Description

Technical Field

[0002] With the development of display technology, as a new type of display device, the wallpaper display screen has received more and more attention due to its characteristics such as being thin, light, and attachable to the wall. The wallpaper display screen is usually composed of multiple LED box bodies. To ensure its display effect and stability, high requirements are put forward for the power supply of the LED box bodies.

[0003] Currently, traditional LED power supply methods mostly use the method of converting alternating current into direct current. However, for a device like the wallpaper display screen that pursues a thin and light design, the introduction of alternating current not only increases the volume and complexity of the power supply system, but also has problems such as electromagnetic interference, affecting the overall performance and aesthetics of the wallpaper display screen. Related technologies have improved the traditional power supply method and directly used 24V direct current to supply power to the LED box body, which not only greatly reduces the volume of the device, but also reduces problems such as electromagnetic interference.

[0004] However, in related technologies, when supplying power to the LED box body, the wallpaper display screen usually maintains 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

[0021] In a first aspect, the present application discloses a DC power supply method for an LED box body.

[0022] Referring to Figure 1 , a DC power supply method for an LED box body includes steps S101 to S104: Step S101: Obtain the current natural environment and current human environment corresponding to the LED box body at the current time node.

[0023] Specifically, in this embodiment, the current natural environment is the natural environment in the area where the LED box body is located at the current time node, including illuminance and noise level, etc.; the current human environment is the human environment in the area where the LED box body is located at the current time node, including personal identity information, the number of people, and human action information, etc.

[0024] Step S102: Based on the current natural environment, obtain the first display brightness and the first display color.

[0025] Specifically, in this embodiment, a control system is provided in the LED box body. The control system will intelligently select appropriate display brightness and display color according to the current natural environment of the area where the LED box body is located, which not only helps users to clearly see the display content on the wallpaper display screen and improves the user experience, but also helps to reduce the occurrence of resource waste caused by the wallpaper display screen maintaining a fixed display brightness and display color; among them, the first display brightness is the display brightness adaptively adjusted by the control system according to the current natural environment, and the first display color is the display color adaptively adjusted by the control system according to the current natural environment; it should be noted that the control system can intelligently adjust the display brightness and display color of the wallpaper display screen, and the power corresponding to different display brightness and display color is different. 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.

[0026] Step S103: Obtain a second display brightness and a second display color based on the current human environment, the first display brightness, and the first display color.

[0027] Specifically, in this embodiment, the second display brightness is the display brightness obtained by adjusting the first display brightness according to the current human environment; the second display color is the display color obtained by adjusting the first display color according to the current human environment.

[0028] Step S104: Obtain a power supply voltage based on the second display brightness and the second display color.

[0029] Specifically, in this embodiment, obtaining the power supply voltage according to the second display brightness and the second display color includes the following steps: 1. Establish a mapping relationship: (1) Collect a large amount of experimental data covering different display brightnesses, 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.

[0030] 2. Color space conversion: 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.

[0031] 3. Brightness and color feature extraction: (1) Extract brightness (V) and saturation (S) from the converted HSV color space; (2) Integrate the second display brightness with the brightness (V) of the color to form a comprehensive brightness index.

[0032] 4. Query the mapping relationship: Based on the comprehensive brightness index and the saturation (S) of the color, look up the corresponding power supply voltage in the mapping table or function.

[0033] 5. Correction and adjustment: Consider factors such as the characteristics of the LED cabinet and the ambient temperature, and correct and adjust the found power supply voltage.

[0034] 6. Output the result: Finally, obtain the power supply voltage suitable for the current second display brightness and second display color.

[0035] The DC power supply method based on the LED cabinet provided in this embodiment first obtains the current natural environment and the current human environment corresponding to the LED cabinet at the current time node. According to the current natural environment, the first display brightness and the first display color adapted thereto are obtained. Then, the current human environment is combined with the first display brightness and the first display color, and the first display brightness and the first display color are adjusted 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. Finally, the power supply voltage is obtained 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 the user's satisfaction with the display brightness and the display color.

[0036] Referring to Figure 2 , in one implementation manner of this embodiment, step S103 of obtaining the second display brightness and the second display color based on the current human environment, the first display brightness and the first display color includes steps S201 to S207: Step S201: Obtain the personnel information in the target area.

