Technical Field
[0001] The embodiments of the present invention relate to the technical field of advertisement display, and in particular, to a vehicle-mounted automated expansion cabin. Background Art
[0002] With the continuous expansion of human activities, the living environment of wild animals has been seriously threatened. In some remote areas or places with harsh conditions, the behavior of privately hunting wild animals still exists, which poses a huge challenge to biodiversity and ecological balance.
[0003] In order to strengthen the protection of wild animals, traditional publicity methods such as setting up fixed billboards have played a certain warning role, but due to their fixed location, susceptibility to damage by natural conditions, and inconvenience in updating content, it is difficult to achieve long-term and effective publicity effects. Summary of the invention
[0004] The embodiment of the present invention provides a vehicle-mounted automated expansion cabin, which at least solves the problem that billboards in the related art are difficult to achieve long-term and effective publicity effects.
[0005] According to one embodiment of the present invention, there is provided a vehicle-mounted automated expansion cabin, comprising: The cabin shell is detachably connected to the rear of the vehicle head and is provided with moving wheels; A display screen, detachably connected to the outer facade of the cabin shell; The control system is used to adjust parameters, time, and the position of the cabin shell based on the ambient light intensity, obtain the target brightness, and adjust the brightness of the display screen based on the target brightness.
[0006] By adopting the above technical solution, since the cabin shell and the display screen can be detachably connected, this means that the cabin shell can be easily installed and unloaded, which improves the flexibility and convenience of use. Moreover, the cabin shell is provided with moving wheels, so that the cabin can be moved to different positions when needed, which increases the flexibility of use. The control system can adjust parameters based on the ambient light intensity, which means that the cabin can automatically adjust the brightness of the display screen according to the lighting conditions of the surrounding environment to adapt to different usage scenarios. The control system will obtain a target brightness and adjust the brightness of the display screen based on this target brightness. Such a design can ensure that the display screen can provide a clear and comfortable visual experience under different lighting conditions. The entire system is automated, and the brightness of the display screen can be automatically adjusted according to environmental changes without manual intervention, which reduces the complexity of operation and improves the efficiency of use. By automatically adjusting the brightness of the display screen to adapt to the ambient light, unnecessary energy consumption can be avoided and energy saving can be achieved. 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. Furthermore, automatic adjustment of the display brightness also reduces the impact of light pollution on wildlife.
[0007] Optionally, the control system comprises: An acquisition module, used to acquire the time and the location of the shelter shell; The algorithm module is used to obtain the target brightness based on the following algorithm: L screen =min(L max ,max(L min ,L ′ screen *T*S*A*C)) Among them, L screen is the target brightness of the display, L max is the maximum brightness threshold of the display, L min is the minimum threshold of the display brightness, 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.
[0008] By adopting the above technical solution, a specific algorithm can be used to adjust the brightness of the display screen to achieve the purpose of providing the best visual effect under different ambient lighting conditions. This algorithm takes into account multiple factors, including the ambient light 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 of the display (L screen and ensure that it is within the maximum brightness threshold (L max ) and minimum brightness threshold (L min ). Specifically, the control system can automatically adjust the brightness of the display screen according to changes in ambient light to ensure a comfortable visual experience under different lighting conditions. The time factor is related to different times of the day. For example, the brightness may be automatically reduced at night to reduce eye stimulation. The position factor is related to the position of the cabin shell. For example, when the cabin is moved to a different position or direction, the control system will adjust the brightness of the display screen according to the ambient light conditions of the new position. Through the environmental adaptability coefficient (A), the control system can optimize and adjust according to the characteristics of the current environment (such as weather, season, etc.). The color correction factor (C) ensures that while adjusting the brightness, the color output of the display screen remains accurate and does not produce color difference due to changes in brightness. By accurately controlling the brightness of the display screen, the control system can avoid unnecessary energy consumption and thus achieve energy saving. Users do not need to manually adjust the brightness of the display screen, the control system will automatically optimize and provide a more comfortable visual experience.
