[0015] The embodiments of this invention provide a video protocol conversion method for vehicle-mounted terminals, such as... Figure 2 As shown, this method is applied to the controller 111 of an in-vehicle terminal. The in-vehicle terminal includes a host 11 and a display screen 12. The host includes a controller 111, a conversion chip 112, and an output chip 113. The display screen 12 has an input signal interface. The controller 111 communicates with the conversion chip 112, the output chip 113, and a register. The conversion chip 112 also communicates with the output chip 113. The output terminal of the output chip 113 is connected to the input signal interface of the display screen 12. The conversion chip 112, the output chip 113, and the register corresponding to the conversion chip 112 constitute a conversion component. This video protocol conversion method is executed by application software installed in the controller 111. The controller 111 is a SoC chip used for output control. The controller 111 can output the video signal to be displayed and transmit it to the conversion component. The conversion component converts the video signal to obtain a video conversion signal and outputs it to the display screen for display. The controller 111 can also receive data information from the conversion component for processing and send corresponding control commands to each component in the conversion component to control each component in the conversion component.

[0016] like Figure 1 As shown, the method includes steps S110 to S150.

[0017] S110: Receive the power-on signal, detect the video signal output, and set the signal output status parameters accordingly based on the detection results.

[0018] When the vehicle is powered on, the controller receives the power-on signal and initiates the DPI (Display Pixel Interface) signal output process. At this time, the signal output status parameter is set to an anomaly check state, corresponding to the status code "INIT_FLAG_CHECK". If this process runs normally, it outputs the corresponding DPI signal, which is also the video signal. The controller performs output detection on the video signal, that is, it determines whether the output DPI signal meets the preset signal output requirements and obtains the corresponding detection results. For example, it checks whether there is a DPI signal output, whether the pixel data format of the output DPI signal matches the standard format set in the signal output requirements, and whether the pixel clock of the output DPI signal corresponds to the default pixel clock set in the signal output requirements. If a DPI signal is output and all parameters of the output DPI signal meet the signal output requirements, the detection result is that the DPI signal output is normal. If there is no DPI signal output, or if any parameter of the output DPI signal does not meet the signal output requirements, the detection result is that the DPI signal output is abnormal.

[0019] If the detection result indicates that the signal output is normal, the corresponding signal output status parameter is set to the first preset output status, and the status code is “INIT_FLAG_START”. If the detection result indicates that the signal output is abnormal, the corresponding signal output status parameter is set to the second preset output status, and the status code is “INIT_FLAG_CHECK”. When the signal output status parameter is set to the second preset output status, the display screen continuously displays black, thereby avoiding problems such as white screen, distorted screen, or flickering screen caused by no signal or abnormal signal during power-on.

[0020] S120. If the signal output state parameter is the first preset output state, initialize the conversion component.

[0021] If the signal output status parameter is the first preset output status, the conversion component is initialized, thereby putting the conversion component into a ready state.

[0022] In a specific embodiment, step S120 includes the following sub-steps: powering on the conversion component according to a preset power-on sequence; and initializing the registers corresponding to the conversion component.

[0023] Specifically, the power-on control of the components included in the conversion assembly is performed according to the preset power-on sequence. The power-on order of the conversion chip, output chip and the register corresponding to the conversion chip is controlled in sequence according to the power-on sequence. If the power-on sequence is register, output chip and conversion chip, then the register, output chip and conversion chip are powered on in sequence according to the power-on sequence.

[0024] Furthermore, the registers corresponding to the conversion component are initialized. Specifically, the stored information in the registers can be zeroed out, thereby initializing the registers.

[0025] S130. Detect the working status of the conversion component and set the working status parameters accordingly.

[0026] Further, the working status of the conversion component is detected, and the working status parameters are set accordingly based on the detection results.

[0027] In a specific embodiment, step S130 includes the following sub-steps: after initialization, the working state parameter is set to the power-on state; after setting to the power-on state and a first delay, it is determined whether the state of the conversion component is stable; if the state of the conversion component is stable, the working state parameter is set to the stable state; after setting to the stable state and a second delay, it is determined whether the working state of the conversion component is normal; if the working state of the conversion component is normal, the working state parameter is set to the normal working state.

