Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Although wireless charging technology has been greatly developed, there are still many devices (such as mobile phones and tablet computers) that need to be charged, which cannot be charged by the wireless charging technology. For example, electromagnetic induction charging is the most common wireless charging solution at present, and the principle of electromagnetic induction charging is as follows: the wireless charging equipment is provided with a power transmission coil, and the equipment to be charged is provided with a power receiving coil; when alternating current with certain frequency exists in the power transmission coil, current is generated in the power receiving coil through electromagnetic induction, and therefore the purpose that electric energy is transmitted to the equipment to be charged from the wireless charging equipment is achieved. However, in practical applications, some manufacturers of devices to be charged do not configure a power receiving coil in the device to be charged, that is, the device to be charged cannot be charged by a wireless charging device adopting an electromagnetic induction charging technology. In practice, it is found that, assuming that the device a to be charged cannot be wirelessly charged by the wireless charging device, the wireless charging device will still wirelessly charge the device a to be charged placed within the chargeable range of the wireless charging device. For example, the wireless charging device still generates an alternating current with a certain frequency in the power transmission coil, and then generates a magnetic field in the air, but the device to be charged a cannot successfully generate a current under the action of the magnetic field, and therefore, the power of the wireless charging device is consumed. Therefore, the existing wireless charging mode is not beneficial to saving the electric energy of the wireless charging equipment.
The embodiment of the invention discloses a wireless charging method and wireless charging equipment, which are beneficial to saving electric energy of the wireless charging equipment. The details are described below.
Referring to fig. 1, fig. 1 is a schematic flowchart illustrating a wireless charging method according to an embodiment of the present invention. As shown in fig. 1, the wireless charging method may include portions S101 to S103. Wherein:
s101, the wireless charging equipment detects whether the equipment to be charged exists or not. If it is detected that there is a device to be charged, the S102 is performed. Optionally, if the wireless charging device detects that there is no device to be charged, the wireless charging device continues to detect whether there is a device to be charged.
In the embodiment of the present invention, the wireless charging device is a wireless charger or a wireless charging adapter, and the embodiment of the present invention is not limited.
In the embodiment of the present invention, the device to be charged may be a Mobile Terminal (Terminal) having a charging function, such as an Android Mobile phone, an iOS Mobile phone, a tablet computer, a Mobile Internet Device (MID), a Personal Digital Assistant (PDA), a video camera, and a camera. The Mobile terminal may also be referred to as a User Equipment (UE), a terminal, a wireless terminal or a Mobile Station (MS), and the like, which is not limited in the embodiments of the present invention.
In the embodiment of the invention, the device to be charged is a device, the distance between which and the wireless charging device is less than or equal to the preset distance. Wherein the preset distance may be greater than or equal to zero. When the preset distance is equal to zero, the device to be charged is a device with the distance from the wireless charging device equal to zero.
Optionally, the user terminal may detect whether there is a device whose distance from the wireless charging device is less than or equal to the preset distance by detecting the WiFi signal strength or the strength of another wireless signal of the device around the wireless charging device, that is, detect whether there is a device to be charged according to the WiFi signal or the strength of another wireless signal of the device around the wireless charging device.
Optionally, if the distance between the to-be-charged device and the wireless charging device is equal to zero, the specific implementation of the wireless charging device detecting whether there is the to-be-charged device may also be:
the method comprises the steps that the wireless charging equipment detects whether a pressure value applied to an equipment placing area of the wireless charging equipment is larger than a preset pressure value or not; if the pressure value received by the equipment placing area of the wireless charging equipment is larger than the preset pressure value, detecting that the equipment to be charged exists. Wherein the device placement area may be an area above the power transmitting coil.
Alternatively, it can be understood that the position where the distance from the wireless charging device is less than or equal to the preset distance is within the chargeable range of the wireless charging device. When a device is within the chargeable range of a wireless charging device, the device is likely to want to be charged. Therefore, by determining a device whose distance from the wireless charging device is less than or equal to a preset distance as a device to be charged, the device to be charged can be accurately determined.
S102, the wireless charging device detects whether the device to be charged is the target device.
