Technical Field

[0001] The present application relates to the technical field of aviation industry, and in particular to a method and device for controlling an airborne display screen compatible with day and night. Background Art

[0002] With the development of the aviation industry and the advancement of technology, modern commercial and military aircraft are increasingly relying on advanced avionics systems to improve flight efficiency and safety. In these systems, the onboard display screen is the key interface for pilots to obtain flight information, and its performance directly affects the pilot's operational accuracy and reaction speed.

[0003] Traditional airborne display screens usually use fixed brightness settings, which may not meet reading needs under certain conditions. Although some display screens with automatic adjustment functions can solve this problem to a certain extent, due to the involvement of complex sensors and control systems, there is a risk of accidental adjustments due to malfunctions, which poses a potential threat to flight safety.

[0004] From the above, it can be seen that how to ensure that it can adapt to various lighting conditions and ensure high operational reliability still needs to be solved. Summary of the invention

[0005] In order to adapt to various lighting conditions and ensure operational reliability, the present application provides a day-and-night compatible airborne display screen control method and device.

[0006] In a first aspect, the present application provides a day-night compatible airborne display screen control method, which adopts the following technical solution: A day-night compatible airborne display screen control method comprises: continuously acquiring corresponding illumination information based on a photosensitive element installed in a cockpit, converting the illumination information into corresponding illumination intensity data, and determining a corresponding illumination intensity data set, wherein the illumination intensity data is a digital signal, and each illumination intensity data corresponds to a timestamp; determining the current corresponding time period data, determining the average illumination intensity data corresponding to each time period based on the illumination intensity data set and the time period data, retrieving the illumination threshold corresponding to the time period data, and comparing the average illumination intensity data with the illumination threshold; if the average illumination intensity data is greater than the illumination threshold, determining that the illumination condition has changed, and prompting the driver to adjust the brightness by playing voice data in the cockpit, and judging whether the display screen brightness adjustment is completed after receiving feedback data after the driver manually adjusts the mechanical button.

[0007] By adopting the above technical solution, the photosensitive element can monitor the lighting conditions inside and outside the cockpit in real time to ensure timely response to environmental changes. By analyzing and processing the light intensity data, the system can accurately judge the changes in lighting conditions and avoid false alarms; and remind the pilot to make manual adjustments through voice prompts, which improves the intuitiveness and convenience of human-computer interaction. It should be pointed out that all adjustment actions need to be manually executed and confirmed by the pilot, avoiding the risk of failure of the automated control system and ensuring flight safety.

[0008] Optionally, in the process of determining whether the display screen brightness adjustment is completed, the method also includes: obtaining a current brightness parameter corresponding to the display screen after adjustment by the driver; retrieving the brightness adjustment parameter corresponding to the display screen in the voice data; matching the current brightness parameter with the brightness adjustment parameter, and if they match, determining that the driver has made a manual adjustment, and being responsible for repeatedly playing the voice data for prompting.

[0009] By adopting the above technical solution, by comparing the current brightness parameters with the recommended brightness parameters, the system can accurately determine whether the pilot has completed the required brightness adjustment; and if the pilot has not adjusted correctly or has not completed the adjustment, the system can remind the pilot by repeatedly playing voice prompts, thereby avoiding poor display effects caused by misoperation.

[0010] Optionally, in the process of converting the lighting information into corresponding lighting intensity data, the method also includes: obtaining the current ambient temperature in the cockpit, and retrieving a preset temperature-light relationship table for the photosensitive element; calculating the actual sensitivity of the photosensitive element at the current ambient temperature based on the current ambient temperature and the temperature-light relationship table; and correcting the original light intensity reading based on the actual sensitivity and generating temperature-compensated light intensity data.

[0011] By adopting the above technical solution, the sensitivity of the photosensitive element will change with temperature. Temperature compensation can eliminate this effect and ensure the accuracy of the light intensity reading. It can also accurately detect light intensity under different temperature conditions and is suitable for various flight environments. Even during long-term use, the aging or performance degradation of the photosensitive element caused by temperature changes can be effectively compensated.

