Detailed Description
To make the objects, technical solutions and advantages of the present application more clear, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.
Referring to fig. 1, a schematic diagram of an implementation environment provided by an example of the present disclosure is shown. The implementation environment includes a wireless charging device 11, a first terminal 12, and a second terminal 13.
The wireless charging device 11 is a device for supplying power to a power-consuming device during wireless charging. When the wireless charging device is used for wirelessly charging a portable electronic device such as a mobile phone, a tablet computer, and a wearable device, the wireless charging device 11 may be referred to as a charger, a charging tray, a power adapter, a wireless charger, and the like.
The wireless charging device 11 is provided with a charging chip to implement a function of supplying power to the second terminal 13. In the embodiment of the present disclosure, the wireless charging apparatus 11 also has a data transmission function. During the process that the wireless charging device 11 supplies power to the first terminal 12, the wireless charging device can realize data transmission between the first terminal 12 and the second terminal 13 through the data transmission function.
Specifically, the wireless charging device 11 is provided therein with a first communication module and a second communication module. The wireless charging device 11 realizes communication with the first terminal 12 through the first communication module, and realizes communication with the second terminal 13 through the second communication module. The first communication module and the second communication module may be the same communication module or different communication modules. Alternatively, the first communication module may be a radio frequency module including a millimeter wave wireless transmission chip. Alternatively, the second communication module may be a USB module.
Optionally, the wireless charging device 11 also has a data storage function. Specifically, the wireless charging device 11 is built with a memory for realizing the above-described data storage function, for example, storing a program or the like necessary for executing the data transmission scheme provided by the embodiment of the present disclosure.
The first terminal 12 may be a mobile phone, a tablet Computer, a Personal Computer (PC). The second terminal 13 is a communication device that can be wirelessly charged by the wireless charging device 11. The second terminal 13 may be a cell phone, a tablet, a wearable device, etc.
The wireless charging device 11 and the first terminal 12 establish a first communication connection, which may be a wireless communication connection established based on a radio frequency module. A second communication connection is established between the wireless charging module 11 and the second terminal 13, and the second communication connection may be a wired connection or a wireless connection.
Referring collectively to fig. 2, a schematic diagram of a data transmission system is shown, according to one embodiment of the present disclosure. The second terminal 21 includes a processor, a radio frequency module and a power module, both of which are connected to the processor. The wireless charging device 22 includes a radio frequency module and a power supply module. The second terminal 21 and the wireless charging device 22 establish a wireless connection based on the radio frequency module, and the wireless charging device 22 and the first terminal 23 establish a USB connection.
The related art also provides a wireless charging scheme, namely, the mobile terminal is charged through the wireless charging equipment. At present, when the mobile terminal is charged through the wireless charging equipment, strict requirements are required for the placement position of the mobile terminal on the wireless charging equipment, and the convenience of data transmission between the mobile terminal and a computer is poor under the condition.
Based on this, the embodiment of the disclosure provides a data transmission method and device based on a wireless charging device. In the embodiment of the disclosure, the wireless charging device is respectively in communication connection with the two terminals, and then the wireless charging device is used as a medium for data transmission between the two terminals, so that the situation that the mobile terminal is connected with the other terminal in a wired manner to perform data transmission in a wireless charging scene can be avoided, and the convenience of data transmission between the mobile terminal and the other terminal in the wireless charging scene is improved.
Referring to fig. 3, a flowchart of a data transmission method based on a wireless charging device according to an embodiment of the present disclosure is shown. The method can be applied to the wireless charging device 11 in the implementation environment shown in fig. 1, and comprises the following steps:
In step 301, a first communication connection is established with a first terminal.
The first terminal is a terminal which does not need the wireless charging device to supply power. The first terminal may be a personal computer, a smart phone, a tablet computer, etc., and in the embodiment of the present disclosure, only the first terminal is taken as the personal computer for explanation. The first communication connection may be a wired connection or a wireless connection. The first communication connection may be a USB connection if the first communication connection is a wired connection. If the first communication connection is a wireless connection, the first communication connection may be a bluetooth connection, a WiFi connection, or the like. In the embodiment of the present disclosure, only the first communication connection is described as an example of a USB connection.
In step 302, when it is detected that the wireless charging device is supplying power to the second terminal, a second communication connection is established with the second terminal based on the radio frequency module.
The second terminal is a terminal which needs the wireless charging device to supply power. The second terminal can be a smart phone, a tablet computer, an intelligent wearable device and the like. In the embodiment of the present disclosure, the explanation is performed only by taking the second terminal as a smart phone as an example.
