Description

Technical Field

[0001] This invention relates to the field of rail transit vehicle equipment technology, specifically to a transparent OLED sliding door device and system for use in high-speed trains. Background Technology

[0002] As a modern high-speed transportation tool, the level of intelligence in the internal facilities of high-speed trains is an important indicator of train quality. However, existing high-speed train sliding door systems, such as business class partition doors or carriage entrance doors, still have the following technical deficiencies in terms of intelligent interaction and information integration: I. The disconnect between function and information display. Traditional sliding doors serve only as physical barriers or passageways, lacking information display capabilities. This forces trains to rely on fixed LED screens or posters inside the carriages to display train speed, arrival times, and service information. This separation of information display from the physical door not only occupies valuable public space inside the train but also results in delayed and unintuitive information delivery, failing to provide dynamic and contextualized updates based on train operation status.

[0003] Second, the lack of spatial perception and interaction. Traditional opaque doors obstruct the view, creating a cramped feeling in the carriage. Meanwhile, existing door control systems mostly use simple infrared or mechanical triggers, lacking the ability to perceive complex environments. Especially in the low-frequency vibrations and airflow disturbances generated by high-speed rail operation, existing sensor data often contains a lot of noise, easily leading to misjudgments of passenger intentions (e.g., mistaking passing by for waiting) and missed detection of obstacles, posing safety hazards.

[0004] III. Communication Reliability Bottlenecks in Mobile Carriers. As a reciprocating motion component, sliding doors face the risk of cable fatigue and wear with traditional wired cable carrier transmission methods. Furthermore, the cable carrier is prone to torsional stress concentration during high-frequency reciprocating motion, leading to internal cable breakage. Meanwhile, simple wireless communication struggles to guarantee the real-time performance and integrity of high-definition video stream transmission in the complex electromagnetic environment of high-speed rail. How to achieve stable data transmission with high bandwidth and low latency through algorithm optimization without physical contact remains a challenge that current technologies have not effectively addressed. Moreover, traditional cable carriers not only pose a risk of fatigue fracture, but their large size also limits the compactness of the door design. Summary of the Invention

[0005] The purpose of this invention is to provide a transparent OLED sliding door device and system for use in high-speed trains, so as to solve the problems of functional and information display separation, lack of spatial perception and interaction, and communication reliability bottleneck in the prior art.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A transparent OLED sliding door system for high-speed trains includes a door body and a drive module, as well as a display module, a sensing module, a main control module, and a power supply module for powering all modules, wherein: The display module includes a transparent OLED display screen embedded inside the door body, and a touch interaction unit integrated with the display screen; The sensing module includes a presence sensor and an anti-pinch sensor. The presence sensor is used to collect depth data of the approaching passenger, and the anti-pinch sensor is used to collect obstacle monitoring data in the door movement area. The main control module is connected to the drive module, the display module, and the sensing module via signals, and is equipped with a train communication network interface. The main control module is configured to perform the following operations: The system continuously receives real-time operational data from the train communication network through the train communication network interface. The real-time operational data includes train speed, location information, arrival information, carriage number, and carriage service equipment status information. The system receives and processes depth data from the presence sensor, processes it using a filtering algorithm to suppress vibration interference in the carriage, and determines whether a passenger has the intention to pass based on the processed data. Receive and process touch input signals from the touch interaction unit; Based on the real-time operating data, the determination result of the passage intention, and the touch input signal, the transparent OLED display screen is controlled to switch between normal mode, advertising mode, and interactive mode, generating gating instructions for the driving module and generating corresponding display data and rendering instructions for the display module; The gate control command is sent to the drive module to control the opening and closing of the gate; according to the rendering command, the generated display data is transmitted to the display module through an industrial-grade wireless communication protocol, and the transmission reliability is ensured based on a data integrity verification mechanism.

[0007] Furthermore, the determination of whether a passenger has the intention to travel based on the processed data specifically includes: Based on the processed data, calculate the displacement change of the target within the preset time window; When the displacement change is less than a preset threshold and the duration exceeds a preset time, it is determined that there is an intention to pass; otherwise, it is determined that there is no intention to pass.