[0012] Optionally, the method also includes: retrieving the currently corresponding light intensity data, retrieving a preset light intensity and color temperature correspondence table; calculating corresponding screen color temperature data based on the light intensity data and the light intensity and color temperature correspondence table; and adjusting the color temperature of the display screen based on the screen color temperature data.

[0013] By adopting the above technical solution, the color temperature setting of the display screen can be automatically optimized according to the ambient light conditions. This can not only improve the visual comfort of the display screen under different lighting conditions (for example, using warm colors at night to reduce the impact of blue light on the eyes, and using cool colors during the day to improve clarity), but also reduce the operating burden of the pilot, ensuring the best readability of the information display and the visual health of the pilot.

[0014] Optionally, the method also includes: calling the corresponding light intensity data set, arranging all the light intensity data in the light intensity data set in time series, and obtaining a corresponding light intensity arrangement diagram; calculating the light change rate corresponding to the light intensity based on the light intensity arrangement diagram; and predicting the corresponding light change trend based on the light change rate and time series.

[0015] By adopting the above technical solution, by retrieving the light intensity data set and merging it into a time series arrangement, generating a light intensity arrangement diagram, calculating the rate of change of light intensity, and predicting the future light change trend based on the change rate and time series, changes in ambient light conditions can be predicted in advance; it not only helps the system to adjust the display brightness and other parameters more smoothly, but also can notify the pilot in advance to make necessary manual adjustments, thereby improving the system's response speed and the pilot's operating efficiency, and ensuring that the display always provides the best visual effect under different lighting conditions.

[0016] Optionally, after acquiring the light intensity data, the method further includes: retrieving corresponding extreme light data, matching the light intensity data with the extreme light data to determine whether it is an extreme light condition; if the match is an extreme light condition, controlling the display screen to automatically switch to a preset safety mode; after switching to the safety mode, informing the pilot that the safety mode has been entered by playing a pre-recorded prompt message.

[0017] By adopting the above technical solution, the obtained light intensity data is compared with the preset extreme light data to identify whether it is in extreme light conditions. If it is identified as an extreme situation, the display screen will automatically switch to safety mode, and the pilot will be notified that the safety mode has been entered by playing a pre-recorded prompt message, thereby ensuring that clear and visible information display can still be provided under extreme light conditions to ensure the safety of flight operations.

[0018] In a second aspect, the present application provides a day-night compatible airborne display screen control device, which adopts the following technical solution: A day-night compatible airborne display screen control device, comprising: A light information acquisition module, based on a photosensitive element installed in the cockpit, is used to continuously acquire corresponding light information, convert the light information into corresponding light intensity data, and determine a corresponding light intensity data set, wherein the light intensity data is a digital signal, and each light intensity data corresponds to a timestamp; A light intensity comparison module determines the current corresponding time period data, determines the average light intensity data corresponding to each time period based on the light intensity data set and the time period data, and retrieves the light threshold corresponding to the time period data to compare the average light intensity data with the light threshold; The judgment module determines that the lighting conditions have changed if the average light intensity data is greater than the light threshold, and plays voice data in the cockpit to prompt the driver to adjust the brightness. The feedback data received after the driver manually adjusts the mechanical button is used to determine whether the display brightness adjustment is completed. In a third aspect, the present application provides a day-night compatible airborne display screen control method, which adopts the following technical solution: A day-night compatible onboard display screen control method comprises a processor, wherein the processor runs a program of any one of the day-night compatible onboard display screen control methods described above.

[0021] Figure 1 The present invention is a flow chart showing a method for controlling a day-night compatible onboard display screen according to an exemplary embodiment.

[0022] Figure 2 The present invention is a structural block diagram of a day-night compatible onboard display screen control method and device according to an exemplary embodiment. DETAILED DESCRIPTION

[0023] Embodiments of the present application are described in detail below, examples of which are shown in the accompanying drawings.