[0028] After initialization, the operating status parameter can be set to the power-on state, at which point the status code is "POWER_ON". After setting to the power-on state and waiting for the first delay (which can be set to 10ms), proceed to the next step. After setting to the power-on state, determine whether the conversion component is stable, that is, whether the conversion chip and output chip in the conversion component are working stably. Specifically, read the corresponding status parameters from the conversion chip and output chip of the conversion component respectively, and determine whether the status parameters of the conversion chip and output chip are consistent with the preset status parameters. If the status parameters of the conversion chip and output chip are consistent with the preset status parameters, it indicates that the conversion component is in a stable operating state; if the status parameters of the conversion chip or output chip are inconsistent with the preset status parameters, it indicates that the conversion component is not in a stable operating state.

[0029] If both the conversion chip and the output chip are in a stable state, the conversion component is determined to be stable, and the operating status parameter is set to stable state. At this time, the corresponding status code is "WORK_CHECKVIDEO_PRE". After being set to stable state and after a second delay, the process proceeds to the next step. For example, the second delay can be set to 10ms.

[0030] Furthermore, after a second delay, the operating status of the conversion component is determined, at which point a pre-detection state is entered. The power supply signals of the conversion chip and output chip, as well as the status information of the registers, are acquired. It is determined whether the power supply signals of the conversion chip and output chip match preset signal values, and whether the status information of the registers matches preset register status parameters. If the power supply signals of both the conversion chip and output chip match the preset signal values, it indicates that the power supply to the conversion chip and output chip is normal. If the power supply signal of a component does not match the preset signal value, it indicates that the power supply to that component is abnormal. If the status information of the register matches the preset register status parameters, it indicates that the register status is normal. If the status parameters of the register do not match the preset register status parameters, it indicates that the register status is abnormal. If the power supply to the conversion chip and output chip is normal and the register status is normal, the operating status of the conversion component is determined to be normal; otherwise, the operating status of the conversion component is determined to be abnormal.

[0031] If the conversion component is working normally, the working status parameter is set to normal working state, and the corresponding status code is "WORK_CHECKVIDEO_VALUE". After setting the normal working state and after the third delay, the subsequent steps are entered, that is, step S140 is entered. The third delay can be 10ms.

[0032] S140. If the working status parameter is in normal working state, perform a consistency check on the input data received by the conversion component to obtain a consistency check result indicating whether it is normal.

[0033] If the working status parameter is the first preset working status, then the input data received by the conversion component is subjected to consistency detection, and the corresponding consistency detection result is obtained; the consistency detection result can be normal or abnormal.

[0034] In a specific embodiment, step S140 includes the following sub-steps: determining whether each data item in the input data is consistent with a preset detection value; if each data item is consistent with the detection value, a normal consistency detection result is obtained; if a data item is inconsistent with the detection value, determining whether the error value between the data item and the detection value is within a preset error range; if the error value corresponding to the data item is within the error range, a normal consistency detection result is obtained; if the error value corresponding to any data item is not within the error range, an abnormal consistency detection result is obtained.

[0035] The input data includes multiple data items, such as vfp, vact, vtotal, hfp, hact, and htotal in the input data received by the conversion component; each data item corresponds to a row data value, and it can be determined whether the row data value of each data item is consistent with the preset detection value; the preset detection value can be the number of pixel rows.

[0036] If the row data value of each data item is consistent with the detection value, it indicates that the input data is correct, that is, each data item in the input data is consistent with the preset detection value and there is no error; then the consistency detection result of normal detection is obtained.

