Referring now to the drawings, in which like numerals represent like elements, the principles of the present invention are illustrated as being implemented in a suitable computing environment. The following description is based on illustrated embodiments of the invention and should not be taken as limiting the invention with regard to other embodiments that are not detailed herein.
Referring to fig. 1, fig. 1 is a first flowchart illustrating a wireless charging method according to an embodiment of the present disclosure. The wireless charging method can be applied to wireless charging transmitting equipment. The flow of the wireless charging method may include:
in 101, a light detection signal is emitted outwards.
With the continuous development of technologies, more and more electronic devices are applied to wireless charging. Wireless charging refers to the transfer of electrical energy through a non-conductive substance. In practical applications, wireless charging generally refers to transferring electric energy across a certain spatial distance. At present, wireless charging technologies such as electromagnetic induction type and magnetic field resonance type are often adopted. However, in the related art, these wireless charging methods require that the wireless charging transmitting device and the wireless charging receiving device are close to each other. For example, in the electromagnetic induction type wireless charging mode, the wireless charging receiving device needs to be placed on a base of the wireless charging transmitting device for wireless charging.
In 101 of the present embodiment, the wireless charging transmitting device may transmit the light detection signal outwards. In one embodiment, the optical detection signal may be invisible light such as infrared light.
In some embodiments, the wireless charging transmitting device may be mounted on a ceiling or wall of a use environment (e.g., a room). As shown in fig. 2, the wireless charging transmission device 10 is installed on the ceiling of a room as an example. The wireless charging transmission device 10 may transmit the light detection signal outward. The optical detection signal is reflected multiple times and then received by the wireless charging receiving device 20 (such as a smart phone or a tablet computer). After receiving the optical detection signal, the wireless charging receiving device 20 may determine an incident angle of the optical detection signal, and then determine an emission angle of the optical response signal to be emitted according to the incident angle of the optical detection signal. Then, the wireless charging reception device 20 may transmit an optical response signal outward according to the determined transmission angle. The optical response signal may be received by the wireless charging transmission device 10 according to the principle that the optical path is reversible, as shown in fig. 3.
At 102, an optical response signal corresponding to the optical probe signal is received from the wireless charging receiving device.
For example, after the light detection signal is emitted outwards, the wireless charging transmitting device receives the light response signal from the wireless charging receiving device.
In 103, an angle of incidence of the optical response signal is determined, and a first target emission angle is determined based on the angle of incidence of the optical response signal.
For example, after receiving the optical response signal, the wireless charging and transmitting device may determine an incident angle of the optical response signal, and determine the first target transmission angle according to the incident angle of the optical response signal.
In 104, a first optical charging signal is transmitted according to a first target transmission angle to wirelessly charge a wireless charging receiving device.
For example, after determining the first target transmission angle, the wireless charging transmitting device may transmit the first optical charging signal outwards according to the first target transmission angle. For example, as shown in fig. 4, the wireless charging transmitting device 10 determines a first target transmitting angle according to the incident angle of the optical response signal, and transmits the first optical charging signal outwards according to the first target transmitting angle. Also, the first optical charging signal may be received by the wireless charging reception device 20 according to the principle that the optical path is reversible. After receiving the first optical charging signal, the wireless charging receiving device 20 may charge the battery with the first optical charging signal. For example, the first optical charging signal may be infrared light emitted from a laser diode, or the like. The wireless charging reception device may have a photovoltaic cell that can convert light energy of infrared light into electric energy and charge the battery using the converted electric energy.
It is understood that, in this embodiment, the wireless charging transmitting device may transmit the optical detection signal outwards, and after receiving the optical response signal of the optical detection signal from the wireless charging receiving device, the wireless charging transmitting device may determine an incident angle of the optical response signal, and determine the first target transmission angle according to the incident angle. Thereafter, the wireless charging transmitting device may transmit the optical charging signal according to the first target transmission angle to wirelessly charge the wireless charging receiving device. Since the present embodiment can utilize the optical signal to perform wireless charging, the distance between the wireless charging transmitting device and the wireless charging receiving device can be relatively long, that is, the present embodiment can implement long-distance wireless charging.
Referring to fig. 5, fig. 5 is a second flowchart illustrating a wireless charging method according to an embodiment of the present disclosure. The wireless charging method can be applied to wireless charging transmitting equipment. The flow of the wireless charging method may include:
in 201, the wireless charging transmitting device transmits a light detection signal outwards.
