Description

TECHNICAL FIELD

[0001] The embodiment of the application relates to the technical field of advertisement display, in particular to a vehicle-mounted automatic expansion shelter. BACKGROUND

[0002] With the continuous expansion of human activities, the living environment of wild animals has been seriously threatened. In some remote areas or harsh conditions, the behavior of privately hunting wild animals still exists, which poses a great challenge to biodiversity and ecological balance.

[0003] In order to strengthen the protection of wild animals, the traditional publicity methods such as setting fixed billboards have played a certain warning role, but due to the fixed position, easy damage by natural conditions and inconvenient content updating, it is difficult to achieve long-term effective publicity effect. SUMMARY

[0004] The embodiment of the application provides a vehicle-mounted automatic expansion shelter, so as to at least solve the problem that the billboard in the related art is difficult to achieve long-term effective publicity effect.

[0005] According to an embodiment of the application, a vehicle-mounted automatic expansion shelter is provided, comprising:

[0006] The shelter shell is detachably connected to the tail of the vehicle head and is provided with a moving wheel;

[0007] The display screen is detachably connected to the outer facade of the shelter shell;

[0008] The control system is used for adjusting the target brightness based on the environmental light intensity adjustment parameter, time and position of the shelter shell, and adjusting the brightness of the display screen based on the target brightness.

[0009] By adopting the above technical solutions, since the shelter shell and the display screen can be detachably connected, it means that the shelter shell can be conveniently installed and unloaded, improving the flexibility and convenience of use. Moreover, the shelter shell is provided with moving wheels, so that the shelter can be moved to different positions when needed, increasing the flexibility of use. The control system can adjust the parameters based on the ambient light intensity, which means that the shelter can automatically adjust the brightness of the display screen according to the lighting conditions of the surrounding environment to adapt to different use scenarios. The control system will obtain a target brightness and adjust the brightness of the display screen based on the target brightness. Such a design can ensure that the display screen can provide clear and comfortable visual experience under different lighting conditions. The entire system is automated and can automatically adjust the brightness of the display screen according to environmental changes without human intervention, reducing the operation complexity and improving the use efficiency. By automatically adjusting the brightness of the display screen to adapt to the ambient light, unnecessary energy consumption can be avoided, achieving energy-saving effect. In the case of unsatisfactory lighting conditions, automatically adjusting the brightness of the display screen can improve the visibility of the display screen, thereby reducing the safety hazards caused by the display screen being too bright or too dark. Therefore, the user does not need to manually adjust the brightness of the display screen, and the control system will automatically optimize according to the ambient light conditions to provide a more comfortable visual experience. Further, the automatic adjustment of the brightness of the display screen also reduces the impact of light pollution on wild animals.

[0010] Optionally, the control system comprises:

[0011] The acquisition module is configured to acquire the time and the position of the shelter shell.

[0012] The algorithm module is configured to obtain the target brightness based on the following algorithm:

[0013] L screen =min(L max ,max(L min ,L ′ screen *T*S*A*C))

[0014] wherein L screen is the target brightness of the display screen, L max is the maximum threshold value of the brightness of the display screen, L min is the minimum threshold value of the brightness of the display screen, L ′ screen is the ambient light intensity adjustment parameter, T is the time factor, S is the position factor, A is the environmental adaptability coefficient, and C is the color correction factor.

[0015] By adopting the above technical solution, the brightness of the display screen can be adjusted by a specific algorithm to achieve the purpose of providing optimal visual effect under different environmental lighting conditions. This algorithm considers multiple factors, including environmental lighting intensity adjustment parameter (L ′ screen ), time factor (T), location factor (S), environmental adaptability coefficient (A), and color correction factor (C). These factors work together to calculate the target brightness (L screen ) of the display screen and ensure it is between the maximum brightness threshold (L max ) and the minimum brightness threshold (L min ). Specifically, the control system can automatically adjust the brightness of the display screen according to changes in environmental lighting, ensuring a comfortable visual experience under different lighting conditions. The time factor is related to different times of the day, such as automatically reducing brightness at night to reduce eye irritation. The location factor is related to the location of the shelter shell, such as when the shelter is moved to different locations or directions, the control system adjusts the brightness of the display screen according to the environmental lighting conditions of the new location. Through the environmental adaptability coefficient (A), the control system can optimize the adjustment according to the characteristics of the current environment (such as weather, season, etc.). The color correction factor (C) ensures that the color output of the display screen remains accurate while adjusting the brightness, and does not produce color difference due to changes in brightness. By precisely controlling the brightness of the display screen, the control system can avoid unnecessary energy consumption, thereby achieving energy saving. Users do not need to manually adjust the brightness of the display screen, and the control system will automatically optimize to provide a more comfortable visual experience.

