[0011] 3. The display screen cannot adjust its brightness or provide warnings when pedestrians approach, resulting in insufficient safety.

[0012] Technical solution

[0013] To achieve the above objectives, the present invention provides the following technical solution: a novel high-efficiency and energy-saving intelligent display screen, comprising a display screen body and a controller body. A buzzer is connected to the top surface of the display screen body, a driving component and the controller body are connected to the back of the display screen body, and a detection component is connected to the side of the controller body. The controller body includes a display module and a protection module. Both the controller body and the driving component are electrically connected to the display screen body. The display screen body comprises multiple sub-display screens spliced ​​together, wherein:

[0014] The driving component includes an input terminal and an output terminal connected to each sub-display screen of the main display screen body, and is used to control the image display of the sub-display screens;

[0015] The detection component includes an excitation signal source module and an image signal acquisition module, which are used to detect the fault source of the display screen body. When the display screen body is faulty, the input terminal is connected. By checking whether the display screen body is displaying normally, it is determined whether the fault is in the driving component or the display screen body. If the display screen body is displaying normally, the driving component is faulty; otherwise, the display screen body is faulty.

[0016] The controller body, through the display module and protection module in conjunction with the drive component, receives and integrates data on image display, brightness range, brightness level, and visual recognition of the display screen body, and controls the normal operation of each component and module;

[0017] The display module is connected to each sub-display screen, controls the opening and closing and brightness of the sub-display screens, receives signals transmitted by the protection module, controls the brightness of the sub-display screens to dim when a person gets close, and provides an early warning through a buzzer. It also controls the number of sub-display screens to be adjusted to correspond to the crowd density and range detected by the protection module.

[0018] The protection module includes an identification probe, a human detection unit, a radar detection unit, an infrared detection unit, and an early warning unit. The identification probe scans the environment around the display screen and the human detection unit identifies pedestrians. When someone approaches the surface of the display screen, the display module controls the brightness of the sub-display screen in the area corresponding to the person's approach to dim, and the early warning unit, in conjunction with an external buzzer, provides an audible warning. The radar detection unit and the infrared detection unit detect the dynamic density of the crowd within a circumferential radius of the display screen's location and, based on the detected density and the crowd's structure, drive the display module to shrink or expand the display area of ​​the main display screen.

[0019] Preferably, the controller body uses an FPGA chip as the core processor, and the processor contains multiple communication chips, including a switch button, a power module, a spectrum sensor, a temperature sensor, and a USB interface.

[0020] Preferably, the input end of the driving component is responsible for decoding the HDMI signal from the main body of the receiving controller, performing grayscale level expansion processing, and then sending it to the output end via the Ethernet port. The output end is responsible for receiving real-time image data and driving the entire display screen to display.

[0021] Preferably, the excitation signal source module of the detection component is mainly used to narrow down the fault range of the display screen body device. The excitation signal source module can be directly used as the input end of the display screen body under test. When the signal source is directly set as the input end of the display screen body under test, it will automatically generate corresponding video signals. These signals will be safely and reliably transmitted to the display screen body under test for image display detection.

[0022] Preferably, the image signal acquisition module of the detection component is mainly used to acquire VGA signals, PAL signals, and TTL signals. Through the signal processing driver board of the comprehensive detection driver component, the corresponding image signals are obtained and the signals are displayed completely. The image signal acquisition module is directly set as the output terminal of the main body of the display screen under test, and then the video signals generated by the display device under test are comprehensively acquired and the final acquisition results are displayed completely on the main body of the display screen.

[0023] Preferably, the distance relationship between the person and the main body of the display screen in the identification probe and human detection unit of the protection module is expressed by the following formula:

[0024] in:

[0025]

[0026] d is the distance between the person and the main body of the display screen, in meters;

[0027] D thThis is the threshold distance, in meters (m). It means that when the distance between a person and the main body of the display screen is less than or equal to this value, the brightness of the main body of the display screen will begin to decrease.

[0028] L env The brightness of the display screen is obtained from environmental monitoring, and the unit is any brightness unit.

[0029] L(d) represents the brightness of the display screen at a distance d.

