Description

Technical Field

[0001] The invention relates to the technical field of LED display control, and more particularly to a self-adjusting system of an LED display screen. Background Art

[0002] LED display is a flat panel display, composed of small LED module panels, used to display text, images, videos and other information. Because LED display has high-intensity light emission, it can present high-definition display in different environments and has a wide viewing angle, so it has a wide range of applications in many fields.

[0003] With the increasing demand for intelligent interaction, many LED screens are used for publicity and display. For example, the current immersive exhibition halls and immersive VR experience halls will use LED screens on a large scale. However, during use, the LED display screens continue to work and display after being powered on. When displaying, the rated display brightness is often maintained. As a result, the brightness cannot be adjusted when different scenes need to be changed, and the display is still maintained when no one is watching. This not only causes continuous consumption of electricity, but also causes damage to the LED display screen components due to long-term power supply. Therefore, a system that can adjust the brightness of the LED display screen is urgently needed to achieve the effect of adjusting to the appropriate viewing brightness when there are people watching, and adaptively adjusting to the screen-off brightness when no one is watching. Summary of the invention

[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a self-adjusting system for an LED display screen, which has the effect of adjusting to a suitable viewing brightness when there are people watching, and adaptively adjusting to the screen-off brightness when there are no people watching.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A self-adjusting system for an LED display screen, comprising an input module, a detection module, a simulation module and an adjustment module;

[0007] The input module is configured with an input strategy, which includes inputting scene data for display in the LED display screen, retrieving the number and arrangement of the LED display screens, and allocating the scene arrangement in the scene data based on the number and arrangement of the LED display screens, so that the LED display screen fully displays the scene data;

[0008] The detection module is configured with a monitoring range threshold, a delay threshold and a detection strategy. The detection strategy includes setting a monitoring range threshold on both sides of the LED display screen, generating a display signal and a switching instruction when a viewer enters the monitoring range threshold, and identifying whether the viewer moves toward the LED display screen within the time range of the delay threshold. If the viewer moves toward the LED display screen, a switching instruction is sent to control the corresponding LED display screen to switch the scene display with scene data;

[0009] The simulation module is configured with a weather library, a simulation threshold and a simulation strategy. The simulation strategy includes, when a switching instruction is detected, retrieving real-time weather data, retrieving weather features corresponding to the weather data in the weather library and fitting them to the scene data to form a scene simulation under the corresponding weather, arranging the weather features in the weather library, and switching different weather features at the switching time according to the simulation threshold to perform scene simulation;

[0010] The adjustment module is configured with an adjustment strategy, which includes retrieving scene data, configuring basic brightness according to the scene data, the basic brightness representing the standard brightness value of the LED display when displaying, and when switching the scene exhibition, retrieving the arrangement of weather characteristics and simulation thresholds, generating corresponding adjustment thresholds according to the simulated weather characteristics, the adjustment threshold representing the adjustment value of the brightness of the LED display, and adjusting the brightness of the LED display based on the adjustment threshold when performing scene simulation.

[0011] As a further improvement of the present invention, the specific manner in which the entry strategy allocates scene data is as follows:

[0012] After calling the number and arrangement of LED display screens, the size of the LED display screens is also called, and the resolution of the scene data is adjusted based on the size of the LED display screen to satisfy the scene tiling in the scene data and the display on the LED display screen. A segmentation mark for segmenting the scene in the scene data is formed according to the size of the LED display screen, and the complete scene in the scene data is segmented into several sub-scenes based on the segmentation mark, and the sub-scenes are allocated in sequence along the arrangement of the LED display screen, so that the sub-scenes are displayed in sequence along the arrangement direction of the LED display screen.