[0009] Optionally, the ambient light intensity adjustment parameter is obtained based on the ambient light intensity.
[0010] Optionally, the algorithm for calculating the ambient light intensity adjustment parameter is: L ′ screen =K* ; Among them, L ′ screen is the ambient light intensity adjustment parameter, K is the adjustment coefficient, L env is the ambient light intensity, α, is a nonlinear adjustment parameter.
[0011] By adopting the above technical solution, the ambient light intensity adjustment parameter calculation algorithm is a nonlinear adjustment process, which calculates the brightness adjustment parameter L suitable for the display screen through a specific mathematical formula. ′ screen This algorithm takes into account the ambient light intensity L env, adjustment coefficient K and nonlinear adjustment parameters α and β. This nonlinear adjustment method can more finely control the brightness of the display screen to adapt to different ambient lighting conditions. Specifically, through the two nonlinear adjustment parameters α and β, the algorithm can achieve a nonlinear response to changes in ambient light intensity, making the adjustment of the display screen brightness smoother and more natural. K, as an adjustment coefficient, can control the amplitude of brightness adjustment, making the system more flexible to environmental changes. Under different ambient lighting 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 trouble of users manually adjusting the brightness of the display screen due to changes in ambient light is reduced, and the impact of improper brightness on user vision is also reduced. Reasonable brightness adjustment helps to reduce unnecessary energy consumption, especially when the ambient light is strong, the brightness of the display screen can be appropriately reduced to save energy. Therefore, this brightness adjustment method based on nonlinear algorithm can enable the display screen of the vehicle-mounted automation expansion cabin to automatically adjust to the optimal state under different ambient lighting conditions, improve visual comfort, and also have the effect of saving energy and improving user experience.
[0012] Optionally, it also includes: A light sensor, used to obtain the ambient light intensity; A GPS module, used to obtain the coordinate position of the shelter shell; A camera, used to obtain image data of the environment in which the cabin shell is located; Wherein, the control system is also used to obtain the position factor based on the ambient light intensity, the coordinate position, and the image data.
[0013] Optionally, the control system obtains the position factor based on the following algorithm: S=w Lenv *L env +w GPS *GPS+w I *I; Among them, w Lenv 、w GPS 、w I is the weight coefficient, GPS is the coordinate position of the cabin shell obtained by the GPS module, and I is the image data of the environment in which the cabin shell is located obtained by the camera.
[0014] By adopting the above technical solution, the environmental state of the cabin shell can be more comprehensively perceived by integrating light sensors, GPS modules and cameras. These sensors respectively obtain the ambient light intensity, the coordinate position of the cabin shell and the environmental image data, providing rich input information for the control system. Specifically, the ambient light intensity is monitored in real time by using light sensors, so that the control system can adjust the brightness of the display screen according to the change of ambient brightness to ensure the visibility of the display screen under different lighting conditions. The GPS module is used to provide accurate location information of the cabin shell, which can be used for a variety of applications, such as automatically adjusting the working mode of the cabin or the display content of the display screen at a specific geographical location. The camera is used to capture the image data of the environment in which the cabin shell is located. This data can be used to analyze environmental characteristics, such as identifying surrounding objects, monitoring traffic conditions, etc., and then the control system can make corresponding adjustments based on this information. The control system uses these sensor data to calculate the position factor (S) through a specific algorithm. This position factor is a weight coefficient that combines ambient light, geographical location and image data. This design enables the cabin shell to intelligently adapt to its environment and improve its functionality and user experience in different scenarios. For example, if the cabin shell is located in an area with strong light or shade, the control system will adjust the brightness of the display screen according to the data from the light sensor; if the cabin shell moves to a new location, the location information of the GPS module will help the system understand the current geographical 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 groups of people or animals, so as to adjust the operation of the cabin shell or the display content of the display screen when necessary. Therefore, the design of this control system enables the vehicle-mounted automated expansion cabin to work more intelligently and adaptively, improving its practicality and efficiency in various environments.