[0024] In the description of this specification, the description with reference to the terms "certain embodiments", "one embodiment", "some embodiments", "illustrative embodiments", "examples", "specific examples", or "some examples" means that the specific features, structures, materials, or characteristics described in conjunction with the embodiments or examples are included in at least one embodiment or example of the present application. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0025] The present application embodiment discloses a day and night compatible onboard display screen control method, referring to Figure 1 ,include: S100, continuously acquiring corresponding illumination information based on a photosensitive element installed in the cockpit, converting the illumination information into corresponding illumination intensity data, and determining a corresponding illumination intensity data set.

[0026] Highly sensitive photosensitive elements (such as photodiodes or photoresistors) are installed at appropriate locations in the cockpit, and these photosensitive elements monitor the lighting conditions inside and outside the cockpit in real time and convert analog signals into digital signals; each light intensity data is timestamped for subsequent time series analysis, and the collected light intensity data and its corresponding timestamp are stored in the system's memory or database.

[0027] By collecting light intensity data, we can ensure that the system can respond to changes in ambient light in a timely manner and provide an accurate and continuous data source for subsequent data processing and analysis.

[0028] S110, determine the current corresponding time period data, determine the average light intensity data corresponding to each time period based on the light intensity data set and the time period data, retrieve the light threshold corresponding to the time period data, and compare the average light intensity data with the light threshold.

[0029] Among them, a day is divided into multiple time periods (for example, each 10 minutes is a time period), and all light intensity data in each time period are statistically analyzed to calculate the average light intensity in the time period. By calculating the average value, the impact of instantaneous fluctuations can be reduced and the stability of the data can be improved.

[0030] It should be pointed out here that the light thresholds for different time periods are preset. These light thresholds are set based on experimental data and experience to distinguish different lighting conditions (such as daytime, dusk, and night). The average light intensity of each time period is compared with the preset light threshold. By comparing the average light intensity with the threshold, the changes in lighting conditions can be accurately judged to avoid false alarms.

[0031] S120, if the average light intensity data is greater than the light threshold, it is determined that the light condition has changed, and the driver is prompted to adjust the brightness by playing voice data in the cockpit. After receiving feedback data after the driver manually adjusts the mechanical button, it is determined whether the display brightness adjustment is completed.

[0032] Among them, if the average light intensity is greater than the preset light threshold, it can be determined that the light conditions have changed, and voice prompt information can be generated through speech synthesis technology. The voice prompt is played through the speaker or headphones in the cockpit to inform the pilot that the current light conditions have changed and it is recommended to adjust the brightness. It should be pointed out here that through voice prompts, the pilot can immediately know the changes in light conditions and improve the response speed.

[0033] In addition, the pilot finds and operates the corresponding mechanical buttons according to the voice prompts to gradually adjust the brightness of the display screen. After the pilot completes the adjustment, he can confirm the completion of the operation by pressing a button again or in other ways. After receiving the pilot's confirmation signal, the system records the current brightness setting and turns off the voice prompt. In the embodiment of the present application, all adjustment actions need to be manually performed and confirmed by the pilot, avoiding the risk of failure of the automated control system and ensuring flight safety. The system ensures that the adjustment operation has been completed by receiving the pilot's manual confirmation signal, forming a corresponding feedback mechanism, thereby improving the reliability and accuracy of the system.

[0034] Through the above steps, real-time monitoring of lighting conditions inside and outside the cockpit can be achieved, and voice prompts can be automatically triggered according to changes in lighting conditions to guide the pilot to manually adjust the brightness; this not only improves the response speed and reliability of the system, but also enhances the intuitiveness and convenience of human-computer interaction, ensuring that the display screen always provides a clear and easy-to-read display effect under different lighting conditions, thereby ensuring the safety and efficiency of flight operations.

[0035] It should be noted here that, in the process of determining whether the display brightness adjustment is completed, the method further includes: S121, obtaining the current brightness parameter of the display screen after adjustment by the driver.

[0036] The system reads the current brightness setting value from the display controller and records the timestamp of the current brightness parameter to ensure that the system can obtain the latest brightness setting adjusted by the pilot.

[0037] S122, retrieve the brightness adjustment parameter corresponding to the display screen in the voice data.

[0038] The suggested brightness adjustment parameters are extracted from the voice prompt module and stored in the system memory to facilitate comparison with the actual brightness parameters.