[0037] Specifically, the target area is the area where the LED cabinet is located. If the LED cabinet is installed indoors, the target area can be the space in the room. If the LED cabinet is installed outdoors, the target area can be a spherical area with the LED cabinet as the center of the sphere and a radius of 5 meters. The personnel information is the relevant information of the personnel entering the target area, including personnel identity information, height, weight, appearance, age, physical condition, and preferences, etc. In this embodiment, an omnidirectional camera device is installed on the wallpaper display screen to photograph the personnel entering the target area.

[0038] Step S202: If no personnel information is detected, obtain the idle time of the personnel in the target area.

[0039] Specifically, in this embodiment, the personnel idle time is the average time length when there is no personnel entering the target area.

[0040] Step S203: Obtain the historical detection time of the personnel information.

[0041] Specifically, in this embodiment, the historical detection time is the time when it was last detected that there were personnel entering the target area.

[0042] Step S204: Based on the historical detection time, the current time node, and the personnel idle time, obtain the remaining idle time.

[0043] Specifically, the idle remaining time is the remaining time when no one enters the target area. In this embodiment, the idle remaining time = the personnel idle time - (the current time node - the historical detection time).

[0044] Step S205: If the idle remaining time is greater than or equal to the first time threshold, obtain the second display brightness and the second display color based on the standby mode.

[0045] Specifically, the first time threshold is a pre-set judgment criterion 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. Therefore, the wallpaper display screen can be adjusted to the standby mode to reduce the consumption of power resources. Among them, the standby mode is a low-power operation state when no main work tasks are performed.

[0046] Step S206: If the idle remaining time is less than or equal to the second time threshold, obtain the second display brightness and the second display color based on the first display brightness and the first display color.

[0047] Specifically, the second time threshold is a pre-set judgment criterion for determining whether the idle remaining time is too short. In this embodiment, the second time threshold can be 10 minutes or other time. It should be noted that the first time threshold is greater than the second time threshold; when the idle remaining time is less than or equal to the second time threshold, it means that someone will enter the target area soon. Therefore, there is no need to make other adjustments to the display brightness and display color of the wallpaper display screen, and directly use the first display brightness and the first display color as the second display brightness and the second display color.

[0048] Step S207: If the idle remaining time is greater than the second time threshold and less than the first time threshold, obtain the second display brightness and the second display color based on the low-brightness mode.

[0049] Specifically, in this embodiment, if the idle remaining 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 within a short period of time, but someone will enter after a slightly longer period of time. Therefore, the display brightness and display color can be appropriately adjusted to be in the low-brightness mode, which not only helps to reduce power consumption but also helps to prevent the frequent opening and closing of the wallpaper display screen, thus affecting the service life of the wallpaper display screen. Among them, 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. It is also possible to directly preset the display brightness and display color corresponding to the low-brightness mode. 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 preset for the low-brightness mode.

[0050] For the DC power supply method based on the LED box provided in this embodiment, if no personnel information is detected, it means that no one has entered the target area. Further obtain the personnel idle time and the historical detection time in the target area, so as to calculate the idle remaining time in the target area. Then, by judging the size relationship between the idle remaining time and the first time threshold and the second time threshold, the corresponding second display brightness and second display color can be obtained according to the actual situation, which helps to improve the user's satisfaction with the display brightness and display color.

[0051] Refer to Figure 3 , in one implementation manner of this embodiment, after step S201 of obtaining the personnel information in the target area, steps S301 to S308 are further included: Step S301: If personnel information is detected, determine whether there is specified personnel information in the personnel information.

[0052] Specifically, the specified personnel information is the personnel information corresponding to the specified personnel. In this embodiment, the personnel information of the specified personnel can be pre-entered into the relevant system in advance. When the personnel information is obtained, the personnel information is matched with the pre-entered personnel information. When the matching is successful, it means that there is specified personnel information in the personnel information.

[0053] Step S302: If there is specified personnel information, obtain the number of personnel based on the personnel information.

[0054] Specifically, the number of personnel is the number of people who have entered the target area.

[0055] Step S303: If the number of personnel is equal to 1, obtain the specified mode based on the specified personnel information.

[0056] Specifically, in this embodiment, if the number of people is equal to 1, it means that only one person enters the target area, and this person must be the designated person. Therefore, according to the designated person information of the designated person, the corresponding display mode is obtained, and this display mode is the designated mode. It should be noted that the designated mode is a display mode customized according to the designated person information, and the designated modes corresponding to different designated person information may also vary.

