Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It will be apparent that the described embodiments are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by a person skilled in the art without any inventive effort, are intended to be within the scope of the present application based on the embodiments herein.
For a more complete understanding of the present application and the advantages thereof, reference is now made to the following descriptions taken in conjunction with the accompanying drawings. Wherein like reference numerals refer to like parts throughout the following description.
The embodiment of the application provides electronic equipment and a data transmission method of the electronic equipment, wherein the electronic equipment can be a mobile phone, a tablet personal computer, an intelligent watch/bracelet, an earphone, a vehicle-mounted audio system and the like.
For example, referring to fig. 1, fig. 1 is a schematic structural diagram of an electronic device 100 according to an embodiment of the present application. The electronic device 100 includes a bluetooth module, such as the first bluetooth module 110, and a UWB module, such as the first UWB module 120. The first bluetooth module 110 and the first UWB module 120 are integrated with, for example, a motherboard of the electronic device 100. The first UWB module 120 is used for positioning, ranging, data transmission, etc. The first bluetooth module 110 may be BLE (Bluetooth Low Energe, bluetooth low energy) or classical bluetooth, for example.
The first bluetooth module 110 is communicatively coupled to the first UWB module 120.
When the data amount of the data to be transmitted between the electronic device and the remote device exceeds a preset threshold, the first bluetooth module 110 wakes up the first UWB module 120, so that the first UWB module 120 and the remote device perform transmission of the data to be transmitted.
The transmission rate of the first Bluetooth module is far lower than that of the first UWB module, so that when the data volume of the data to be transmitted of the electronic equipment and the remote equipment exceeds a preset threshold value, the first Bluetooth module wakes up the first UWB module to switch the first UWB module to transmit the large quantity of data to be transmitted, and the data transmission efficiency of the electronic equipment can be ensured. And the first UWB module is connected and managed through the first Bluetooth module, the first UWB module does not need to keep a working state at any time, the power consumption of the first UWB module is reduced, the cruising ability of the electronic equipment is improved, and the connection management of the first UWB module is simplified.
It should be noted that the preset threshold may be set according to needs, for example, the preset threshold may be a data amount of one picture. The data to be transmitted whose data amount exceeds a preset threshold includes, for example, audio stream data, video stream data, picture data, installation packets, or the like.
In some embodiments, the electronic device 100 may further include a control module that confirms whether data transmission with a remote device is required and obtains the data amount of the data to be transmitted. If the data amount exceeds the preset threshold, a control signal is sent to the first Bluetooth module 110; the first bluetooth module 110 sends a wake-up instruction to the first UWB module 120 based on the control signal to wake up the first UWB module 120 in a sleep state or a shutdown state; after the first UWB module 120 is awakened, establishing a UWB communication channel with the remote device; the data to be transmitted is transmitted through the UWB communication channel. When the electronic device and the remote device transmit the instruction or the data with small data volume, the first Bluetooth module can be used for transmission continuously. Specifically, if the data amount of the data to be transmitted does not exceed the preset threshold, the data to be transmitted may be continuously transmitted through the bluetooth communication channel established between the first bluetooth module 110 and the remote device.
In some embodiments, the first bluetooth module 110 may acquire the data amount of the data to be transmitted, and determine whether the data amount exceeds a preset threshold. If the data amount exceeds the preset threshold, the first bluetooth module 110 sends a wake-up instruction to the first UWB module 120 to wake up the first UWB module 120 in the sleep state or the shutdown state; after the first UWB module 120 is awakened, establishing a UWB communication channel with the remote device; the data to be transmitted is transmitted through the UWB communication channel.
In other embodiments, the first bluetooth module 110 of the electronic device 100 wakes up the first UWB module 120 based on a switching instruction sent by the remote device, so as to switch the first UWB module 120 to perform the transmission of the data to be transmitted. The handover command includes, for example, information that data transmission with the remote device is required and the amount of data to be transmitted exceeds a preset threshold.
The electronic device can confirm whether data transmission with the remote device is needed or not according to an operation instruction sent by a user, such as transmitting pictures, audios, videos or files among different devices, and the electronic device can also confirm whether data transmission with the remote device is needed or not according to an application program, such as automatically transmitting the next audio/video file by an audio/video application program.