[0039] S123, matching the current brightness parameter with the brightness adjustment parameter, if they match, it is determined that the driver has made manual adjustment, and the driver is responsible for repeatedly playing the voice data for prompting.

[0040] Among them, if the current brightness parameter is consistent with the recommended brightness parameter or is within the allowable error range, the match is considered successful; by comparing the current brightness parameter with the recommended brightness parameter, the system can accurately determine whether the pilot has completed the required brightness adjustment.

[0041] In addition, if the current brightness parameter matches the recommended brightness parameter, it means that the pilot has made the correct manual adjustment according to the prompt, and then the voice prompt can be turned off and the adjustment result and timestamp can be recorded; it should be pointed out here that if the current brightness parameter does not match the recommended brightness parameter, the system will repeatedly play the voice prompt to remind the pilot to continue to adjust the brightness, and a short time interval can be set between each repeated prompt to avoid interference caused by frequent prompts. Through multiple prompts, the poor display effect caused by misoperation can be reduced, thereby improving the reliability and safety of the system.

[0042] During the operation of the photosensitive element, the influence of the environment on the photosensitive element needs to be considered. In the process of converting the light information into the corresponding light intensity data, the present application scheme also performs the following steps: S101, obtaining the current ambient temperature in the cockpit and retrieving a temperature-light relationship table preset by a photosensitive element.

[0043] Among them, it is necessary to install temperature sensors at appropriate locations inside and outside the cockpit in advance. The temperature sensors can monitor the ambient temperature in the cockpit in real time and transmit the collected temperature data to the control unit or processor. The system pre-stores a temperature-light relationship table of the photosensitive element. The temperature-light relationship table describes the response characteristics of the photosensitive element at different temperatures, so that the corresponding parameters can be called up based on the temperature-light relationship table according to the current ambient temperature.

[0044] S102, calculating the actual sensitivity of the photosensitive element under the current ambient temperature based on the current ambient temperature and the temperature-light relationship table.

[0045] Among them, by using the current ambient temperature and the data in the temperature-light relationship table, the actual sensitivity of the photosensitive element at the current temperature is calculated through interpolation or other mathematical methods. Specifically, the calculation method can be linear interpolation, polynomial fitting, etc., depending on the data format and accuracy requirements of the relationship table; and the actual sensitivity of the photosensitive element at the current ambient temperature is obtained through calculation, which can provide key parameters for correcting the light intensity reading.

[0046] S103, correcting the original light intensity reading based on the actual sensitivity and generating temperature-compensated light intensity data.

[0047] Among them, the original light intensity reading is corrected by the actual sensitivity, so that the light intensity data after temperature compensation can be generated. By correcting the original light intensity reading, the influence of temperature change on the sensitivity of the photosensitive element is eliminated, the accuracy of the light intensity data is ensured, and no matter how the ambient temperature changes, the system can provide consistent and reliable light intensity data, which is suitable for various flight environments. Even during long-term use, the aging or performance degradation of the photosensitive element caused by temperature changes can be effectively compensated, extending the service life of the system.

[0048] By executing steps S101 to S103, the influence of ambient temperature on the photosensitive element can be considered and temperature compensation can be performed in the process of converting the illumination information into illumination intensity data, which not only improves the accuracy of the illumination intensity data but also enhances the adaptability and reliability of the system.

[0049] And when adjusting the brightness of the display, the color temperature of the display needs to be considered for the driver to see, so the following steps are also performed: S1201, retrieve current corresponding light intensity data, and retrieve a preset light intensity and color temperature correspondence table.

[0050] The current light intensity data is obtained from the system memory or database and is timestamped to ensure that the data is up to date to reflect the current actual light conditions.

[0051] In addition, the system pre-stores a table of correspondence between light intensity and color temperature, which describes the recommended screen color temperature values ​​under different light intensities. According to the current light intensity data, the corresponding color temperature parameters can be quickly obtained to facilitate subsequent calculations.

[0052] S1202, calculating corresponding screen color temperature data based on the light intensity data and a light intensity-color temperature correspondence table.