In the embodiment of the invention, the target device is a device which can be successfully and wirelessly charged by the wireless charging device.
In the embodiment of the present invention, if the device to be charged is the target device, step S103 is executed. Optionally, if the device to be charged is not the target device, the process is ended. Or sending prompt information to the equipment to be charged, wherein the prompt information is used for prompting that the equipment to be charged cannot be wirelessly charged, or directly prompting that the equipment to be charged cannot be wirelessly charged by the wireless charging equipment, so that a user can timely find that the wireless charging equipment cannot wirelessly charge the equipment to be charged.
S103, the wireless charging device wirelessly charges the device to be charged.
In the embodiment of the present invention, the wireless charging device may wirelessly charge the device to be charged by using an electromagnetic induction type, a magnetic resonance type, a radio wave type, or an electric field coupling type, which is not limited in the embodiment of the present invention.
It can be seen that, by implementing the method described in fig. 1, after detecting that there is a device to be charged whose distance from the wireless charging device is less than or equal to the preset distance, the wireless charging device detects whether the device to be charged can be successfully wirelessly charged by the wireless charging device; and if the fact that the equipment to be charged can be successfully and wirelessly charged by the wireless charging equipment is detected, the equipment to be charged is wirelessly charged. The wireless charging device can be prevented from being wirelessly charged when the to-be-charged device cannot be successfully and wirelessly charged by the wireless charging device, and the wireless charging device can also perform wireless charging operation, so that the electric energy of the wireless charging device can be saved.
As an optional implementation, the specific implementation of S102 may include the following steps:
the wireless charging device acquires a first electric quantity value. The first electric quantity value is the current electric quantity value of the equipment to be charged. The wireless charging equipment wirelessly charges the to-be-charged equipment for a preset time period. The wireless charging device acquires a second electric quantity value. The second electric quantity value is the electric quantity value of the equipment to be charged after the equipment to be charged is wirelessly charged for a preset time period. The wireless charging device detects whether the second electric quantity value is greater than the first electric quantity value. And if the second electric quantity value is larger than the first electric quantity value, the equipment to be charged is the target equipment.
In this embodiment, the wireless charging device may send a request message to the device to be charged. And after receiving the request message, the equipment to be charged sends the current electric quantity value of the equipment to be charged to the wireless charging equipment.
In this embodiment, for example, if the wireless charging device detects that the device a to be charged is present, the wireless charging device detects a current electric quantity value (for example, 2000 ma) of the device a to be charged. After the electric quantity value of 2000 milliamperes is saved by the wireless charging equipment, the wireless charging equipment wirelessly charges the equipment to be charged for 5 seconds. The current charge value of device a to be charged (for example 2006 milliamps) is again detected after the end of 5 seconds. And if the wireless charging equipment detects that the 2006 milliampere is greater than 2000 milliampere, the equipment A to be charged is the target equipment.
As can be seen, by implementing this embodiment, the wireless charging device can accurately detect whether the device to be charged is the target device.
As an optional implementation, the specific implementation of S102 may include the following steps: the wireless charging equipment acquires the identifier of the equipment to be charged. And the wireless charging equipment judges whether the equipment to be charged is the target equipment or not according to the identifier of the equipment to be charged.
In this embodiment, the identifier of the device to be charged may be a model of the device to be charged, a brand of the device to be charged, or the like, and the embodiment of the present invention is not limited. By implementing the embodiment, the wireless charging device can accurately detect whether the device to be charged is the target device.
As an optional implementation manner, the specific implementation manner in which the wireless charging device determines whether the device to be charged is the target device according to the identifier of the device to be charged may include the following steps: the wireless charging equipment judges whether the identifier of the equipment to be charged exists in a first equipment identifier list pre-stored locally by the wireless charging equipment. The first device identification list comprises identifications of devices which can be successfully charged by the wireless charging device; and if the identifier of the equipment to be charged exists in the first equipment identifier list, the equipment to be charged is the target equipment.