For example, as shown in fig. 6, the wireless charging transmitting device 10 may include an infrared light transmitting terminal 11 and an infrared light receiving terminal 12. The wireless charging transmitting device 10 may first transmit the infrared light detection signal to the outside through the infrared light transmitting terminal 11.
The wireless charging reception device 20 may also include an infrared light transmitting terminal 21 and an infrared light receiving terminal 22. The infrared light detection signal transmitted by the wireless charging transmitting device is reflected for multiple times and then received by the infrared light receiving end 22 of the wireless charging receiving device. After receiving the infrared light detection signal, the wireless charging receiving device may determine an incident angle of the infrared light detection signal, and then determine a transmission angle of the infrared light response signal to be transmitted according to the incident angle of the infrared light detection signal. Then, the wireless charging receiving device can transmit an infrared light response signal outwards through the infrared light transmitting terminal 21 according to the determined transmitting angle. According to the characteristics of optical path transmission, the transmission path of the infrared light response signal will be parallel to the infrared light detection signal, and the infrared light response signal can be received by the infrared light receiving end 12 of the wireless charging and transmitting device.
In some embodiments, the light receiving ends (e.g., infrared light receiving ends) of the wireless charging transmitting device and the wireless charging receiving device may include an angle sensor (e.g., a photoelectric angle sensor, etc.), which may be used to detect an incident angle of the light signal. Alternatively, the light receiving ends (e.g., infrared light receiving ends) of the wireless charging receiving device and the wireless charging transmitting device may be disposed in a cavity, which may be a rectangular parallelepiped cavity or a cubic cavity. As shown in FIG. 7, the cavity may have five solid faces, such as A, B, C, D, E, where faces A and B are the opposing sides of the cavity (left and right sides in FIG. 7), faces C and D are the opposing sides of the cavity (front and back sides in FIG. 7), and face E is the bottom of the cavity. The light receiving end may be disposed at the bottom surface E. A plurality of sensors may be provided on side A, B, C, D, E, and these sensors may detect light signals (e.g., infrared light). For example, when an optical signal enters from outside the cavity, the optical signal first hits a point a on the a surface, is reflected by the point a and received by the optical receiver provided on the bottom surface E, and the optical receiver is located at a point E on the bottom surface E. Then, the incident angle of the optical signal can be calculated according to the position relationship between the point a and the point e. For example, the incident angle of the optical signal may be the angle in space between the line segment ae and the bottom surface E.
In one embodiment, the light emitting ends of the wireless charging transmitting device and the wireless charging receiving device may include a rotatable structure, so that the light emitting ends can rotate within a certain angle range, so that the light emitting ends can emit light signals (such as light detection signals, light response signals, light charging signals, etc.) from different angles. For example, as shown in fig. 8, the light emitting end can be rotated from the position H to the position I or further from the position I to the position J by the rotation of the rotatable structure. As can be seen from fig. 8, the emission angles of the respective light signals emitted by the light emitting ends at the positions H, I and J may be different from each other, thereby realizing that the light emitting ends may emit the light signals outward from different angles.
In 202, the wireless charging transmitting device receives an optical response signal corresponding to the optical probe signal from the wireless charging receiving device.
For example, after the wireless charging receiving device transmits the infrared light response signal to the outside, the infrared light receiving end of the wireless charging transmitting device may receive the infrared light response signal transmitted by the wireless charging receiving device.
In 203, the wireless charging transmitting device determines an incident angle of the optical response signal and determines a first target transmitting angle according to the incident angle of the optical response signal.
For example, after receiving the infrared light response signal, the wireless charging and transmitting device may determine an incident angle of the infrared light response signal. Then, the wireless charging transmitting device can determine the first target transmitting angle according to the incident angle of the infrared light response signal.
In 204, the wireless charging transmitting device transmits a first optical charging signal according to the first target transmission angle to wirelessly charge the wireless charging receiving device.
For example, after determining the first target transmission angle, the wireless charging transmitting device may transmit the first infrared light charging signal according to the first target transmission angle. The first infrared light charging signal can be received by the wireless charging receiving device, so that the wireless charging receiving device is wirelessly charged. For example, the first infrared light charging signal may be infrared light emitted from a laser diode, or the like. The wireless charging reception device may have a photovoltaic cell that can convert light energy of infrared light into electric energy and charge the battery using the converted electric energy.
In other embodiments, in addition to infrared light as the optical charging signal, an invisible laser, for example, may be used as the optical charging signal.
In 205, the wireless charging transmitting device obtains the output power, and the charging power of the wireless charging receiving device.