[0008] Furthermore, the generation of gating instructions for the drive module includes: When it is determined that there is an intention to pass, or the touch input signal is a door opening operation, an door opening command is generated as the door control command; when the touch input signal is a door closing operation, a door closing command is generated as the door control command. During the process of controlling the door to move based on the door control command, obstacle monitoring data from the anti-pinch sensor is processed in real time. When it is determined that an obstacle has entered the preset safe area, an emergency stop and retraction command is immediately generated as the door control command. After the door moves to full opening based on the opening command, a delay timer is started. If the intention to pass is not determined again during the delay period and there are no continuous obstacles in the preset safe area, a closing command is automatically generated as the door control command.

[0009] Furthermore, in the normal mode, the display screen is transparent, and the real-time operating data is displayed at its edges or in parts.

[0010] Furthermore, the interaction mode is triggered when the presence sensor detects a passenger entering a preset monitoring area, controlling the transparent OLED display screen to display an interactive interface including a virtual door open button, a door close button, or an information query button.

[0011] Furthermore, the advertising mode is triggered when the arrival information contains a train stopping status indicator or when a specific crew member touch input signal is received, controlling the transparent OLED display to switch to a semi-transparent or opaque state and playing the corresponding display data.

[0012] Furthermore, the main control module is also configured to execute the following scenario linkage logic: When the arrival information indicates that the train is about to enter the station, a rendering instruction is generated to control the transparent OLED display to highlight the station and transfer information. When the status information of the carriage service equipment indicates a change in the occupancy status of the restroom, a rendering instruction is generated to control the updating of the corresponding status identifier.

[0013] Furthermore, the sensing module also includes an ambient light sensor for collecting light intensity data inside the carriage; the main control module is also configured to receive the light intensity data and dynamically adjust the display brightness of the screen based on the data.

[0014] Furthermore, the power module includes a top sliding contact line and a corresponding brush for supplying power to the moving door, and the output cable of the power module is fitted with a metal corrugated tube for physical protection and electromagnetic shielding. The industrial-grade wireless communication protocol is either Wi-Fi 6 or millimeter-wave wireless communication protocol.

[0015] Another object of the present invention is to provide a transparent OLED sliding door device for use in high-speed trains, including the aforementioned transparent OLED sliding door system for use in high-speed trains.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. Improved sensing accuracy and safety. This invention effectively solves the problem of sensor data distortion in the high-frequency micro-vibration environment of high-speed rail by introducing a vibration noise suppression algorithm based on Kalman filtering and displacement vector calculation. The system can accurately distinguish between passengers' waiting intentions and passing behavior, significantly reducing the false trigger rate; at the same time, combined with the anti-pinch area matrix constructed by LiDAR, it achieves millisecond-level response to obstacles, improving the safety of sliding door operation.

[0017] 2. Deeply intelligent information display has been achieved. Unlike traditional physical screens, this invention uses a scenario-based mapping algorithm to transform train network data, such as deceleration upon entering a station and restroom occupancy, into a real-time visual rendering strategy for the doors. This door-as-screen logic not only eliminates the spatial barrier of traditional opaque doors but also significantly saves interior space and provides a seamless interactive experience.

[0018] 3. It alleviates the communication bottleneck of mobile devices. By employing a combination of industrial-grade wireless transmission, data integrity verification, and selective retransmission mechanisms, this invention ensures highly reliable transmission of high-definition video streams during the reciprocating motion of sliding doors without relying on physical wired interfaces. This purely logical fault-tolerant mechanism perfectly adapts to the complex electromagnetic environment and mechanical motion characteristics of high-speed rail, ensuring the long-term stability of the system. Attached Figure Description

[0019] Figure 1 This is a system structure block diagram of the present invention; Figure 2 This is a schematic diagram of the logic flow of the main control module of the system described in this invention. Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention. Furthermore, the technical features involved in the various embodiments of this invention described below can be combined with each other as long as they do not conflict with each other.

