Description

Technical Field

[0001] This utility model relates to the field of urban rail transit facilities technology, specifically to a subway platform safety door system, and more particularly to an intelligent platform door device that integrates multimedia information display and human-computer interaction functions. Background Technology

[0002] Subway platform screen doors (or platform gates) are key equipment in modern subway systems to ensure passenger safety and improve operational efficiency. Traditional platform screen doors have a single function, mainly serving to isolate the tracks from the platform and provide safety protection. Their doors are usually made of ordinary or tempered glass, which only has the functions of light transmission and isolation.

[0003] Currently, information in subway stations (such as train timetables, route maps, announcements, and commercial advertisements) is mainly disseminated through fixed display screens or advertising light boxes suspended from the ceilings of station halls and platforms. This method has the following drawbacks: 1) Insufficient space utilization: The additional display screens occupy space in the station, which may affect passengers' view and the station's aesthetics.

[0004] 2) Limited view: Passengers have to look up to see, which is a poor experience and the view is easily blocked when crowded.

[0005] 3) Poor interactivity: Existing displays mostly provide one-way information push and cannot provide passengers with personalized interactive services such as query and route planning.

[0006] 4) Lack of resource integration: As the largest continuous facade in the platform area, the display potential of the platform doors has not been developed and utilized, resulting in a waste of media resources. Summary of the Invention

[0007] The purpose of this utility model is to provide an intelligent subway platform door device with multimedia interactive display function, so as to effectively improve the utilization rate of platform space, information service capabilities and passenger experience.

[0008] This utility model adopts the following technical solution: This utility model relates to an intelligent subway platform door device with multimedia interactive display function, including a door structure and a drive control unit for controlling the opening and closing of the door. Its features include: a multimedia display unit, a human-machine interaction sensing unit, a main control processing unit, and a multimedia management server; wherein the multimedia display unit is integrated on or inside the glass panel of the door structure and is used to display dynamic multimedia information; the human-machine interaction sensing unit is disposed on the door frame of the door structure and is used to detect passenger interaction operations and generate trigger signals; the main control processing unit is electrically connected to the drive control unit, the multimedia display unit, and the human-machine interaction sensing unit; and the multimedia management server is communicatively connected to the main control processing unit.

[0009] The multimedia display unit is a transparent display device, including a transparent OLED display or a transparent Micro-LED display. The multimedia display unit is integrated with the glass panel of the door structure by lamination or bonding, so that the light transmission characteristics of the glass are maintained in the non-display state and a high-definition picture is presented in the display state.

[0010] The multimedia display unit includes: an outer glass layer, which is an ultra-thin tempered protective glass; a middle transparent display layer, which is made of a flexible PCB substrate, on which micro LED light-emitting tubes are arranged in a regular hexagonal honeycomb matrix, and micro through holes are provided between the LED light-emitting tubes to form a pixel-light-transmitting composite structure; and an inner layer of transparent encapsulating adhesive layer, which covers the middle transparent display layer.

[0011] The human-computer interaction sensing unit includes one or more of the following sensors: an infrared touch sensor, a camera, a radar sensor, and a microphone array; wherein the infrared touch sensor is embedded around the door.

[0012] The radar sensor is a millimeter-wave radar sensor.

[0013] The device also includes a signal sensing unit, which is electrically connected to the main control processing unit; the signal sensing unit includes a lidar sensor and a train signal receiver.

[0014] The device also includes a physical emergency controller, which is connected to the main control processing unit.

[0015] The frame of the door structure also integrates a speaker and an indicator light strip.

[0016] The beneficial effects of this utility model are as follows: 1) High integration and space saving: The multimedia display function is integrated into the platform door itself, eliminating the need for additional display screens, beautifying the platform environment and freeing up platform space.

[0017] 2) Intuitive Information, Enhanced Experience: Information is located within the passenger's natural line of sight, making it easy to view.

Detailed Implementation

[0024] To further illustrate the technical means and methods adopted by this utility model to achieve its intended purpose, the specific implementation methods, structural features and methods of this utility model are described in detail below with reference to the accompanying drawings and embodiments.

