Description

Technical Field

[0001] This application relates to the technical field of brightness adjustment, and more specifically, to a method, device, equipment, and storage medium for automatically adjusting the brightness of a ship terminal. Background Art

[0002] Modern ship cabins usually contain a large number of electronic device terminals. These electronic device terminals generally include parts such as a display module, a control module, a service processing module, and a structural member. Among them, both the display module and the control module contain light-emitting components for providing interface display and operation prompt functions. The visibility of these light-emitting components under different ambient light conditions directly affects the user's operation experience and communication efficiency. The ambient light intensity range in the cabin is very wide. If the brightness adjustment is not timely or too drastic, it may cause visual discomfort or operation errors for the crew.

[0003] Currently, traditional dimming methods mostly adopt manual dimming or segmented dimming. During manual dimming, the crew manually adjusts the brightness of the light-emitting components through buttons or menus on the terminal, and can flexibly adjust the brightness according to personal preferences or the current ambient light conditions. During segmented dimming, the ambient light intensity is divided into several intervals, and each interval corresponds to a fixed brightness value. When the ambient light intensity changes, the system switches the brightness according to the preset intervals, and can adapt to the light change to a certain extent.

[0004] However, the current methods of manual dimming or segmented dimming cannot meet the environmental requirements of the cabin where the light changes drastically. Manually adjusting the brightness depends on the user's subjective judgment, the operation is cumbersome and prone to errors, and the uneven or frequent jumping of the brightness adjustment in the segmented dimming mode may cause visual discomfort to the user and cannot accurately adapt to complex light conditions. Therefore, there is an urgent need for an adaptive dimming method that can automatically adjust the brightness of the terminal light-emitting components according to the ambient light intensity to ensure that the terminal can maintain good visibility under different light conditions.

[0044] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0045] The terms "first", "second", "third", etc. in the specification and claims of this application and the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but optionally further includes steps or units not listed, or optionally further includes other steps or units inherent to these processes, methods, products or devices.

[0046] The present invention provides a method, device, equipment and storage medium for automatically adjusting the brightness of a ship terminal, which will be described separately below.

[0047] Please refer to Figure 1 , Figure 1 which is a schematic flowchart of an embodiment of the method for automatically adjusting the brightness of a ship terminal provided by the present invention. In a specific embodiment of the present invention, a method for automatically adjusting the brightness of a ship terminal is disclosed, including:

[0048] S101. Preprocess the collected indoor and outdoor ambient light information of the cab to obtain the indoor ambient light intensity and the outdoor ambient light intensity;

[0049] S102. Calculate the target brightness of the ship terminal according to the indoor ambient light intensity and the outdoor ambient light intensity;

[0050] S103. Generate a brightness control signal based on the target brightness of the ship terminal and adjust the brightness of the ship terminal to the target brightness of the ship terminal.

[0051] In the above embodiment, first, high-precision optical sensors are respectively arranged at key positions inside and outside the cab to capture the light changes inside and outside the cab in real time. Then, the collected original optical signals are filtered to remove noise interference and ensure the accuracy of the data. Then, through algorithm conversion, the processed optical signals are converted into specific indoor ambient light intensity and outdoor ambient light intensity values for subsequent calculations.

[0052] Introduce a difference-sensitive factor, combine the indoor and outdoor ambient light intensities through the difference-sensitive factor, and calculate the target brightness value of the ship terminal. The target brightness value is a brightness level that can not only ensure display clarity but also avoid crew eye fatigue. It is also possible to establish a user habit model based on historical brightness adjustment records (storage period ≥ 7 days) through a clustering algorithm (such as K-means), allowing manually set preference weights to override the system default parameters. When a sudden increase in ambient light intensity is detected (such as strong sunlight), start the emergency brightness reduction mode, and the target brightness drops to the safety threshold within 200 ms.

[0053] Utilize a microprocessor or a dedicated brightness control system to receive and parse the calculated target brightness value. According to the target brightness value, automatically adjust the brightness settings of the ship terminal (such as the display screen, console backlight, etc.), and achieve smooth and precise brightness adjustment through PWM (Pulse Width Modulation). Real-time monitor the actual brightness after adjustment, compare it with the target brightness, and form a closed-loop feedback system to ensure that the brightness is always maintained within the set optimal range and can respond quickly even when the environmental conditions change rapidly.