[0013] As a further improvement of the present invention, the detection strategy also includes prediction logic, which is used to predict whether the viewer moves in the direction of the LED display screen. The monitoring range threshold includes an approach threshold and a prediction threshold. The approach threshold represents the range of the viewer entering the position close to the LED display screen, and the prediction threshold represents the range of determining whether the viewer moves in the direction of the LED display screen. The prediction logic includes:

[0014] When a viewer enters the approach threshold, a display signal is generated, and the moving direction of the viewer within the approach threshold is identified. If the moving direction is toward the predicted threshold direction, real-time monitoring is maintained. If the moving direction is outside the predicted threshold direction range, a rejection signal is generated to control the LED display to remain in its original state.

[0015] When the viewer enters the predicted threshold range, a switching instruction is generated to control the LED display screen to start displaying according to the scene data content and switch the scene in the scene data to be displayed on the LED display screen.

[0016] As a further improvement of the present invention, the weather data includes sunny days, cloudy days, overcast, haze, rainy days and bad weather. The weather library is preset with a priority order, and the priority order is from high to low: sunny days, rainy days, overcast, haze, overcast and bad weather. The simulation strategy is specifically:

[0017] The corresponding weather at the time of viewing is retrieved, and the weather data consistent with the real-time weather data in the weather library is retrieved, and the corresponding weather data is set as the highest priority, and the weather characteristics are rearranged according to the preset priority order to generate a weather sequence. The LED display screen simulates the corresponding weather simulation display in sequence according to the weather sequence.

[0018] As a further improvement of the present invention, the adjustment module is further configured with a time period strategy, and the adjustment module is further configured with a screen off brightness value, and the time period strategy includes:

[0019] Get the preset working time of the LED display, which includes power-on time, power-off time and rest period. At power-on time, the LED display is controlled to display according to the standard brightness value. During the rest period, the LED display is controlled to maintain the screen protection state according to the screen-off brightness value. At power-off time, the LED display is controlled to turn off.

[0020] As a further improvement of the present invention, the adjustment strategy is configured with frequency control logic and frequency threshold, the frequency threshold represents the number of times the LED display screen maintains viewing display within a unit day, and the frequency control logic includes:

[0021] Identify whether the number of times the LED display screen is viewed reaches the frequency threshold. If it reaches the frequency threshold, the corresponding LED display screen is classified into a high-frequency level. The LED display screen whose number of times the LED display screen is viewed is lower than the frequency threshold is classified into a low-frequency level. The LED displays in the high-frequency level and the low-frequency level are sorted in sequence according to the number of times they are displayed.

[0022] As a further improvement of the present invention, the adjustment module is further configured with a correction brightness, and the adjustment strategy specifically includes:

[0023] Identify the weather characteristics displayed by the LED display screen corresponding to the high frequency level, and adjust the brightness of the corresponding LED display screen by additionally correcting the brightness adjustment according to the adjustment threshold value generated by the weather characteristics;

[0024] For the LED display screen corresponding to the low-frequency level, the adjustment threshold generated by the corresponding weather characteristics is adjusted to adjust the brightness of the corresponding LED display screen.

[0025] As a further improvement of the present invention, the adjustment module is further configured with a screen-off threshold, which represents a time threshold when no one is watching the LED display screen. The adjustment strategy also includes:

[0026] If no one is watching the corresponding low-frequency level LED display within the screen-off threshold time, the corresponding LED display is controlled to adjust the brightness with the screen-off brightness value. When the detection strategy detects that there is a viewer within the monitoring range threshold, a start command is generated to control the LED display to start and adjust to the display brightness before the screen is turned off.

[0027] The beneficial effects of the present invention are as follows: scene data is entered into the system through the entry module, and the scene data is allocated according to the number and arrangement of LED display screens, so that the LED display screen can fully display the entered scene data, and whether there are viewers watching is identified under the action of the detection module, and the viewer's path is predicted, so that the scene data can be displayed when the viewer is watching, and the corresponding scenes in different weather environments are simulated by configuring the weather library in the simulation module, and the brightness of the LED display screen is adjusted according to the weather characteristics to be simulated, so as to achieve the effect of adaptively adjusting the brightness of the LED display screen when displaying.
