After the MIPI signal transmitting apparatus 201 transmits the MIPI signal to the MIPI signal receiving apparatus 202, if the receiving chip 2022 receives the MIPI signal within the preset time period, it indicates that the th USB interface 2012 is connected to the second USB interface 2021 in the forward direction, and if the receiving chip 2022 does not receive the MIPI signal within the preset time period, it indicates that the th USB interface 2012 is connected to the second USB interface 2021 in the reverse direction, where the preset time period may be 20 ms.

It should be noted that, when the I2C of the MIPI chip 2011 is connected to the USB interface 2012, if the USB interface 2012 and the second USB interface 2021 are connected in the forward direction, the SCL of the MIPI chip 2011 corresponds to the SCL of the receiving chip 2022, and the SDA of the MIPI chip 2011 corresponds to the SDA of the receiving chip 2022, if the USB interface 2012 and the second USB interface 2021 are connected in the reverse direction, the SCL of the MIPI chip 2011 corresponds to the SDA of the receiving chip 2022, and the SDA of the MIPI chip 2011 corresponds to the SCL of the receiving chip 2022.

If the th USB interface 2012 is connected to the second USB interface 2021 in the forward direction, the MIPI signal transmitted by the MIPI signal transmission device 201 through the th USB interface 2012 is received through the second USB interface 2021, and if the th USB interface 2012 is connected to the second USB interface 2021 in the reverse direction, the MIPI signal received by the receiving chip 2022 needs to be converted according to the corresponding relationship of the data channels in the reverse connection.

Adopt above-mentioned system, MIPI signal transmission equipment passes through USB interface and MIPI signal reception equipment's second USB interface connection to through USB interface and second USB interface, with MIPI signal transmission to MIPI signal reception equipment, here, transmit the MIPI signal through the USB interface, can realize the long distance transmission of MIPI signal, and the structural strength of USB interface is better, and is not fragile in the use.

Fig. 7 is a schematic structural diagram of a third MIPI signal transmission system provided in the embodiment of the present disclosure, as shown in fig. 7, the MIPI signal receiving apparatus 202 further includes a relay chip 2023, and the relay chip 2023 is connected to the second USB interface 2021 and the receiving chip 2022;

the receiving chip 2022 is further configured to send a conversion instruction to the relay chip 2023 if the connection mode is reverse connection;

the relay chip 2023 is configured to receive the conversion instruction sent by the receiving chip 2022, and convert the MIPI signal received by the receiving chip 2022 according to the conversion instruction.

Here, after the receiving chip 2022 receives the MIPI signal, the connection state between the USB interface 2012 of the and the USB interface 2021 is obtained, if the USB interface and the USB interface 2021 are reversely connected, the receiving chip 2022 sends a conversion instruction to the relaying chip 2023, and the relaying chip 2023 converts the MIPI signal received by the receiving chip 2022 according to the conversion instruction and the corresponding relationship between the MIPI chip 2011 and the data channel of the receiving chip 2022 during reverse connection, that is, recombines the MIPI signal received by the receiving chip 2022, for example, if the MIPI signal transmitting device 201 transmits the MIPI signal through 4 data channels, the relaying chip 2023 may swap the MIPI D1 +/-and the MIPI D2 +/-of the receiving chip 2022, swap the MIPI D3 and the MIPI D4 +/-of the receiving chip 2022, and then reassemble data of the 4 channels that are swapped, so as to obtain the converted MIPI signal.

It should be noted that, if the th USB interface 2012 is connected to the second USB interface 2021 in the forward direction as a reference, the MIPI signal received by the receiving chip 2022 may be converted when the th USB interface 2012 is connected to the second USB interface 2021 in the reverse direction, and if the th USB interface 2012 is connected to the second USB interface 2021 in the reverse direction as a reference, the MIPI signal received by the receiving chip 2022 may also be converted when the th USB interface 2012 is connected to the second USB interface 2021 in the forward direction.

Considering that different MIPI signal transmission devices 201 can be connected according to actual requirements for the MIPI signal receiving device 202, for example, for an unmanned aerial vehicle, according to a shooting scene, a shooting target, a shooting speed, and the like, a corresponding camera can be selected, for example, when shooting a night scene, a camera with a better night shooting effect can be selected, and when shooting a landscape, a camera with a panoramic function can be selected, so that a better shooting effect can be achieved; in addition, for unmanned aerial vehicle equipment manufacturers, in the unmanned aerial vehicle test phase, various cameras need to be adapted for debugging. Therefore, the MIPI signal receiving device 202 needs to acquire the connection state of the MIPI signal transmitting device 201, and complete corresponding processing operations according to the connection state, for example, when the MIPI signal transmitting device 201 is disconnected from the MIPI signal receiving device 202, the MIPI signal receiving device 202 needs to store the image data that has been captured, and when the MIPI signal transmitting device 201 is reconnected to the MIPI signal receiving device 202, the MIPI signal receiving device 202 needs to trigger an initialization operation on the MIPI chip 2011. In this case, when the MIPI signal transmission apparatus 201 is disconnected or connected to the MIPI signal reception apparatus 202, the disconnected or connected state needs to be transmitted to the MIPI signal reception apparatus 202.

Here, SBU2 of USB interface 2012 is connected at a level opposite to the polarity of the preset level of SBU1, i.e., SBU2 is connected at a high level when the preset level of SBU1 is at a low level, and SBU2 is connected at a low level when the preset level of SBU1 is at a high level.

The current level of the SBU1 of the USB interface 2012 is equal to the level of the SBU2 when the MIPI signal transmitting device 201 is connected to the MIPI signal receiving device 202, i.e. the current level of the SBU1 is opposite to the polarity of the preset level of the SBU1, so that the current level of the SBU1 of the second USB interface 2021 of the MIPI signal receiving device 202 is also opposite to the polarity of the preset level of the SBU1, indicating that the connection state of the MIPI signal transmitting device 201 and the MIPI signal receiving device 202 is connected, when the MIPI signal transmitting device 201 is disconnected from the MIPI signal receiving device 202, the current level of the SBU2 of the USB interface 2012 is equal to the polarity of the preset level of the SBU1, the polarity of the MIPI signal transmitting device 202 is the same as the polarity of the preset level of the MIPI signal transmitting device 1, the MIPI signal receiving device 202 is disconnected from the MIPI signal receiving device 202, and the MIPI signal transmitting device 201 is also equal to the MIPI signal receiving device 202, thus the MIPI signal transmitting device 202 is capable of achieving the same polarity relationship between the MIPI signal transmitting function of the MIPI signal transmitting device 201 and the MIPI signal receiving device 3884, and the MIPI signal receiving device 202.

Adopt above-mentioned system, MIPI signal transmission equipment passes through USB interface and MIPI signal reception equipment's second USB interface connection to through USB interface and second USB interface, with MIPI signal transmission to MIPI signal reception equipment, here, transmit the MIPI signal through the USB interface, can realize the long distance transmission of MIPI signal, and the structural strength of USB interface is better, and is not fragile in the use.