[0057] Step S304: Based on the first display brightness, the first display color, and the designated mode, obtain the second display brightness and the second display color.

[0058] Specifically, in this embodiment, according to the designated mode, the display brightness and display color suitable for the designated person can be known, and then combined with the first display brightness and the first display color, the final second display brightness and the second display color are generated.

[0059] Step S305: If the number of people is greater than 1, then determine whether the number of people is equal to the designated number.

[0060] 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. Further determine whether the number of people is equal to the designated number, so as to determine whether all the people entering the target area are designated people. Among them, the designated number is the number of designated people entering the target area.

[0061] Step S306: If the number of people is equal to the designated number, then based on the person information, obtain the priority display levels of different designated people.

[0062] Specifically, in this embodiment, if the number of people is equal to the designated number, it means that all the people entering the target area are designated people, and the settings can be made according to the priority display levels of the designated people. Therefore, further obtain the priority display levels of different designated people. Among them, the priority display level is the preferentially adapted display level. The higher the priority display level, the more preferentially the second display brightness and the second display color of the wallpaper display screen will be adapted to the person information of this designated person.

[0063] Step S307: Based on the priority display levels, obtain the highest display level.

[0064] Specifically, in this embodiment, the highest display level is the highest priority display level among the priority display levels of all designated people entering the target area.

[0065] Step S308: Based on the first display brightness, the first display color, and the highest display level, obtain the second display brightness and the second display color.

[0066] Specifically, in this embodiment, according to the highest display level, the display brightness and display color suitable for preferential adaptation of the specified personnel can be obtained. Then, in combination with the first display brightness and the first display color, the final second display brightness and second display color are generated.

[0067] The DC power supply method based on the LED box body provided by this embodiment determines whether there is specified personnel information in the personnel information. If so, it further obtains the number of personnel and determines whether the number of personnel is equal to 1. If it is equal to 1, a corresponding specified mode is generated according to the personnel information of the specified personnel, and then the final second display brightness and second display color are generated in combination with the specified mode, the first display brightness and the first display color; if it is greater than 1, it further determines whether the number of personnel is equal to the specified number. If they are equal, it further obtains the highest display level among different specified personnel, and then the final second display brightness and second display color are generated in combination with the highest display level, the first display brightness and the first display color; Selecting a more targeted method according to different situations to obtain the corresponding second display color and second display brightness helps the second display color and second display brightness to better meet the user requirements, thereby helping to improve the user's satisfaction with the display brightness and display color.

[0068] Refer to Figure 4 , in one implementation manner of this embodiment, step S308 obtains the second display brightness and second display color based on the first display brightness, the first display color, and the highest display level, including steps S401 to S404: Step S401: If the highest display level is the specified display level, obtain the second display brightness and second display color based on the first display brightness, the first display color, and the highest display level.

[0069] Specifically, in this embodiment, the specified display level is the pre-set display level. In this embodiment, the specified display level can be set to the top 1% priority display level among all specified personnel.

[0070] Step S402: If the highest display level is not the specified display level, obtain the level difference between the highest display level and the second highest display level.

[0071] Specifically, in this embodiment, the second highest display level is the second highest priority display level among the priority display levels of all specified personnel entering the target area, and the level difference is the difference obtained by subtracting the second highest display level from the highest display level.

[0072] Step S403: If the level difference exceeds the level difference threshold, obtain the second display brightness and second display color based on the first display brightness, the first display color, and the highest display level.

[0073] Specifically, in this embodiment, if the level difference exceeds the level difference threshold, it indicates that the level gap between the highest display level and the second highest display level is relatively large. Therefore, it is necessary to preferentially adapt the personnel information of the designated personnel 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. Herein, the level difference threshold is a judgment criterion for determining whether the level difference is too large.

[0074] Step S404: If the level difference does not exceed the level difference threshold, then based on the first display brightness and the first display color, obtain the second display brightness and the second display color.

[0075] Specifically, in this embodiment, if the level difference does not exceed the level difference threshold, it indicates that the level gap between the highest display level and the second highest display level is relatively small. Therefore, it is not possible to preferentially adapt the personnel information of the designated personnel corresponding to the highest display level, but rather to consider most or even all of the designated personnel. Therefore, the display is directly performed according to the first display brightness and the second display brightness.

