Description
Technical Field
[0001] This application relates to the field of ground display device technology, and specifically to a station platform ground display device. Background Technology
[0002] Currently, white safety markings are typically affixed to the floor of train platforms, such as high-speed rail platforms. These markings are intended to warn passengers not to cross the lines to prevent safety risks. However, the existing white safety markings have a weak warning effect. Many passengers still frequently cross the safety markings while walking or waiting for their trains, making it difficult for the markings to effectively serve their warning purpose. In actual operation, platform staff still need to repeatedly remind passengers, increasing the cost of manual duty and resulting in poor safety control.
[0003] Meanwhile, station platforms typically use colored markers to indicate carriage numbers, while train information is displayed on screens above the platform. Passengers must check the ticket gates or the screens above the platform to confirm their current train number and the corresponding colored carriage marker before locating their carriage. Due to the variety of colors and complexity of the markers, many passengers cannot quickly and accurately locate their carriage while queuing. Some passengers also easily board the wrong train because they ignore the train information displayed on the screens above. The existing train and carriage information is not intuitive, clear, or convenient, directly leading to low passenger seating accuracy and boarding efficiency. Summary of the Invention
[0004] To address the aforementioned technical issues, this application provides a platform ground display device that can effectively improve the platform safety warning effect and passenger seat finding efficiency, reduce safety hazards and manual guidance costs, and improve boarding accuracy and platform operation order.

The light output component can display font and / or graphic information through the panel component to provide vehicle, warning, or guidance information.
[0006] As a preferred embodiment of the above solution, the platform ground display device further includes a control component disposed within the housing assembly.

[0007] As a preferred embodiment of the above solution, the platform ground display device also includes a microwave sensor disposed within the housing assembly. The microwave sensor is connected to a control unit. When the microwave sensor detects that someone is approaching its predetermined range, the control unit controls the LED light source to change its light emission, causing the panel assembly to display a color change as a warning.
[0008] As a preferred embodiment of the above solution, the platform ground display device also includes a sound-emitting structure disposed within the housing assembly. The sound-emitting structure is connected to a control unit.

[0011] As a preferred embodiment of the above scheme, the vehicle information includes carriage location information, the information layer contains different carriage location information, and the light output component can emit light at different positions and display different carriage location information through the panel component.
[0012] As a preferred embodiment of the above scheme, the information layer includes a warning sign pattern, and the light output component can emit light of a first color, a second color, or a third color. When the light output component emits light of the first color, the panel component displays a warning sign pattern of the first color to remind passengers not to cross; when the light output component emits light of the second color, the panel component displays a warning sign pattern of the second color to remind passengers that they can cross to get on and off the vehicle; when the light output component emits light of the third color, the panel component displays a warning sign pattern of the third color to remind passengers that crossing is prohibited.
[0013] As a preferred embodiment of the above scheme, the information layer contains guidance information, and the light output component can emit light and display the guidance information through the panel component to provide guidance information including exit and transfer information.
[0014] As a preferred embodiment of the above solution, the light output component includes an RGB light source, a dual-color light source, or a white monochromatic light source disposed within the housing assembly, as well as a light guide plate and a heat dissipation structure.

Detailed Implementation
[0019] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0020] It should be noted that when an element is described as "fixed to" another element, it can be directly on the other element, or one or more intermediate elements may exist between them. When an element is described as "connected to" another element, it can be directly connected to the other element, or one or more intermediate elements may exist between them. The terms "vertical," "horizontal," "left," "right," "upper," "lower," "inner," "outer," and "bottom," etc., used in this specification indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0021] As described in the background section, high-speed railway platform floors generally use adhesive white safety markings. These markings are mainly used to delineate safe waiting areas and warn waiting and passing passengers not to cross the line and approach the tracks to avoid safety accidents such as falls and crushing. However, due to factors such as ground material, passenger traffic, lighting conditions, and the limited variety of marking styles, the visual warning effect of existing white safety markings is weak, and their recognition and reminder functions are insufficient. Many passengers still unconsciously or deliberately cross the safety markings while walking, waiting, or queuing. The safety markings cannot truly play an effective warning and restraining role. During platform operation, staff still need to continuously patrol and repeatedly remind and dissuade passengers, which not only increases the cost of manual management but also makes it difficult to fundamentally eliminate the safety hazards caused by crossing the line.
