[0020] The screen partition adjustment module includes: Image recognition unit and area adjustment unit; Screen recognition unit: used to acquire the current display screen of the ruggedized display screen, scan the current display screen, and obtain screen content data; Content recognition is performed on the image content data to obtain a content data table, and the importance of the content data in the content data table is evaluated to obtain key content data and secondary content data; Extract the location distribution of key content data and secondary content data in the current display screen to obtain the key content area and secondary content area; Region adjustment unit: used to identify the key and secondary areas of key and secondary content areas; Based on the location of key areas, adjust the resolution and refresh rate of the key areas to the standard values; Based on the location of the secondary area, adjust the resolution and refresh rate of the secondary area to the preset minimum limit.

[0021] In application, taking a portable ruggedized display screen used in outdoor patrol missions as an example, the screen currently displays a map application screen. The screen recognition unit scans the map screen to obtain content data such as roads, buildings, and navigation points. Then, content recognition is performed on the content data to obtain a content data table, including road data as secondary content and navigation point data as primary content. The importance of the content data is then assessed: roads have an importance assessment value of 2, and navigation points have an importance assessment value of 8. The threshold is 5; values ​​above 5 are primary content, and values ​​below 5 are secondary content. Therefore, the primary content data is navigation points, and the secondary content data is roads. The positional distribution of the primary content data (navigation points) and secondary content (roads) on the screen is extracted. Navigation points are located in the center of the screen, and roads are located around the perimeter. Therefore, the primary content area is the central area, and the secondary content area is the surrounding area. The area adjustment unit identifies the location of key content areas as the middle coordinates (100,100) to (200,200), and the locations of secondary content areas as (0,0) to (100,100) and (200,200) to (300,300). Based on the location of the key area, the resolution at that location is adjusted from the default 1920x1080 to the standard value of 1920x1080 without changing the refresh rate, and the refresh rate is adjusted from the default 60Hz to the standard value of 60Hz without changing the refresh rate. Based on the location of the secondary area, the resolution at that location is adjusted from 1920x1080 to the lowest limit of 640x480, and the refresh rate is adjusted from 60Hz to the lowest limit of 30Hz.

[0022] The regional regulation unit includes: Resolution adjustment component and refresh rate adjustment component; Resolution adjustment component: used to identify the location of key areas and secondary areas, and generate a first resolution adjustment signal and a second resolution adjustment signal respectively; The first resolution adjustment signal is sent to the key area of ​​the screen, and the number of pixels displayed in the key area is adjusted to the standard value. The second resolution adjustment signal is sent to the secondary area of ​​the screen, and the number of pixels displayed in the secondary area is adjusted to the preset minimum limit. Refresh rate adjustment component: used to identify key and secondary areas and generate a first refresh rate adjustment signal and a second refresh rate adjustment signal respectively; The first refresh rate adjustment signal is sent to the key area of ​​the screen, and the number of times the pixels in the key area are refreshed per unit time is adjusted to the standard value. The second refresh rate adjustment signal is sent to the secondary area of ​​the screen, and the number of times the pixels in the secondary area are refreshed per unit time is adjusted to the preset minimum limit.

[0023] In application, taking a portable ruggedized display screen used in outdoor patrol missions as an example, the screen currently displays a task list. The area adjustment unit includes a resolution adjustment component and a refresh rate adjustment component. The resolution adjustment component identifies the location of the key content area, which is the upper left corner of the screen (50,50) to (150,150), and the secondary area is the rest of the screen. Then, it generates a first resolution adjustment signal and sends it to the key area, adjusting the number of pixels at that location from 1 million to the standard value of 1 million. Then, it generates a second resolution adjustment signal and sends it to the secondary area, adjusting the number of pixels at that location from 1 million to the minimum limit of 250,000. The refresh rate adjustment component identifies the key and secondary areas, with the key area remaining unchanged and the secondary area being the bottom of the screen. It generates a first refresh rate adjustment signal and sends it to the key area, adjusting the number of times the pixels at that location refresh per unit time from 60 times per second to the standard value of 60 times per second. Then, a second refresh rate adjustment signal is generated and sent to the secondary area, adjusting the refresh rate of pixels at that location from 60 times per second to the minimum limit of 20 times per second. After this processing, the power consumption of the secondary area is reduced by 40%, and the overall screen power consumption is reduced by 20%.