[0021] like Figure 1 As shown, this embodiment provides a transparent OLED sliding door system for high-speed trains. This system innovatively transforms the traditional, single-function physical partition into an intelligent, transparent information interaction node. The system is mainly composed of a door body and a deeply integrated drive module, display module, sensing module, main control module, and power supply module.

[0022] The door adopts a high-strength, lightweight frame structure, with the central area made of transparent or highly transparent material (such as tempered glass) to provide a carrier for the display module. This is the physical basis for achieving visual transparency, fundamentally solving the sense of spatial separation caused by traditional opaque sliding doors. The drive module, including guide rails, a motor, and a transmission mechanism, is installed on the top or side wall of the carriage to drive the door to move smoothly along the guide rails, achieving physical separation and opening of space.

[0023] The core of the display module is a transparent OLED display embedded within the door frame, achieving integrated spatial transparency and information display. When not powered, the display is highly transparent, seamlessly blending into the door structure; when powered on, it dynamically displays various information, transforming the door itself into a large, space-saving transparent information window, solving the problems of missing information display and space occupation. The display surface integrates high-precision touch interaction units, such as projected capacitive touch films, providing a direct hardware interface for subsequent interactive modes and laying the foundation for improved user experience. Considering the high-frequency vibration of the door and the heat generation characteristics of the transparent OLED display, this embodiment also includes heat dissipation and vibration resistance design. A transparent thermally conductive interface material is provided on the back of the transparent OLED display to conduct heat to the door's metal frame for auxiliary heat dissipation. Simultaneously, the display is connected to the door frame via a high-damping transparent elastic connector to isolate high-frequency vibration.

[0024] The perception module includes multiple sensors. Specifically, a presence sensor, employing a Time-of-Flight (ToF) sensor, is mounted on the top of the door to collect depth data of passengers in the area in front of the door. Its monitoring range constitutes a preset monitoring zone. An anti-pinch sensor, using a LiDAR array, is integrated into the moving edge of the door to scan and collect obstacle monitoring data in the door's moving area in real time; its scanning range is defined as a preset safety zone.

[0025] The sensing module endows the system with environmental awareness and security protection capabilities. The sensing module integrates multiple types of sensors: The presence sensor, employing a Time-of-Flight (ToF) sensor, is mounted at a downward 45° angle at the center of the top of the door. By adjusting the sensor's transmission power and lens focal length, the preset monitoring area is set as a fan-shaped region with a radius of 0.5 to 3 meters centered on the front of the door, and the lower boundary of this area is 0.1 to 2.2 meters above the ground. This area covers the typical path of passengers approaching the door from the corridor, effectively capturing waiting passengers while filtering out interference from debris or excessively tall objects on the ground.

[0026] The anti-pinch sensor uses a LiDAR array and is integrated at the moving edge of the door. LiDAR has the advantages of accurate ranging and fast response, and can construct a non-contact preset safety area for real-time scanning and collecting obstacle monitoring data, which is the key to achieving a high-security anti-pinch function. The LiDAR array scan data is constructed into a two-dimensional or three-dimensional point cloud matrix, that is, the anti-pinch area matrix. The main control module determines the intrusion of obstacles by detecting the change in the point cloud density in a specific area of the matrix.

[0027] The anti-pinch sensor uses a LiDAR array and is integrated at the moving edge of the door. The LiDAR array is evenly distributed on both sides of the door edge at an interval of 5 cm to ensure that the scanning blind area is smaller than the size of common obstacles. The preset safety area is defined as a rectangular three-dimensional space that extends 20 cm outward based on the side of the door and covers the full stroke of the door in the vertical direction. The main control module maps the point cloud data output by LiDAR to this preset coordinate system for real-time modeling, and constructs a two-dimensional or three-dimensional anti-pinch area matrix. The system determines the intrusion of obstacles by detecting the sudden change in the point cloud density in a specific area of the matrix. For example, when a solid object with a diameter greater than 2 cm enters this matrix area, the anti-pinch logic is immediately triggered.

[0028] The ambient light sensor is used to sense the change in carriage lighting and provide data input for realizing the adaptive adjustment of the screen brightness.

