodiment, if there is no obstacle between the charging apparatus and the power receiving apparatus, S1303 is executed, and if there is an obstacle between the charging apparatus and the power receiving apparatus, S13021 is continuously executed.

S13031, determining a first electromagnetic wave energy to be sent to the powered device according to an identifier of the powered device and a preset power conversion table, where the preset power conversion table includes an association relationship between the identifier of the powered device and the distributed power; the first electromagnetic wave energy is transmitted to the powered device.

The preset power conversion table is transmission power that each powered device should distribute according to a power distribution algorithm in advance. The power allocation algorithm may be determined by referring to the distance between the powered device and the charging device and the priority level of the charging device.

The identifier of the powered device may be a name of the powered device or an identity number previously assigned to the powered device.

In the embodiment, the power distributed to the powered device is determined through the preset power conversion table, and the first electromagnetic wave energy is determined according to the power, so that the electromagnetic wave energy can be directionally and quantitatively transmitted to the powered device, the electromagnetic loss of the charging device is reduced, and the charging efficiency of the powered device is improved.

Based on the description of the above embodiment, optionally, the sending electromagnetic wave energy to the power receiving apparatus according to the determination result, includes:

if the obstacle is detected to exist between the charging equipment and the powered equipment, generating movement reminding information of the powered equipment, wherein the movement reminding information is used for indicating the mobile powered equipment;

and displaying the mobile reminding information.

When an obstacle is detected between the charging device and the power receiving device, in order to reduce the electromagnetic loss of the charging device, the power receiving device can be selected not to transmit electromagnetic wave energy.

The display of the mobile reminding information can timely inform a user that the current receiving equipment is difficult to charge, and the user is instructed to move the current receiving equipment, so that the current receiving equipment can be charged normally.

In addition, the display mode of the mobile reminding information can adopt but is not limited to the following modes: characters, voice, marker lights or other modes with the same effect can be achieved, and a user can know the charging condition of the powered device in time conveniently.

Based on the description of the above embodiments, when it is detected that an obstacle exists between the charging apparatus and the powered apparatus, it may also be determined whether to transmit electromagnetic wave energy to the powered apparatus according to a signal characteristic parameter between the charging apparatus and the powered apparatus.

In this embodiment, optionally, the sending electromagnetic wave energy to the power receiving device according to the determination result includes:

if the obstacle is detected to exist between the charging equipment and the powered equipment, whether a signal characteristic parameter between the charging equipment and the powered equipment is within a preset parameter range is judged;

if so, reducing the first electromagnetic wave energy to obtain second electromagnetic wave energy, wherein the first electromagnetic wave energy is determined according to the identifier of the powered device and a preset power conversion table;

the second electromagnetic wave energy is transmitted to the powered device.

When an obstacle is detected between the charging device and the powered device, and the signal characteristic parameter between the charging device and the powered device is within a preset parameter range, the powered device can be continuously charged.

Due to the existence of the obstacle between the charging device and the powered device, the first electromagnetic wave energy transmitted to the powered device needs to be reduced so as not to cause a large power loss of the charging device.

In addition, the charging device may continue to detect whether an obstacle still exists between the charging device and the power receiving device without performing a charging operation on the power receiving device when detecting that the obstacle exists between the charging device and the power receiving device, and transmit the first electromagnetic wave energy to the power receiving device when detecting that the obstacle does not exist between the charging device and the power receiving device. Thereby, the power receiving apparatus is enabled to be efficiently charged.

Based on the description of the above embodiment, optionally, the moving state of the power receiving apparatus is a moving state, and the transmitting electromagnetic wave energy to the power receiving apparatus according to the moving state of the power receiving apparatus includes:

judging whether the moving speed of the powered device is low or not according to the moving speed of the powered device in the moving process and a preset moving speed threshold;

if so, reducing the first electromagnetic wave energy to obtain third electromagnetic wave energy, wherein the first electromagnetic wave energy is determined according to the identifier of the powered device and a preset power conversion table;

the third electromagnetic energy transmission direction is adjusted based on the moving position of the power receiving apparatus, and the third electromagnetic energy is transmitted to the power receiving apparatus in accordance with the transmission direction.

The charging device may determine whether the powered device is at a low speed according to a maximum displacement value of the powered device per unit time, and determine that a moving speed of the powered device is at a low speed if the maximum displacement value of the powered device per unit time is smaller than a preset displacement threshold.