For example, if the first device identifier list of the wireless charging device includes identifiers of device a and device B, the wireless charging device may wirelessly charge device a and device B. After the wireless charging device acquires the identifier of the device a to be charged, if the wireless charging device detects that the identifier of the device a to be charged is the same as the identifier of the device a or the identifier of the device B, the device a to be charged is a target device.
Whether the device to be charged is the target device can be quickly detected by storing the identifier of the device which can be successfully charged by the wireless charging device in the local database of the wireless charging device and judging whether the identifier of the device to be charged exists in the local database of the wireless charging device.
In this embodiment, the identification included in the first device identification list may be an identification of a device that can be successfully charged by the wireless charging device and that is allowed to be wirelessly charged by the wireless charging device. The device that is allowed to be wirelessly charged by the wireless charging device is the authorized device. Therefore, the wireless charging equipment does not wirelessly charge the unauthorized equipment to be charged which can be successfully charged by the wireless charging equipment, and the electric energy is saved.
As an optional implementation manner, the specific implementation manner in which the wireless charging device determines whether the device to be charged is the target device according to the identifier of the device to be charged may include the following steps: the wireless charging equipment sends the identifier of the equipment to be charged and the identifier of the wireless charging equipment to the server. The wireless charging equipment receives an indication message which is returned by the server and used for indicating whether the equipment to be charged is the target equipment. The indication message is obtained by the server according to the identifier of the equipment to be charged and the identifier of the wireless charging equipment; and if the indication message is used for indicating that the equipment to be charged is the target equipment, the equipment to be charged is the target equipment. And if the indication message is used for indicating that the equipment to be charged is not the target equipment, the equipment to be charged is not the target equipment.
In this embodiment, the server may be a server of any platform, and the embodiment of the present invention is not limited.
In this embodiment, after receiving the identifier of the device to be charged and the identifier of the wireless charging device, the server may search, via the internet, whether the wireless charging device can wirelessly charge the device to be charged according to the identifier of the device to be charged and the identifier of the wireless charging device. Or the server may maintain a correspondence list including correspondences between the wireless charging device and devices to be charged that can be charged by the wireless charging device, for example, the correspondence list may be as shown in table 1 below.
TABLE 1
| Identification of wireless charging device | Identification of device to be charged |
| Identification of wireless charging device A | Identification of device to be charged A |
| Identification of wireless charging device A | Identification of device to be charged B |
| Identification of wireless charging device B | Identification of device to be charged C |
The wireless charging device a in table 1 above can successfully and wirelessly charge the device to be charged a, the wireless charging device a can successfully and wirelessly charge the device to be charged B, and the wireless charging device B can successfully and wirelessly charge the device to be charged C. The method comprises the steps that a server receives an identifier of a wireless charging device A and an identifier of a device B to be charged, which are sent by the wireless charging device A, the server inquires whether a corresponding relation between the identifier of the wireless charging device A and the identifier of the device B to be charged exists in an upper table, and if the corresponding relation between the identifier of the wireless charging device A and the identifier of the device B to be charged exists in the upper table, an indication message for indicating that the device to be charged is a target device is returned to the wireless charging device; if the corresponding relation between the identifier of the wireless charging device A and the identifier of the device B to be charged does not exist in the upper table, returning an indication message for indicating that the device to be charged is not the target device to the wireless charging device.
In practical applications, the identifiers of the devices that can be successfully charged by the wireless charging device and are stored in the local database of the wireless charging device may not be comprehensive, and if the identifiers of the devices that can be successfully charged by the wireless charging device and are stored in the local database of the wireless charging device are used to detect whether the device to be charged is the target device, the detection result may be inaccurate. In the implementation of the embodiment, the server may update the stored correspondence between the wireless charging device and the device to be charged, which can be charged by the wireless charging device, at any time, so that the server has a more comprehensive identifier of the device to be charged, which can be charged by the wireless charging device, or the server may also query from another website whether the wireless charging device can successfully wirelessly charge the device to be charged, so as to more accurately determine whether the device to be charged is the target device.
