Description

Technical Field

[0001] The present application relates to the technical field of urban rail transit platform safety protection, and in particular to a rope-type platform lifting safety door system. Background Art

[0002] With the rapid development of public transportation modes such as rail transit, urban subways, and high-speed rail, the importance of platform safety management, as the transitional space between trains and passengers, has become increasingly prominent. To ensure the personal safety of passengers while waiting for and boarding trains, and to prevent people from accidentally entering the track area, some urban rail stations and high-speed rail stations have gradually introduced platform safety doors or platform screen door systems. These provide a dual protection measure of physical isolation and visual cues, improving platform operational safety and management efficiency.

[0003] Currently, the most commonly used platform safety door systems are primarily rigid structures, often combining a fixed door body with movable door leaves, opening upon arrival and closing before departure. Due to their closed structure and strong door body rigidity, these systems offer a certain degree of physical barrier effectiveness. However, they have several limitations in practice. For example, they occupy a significant amount of space at the platform's edge, making construction complex and unsuitable for compact platform layouts. Furthermore, the fixed door structure can cause misalignment between the door body and the train door if a train stops and shifts, significantly impacting passenger boarding and alighting efficiency and even posing a safety hazard.

[0004] Therefore, how to design a platform protection system with a more compact structure, small footprint, and easy construction, installation, and adjustment has become a key technical issue in improving the adaptability of existing platform safety door systems. Summary of the Invention

[0016] Compared with the prior art, this application has the following beneficial effects: 1. The present application provides a rope-type platform lifting safety door system. The present application adopts a distributed combination structure composed of column assemblies and barrier rope arrays, which shows higher flexibility and adaptability compared to the traditional closed rigid safety door layout. The column assemblies are arranged at a certain interval along the edge of the platform, which avoids the large-scale encroachment of continuous metal door panels on the platform passage space, and also provides an adaptability basis for platforms of different lengths and special-shaped structures. The barrier rope array is arranged between adjacent column assemblies to form an effective physical isolation unit, which is not only convenient for modular disassembly and on-site assembly, but also conducive to the flexible configuration of the length of the isolation area according to the actual conditions of the platform.

This structural design allows the adjustment of the spacing of the barrier ropes and the lifting and lowering of the barrier rope array as a whole to be physically integrated on the column assembly and deployed, thereby facilitating the control of the barrier rope array and the multi-form adjustment of the barrier ropes, which is not only convenient to control but also stable in execution. The second driving mechanism is arranged inside the column assembly, and can drive the first driving mechanism to slide in the vertical direction to achieve the lifting and lowering of the entire barrier rope array; while the first driving mechanism can adjust the relative spacing between the barrier ropes, and in cooperation with the lifting and lowering of the barrier rope array as a whole, achieve the switching between the protection state and the passage state while better saving space.

[0027] like Figures 1-9 As shown, an embodiment of the present application provides a rope-type platform lifting safety door system, including a plurality of column assemblies 100 arranged at intervals along the edge of the platform and a barrier rope array 200 arranged between adjacent column assemblies 100, and the barrier rope array 200 is composed of a plurality of barrier ropes 210.

[0028] Each column assembly 100 is provided with a driving mechanism 300 for driving the barrier rope array 200 to rise and fall as a whole and adjust the spacing between the barrier ropes 210; the driving mechanism 300 includes a first driving mechanism 310 installed on the column assembly 100 for adjusting the spacing between the barrier ropes 210 of the barrier rope array 200 and a second driving mechanism 320 for controlling the overall rise and fall of the first driving mechanism 310. The driving mechanism 300 is electrically connected to a control unit 400 to control the rise and fall of the barrier rope array 200 and the change in the spacing between the barrier ropes 210. Each column assembly 100 is also provided with a perception detection component 500 for detecting passenger crossing behavior and the approaching or arriving status of a train, a warning component 600 for warning and reminding, a guide information component 700 for displaying passenger guidance information through an electronic screen, and a communication control component 800 for realizing data communication between the control unit 400 and an external platform dispatching system.

[0029] This embodiment adopts a distributed combination structure consisting of column assemblies 100 and barrier rope arrays 200, which exhibits higher flexibility and adaptability compared to the traditional closed rigid safety door layout. The column assemblies 100 are arranged at a certain interval along the edge of the platform, avoiding the large-scale encroachment of continuous metal door panels on the platform passage space, and also providing an adaptable basis for platforms of different lengths and special shapes. The barrier rope arrays 200 are arranged between adjacent column assemblies 100 to form an effective physical isolation unit, which is not only convenient for modular disassembly and on-site assembly, but also facilitates the flexible configuration of the length of the isolation area according to the actual conditions of the platform. This structural configuration, while meeting the basic protection function, helps to reduce the weight of the overall system and reduce the operational burden during transportation and construction.