[0016] Optionally, the environmental lighting intensity adjustment parameter is based on the environmental lighting intensity.

[0017] Optionally, the algorithm for calculating the environmental lighting intensity adjustment parameter is:

[0018] L ′ screen = K ;

[0019] where L ′ screen is the environmental lighting intensity adjustment parameter, K is the adjustment coefficient, L env is the environmental lighting intensity, and α, is the nonlinear adjustment parameter.

[0020] By adopting the above technical solution, the environmental lighting intensity adjustment parameter calculation algorithm is a nonlinear adjustment process that calculates the appropriate display screen brightness adjustment parameter L ′ screen through a specific mathematical formula. This algorithm takes into account the environmental lighting intensity L env, a non-linear adjustment parameter a and b. This non-linear adjustment method can more finely control the brightness of the display screen to adapt to different ambient light conditions. Specifically, through the two non-linear adjustment parameters a and b, the algorithm can achieve a non-linear response to changes in ambient light intensity, making the adjustment of the display screen brightness more smooth and natural. K as the adjustment coefficient can control the amplitude of brightness adjustment, making the system's response to environmental changes more flexible. Under different ambient light conditions, by adjusting L ′ screen , the display screen can automatically adapt to provide the best visual effect. By automatically adjusting the brightness of the display screen, the user's trouble of manually adjusting the brightness of the display screen due to changes in ambient light is reduced, and the impact on the user's vision caused by improper brightness is also reduced. Reasonable brightness adjustment helps to reduce unnecessary energy consumption, especially when the ambient light is strong, the display screen brightness can be appropriately reduced to save energy. Therefore, this brightness adjustment method based on a non-linear algorithm can make the display screen of the vehicle-mounted automated expansion shelter automatically adjust to the best state under different ambient light conditions, improve visual comfort, and also has the effects of energy saving and improving user experience.

[0021] Optionally, it further comprises:

[0022] a light sensor for obtaining the ambient light intensity;

[0023] a GPS module for obtaining the coordinate position of the shelter shell;

[0024] a camera for obtaining image data of the environment where the shelter shell is located;

[0025] wherein the control system is further configured to obtain the location factor based on the ambient light intensity, the coordinate position, and the image data.

[0026] Optionally, the control system obtains the location factor based on the following algorithm:

[0027] S = w Lenv *L env +w GPS *GPS + w I *I;

[0028] wherein w Lenv , w GPS , and w I are weight coefficients, GPS is the coordinate position of the shelter shell obtained by the GPS module, and I is the image data of the environment where the shelter shell is located obtained by the camera.

[0029] By adopting the above technical solutions, the environment state in which the shelter shell is located can be comprehensively perceived through the integrated light sensor, GPS module and camera. These sensors respectively acquire environmental illumination intensity, coordinate position of the shelter shell and environmental image data, providing rich input information for the control system. Specifically, the light sensor is used to monitor the environmental illumination intensity in real time, so that the control system can adjust the display screen brightness according to the environmental brightness change, to ensure the visibility of the display screen under different illumination conditions. The GPS module is used to provide accurate position information of the shelter shell, which can be used for various applications, such as automatically adjusting the working mode of the shelter or the display content of the display screen at a specific geographic location. The camera is used to capture image data of the environment in which the shelter shell is located, which can be used to analyze environmental features, such as identifying surrounding objects, monitoring traffic conditions, etc., and then the control system can make corresponding adjustments according to these information. The control system uses these sensor data to calculate a position factor (S) through a specific algorithm, which is a weight coefficient that comprehensively considers environmental illumination, geographic position and image data. Such a design enables the shelter shell to intelligently adapt to the environment it is in, improving its functionality and user experience in different scenarios. For example, if the shelter shell is located in an area with strong light or shading, the control system will adjust the display screen brightness according to the data of the light sensor; if the shelter shell moves to a new location, the position information of the GPS module will help the system understand the current geographic location and adjust the working parameters accordingly; the image data provided by the camera can be used to analyze the surrounding environment, such as identifying obstacles or crowds or animal groups, so as to adjust the operation of the shelter shell or the display content of the display screen when needed. Therefore, the design of such a control system enables the vehicle-mounted automated expansion shelter to work more intelligently and adaptively, improving its practicality and efficiency in various environments.