[0054] Compared with the prior art, a method for automatically adjusting the brightness of a ship terminal provided in this embodiment realizes the efficiency and safety of brightness adjustment through a closed-loop architecture of environmental perception-intelligent decision-making-precise control. It can automatically offset the influence of strong light direct irradiation (such as deck sunlight) or low-light environment (such as night navigation) on the ship terminal, ensuring that the brightness is always within the comfortable range of the human eye, regardless of whether the ship is sailing in sunny, cloudy, rainy or foggy weather, or in indoor / outdoor switching scenarios. By calculating the target brightness of the ship terminal by real-time collecting the indoor and outdoor ambient light intensities and generating a brightness control signal to adjust the brightness of the ship terminal to the target brightness of the ship terminal, the brightness adjustment process is relatively smooth, without dazzling flicker, making the brightness adjustment more in line with the comfort of the human eye, avoiding frequent changes, realizing a fully automatic adjustment process without the need for crew to manually adjust the brightness, reducing the display failure rate caused by human negligence, and maintaining brightness stability.

[0055] Please refer to Figure 2 , Figure 2 For the Figure 1 flow schematic diagram of an embodiment of step S102 provided by the present invention. In some embodiments of the present invention, calculating the target brightness of the ship terminal according to the indoor ambient light intensity and the outdoor ambient light intensity further includes:

[0056] S201. Calculate the difference-sensitive factor according to the indoor ambient light intensity and the outdoor ambient light intensity;

[0057] S202. Calculate the initial brightness of the ship terminal according to the difference-sensitive factor, the indoor ambient light intensity and the outdoor ambient light intensity;

[0058] S203. Optimize the initial brightness of the ship terminal to obtain the target brightness of the ship terminal.

[0059] In the above embodiment, the difference sensitivity factor is a quantitative index reflecting the influence degree of the indoor-outdoor light difference on the crew's vision. First, calculate the absolute value of the difference between the indoor ambient light intensity and the outdoor ambient light intensity (i.e., the indoor-outdoor brightness difference) to better simulate the sensitivity of the human eye to light changes. Then, according to a preset threshold value (10 cd / m 2 ), convert the indoor-outdoor brightness difference into a difference sensitivity factor. The larger this factor is, the greater the influence of the indoor-outdoor light difference on the crew's vision, and a more detailed brightness adjustment strategy is required to reduce the visual abruptness. The specific calculation formula of the difference sensitivity factor k is as follows:

[0060]

[0061] where |ΔL| represents the absolute value of the difference between the indoor ambient light intensity and the outdoor ambient light intensity.

[0062] Use the difference sensitivity factor to weight the indoor and outdoor ambient light intensities to obtain a preliminary brightness setting value. The specific calculation formula is as follows:

[0063]

[0064] where L in and L out represent the indoor ambient light intensity and the outdoor ambient light intensity respectively. The parameter α is a constant to prevent division by zero, which is used to prevent calculation errors caused by the denominator being zero. As a preferred embodiment, the parameter α is set to 0.1.

[0065] After the initial brightness is set, the initial brightness can be fine-tuned according to historical data and crew feedback to achieve the best visual comfort and work efficiency. At the same time, considering the navigation state of the ship (such as stationary, sailing, entering or leaving the port, etc.), dynamically adjust the brightness strategy to adapt to different navigation environments, and the brightness needs to be adjusted smoothly. Finally, the optimized brightness value is determined as the target brightness of the ship terminal, which not only meets the visual needs of the crew but also takes into account safety and work efficiency.

[0066] In some embodiments of the present invention, optimizing the initial brightness of the ship terminal to obtain the target brightness of the ship terminal further includes:

[0067] Determine a smoothing coefficient according to the current brightness of the ship terminal, the initial brightness of the ship terminal and a preset difference threshold;

[0068] Perform a smoothing transition process according to the current brightness of the ship terminal, the initial brightness of the ship terminal and the smoothing coefficient to obtain the target brightness of the ship terminal.

[0069] In the above embodiments, the smoothing coefficient β is a value between 0 and 1, which is used to control the smoothness of brightness adjustment. The greater the difference, the smaller the smoothing coefficient may be, which means that the brightness adjustment will be more rapid to adapt to environmental changes; the smaller the difference, the larger the smoothing coefficient may be, which means that the brightness adjustment will be more gradual to reduce the sudden impact on the crew's vision. The specific method for determining the smoothing coefficient is as follows:

[0070]

[0071] where, △L th is the preset difference threshold, and L current is the current brightness of the ship terminal.