[0015] Optionally, the control system is further used to compare the position factor with a preset threshold to determine a shading condition.
[0016] Optionally, comparing the position factor with a preset threshold to determine a sunshade condition includes: When the position factor is less than or equal to a first threshold, determining that the shelter shell is in a completely shaded environment; When the position factor is between the first threshold and the second threshold, it is determined that the shelter shell is in a partially shaded environment; When the position factor is greater than or equal to the second threshold, determining that the shelter shell is in an unshaded environment; The preset threshold includes the first threshold and the second threshold, and the first threshold is smaller than the second threshold.
[0017] By adopting the above technical solution, the environmental state of the cabin shell can be more comprehensively perceived through the integrated light sensor, GPS module and camera. These sensors respectively obtain the ambient light intensity, the coordinate position of the cabin shell and the environmental image data, providing rich input information for the control system. The control system combines these data, calculates the position factor (S), and intelligently determines the shading condition of the cabin shell by comparing it with the preset threshold. Specifically, the control system can intelligently determine whether the cabin shell is in a shaded environment and the degree of shading by comparing the calculated position factor with the preset threshold, and then judge the light intensity.
[0018] Optionally, the acquisition module is further used to: acquire the current brightness of the display screen; 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, so as to adjust the current brightness to the target brightness based on the direction and the step length.
[0019] Optionally, the control system acquires the current brightness based on a software driver of the display screen or a light sensor built into the display screen.
[0020] By adopting the above technical solution, the direction and step size 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 large jump adjustments, so as to avoid discomfort to the user's eyes caused by too fast brightness changes. The smooth transition of brightness can provide a more comfortable visual experience, especially when the ambient light conditions change, the user will not feel obvious brightness changes, reducing visual fatigue. The control system can adjust the brightness of the display screen according to the ambient light and user needs to avoid unnecessary energy consumption. For example, when the ambient light is strong, the brightness of the display screen can be appropriately reduced, and when the ambient light is weak, the brightness of the display screen can be appropriately increased to reduce the energy consumption of the backlight. The control system can obtain the current brightness based on software drive or the built-in light sensor of the display screen. This intelligent control method reduces manual intervention and improves the automation of the control system. The control system can automatically adjust the brightness of the display screen according to the change of the ambient light intensity, so that the display screen can maintain a good display effect under different lighting conditions, improving the adaptability of the display screen and the convenience of the user. By avoiding the display screen from working at the highest brightness for a long time, the loss of the display screen can be effectively reduced and its service life can be extended.
[0021] In summary, the embodiments of the present invention use vehicle-mounted automated expansion cabin technology to solve the problem that fixed billboards in related technologies 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: 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 the publicity is not restricted by geographical location.
[0022] Improved environmental adaptability: The design of the vehicle-mounted cabin takes into account the adaptability to the environment and can be used in various climatic conditions, thus ensuring the continuity and effectiveness of the publicity and maintaining the publicity effect even in harsh natural environments.
[0023] Convenience of content updating: The display screen and control system equipped in the vehicle-mounted cabin allow for rapid 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.
[0024] Intelligent brightness adjustment: The control system of the vehicle-mounted shelter can automatically adjust the brightness of the display screen based on factors such as ambient light intensity, time, and shelter location. This intelligent adjustment ensures good visual effects in different time periods and lighting conditions, and improves the visibility and attractiveness of promotional information.
[0025] Automation and remote control: The vehicle-mounted shelter can be operated by remote control, which reduces the need for on-site staff and reduces labor costs, while improving response speed and operational convenience, making publicity more efficient.
[0026] Versatility: In addition to being a publicity tool, the vehicle-mounted shelter can also be multifunctionally expanded as needed, such as being used as a temporary observation station, research station or rescue station, increasing its practicality in wildlife protection work.
[0027] Improved publicity: 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 increasing publicity in these areas.
