Description

Technical Field

[0001] The present application relates to the technical field of LED display screens, and in particular to a direct current power supply method and power supply system for an LED box and a wallpaper display screen. Background Art

[0002] With the development of display technology, wallpaper displays, as a new type of display device, are gaining increasing attention due to their lightweight, thin design and wall-mountable design. Wallpaper displays are typically composed of multiple LED cabinets, which place high demands on the power supply to ensure display quality and stability.

[0003] Currently, traditional LED power supply methods mostly use a method of converting AC to DC. However, for wallpaper displays, which strive for a slim design, the introduction of AC not only increases the size and complexity of the power supply system but also creates problems such as electromagnetic interference, affecting the overall performance and aesthetics of the wallpaper display. Related technologies have improved this traditional power supply method by directly powering the LED cabinet with 24V DC, significantly reducing the size of the device and reducing electromagnetic interference and other issues.

[0004] However, in the related art, when the LED box is powered, the wallpaper display screen is usually kept at a fixed display brightness and display color. However, different user situations have different requirements for display brightness and display color, so it is difficult to meet user needs. Summary of the Invention

[0084] In a first aspect, the present application discloses a DC power supply method for an LED box.

[0085] Reference Figure 1 A DC power supply method for an LED box includes steps S101 to S104:

[0086] Step S101: obtaining the current natural environment and the current human environment corresponding to the LED box at the current time node.

[0087] Specifically, in this embodiment, the current natural environment is the natural environment in the area where the LED box is located at the current time node, including illumination and noise level, etc.; the current human environment is the human environment in the area where the LED box is located at the current time node, including human identity information, number of people, and human action information, etc.

[0088] Step S102: Based on the current natural environment, obtain a first display brightness and a first display color.

[0089] Specifically, in this embodiment, a control system is provided in the LED box, which can intelligently select appropriate display brightness and display color according to the current natural environment of the area where the LED box is located. This not only helps users to clearly see the display content on the wallpaper display screen and improve user experience, but also helps to reduce the wallpaper display screen from maintaining a fixed display brightness and display color, resulting in waste of resources and the like; wherein, the first display brightness is the adaptive display brightness automatically adjusted by the control system according to the current natural environment, and the first display color is the adaptive display color automatically adjusted by the control system according to the current natural environment; it is worth noting that the control system can intelligently adjust the display brightness and display color of the wallpaper display screen, and different display brightness and display colors correspond to different powers. Therefore, by adjusting the display brightness and display color of the wallpaper display screen, the power consumption of the wallpaper display screen can be adjusted.

[0090] Step S103: Based on the current character environment, the first display brightness and the first display color, a second display brightness and a second display color are acquired.

[0091] Specifically, in this embodiment, the second display brightness is the display brightness obtained by adjusting the first display brightness according to the current character environment; the second display color is the display color obtained by adjusting the first display color according to the current character environment.

[0092] Step S104: obtaining a supply voltage based on the second display brightness and the second display color.

[0093] Specifically, in this embodiment, obtaining the power supply voltage according to the second display brightness and the second display color includes the following steps:

[0094] 1. Establish a mapping relationship:

[0095] (1) Collect a large amount of experimental data covering different display brightness, colors and their corresponding power supply voltages; (2) Use this data to construct a mapping table or function to reflect the relationship between display brightness, color and power supply voltage.

[0096] 2. Color space conversion:

[0097] Convert the second display color from the common RGB color space to the HSV color space. This is because in the HSV color space, brightness (V) and saturation (S) can more intuitively reflect the characteristics of the color.

[0098] 3. Brightness and color feature extraction:

[0099] (1) Extract brightness (V) and saturation (S) from the converted HSV color space; (2) Fuse the second display brightness with the color brightness (V) to form a comprehensive brightness index.

[0100] 4. Query mapping relationship:

[0101] According to the comprehensive brightness index and the color saturation (S), the corresponding power supply voltage is found in the mapping table or function.

[0102] 5. Corrections and adjustments:

[0103] Taking into account the characteristics of the LED cabinet, ambient temperature and other factors, the found power supply voltage is corrected and adjusted.

[0104] 6. Output results:

[0105] Finally, a power supply voltage suitable for the current second display brightness and second display color is obtained.

[0106] The DC power supply method based on the LED box provided in this embodiment first obtains the current natural environment and the current human environment corresponding to the LED box at the current time node, and obtains the first display brightness and the first display color adapted to the current natural environment according to the current human environment, and then combines the current human environment with the first display brightness and the first display color, and adjusts the first display brightness and the first display color according to the current human environment, so as to obtain the second display brightness and the second display color suitable for the current task environment under the current natural environment, and finally obtains the power supply voltage according to the second display brightness and the second display color; by combining the current natural environment and the current human environment, the second display brightness and the second display color suitable for the combination of the current natural environment and the current human environment are selected, which helps to improve user satisfaction with the display brightness and display color.