As an optional implementation, the specific implementation of S102 may include the following steps: the wireless charging device sends a query request to the device to be charged. The query request includes an identifier of the wireless charging device, the query request is used for requesting the device to be charged to search whether the identifier of the wireless charging device exists in a second device identifier list pre-stored locally in the device to be charged, and the second device identifier list includes identifiers of devices capable of charging the device to be charged. The wireless charging equipment receives indication information returned by the equipment to be charged according to the search result; and if the indication message is used for indicating that the identifier of the wireless charging device exists in the second device identifier list, the device to be charged is the target device.
In this embodiment, for example, if the second device identifier list of the device a to be charged includes identifiers of the device a and the device B, the device a and the device B may wirelessly charge the device a to be charged. After the wireless charging device a sends the identifier of the wireless charging device a to the device to be charged a, if the device to be charged a detects that the identifier of the wireless charging device a is the same as the identifier of the device a or the identifier of the device B, the device to be charged a sends, to the wireless charging device a, indication information for indicating that the identifier of the wireless charging device a exists in the second device identifier list. If the to-be-charged device a detects that the identifier of the wireless charging device a is different from the identifiers of the device a and the device B, the to-be-charged device a sends, to the wireless charging device a, indication information for indicating that the identifier of the wireless charging device a does not exist in the second device identifier list. Therefore, whether the device to be charged is the target device or not can be accurately detected by implementing the embodiment.
As an alternative implementation, the specific implementation of S102 may also include the following steps: the wireless charging equipment acquires the identifier of the equipment to be charged. The wireless charging equipment judges whether the identifier of the equipment to be charged exists in a first equipment identifier list pre-stored locally by the wireless charging equipment. The first device identification list comprises identifications of devices which can be successfully charged by the wireless charging device; and if the identifier of the equipment to be charged exists in the first equipment identifier list, the equipment to be charged is the target equipment. If the identifier of the device to be charged does not exist in the first device identifier list, the wireless charging device acquires a first electric quantity value. The first electric quantity value is the current electric quantity value of the equipment to be charged. The wireless charging equipment wirelessly charges the to-be-charged equipment for a preset time period. The wireless charging device acquires a second electric quantity value. The second electric quantity value is the electric quantity value of the equipment to be charged after the equipment to be charged is wirelessly charged for a preset time period. The wireless charging device detects whether the second electric quantity value is greater than the first electric quantity value. And if the second electric quantity value is larger than the first electric quantity value, the equipment to be charged is the target equipment.
In practical applications, the identifiers of the devices that can be successfully charged by the wireless charging device and are stored in the local database of the wireless charging device may not be comprehensive, and if the identifiers of the devices that can be successfully charged by the wireless charging device and are stored in the local database of the wireless charging device are used to detect whether the device to be charged is the target device, the detection result may be inaccurate. By implementing the embodiment, when it is detected that the identifier of the device to be charged does not exist in the first device identifier list, the wireless charging device continues to detect whether the device to be charged is the target device in another way, so that whether the device to be charged is the target device can be determined more accurately.
Optionally, in this embodiment, if the wireless charging device detects that the device to be charged is the target device, the wireless charging device may record the identifier of the device to be charged in the first device identifier list, so as to facilitate the next detection.
As an alternative implementation, the specific implementation of S102 may also include the following steps:
the wireless charging equipment acquires the identifier of the equipment to be charged. The wireless charging equipment judges whether the identifier of the equipment to be charged exists in a first equipment identifier list pre-stored locally by the wireless charging equipment. The first device identification list comprises identifications of devices which can be successfully charged by the wireless charging device; and if the identifier of the equipment to be charged exists in the first equipment identifier list, the equipment to be charged is the target equipment. And if the identifier of the equipment to be charged does not exist in the first equipment identifier list, the wireless charging equipment sends the identifier of the equipment to be charged and the identifier of the wireless charging equipment to the server. The wireless charging equipment receives an indication message which is returned by the server and used for indicating whether the equipment to be charged is the target equipment. The indication message is obtained by the server according to the identifier of the equipment to be charged and the identifier of the wireless charging equipment; and if the indication message is used for indicating that the equipment to be charged is the target equipment, the equipment to be charged is the target equipment. And if the indication message is used for indicating that the equipment to be charged is not the target equipment, the equipment to be charged is not the target equipment.
