Abstract
Description
Technical Field
[0001] This invention relates to the field of high-speed railway transportation facilities technology, specifically to a high-speed railway platform safety protection system, and in particular to a novel platform door system that can be opened and closed in a large manner, can dynamically adapt to the parking positions of different train models, and integrates information display functions. Background Technology
[0002] High-speed rail platforms need to accommodate various train types, each with different door positions, numbers, and spacing. Existing high-speed rail platform doors are mostly fixed or sliding types, which have significant drawbacks: Poor adaptability: The fixed door structure cannot flexibly cope with the changes in the door position of different train formations. In order to be compatible with multiple train models, it is often necessary to choose not to install platform doors or to install an extremely expensive adaptive sliding door system. The latter has a complex structure and great reliability challenges.
[0003] Space occupation: Traditional pillar and fixed door structures occupy platform space both visually and physically, affecting the sense of openness of the platform and passenger flow.
[0004] Information display is fragmented: Train number, carriage number, seat number, and other information are usually provided by fixed signs or a few displays installed on the platform floor. They cannot be dynamically adjusted, the amount of information is limited, and passengers have to look down to find them, resulting in a poor experience.
[0005] Therefore, there is an urgent need for a new platform door solution that can fundamentally solve the problem of door position adaptability while improving space utilization and information service capabilities. Summary of the Invention
[0006] The purpose of this invention is to overcome the shortcomings of the prior art and provide a highly adaptable, space-saving, information display-capable, retractable high-speed rail platform safety door system and its control method that can accommodate different train models with a large opening.
[0007] To achieve the above objectives, the present invention adopts the following technical solution: This invention relates to a large-opening, retractable high-speed railway platform safety door system, characterized in that it comprises: an intelligent drive and control unit, an integrated information display unit, a lightweight, high-strength frame, and a retractable door body, wherein: Intelligent drive and control unit: used to control the lifting and lowering of the door, communicate with the train dispatching system to obtain information such as the type, formation, and precise stopping position of the train that is about to enter the station, and calculate the optimal opening / closing strategy for each door unit; The integrated information display unit is installed on the front of the top box of the system. It has a long strip of high-resolution dynamic information display screen, which is used to dynamically display information such as train number, carriage number, seat number distribution, train operation prompts, and commercial advertisements. The lightweight, high-strength frame consists of an upper top box and embedded columns; the embedded columns adopt a narrow cross-section structure and have a hollow interior for cable routing, reducing the space occupied by the embedded columns on the platform. The retractable door adopts a roller shutter-style storage method. The roller shutter-style door is composed of multiple rigid panels connected by hinges. The rigid panels adopt a hollow design to reduce the direct impact of train wind pressure on the door. The roller shutter-style storage mechanism has a roller shaft at the top, and the drive device drives the roller shaft to rotate, realizing the vertical roller shutter-style lifting and lowering of the door. After the door is lowered, its bottom is locked to the platform sill by a locking unit.
[0008] This invention relates to a control method for a large-opening, retractable high-speed railway platform safety door, characterized in that: the intelligent drive and control unit can employ two methods to control the movement of the roller shutter door, depending on specific needs: Method A: Under normal circumstances, all roller shutter doors remain closed, and the door locking unit securely locks the doors to the station platform, completely enclosing the platform. When the system detects that a train is about to enter and stop, the intelligent drive and control unit immediately calculates the exact position of each train door on the platform. The dynamic information display screen installed on the front panel of the top box of each door unit dynamically displays precise information such as "Train XXXX, Carriage No. 1-X, Current Carriage: X, Business Class: Row 1-X," guiding passengers to wait in an orderly manner. After the train enters the station and comes to a complete stop, the control system opens only the unit doors corresponding to the train doors, forming a passenger boarding passage. During the door's ascent, the door unit status indicator flashes at a predetermined frequency and an audible alarm sounds. After the train departs the station, the system closes all unit doors.
[0009] Method B: Before passengers enter the platform, all doors are retracted into the top box, leaving the platform fully open and providing a wide and unobstructed view. When the system detects that a train is about to arrive and stop, the intelligent drive and control unit immediately calculates the exact position of each train door on the platform. While the station notifies passengers to enter the platform, it only lowers and closes the door corresponding to the current train door position, creating a precise safety isolation zone. A dynamic information display screen installed on the front panel of the top box above each door unit dynamically displays precise information such as "Train XXXX, Carriage Number 1-X, Current Carriage: X, Business Class: Row 1-X," guiding passengers to wait in an orderly manner. After the train arrives and comes to a complete stop, the control system opens the unit door corresponding to the train door position upwards, forming a passenger boarding passage. During the door's ascent, the door unit status indicator flashes at a predetermined frequency and an audible alarm sounds. All station doors remain retracted until the train departs the station, leaving the platform fully open.