[0072] Using the smoothing coefficient to "soften" the brightness change makes the process of the brightness transitioning from the current value to the initial brightness (i.e., the calculated ideal value) smoother. The difference between the current brightness and the initial brightness is distributed according to the smoothing coefficient, so as to gradually adjust the brightness value to obtain the target brightness of the ship terminal. This brightness value takes into account both the change in ambient light and the smoothness of brightness adjustment and the comfort of the crew's vision. Specifically as follows:

[0073] L target = β·L current +(1 - β)·L initial .

[0074] In some embodiments of the present invention, calculating the target brightness of the ship terminal according to the indoor ambient light intensity and the outdoor ambient light intensity further includes:

[0075] If the indoor ambient light intensity exceeds the preset ambient light intensity range or the outdoor ambient light intensity exceeds the preset ambient light intensity range, the target brightness of the ship terminal is set to the preset brightness.

[0076] In the above embodiments, during actual navigation, the indoor and outdoor ambient light intensities may encounter extreme situations, such as the indoor lights being too bright and causing glare, or the outdoor sunlight shining directly and causing strong reflections. During the brightness calculation process, it is necessary to set the preset ranges of the indoor and outdoor ambient light intensities. These ranges are set based on research on crew visual comfort, analysis of terminal display characteristics, and consideration of the navigation environment, aiming to ensure that the brightness adjustment algorithm can provide appropriate brightness settings in most cases.

[0077] When it is detected that the indoor ambient light intensity exceeds the preset range, it indicates that the indoor light is too strong or too weak, which may cause discomfort to the crew's eyes or affect work efficiency. At this time, the brightness adjustment system will set the target brightness of the ship terminal to a preset brightness value L default, this value is usually a medium and comfortable brightness level, which can reduce the negative impact on the crew's vision.

[0078] It should be noted that the setting of the preset brightness should be a flexible and adjustable parameter, which can be adjusted according to different navigation environments, crew needs and terminal characteristics. At the same time, the system should also have an automatic recovery function. When the ambient light intensity returns to the normal range, it can automatically recalculate and apply the new target brightness value.

[0079] In some embodiments of the present invention, generating a brightness control signal based on the target brightness of the ship terminal to adjust the brightness of the ship terminal to the target brightness of the ship terminal further includes:

[0080] Mapping the target brightness of the ship terminal to the brightness control signal range of the ship terminal to obtain a brightness control signal;

[0081] Determining to adjust the brightness of the ship terminal to the target brightness of the ship terminal according to the brightness parameter of the ship terminal and the brightness control signal.

[0082] In the above embodiments, the brightness control signal range of the ship terminal is usually defined by the hardware characteristics and control interface of the ship terminal. It defines the minimum and maximum values that the brightness control signal can take, as well as the brightness levels corresponding to these values. Mapping the calculated target brightness of the ship terminal to this range to obtain a specific brightness control signal value. This value is within the brightness control signal range of the ship terminal and corresponds to the target brightness value, and can be used to control the brightness adjustment mechanism of the ship terminal to achieve the setting of the target brightness.

[0083] During the adjustment process, the brightness parameters of the ship terminal need to be considered. These parameters may include the step size, response time and stability of brightness adjustment, etc. According to the brightness control signal and brightness parameters, the brightness adjustment mechanism will gradually adjust the brightness level of the ship terminal until the target brightness value is reached. During the adjustment process, the brightness change can also be monitored in real time and fine-tuned as needed, which can further improve the accuracy and stability of brightness adjustment and ensure that the brightness of the ship terminal always remains near the target level.

[0084] In some embodiments of the present invention, mapping the target brightness of the ship terminal to the brightness control signal range of the ship terminal to obtain a brightness control signal further includes:

[0085] If the target brightness of the ship terminal exceeds the preset brightness maximum value, set the brightness control signal to the maximum value of the brightness control signal range;

[0086] If the target brightness of the ship terminal is less than the preset brightness minimum value, set the brightness control signal to the minimum value of the brightness control signal range;

[0087] If the target brightness of the ship terminal is between the preset maximum brightness and the preset minimum brightness, the brightness control signal is calculated by mapping according to the brightness control signal range.

[0088] In the above embodiment, according to the target brightness L of the ship terminal target and the preset brightness range [L min , L max , the brightness value is converted into a brightness control signal C compatible with the hardware signal , when Ltarget is within the normal range (that is, between the preset maximum brightness and the preset minimum brightness), a piecewise linear function is used for mapping:

[0089]

[0090] where C min , C max are the minimum and maximum values of the brightness control signal range of the ship terminal.