[0030] Optionally, the control system is further configured to compare the position factor with a preset threshold to determine a sunshade condition.

[0031] Optionally, the comparison of the position factor with the preset threshold to determine the sunshade condition comprises:

[0032] In a case where the position factor is less than or equal to a first threshold, it is determined that the shelter shell is in a completely sunshaded environment;

[0033] In a case where the position factor is between the first threshold and a second threshold, it is determined that the shelter shell is in a partially sunshaded environment;

[0034] In a case where the position factor is greater than or equal to the second threshold, it is determined that the shelter shell is in a non-sunshaded environment;

[0035] The preset threshold value includes the first threshold value and the second threshold value, and the first threshold value is less than the second threshold value.

[0036] By adopting the above technical solution, the environment state in which the shelter shell is located can be comprehensively perceived through the integrated light sensor, GPS module and camera. These sensors respectively acquire environmental illumination intensity, coordinate position of the shelter shell and environmental image data, to provide rich input information for the control system. The control system comprehensively calculates the position factor (S) from these data, and intelligently determines the sun-shading condition of the shelter shell through comparison with the preset threshold value. Specifically, the control system can intelligently determine whether the shelter shell is in a sun-shading environment and the degree of sun-shading, and further determine the illumination intensity, by comparing the calculated position factor with the preset threshold value.

[0037] Optionally, the acquisition module is further configured to acquire a current brightness of the display screen.

[0038] The algorithm module is further configured to determine a direction and a step length of brightness adjustment based on the current brightness and the target brightness, and to adjust the current brightness to the target brightness based on the direction and the step length.

[0039] Optionally, the control system acquires the current brightness based on a software driver of the display screen or a light sensor built in the display screen.

[0040] By adopting the above technical solution, the direction and the step length of brightness adjustment can be accurately calculated, and the control system can gradually adjust the brightness of the display screen to the target brightness instead of making a large and abrupt adjustment, so that the discomfort caused by rapid brightness change to the user's eyes can be avoided. The smooth transition of brightness can provide a more comfortable visual experience, especially when the environmental illumination condition changes, the user will not feel obvious brightness change, and visual fatigue is reduced. The control system can adjust the brightness of the display screen according to the environmental illumination and user demand, to avoid unnecessary energy consumption. For example, the brightness of the display screen can be appropriately reduced when the environmental illumination is strong, and the brightness of the display screen can be appropriately increased when the environmental illumination is weak, to reduce the energy consumption of the backlight. The control system can acquire the current brightness based on the software driver or the light sensor built in the display screen, and this intelligent control method reduces manual intervention and improves the automation degree of the control system. The control system can automatically adjust the brightness of the display screen according to the change of the environmental illumination intensity, so that the display screen can maintain good display effect under different illumination conditions, and the adaptability of the display screen and the convenience of the user are improved. By avoiding long-time work of the display screen at the highest brightness, the wear of the display screen can be effectively reduced, and the service life thereof is prolonged.

[0041] In summary, the embodiments of the present invention, by using vehicle-mounted automated expansion shelter technology, solve the problem in related technologies that fixed billboards are difficult to achieve long-term and effective publicity effects, thereby achieving the effect of improving publicity efforts for wildlife protection in some remote areas or places with harsh conditions. Specifically:

[0042] Enhanced mobility: The mobile wheels and detachable design of the vehicle-mounted shelter enable the publicity shelter to be flexibly carried out in different regions and locations, especially in remote areas or places with harsh conditions. This mobility means that publicity is not restricted by geographical location.

[0046] Automation and remote control: Vehicle-mounted shelters can be operated via remote control, reducing the need for on-site staff and lowering labor costs, while improving response speed and operational convenience, making publicity more efficient.

[0047] Versatility: In addition to being a publicity tool, the vehicle-mounted shelter can also be multifunctionally expanded as needed, such as serving as a temporary observation station, research station or rescue station, increasing its practicality in wildlife protection work.