[0010] Preferably, in the method, a mechanical manual device is provided on the track side of the lifting door and a manual unlocking key is provided on the platform side, which together form a locking unit for manually raising and lowering the door in case of emergency.
[0011] Preferably, in the method, the lifting door has a self-stop design structure. In the event of a system failure, the self-stop design structure can remain at the fault position at any time and will not descend on its own. It can also be manually raised or lowered to the desired position.
[0012] Preferably, in the method, the lifting door body is equipped with an obstacle detection structure. When there are people or foreign objects below the lifting door body during the closing process, the obstacle detection structure can automatically open and attempt to close again. If the obstacle still exists after three consecutive attempts, the door will remain in the rising and open state and an alarm will be triggered.
[0013] Preferably, in the method, the rigid panels of the door are connected in pairs by hinges, and the hollow design between the panels reduces the direct impact of train wind pressure on the door.
[0014] Preferably, in the method, the rigid panel can be made of aluminum profile stretching or other materials with good rigidity, and the hollow connection design combines transparency and wind pressure resistance.
[0015] Preferably, in the method, the locking unit is an electromagnetic lock or a mechanical bolt mechanism to ensure that the door is securely locked after it falls into place.
[0016] Preferably, in the method, the top dynamic information display screen is set on the front cover of the top box or the side of the embedded column, and adopts a high-brightness LED strip panel or Micro-LED technology to ensure that it is still clearly visible under strong outdoor light.
[0017] Preferably, in the method, the front cover of the top box is provided with a door unit status indicator light corresponding to the door unit, which remains constantly lit when the corresponding door is open, turns off when the door is closed, and flashes at a predetermined frequency and sounds an alarm during the opening and closing of the door.
[0018] The beneficial effects of this invention are as follows: Adaptability: By using the "partial opening" and "full storage" modes, it perfectly solves the global problem of inconsistent door positions for various high-speed rail models, providing a permanent solution with strong versatility.
[0019] Space optimization: With the doors retracted, the platform offers an extremely open and unobstructed view. The narrow column design further reduces visual obstruction and physical space occupation on the platform.
[0020] Information intelligence and integration: The top display screen replaces the existing fixed ground signs in high-speed rail stations. The information can be dynamically updated and is rich in content. It is always located in front of the passenger's natural line of sight, accurately guiding passengers to board the train. The guidance efficiency is extremely high, and at the same time, it creates new media value.
[0021] Safety and efficiency improvements: The system accurately opens and closes doors based on information about trains arriving at the station, providing necessary safety protection while maximizing open space to facilitate passengers' quick boarding and alighting and luggage handling, thus improving evacuation efficiency.
[0022] High reliability: Compared to complex multi-panel sliding door systems, roller shutter drive mechanisms are relatively simple, more reliable, and have lower maintenance costs.

[0025] To further illustrate the technical means and methods adopted by the present invention to achieve its intended purpose, the specific implementation methods, structural features and methods of the present invention are described in detail below with reference to the accompanying drawings and embodiments.
[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, this invention relates to a large-opening, retractable high-speed railway platform safety door system, comprising: an intelligent drive and control unit, an integrated information display unit, a lightweight, high-strength frame, and a retractable door body, wherein: The intelligent drive and control unit is used to control the lifting and lowering of the door 6, communicate with the train dispatching system to obtain information such as the type, formation, and precise stopping position of the train that is about to enter the station, and calculate the optimal opening / closing strategy for each door unit; The integrated information display unit is located on the front of the top box 4 at the top of the system. It has a long strip-shaped high-resolution dynamic information display screen 7, which is used to dynamically display information such as train number, carriage number, seat number distribution, train operation prompts, and commercial advertisements. The lightweight, high-strength frame consists of the upper top box 4 and the embedded column 5. The embedded column 5 adopts a narrow cross-section structure and has a hollow interior design, which can be used for cable routing, reducing the space occupied by the embedded column 5 on the platform 2. The retractable door 6 adopts a roller shutter-type storage method. The roller shutter-type door 6 is composed of multiple rigid panels connected by hinges. The rigid panels adopt a hollow design to reduce the direct impact of the wind pressure of the train 3 on the door 6. The roller shutter-type storage mechanism 10 has a roller shaft at the top, and the drive device 11 drives the roller shaft to rotate, realizing the vertical roller shutter-type lifting and lowering of the door 6. After the door 6 is lowered, its bottom is locked to the platform sill by the locking unit 8. like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, this invention relates to a control method for a large-opening, retractable high-speed railway platform safety door system, including two states: a normal state and a state before passengers enter platform 2. like Figure 2 As shown, under normal circumstances, all doors 6 remain closed, and the door locking unit 8 securely locks the doors 6 onto the station platform 2, completely enclosing the platform. When the system learns that a train 3 is about to enter the station and stop, the intelligent drive and control unit immediately calculates the exact position of each door 3-1 of the approaching train on platform 2.