[0030] L min This is the minimum brightness of the main body of the display screen, that is, the lowest brightness of the main body of the display screen when a person is very close to the main body of the display screen;

[0031] When the distance d between the person and the main body of the display screen is greater than the threshold distance D th At that time, the main brightness L(d) of the display screen remains the same as the environmental monitoring brightness L. env ;

[0032] When the distance d between the person and the main body of the display screen is less than or equal to the threshold distance D th When the brightness of the main display screen L(d) decreases gradually according to the inverse square law of distance, it will not fall below the set minimum brightness L. min ;

[0033] The constant α is used to control the rate at which brightness decreases.

[0034] Preferably, the formula for calculating the relationship between the main display area of ​​the display screen and the crowd density range in the protection module is as follows;

[0035]

[0036] in:

[0037] D base The basic display area of ​​the main body of the display screen, in meters (m). 2 ;

[0038] D max The maximum display area of ​​the main body of the display screen (1), in meters. 2 , such that when ρ2≥ρ1, D base The maximum value of +k·(ρ2-ρ1) is no more than D. max The value;

[0039] ρ1 represents the base population density at which the display range is adjusted, in units of people / m². 2 ;

[0040] ρ2 represents the current population density, in people / m². 2

[0041] k represents the increase in the display area in square meters for each additional unit of population density, expressed in meters (m). 2

[0042] A represents the main display area of ​​the screen, measured in meters (m). 2 .

[0043] Beneficial effects

[0044] This invention provides a novel high-efficiency and energy-saving intelligent display screen. It has the following beneficial effects:

[0045] 1. This invention employs a design where the main display screen is spliced ​​together with multiple sub-display screens, enabling flexible adjustment of the display area. When full-screen display is not required, the controller can intelligently control the shutdown of some sub-display screens through the display module, thereby effectively reducing energy consumption and achieving high efficiency and energy saving. The radar detection unit and infrared detection unit in the protection module can monitor the dynamic density of the crowd around the main display screen in real time. Based on the crowd density and range structure, the display area size of the main display screen is intelligently adjusted. This intelligent control not only improves the user experience but also further reduces unnecessary energy consumption.

[0046] 2. This invention uses a detection component connected to the driving component on the back of the display screen to perform fault detection. The introduction of the detection component enables the display screen to quickly locate the problem when a fault occurs. Through the excitation signal source module and the image signal acquisition module, it can be determined whether the fault originates from the driving component or the display screen itself, thereby greatly shortening the time for fault diagnosis and repair.

[0047] 3. This invention employs a combination of a display module and a protection module, enabling the main display screen to automatically adjust the brightness of corresponding areas based on the approach of pedestrians and provide audible warnings via a buzzer. This user-friendly design not only enhances user comfort but also effectively prevents accidental injuries caused by pedestrians accidentally touching the main display screen. The recognition probe and human detection unit in the protection module can scan the environment where the main display screen is located in real time, ensuring that the main display screen can still operate normally in complex environments, providing users with a higher level of safety.

[0054] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Specific Implementation Example 1:

[0056] like Figures 1-5 As shown, a novel high-efficiency and energy-saving intelligent display screen includes a display screen body 1 and a controller body 5. A buzzer 2 is connected to the top surface of the display screen body 1, and a drive component 3 and the controller body 5 are connected to the back of the display screen body 1. A detection component 4 is connected to the side of the controller body 5. The controller body 5 includes a display module and a protection module. The controller body 5 and the drive component 3 are both electrically connected to the display screen body 1. The display screen body 1 is formed by splicing multiple sub-display screens. The entire device uses the buzzer 2 to provide early warning for the display screen body 1. The buzzer 2 is connected to the detection component 4 and is used to provide early warning after detecting a fault in the display screen body 1. The buzzer 2 is also electrically connected to the protection module and is used to provide early warning during the identification process of the protection module, such as when a pedestrian approaches or the distance is too close.

[0057] in:

[0058] The driving component 3, including an input terminal and an output terminal, is connected to each sub-display screen of the display body 1 and is used to control the image display of the sub-display screen;

[0059] The detection component 4 includes an excitation signal source module and an image signal acquisition module, which are used to detect the fault source of the display body 1. When the display body 1 is faulty, the input terminal is connected. By checking whether the display body 1 displays normally, it is determined whether the fault is the drive component 3 or the display body 1. If the display body 1 displays normally, the drive component 3 is faulty; otherwise, the display body 1 is faulty.