[0022] Meanwhile, existing high-speed rail platform floor markings primarily use multi-colored stickers to guide passengers to their carriage numbers, while train information is mainly displayed on electronic screens above the platform. Passengers must first confirm their current train number through the ticket gate prompts or platform displays, then locate the corresponding colored carriage guide marker to determine their waiting position. In practice, the complex arrangement of multi-colored markers on the platform floor creates a hierarchical information structure, making it difficult for passengers, especially elderly passengers, first-time travelers, and those with luggage, to quickly identify their train number and carriage. This often results in passengers going to the wrong carriage or queuing incorrectly. Some passengers also easily board the wrong train or board the wrong train because they do not pay attention to the information on the overhead displays. In summary, the existing platform safety warnings and train / carriage guidance methods suffer from poor warning effectiveness, unintuitive information presentation, unclear guidance logic, and insufficient ease of use. These shortcomings affect platform operation order and traffic efficiency, and also reduce passenger seating accuracy and overall travel experience.
[0023] The platform ground display device proposed in this application optimizes and improves the platform safety warning structure and train number and carriage guidance method, which can significantly enhance the visual warning effect and restraining effect of ground safety markings, greatly reduce passengers' unintentional crossing of lines, reduce platform safety risks and the workload of manual guidance; at the same time, it can realize integrated and intuitive ground guidance of train number information and carriage location, so that passengers can quickly and accurately match the corresponding carriage waiting position without frequently looking up at the display screen, effectively avoiding problems such as looking for the wrong carriage or boarding the wrong train, and significantly improving the accuracy of passenger seating, the efficiency of entering the station and waiting for trains, and the overall operation and management level of the platform.
[0024] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0025] This application provides a station platform ground display device, such as... Figure 1As shown, it includes a housing assembly 1, a light output assembly 2, and a panel assembly 3. The housing assembly 1 is embedded in a ground groove, the light output assembly 2 is disposed inside the housing assembly 1 and is used for emitting light or displaying, and the panel assembly 3 is disposed at the upper end of the housing assembly 1 and is flush with the ground.
[0026] like Figure 1 , Figure 3 As shown, the housing assembly 1 may include a housing 11 and a waterproof connector 12. The housing 11 may be a rectangular strip and is embedded in a ground recess to protect the components inside. The waterproof connector 12 serves as an electrical connection port, connecting to the side wall of the housing 11 and connecting to the optical output assembly 2 inside the housing 11 to supply power to the optical output assembly 2.
[0027] like Figure 1 As shown, the platform ground display device also includes a control component 4 disposed within the housing assembly 1. The control component 4 is connected to the light output assembly 2. The control component 4 can be a controller such as a main control board. The control component 4 is disposed on the inner wall of the housing 11 and can communicate with the station's dispatch center to control the light output assembly 2 to emit light or display light. The light output assembly 2 includes an LED light source 21 or an LED dot matrix (not shown). The LED light source 21 emits light using light-emitting diodes. The LED dot matrix is an LED display module with a specific structure, consisting of multiple LEDs (usually monochrome, dual-color, or RGB) arranged in a matrix grid and connected by circuitry.
[0028] In one embodiment, the light output component 2 is an LED light source 21, and the controller 4 controls the LED light source 21 to emit light of different colors, so that the panel component 3 displays different colors to provide information on whether it is permissible to cross. At this time, the platform floor display device can be a safety marking within a certain range from the edge of the platform, which is a boundary line to ensure the personal safety of passengers. Under normal circumstances, it can be displayed as a white safety marking. The panel component 3 includes a transparent panel 31, which includes double-layer glass or polycarbonate sheet and has a certain thickness, such as 10 mm. The double-layer glass can be double-layer laminated tempered glass, and the polycarbonate sheet has high light transmittance and impact resistance, which improves the hardness and anti-crushing performance of the entire platform floor display device. The transparent panel 31 can be sealed with the upper end of the outer shell 11 by using a fluid filling adhesive sealing structure.
[0029] The light output component 2 can emit light of a first, second, third, or fourth color, which can be yellow, green, red, and white, respectively. When the light output component 2 emits the first color light, the panel component 3 displays the first color light to remind passengers not to cross; when the light output component 2 emits the second color light, the panel component 3 displays the second color light to remind passengers that they can cross to board or alight; when the light output component 2 emits the third color light, the panel component 3 displays the third color light to remind passengers not to cross, generally when passengers have already crossed or are about to cross. It is worth noting that, under normal circumstances, the panel component 3 is white; when the weather is dark or the platform lighting is insufficient, the light output component 2 can emit the fourth color light to supplement the illumination, making the panel component 3 display a bright white light; at night, the control component 4 can automatically control the light output component 2 to emit the fourth color light for supplemental illumination according to time periods, making the panel component 3 display a bright white light; after passengers enter the station, the light output component 2 emits the first color light to remind passengers not to cross.