The unit time and the preset displacement threshold value can be selected according to actual conditions.

In this case, when the electromagnetic wave energy is transmitted to the powered device, the first electromagnetic wave energy transmitted to the powered device needs to be reduced to avoid a situation of large power loss of the charging device.

When the power receiving device is in a moving state, the transmission direction of the third electromagnetic energy transmitted by the charging device is also not fixed, and the transmission direction of the third electromagnetic energy transmitted by the charging device needs to correspond to the current position of the power receiving device. To ensure power loss of the charging apparatus, the third electromagnetic wave energy may be much smaller than the first electromagnetic wave energy.

According to the embodiment, when the power receiving equipment moves at a low speed, the power receiving equipment still carries out directional charging operation on the power receiving equipment, and the problem that the moving power receiving equipment is difficult to effectively charge can be effectively solved.

In this embodiment, optionally, after determining whether the moving speed of the power receiving apparatus is a low speed, the method of this embodiment further includes:

if not, generating charging reminding information of the powered device, wherein the charging reminding information is used for indicating that the charging of the powered device is stopped;

and displaying the charging reminding information.

Wherein, the display mode of the charging reminding information can adopt but is not limited to: characters, voice, marker lights or other modes with the same effect can be achieved.

When the moving speed of the powered device is detected to be high, normal charging operation on the powered device is difficult to perform at the moment, prompting is needed, and a user is informed that the powered device cannot perform the charging operation temporarily, so that the low-efficiency charging condition is restrained, and the charging state is improved.

Based on the above description of the embodiments, after the powered device completes charging, the powered device may further feed back the charging efficiency to the charging device, so that the charging device updates the next electromagnetic wave energy allocated to the powered device in real time according to the charging efficiency fed back by the powered device. The feedback charging efficiency can be used for electric quantity distribution and radio frequency control, and the electric quantity distribution and the radio frequency control are adjusted to achieve better charging efficiency, so that the charging efficiency of each powered device in a charging scene is effectively guaranteed.

The present embodiments also provide an illustration of a wireless charging system for a charging device. Wherein, wireless charging system can include: the device comprises a positioning module, a communication module, an interaction module, an electric quantity distribution module and a transmission control module.

The positioning module is used for receiving and sending control of positioning signals between the charging equipment and the powered equipment, receiving the positioning signals and analyzing signal characteristics.

The communication module is used for information transmission between various modules (an interaction module, a positioning module and an electric quantity distribution module) of the wireless charging system and between the powered devices.

The interactive module is an interactive interface between a user and the wireless charging system, and may include setting a power distribution mode, selecting a power distribution algorithm, registering specification parameters of the powered device, and the like, and other setting parameters that may be required. In addition, the user may be prompted for the current charging system operating state (e.g., identification of the device being charged, charging power, expected duration of full charge, etc.), a notification that the powered device is in a non-ideal charging scenario (e.g., the powered device is in a non-stationary state, the powered device is in a non-line-of-sight state, etc., and corresponding operating recommendations are given). The interactive information type includes but is not limited to text, voice, marker light, etc. The interaction module can carry out information transmission with the communication module and the electric quantity distribution module. The interaction module may be located inside the charging device or outside the charging device. When the interaction module is located outside the charging device, the communication module and the interaction module are required to communicate, and corresponding information is forwarded to the electric quantity distribution module.

The power distribution module is used for calculating the charging power according to the power distribution algorithm according to the positioning related information of the powered device, the parameters acquired by the communication module and the user setting information, and sending the charging power and the position information of the powered device to the transmission control module.

The emission control module is used for adjusting the emission unit according to the received control parameters to emit the electromagnetic wave energy.

Accordingly, the powered device may include a positioning module, a communication module, a radio frequency receiving module, and a power conversion module, and may or may not include an interaction module.

The wireless charging system provided by the embodiment acquires the state of the powered device through the high-precision positioning information, and distributes the electric quantity to the powered device by using the electric quantity distribution algorithm, so that the oriented charging is performed on one or more powered devices with the optimal charging efficiency. In particular, in the case of a low charging efficiency, such as a fast movement or a non-line-of-sight of the powered device, the user is prompted to adjust the powered device to a charging state with a better charging efficiency while taking measures to stop charging, reduce the amount of charging power, or reduce the priority of charging. Therefore, the effects of improving the overall charging efficiency of the remote wireless charging system and saving energy consumption are achieved.