[0028] 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.

[0031] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings and in combination with the embodiments.
[0032] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.
[0033] In this embodiment, a vehicle-mounted automated expansion cabin is provided. Figure 1 is a structural schematic diagram of a vehicle-mounted automation expansion cabin according to an embodiment of the present invention, such as Figure 1 As shown, the vehicle-mounted automated expansion cabin includes: a cabin shell 1, a display screen 2, and a control system 3. Among them, The cabin shell 1 is detachably connected to the rear of the vehicle head 4 and is provided with moving wheels; In an exemplary embodiment, the cabin shell 1 is a box-type structure, and maintenance tools for the display screen 2, spare display screens 2, etc. can be placed inside. Alternatively, daily necessities such as beds and drinking water can be placed inside to facilitate the duty personnel to keep watch, or to facilitate emergency avoidance of outdoor personnel. The cabin shell 1 is detachably connected to the front of the vehicle 4 through a hook. After the front of the vehicle 4 transports the cabin shell 1 to the target location, the front of the vehicle 4 can be separated from the cabin shell 1, and the cabin shell 1 can be left at the target location to display the publicity work of wildlife protection through the display screen 2. When it is necessary to move to other locations, for short-distance movement, the operator can use the moving wheels to move the cabin shell 1. For long-distance movement, the front of the vehicle 4 can be connected to the cabin shell 1 using a hook, so that the cabin shell 1 can be moved using the front of the vehicle 4 and the moving wheels. Alternatively, in order to improve the convenience of movement, both the front of the vehicle 4 and the cabin shell 1 can be left at the target location.
[0034] A display screen 2, detachably connected to the outer facade of the cabin shell 1; In an exemplary embodiment, the display screen 2 may be an LED display screen, an OLED display screen, etc. Micro LEDs, micron LEDs, mini LEDs, sub-millimeter LEDs, small-pitch LEDs, etc. may be used as light-emitting units. The display screen 2 may be installed at positions on both sides of the cabin shell 1 (such as Figure 1As shown in the figure), it can also be installed at the tail of the cabin shell 1, or, in order to improve the display effect, the display screen 2 can be installed on the top of the cabin shell 1. The installation position and installation angle of the display screen 2 and the cabin shell 1 can be relatively fixed, and a cylinder, hinge, etc. can be installed between the display screen 2 and the cabin shell 1 to facilitate changing the position and orientation angle of the display screen 2.
[0035] The control system 3 is used to adjust parameters, time, and the position of the cabin shell 1 based on the ambient light intensity, and obtain the target brightness to adjust the brightness of the display screen 2 based on the target brightness.
[0036] In an exemplary embodiment, the use scenario of the shelter is expanded in combination with the vehicle-mounted automation. For example, when the shelter shell 1 needs to be moved frequently, the vehicle head 4 and the shelter shell 1 can be left at the target location, and the control system 3 can be integrated into the central control system of the vehicle head 4. When the shelter shell 1 does not need to be moved frequently, only the shelter shell 1 can be left at the target location, and the control system 3 can also be installed inside the shelter shell 1.
[0037] To achieve 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 required to achieve this function and the information transmission method between them: Ambient light sensor: used to detect parameters such as the light intensity of the external environment, so as to obtain the ambient light intensity adjustment parameters. These sensors can be installed outside the cabin shell 1 to monitor the changes in ambient light in real time.
[0038] Display screen 2 brightness sensor: used to detect the current brightness of display screen 2 for comparison with the target brightness.
[0039] Control system 3: may include a microprocessor or microcontroller that runs a control algorithm to process sensor data and make decisions. For example, control system 3 may use a PID (proportional-integral-derivative) control algorithm to adjust the brightness of display screen 2 to adapt to changes in ambient light.
[0040] 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.
[0041] Interfaces: Sensors, control systems3 and actuators communicate with each other via electrical or wireless interfaces. These interfaces can be analog or digital, depending on the design of the system.