Optionally, the radio frequency module includes a millimeter wave wireless transmission chip. The millimeter wave wireless transmission chip is a chip for data transmission based on millimeter waves. The millimeter wave wireless transmission chip has the following characteristics:
(1) The working frequency is between 30Ghz and 300Ghz, and the interference in the data transmission process is small in the frequency band.
(2) The transmission rate is between 1Mbits/s and 6Gbit/s, and the transmission rate is very fast.
(3) The transmission mode may be a half-duplex mode or a full-duplex mode. The half-duplex mode allows data to be transmitted in both directions, but only in one direction at a time. The full duplex mode allows data to be transmitted in both directions simultaneously.
(4) The transmission distance is relatively short, typically within 15 mm.
(5) The requirements on the distance and the position relation between the home terminal and the opposite terminal are higher. If the distance and the position relation do not satisfy the preset conditions, the situation that the transmission rate is slow or even the transmission cannot be performed may occur.
It should be noted that, because the transmission distance of the millimeter wave wireless transmission chip is limited, in the process of supplying power to the second terminal, the distance between the millimeter wave wireless transmission chip and the radio frequency module in the second terminal is smaller than a preset threshold, and the preset threshold is determined according to the transmission distance of the millimeter wave wireless transmission chip. Optionally, the preset threshold is also a transmission distance of the millimeter wave wireless transmission chip.
It should be noted that, because the millimeter wave wireless transmission chip has a high requirement on the position relationship with the opposite terminal when performing data transmission, in the process of supplying power to the second terminal, the relative position relationship between the millimeter wave wireless transmission chip and the radio frequency module in the second terminal meets the preset condition. The preset condition may be that the millimeter wave wireless transmission chip and the radio frequency module in the second terminal are arranged oppositely, i.e. parallel to each other, in the process of supplying power to the second terminal.
In a possible implementation manner, the radio frequency module includes two groups of millimeter wave wireless transmission chips, where one group of millimeter wave wireless transmission chips is used to implement a data sending function, and the other group of wireless millimeter wave wireless transmission chips is used to implement a data receiving function. In another possible implementation manner, the radio frequency module includes a group of millimeter wave wireless transmission chips, and the group of millimeter wave wireless transmission chips is used for implementing a data sending function and a data receiving function.
Optionally, the wireless charging device first detects whether the wireless charging device is in a state of supplying power to the second terminal, and if the wireless charging device is in the state of supplying power to the second terminal, establishes a second communication connection, that is, a wireless connection, with the second terminal. Specifically, the wireless charging device detects whether the wireless charging device is in a working state, and then detects whether a relative position relationship between the second terminal and the wireless charging device meets a first preset condition. The first preset condition refers to a relative position relationship between the second terminal and the wireless charging device when the second terminal is charged through the wireless charging device. And if the wireless charging equipment is in a working state and the relative position relation between the second terminal and the wireless charging equipment meets a first preset condition, determining that the wireless charging equipment is in a state of supplying power to the second terminal.
In addition, when the wireless charging device is in communication connection with the first terminal and is in the process of supplying power to the second terminal, the radio frequency module is switched from the dormant state to the awakening state, and then the second communication connection is established with the second terminal based on the radio frequency module, so that the radio frequency module is prevented from being always kept in the awakening state when the data transmission requirement between the first terminal and the second terminal does not exist, and the power consumption of the wireless charging device can be saved.
In step 303, during the process of supplying power to the second terminal, data transmission is performed between the first terminal and the second terminal through the first communication connection and the second communication connection.
In the embodiment of the disclosure, when the second terminal is in a wireless charging scenario, the wireless charging device supplying power to the second terminal is used as a data transmission medium, so that data transmission between the first terminal and the second terminal is realized, the situation that the mobile terminal is connected with another terminal in a wired manner to perform data transmission in the wireless charging scenario can be avoided, and the convenience of performing data transmission between the mobile terminal and the another terminal in the wireless charging scenario is improved.
Optionally, step 303 is implemented as: the data are transmitted between the first terminal and the wireless charging device through the first communication connection, and the data are transmitted between the wireless charging device and the second terminal through the second communication connection.
The wireless charging device transmitting data between the first terminal and the wireless charging device through the first communication connection may include: and receiving data sent by the first terminal through the first communication connection, or sending data to the first terminal through the first communication connection. During data transmission between the wireless charging device and the first device, data transmission may be performed based on the USB3.0 protocol. The USB3.0 protocol may also be referred to as "superspeeded USB," which has a faster transmission rate than the conventional USB2.0 protocol.
The wireless charging device connecting the wireless charging device and the second terminal through the second communication to transmit data may include: and receiving the data sent by the second terminal through the second communication connection, or sending the data to the second terminal through the second communication connection.