[0076] For the DC power supply method based on the LED box provided in this embodiment, if the highest display level is the designated display level, then based on the first display brightness, the first display color, and the highest display level, obtain the second display brightness and the second display color; if the highest display level is not the designated display level, then obtain the level difference between the highest display level and the second highest display level, and determine whether the level difference exceeds the level difference threshold. If it exceeds, then based on the first display brightness, the first display color, and the highest display level, obtain the second display brightness and the second display color. If it does not exceed, then based on the first display brightness and the first display color, obtain the second display brightness and the second display color; first determine whether the highest display level is the designated display level, and then determine whether the level difference exceeds the level difference threshold. After double judgment, select the corresponding method to obtain the second display brightness and the second display color according to the judgment result, which helps the obtained second display brightness and second display color to better meet the user's needs.

[0077] Refer to Figure 5 , in one implementation manner of this embodiment, after step S305, if the number of personnel is greater than 1 and it is determined whether the number of personnel is equal to the designated number, steps S501 to S507 are further included: Step S501: If the number of personnel is not equal to the designated number, then obtain the standing positions and action characteristics of different personnel.

[0078] Specifically, if the number of personnel is not equal to the specified number, it means that there must be non-specified personnel among the personnel entering the target area. Further obtain the standing positions and action characteristics of different personnel. In this embodiment, the standing position distribution is the distribution of the positions of all personnel. Through this standing position distribution, the status or importance level of this part of the personnel can be roughly obtained. In this embodiment, generally, the closer the standing position is to the center, the higher the status of the personnel or the higher the importance level of this time; the action characteristic is the action made by each person.

[0079] Step S502: Based on the standing position distribution, obtain the personnel at the central standing position.

[0080] Specifically, in this embodiment, the personnel at the central standing position are the personnel standing at the most central position.

[0081] Step S503: Determine whether there are multiple personnel at the central standing position.

[0082] Step S504: If there are no multiple personnel at the central standing position, determine whether the personnel at the central standing position is a specified person.

[0083] Step S505: If the personnel at the central standing position is not a specified person, obtain the second display brightness and the second display color based on the first display brightness and the first display color.

[0084] Specifically, in this embodiment, if the personnel at the central standing position is not a specified person, it means that the personnel at the central standing position is an outsider, and it also means that this outsider is the person with the highest status or the most important person in this trip among this part of the personnel. In order to better meet their needs, the display brightness and display color cannot be adjusted according to the priority display level or the specified mode, etc. Therefore, directly use the first display brightness and the first display color as the second display brightness and the second display color.

[0085] Step S506: If the personnel at the central standing position is a specified person, determine whether the specified person is a guiding person based on the action characteristics.

[0086] Specifically, if the person in the central position is a designated person, it means that the person in the central position is the designated person. To determine whether this designated person is the person with the highest status or the most important person in this group during this trip, further judge whether he is a guiding person based on the action characteristics of the designated person. In this embodiment, a guiding person is a person who is engaged in guiding others or introducing others, etc. Therefore, he is not the person with the highest status or the most important person in this group, and the person he guides is the person with the highest status or the most important person in this group; it is possible to judge whether he is a guiding person according to guiding gestures or introducing gestures, etc. In this embodiment, machine learning language is pre - used to train a large amount of data, which helps to accurately distinguish whether the designated person is a guiding person according to the action characteristics of the designated person.

[0087] Step S507: If the designated person is a guiding person, obtain a second display brightness and a second display color based on the first display brightness and the first display color.

[0088] Specifically, in this embodiment, if the designated person is a guiding person, it means that the person with the highest status or the most important person in this group during this trip is still an outsider. Therefore, the method of obtaining the second display brightness and the second display color is the same as that in step S505.

[0089] The DC power supply method based on the LED box body provided by this embodiment obtains the standing position distribution and action characteristics of different people, and based on the standing position distribution, obtains the person in the central position according to the standing position distribution and action characteristics. Then, according to whether the person in the central position is a designated person, select the corresponding method to obtain the second display brightness and the second display color, which helps to improve the user's satisfaction with the display brightness and the display color.

[0090] Refer to Figure 6 , in one implementation manner of this embodiment, it further includes steps S601 to S605: Step S601: Obtain the living pattern of the designated person based on the personal information of the designated person.