[0060] The controller body 5, in conjunction with the display module and the protection module and the drive component 3, receives and integrates the data on image display, brightness range, brightness level and visual recognition of the display screen body 1, and controls the normal operation of each component and module;

[0061] The display module connects to each sub-display screen, controls the opening and closing and brightness of the sub-display screens, receives signals transmitted by the protection module, controls the brightness of the sub-display screens to dim when people get close, and provides an early warning through buzzer 2. It also controls the number of sub-display screens to be displayed in accordance with the crowd density and range detected by the protection module.

[0062] The protection module includes an identification probe, a human detection unit, a radar detection unit, an infrared detection unit, and an early warning unit. The identification probe scans the environment of the location of the main display screen 1, and the human detection unit identifies pedestrians. When someone approaches the surface of the main display screen 1, the display module controls the brightness of the sub-display screen in the area corresponding to the person's approach location to dim, and the early warning unit works with an external buzzer 2 to issue an audible warning. The radar detection unit and infrared detection unit detect the dynamic density of the crowd within the circumferential radius of the location of the main display screen 1, and drive the display module to shrink or expand the display area of ​​the main display screen 1 based on the detected density and the structure of the crowd range. Specific Implementation Example 2:

[0064] like Figures 1-5 As shown, based on the content of Specific Embodiment 1, the following is further disclosed: The controller body 5 uses an FPGA chip as its core processor, and the processor contains multiple communication chips, including a switch button, a power module, a spectrum sensor, a temperature sensor, and a USB interface. With the FPGA chip as the core processor, the input terminal of the drive component 3 is responsible for decoding the HDMI signal received from the controller body 5, performing grayscale level expansion processing, and then sending it to the output terminal via the Ethernet port. The output terminal is responsible for receiving real-time image data and driving the entire display screen body 1 to display the image.

[0065] Image display control: When an image needs to be displayed, the display module of the controller body 5 generates a corresponding control signal based on the image data and sends the signal to each sub-display screen through the drive component 3;

[0066] The driving component 3 drives the corresponding sub-display screen to display images, including parameters such as brightness and color, according to the received control signals.

[0067] Intelligent control: The protection module uses identification probes and human detection units to scan the environment around the main body of the display screen 1 in real time to identify the location and movement of pedestrians;

[0068] When someone approaches the main body of the display screen 1, the protection module sends a signal to the display module. The display module controls the brightness of the sub-display screen in the corresponding area to dim through the drive component 3, so as to reduce interference with pedestrians and the risk of accidental touch. At the same time, the warning unit triggers the buzzer 2 to give an audible warning to remind pedestrians to pay attention.

[0069] Crowd dynamic density detection and display area adjustment: The radar detection unit and the infrared detection unit detect the dynamic density of the crowd within the circumferential radius of the location of the main body of the display screen 1.

[0070] Based on the detected density data, the controller body 5 intelligently adjusts the display area size of the display screen body 1 through the display module and drive component 3. When the crowd density is high, the display area is expanded to accommodate more information; when the crowd density is low, the display area is reduced to save energy. By using a splicing design of multiple sub-display screens, the display screen body 1 achieves flexible display area adjustment. When full-screen display is not required, the controller body 5 can intelligently control the shutdown of some sub-display screens through the display module, thereby effectively reducing energy consumption and achieving high efficiency and energy saving. The radar detection unit and infrared detection unit in the protection module can monitor the dynamic density of the crowd around the display screen body 1 in real time. Based on the crowd density and range structure, the display area size of the display screen body 1 is intelligently adjusted. This intelligent control not only improves the user experience but also further reduces unnecessary energy consumption. Specific Implementation Example 3:

[0072] like Figures 1-5 As shown, based on the content of specific embodiments one and two, the following is further disclosed:

[0073] When performing image display control between the display screen body 1 and the controller body 5, at least the following disclosed technologies are employed:

[0074] LED backlight technology: The main body 1 of the energy-saving LED display adopts LED backlight technology. By adjusting the brightness and color of the LEDs, a higher energy-saving effect can be achieved. This technology can also be applied to the main body 1 of the new high-efficiency energy-saving smart display to improve energy efficiency and reduce energy consumption.

[0075] Dynamic dimming technology: The energy-saving LED display body 1 adopts dynamic dimming technology, which automatically adjusts the brightness level of the LED according to the brightness requirements of the displayed content. The new high-efficiency energy-saving intelligent display body 1 can further combine this technology to intelligently adjust the brightness of the display body 1 according to factors such as crowd density and ambient brightness.