[0037] If the row data value of a certain data item does not match the detected value, it indicates that there may be electromagnetic interference or electrostatic interference, causing the row synchronization signal to be lost (i.e., row dropping). In this case, the error value between the row data value and the detected value of the data item can be further obtained, and it can be determined whether the error value is within a preset error range. Specifically, the row data value of each data item can be obtained, and the absolute value of the difference between each row data value and the detected value can be calculated as the error value corresponding to each row data value; then each row data value can be assigned an error value. It is determined whether the error values ​​of each row data value are within the error range, for example, the error range can be set to [0, 2]. If the error values ​​corresponding to each data item are within this error range, a normal consistency detection result is obtained, and the row error is within an acceptable range; if the error value corresponding to a certain data item is not within this error range, an abnormal consistency detection result is obtained.

[0038] S150. If the consistency detection result is normal, output the video conversion signal obtained by the conversion component.

[0039] If the consistency check result is normal, the set working status parameters are maintained in the normal working state, and the corresponding status code is "WORK_CHECKVIDEO_VALUE". The video conversion signal obtained by the conversion component is output, which is also the LVDS (Low-Voltage Differential Signaling) signal. After receiving the video conversion signal, the display screen can display the corresponding image.

[0040] In a specific embodiment, after step S150, the method further includes the step of: after a preset loop time interval, returning to the step of performing consistency detection on the input data received by the conversion component to obtain a consistency detection result indicating whether it is normal.

[0041] Furthermore, after step S150, the conversion component continues to receive input data and perform protocol conversion, while the display screen continues to display the image. At this time, the input data received by the conversion component can also be cyclically checked; after a preset cyclic time interval, the process returns to the step of performing a consistency check on the input data received by the conversion component to obtain a consistency check result, i.e., returning to step S140. The cyclic time can be set to 2000ms.

[0042] In a specific embodiment, after step S140, the method further includes the following steps: if the consistency detection result is not normal, set the signal output status parameter to an abnormal check state; after a preset detection interval time, return to the step of detecting the video signal output and setting the signal output status parameter accordingly based on the detection result.

[0043] If the consistency detection result is abnormal, the signal output status parameter is set to an abnormal check state, and the corresponding status code is "INIT_FLAG_CHECK". After a preset detection interval, the process returns to the step of detecting the video signal output and setting the signal output status parameter according to the detection result, that is, returning to step S110 and re-executing the above steps; for example, the detection interval can be set to 10ms.

[0044] In a specific embodiment, after step S110, the method further includes the step of: if the signal output state parameter is not the first preset output state, after a preset cycle detection time, performing the step of detecting the video signal output and setting the signal output state parameter accordingly based on the detection result again.

[0045] If the signal output status parameter is not the first preset output state, it indicates that the controller's signal output is abnormal. In this case, after a preset loop detection time, the step of detecting the video signal output and setting the signal output status parameter according to the detection result can be executed again, that is, step S110 can be executed again. The loop detection time can be set to 20ms. That is, step S120 is only executed when the signal output status parameter is the first preset output state; otherwise, step S110 is executed repeatedly to continuously detect the video signal output.

[0046] The video protocol conversion method for an in-vehicle terminal disclosed in the above embodiments includes: receiving a power-on signal; detecting the video signal output and setting signal output status parameters accordingly based on the detection result; if the signal output status parameters are a first preset output state, initializing the conversion component; detecting the working state of the conversion component and setting working state parameters accordingly; if the working state parameters are a first preset working state, performing a consistency detection on the input data received by the conversion component to obtain a consistency detection result indicating whether it is normal; if the consistency detection result is normal, outputting the video conversion signal obtained by the conversion component. The above video protocol conversion method for an in-vehicle terminal, by detecting the video signal output and the input data, ensures that the conversion component can properly process video stream format conversion and enables anomaly troubleshooting and process restart to resolve various abnormal situations.

[0049] The first detection unit 110 is used to receive the power-on signal, detect the video signal output, and set the signal output status parameters accordingly based on the detection results.

[0050] The initialization unit 120 is used to initialize the conversion component if the signal output state parameter is a first preset output state.

[0051] The second detection unit 130 is used to detect the working status of the conversion component and set the working status parameters accordingly.

[0052] The third detection unit 140 is used to perform consistency detection on the input data received by the conversion component to obtain a consistency detection result indicating whether the working status parameter is in normal working state.