For ease of understanding, the electronic device 100 is taken as a mobile phone, and the remote device is taken as a wireless earphone. In the initial state, the Bluetooth module of the mobile phone is connected with the Bluetooth module of the wireless earphone, and the UWB module of the mobile phone is in a dormant state. When a user sends out an operation instruction for starting to play audio, for example, the control module sends out a control signal to the Bluetooth module after determining that the data volume of the data to be transmitted exceeds a preset threshold value so as to enable the Bluetooth module to wake up the UWB module; the UWB module establishes a UWB communication channel with UWB of the wireless headset such that audio data is transmitted to the wireless headset through the UWB communication channel. The processing unit of the wireless earphone can convert the received audio data into an analog signal which can be understood by human ears and amplify the analog signal so that the human ears can hear the audio. Because the transmission rate of UWB is greater than Bluetooth and the interference is smaller, the audio transmission is faster, and thus the delay of the earphone end is smaller. Especially for the electronic contest earphone, the played audio needs to be synchronous with the game picture, and the earphone with small delay can bring better game experience to the user. In other examples, when the bluetooth module of the handset receives a switch instruction sent by the wireless headset, the UWB module of the handset is awakened to enable the UWB module of the handset to establish a UWB communication channel with the UWB of the wireless headset, so that the handset transmits, for example, audio data to the wireless headset via the UWB communication channel to wait for data to be transmitted.
For ease of understanding, the following description will take electronic device 100 as a wireless headset and the remote device as a mobile phone. In the initial state, the Bluetooth module of the mobile phone is connected with the Bluetooth module of the wireless earphone, and the UWB module of the wireless earphone is in the dormant state. When the mobile phone and the wireless earphone need to transmit data, the mobile phone determines that the data volume of the data to be transmitted exceeds a preset threshold value, a switching instruction is sent to the wireless earphone, and when the Bluetooth module of the wireless earphone receives the switching instruction sent by the mobile phone, the UWB module is awakened, so that a UWB communication channel is established between the UWB module and the UWB of the mobile phone, and the wireless earphone transmits, for example, audio data through the UWB communication channel to wait for transmitting the data. In other examples, when the mobile phone and the wireless earphone need to transmit data, the bluetooth module of the wireless earphone determines that the data volume of the data to be transmitted exceeds a preset threshold, and then sends a switching instruction to the mobile phone, and at the same time wakes up the UWB module. When the Bluetooth module of the mobile phone receives the switching instruction sent by the wireless earphone, the UWB module of the mobile phone is awakened to enable the UWB module of the mobile phone to establish a UWB communication channel with UWB of the wireless earphone, and therefore the wireless earphone transmits, for example, audio data through the UWB communication channel to wait for data transmission.
In some embodiments, the first bluetooth module 110 is configured to send a wake-up instruction to the first UWB module 120 to wake up the first UWB module 120, while sending configuration parameters to the first UWB module 120.
The configuration parameters are obtained by negotiating with the remote device by the first bluetooth module 110, including the address, the transmission power, etc. of the first UWB module 120.
The wake-up instruction is used to wake up the first UWB module to begin operation with the configuration parameters. The wake-up instruction carries, for example, a clock offset, and the first UWB module 120 can determine a second clock according to the first clock of the first bluetooth module 110 and the clock offset, and perform data transmission with the remote device based on the second clock.
For example, referring to fig. 2, fig. 2 is a schematic diagram illustrating data transceiving timing sequences of the first bluetooth module 110 and the first UWB module 120 according to the embodiments of the present application. The first time sequence S1 of the first bluetooth module 110 includes a first time t1, and the first bluetooth module 110 transmits data at the first time t 1. The second timing S2 of the first UWB module 120 includes a second time t2, where the second time t2 is a time when the first UWB module 120 starts to transmit data after waking up. The second time t2 may be, for example, a time when the clock offset Toffset passes through the first time t 1.
After the first UWB module 120 wakes up, UWB communication is established with the remote device and data transmission is performed with the remote device.