[0076] Color control technology: By precisely controlling the brightness and color mixing ratio of LEDs, the LED display body 1 can achieve high-quality color control. The new high-efficiency energy-saving intelligent display body 1 can inherit this technology to ensure that the accuracy and vividness of image colors are maintained when adjusting the display area and brightness. Specific Implementation Example 4:

[0078] like Figures 1-5 As shown, based on the content of specific embodiments one and two, the following is further disclosed:

[0079] like Figure 3 As shown, the excitation signal source module of the detection component 4 is mainly used to narrow down the fault range of the display screen body 1. Under this module, the excitation environment data of the display screen body 1 under test can be processed in a standardized manner, providing an important basis and reference for controlling the display screen body 1 during large-scale deployment in the later stage. Finally, the fault location is narrowed down to the smallest unit. After testing, the display screen body 1 under test all have black screen problems. The root cause is that the display screen body 1 itself has abnormal problems or the driving module is abnormal. The excitation signal source module can be directly used as the input end of the display screen body 1 under test. When the signal source is directly set as the input end of the display screen body 1 under test, it will automatically generate the corresponding video signal. These signals will be safely and reliably transmitted to the display screen body 1 under test for image display detection.

[0080] like Figure 4 As shown, the image signal acquisition module of the detection component 4 is mainly used to acquire VGA signals, PAL signals, and TTL signals. It obtains the corresponding image signals through the signal processing driver board of the comprehensive detection driver component 3 and displays the signals completely. The image signal acquisition module is directly set as the output terminal of the main body 1 of the display screen under test, and then comprehensively acquires the video signals generated by the display device under test, and displays the final acquisition results completely on the main body 1 of the display screen. The detection component 4 is connected to the driver component 3 on the back of the main body 1 for fault detection. The introduction of the detection component 4 enables the main body 1 of the display screen to quickly locate the problem when a fault occurs. Through the excitation signal source module and the image signal acquisition module, it can be determined whether the fault originates from the driver component 3 or the main body 1 of the display screen itself, thereby greatly shortening the time for fault diagnosis and repair. Specific Implementation Example 5:

[0082] like Figures 1-5 As shown, based on the content of specific embodiments one and two, the following is further disclosed:

[0083] The formula relating the distance between a person and the display screen 1 is divided into two parts. One part is that when the distance between the person and the display screen 1 exceeds a certain threshold, the brightness of the display screen 1 adjusts according to its own environmental monitoring. The other part is that when the distance between the person and the display screen 1 is shortened to within the threshold, the brightness of the display screen 1 at the person's position decreases.

[0084] The parameters are set as follows:

[0085] d is the distance between a person and the main body of the display screen 1, in meters;

[0086] D thThis is the threshold distance, in meters. It means that when the distance between a person and the main body of the display screen 1 is less than or equal to this value, the brightness of the main body of the display screen 1 will begin to decrease.

[0087] L env The brightness of the main body of the display screen 1 is obtained from environmental monitoring, and the unit is any brightness unit;

[0088] L(d) represents the brightness of the display screen 1 at a distance d, in any unit of brightness.

[0089] L min This represents the minimum brightness of the main body 1 of the display screen, in any unit of brightness. It is the lowest brightness value of the main body 1 of the display screen when a person is very close to it.

[0090] When d>D th At that time, the brightness of the main display screen 1 adjusts according to its own ambient light, i.e., L(d) = L env ;

[0091] When D th When the brightness of the main body 1 of the display screen corresponding to the person's position decreases, and the brightness decrease is set to be inversely proportional to the square of the distance, we get:

[0092]

[0093] in:

[0094] The constant α is used to control the rate of brightness reduction; this formula ensures that when d = D... th At that time, L(d)=L env Furthermore, as d decreases, L(d) will gradually decrease, but will not be less than L. min ;

[0095] Therefore, L(d) is restricted to be no less than L. min The following formula is obtained:

[0096]

[0097] Integrating the two formulas above, we obtain the distance relationship between the identification probe in the protection module and the human detection unit and the main body of the display screen 1. The formula is as follows:

[0098] in:

[0099]

[0100] When the distance d between the person and the main body of the display screen 1 is greater than the threshold distance D th At that time, the brightness L(d) of the main display screen 1 remains the same as the environmental monitoring brightness L. env ;

[0101] When the distance d between the person and the main body of the display screen 1 is less than or equal to the threshold distance D th At this time, the brightness L(d) of the main body of the display screen 1 will gradually decrease according to the inverse square relationship of the distance, but will not fall below the set minimum brightness L. min .