[0053] Among them, using the current light intensity data and the preset light intensity and color temperature correspondence table, the recommended screen color temperature under the current lighting conditions can be calculated through interpolation method, ensuring that the color temperature of the display matches the current lighting conditions and improving visual comfort.

[0054] S1203: Adjust the color temperature of the display screen based on the screen color temperature data.

[0055] Among them, the display controller adjusts the color temperature setting of the display according to the received color temperature data. By automatically adjusting the color temperature of the display, it ensures that the display effect is always optimal under different lighting conditions. For example, warm colors are used at night to reduce the impact of blue light on the eyes, and cool colors are used during the day to improve clarity, thereby improving the visual comfort of the pilot.

[0056] In order to make it easier to adjust the brightness of the onboard display, the following steps are also performed: S124, retrieve the corresponding light intensity data set, arrange all the light intensity data in the light intensity data set in time series, and obtain a corresponding light intensity arrangement diagram.

[0057] Among them, all light intensity data within a period of time are obtained from the system memory or database, and the light intensity data are sorted according to timestamps to generate time series data. Chart tools (such as line charts) can be used to visualize the time series data to generate a light intensity distribution diagram. The light intensity distribution diagram graphically displays the change of light intensity over time, which is convenient for intuitively observing the trend of lighting conditions.

[0058] S125, calculating the illumination change rate corresponding to the illumination intensity based on the illumination intensity arrangement diagram.

[0059] Among them, by calculating the difference in light intensity between two adjacent time points, the light intensity difference can be divided by the time interval to obtain the rate of change of light intensity; it should be pointed out here that by calculating the rate of change, the system can promptly detect the sudden change in lighting conditions and take corresponding adjustment measures.

[0060] S126, predicting the illumination change trend corresponding to the illumination change rate and the time series.

[0061] Among them, the time series analysis method is used to predict the future light change trend based on the historical light intensity data and the current change rate. The time series analysis method can adopt moving average. Through the corresponding prediction results, the display brightness and other parameters can be adjusted in advance, or the pilot can be prompted to make manual adjustments.

[0062] By executing steps S124 to S126, it is possible to predict future illumination change trends under different illumination conditions based on historical data and the current change rate, thereby adjusting the display brightness and other parameters in advance.

[0063] The driver may encounter extreme lighting conditions while driving, so the following steps are also performed: S104, after obtaining the light intensity data, retrieve the corresponding extreme light data, and match the light intensity data with the extreme light data to determine whether it is an extreme light condition.

[0064] Among them, extreme light data is usually pre-set and may be determined based on safety standards, equipment performance limits and user experience research. Extreme light data defined as "extreme" is extracted from the system database or preset parameters. Extreme light data may include very high light intensity (such as direct sunlight) and very low light intensity (such as complete darkness or thick fog).

[0065] In addition, the light intensity data collected in real time is compared with the threshold in the retrieved extreme light data. If the current light intensity exceeds the preset high threshold or is lower than the preset low threshold, it is considered to be an extreme light condition.

[0066] S105: If the lighting conditions are extreme, the control display automatically switches to a preset safety mode.

[0067] Among them, when extreme lighting conditions are detected, the system automatically triggers the display screen to switch to safety mode. It should be pointed out that in the embodiment of the present application, the safety mode may include adjusting the screen brightness, changing the display color scheme (such as using a black and white interface with higher contrast), simplifying the user interface to reduce interference, etc., and this transition is usually seamless and rapid to avoid unnecessary distraction to the pilot.

[0068] S106, after switching to the safety mode, the pilot is informed that the safety mode has been entered by playing a pre-recorded prompt message.

[0069] Among them, once the display screen enters the safety mode, the system will play a pre-recorded sound or text prompt message to inform the pilot that the current display has been adjusted to the safety mode, and the prompt can be a voice broadcast, pop-up window or other form of notification.

[0070] By executing steps S104 to S106, the readability and usability issues of the display screen under extreme lighting conditions can be effectively addressed, which not only improves the pilot's work efficiency but also greatly enhances the safety during flight.