For example, in the process of transmitting a first infrared light charging signal to the wireless charging receiving device according to the first target transmission angle to wirelessly charge the wireless charging receiving device, the wireless charging transmitting device may obtain its own output power and the charging power of the wireless charging receiving device.
In 206, the wireless charging transmitting device obtains the power loss ratio during wireless charging according to the output power and the charging power.
For example, after the output power of the wireless charging transmitting device and the charging power of the wireless charging receiving device are obtained, the wireless charging transmitting device may obtain the power loss ratio during wireless charging according to the output power and the charging power.
For example, the output power of the wireless charging transmitting device is 10W, while the charging power of the wireless charging receiving device is only 2W, and the power loss of the wireless charging is 8W, and the power loss of 8W can be considered to be mainly due to the attenuation loss of the first infrared light charging signal during the transmission in the air.
After the power loss ratio during wireless charging is obtained, the wireless charging transmitting device may detect whether the power loss ratio is greater than or equal to a preset threshold.
If the power loss proportion is smaller than the preset threshold value when the wireless charging is detected, the loss of the first infrared light charging signal in the air transmission process can be considered to be small, and at the moment, the wireless charging transmitting device can continue to transmit the first infrared light charging signal according to the first target transmitting angle so as to wirelessly charge the wireless charging receiving device.
If the power loss ratio during wireless charging is detected to be greater than or equal to the preset threshold, the loss of the first infrared light charging signal during air transmission may be considered to be large, and then the process may be entered into 207.
In 207, if it is detected that the power loss ratio is greater than or equal to the preset threshold, the wireless charging transmitting device reselects the transmitting angle of the optical charging signal.
For example, the output power of the wireless charging transmitting device is 10W, while the charging power of the wireless charging receiving device is only 2W, that is, the power loss of the wireless charging is 8W, and then the power loss ratio during the wireless charging is 80%. For example, the preset threshold is 65% or 70%. Then, since the power loss 80% during wireless charging is greater than the preset threshold, the power loss during wireless charging may be considered to be greater. This is believed to be primarily due to excessive energy loss from the optical charging signal during transmission. That is, when the infrared light charging signal is transmitted at the first target transmission angle, the transmission path of the infrared light charging signal is not a preferred path. In this case, the wireless charging transmission device may reselect the transmission angle of the infrared light charging signal.
For example, the wireless charging transmitting device may reselect one or more transmitting angles to transmit the infrared light detection signal outwards. If the wireless charging and transmitting equipment can receive the infrared light response signals corresponding to one or more paths of infrared light detection signals, the wireless charging and transmitting equipment can determine the incident angle of the corresponding infrared light response signals, and then determine the transmitting angle for transmitting the optical charging signals according to the incident angle, namely, the wireless charging and transmitting equipment reselects the transmitting angle for obtaining the optical charging signals.
In 208, the wireless charging transmitting device transmits a second optical charging signal outwards according to the reselected transmission angle to wirelessly charge the wireless charging receiving device, wherein the transmission angle of the second optical charging signal is different from the transmission angle of the first optical charging signal.
For example, after the emission angle of the optical charging signal is reselected, the wireless charging transmitting device may transmit a second infrared optical charging signal according to the reselected emission angle, so as to wirelessly charge the wireless charging receiving device. Wherein, the emission angle of the second infrared light charging signal is different from the emission angle of the first infrared light charging signal.
After the second infrared light charging signal is transmitted, the wireless charging transmitting device can also monitor whether the power loss proportion during wireless charging is larger than or equal to a preset threshold value. If so, the wireless charging transmitting device can reselect a different transmitting angle to transmit the optical charging signal again so as to wirelessly charge the wireless charging receiving device until the power loss ratio of the wireless charging receiving device wirelessly charged according to the optical charging signal transmitted by the selected transmitting angle is smaller than the preset threshold value. If the power loss ratios corresponding to the optical charging signals transmitted by the plurality of transmission angles selected by the wireless charging transmitting device are all larger than or equal to the preset threshold, the wireless charging transmitting device may select one transmission angle with the smallest power loss ratio to transmit the optical charging signal, so as to wirelessly charge the wireless charging receiving device.
In another embodiment, after the wireless charging transmitting device transmits the first infrared light charging signal according to the first target transmission angle, the following process may be performed instead of the processes 205 to 208 described above:
after a first optical charging signal is transmitted outwards, the wireless charging transmitting equipment monitors whether the first optical charging signal is blocked in the transmission process;
if the blocking occurs, the wireless charging transmitting equipment reselects the transmitting angle of the optical charging signal;
and the wireless charging transmitting equipment transmits a third optical charging signal outwards according to the reselected transmitting angle so as to wirelessly charge the wireless charging receiving equipment, wherein the transmitting angle of the third optical charging signal is different from that of the first optical charging signal.