[0102] Based on the above formula, a practical experimental simulation was conducted, where the following settings were made:

[0103] Threshold distance D th =1m;

[0104] Environmental monitoring brightness L env =100;

[0105] Minimum brightness L min =20;

[0106] The rate constant for brightness reduction is α = 10.

[0107] The data is shown in Table 1 below:

[0108]

[0109]

[0110] Table 1

[0111] As can be seen from the above formula and the data in Table 1, when the distance between a person and the main body of the display screen 1 is less than the set threshold, the main body of the display screen 1 can automatically adjust its brightness using the above formula. By adapting the main body of the display screen 1 to the protection module, the main body of the display screen 1 can automatically adjust the brightness of the corresponding area according to the approach of the pedestrian, and issue an audible warning through the buzzer 2. This humanized design not only improves the user's comfort, but also effectively avoids accidental injury caused by pedestrians accidentally touching the main body of the display screen 1. Specific Implementation Example Six:

[0113] like Figures 1-5 As shown, based on the content of specific embodiments one and two, the following is further disclosed:

[0114] The formula for calculating the relationship between the display range of the main display screen 1 in the protection module and the crowd density range is as follows;

[0115]

[0116] in:

[0117] D base The basic display area of ​​the main body of the display screen 1, in meters. 2 ;

[0118] D maxThe maximum display area of ​​the main body of the display screen (1), in meters. 2 , such that when ρ2≥ρ1, D base The maximum value of +k·(ρ2-ρ1) is no more than D. max The value;

[0119] ρ1 represents the base population density at which the display range is adjusted, in units of people / m². 2 ;

[0120] ρ2 represents the current population density, in people / m². 2

[0121] k represents the increase in the display area in square meters for each additional unit of population density, expressed in meters (m). 2 ;

[0122] A represents the display area of ​​the main body of the display screen 1, in meters (m). 2 .

[0123] Based on the above formula, a detailed description of the surface of the display body 1 is provided, assuming the following parameters:

[0124] The maximum display area of ​​the main body of the display screen 1 is D max =120m 2 ;

[0125] The basic display area of ​​the main body of the display screen 1 is D. base =100m 2

[0126] The display screen body 1 begins adjusting the basic population density ρ1 of the display area to 5 people / m². 2 ;

[0127] For each additional unit of population density, the display area increases by square meters, k = 2m 2

[0128] When the population density is ρ2 = 3 people / m 2 When the value is below ρ1, the display range remains the basic display range, i.e., A = D. base =100m 2 The main body of the display screen 1 ensures a display range of 100m. 2 constant;

[0129] When the population density is ρ2 = 8 people / m 2 When the value is higher than ρ1, the display range begins to adjust. According to the formula, A = D. base +k·(ρ2-ρ1)=100+2(8-5)=106m 2 The display screen body 1 adjusts the display range to 106m. 2 ;

[0130] When the population density is ρ2 = 16 people / m 2 When the value is higher than ρ1, the display range begins to adjust. According to the formula, A = D. base +k·(ρ2-ρ1)=100+2(16-5)=122m 2 Since the maximum display area of ​​the main body of the display screen 1 is D max =120m 2 Therefore, the maximum display range of the main display unit 1 is 120m at this time. 2 ;

[0131] In actual use, the ratio of the basic display range to the maximum display range of the main body of the display screen 1 is selected according to the actual use. Generally, the basic display range is selected to be between 60% and 80% of the maximum display range. The specific selection and setting depends on the actual usage needs of the main body of the display screen 1. Specific Implementation Example 7:

[0134] The identification probe, human detection unit, radar detection unit, and infrared detection unit in the protection module all adopt publicly available technical structures. While achieving the aforementioned functions, their working principles and technical content must at least include the following:

The camera converts the captured images into electrical signals and transmits them to the internal processing unit. The processing unit uses a pre-set algorithm to analyze the images, thereby identifying objects, scenes or other feature information in the images.