In some embodiments, the process of establishing UWB communication between the first UWB module 120 and the remote device is, for example, that the first bluetooth module 110 requests the first UWB module 120 to acquire attribute parameters of the first UWB module 120; the first UWB module 120 transmits attribute parameters to the first bluetooth module 110 based on the request; the first bluetooth module 110 sends the attribute parameters to the remote device; the remote device requests to establish UWB communication with the first UWB module 120 based on the received attribute parameters, so that the first UWB module 120 can establish UWB communication with the remote device. In other embodiments, the first bluetooth module 110 obtains UWB attribute parameters of the remote device and transmits them to the first UWB module 120, such that the first UWB module 120 requests to establish UWB communication with the remote device based on the received UWB attribute parameters, so that the first UWB module 120 can establish UWB communication with the remote device. The attribute parameter includes, for example, an identification code of the first UWB module 120 or a channel that the first UWB module 120 can identify and select based on itself.
In some embodiments, the first bluetooth module 110 is further configured to determine whether the data transmission is finished according to an instruction sent by the remote device or according to a control signal of the control module, and if so, send a sleep instruction to the first UWB module 120 to make the first UWB module 120 enter a low power consumption mode. Or, the data packet transmitted by the first UWB module 120 carries a FLAG that whether there is any data to be transmitted, and when the FLAG is detected to be 0, the first UWB module 120 enters the low power consumption mode by itself. The first UWB module 120 is in a low power consumption mode, such as turning off the radio frequency transmission link.
According to the electronic device 100 provided by the embodiment of the application, since the transmission rate of the first bluetooth module is far lower than that of the first UWB module, when the electronic device needs to transmit a large amount of data with the remote device, the data amount of which exceeds the preset threshold value, the first bluetooth module 110 wakes up the UWB module to switch to the first UWB module 120 for transmitting the data to be transmitted, so that the data transmission efficiency of the electronic device can be ensured. Moreover, the first bluetooth module 110 is used for performing connection management on the first UWB module 120 and clock synchronization management with a remote device, the first UWB module 120 does not need to keep a working state at any time, power consumption of the first UWB module 120 is reduced, cruising ability of the electronic device is improved, and management of working clock and connection maintenance of the first UWB module 120 is simplified.
The embodiment of the present application further provides a data transmission system, and exemplary, please refer to fig. 3-4. Fig. 3 is a schematic diagram of a data transmission system according to an embodiment of the present application. Fig. 4 is a schematic diagram of data transceiving time sequences of the first bluetooth module 110, the second bluetooth module 210, the first UWB module 120 and the second UWB module 220 in the data transmission system according to the embodiment of the present application.
The data transmission system comprises an electronic device 100 and a remote device 200. The electronic device 100 may, for example, act as a master device, while the remote device 200 acts as a slave device; alternatively, the electronic device 100 acts as a slave device and the remote device 200 acts as a master device; or both the electronic device 100 and the remote device 200 act as slaves.
Wherein the remote device 200 includes a bluetooth module, such as a second bluetooth module 210, and a UWB module, such as a second UWB module 220.
The first bluetooth module 110 is configured to broadcast and send its own device information within a certain distance, and the second bluetooth module 210 is configured to obtain the device information of the first bluetooth module 110 by scanning a broadcast packet, and if the pairing requirement is met, the first bluetooth module 110 and the second bluetooth module 210 can be connected.
After the first bluetooth module 110 and the second bluetooth module 210 are successfully connected, a transmission link between the first UWB module 120, the first bluetooth module 110, the second bluetooth module 210, and the second UWB module 220 is formed.
In some embodiments, after the first UWB module 120 and the second UWB module 220 wake up, the first bluetooth module 110 reports the device information of the remote device 200 to the first UWB module 120 and requests the attribute parameters of the first UWB module 120; the first UWB module 120 transmits the attribute parameters to the second UWB module 220 through a transmission link; the second UWB module 220 is initialized after receiving the attribute parameters, and establishes UWB communication connection with the first UWB module 120, and after the connection is successful, data transmission can be performed. If the attribute parameters of the first UWB module 120 change, the new attribute parameters may be sent to the second UWB module 220 again through the bluetooth transmission link, so as to reestablish the connection between the first UWB module 120 and the second UWB module 220.
After the UWB data transmission is completed, the first UWB module 120 is disconnected from the second UWB module 220 and enters a low power consumption mode.