For example, in the process of transmitting a first infrared light charging signal according to a first target transmission angle to wirelessly charge the wireless charging receiving device, the wireless charging transmitting device may monitor whether the first infrared light charging signal is blocked during transmission. That is, the wireless charging transmitting device may monitor whether the first infrared light charging signal is blocked by an object on a transmission path during transmission, so that the infrared light charging signal received by the wireless charging receiving device is intermittent.
If it is monitored that the first infrared light charging signal is not blocked in the transmission process, the transmission path of the first infrared light charging signal can be considered to be better, and the wireless charging transmitting device can continue to transmit the infrared light charging signal to the wireless charging receiving device according to the first target transmission angle.
If the first infrared light charging signal is monitored to be blocked in the transmission process, for example, the wireless charging transmitting device is in the process of communicating with the wireless charging receiving device, the wireless charging receiving device notifies the wireless charging transmitting device that the received optical charging signal is intermittent. Then, the transmission path of the first infrared light charging signal may be considered to be poor. In this case, the wireless charging transmitting device may reselect a transmission angle of the infrared light charging signal, and transmit a third infrared light charging signal according to the reselected transmission angle to the outside to wirelessly charge the wireless charging receiving device, where the transmission angle of the third infrared light charging signal is different from the transmission angle of the first infrared light charging signal.
In an embodiment, when the above-mentioned blocking occurs and the transmission angle of the optical charging signal is reselected, the wireless charging transmitting device may perform:
if the blocking happens, the wireless charging transmitting equipment counts the blocking times;
and when the blocking times are larger than or equal to a preset value, the wireless charging transmitting equipment reselects the transmitting angle of the optical charging signal.
For example, if the wireless charging transmitting device monitors that the first infrared charging signal is blocked in the transmission process, the wireless charging transmitting device may further count the blocking times, and reselect the transmitting angle of the infrared charging signal when the blocking times are detected to be greater than or equal to a preset value.
In one embodiment, the wireless charging transmitting device, when transmitting the light detection signal outwards, may perform:
the wireless charging and transmitting equipment acquires a historical transmitting angle, wherein the historical transmitting angle is the transmitting angle of the wireless charging and transmitting equipment when the wireless charging and transmitting equipment transmits a charging signal;
the wireless charging transmitting device transmits the light detection signal outwards according to a plurality of different angles, wherein the plurality of different angles comprise historical transmitting angles.
For example, when the wireless charging transmitting device transmits the optical charging signal to the outside, the transmitting angle of the optical charging signal may be recorded, so that the wireless charging transmitting device may obtain the historical transmitting angle of the optical charging signal.
Then, when the light detection signal needs to be emitted outwards for detecting the wireless charging receiving device, the wireless charging transmitting device may emit the light detection signal to a plurality of different angles, where the plurality of different angles include a historical emission angle acquired by the wireless charging transmitting device.
It will be appreciated that emitting the optical detection signal to historical emission angles of the optical charging signal may improve the efficiency of detecting the wireless charging receiving device. For example, in an office, a user generally sits on his or her seat, and the position where the user places a mobile phone (wireless charging receiving device) is generally fixed, so that the light detection signals are emitted according to the historical emission angles of the previous light charging signals, and the efficiency of detecting the mobile phone of the user by the wireless charging transmitting device can be improved.
In one embodiment, when the wireless charging transmitting device performs receiving of the optical response signal corresponding to the optical detection signal from the wireless charging receiving device, the following steps may be performed:
the wireless charging transmitting device receives an optical response signal corresponding to a target optical detection signal from the wireless charging receiving device, wherein the target optical detection signal is an optical detection signal received by the wireless charging receiving device at the earliest time.
For example, the wireless charging transmitting device transmits the optical detection signals outwards from a plurality of different angles, and the wireless charging receiving device can receive a plurality of paths of optical detection signals, so that the wireless charging receiving device can determine the earliest received optical detection signal as the target optical detection signal, determine the incident angle of the target optical detection signal, and determine a transmitting angle according to the incident angle of the target optical detection signal. Thereafter, the wireless charging reception device may emit the light response signal outward according to the emission angle. The wireless charging transmitting device can then receive the optical response signal.
It is understood that the transmission path of the optical detection signal received by the wireless charging reception device at the earliest time may be considered to be the shortest. The efficiency of wireless charging can be improved by adopting the shortest light path to carry out remote wireless charging.