[0107] Reference Figure 2 In one implementation of this embodiment, step S103 acquires the second display brightness and the second display color based on the current character environment, the first display brightness, and the first display color, including steps S201 to S207:

[0108] Step S201: Acquire information of people in the target area.

[0109] Specifically, the target area is the area where the LED box is located. If the LED box is installed indoors, the target area can be the space inside the room. If the LED box is installed outdoors, the target area can be a spherical area with a radius of 5 meters and the LED box as the center. The personnel information is the relevant information of the people entering the target area, including personal identity information, height, weight, appearance, age, physical condition, preferences, etc. In this embodiment, an omnidirectional camera device is installed on the wallpaper display screen to capture people entering the target area.

[0110] Step S202: If no personnel information is detected, obtain the idle time of the personnel in the target area.

[0111] Specifically, in this embodiment, the personnel idle time is the average length of time during which no personnel enter the target area.

[0112] Step S203: Obtain historical detection time of personnel information.

[0113] Specifically, in this embodiment, the historical detection time is the time when a person was last detected to enter the target area.

[0114] Step S204: Based on the historical detection time, the current time node and the personnel's idle time, obtain the idle remaining time.

[0115] Specifically, the idle remaining time is the remaining time when no person enters the target area. In this embodiment, the idle remaining time=personnel idle time-(current time node-historical detection time).

[0116] Step S205: If the idle remaining time is greater than or equal to the first time threshold, obtaining a second display brightness and a second display color based on the standby mode.

[0117] Specifically, the first time threshold is a pre-set judgment standard for determining whether the idle remaining time is too long. In this embodiment, the first time threshold can be 1 hour or other time; when the idle remaining time is greater than or equal to the first time threshold, it means that the idle remaining time is too long, that is, no one will enter the target area for a long time in the future, so the wallpaper display screen can be adjusted to standby mode to reduce the consumption of power resources, where the standby mode is a low-power operating state when the main work task is not performed.

[0118] Step S206: If the idle remaining time is less than or equal to the second time threshold, obtaining a second display brightness and a second display color based on the first display brightness and the first display color.

[0119] Specifically, the second time threshold is a pre-set judgment standard for determining whether the remaining idle time is too short. In this embodiment, the second time threshold can be 10 minutes or other time. It is worth noting that the first time threshold is greater than the second time threshold; when the remaining idle time is less than or equal to the second time threshold, it means that someone will soon enter the target area, so there is no need to make other adjustments to the display brightness and display color of the wallpaper display screen, and the first display brightness and the first display color are directly used as the second display brightness and the second display color.

[0120] Step S207: If the remaining idle time is greater than the second time threshold and less than the first time threshold, a second display brightness and a second display color are obtained based on the low-brightness mode.

[0121] Specifically, in this embodiment, if the remaining idle time is greater than the second time threshold and less than the first time threshold, it means that no one will enter the target area in a short time, but someone will enter after a little longer time. Therefore, the display brightness and display color can be appropriately adjusted to put it in low-brightness mode, which not only helps to reduce power consumption, but also helps to prevent frequent opening and closing of the wallpaper display screen, thereby affecting the service life of the wallpaper display screen; wherein, the second display brightness corresponding to the low-brightness mode can be directly set to 30% of the first display brightness, and the second display color corresponding to the low-brightness mode can be set to a darker tone than the first display color; the display brightness and display color corresponding to the low-brightness mode can also be directly pre-set. When the low-brightness mode is selected, the second display color and the second display brightness are directly set according to the display brightness and display color pre-set for the low-brightness mode.

[0122] The DC power supply method based on the LED box provided in this embodiment, if no personnel information is detected, it means that no personnel has entered the target area, and further obtains the idle time and historical detection time of the personnel in the target area, so as to calculate the remaining idle time in the target area, and then judges the size relationship between the remaining idle time and the first time threshold and the second time threshold, so as to obtain the corresponding second display brightness and second display color according to the actual situation, which helps to improve the user's satisfaction with the display brightness and display color.

[0123] Reference Figure 3 In one implementation of this embodiment, after obtaining the personnel information in the target area in step S201, steps S301 to S308 are also included:

[0124] Step S301: If personnel information is detected, it is determined whether designated personnel information exists in the personnel information.