[0048] Improve publicity efforts: Since the vehicle-mounted cabin can be moved to remote areas or places with harsh conditions, it can directly bring information about wildlife protection to these areas, raising the awareness of conservation among local residents and tourists, thereby improving publicity efforts in these areas.

[0049] In summary, the embodiments of the present invention effectively overcome the limitations of traditional fixed billboards in wildlife protection publicity through the design of a vehicle-mounted automated expansion cabin, improve the flexibility, effectiveness and coverage of publicity, and help strengthen wildlife protection work.

[0053] Hereinafter, embodiments of the present application will be described in detail with reference to the accompanying drawings and in conjunction with embodiments.

[0054] It should be noted that the terms "first", "second", and the like in the specification and claims of the present application and in the above-described drawings are used to distinguish similar objects, and do not necessarily have to be used to describe a specific order or sequence.

[0055] In the present embodiment, a vehicle-mounted automatic expansion shelter is provided, Figure 1 is a structural schematic view of a vehicle-mounted automatic expansion shelter according to an embodiment of the present application, as Figure 1 shown, the vehicle-mounted automatic expansion shelter comprises: a shelter shell 1, a display screen 2, and a control system 3. Among them,

[0056] The shelter shell 1 is detachably connected to the tail of the vehicle head 4 and is provided with moving wheels;

[0057] In an exemplary embodiment, the shelter shell 1 is a box structure, and inside it can place maintenance tools of the display screen 2, spare display screens 2, etc. Alternatively, inside it can place beds, drinking water and other living supplies, so as to facilitate the night duty of the on-duty personnel, or to facilitate the emergency of the outdoor personnel. The shelter shell 1 and the vehicle head 4 are detachably connected through the car hook, when the vehicle head 4 transports the shelter shell 1 to the target location, then the vehicle head 4 and the shelter shell 1 can be separated, the shelter shell 1 is left in the target location, to show the propaganda work of protecting wild animals through the display screen 2. When it is needed to move to other positions, for short distance movement, the operator can move the shelter shell 1 by using the moving wheels. For long distance movement, the vehicle head 4 and the shelter shell 1 can be connected by using the car hook, so as to move the shelter shell 1 by using the vehicle head 4 and the moving wheels. Alternatively, in order to improve the convenience of movement, the vehicle head 4 and the shelter shell 1 can be left in the target location.

[0058] The display screen 2 is detachably connected to the outer facade of the shelter shell 1;

[0059] In an exemplary embodiment, the display screen 2 can be an LED display screen, an OLED display screen, etc. Inside it can use micro light-emitting diodes, micron light-emitting diodes, mini light-emitting diodes, sub-millimeter light-emitting diodes, small-pitch light-emitting diodes, etc. as light-emitting units. The display screen 2 can be installed at the positions on both sides of the shelter shell 1 (as shown in Figure 1 The display screen 2 can be installed at the tail of the shelter shell 1, or, in order to improve the display effect, the display screen 2 can be installed at the top of the shelter shell 1. The installation position, installation angle, etc. of the display screen 2 and the shelter shell 1 can be relatively fixed, or a gas cylinder, a hinge, etc. can be installed between the display screen 2 and the shelter shell 1 to facilitate changing the position, angle of orientation, etc. of the display screen 2.

[0060] The control system 3 is used to obtain the target brightness based on the ambient light intensity adjustment parameter, time, and position of the shelter shell 1, and adjust the brightness of the display screen 2 based on the target brightness.

[0061] In an exemplary embodiment, in combination with the use scenario of the vehicle-mounted automatic expansion shelter, for example, in the case where the shelter shell 1 needs to be frequently moved, the vehicle head 4 and the shelter shell 1 can both be left at the target location, and then the control system 3 can be integrated into the central control system of the vehicle head 4. In the case where the shelter shell 1 needs to be infrequently moved, the shelter shell 1 can be left at the target location only, and the control system 3 can also be installed inside the shelter shell 1.

[0062] In order to realize the function of adjusting the brightness of the display screen 2 based on the ambient light intensity, the control system 3 needs to rely on a series of sensors, actuators, and control algorithms. The following are the components that may be needed to realize this function and the way information is transmitted between them:

[0063] Ambient light sensor: used to detect the light intensity and other parameters of the external environment, so as to obtain the ambient light intensity adjustment parameter. These sensors can be installed outside the shelter shell 1 to monitor the changes of ambient light in real time.