[0024] The screen display adjustment module includes: Image color recognition unit and backlight adjustment unit; Color recognition unit: used to scan the current display screen to obtain color distribution data on the reinforced display screen; Based on the color distribution data, extract the color area data and color region position of each color, and perform background recognition based on the color area data and color region position to obtain the background area in the currently displayed screen. Extract the display color from the background area, determine whether the display color is black, if the display color is black, generate the first backlight adjustment signal, if the display color is not black, generate the second backlight adjustment signal. Backlight adjustment unit: used to receive a first backlight adjustment signal or a second backlight adjustment signal. If the received signal is the first backlight adjustment signal, the backlight in the background area is turned off according to the first backlight adjustment signal. If the received signal is a second backlight adjustment signal, the backlight in the background area is adjusted to the preset minimum value according to the second backlight signal.

[0025] In application, taking a portable ruggedized display screen used in outdoor patrol missions as an example, the screen currently displays a weather forecast application. The screen color recognition unit of the screen image adjustment module scans the current display screen to obtain color distribution data, including blue sky accounting for 60%, green trees accounting for 30%, and white text accounting for 10%. Then, it extracts the color area data for each color: blue area is 300 square pixels, located at the top of the screen; green area is 150 square pixels, located at the bottom of the screen. Based on the color area data and location, background recognition is performed. The larger blue and green areas are the background, indicating that the background areas are the top and bottom areas. The display color in the background area is extracted. Since blue is not black and green is not black, it is determined that the display color is not black, generating a second backlight adjustment signal. The backlight adjustment unit receives the second backlight adjustment signal and adjusts the backlight brightness in the background area from the standard value of 200 nits to the preset minimum value of 50 nits. After this processing, the backlight power consumption in the background area is reduced by 75%.

[0026] The function block adjustment module includes: Functional domain status recognition unit and power-on / off operation unit; Functional domain status recognition unit: used to identify and divide the functions of the ruggedized display screen to obtain multiple functional blocks; Obtain the current working status of the ruggedized display screen, and determine whether each functional block needs power based on the current working status; If it is determined that the functional block does not require power, a power-down signal is generated; if it is determined that the functional block requires power, a power-on signal is generated. Power-on / off operation unit: used to power on and off different functional blocks according to power-on and power-off signals.

[0027] In application, taking a portable ruggedized display screen used in outdoor patrol missions as an example, the display screen is currently in standby mode. The functional domain state recognition unit of the functional block adjustment module identifies and divides the display screen's functions, obtaining multiple functional blocks: Bluetooth block, GPS block, and screen display block. Then, it obtains the current working state as standby mode. Based on the current working state, it determines whether each functional block requires power: Bluetooth does not require power, GPS does not require power, and the screen display requires power. If the Bluetooth block does not require power, a power-down signal is generated; if the GPS block does not require power, a power-down signal is generated; if the screen display block requires power, a power-on signal is generated. The power-on / off operation unit operates according to the power-on and power-off signals: powering down the Bluetooth block, turning off the power; powering down the GPS block, turning off the power; and powering on the screen display block, keeping the power on. After this processing, the power consumption of Bluetooth and GPS drops to 0, and the overall device power consumption is reduced by 30%.

[0028] The historical data analysis module includes: Data analysis unit and power consumption parameter unit; Data analysis unit: used to acquire historical usage data and current usage environment of ruggedized display screens, filter historical usage data based on the current usage environment, and obtain target historical data corresponding to historical time periods that are consistent with the current usage environment; Based on the target's historical data, extract the historical screen operation data from the target's historical data, and obtain the number of screen operations and the screen operation area based on the historical screen operation data. Power consumption parameter unit: used to obtain the historical power consumption components of the ruggedized display and the historical power consumption frequency of each historical power consumption component based on the number of screen operations and the screen operation area; Historical power consumption parameters are obtained based on historical power consumption components and historical power consumption frequencies. These historical power consumption components and historical power consumption frequencies are then optimized and identified to obtain optimizable power consumption parameters. By combining the historical power consumption parameters and the optimizable power consumption parameters, power consumption adjustment parameters are generated.