In addition, in a wireless charging scenario, data transmission between the first terminal and the second terminal may be initiated by a user. In an example, the wireless charging device sends a connection establishment notification to the first terminal and the second terminal respectively when the first communication connection and the second communication connection are both established, where the connection establishment notification may include an identifier of the first terminal and an identifier of the second terminal, and both the first terminal and the second terminal may display a prompt message on a current user interface to prompt that data transmission may be performed between the first terminal and the second terminal. When the first terminal or the second terminal receives the confirmation instruction corresponding to the prompt message, a data transmission interface can be displayed, a user selects data to be transmitted on the data transmission interface, a data transmission instruction is triggered, and then data transmission is carried out between the first terminal and the second terminal based on the first communication connection and the second communication connection.
Referring collectively to fig. 4, a data transmission diagram illustrating one embodiment of the present disclosure is shown. The master device 41 (i.e., the second terminal) includes a radio frequency module, the radio frequency module includes a transmitting component and a receiving component, the slave device 42 (i.e., the wireless charging device) also includes a radio frequency module, the radio frequency module also includes a transmitting component and a receiving component, and data transmission is performed between the slave device and other devices based on the USB3.0 data transmission protocol.
To sum up, according to the technical scheme provided by the embodiment of the present disclosure, the wireless charging device is respectively connected to the two terminals in a communication manner, and then the wireless charging device is used as a medium for data transmission between the two terminals, so that a situation that the mobile terminal is connected to another terminal in a wired manner to perform data transmission in a wireless charging scene can be avoided, and convenience of data transmission between the mobile terminal and the another terminal in the wireless charging scene is improved. In addition, the wireless charging equipment establishes communication connection with the second terminal after establishing communication connection with the first terminal, so that the communication connection between the wireless charging equipment and the second terminal is avoided being established under the condition that no data transmission requirement exists, and the power consumption of the wireless charging equipment can be saved.
In addition, data transmission between the wireless charging equipment and the second terminal is achieved through the micron-wave wireless data transmission chip, the transmission speed is high, and the anti-interference capability is strong. In addition, data transmission between the wireless charging device and the first terminal is realized through a USB3.0 protocol, and the data transmission efficiency can be improved.
In an optional embodiment provided based on the embodiment shown in fig. 3, the method for transmitting data based on a wireless charging device may further include the following steps: and when the disconnection of the second communication connection is detected, sending a disconnection notice to the first terminal.
The disconnection notification is used to notify that the second communication connection has been disconnected, and optionally, the disconnection notification includes an identifier of the second terminal. The disconnection notification is used for indicating the first terminal to transmit data according to the third communication connection when detecting that the third communication connection is established between the first terminal and the second terminal. The third communication connection may be a bluetooth connection, a WiFi connection, a USB connection, or the like.
In this disclosure, when the data transmission task between the first terminal and the second terminal is not completed, if the second communication connection is disconnected and a third communication connection exists between the first terminal and the second terminal, the wireless charging device may instruct the first terminal and the second terminal to continue to perform the unfinished transmission task through the third communication connection. By the method, when the data transmission scheme based on the wireless charging device is interrupted, the first terminal and the second terminal can continue data transmission.
Accordingly, the data transmission method based on the wireless charging device may further include the steps of: and when the disconnection of the first communication connection is detected, sending a disconnection notice to the second terminal. The disconnection notification is used to notify that the first communication connection has been disconnected, optionally, the disconnection notification includes an identification of the first terminal. The disconnection notification is used for indicating the second terminal to transmit data according to the third communication connection when detecting that the third communication connection is established between the first terminal and the second terminal.
To sum up, according to the technical solution provided in the embodiment of the present disclosure, when the first communication connection or the second communication connection is disconnected, if the third communication connection is established between the first terminal and the second terminal, the first terminal and the second terminal may continue to perform an unfinished transmission task, so as to avoid interruption of data transmission due to disconnection of the first communication connection or the second communication connection.
In an optional embodiment provided based on the embodiment shown in fig. 3, the method for transmitting data based on a wireless charging device may further include the following steps: and sending a connection establishment notification to the first terminal.
The connection establishment notification is used for notifying the second terminal that the second communication connection is established with the wireless charging device. The connection notification carries an identifier of the second terminal. The disconnection notification is used for instructing the first terminal to execute an uncompleted data transmission task through the first communication connection when detecting that the uncompleted data transmission task exists.
In this disclosure, when the first terminal and the second terminal both establish a communication connection with the wireless charging device and an unfinished data transmission task exists between the first terminal and the second terminal, the wireless charging device may instruct the first terminal and the second terminal to continue to perform the unfinished data transmission task. By the method, when the unfinished data transmission task exists between the first terminal and the second terminal, a user does not need to manually select the unfinished transmission task and trigger the unfinished transmission task, and the data transmission efficiency under the condition that the unfinished transmission task exists can be improved.
