Description

Technical Field

[0001] This utility model relates to the field of automotive electronic circuit technology, and more specifically, to a data conversion device, system, and debugging equipment. Background Technology

[0002] Currently, with the widespread application of high-speed video signals in the fields of intelligent driving and smart cockpits, the task of interconnecting and debugging cameras and controllers is also facing challenges.

[0003] Most existing automotive cameras have serial chips that can serially convert MIPI video signals from mobile processor interfaces into FPD-Link video signals for tablet displays, which are then transmitted to the controller or vehicle infotainment system via coaxial / differential video cables. During debugging, the compatible automotive controller must also be able to receive FPD-Link video signals to correctly receive the video signals output by the camera.

[0004] In existing solutions, whether debugging the camera or the controller, the communication method between the camera and the controller must be consistent. If debugging is only required, the other end equipment needs to be prepared, and the technical barriers of the other end equipment may even delay the overall development schedule of the project, which undoubtedly increases the time and development costs.

The deserializer chip 2 is connected to the serializer chip 3. The serializer chip 3 is connected to the second video connector 4.

[0051] The first video connector 1 is used to receive FPD-Link video signal data from the FPD-Link camera 5; the deserializer chip 2 is used to deserialize the FPD-Link video signal data into MIPI (Mobile Industry Processor Interface) data. Specifically, the deserializer chip 2 can deserialize the FPD-Link video signal data into MIPI CSI-2 (Mobile Industry Processor Interface Camera Serial Interface 2) data.

This ensures consistent communication between the FPD-Link camera 5 and the GMSL controller 6, avoiding the need to prepare the other end equipment when debugging cameras or controllers with different interfaces. This shortens the project cycle, reduces technical difficulty, and significantly reduces time and R&D costs.

[0055] See also Figure 1 The data conversion device provided in this embodiment of the present invention also includes an MCU (Microcontroller Unit) 7. Figure 1 In the code, MIPICLK±, MIPID0±, MIPID1±, MIPID2±, and MIPID3± represent a pair of MIPI clock differential data corners. Similarly, MIPICKP and MIPICKN, MIPID0P and MIPID0N, MIPID1P and MIPID1N, MIPID2P and MIPID2N, and MIPID3P and MIPID3N also represent corresponding pairs of MIPI clock differential data corners; the only difference is the naming convention used by the two chips. RINO± represents the positive and negative corners of the serial data input. Likewise, SIOP and SION also represent positive and negative corners of the serial data input; the only difference is the naming convention used by the two chips.

[0056] The first GPIO (General-purpose input / output) interface 71 of MCU7 is connected to the second GPIO interface 21 of deserializer chip 2, and the first I2C (Inter-Integrated Circuit) interface 72 of MCU7 is connected to the second I2C interface 22 of deserializer chip 2.

[0057] The third GPIO interface 73 of MCU7 is connected to the fourth GPIO interface 31 of serializer chip 3, and the third I2C interface 74 of MCU7 is connected to the fourth I2C interface 32 of serializer chip 3. MCU7 can be an S32K1 series microcontroller.

[0058] Therefore, MCU7 controls the deserializer chip 2 through the first GPIO interface 71 and the first I2C interface 72, and controls the serializer chip 3 through the third GPIO interface 73 and the third I2C interface 74.

[0059] In one implementation, MCU7 has a memory unit.

[0060] Since the MCU7 has a storage unit, the configured software can be stored in the MCU7's storage unit, so that the configured software can be used every time it is powered on without manual intervention.

[0061] See also Figure 1 The data conversion device provided in this embodiment of the present invention also includes a power module 8 and a first power connector 9.

[0062] The first power connector 9 is electrically connected to the power module 8, and the power module 8 is electrically connected to the deserializer chip 2, the serializer chip 3, and the MCU7 respectively.