[0029] In this application, taking a portable ruggedized display screen used in an outdoor patrol mission as an example, the current operating environment is high-temperature outdoor. The historical data analysis module's data analysis unit acquires historical usage data of the display screen, including records from the past three months and the current operating environment temperature of 35 degrees Celsius. Based on the current operating environment, the historical usage data is filtered to obtain target historical data for a temperature of 35 degrees Celsius, i.e., the record from last month. Based on the target historical data, historical screen operation data is extracted, including 50 user clicks, with the operation area mainly in the center of the screen. The power consumption parameter unit, based on the 50 screen operation counts and the central operation area, identifies the historical power-consuming components: the central processing unit (CPU) and the screen backlight. The historical power consumption frequency for each component is: CPU frequency 50%, screen backlight frequency 70%. Based on the historical power-consuming components and frequencies, the average historical power consumption parameter is 10 watts. Further optimization identification of the historical power-consuming components reveals that the screen backlight has a high frequency but can be optimized, resulting in an optimizable power consumption parameter of reducing backlight brightness. Combining the historical power consumption parameter of 10 watts and the optimizable parameter, the power consumption adjustment parameter is to reduce the backlight brightness by 50%.

[0030] The adaptive adjustment module includes: Operation recording unit and instruction adjustment unit; Operation recording unit: used to record user operations on the ruggedized display screen within a certain period of time, identify the validity of the human operations, obtain valid human operations, and generate an operation record table based on the valid human operations; Command adjustment unit: used to identify the operation log table, obtain the operation time interval between each valid human operation and the power consumption delay length of each valid human operation on each functional block in the ruggedized display screen; Based on the operation time interval and power consumption delay length, the power supply direction and power supply of the ruggedized display screen are predicted to obtain the predicted power supply direction and predicted power supply. The system generates a work-rest instruction set based on the predicted power supply direction, predicted power supply amount, and power consumption adjustment parameters, and then adaptively adjusts the power consumption of the ruggedized display screen according to the work-rest instruction set.

[0031] In application, taking a portable ruggedized display screen used in outdoor patrol missions as an example, a user is operating the display screen to view a map. The adaptive adjustment module's operation recording unit records the user's human operations over a period of time: clicks, swipes, etc. The validity of these human operations is identified, with valid human operations being clicks on navigation points and invalid operations being accidental touches on edges; valid operations are retained. An operation record table is generated based on the valid human operations, including three click operations. The instruction adjustment unit identifies the operation record table, obtaining the operation time interval between each valid operation: 10 seconds between the first and second clicks, and 15 seconds between the second and third clicks. The power consumption delay length of each valid operation on the functional blocks is also determined: a 2-second delay for the central processing unit (CPU) and a 5-second delay for the backlight. Based on the operation time interval and power consumption delay length, the predicted power supply direction prioritizes the CPU, with a predicted power supply of 5 watts for the CPU and 3 watts for the backlight. Combined with the power consumption adjustment parameter of reducing the backlight brightness by 50%, a work-rest instruction set is generated: the work instruction supplies 5 watts to the CPU for 2 seconds, and the rest instruction reduces the backlight brightness by 50% for 5 seconds. Then, the power consumption of the display is adaptively adjusted according to the instruction set: the screen is on when working and in sleep mode when resting. After this processing, the battery life is extended by 25%.

[0032] The operation recording unit includes: Recording components and effectively identifying components; Recording component: Used to record user actions on the ruggedized display screen over a period of time; Effective recognition component: used to identify recorded human operations, obtain the screen contact area and screen contact force of each human operation during the operation process, as well as the original and result images on the screen before and after each human operation; Determine if there is a logical relationship between the time of the original image and the result image. If no logical relationship is found, the manual operation is marked as invalid and the record is deleted. If a logical connection is determined, the screen contact area and the screen contact force are combined to further determine whether the human operation is valid. If it is determined to be invalid, the record is deleted. If the operation is determined to be valid, the human operation will be retained and an operation record table will be generated.

[0033] In application, taking a portable ruggedized display screen used in outdoor patrol missions as an example, the user operates the display screen to input data. The recording component of the operation recording unit records human operations within a certain period: five screen touches. The valid recognition component identifies each operation, obtaining the screen contact area as 50 square millimeters for the first touch, the screen contact force as 5 Newtons for the first touch, the original image as a map, and the result image as a magnified map. It is determined that there is a logical connection between the original map image and the magnified result image, because the operation is a magnification action. Combining the screen contact area of ​​50 square millimeters and the contact force of 5 Newtons, a normal operation area should be greater than 40 square millimeters, and the force should be greater than 3 Newtons, thus determining the operation as valid. Invalid operation records are deleted. The operation is retained, generating an operation record table. After this processing, invalid operations are reduced by 80%, and the operation recording accuracy is improved to 95%.