[0064] Display screen 2 brightness sensor: used to detect the current brightness of the display screen 2 for comparison with the target brightness.

[0065] Control system 3: can include a microprocessor or microcontroller that runs control algorithms to process sensor data and make decisions. For example, the control system 3 can use a PID (Proportional-Integral-Derivative) control algorithm to adjust the brightness of the display screen 2 to adapt to changes in ambient light.

[0066] Actuator: in this case, the actuator can be the backlight control circuit of the display screen 2, which receives signals from the control system 3 and adjusts the brightness accordingly.

[0067] Interface: Communication between sensors, control system 3, and actuators through electrical or wireless interfaces. These interfaces can be analog or digital, depending on the design of the system.

[0068] Power management unit: Provides stable power supply for sensors, control system 3, and actuators.

[0069] The information transmission process is as follows:

[0070] The ambient light sensor detects changes in light intensity and sends data to the control system 3.

[0071] The control system 3 calculates the ambient light intensity adjustment parameters based on the received ambient light data, and combines information such as time and the location of the shelter shell 1 to calculate the target brightness.

[0072] The control system 3 sends the target brightness to the backlight control circuit of the display screen 2.

[0073] The display screen 2 brightness sensor detects the current brightness and compares it with the target brightness.

[0074] If the current brightness is inconsistent with the target brightness, the control system 3 adjusts the backlight control circuit until the display screen 2 brightness reaches the target brightness.

[0075] In some embodiments, the control system 3 can also include other sensors such as an inclination sensor (for detecting the horizontal state of the shelter) and a position sensor (for determining the geographical position of the shelter, so as to adjust the brightness of the display screen 2 according to the geographical position and time). The data of these sensors can be used by the control system 3 to further optimize the brightness adjustment of the display screen 2.

[0076] By adopting the above technical solution, the problem of fixed billboards in related technologies that are difficult to achieve long-term effective publicity effect is solved by using vehicle-mounted automatic expansion shelter technology, thereby achieving the effect of improving the publicity strength of protecting wild animals in some remote areas or harsh conditions. Specifically:

[0077] Mobility enhancement: The mobile wheels and detachable design of the vehicle-mounted shelter allow the publicity shelter to be flexible in different areas and different locations, especially in remote areas or harsh conditions, and this mobility makes the publicity not limited by geographical location.

[0078] Environmental adaptability improvement: The design of the vehicle-mounted shelter takes into account the adaptability to the environment, and can be used in various climate conditions, thereby ensuring the continuity and effectiveness of the publicity, even in harsh natural environments.

[0079] Convenience of content update: The display screen 2 and control system 3 provided in the vehicle-mounted shelter allow quick updating of promotional content. Through automated technical means, promotional information can be quickly adjusted remotely or on-site, improving the timeliness and flexibility of the promotion.

[0080] Intelligent brightness adjustment: The control system 3 of the vehicle-mounted shelter can automatically adjust the brightness of the display screen 2 based on environmental light intensity, time, shelter location, and other factors. This intelligent adjustment ensures good visual effects at different times and under different lighting conditions, improving the visibility and appeal of promotional information.

[0081] Automation and remote control: The vehicle-mounted shelter can be operated through remote control, reducing the need for on-site staff, reducing labor costs, and improving response speed and operational convenience, making the promotion more efficient.

[0082] Multifunctionality: In addition to serving as a promotional tool, the vehicle-mounted shelter can be multifunctionally expanded as needed, such as a temporary observation station, research station, or rescue station, increasing its practicality in wildlife protection work.

[0083] Improved promotional intensity: Since the vehicle-mounted shelter can be moved to remote or harsh conditions, it can directly bring wildlife protection information to these areas, improving the protection awareness of local residents and tourists, thereby improving the promotional intensity in these areas.

[0084] In summary, the embodiment of the present application overcomes the limitations of traditional fixed billboards in wildlife protection promotion by designing a vehicle-mounted automated expansion shelter, improving the flexibility, effectiveness, and coverage of the promotion, and helping to strengthen wildlife protection work.

[0085] Figure 2 is a structural schematic diagram of the control system according to the embodiment of the present application. In one embodiment, as shown in Figure 2 the control system 3 includes:

[0086] The acquisition module 31 is used to acquire the time and the position of the shelter shell 1.