At this time, the first bluetooth module 110 remains connected to the second bluetooth module 210, and the first bluetooth module 110 periodically transmits a data packet to the second bluetooth module 210, where the data packet carries, for example, a time point of transmission thereof, i.e., a time point of packet transmission. The second bluetooth module 210 can maintain clock synchronization with the first bluetooth module 110 according to the packet transmission timing point.
In the embodiment where the first bluetooth module 110 and the second bluetooth module 210 are both slave devices, the remote host device periodically sends data packets to the first bluetooth module 110 and the second bluetooth module 210, so that the first bluetooth module 110 and the second bluetooth module 210 keep clock synchronization with the remote host device.
When the UWB needs to be started again between the electronic device 100 and the remote device 200 for data transmission, the first bluetooth module 110 sends a first wake-up instruction to the first UWB module 120, and the second bluetooth module 210 sends a second wake-up instruction to the second UWB module 220, so that the first UWB module 120 and the second UWB module 220 reestablish communication connection after waking up, thereby performing data transmission. The UWB reconnection process is rapid, and the use experience of a user can be improved.
The first UWB module 120 determines a second clock according to the first clock of the first bluetooth module 110 and the clock offset if the first wake-up instruction and the second wake-up instruction carry the clock offset; the second UWB module 220 determines a fourth clock according to the third clock and the clock offset of the second bluetooth module 210. The first UWB module 120 and the second UWB module 220 remain clock synchronized while the first bluetooth module 110 and the second bluetooth module 210 remain clock synchronized.
Referring to fig. 4, tx represents transmission and RX represents reception. The working time sequence of the first bluetooth module 110 is the first time sequence S1, the working time sequence of the second bluetooth module 210 is the third time sequence S3, and since the first bluetooth module 110 and the second bluetooth module 210 are in clock synchronization, when the first bluetooth module 110 is at the data sending time, the second bluetooth module 210 is at the data receiving time; when the first bluetooth module 110 is at the time of data reception, the second bluetooth module 210 is at the time of data transmission.
The working time sequence of the first UWB module 120 is the second time sequence S2, the working time sequence of the second UWB module 220 is the fourth time sequence S4, and since the first UWB module 120 and the second UWB module 220 are clock-synchronized, the second UWB module 220 is at the data receiving time when the first UWB module 120 is at the data transmitting time; when the first UWB module 120 is at the time of data reception, the second UWB module 220 is at the time of data transmission.
The first timing of the first bluetooth module 110 includes, for example, a third time t3, and the fourth time t4 when the first UWB module 120 and the second UWB module 220 start transmitting and receiving data is, for example, a time when the third time t3 passes through the clock offset Toffset.
The embodiment of the application further provides a data transmission method, and referring to fig. 5, fig. 5 is a first flowchart of the data transmission method provided in the embodiment of the application. The data transmission method is applied to electronic equipment, and the electronic equipment comprises a Bluetooth module and a UWB module.

The Bluetooth module and the UWB module are integrated on a main board of the electronic equipment and are in communication connection. The Bluetooth module is also in communication with the remote device. The data transmission method includes steps S101 and S102:
s101: when the data volume of the data to be transmitted between the electronic equipment and the remote equipment exceeds a preset threshold value, the Bluetooth module wakes up the UWB module;
and if the data quantity of the data to be transmitted does not exceed the preset threshold value, transmitting the data to be transmitted by the Bluetooth module.
The preset threshold is, for example, the data amount of one picture. The data to be transmitted whose data amount exceeds a preset threshold includes, for example, audio stream data, video stream data, picture data, installation packets, or the like.
S102: and the UWB module and the remote equipment perform data transmission to be transmitted.
In practical applications, the electronic device is, for example, a mobile phone, and the remote device is a wireless earphone, a car audio system, or the like. When the mobile phone needs to transmit a large amount of data such as audio data, video data, picture data, installation packages and the like to the wireless earphone/vehicle-mounted audio system, the UWB module is awakened through the Bluetooth module, so that the data is transmitted through a UWB communication channel established by the UWB module.

in the initial state, the UWB module is in a sleep state.
S202: the UWB module determines a second clock according to the first clock and the clock offset of the Bluetooth module;