[0029] The main control module, as the decision-making center of the entire system, uses an industrial-grade ARM Cortex-A series multi-core processor as the main controller. This controller is respectively connected to all units in the drive module, display module, and sensing module by signal. This controller has powerful computing power to run complex tasks such as filtering algorithms, intention recognition, and multi-mode decision-making simultaneously. At the same time, a train communication network interface, such as an MVB bus interface or a train Ethernet interface, is integrated on the main controller board for accessing the train communication network and connecting to the train main control system. This makes this door system no longer an information island, but can be deeply integrated into the train intelligent network, obtain real-time operation data, and provide the possibility for realizing scenario linkage.

[0030] The main control module is configured to execute a complete perception-decision-execution logic process, as Figure 2 shown, specifically: (1) Continuously receive real-time operation data from the train communication network through the train communication network interface. The real-time operation data includes train speed, position information, arrival information, carriage number, and carriage service equipment status information.

[0031] Specifically, real-time operational data is received from the train's main control system via the train communication network interface. These data packets, after parsing, include: the train's current operating speed (vehicle speed), GPS / odometer location information, arrival information from the planned timetable, carriage number, and carriage service equipment status information. The arrival information includes the next station name, estimated arrival time, and whether it includes a stop status indicator, while the carriage service equipment status information includes the toilet occupancy / availability status code.

[0032] (2) Receive and process the depth data from the presence sensor, process it by a filtering algorithm for suppressing carriage vibration interference, and determine whether the passenger has the intention to pass based on the processed data.

[0033] Specifically, the main controller performs specialized processing on the ToF depth data to suppress the low-frequency vibration interference unique to high-speed train carriages. It applies filtering algorithms designed to suppress carriage vibration interference, such as a digital filter combining high-speed moving average and band-stop filtering, to smooth the original depth data containing vibration noise, extracting stable target depth data, i.e., the processed distance information. This algorithm, like noise-canceling headphones, filters out signal jitter caused by vibration, extracting the passenger's true and stable depth data, laying the foundation for subsequent accurate judgment. Preferably, the filtering algorithm uses a Kalman filter model. The state vector is set as [z,v], where z is the target distance and v is the relative velocity. Based on the vibration frequency characteristics of high-speed train carriages, typically 5-20Hz, the process noise covariance matrix Q and the observation noise covariance matrix R are set. Through prediction and update iterations, periodic displacement noise caused by wheel rolling over track joints is filtered out, outputting a smooth depth data estimate. Based on the filtered stable depth data, the main controller executes the following quantization judgment logic: Within a preset time window, such as 0.5 seconds, the main target is continuously tracked, and its displacement change within that window is calculated. This displacement change essentially reflects the target's lateral movement speed in front of the door and is a key indicator for distinguishing between stopping and passing by. A displacement threshold, such as 5 cm / 0.5 seconds, and a duration threshold, such as 1 second, are set. The key to the judgment logic is that when the displacement change is less than the threshold, it indicates that the target is nearly stationary, and if this state continues for more than the duration threshold, the system determines that it has the intention to pass. Conversely, if the displacement is large, indicating rapid passage, it is determined that there is no intention to pass. The formula for calculating the displacement change Δd is: ,in The distance after filtering at the current moment. The distance is the starting point of the time window. The displacement change Δd is calculated based on the depth data sequence within the preset monitoring area. A threshold is set. ,when Furthermore, if the duration T > 1 second, it is determined to be a stay. This algorithm transforms the ambiguous short-term stay behavior into clear, programmable quantitative rules, perfectly solving the interactive problem of intelligently judging passenger intentions.

[0034] (3) Receive and process touch input signals from the touch interaction unit. The signal contains touch coordinate information and can be interpreted as an operation of virtual buttons such as "open door", "close door", and "information query".

[0035] (4) Based on the real-time running data, the determination result of the passage intention and the touch input signal, control the transparent OLED display to switch between normal mode, advertising mode and interactive mode, generate gating instructions for the driving module, and generate corresponding display data and rendering instructions for the display module.