[0087] In an exemplary embodiment, the acquisition module 31 of the control system 3 can obtain the position information of the shelter from the GPS module built-in the display screen 2, and obtain the sunrise and sunset time through the API or website of the weather station. Alternatively, based on the relatively mature software and application programs, the position information and time information of the shelter can be obtained.

[0088] The algorithm module 32 is used to obtain the target brightness based on the following algorithm:

[0089] L screen =min(Lmax max(L min , L ′ screen T*S*A*C)

[0090] wherein L screen is the target luminance of the display screen 2, L max is the maximum threshold value of the luminance of the display screen 2, L min is the minimum threshold value of the luminance of the display screen 2, L ′ screen is the ambient light intensity adjustment parameter, T is the time factor, S is the location factor, A is the environmental adaptability coefficient, and C is the color correction factor.

[0091] In an exemplary embodiment, T is the time factor, calculated based on sunrise and sunset times, used to simulate the light changes at different times of the day. S is the location factor, obtained through real-time analysis using GPS and map data combined with image recognition technology, used to distinguish between direct sunlight and shadows.

[0092] A is the environmental adaptability coefficient, used to consider the impact of different environments on the luminance of the display screen 2. It is a coefficient used to adjust the luminance of the display screen 2 to adapt to different environmental conditions. It takes into account environmental factors such as temperature, humidity, atmospheric pressure, etc. on the performance of the display screen 2. Under different environmental conditions, the luminance of the display screen 2 may be affected by changes in physical properties. For example, in high-altitude areas, the thin air may affect the brightness perception of the display screen 2; in high-temperature environments, the display screen 2 may become brighter. The environmental adaptability coefficient is used to adjust the luminance according to these environmental changes to maintain the readability of the display screen 2. For example, if the shelter shell 1 is located in a high-altitude area, the value of the environmental adaptability coefficient can be increased to compensate for the decrease in brightness perception due to the thin air.

[0093] C is the color correction factor, used to consider the impact of ambient light on the color performance of the display screen 2. It is a coefficient used to adjust the color of the display screen 2 to match the color perception under different lighting conditions. It takes into account the impact of ambient light on the color accuracy of the display screen 2. Under different lighting conditions, the human eye's perception of color changes. For example, in daylight, colors may appear more natural, while under indoor lighting, the same colors may appear different. The color correction factor is used to adjust the color of the display screen 2 according to the ambient light to maintain the accuracy and consistency of the color. For example, if the shelter shell 1 is used at dusk, when the natural light is warm-toned, the color correction factor can be used to adjust the color temperature of the display screen 2 so that it can still accurately display colors under warm-toned light.

[0094] In summary, the algorithm module 32 calculates the product of the ambient light intensity adjustment parameter, the time factor, the location factor, the environmental adaptability coefficient, and the color correction factor, obtains a product value, compares the product value with the minimum threshold of the brightness of the display screen 2, selects the larger one of the two, compares the larger one with the maximum threshold of the brightness of the display screen 2, determines the smaller one of the two, and sets the smaller one as the target brightness of the display screen 2.

[0095] In an embodiment, the ambient light intensity adjustment parameter is obtained based on the ambient light intensity.

[0096] In an embodiment, the algorithm for calculating the ambient light intensity adjustment parameter is:

[0097] L ′ screen =K* ;

[0098] wherein, L ′ screen is the ambient light intensity adjustment parameter, K is an adjustment coefficient, L env is the ambient light intensity, a is a non-linear adjustment parameter.

[0099] In an exemplary embodiment, K is an adjustment coefficient, which can be a dynamic value based on the historical data of the ambient light and the performance optimization of the display screen 2, and is used to convert the ambient light into the brightness of the display screen 2. L env is the ambient light intensity, which is usually in lux and represents the brightness of the ambient light in which the display screen 2 is located. a is a non-linear adjustment parameter, which is used to adjust the degree of non-linear response in the formula. This parameter can help to adjust the adjustment speed of the brightness of the display screen 2 under different ambient light intensities. β is a non-linear index, which determines the degree of non-linearity of the influence of the ambient light intensity on the brightness of the display screen 2. When the value of β is large, it indicates that the brightness adjustment is more sensitive to the change of the ambient light.

[0100] Specifically, with respect to the denominator L env , the numerator is adjusted by adding a constant a, so that the adjustment range of the brightness can be reduced when the ambient light intensity is low, and the display screen 2 is prevented from being too bright in a dark environment. The entire fraction indicates that the value of this fraction will increase with the increase of L env , but since the denominator contains a, it limits the growth rate of the fraction, thereby achieving non-linear brightness adjustment.