[0125] Specifically, the designated personnel information is the personnel information corresponding to the designated personnel. In this embodiment, the personnel information of the designated personnel can be pre-entered into the relevant system. After the personnel information is obtained, the personnel information is matched with the pre-entered personnel information. When the match is successful, it indicates that the designated personnel information exists in the personnel information.

[0126] Step S302: If there is designated personnel information, the number of personnel is obtained based on the personnel information.

[0127] Specifically, the number of people is the number of people entering the target area.

[0128] Step S303: If the number of personnel is equal to 1, a designated mode is obtained based on the designated personnel information.

[0129] Specifically, in this embodiment, if the number of people is equal to 1, it means that only one person enters the target area, and the person must be a designated person, so according to the designated person information of the designated person, the corresponding display mode is obtained, and the display mode is the designated mode. It is worth noting that the designated mode is a display mode personalized according to the designated person information, and the designated modes corresponding to different designated person information may also be different.

[0130] Step S304: Based on the first display brightness, the first display color, and the specified mode, obtain a second display brightness and a second display color.

[0131] Specifically, in this embodiment, the display brightness and display color suitable for the designated person can be obtained according to the designated mode, and then the first display brightness and the first display color are combined to generate the final second display brightness and the second display color.

[0132] Step S305: If the number of personnel is greater than 1, determine whether the number of personnel is equal to the specified number.

[0133] Specifically, in this embodiment, if the number of people is greater than 1, it means that there is more than one person entering the target area, and it is further determined whether the number of people is equal to the specified number, so as to determine whether the people entering the target area are all designated people, where the specified number is the number of designated people entering the target area.

[0134] Step S306: If the number of personnel is equal to the designated number, priority display levels of different designated personnel are obtained based on the personnel information.

[0135] Specifically, in this embodiment, if the number of people is equal to the specified number, it means that the people entering the target area are all designated people, and can be set according to the priority display level of the designated people, so as to further obtain the priority display level of different designated people, wherein the priority display level is the display level of priority adaptation. The higher the priority display level, the second display brightness and the second display color of the wallpaper display screen will be adapted to the personnel information of the designated person first.

[0136] Step S307: Based on the priority display level, obtain the highest display level.

[0137] Specifically, in this embodiment, the highest display level is the highest priority display level among the priority display levels of all designated persons who enter the target area.

[0138] Step S308: Based on the first display brightness, the first display color, and the highest display level, obtain a second display brightness and a second display color.

[0139] Specifically, in this embodiment, the display brightness and display color suitable for the designated person with priority adaptation can be obtained according to the highest display level, and then combined with the first display brightness and the first display color to generate the final second display brightness and the second display color.

[0140] The DC power supply method based on the LED box provided in this embodiment determines whether there is designated personnel information in the personnel information. If so, the number of personnel is further obtained and it is determined whether the number of personnel is equal to 1. If it is equal to 1, the corresponding designated mode is generated according to the personnel information of the designated personnel, and the final second display brightness and second display color are generated by combining the designated mode, the first display brightness and the first display color; if it is greater than 1, it is further determined whether the number of personnel is equal to the designated number. If they are equal, the highest display level among different designated personnel is further obtained, and the final second display brightness and second display color are generated by combining the highest display level, the first display brightness and the first display color; selecting a more targeted method to obtain the corresponding second display color and second display brightness according to different situations helps the second display color and second display brightness to better meet user requirements, thereby helping to improve user satisfaction with the display brightness and display color.

[0141] Reference Figure 4 In one implementation of this embodiment, step S308 acquires the second display brightness and the second display color based on the first display brightness, the first display color, and the highest display level, including steps S401 to S404:

[0142] Step S401 : if the highest display level is the designated display level, obtaining a second display brightness and a second display color based on the first display brightness, the first display color, and the highest display level.

[0143] Specifically, in this embodiment, the designated display level is a preset display level. In this embodiment, the designated display level can be set to the priority display level of the top 1% of all designated persons.

[0144] Step S402: If the highest display level is not the designated display level, obtain the level difference between the highest display level and the second highest display level.

[0145] Specifically, in this embodiment, the second highest display level is the second priority display level among the priority display levels of all designated persons entering the target area, and the level difference is the difference obtained by subtracting the second highest display level from the highest display level.

[0146] Step S403: If the level difference exceeds the level difference threshold, obtaining a second display brightness and a second display color based on the first display brightness, the first display color, and the highest display level.

[0147] Specifically, in this embodiment, if the level difference exceeds the level difference threshold, it means that the level gap between the highest display level and the second highest display level is large. Therefore, it is necessary to prioritize the adaptation of the personnel information of the designated person corresponding to the highest display level, and then combine the first display brightness, the first display color and the highest display level to generate the second display brightness and the second display color, wherein the level difference threshold level is used as a criterion for judging whether the level difference is too large.