[0030] In another embodiment, the light output component 2 is an LED light source 21, which can be an RGB light source board. The controller 4 controls the LED light source 21 to change its light emission when a person approaches, touches, or passes by the panel component 3, causing the panel component 3 to display a color change as a warning. In this case, the ground display device can be a warning sign line within a certain range from the edge of the platform. The panel component 3 includes a transparent panel 31 and an information layer 32. The transparent panel 31 includes double-layer glass or a polycarbonate sheet. The information layer 32 is a text and / or pattern information layer printed, coated, or pasted on the bottom surface of the transparent panel 31. The information layer 32 contains a warning sign pattern 321.
[0031] For example, the light output component 2 can emit light of a first color, a second color, or a third color, where the first color, second color, and third color can be yellow, green, and red, respectively. Figure 4 As shown, when the light output component 2 emits light of the first color, the panel component 3 displays a warning sign pattern 321 of the first color to remind passengers not to cross; when the light output component 2 emits light of the second color, the panel component 3 displays a warning sign pattern 321 of the second color to remind passengers that they can cross to get on and off the vehicle; when the light output component 2 emits light of the third color, the panel component 3 displays a warning sign pattern 321 of the third color to remind passengers that crossing is prohibited.
[0032] For example, the light output component 2 can emit light of a first color, a second color, or a third color, where the first color, second color, and third color can be yellow, blue, and red, respectively. Under normal circumstances, the light output component 2 emits light of the first color, and the panel component 3 displays a warning sign pattern 321 of the first color to remind passengers not to cross or approach the platform edge; when a passenger approaches or crosses the ground display device, the controller 4 controls the light output component 2 to emit a flashing light of the second and third colors, warning the passenger not to approach or cross the platform edge.
[0033] like Figure 2 As shown, the platform ground display device also includes a microwave sensor 5 housed within the housing assembly 1. The microwave sensor 5 is connected to a control unit 4. When the microwave sensor 5 detects someone approaching its predetermined range, the control unit 4 controls the LED light source 21 to change its light emission, causing the panel assembly 3 to display a color change as a warning. The microwave sensor 5 can be a millimeter-wave radar or a lidar. The millimeter-wave radar can be a short-range, high-resolution active directional millimeter-wave radar. Using human breathing algorithm technology, it can detect whether there are moving or stationary passengers within a certain range (e.g., 0.5-1 meter) between the ground display device, which serves as the original warning line, and the track, without sensing passengers on the other side of the warning line, thus realizing the function of an intelligent electronic fence. The microwave sensor 5 is located on the inner wall of the housing 11. Multiple sensors can be installed at different positions within the housing 11 as needed, forming a certain tilt angle with the inner wall of the housing 11 to ensure that the vertical sensing angle is 35-60° and the horizontal sensing angle is above 60-120°, facilitating the detection of personnel.
[0034] like Figure 2 As shown, the platform floor display device also includes a sound-generating structure 6 disposed within the housing assembly 1. The sound-generating structure 6 is connected to the control unit 4. When the microwave sensor 5 detects someone approaching its predetermined range, the control unit 4 controls the sound-generating structure 6 to emit a sound as a warning. The sound-generating structure 6 can be a vibration generator disposed below the panel assembly 3 within the housing 11. When the microwave sensor 5 detects someone approaching its predetermined range, the control unit 4 controls the vibration generator to vibrate, and the vibration conduction causes the surface of the panel assembly 3 to emit sound, so that the sound wave direction is directly facing the passenger, thereby playing warning language information. The warning language information can be a high-quality audio source that has been pre-recorded and stored in the storage of the control unit 4 within the housing 11.
[0035] When the microwave sensor 5 detects someone approaching its predetermined range, the controller 4 controls the light output component 2 to emit a flashing light of alternating second and third colors, or to output a single color light that flashes continuously, such as red, to warn passengers not to approach or cross the edge of the platform. At the same time, the sound-emitting structure 6 emits a sound to further enhance the warning effect.