In another embodiment, when the wireless charging transmitting device performs receiving of the optical response signal corresponding to the optical detection signal from the wireless charging receiving device, the following steps may be performed:
the wireless charging transmitting device receives an optical response signal corresponding to a target optical detection signal from the wireless charging receiving device, wherein the target optical detection signal is the strongest signal in the optical detection signals received by the wireless charging receiving device.
For example, the wireless charging transmitting device transmits the optical detection signals outwards from a plurality of different angles, and the wireless charging receiving device can receive the multiple paths of optical detection signals, so that the wireless charging receiving device can determine the path of optical detection signal with the strongest energy in the received multiple paths of optical detection signals as the target optical detection signal, acquire the incident angle of the target optical detection signal, and determine a transmitting angle according to the incident angle of the target optical detection signal. Thereafter, the wireless charging reception device may emit the light response signal outward according to the emission angle. The wireless charging transmitting device can then receive the optical response signal.
It can be understood that the optical path transmission path of the optical detection signal with the strongest energy may be regarded as the transmission path with the smallest energy loss, and the efficiency of wireless charging may also be improved by performing long-distance wireless charging using the optical path with the smallest energy loss.
Referring to fig. 9, fig. 9 is another schematic flow chart of a wireless charging method according to an embodiment of the present disclosure. The wireless charging method can be applied to a wireless charging receiving device. The flow of the wireless charging method may include:
in 301, an optical detection signal is received from a wireless charging transmitting device.
For example, after the wireless charging transmitting device transmits the light detection signal outwards, the light detection signal can be received by the wireless charging receiving device after multiple reflections. That is, the wireless charging reception device may receive the light detection signal out of the wireless charging transmission device.
In 302, an angle of incidence of the optical detection signal is determined.
For example, after receiving the optical detection signal, the wireless charging receiving device may determine an incident angle of the optical detection signal.
In 303, a second target emission angle is determined based on the angle of incidence of the optical detection signal.
In 304, a light response signal is emitted in accordance with the second target emission angle, the light response signal being responsive to the light detection signal.
For example, after the incident angle of the light detection signal is determined, the wireless charging receiving device may determine the second target emission angle according to the incident angle. Thereafter, the wireless charging reception device may emit an optical response signal outward according to the second target emission angle. Wherein the optical response signal is used for responding to an optical detection signal of the wireless charging transmitting device.
Referring to fig. 10 to 12, fig. 10 to 12 are schematic views of a wireless charging method according to an embodiment of the present disclosure.
Referring to fig. 10, for example, a wireless charging transmission device 10 is installed on a ceiling of a room. The wireless charging transmission device 10 can transmit and receive infrared light. The wireless charging transmitting device can emit infrared light to wirelessly charge the wireless charging receiving device for a long distance. Several reflecting means for reflecting infrared light may be installed at other locations in the room, such as walls, floors, etc., for example reflecting means 31, 32, 33, 34 may be included in the room.
For example, as shown in fig. 10, the wireless charging transmitting device 10 may include an infrared light transmitting terminal 11 and an infrared light receiving terminal 12. The wireless charging transmitting device 10 may first transmit the infrared light detection signal to the outside through the infrared light transmitting terminal 11. For example, the infrared light detection signal is reflected by the reflection devices 31, 34, and 33 in sequence, and then received by the infrared light receiving end 22 of the wireless charging and receiving device 20.
After receiving the infrared light detection signal, the wireless charge receiving device 20 may determine an incident angle of the infrared light detection signal. Then, the wireless charging reception device 20 may determine a transmission angle according to the incident angle of the infrared light detection signal, and the infrared light emitting terminal 21 of the wireless charging reception device 20 emits the infrared light response signal according to the transmission angle. As shown in fig. 11, the transmission path of the infrared response signal is parallel to the transmission path of the infrared detection signal according to the transmission characteristics of the optical path. The infrared light response signal may be received by the infrared light receiving end 12 of the wireless charging and transmitting device 10 after being reflected by the reflecting means 33, 34, 31 in sequence.
After receiving the infrared light response signal, the wireless charging and transmitting device 10 may determine an incident angle of the infrared light response signal, and determine the first target transmitting angle according to the incident angle of the infrared light response signal. After that, the wireless charging transmitting device 10 may transmit the infrared light charging signal at the first target transmission angle through its infrared light transmitting terminal 11. According to the transmission characteristics of the optical path, the transmission path of the infrared light charging signal is parallel to the infrared light response signal.