[0148] Step S404: If the level difference does not exceed the level difference threshold, obtaining a second display brightness and a second display color based on the first display brightness and the first display color.

[0149] Specifically, in this embodiment, if the level difference does not exceed the level difference threshold, it means that the level gap between the highest display level and the second highest display level is large. Therefore, the personnel information of the designated person corresponding to the highest display level cannot be adapted first. Instead, most or even all designated persons must be taken into consideration. Therefore, the display is directly performed according to the first display brightness and the second display brightness.

[0150] The DC power supply method based on the LED box provided in this embodiment, if the highest display level is the specified display level, then the second display brightness and the second display color are obtained based on the first display brightness, the first display color and the highest display level; if the highest display level is not the specified display level, then the level difference between the highest display level and the second highest display level is obtained, and it is judged whether the level difference exceeds the level difference threshold; if it exceeds, then the second display brightness and the second display color are obtained based on the first display brightness, the first display color and the highest display level; if it does not exceed, then the second display brightness and the second display color are obtained based on the first display brightness and the first display color; first judge whether the highest display level is the specified display level, and then judge whether the level difference exceeds the level difference threshold. After double judgment, the corresponding method is selected according to the judgment result to obtain the second display brightness and the second display color, so as to help the obtained second display brightness and the second display color better meet user needs.

[0151] Reference Figure 5 In one implementation of this embodiment, if the number of personnel is greater than 1 in step S305, then after determining whether the number of personnel is equal to the specified number, steps S501 to S507 are further included:

[0152] Step S501: If the number of people is not equal to the specified number, the position distribution and action characteristics of different people are obtained.

[0153] Specifically, if the number of people is not equal to the designated number, it means that there must be non-designated people among the people entering the target area, and the positions and action characteristics of different people are further obtained. In this embodiment, the position distribution is the distribution of the positions of all people. Through the position distribution, the status or importance of these people can be roughly obtained. In this embodiment, generally speaking, the closer the position is to the middle, the higher the status of the person or the higher the importance of this time; the action characteristics are the actions performed by each person.

[0154] Step S502: Based on the station distribution, obtain the personnel at the central station.

[0155] Specifically, in this embodiment, the central standing personnel are personnel standing at the most central position.

[0156] Step S503: Determine whether there are multiple personnel at the central station.

[0157] Step S504: If there are not multiple central station personnel, determine whether the central station personnel is a designated personnel.

[0158] Step S505: If the person standing at the center is not a designated person, a second display brightness and a second display color are obtained based on the first display brightness and the first display color.

[0159] Specifically, in this embodiment, if the person standing at the center is not a designated person, it means that the person standing at the center is an outsider, which also means that the outsider is the person with the highest status among this group of people or the most important person in this trip. In order to better meet their needs, the display brightness and display color cannot be adjusted according to the priority display level or designated mode. Therefore, the first display brightness and the first display color are directly used as the second display brightness and the second display color.

[0160] Step S506: If the person standing at the center is the designated person, whether the designated person is a guide is determined based on the action characteristics.

[0161] Specifically, if the person at the center station is a designated person, then that person is the designated person. To determine whether the designated person is the highest-ranking person in the group or the most important person on the trip, the designated person's motion characteristics are further used to determine whether he or she is a guide. In this embodiment, a guide is someone who guides or introduces others to others, so he or she is not the highest-ranking person in the group or the most important person on the trip, while the person he or she guides is the highest-ranking person in the group or the most important person on the trip. Whether he or she is a guide can be determined based on guiding gestures or introduction gestures. In this embodiment, a large amount of data is pre-trained using a machine learning language, which helps to accurately determine whether a designated person is a guide based on their motion characteristics.

[0162] Step S507: If the designated person is a guide, a second display brightness and a second display color are obtained based on the first display brightness and the first display color.

[0163] Specifically, in this embodiment, if the designated person is a guide, it means that the person with the highest status among the group of people or the most important person in this trip is still an outsider, so the method of obtaining the second display brightness and the second display color is consistent with step S505.

[0164] The DC power supply method based on the LED box provided in this embodiment obtains the standing position distribution and action characteristics of different personnel, and obtains the central standing personnel based on the standing position distribution and action characteristics, and selects the corresponding method to obtain the second display brightness and the second display color according to whether the central standing personnel is a designated person, thereby helping to improve user satisfaction with the display brightness and display color.

