[0002] In existing vehicles, the car computer screen will go black directly when the voltage of the entire vehicle is low or insufficient, resulting in voltage fluctuations. In scenarios where the car computer screen needs to be used, such as cold start, hot start, and vehicle driving, it is easy for users to mistakenly believe that the car computer is damaged and cause maintenance events. When the car computer is returned to the factory for repair, maintenance personnel need to spend a lot of time inspecting the car computer to find the cause of the screen failure, but most of the test results are not a failure of the car computer screen itself, resulting in a waste of resources.

Through the description of the specific embodiments, a deeper and more detailed understanding of the technical means and effects adopted by this application to achieve the intended purpose can be obtained. However, the accompanying drawings are provided for reference and illustration purposes only and are not intended to limit this application.

[0020] First embodiment

[0021] Figure 1 The flowchart of a method for processing screen abnormality provided by the first embodiment of the present invention is as follows. Figure 1 As shown, the method for handling screen abnormalities of this embodiment is applied to an electronic device and includes the following steps:

[0022] Step 210: monitor whether the power supply voltage meets the preset screen-on condition.

[0023] Among them, the screen is a screen installed on the electronic device or a screen controlled by the electronic device. The electronic device includes but is not limited to a car computer. The power supply voltage is the voltage of the power supply used by the screen. When the screen needs to be powered on or is in use, the power supply voltage is monitored, and then different control operations are performed on the screen according to the state of the power supply voltage to realize screen abnormal prompts and abnormal information recording.

[0024] The preset screen-on condition refers to a voltage condition preset in the electronic device that can meet the screen-on requirement. In this embodiment, step 210 monitors whether the power supply voltage meets the preset screen-on condition, which may specifically include the following steps:

[0025] Monitor whether the power supply voltage is continuously lower than a preset threshold or fluctuates within a preset range, and the upper limit of the preset range is greater than the preset threshold;

[0026] If the power supply voltage is continuously lower than the preset threshold or fluctuates within a preset range, it is determined that the power supply voltage does not meet the preset screen-on condition.

[0027] Among them, the preset threshold is preferably the lowest voltage that can satisfy the screen lighting condition. When the power supply voltage is continuously higher than the preset threshold, it is considered that the power supply voltage is sufficient and stable, and meets the preset screen lighting condition. At this time, the screen can be turned on and lit or maintain the current screen lighting state, and the screen works normally. On the contrary, when the power supply voltage is continuously lower than the preset threshold or fluctuates within the preset range, it is considered that the power supply voltage is insufficient or unstable, and does not meet the preset screen lighting condition. At this time, the screen cannot be turned on or cannot continue to light up normally, and the screen is confirmed to be abnormal. Usually, voltage fluctuations are prone to occur when the power supply voltage is low. In this embodiment, the preset interval is set to a voltage interval with an upper limit value greater than the preset threshold. When the power supply voltage fluctuates within this interval, it is in a critical state of screen lighting and screen off, which has monitoring significance.

[0028] Step 220: If the power supply voltage does not meet the preset screen-on condition, it is determined that the screen is abnormal, and whether the power supply voltage meets the abnormal start-up condition is determined.

[0029] If the power supply voltage does not meet the preset screen-on condition, it is determined that the screen is abnormal, and the process continues to determine whether the power supply voltage meets the abnormal startup condition. In this embodiment, determining whether the power supply voltage meets the abnormal startup condition includes the following steps:

[0030] If the power supply voltage fluctuates within a preset interval, when the power supply voltage fluctuates to a value greater than or equal to a preset threshold, it is determined that the power supply voltage meets the abnormal startup condition.

[0031] Because the preset interval is a voltage interval with an upper limit greater than a preset threshold, during the fluctuation of the power supply voltage within this interval, it will fluctuate to a value greater than or equal to the preset threshold within a short period of time, thereby satisfying the startup conditions within a short period of time and enabling startup. Because the startup conditions are met under abnormal voltage fluctuations, this application defines startup in this scenario as abnormal startup, which includes powering on under abnormal conditions and / or keeping the screen on under abnormal conditions.

[0032] Furthermore, when the power supply voltage fluctuates within a preset range and briefly falls below a preset threshold, the screen maintains its current operating state. This means the screen remains off when it needs to be powered on, and remains powered on when it's already powered on. If the power supply voltage remains below the preset threshold, the screen won't turn on, and the abnormal startup condition isn't met.