[0036] The main controller makes a comprehensive decision based on the real-time operating data, the determination result of the passage intention, and the touch input signal, including: The display control decision determines the current display mode to be activated and generates corresponding display data and rendering instructions accordingly. The rendering instructions determine the displayed content, layout, transparency, etc. The display mode intelligently switches between normal mode, advertising mode, and interactive mode.

[0037] The gating decision generates gating commands for the drive module. The generation of these gating commands reflects a design principle that combines automated convenience with manual safeguards, prioritizing safety. Specifically, this includes: The door opening mechanism features dual triggers, supporting both the convenience of smart sensing and the certainty of manual operation. An opening command is immediately generated when an intention to pass is detected (automatic sensing) or a touch signal clearly indicating a door opening operation is received.

[0038] The active door closing mechanism is primarily triggered by receiving a touch signal indicating that the door is closing, thus respecting the passenger's right to control the door.

[0039] The active anti-pinch safety system processes LiDAR data in real time during door movement, comparing it with the boundary coordinates of a preset safety zone. When an obstacle is detected encroaching on the preset safety zone, the system doesn't simply stop abruptly; instead, it generates an emergency stop and retraction command. This slight retraction creates a safety buffer space, further reducing the risk of pinching injuries and demonstrating a level of safety design depth beyond ordinary anti-pinch functions.

[0040] The system features a delayed automatic closing mechanism. After the door is fully open, a 10-second delay timer is initiated. During this delay, the system continuously determines the user's intention and comprehensively monitors the safety zone. If no further intent to pass is detected during this period, and the anti-pinch sensor confirms that there are no persistent obstacles within the preset safety zone, the system automatically generates a closing command. Adding the condition of no persistent obstacles effectively prevents the risk of the door suddenly closing while passengers are passing through quickly, achieving a perfect balance between energy-saving automation and passenger safety.

[0041] (5) The gate control command is sent to the drive module to control the forward and reverse rotation and start and stop of the motor, thereby controlling the opening and closing of the gate; according to the rendering command, the generated display data is transmitted to the display module through an industrial-grade wireless communication protocol such as Wi-Fi 6 or millimeter-wave communication protocol. To ensure the reliability of transmission in the mobile environment, this embodiment adopts an application layer data integrity verification mechanism: when the main control module sends the display data packet, it calculates the CRC32 check code for each frame of display data payload and encapsulates the check code in the header of the data packet; before parsing the data, the receiving end of the display module recalculates the check code of the received data and compares it with the check code in the packet header. If they match, it sends an ACK confirmation signal back to the main control module and performs business processing; if they do not match or no feedback is received after timeout, the main control module starts a selective retransmission mechanism to retransmit only the lost or damaged data packet fragments, rather than the entire screen data. Through this retransmission strategy based on data integrity verification, the data packet loss problem caused by the obstruction of the high-speed rail body and the multipath effect is effectively overcome. After receiving the data, the local processor of the display module controls the transparent OLED screen to perform rendering display.

[0042] At this point, the system has completed a full intelligent cycle from perceiving the environment, understanding the intent, making a decision, to executing feedback.

[0043] Furthermore, the system's display control is not static but dynamically switches between three intelligent modes based on the operating scenario and passenger interaction, achieving a high degree of functional integration, specifically: Normal mode, also known as transparent information mode, is the default state. The control screen operates in a transparent state, dynamically displaying real-time running data at the edges or in specific areas. This mode maximizes visual transparency while providing necessary information, representing the normal state of a transparent information window.

[0044] The interactive mode is also known as the proactive service mode. It is automatically triggered when a sensor detects a passenger entering a preset monitoring area, such as 1 meter away. This design ensures the interactive interface only appears when needed, preventing the screen from being constantly occupied by virtual buttons, which would negatively impact aesthetics and usability. The interface provides clearly defined virtual buttons, offering a clear and reliable alternative operation path for passengers who are not accustomed to or unable to trigger automatic sensors, ensuring the system's interactive inclusiveness.

[0045] The advertising model encompasses both business and promotional activities. Triggering conditions are intelligently matched to usage scenarios: when the train stops at a station, the system utilizes the peak passenger attention time during the stop period; alternatively, it can be manually triggered by the train attendant or sent via a terminal. Once triggered, the screen can switch between semi-transparent and opaque states to display content. This model creates new commercial value-added opportunities for the train without affecting core transit functions.