[0101] Exponent β: by taking the fraction to the power of β, the non-linear characteristics of the brightness response are further adjusted. If β is greater than 1, the non-linear effect will be enhanced; if β is less than 1, the non-linear effect will be weakened.

[0102] Finally, the above calculation result is multiplied by the adjustment coefficient K to obtain the final ambient light intensity adjustment parameter L ′ screen .

[0103] In this way, the brightness of the display screen 2 can be more finely and intelligently adjusted according to the ambient light intensity to provide a more comfortable visual experience and save energy.

[0104] In an embodiment, the vehicle-mounted automated expansion shelter further comprises:

[0105] a light sensor for acquiring the ambient light intensity;

[0106] a GPS module for acquiring the coordinate position of the shelter shell 1;

[0107] a camera for acquiring image data of the environment in which the shelter shell 1 is located;

[0108] The control system 3 is further configured to obtain a position factor based on the ambient light intensity, the coordinate position, and the image data.

[0109] In an embodiment, the control system 3 obtains the position factor based on the following algorithm:

[0110] S = w Lenv *L env +w GPS *GPS + w I *I;

[0111] where w Lenv , w GPS , and w I are weight coefficients, GPS is the coordinate position of the shelter shell 1 acquired by the GPS module, and I is the image data of the environment in which the shelter shell 1 is located acquired by the camera.

[0112] In an exemplary embodiment, w Lenv , w GPS , and w I are weight coefficients that can be optimized through experiments or machine learning algorithms. The control system 3 filters and normalizes the ambient light intensity to obtain the ambient light intensity L env . The GPS data is geocoded to obtain the position information of the shelter shell 1 relative to the surrounding environment to obtain the coordinate position GPS. The image data captured by the camera is feature extracted, such as texture, color, shape, etc., to obtain the image data I. Then, the position factor S is calculated based on the above algorithm on the processed L env , GPS, and I.

[0113] In an embodiment, the control system 3 is further configured to compare the position factor with a preset threshold to determine the sunshade condition.

[0118] wherein the preset threshold comprises the first threshold value and the second threshold value, and the first threshold value is less than the second threshold value.

[0120] In an embodiment, the obtaining module 31 is further configured to obtain a current brightness of the display screen 2.

[0121] The algorithm module 32 is further configured to determine a direction and a step of brightness adjustment based on the current brightness and the target brightness, and to adjust the current brightness to the target brightness based on the direction and the step.

[0122] In an embodiment, the control system 3 obtains the current brightness based on a software driver of the display screen 2 or a light sensor built-in the display screen 2.

[0123] In an exemplary embodiment, adjusting the current brightness of the display screen 2 to the target brightness usually involves hardware control and software algorithm of the display screen 2. This process can be achieved by the following steps:

[0124] Determining the current brightness: First, the current brightness value of the display screen 2 can be obtained by the built-in sensor of the display screen 2 or by querying the current settings of the display screen 2 through software.

[0125] Calculating the brightness difference: Calculate the difference between the target brightness and the current brightness. This can be achieved by simple subtraction: ΔB=B target −B currentWhere B target is the target brightness, B current is the current brightness.

[0126] Determine adjustment direction and step size: Based on the brightness difference ΔB, determine whether to increase or decrease the brightness, and determine the step size for each adjustment. The step size can be set according to system requirements and user experience to ensure that the brightness adjustment is not too abrupt.

[0127] Adjust brightness step by step: Use a loop or timer to adjust the brightness step by step until the target brightness is reached. Each adjustment can be such that B current =B current + ΔB * step. Where step is a positive number less than 1, representing the percentage of each adjustment.

[0128] Use smooth transition: To avoid the discomfort caused by abrupt changes in brightness to the user, a gradual adjustment of brightness can be used, such as using linear interpolation or more complex transition effects.

[0129] Feedback control: During the adjustment process, the actual brightness change can be monitored through a feedback mechanism to ensure the accuracy of the adjustment process. If there is a deviation between the actual brightness and the target brightness, fine-tuning can be performed.

[0130] Complete adjustment: Stop the adjustment process when the current brightness is close enough to the target brightness (within an acceptable error range).
