The application provides a data transmission device 10, and the data transmission device 10 is applied to a multi-sensor input and output device. The multi-sensor input/output device may be a vr (virtual reality) device, an ar (augmented reality) device, or the like.
Taking a multi-sensor input and output device as a VR device and a data processing terminal as a mobile phone as an example, a camera, a display, a speaker, a microphone and various sensors, such as a vibration sensor, for acquiring vibration information of the current VR device are configured in the VR device; the depth of field sensor is used for acquiring the depth of field of the current environment; the infrared sensor is used for acquiring infrared intensity information of the current environment; and the like.

The mobile phone processes the information transmitted by the VR equipment to generate corresponding video data information and voice information and then transmits the video data information and the voice information to the VR glasses, and the VR glasses decode and display the video data information and play voice through the loudspeaker after receiving the video data information.
In the process, the VR device and the mobile phone perform signal transmission twice, and the signal transmission is performed respectively by the VR device sending the detection signal to the mobile phone and the mobile phone sending the generated video data information to the VR glasses. Because the VR device and the mobile phone are electronic products in two different fields and have different platform architectures, each signal transmission needs to process a data format.
Referring to fig. 1, fig. 1 is a schematic structural diagram of a data transmission device 10 according to an embodiment of the present disclosure.
As shown, the data transmission device 10 includes a first transmission line 11, a second transmission line 12, and a repeater 13. A first end of the first transmission line 11 is configured to be connected to a multi-sensor input-output device, a first end of the second transmission line 12 is configured to be connected to a data processing terminal, and the repeater 13 is connected to a second end of the first transmission line 11 and a second end of the second transmission line 12, respectively. The data processing terminal can be a mobile terminal with processing function, such as a mobile phone and a computer.
Specifically, the first transmission line 11 is used to transmit first data, and the second transmission line 12 is used to transmit second data. The data format of the first data is the data format required by the multi-sensor input and output equipment, the data format of the second data is the data format required by the data processing terminal, and the data format of the second data is different from that of the first data.
The first transmission line 11 realizes bidirectional transmission of first data between the multi-sensor input and output device and the repeater 13, and the second transmission line 12 realizes bidirectional transmission of second data between the repeater 13 and the output processing terminal. The data format required by the multi-sensor input and output device is the data format of the data to be received or transmitted by the multi-sensor input and output device, and the data format required by the data processing terminal is the data format of the data to be received or transmitted by the data processing terminal.
The data format types of the first data and the second data may be multiple, and the data format of the first data and the data format of the second data may be a data format such as MIPI (Mobile Industry Processor Interface), USB (Universal Serial BUS), DP (Display Port, high-definition digital Display Interface), and the like.
For example, the multi-sensor i/o device transmits data in MIPI format to the repeater 13, and the data format of the first data is in MIPI format. The repeater 13 transmits the data of the USB format to the data processing terminal, and the data format of the second data at this time is the USB format.
Specifically, the repeater 13 is configured to perform data format interconversion between the first data and the second data. The relay 13 may convert the data format of the first data into the data format of the second data, or may convert the data format of the second data into the data format of the first data.
For example, after the repeater 13 receives the first data from the first transmission line 11 and needs to transmit the first data to the data processing terminal, the data format of the first data is converted into the data format of the second data, and at this time, the first data is changed into the second data, and the repeater 13 further transmits the second data to the data processing terminal through the second transmission line 12. After the repeater 13 receives the second data from the second transmission line 12, the second data needs to be transmitted to the multi-sensor input/output device, the data format of the second data is converted into the data format of the first data, at this time, the second data is changed into the first data, and the repeater 13 further transmits the first data to the multi-sensor input/output device through the first transmission line 11.
The repeater 13 may also perform preprocessing of the data, such as data compression, analog-to-digital conversion, elimination of redundant data information, incomplete data information, etc.
Therefore, when the data transmission device 10 provided by the present application performs data transmission, the data format conversion can be realized through the repeater 13, and thus the arrangement of the data format conversion device in the multi-sensor input/output device or the data processing terminal can be reduced, and the weight and the power consumption of the multi-sensor input/output device or the data processing terminal can be reduced. Particularly, the overall performance of the multi-sensor input and output device is greatly improved due to low weight and power consumption on the premise of meeting the functions of the multi-sensor input and output device.
Referring to fig. 2, fig. 2 is a schematic structural diagram of another embodiment of a data transmission device 10 provided in the present application.
Further, the repeater 13 may include a communication circuit 131, and the communication circuit 131 is connected to the first transmission line 11 and the second transmission line 12, for obtaining a data format required by the multi-sensor input and output device through the first transmission line 11, and for obtaining a data format required by the data processing terminal through the second transmission line 12. In some embodiments, the communication circuit may be a DATA-6106 wireless DATA transfer circuit.
Specifically, the communication circuit 131 may be connected to the second end of the first transmission line 11 and the second end of the second transmission line 12, and the communication circuit 131 obtains the recognizable data signal format to the data signal receiving end and the data signal transmitting end, respectively. It should be understood that one of the multi-sensor input/output device and the data processing terminal is a data signal sending end, and the other is a data signal receiving end, and the recognizable data signal format is the data format required by the multi-sensor input/output device and the data processing terminal in the above embodiments.
The repeater 13 may further include a data conversion circuit 132, and the data conversion circuit 132 is connected to the first transmission line 11, the second transmission line 12 and the communication circuit 131, and is configured to convert the data format between the first data and the second data according to the data format required by the multi-sensor input/output device and the data format required by the data processing terminal.
Specifically, after the communication circuit 131 acquires the data format of the first data and the data format of the second data, the data conversion circuit 132 realizes the conversion of the data format between the first data and the second data according to the corresponding conversion relationship between the data format of the first data and the data format of the second data.
For example, if the data format of the first data acquired by the communication circuit 131 is a, the data format of the second data is B, and the first data needs to be converted into the second data, then the corresponding conversion relationship between the data format of the first data and the data format of the second data is: data format a is converted to data format B. Further, the data conversion circuit 132 may acquire the corresponding conversion relationship from the communication circuit 131, and accordingly implement conversion of the data format based on the conversion relationship. In other embodiments, the data conversion circuit 132 may not obtain the corresponding conversion relationship, and the communication circuit 131 may enable the data conversion circuit 132 to perform the conversion based on the corresponding conversion relationship.
Referring to fig. 3, fig. 3 is a schematic structural diagram of an embodiment of the data conversion circuit 132 of the data transmission apparatus 10 in fig. 2.
Further, in combination with the content of the above embodiment, at least two independent data conversion chips are disposed in the data conversion circuit 132, each data conversion chip is connected to the first transmission line 11 and the second transmission line 12, and different data conversion chips correspond to different data format conversion types. The communication circuit 131 selects a data conversion chip matched with the data format required by the multi-sensor input/output device and the data format required by the data processing terminal to operate.
As shown in fig. 3, the data conversion circuit 132 includes a first data conversion chip 1321 and a second data conversion chip 1322, the first data conversion chip 1321 corresponds to a first conversion format type, and the second data conversion chip 1322 corresponds to a second conversion format type. For example, the first conversion format type is: converting data format a to data format B, the second conversion format type being: data format a is converted to data format C. Then, if the data format required by the multi-sensor input/output device is data format a, the data format required by the data processing terminal is data format B, and it is necessary to convert data format a into data format B, the communication circuit 131 selects the first data conversion chip 1321 to work to implement data format conversion.