[0025] like Figure 1 , 2 As shown, this utility model relates to an intelligent subway platform door system with multimedia interactive display function, including a door structure 1 and a drive control unit 7 for controlling the opening and closing of the door, and its features also include: The multimedia display unit 2 is integrated on or inside the glass panel of the door structure 1 and is used to display dynamic multimedia information; The human-computer interaction sensing unit 3 is disposed on the door frame of the door structure 1 and is used to detect the passenger's interactive operation and generate a trigger signal; The main control processing unit 4 is electrically connected to the drive control unit 7, the multimedia display unit 2, and the human-machine interaction sensing unit 3, and is used to receive and process the trigger signal and control the multimedia display unit 2 to output the corresponding display content.

[0026] The door structure 1 is equipped with multiple glass doors that integrate multimedia display units 2. Each glass door with integrated multimedia display unit 2 includes a display layer made of transparent OLED display or transparent Micro-LED display. This allows the glass door with integrated multimedia display unit 2 to remain transparent when not displaying, making it easy for passengers to observe the train. When displaying, it can present screen content.

[0027] The human-machine interaction sensing unit 3 is located above or inside the side frame of the door. The human-machine interaction sensing unit 3 includes an integrated infrared touch sensor, camera and microphone. Passengers can use their fingers to touch and "swipe" to view the train timetable at different times, or use gestures to "remotely" zoom in on product details in advertisements, or ask questions such as "How to get to XX station?" via voice.

[0028] The main control processing unit 4 is embedded in the top box of the platform door. It receives interactive signals from various sensors in the human-machine interaction sensing unit 3, processes them, and sends instructions to the multimedia display unit 2 to update the screen, or requests new content from the multimedia management server 6.

[0029] The multimedia management server 6 is located in the station equipment room and manages the display content and scheduling strategies of all platform doors in a unified manner.

[0030] like Figure 3 As shown, the glass door integrating the multimedia display unit 2 adopts a three-layer structure. The outermost glass 21 is an ultra-thin tempered protective glass with an anti-glare (AG), anti-fingerprint (AF) and chemical tempering treatment. It has extremely high hardness (Mohs hardness ≥ 8) and wear resistance, and is used to protect the internal structure from scratches and impacts.

[0031] The intermediate functional layer is a transparent display layer 22, which uses a large flexible PCB substrate. On this PCB substrate, millions of miniaturized flip-chip LEDs are soldered using ultra-precision SMT surface mount technology.

[0032] These LEDs are arranged in a hexagonal honeycomb matrix, with the pixel pitch designed from P3 to P10 as needed. At the center of each hexagon, a micro-hole is drilled using laser drilling technology. The LEDs and the through-holes (light-transmitting points) are evenly distributed and staggered on the same plane, forming a pixel-light-transmitting composite structure. This design allows the entire display unit to achieve a measured light transmittance of 75%-80% when not powered on, allowing passengers to observe the tracks and train conditions without obstruction. When powered on, the light emitted by the micro-LEDs can synthesize high-brightness, high-contrast high-definition images or videos.

[0033] The inner layer 23 is a transparent encapsulating adhesive layer that completely wraps and seals the PCB substrate, serving to provide waterproofing, moisture protection, corrosion protection, and stress buffering.

[0034] In addition to the encapsulation layer, there is a layer of nanophotonic film, which further improves the display contrast, reduces the reflection of external ambient light, and gives the screen hydrophobic and oleophobic (anti-fingerprint) properties.

[0035] This utility model manages processes based on the train's operational status, including the following steps: 1. Normal (between train runs): When the signal sensing unit 5 detects that no train is approaching in the tunnel, the main control processing unit 4 controls the multimedia display unit 2 to display multimedia content normally, such as commercial advertisements, city promotional videos, weather forecasts, etc. When the human-computer interaction sensing unit 3 is activated, passengers can check the route by touching the door or turn the page of advertisements by waving their hands. When a passenger asks "How to get to XX station?", the microphone array in the human-computer interaction sensing unit 3 collects the command, the main control processing unit 4 processes it, and retrieves the navigation information from the multimedia management server 6, displaying the route diagram of the passenger's voice inquiry on the door.

[0036] 2. Before the train enters the station (early warning phase): The lidar sensor 51 or the train signal receiver 52 detects that the train is about to enter the station (e.g., 200 meters from the platform). The main control processing unit 4 immediately sends instructions to all the doors of the platform; Multimedia display unit 2 switches the display content, highlighting the dynamic text and icon prompt "The train is about to enter the station, please do not approach the platform door"; The main control processing unit 4 temporarily disables the touch and gesture functions of the human-machine interaction sensing unit 3 to prevent passengers from being distracted by interaction and to ensure safety; the voice function can be retained for emergency situations.