[0042] Power management unit: Provides stable power to sensors, control systems3 and actuators.
[0043] The information transmission process is as follows: The ambient light sensor detects changes in light intensity and sends the data to the control system 3.
[0044] The control system 3 calculates the ambient light intensity adjustment parameter based on the received ambient light data, and calculates the target brightness in combination with information such as time and the position of the cabin shell 1 .
[0045] The control system 3 sends the target brightness to the backlight control circuit of the display screen 2 .
[0046] The display 2 brightness sensor detects the current brightness and compares it with the target brightness.
[0047] If the current brightness is inconsistent with the target brightness, the control system 3 adjusts the backlight control circuit until the brightness of the display screen 2 reaches the target brightness.
[0048] In some embodiments, the control system 3 may also include other sensors, such as an inclination sensor (used to detect the horizontal state of the cabin) and a position sensor (used to determine the geographical location of the cabin so as to adjust the brightness of the display screen 2 according to the geographical location 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.
[0049] By adopting the above technical solution, the problem that fixed billboards in related technologies are difficult to achieve long-term effective publicity effects is solved by using vehicle-mounted automated expansion of the shelter, thereby achieving the effect of improving the publicity of wildlife protection in some remote areas or places with harsh conditions. Specifically: 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 the publicity is not restricted by geographical location.
[0050] Improved environmental adaptability: The design of the vehicle-mounted cabin takes into account the adaptability to the environment and can be used in various climatic conditions, thus ensuring the continuity and effectiveness of the publicity and maintaining the publicity effect even in harsh natural environments.
[0051] Convenience of content updating: The display screen 2 and control system 3 equipped in the vehicle-mounted shelter allow for rapid updating of promotional content. Through automated technical means, promotional information can be quickly adjusted remotely or on-site, thus improving the timeliness and flexibility of the promotion.
[0052] Intelligent brightness adjustment: The control system 3 of the vehicle-mounted shelter can automatically adjust the brightness of the display screen 2 based on factors such as ambient light intensity, time, and shelter location. This intelligent adjustment ensures good visual effects in different time periods and different lighting conditions, and improves the visibility and attractiveness of promotional information.
[0053] Automation and remote control: The vehicle-mounted shelter can be operated by remote control, which reduces the need for on-site staff and reduces labor costs, while improving response speed and operational convenience, making publicity more efficient.
[0054] Versatility: In addition to being a publicity tool, the vehicle-mounted shelter can also be multifunctionally expanded as needed, such as being used as a temporary observation station, research station or rescue station, increasing its practicality in wildlife protection work.
[0055] Improved publicity: 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 increasing publicity in these areas.
[0056] 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.
[0057] Figure 2 is a schematic diagram of the structure of a control system according to an embodiment of the present invention. In one implementation, Figure 2 As shown, the control system 3 includes: An acquisition module 31 is used to acquire the time and the position of the shelter shell 1; In an exemplary embodiment, the acquisition module 31 of the control system 3 can obtain the location information of the cabin from the GPS module built into the display screen 2, and obtain the sunrise and sunset times through the API of the weather station or the website. Alternatively, the location information, time and other information of the cabin can be obtained based on currently mature software and applications.
[0058] The algorithm module 32 is used to obtain the target brightness based on the following algorithm: L screen =min(L max ,max(L min ,L ′ screen *T*S*A*C)) Among them, L screen is the target brightness of display 2, L max is the maximum brightness threshold of display screen 2, L min is the minimum threshold of the brightness of 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.
[0059] In an exemplary embodiment, T is a time factor, which is calculated based on the sunrise and sunset times and is used to simulate the changes in light intensity at different times of the day. S is a location factor, which is obtained by real-time analysis using GPS and map data combined with image recognition technology and is used to distinguish between direct sunlight and shadows.