[0091] To prevent out-of-bounds problems caused by floating-point operation errors or sensor abnormalities, hard constraints need to be imposed on the mapping results:

[0092]

[0093] When the target brightness of the ship terminal exceeds the preset maximum brightness, if this value is directly applied for brightness adjustment, it may cause the brightness of the ship terminal to be too high, thus causing discomfort or damage to the crew's eyes. Therefore, in this case, the brightness adjustment system will set the brightness control signal to the maximum value of the brightness control signal range. This maximum value usually corresponds to the maximum brightness level that the ship terminal can safely display to ensure that it will not cause visual harm to the crew.

[0094] Similar to the case where the preset maximum brightness is exceeded, when the target brightness of the ship terminal is lower than the preset minimum brightness, if this value is directly applied for brightness adjustment, it may cause the brightness of the ship terminal to be too low, thus affecting the readability of the displayed content and the work efficiency of the crew. In this case, the brightness adjustment system will set the brightness control signal to the minimum value of the brightness control signal range. This minimum value usually corresponds to the minimum brightness level at which the ship terminal can clearly display the content to ensure the readability of the displayed content.

[0095] When the target brightness of the ship terminal is between the preset maximum brightness and the minimum brightness, it indicates that the target brightness is within the safe brightness adjustment range. At this time, the brightness adjustment system will perform a mapping calculation based on the brightness control signal range to obtain a specific brightness control signal value. The mapping calculation may involve methods such as linear transformation, non-linear transformation, or look-up tables, depending on the brightness control characteristics of the ship terminal and the required adjustment accuracy. The result of the mapping calculation is a specific brightness control signal value that is within the brightness control signal range and corresponds to the target brightness value.

[0096] Please refer to Figure 3 , Figure 3 which is a schematic flowchart of a process of an embodiment for adjusting the brightness of a ship terminal provided by the present invention. In some embodiments of the present invention, adjusting the brightness of the ship terminal to the target brightness of the ship terminal according to the ship terminal brightness parameter and the brightness control signal further includes:

[0097] S301. Calculate the brightness adjustment duty cycle according to the brightness control signal and the brightness control signal range;

[0098] S302. Adjust the brightness of the ship terminal to the target brightness of the ship terminal based on the brightness adjustment duty cycle;

[0099] S303. Calculate the error according to the real-time brightness of the ship terminal and the target brightness of the ship terminal, and dynamically correct the brightness of the ship terminal based on the error.

[0100] In the above embodiment, converting the brightness control signal into a brightness adjustment duty cycle represents a parameter that indicates the time ratio of the on and off of a brightness adjustment mechanism (such as an LED driver, a dimming circuit, etc.) within a period of time. By linear interpolation or other appropriate mathematical methods, the brightness control signal is mapped onto the duty cycle range to obtain a specific duty cycle value, and the duty cycle value will directly control the output of the brightness adjustment mechanism, thereby affecting the brightness level of the ship terminal.

[0101] Applying the brightness adjustment duty cycle to the brightness adjustment mechanism of the ship terminal, adjusting its output according to the value of the duty cycle, thereby changing the brightness level of the ship terminal. The brightness adjustment mechanism can be an electronic dimming circuit, a PWM (pulse width modulation) controller, or other types of brightness adjustment devices. Regardless of which mechanism is adopted, its goal is to accurately adjust the brightness level according to the duty cycle to reach the target brightness. During this process, it is necessary to monitor the brightness change in real time and perform fine adjustment as needed to further improve the accuracy and stability of the brightness adjustment.

[0102] To ensure the accuracy of brightness adjustment, the system needs to continuously monitor the brightness level of the ship terminal and compare it with the target brightness. The result of this comparison is an error value, which represents the difference between the current brightness and the target brightness. If the error value exceeds the preset tolerance range, the brightness will be dynamically corrected. The correction process involves adjusting the brightness adjustment duty cycle, changing the brightness adjustment strategy, or taking other measures to reduce the error. The goal of dynamic correction is to make the brightness level of the ship terminal as close as possible to the target brightness value while maintaining the stability and smoothness of the adjustment process. Through continuous monitoring and correction, the system can gradually reduce the error until the required brightness accuracy is achieved.

[0103] To better implement the automatic brightness adjustment method for ship terminals in the embodiments of the present invention, based on the automatic brightness adjustment method for ship terminals, correspondingly, please refer to Figure 4 , Figure 4 which is a schematic structural diagram of an embodiment of the automatic brightness adjustment device for ship terminals provided by the present invention.