[0036] In another embodiment, the light output component 2 is an LED light source 21, which can be a dual-color light strip, specifically a red-green light source. The control component 4 controls the LED light source 21 to display font and / or graphic information 22 via the panel component 3, providing vehicle, warning, or guidance information. When the LED light source 21 is not emitting light, the platform floor display device can be in the form of white safety markings. Vehicle information includes carriage location information, which may include numbers, arrows, etc. Figure 1 , Figure 5 As shown, panel assembly 3 includes a transparent panel 31 and an information layer 32. LED light source 21 can be disposed on one side of the bottom of the transparent panel 31. The information layer 32 is a layer of printed, coated, or pasted fonts and / or patterns on the bottom surface of the transparent panel 31. The information layer 32 contains information 322 about the positions of different carriages. Light output component 2 can emit light at different positions and display the information 322 about the positions of different carriages through panel assembly 3. Figure 6 , Figure 7 As shown, the information layer 32 contains guidance information 323. The light output component 2 can emit light and display the guidance information 323 through the panel component 3 to provide guidance information 323 including exit direction signs with text, letters, and arrow lights, convenient transfer signs, etc.
[0037] In another implementation, such as Figure 8 As shown, the light output component 2 is an LED dot matrix, and the control component 4 controls the LED dot matrix to display text and / or pattern information 22, which is then displayed through the panel component 3. At this time, the ground display device functions as a ground electronic display screen, used to display vehicle, warning, or guidance information, etc. The panel component 3 includes a transparent panel 31, which comprises double-layered glass or a polycarbonate sheet. The double-layered glass can be double-layered laminated tempered glass, and the polycarbonate sheet has high light transmittance and impact resistance, improving the overall hardness and anti-crushing performance of the platform ground display device. Vehicle information includes carriage location information 322, train number information, and time information, etc. Warning information includes safety warnings such as "Caution: Slippery" and guidance information 323 includes exit direction signs with text, letters, arrows, etc., and convenient transfer signs, etc. The control component 4 can communicate with the station's dispatch center to control the display content of the LED dot matrix.
[0038] For example, such as Figure 1As shown, the light output component 2 also includes a light guide plate 23 and a heat dissipation structure 24. The light guide plate 23 guides the light emitted by the RGB light source, dual-color light source, or white monochromatic light source. The light guide plate 23 can be disposed below the transparent panel 31 inside the housing 11. The heat dissipation structure 24 provides heat dissipation for the LED light source 21 or LED dot matrix, such as the RGB light source, dual-color light source, or white monochromatic light source. The heat dissipation structure 24 can be a heat sink. The heat dissipation structure 24 can be disposed below the transparent panel 31 and the light guide plate 23 inside the housing 11, and conducts heat in contact with the LED light source 21.
[0039] The platform ground display device of this application can be installed on the ground of large railway stations, mainly for high-speed railway platforms. A large railway station may have dozens of platform surfaces, and each platform surface may have dozens of platform ground display devices installed. Each platform ground display device is equivalent to a single device, and each device requires an independent IP address. High-speed serial communication is used between devices to solve the problems of multi-communication networking and cabling.
[0040] This application comprises a housing assembly 1, a light output assembly 2, and a panel assembly 3. The housing assembly 1 is embedded in a ground recess. The light output assembly 2 is disposed within the housing assembly 1 and is used for emitting light or displaying information. The light output assembly 2 can emit light of different colors, causing the panel assembly 3 to display different colors to provide information on whether passage is permitted. In this case, the light output assembly 2 is used for emitting light, and the panel assembly 3 serves as a warning light screen and also as a boundary line to ensure passenger safety on the platform. The light output assembly 2 can change its light emission when a person approaches, touches, or passes over the panel assembly 3, causing the panel assembly 3 to display a color change as a warning. In this case, the light output assembly 2 is used for emitting light, and the panel assembly 3 serves as a warning. 3. As a warning display screen, it uses color changes to warn passengers of crossing the boundary and remind them to stay away from safety markings. The light output component 2 can display font and / or graphic information 22 through the panel component 3 to provide vehicle, warning or guidance information. At this time, the light output component 2 can be used to emit light and display vehicle, warning or guidance information with the help of the font and / or graphic information layer on the panel component 3. The light output component 2 can also be used to display and directly display vehicle, warning or guidance information through the panel component 3 to help improve the efficiency of passengers finding seats and boarding, improve the accuracy of boarding, reduce safety hazards, reduce manual guidance costs, and improve the operational order of the platform.