[0046] The aforementioned modes are not entirely mutually exclusive; the system is designed with intelligent arbitration logic. For example, if an interactive mode is triggered during an advertisement, the system can prioritize responding to the passenger's interaction needs; information in normal mode and information in interactive mode, such as arrival prompts, can be displayed simultaneously in layers and areas. This collaborative capability allows a single screen to carry complex and multi-dimensional information and services, offering the advantage of highly integrated functionality.

[0047] Furthermore, the main control module is also configured with scenario-based linkage logic, which reflects the deep integration of the system with train operation. Specifically, the main controller continuously parses real-time operating data. When a trigger signal indicating an upcoming station arrival is detected, such as the next station in the arrival information matching the GPS location and the distance being less than a threshold, a rendering instruction is automatically generated to control the screen to highlight the station name and transfer route map. When the status information of the carriage service equipment indicates a change in the occupancy status of the restrooms, such as changing from 0 to 1, a rendering instruction is automatically generated to control the updating of the status indicator in the corresponding area of ​​the screen, such as changing from an unoccupied icon to an occupied icon.

[0048] Furthermore, the sensing module also includes an ambient light sensor for collecting light intensity data inside the carriage; the main control module is also configured to receive the light intensity data and dynamically adjust the display brightness of the screen based on the data. Specifically, the ambient light sensor is installed on the side of the door facing the interior of the carriage to continuously collect light intensity data inside the carriage. The main controller receives the light intensity data from the ambient light sensor and dynamically adjusts the PWM (Pulse Width Modulation) duty cycle of the transparent OLED display screen using a PID control algorithm based on the data, achieving smooth and adaptive adjustment of the display brightness. For example, it automatically dims the screen when driving at night to avoid glare; and automatically brightens the screen when entering a well-lit platform to ensure information visibility.

[0049] Furthermore, the power module is responsible for supplying power to all modules. Considering the need for door movement, a top-mounted sliding contact line is used. Unlike the cable chain structure that relies on repeated bending of flexible cables, the sliding contact line draws power through rigid power supply rails and brushes on the door via surface or line contact. This completely eliminates the fatigue stress concentration problem caused by repeated bending and twisting of flexible cables in the cable chain structure, and also results in a more compact structure. Specifically, power supply rails are laid in parallel alongside the guide rails on the top of the carriage, and the door draws power through brushes. All power supply cables are sheathed in corrugated metal conduits, which not only provides physical protection against wear from frequent bending and vibration, but also electromagnetic shielding to suppress interference from the strong electromagnetic environment of the high-speed rail system's internal circuitry. The power module converts the onboard high-voltage electricity into the operating voltage required by each module.

[0050] The industrial-grade wireless communication protocol is either Wi-Fi 6 or millimeter-wave wireless communication. To ensure link stability during movement, the system employs an RSSI-based signal strength roaming mechanism. When the gate movement causes the current AP signal strength to drop below -70dBm, the main control module actively triggers a roaming switch to an adjacent AP. For millimeter-wave communication, the system uses beamforming technology to track the gate's position and maintain a directional link connection. Simultaneously, the display data packets are encapsulated using the UDP protocol, and forward error correction (FEC) coding is added at the application layer to counteract multipath interference from the high-speed train. Combined with the CRC32 checksum and ACK feedback mechanism described above, the system constructs a reliability assurance system for verification, confirmation, and retransmission. In particular, for gate control commands with extremely high real-time requirements, the system employs lightweight parity checking and sets the highest priority QoS strategy to ensure ultra-low latency and absolute reliability of command transmission.

[0051] Based on the above system, this embodiment provides a transparent OLED sliding door device for high-speed trains, including a physical frame, the system modules as described above, and an external protective shell. As a standardized prefabricated unit, this device can be directly embedded into the doorway of a high-speed train carriage. Internally, the main control module and power module are fixed by shock-absorbing brackets, forming an active intelligent terminal integrating physical separation, intelligent passage, information dissemination, human-computer interaction, and safety protection.