The second transmission line 12 at least includes a third transmission channel 121 and a fourth transmission channel 122 that are independent of each other, the third transmission channel 121 and the fourth transmission channel 122 are used for transmitting electrical signals, and both the third transmission channel 121 and the fourth transmission channel 122 are connected to the repeater 13 and the data processing terminal.
In combination with the above, the first transmission channel 111 and the third transmission channel 121 are high-speed data channels, and the second transmission channel 112 and the fourth transmission channel 122 are low-speed data channels.

Two optical fibers, a first optical fiber and a second optical fiber, may be further provided. Illustratively, the first optical fiber is used for transmitting one or more of an environment image signal, an environment voice signal and an environment detection signal in an MIPI format sent by the wearable device. Taking the environment image signal as an example, the data processing module converts the environment image signal into a DP format for processing by the data processing terminal. And the DP format video signal generated after the data processing terminal processes is transmitted to the data processing module, converted into the MIPI format and transmitted to the VR display through a second optical fiber.

After receiving the data signal, the first bluetooth transceiver module sends the data signal to the data conversion circuit 132 in the repeater, so that the data conversion circuit 132 performs data format conversion. Similarly, when the data processing terminal 3 sends a data signal to the wearable device 2, the data conversion circuit 132 performs format conversion on the data signal, and then sends the data signal to the multi-sensor input/output device in a wireless transmission manner through the first bluetooth transceiver module, and the multi-sensor input/output device transmits the data signal to the processing chip of the wearable device 2 in an electrically connected manner.