[0165] Reference Figure 6 In one implementation of this embodiment, steps S601 to S605 are further included:

[0166] Step S601: Based on the personal information of the designated person, the life pattern of the designated person is obtained.

[0167] Specifically, in this embodiment, the life pattern includes working time, rest time, entertainment time, and preferences corresponding to work, entertainment, and rest time.

[0168] Step S602: Based on the life pattern, obtain the time range that the designated person is in the target area.

[0169] Step S603: Determine whether other personnel information is detected within the time range.

[0170] Step S604: If no other personal information is detected, a specified pattern is obtained based on life patterns.

[0171] Step S605: Obtain the supply voltage based on the specified mode.

[0172] The DC power supply method based on the LED box provided in this embodiment first obtains the life pattern of the designated person according to the personal information of the designated person, and then obtains the time range of the designated person in the target area according to the life pattern. When no other people are detected within the time range, the corresponding designated mode is directly obtained according to the life pattern of the designated person, and finally the corresponding power supply voltage is obtained according to the designated mode; selecting the corresponding designated mode for power supply according to the life pattern of the designated person helps the display color and display brightness to be more in line with the life habits of the designated person, which not only helps to reduce energy consumption, but also helps to improve user satisfaction.

[0173] Reference Figure 7 In one implementation of this embodiment, after determining whether other personnel information is detected within the time range in step S603, the process further includes steps S701 to S705:

[0174] Step S701: If other personnel information is detected, it is determined whether a mode adjustment instruction is detected.

[0175] Specifically, in this embodiment, the mode adjustment instruction is an instruction for intelligently adjusting the current mode according to the current actual situation. The instruction can be sent through an instruction button, such as a remote control.

[0176] Step S702: If a mode adjustment instruction is detected, the character features are obtained.

[0177] Specifically, in this embodiment, character features include all features corresponding to all characters.

[0178] Step S703: Based on the character features, obtain the current matching mode.

[0179] Specifically, the current matching mode is a display mode suitable for the current situation. For example, if the character's characteristic is gentle dancing, the current matching mode may be a soothing mode, which indicates a mode with softer display brightness and color.

[0180] Step S704: Based on the current matching mode, obtain matching color and matching brightness.

[0181] Specifically, the matching color is the color corresponding to the current matching mode, and the matching brightness is the brightness corresponding to the current matching mode.

[0182] Step S705: obtaining a supply voltage based on the matching color and the matching brightness.

[0183] The DC power supply method based on the LED box provided in this embodiment, when a mode adjustment instruction is detected, indicates that the wallpaper display screen will intelligently adjust the display brightness and display color according to the current environment to adapt, further obtain the character characteristics, and obtain the current matching mode based on the character characteristics, and then obtain the corresponding matching color and matching brightness based on the current matching mode, and finally obtain the power supply voltage based on the matching color and matching brightness; when the mode adjustment instruction is detected, the system will select the corresponding mode for matching according to the character characteristics in the current situation, so that the color and brightness displayed by the wallpaper display screen are more adapted to the action characteristics, thereby helping to improve user satisfaction.

[0184] Reference Figure 8 In one implementation of this embodiment, step S703 obtains the current matching mode based on the character features, including steps S801 to S806:

[0185] Step S801: Based on the character characteristics, obtain the character's health characteristics, character movement characteristics, and character status characteristics.

[0186] Specifically, in this embodiment, the character health characteristics refer to the character's health status, including historical medical history, etc.; the character action characteristics refer to all actions performed by the person; and the character state characteristics refer to the person's state, such as stillness and movement.

[0187] Step S802: Obtain health mode options based on the person's health characteristics.

[0188] Specifically, in this embodiment, the health mode option is a display mode formulated according to the task health characteristics of all personnel.

[0189] Step S803: Obtain matching mode options based on the character's action features.

[0190] Specifically, in this embodiment, the matching mode option is a display mode formulated according to the character action characteristics of all people.

[0191] Step S804: Acquire status mode options based on the character status characteristics.

[0192] Specifically, in this embodiment, the status mode option is a display mode formulated according to the status characteristics of all personnel.

[0193] Step S805: Based on the health mode option, the matching mode option and the status mode option, a target mode is obtained.

[0194] Specifically, in this embodiment, the target mode is the final display mode generated by integrating the health mode option, the matching mode option, and the status mode option.

[0195] Step S806: Acquire the supply voltage based on the target mode.

[0196] The DC power supply method based on the LED box provided in this embodiment obtains the character's health characteristics, character movement characteristics and character status characteristics according to the character's characteristics, and then integrates the health mode options, matching mode options and status mode options to generate the final display mode, which helps the target mode to better meet the needs of more users, thereby improving user satisfaction.