[0037] 3. Train stops and passenger boarding / alighting phase: After the train has come to a complete stop, signal sensing unit 5 confirms the train's arrival status. The main control processing unit 4 controls the multimedia display unit 2 to switch the display of the train's destination station, next station information, and safety prompts such as "disembarkation first, then boarding"; The brightness of the multimedia display unit 2 is automatically adjusted to ensure that the information is clearly visible. At the same time, the integrated speaker on the door structure 1 plays voice prompts synchronously.

[0038] Signal sensing unit 5 detected that the train has completely left the platform; The main control processing unit 4 immediately resumes the display of multimedia content on the multimedia display unit 2 and re-enables the human-computer interaction function. Once an emergency signal is received from the train control system or the on-duty personnel trigger the physical emergency controller 8, the main control processing unit 4 will interrupt all normal operations.

[0039] The multimedia display unit 2, which controls all doors, displays uniform evacuation indicator arrows and text in full-screen mode at maximum brightness and with flashing. The indicator light strip on door structure 1 turns red and flashes, and the speaker plays an evacuation announcement; As can be seen from the above description of the embodiments, this utility model transforms the platform screen door from a passive isolation facility into an intelligent information node that integrates security protection, information dissemination, media advertising, and interactive services, significantly improving the intelligence level of subway operation and passenger experience.

[0040] Human-machine interaction sensing unit 3 is embedded in the upper crossbeam or left and right columns of the door structure 1. The human-machine interaction sensing unit 3 integrates a variety of sensors, including: An infrared touch sensor frame surrounds the door glass to detect passengers' touch or non-contact gesture operations. Millimeter-wave radar sensors are used to detect passenger approach, lingering, and specific hand gestures, offering advantages such as privacy protection and immunity to ambient light. The microphone array is used to capture passengers' voice query commands; Wide-angle camera (optional, subject to privacy and security assessment): The above sensors are used to assist in gesture recognition and non-identified passenger flow counting.

[0041] Signal sensing units 5 are installed on the platform track side and inside the tunnel to monitor the train's operating status in real time.

[0042] The signal sensing unit 5 includes: a lidar sensor 51 installed at both ends of the platform for accurately detecting the entry and exit positions of the train head; The train signal receiver 52 is used to directly receive timing signals, train schedule information and emergency braking signals from the PIS (Passenger Information System) of the metro train control system.

[0043] The main control processing unit 4 of the system adopts an industrial-grade embedded computer and is installed in the top box of the platform door. This unit is connected to the multimedia display unit 2, human-machine interaction sensing unit 3, signal sensing unit 5 and drive control unit 7 via cables. Its hardware interfaces include RJ45 network port, RS-485 serial port, GPIO port and relay output port, and support multiple industrial communication protocols such as TCP / IP and MODBUS to ensure reliable connection with different devices.

[0044] The main control processing unit 4 communicates with the multimedia management server 6 in the background via the station's industrial Ethernet. The multimedia management server 6 stores and manages all media content that needs to be published, including train timetables, emergency announcements, commercial advertisements, station navigation maps, etc., and can send content to different platform doors according to the strategy.

[0045] In addition, a physical emergency controller 8 (hardware button box) is installed in the station duty room. Its output signal is directly connected to the GPIO port of the main control processing unit 4. It has the highest priority and is used to manually force the display to be turned off or trigger the station-wide emergency broadcast mode in an emergency.

[0046] Through the above specific and detailed implementation methods, this utility model successfully transforms a traditional passive isolation facility into an intelligent information node that integrates high light transmittance safety protection, high-definition media display, intelligent human-computer interaction, and collaborative operation management. Its creativity is particularly reflected in the fact that the structure uses a honeycomb LED and through-hole staggered arrangement design, which perfectly solves the inherent contradiction between "high light transmittance" and "high definition" at the hardware level.

[0047] Perception fusion combines multiple sensing technologies, including radar (privacy protection, unaffected by light), infrared (precise touch), and microphone array (noise-resistant voice), to achieve robust interaction in complex subway environments.

[0048] The control logic proposes a dynamic display and interactive management mode that is deeply linked to the train's operating status, ensuring that safety is always the top priority and achieving a balance between functionality and safety.

[0049] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the protection scope of the present invention.