[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5As shown, the dynamic information display screen 7 installed on the front panel of the top box 4 on the upper part of each door unit 1 dynamically displays accurate information such as "XXXX train, carriage number 1-X, current carriage: X, business class: row 1-X" to guide passengers to wait for the train in an orderly manner.
[0028] like Figure 1 As shown, after train 3 comes to a complete stop, the control system drives the drive mechanism 11 above the door unit 1 at each corresponding position to lift the door 6 and store it in the top storage mechanism 10, precisely forming a boarding passage in front of each door. During the lifting of the door 6, the door unit status indicator light 9 flashes at a predetermined frequency and an audible alarm sounds. For other doorless areas of train 3, the door 6 remains closed.
[0029] like Figure 2 As shown, after the train door 3-1 closes, all the retractable door bodies 6 automatically descend to the platform 2 position and are locked by the locking unit 8, and the platform 2 returns to a completely closed state.
[0030] like Figure 3 As shown, before passengers enter platform 2, all doors 6 are rolled up inside the top box 4, and platform 2 is fully open, achieving a wide and transparent view of platform 2.
[0031] like Figure 4 As shown, when the system learns that a train 3 is about to enter the station and stop, the intelligent drive and control unit immediately calculates the exact position of each train door 3-1 on the station platform 2. While the station notifies passengers to enter the platform 2 to wait for the train, it only lowers and closes the door body 6 of the door body unit 1 corresponding to the current position of the train door 3-1, forming a precise safety isolation zone. For positions without train doors 3-1, the corresponding door body 6 remains in the upper retracted state, which takes into account both reducing the impact of train wind pressure on the platform door and protecting passenger safety risks. Passengers can also quickly determine the stopping position corresponding to the train door 3-1 by observing the closed state of the unit door body 6.
[0032] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the dynamic information display screen 7 installed on the front panel of the top box 4 on the upper part of each door unit 1 dynamically displays accurate information such as "XXXX train, carriage number 1-X, current carriage: X, business class: row 1-X" to guide passengers to wait for the train in an orderly manner.
[0033] As shown in Figure 3, after the train enters the station and comes to a complete stop, the control system drives the drive mechanism 11 of the door unit 1 at each position to lift the door 6 and store it in the top storage mechanism 10. During the rising of the door 6, the door unit status indicator 9 flashes at a predetermined frequency and sounds an alarm. All doors 6 of the station remain in the upper storage state until the train leaves the station, and the platform is in a fully open state.
[0034] As shown in Figure 5, the lifting door 6 is equipped with a mechanical manual device on the track side and a manual unlocking key on the platform side, which together form a locking unit 8 for manually raising and lowering the malfunctioning door 6 in an emergency.
[0035] The lifting door 6 has a self-stop design structure. In the event of a system failure, the self-stop design structure can keep the lifting door 6 at the fault position at any time, preventing it from descending on its own, and it can be manually raised or lowered to the desired position.
[0036] The lifting door 6 is equipped with an obstacle detection structure. When there are people or foreign objects below the lifting door 6 during the closing process, the obstacle detection structure can automatically open and try to close again. If the obstacle still exists after three consecutive attempts, the door will remain in the rising and open state and an alarm will be triggered.
[0037] like Figure 5 As shown, the rigid panels of the door 6 are connected in pairs by hinges. The panel's openwork design reduces the direct impact of train wind pressure on the door 6. The rigid panels can be made of aluminum profiles stretched or other materials with good rigidity. The openwork connection method combines transparency and wind pressure resistance.
[0038] like Figure 5 As shown, the locking unit 8 is an electromagnetic lock or a mechanical bolt mechanism to ensure that the door 6 is firmly locked after it falls into place.
[0039] like Figure 5 As shown, the top dynamic information display screen 7 is located on the front cover of the top box 4 or on the side of the embedded column 5, and adopts a high-brightness LED strip panel or Micro-LED technology to ensure that it is still clearly visible under strong outdoor light.
[0040] like Figure 5 As shown, the front cover of the top box 4 is provided with a door unit status indicator light 9 corresponding to the door unit 1. The indicator light stays on when the corresponding door 6 is open, turns off when the door 6 is closed, and flashes and sounds an alarm at a predetermined frequency during the opening and closing of the door 6.
[0041] 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 invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the inventive concept, and all such modifications and substitutions should be considered within the scope of protection of the invention.