[0091] Specifically, in this embodiment, the living pattern includes working hours, rest hours, entertainment hours, and preferences corresponding to work, entertainment, and rest, etc.

[0092] Step S602: Obtain the time range when the designated person is in the target area based on the living pattern.

[0093] Step S603: Judge whether other person information is detected within the time range.

[0094] Step S604: If no other person information is detected, obtain a designated mode based on the living pattern.

[0095] Step S605: Obtain the power supply voltage based on the specified mode.

[0096] For the DC power supply method based on the LED box provided in this embodiment, first obtain the living pattern of the specified person according to the personal information of the specified person, then obtain the time range of the specified person in the target area according to the living pattern. When no other person is detected within this time range, directly obtain the corresponding specified mode according to the living pattern of the specified person, and finally obtain the corresponding power supply voltage according to the specified mode; selecting the corresponding specified mode for power supply according to the living pattern of the specified person helps the display color and display brightness to better fit the living habits of the specified person, which not only helps reduce power consumption but also helps improve user satisfaction.

[0097] Refer to Figure 7 , in one implementation of this embodiment, after determining whether other person information is detected in step S603 within the time range, steps S701 to S705 are further included: Step S701: If other person information is detected, determine whether a mode adjustment instruction is detected.

[0098] Specifically, in this embodiment, the mode adjustment instruction is an instruction for intelligently adjusting the current mode according to the current actual situation, and this instruction can be sent through an instruction button, such as a remote control.

[0099] Step S702: If a mode adjustment instruction is detected, obtain the person characteristics.

[0100] Specifically, in this embodiment, the person characteristics include all characteristics corresponding to all persons.

[0101] Step S703: Obtain the current matching mode based on the person characteristics.

[0102] Specifically, the current matching mode is a display mode suitable for the current situation. For example, if the person characteristic is dancing gently, the current matching mode can be a soothing mode, and the soothing mode means a mode with relatively soft display brightness and display color.

[0103] Step S704: Obtain the matching color and matching brightness based on the current matching mode.

[0104] 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.

[0105] Step S705: Obtain the power supply voltage based on the matching color and matching brightness.

[0106] The DC power supply method based on the LED box provided by this embodiment, when a mode adjustment instruction is detected, it means that the wallpaper display screen will intelligently adjust the display brightness and display color according to the current environment for adaptation, further obtain the human characteristics, obtain the current matching mode according to the human characteristics, then obtain the corresponding matching color and matching brightness according to the current matching mode, and finally obtain the power supply voltage according to the matching color and matching brightness; after detecting the mode adjustment instruction, the system will select the corresponding mode for matching according to the human characteristics in the current situation, so that the color and brightness displayed on the wallpaper display screen are more adapted to the action characteristics, thus helping to improve user satisfaction.

[0107] Referring to Figure 8 , in one implementation manner of this embodiment, step S703 of obtaining the current matching mode based on the human characteristics includes steps S801 to S806: Step S801: Based on the human characteristics, obtain the human health characteristics, human action characteristics, and human status characteristics.

[0108] Specifically, in this embodiment, the human health characteristics are the human health conditions, including historical medical histories, etc.; the human action characteristics are all actions made by the person; the human status characteristics are the status of the person, such as stationary and moving, etc.

[0109] Step S802: Based on the human health characteristics, obtain the health mode options.

[0110] Specifically, in this embodiment, the health mode options are the display modes formulated according to the task health characteristics of all persons.

[0111] Step S803: Based on the human action characteristics, obtain the matching mode options.

[0112] Specifically, in this embodiment, the matching mode options are the display modes formulated according to the human action characteristics of all persons.

[0113] Step S804: Based on the human status characteristics, obtain the status mode options.

[0114] Specifically, in this embodiment, the status mode options are the display modes formulated according to the status characteristics of all persons.

[0115] Step S805: Based on the health mode options, matching mode options, and status mode options, obtain the target mode.

[0116] Specifically, in this embodiment, the target mode is the final display mode generated by comprehensively combining the health mode options, matching mode options, and status mode options.

[0117] Step S806: Based on the target mode, obtain the power supply voltage.

[0118] The DC power supply method based on the LED box body provided by this embodiment obtains the health characteristics, movement characteristics and status characteristics of a person according to the person's characteristics, and then combines the health mode option, matching mode option and status mode option. The generated final display mode helps the target mode to better meet the needs of more users, thereby improving the user satisfaction degree.