[0033] Step 230: If the power supply voltage meets the abnormal startup condition, the screen starts and displays an abnormal prompt;

[0034] Among them, when the power supply voltage meets the abnormal startup conditions, abnormal startup is performed, that is, the screen is turned on and on in the scenario where power is required, and the screen continues to be on in the scenario where the power is already on and displayed. At this time, although the screen is in an abnormal state, it is still displayed on the screen. At the same time, the power supply voltage status prompt and / or the prompt that the screen is about to be turned off is displayed on the screen. For example, it displays "The vehicle battery power is insufficient and will be turned off in 3 seconds. If the car computer needs to work normally, please charge or replace the battery", so that the user can timely understand the battery voltage status and the operation to be performed, and will not be affected by the failure to turn on the screen or the sudden black screen. The user experience will not be affected, or even a wrong perception of screen failure will be generated.

[0035] After an abnormal prompt is displayed, turn off the screen to avoid being in an abnormal startup state for a long time, which may cause damage to the screen.

[0036] Step 240: Record the serial port log information when the screen is in an abnormal state.

[0037] The log file outputs some program status during software operation. When the screen starts abnormally, the serial port log information under the abnormal screen state is recorded. This serial port log information records abnormal information such as the fluctuation of the power supply voltage and the abnormal startup duration of the screen.

[0038] In addition, if the power supply voltage does not meet the abnormal startup conditions, the screen will not be started but the step of recording the serial port log information under the abnormal state of the screen will still be executed. For example, if the power supply voltage is continuously lower than the preset threshold and does not meet the abnormal startup conditions, the screen will not be started and the step of recording the serial port log information under the abnormal state of the screen will be executed. The recorded serial port log information may include abnormal information such as the current power supply voltage and the display status of the screen.

[0039] Serial port log information can be directly accessed by connecting the electronic device to a storage device such as a USB flash drive, or uploaded online via voice commands, such as to an analysis device or the cloud. When uploading online via voice commands, the electronic device receives the voice command to upload the serial port log information and, in response, sends the serial port log information to the designated destination. Maintenance personnel can quickly analyze the cause of screen anomalies by viewing the serial port log information, improving maintenance efficiency.

[0040] Next, combine Figure 2 The specific processing flow of this embodiment is described. When the screen needs to be powered on or is in use, the power supply voltage is obtained for monitoring. First, it is determined whether the power supply voltage is continuously lower than a preset threshold, and whether the power supply voltage fluctuates within a preset range, and the upper limit of the preset range is greater than the preset threshold.

[0041] If it is determined that the power supply voltage is not continuously lower than the preset threshold, the obtained voltage power supply is further determined to be continuously lower than the preset threshold. In this case, the preset screen-on condition is met, and the screen can be turned on or kept on. Conversely, if it is determined that the power supply voltage is continuously lower than the preset threshold, neither the preset screen-on condition nor the abnormal startup condition is met, and the step of recording the serial port log information of the abnormal screen state is executed.

[0042] If it is determined that the power supply voltage fluctuates within the preset range, it is further determined whether the power supply voltage fluctuates to a value greater than or equal to the preset threshold value. If it is determined that the power supply voltage does not fluctuate to a value greater than or equal to the preset threshold value, it is further determined whether the obtained voltage power supply fluctuates within the preset range. At this time, the current working state of the screen is maintained, that is, in the scenario where power is required, the screen is kept in the off state, and in the scenario where the screen is already powered on and displayed, the screen is kept in the powered on state. Conversely, if it is determined that the power supply voltage fluctuates to a value greater than or equal to the preset threshold value, the preset screen-on condition is not met but an abnormal startup can be performed. At this time, the screen is started, including turning on the screen in the scenario where power is required and keeping the screen on in the scenario where the screen is already powered on and displayed. At the same time, an abnormal prompt is displayed, and the serial port log information under the abnormal state of the screen is recorded.

[0043] The processing method of this application can support the screen to light up when the screen is in an abnormal state, provide abnormal prompts, and at the same time, record serial port log information in combination with different power supply voltage states, which is more targeted. By integrating abnormal reminders with abnormal information records, users can gain intuitive perception, avoid the misperception of screen failures, reduce the fault reporting rate, improve maintenance efficiency, and comprehensively enhance the experience of all types of people around screen products while reducing costs.

[0044] The screen abnormality handling method of this embodiment monitors whether the power supply voltage meets the preset screen-on conditions. If the power supply voltage does not meet the preset screen-on conditions, the screen is determined to be abnormal and the power supply voltage is determined to meet the abnormal startup conditions. If the power supply voltage meets the abnormal startup conditions, the screen is powered on and an abnormality prompt is displayed. The serial port log information during the screen abnormality is recorded. In this way, a prompt is displayed when the screen is abnormal, which improves the user experience. At the same time, the recorded abnormality information can be used to analyze the cause of the fault, thereby improving maintenance efficiency.