[0063] The first power connector 9 is used to connect to an external power supply. The power module 8 is used to convert the voltage value input from the first power connector 9 into the voltage value corresponding to the deserializer chip 2 and input it to the deserializer chip 2, convert the voltage value input from the first power connector 9 into the voltage value corresponding to the serializer chip 3 and input it to the serializer chip 3, and convert the voltage value input from the first power connector 9 into the voltage value corresponding to the MCU 7 and input it to the MCU 7.

[0064] Therefore, power is supplied to the deserializer chip 2, the serializer chip 3, and the MCU7 by setting up the power module 8 and the first power connector 9.

[0065] See also Figure 1 The power module 8 includes a first power chip 81 and a second power chip 82.

[0066] The first power chip 81 is electrically connected to the deserializer chip 2 and the serializer chip 3 respectively, and the second power chip 82 is electrically connected to the deserializer chip 2, the serializer chip 3 and the MCU7 respectively.

[0067] In this configuration, both the first power supply chip 81 and the second power supply chip 82 are MPQ2166 chips. For example, the voltage input to the first power connector 9 is 5V. The first power supply chip 81 converts the 5V voltage into 1.8V and 1.2V voltages required by the deserializer chip 2 and the serializer chip 3, respectively. The second power supply chip 82 converts the 5V voltage into 3.3V voltage required by the deserializer chip 2, the serializer chip 3, and the MCU 7.

[0068] Therefore, the first power supply chip 81 supplies power to the deserializer chip 2 and the serializer chip 3, and the second power supply chip 82 supplies power to the deserializer chip 2, the serializer chip 3 and the MCU7.

[0069] Figure 2 Another schematic diagram of the data conversion device provided in an embodiment of this utility model. See also Figure 2 The data conversion device provided in this embodiment of the present invention also includes a second power connector 10, a driver chip 11, and a first POC (Power Over Coaxia) circuit 12.

[0070] The fifth GPIO interface 75 of MCU7 is connected to the driver chip 11. The driver chip 11 is electrically connected to the second power connector 10 and the first coaxial power supply POC circuit 12. The first coaxial power supply POC circuit 12 is electrically connected to the FPD-Link video signal line 13. The FPD-Link video signal line 13 is the signal line between the first video connector 1 and the deserializer chip 2. For example, the driver chip 11 is a VN7140 chip.

[0071] The MCU7 monitors the power supply current of the driver chip 11 through the fifth GPIO interface 75. When the current is abnormal, it shuts off the driver chip 11 and stops supplying power, thereby achieving stable vehicle road testing or vehicle debugging. When the current is normal, it controls the driver chip 11 to supply power normally.

[0072] The driver chip 11, under the control of the MCU7, outputs the input voltage of the second power connector to the first coaxial power supply POC circuit. The first coaxial power supply POC circuit is used to superimpose the input voltage onto the FPD-Link video signal line to power the FPD-Link camera 5. For example, the input voltage of the second power connector is 8V.

[0073] Therefore, when the GMSL controller 6 outputs only a video signal, power can be supplied to the FPD-Link camera 5 that supports POC power supply by setting up the second power connector 10, the driver chip 11 and the first coaxial power supply POC circuit 12.

[0074] See also Figure 2 The data conversion device provided in this embodiment of the present invention also includes a second coaxial power supply POC circuit 14.

[0075] The voltage video signal line 15 is electrically connected to the second coaxial power supply POC circuit 14, and the second coaxial power supply POC circuit 14 is electrically connected to the FPD-Link video signal line 13. The voltage video signal line 15 is the signal line between the second video connector 4 and the serializer chip 3.

[0076] The second coaxial power supply POC circuit is used to superimpose the voltage output from the GMSL controller 6, received through the voltage video signal line 15, onto the FPD-Link video signal line to power the FPD-Link camera.

[0077] Therefore, when the GMSL controller 6 outputs both video signal and voltage, the voltage output by the GMSL controller 6 is superimposed onto the FPD-Link video signal line through the second coaxial power supply POC circuit to power the FPD-Link camera, thus achieving voltage separation and superposition without the need for an external power supply.