[0060] A is the environmental adaptability coefficient, which is used to consider the impact of different environments on the brightness of the display screen 2. It is a coefficient used to adjust the brightness of the display screen 2 to adapt to different environmental conditions. It takes into account the impact of environmental factors such as temperature, humidity, atmospheric pressure, etc. on the performance of the display screen 2. Under different environmental conditions, the brightness of the display screen 2 may be affected by changes in physical properties. For example, at high altitudes, 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 brightness according to these environmental changes to maintain the readability of the display screen 2. For example, if the cabin shell 1 is located at a high altitude, the value of the environmental adaptability coefficient can be increased to compensate for the reduced brightness perception due to the thin air.
[0061] C is a color correction factor, which is used to take into account the effect 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 effect 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 look more natural, while the same color may look different under indoor lighting. The color correction factor is used to adjust the color of the display screen 2 according to the ambient light to maintain color accuracy and consistency. For example, if the cabin shell 1 is used at dusk, the natural light at this time is warm-toned, and 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 lighting.
[0062] In summary, the algorithm module 32 calculates the product of the ambient light intensity adjustment parameter, the time factor, the position factor, the environmental adaptability coefficient, and the color correction factor to obtain a product value, compares the product value with the minimum threshold of the brightness of the display screen 2, selects the larger value between the two, compares the larger value with the maximum threshold of the brightness of the display screen 2, determines the smaller value between the two, and uses the smaller value as the target brightness of the display screen 2.
[0063] In one implementation, the ambient light intensity adjustment parameter is obtained based on the ambient light intensity.
[0064] In one implementation, the algorithm for calculating the ambient light intensity adjustment parameter is: L ′ screen=K* ; Among them, L ′ screen is the ambient light intensity adjustment parameter, K is the adjustment coefficient, L env is the ambient light intensity, α, is a nonlinear adjustment parameter.
[0065] In an exemplary embodiment, K is an adjustment coefficient, which may be a dynamic value based on historical ambient light data and performance optimization of the display screen 2, and is used to convert ambient light into screen brightness. env is the ambient light intensity, usually in lux, indicating the brightness of the ambient light where the display 2 is located. α is a nonlinear adjustment parameter, which is used to adjust the nonlinear response degree in the formula. This parameter can help adjust the adjustment speed of the brightness of the display 2 under different ambient light intensities. β is a nonlinear index, which determines the nonlinear degree of the effect of ambient light intensity on the brightness of the display 2. When the β value is large, it indicates that the brightness adjustment is more sensitive to changes in ambient light.
[0066] Specifically, regarding the denominator L env It means that by adding a constant α to adjust the numerator, the brightness adjustment can be reduced when the ambient light intensity is low to avoid the display 2 being too bright in a dark environment. Indicates that the value of this score will change with L env However, since α is included in the denominator, it limits the rate at which the fraction grows, thereby achieving nonlinear brightness adjustment.
[0067] Exponent β: By raising the fraction to the power of β, the nonlinear characteristics of the brightness response are further adjusted. If β is greater than 1, the nonlinear effect will be enhanced; if β is less than 1, the nonlinear effect will be weakened.
[0068] The above calculation result is multiplied by K: Finally, the above calculation result is multiplied by the adjustment coefficient K to obtain the final ambient light intensity adjustment parameter L ′ screen .
[0069] In this way, the brightness of the display 2 can be adjusted more finely and intelligently according to the ambient light intensity to provide a more comfortable visual experience and save energy.
[0070] In one embodiment, the vehicle-mounted automated expansion cabin further includes: Light sensor, used to obtain ambient light intensity; A GPS module is used to obtain the coordinate position of the shelter shell 1; A camera, used to obtain image data of the environment in which the cabin shell 1 is located; The control system 3 is also used to obtain a position factor based on the ambient light intensity, coordinate position, and image data.
[0071] In one embodiment, the control system 3 obtains the position factor based on the following algorithm: S=w Lenv *L env +w GPS *GPS+w I *I; Among them, w Lenv 、w GPS 、w I is a weight coefficient, GPS is the coordinate position of the cabin shell 1 obtained by the GPS module, and I is the image data of the environment in which the cabin shell 1 is located obtained by the camera.
[0072] In an exemplary embodiment, w Lenv 、w GPS 、w I is the weight coefficient, which can be obtained through experiments or machine learning algorithm optimization. The control system 3 filters and normalizes the ambient light intensity to obtain the ambient light intensity L env . Perform geocoding on the GPS data to obtain the location information of the cabin shell 1 relative to the surrounding environment to obtain the coordinate position GPS. Perform feature extraction on the image data captured by the camera, such as texture, color, shape, etc., to obtain image data I. Then, based on the above algorithm, perform geocoding on the processed L env , GPS, I calculate the position factor S.
[0073] In one embodiment, the control system 3 is further configured to compare the position factor with a preset threshold value to determine the shading condition.
[0074] In one embodiment, comparing the position factor with a preset threshold to determine the shading condition includes: When the position factor is less than or equal to the first threshold, it is determined that the cabin shell 1 is in a completely shaded environment; When the position factor is between the first threshold and the second threshold, it is determined that the shelter shell 1 is in a partially shaded environment; When the position factor is greater than or equal to the second threshold, it is determined that the cabin shell 1 is in an environment without sunshade; The preset threshold includes a first threshold and a second threshold, and the first threshold is smaller than the second threshold.
[0075] In an exemplary embodiment, when S≤T1, it indicates that the cabin shell 1 is in a completely shaded environment. When T1<S<T2, it indicates that the cabin shell 1 is in a partially shaded environment. When T2≤S, it indicates that it is in an unshaded environment. Therefore, through the above algorithm, the brightness of the display screen 2 can be automatically adjusted according to real-time environmental data to adapt to different shading conditions, thereby improving energy efficiency and user experience.
[0076] In one embodiment, the acquisition module 31 is further used to: acquire the current brightness of the display screen 2; The algorithm module 32 is further used to determine the direction and step length of brightness adjustment based on the current brightness and the target brightness, so as to adjust the current brightness to the target brightness based on the direction and the step length.
[0077] In one implementation, the control system 3 obtains the current brightness based on a software driver of the display screen 2 or a light sensor built into the display screen 2 .
[0078] In an exemplary implementation, adjusting the current brightness of the display screen 2 to the target brightness generally involves hardware control and software algorithms of the display screen 2. This process can be implemented by the following steps: Determine the current brightness: First, the current brightness value of the display screen 2 can be obtained through a built-in sensor of the display screen 2 or by querying the current setting of the display screen 2 through software.
[0079] Calculate brightness difference: Calculate the difference between the target brightness and the current brightness. This can be achieved by simple subtraction: ΔB = B target −B current Among them, B target is the target brightness, B current is the current brightness.
[0080] Determine the adjustment direction and step size: Determine whether to increase or decrease the brightness based on the brightness difference ΔB, and determine the step size for each adjustment. The step size can be set based on system requirements and user experience to ensure that the brightness adjustment is not too abrupt.
[0081] Adjust brightness gradually: Use a loop or timer to gradually adjust the brightness until the target brightness is reached. Each adjustment can be like this: B current =B current +ΔB*step. Where step is a positive number less than 1, indicating the percentage of each adjustment.
[0082] Use smooth transitions: To avoid discomfort caused by sudden brightness changes, you can use a gradual approach to adjust the brightness, such as using linear interpolation or more complex transition effects.
[0083] Feedback control: During the adjustment process, the actual brightness change can be monitored through the feedback mechanism to ensure the accuracy of the adjustment process. If the actual brightness deviates from the target brightness, fine-tuning can be performed.
[0084] Finish adjustment: When the current brightness is close enough to the target brightness (within an acceptable error range), stop the adjustment process.
[0085] It should be noted that the above modules can be implemented by software or hardware. For the latter, it can be implemented in the following ways, but not limited to: the above modules are all located in the same processor; or the above modules are located in different processors in any combination.