[0030] This embodiment also utilizes a dual-drive structure within the drive mechanism 300, consisting of a first drive mechanism 310 and a second drive mechanism 320, which respectively handle the functions of adjusting the spacing between the barrier cords 210 and raising and lowering the barrier cord array 200. This structural design allows both the spacing adjustment of the barrier cords 210 and the raising and lowering of the barrier cord array 200 to be physically integrated within the column assembly 100. This facilitates control of the barrier cord array 200 and its multi-position adjustment, providing both convenient control and stable operation. The second drive mechanism 320, located within the column assembly 100, drives the first drive mechanism 310 to slide vertically, raising and lowering the barrier cord array 200. The first drive mechanism 310, by adjusting the relative spacing between the barrier cords 210 and coordinating the raising and lowering of the barrier cord array 200, achieves a space-saving transition between the protective and passable modes.

[0031] In addition, this embodiment integrates the sensing and detection component 500, the warning and alert component 600, the passenger guidance information component 700, and the communication and control component 800 on each column component 100. The control unit 400 uniformly performs data processing and operational command control, constructing a platform lifting safety gate system that integrates status perception, information prompts, and external communication. The sensing and detection component 500 can monitor passenger crossing behavior and train approach status, providing data basis for operating state switching; the warning and alert component 600 uses a combination of lights and buzzers to remind passengers of safety dynamics; the passenger guidance information component 700 displays train numbers and arrival information on electronic screens, guiding passengers to wait for and board trains in an orderly manner; and the communication and control component 800 enables the system to maintain effective data exchange with the station dispatching platform. The unified integration of these modules on the column component 100 not only simplifies equipment layout and cable laying, but also helps improve the system's internal response efficiency and external information connectivity, providing practical support for the deployment of safety systems in intelligent stations.

[0032] In some embodiments, the first drive mechanism 310 is a variable pitch slide module, and a connecting plate 311 for connecting the barrier rope 210 is respectively provided on each slide station that can be spaced apart on the variable pitch slide module. The second drive mechanism 320 is a linear lifting drive mechanism installed inside the column assembly 100.

[0033] The second driving mechanism 320 includes a linear guide rail 321 , a lifting slide 322 , a lifting driving motor 323 and a ball screw transmission pair 324 .

[0034] The linear guide rail 321 is vertically arranged inside the column assembly 100, the lifting slide 322 is vertically slidably arranged on the linear guide rail 321 and is connected to the first driving mechanism 310, the lifting drive motor 323 is fixedly installed on the inner bottom of the column assembly 100, and the ball screw transmission pair 324 is driven by the lifting drive motor 323 and connected to the lifting slide 322 to realize the up and down movement of the lifting slide 322.

[0035] In the above embodiment, in the design of the first driving mechanism 310, this embodiment adopts a variable pitch slide module as the first driving mechanism 310, which is used to realize the adjustable spacing arrangement between multiple connecting plates 311, thereby providing flexible spacing adjustment capabilities for the barrier rope 210. Each connecting plate 311 corresponds to one or a group (3-5 as a group is preferred) of barrier ropes 210, which are evenly distributed in sequence on each slide station of the variable pitch slide module. During use, the variable pitch slide module moves symmetrically along the length direction of the variable pitch slide module through the internal linkage transmission structure of each slide station, driving the connecting plates 311 located thereon to synchronously move together or expand. As the position of the connecting plate 311 changes, the fixed point of the barrier rope 210 to which it is connected is adjusted accordingly, so that the relative spacing between the rope segments is changed synchronously. This "variable spacing" structural design overcomes the rigid limitations of traditional fixed structures. Adjusting the spacing of the barrier ropes 210 during use helps create a clearer visual guidance channel, making it easier for passengers to identify permitted areas while waiting and boarding, reducing the risk of accidental trespassing and enhancing a sense of order and safety at the platform edge. Furthermore, the dividing strip formed between the barrier ropes 210 provides a distinct visual demarcation, and the opening and closing changes enabled by adjustable spacing further enhance visual recognition of the platform edge. From the passenger's perspective, both the open and closed states of the channel are easily distinguishable, helping to reduce the risk of accidental trespassing and improving passengers' perception of the platform structure. Furthermore, when the device is raised, the barrier ropes 210 cluster together, effectively reducing the width of the entire barrier rope array, conserving space above the platform edge and allowing for greater margin for equipment deployment above the platform, thereby increasing the system's flexibility in compact deployment.

[0036] Specifically, in this embodiment, the first drive mechanism 310 utilizes a ten-station variable-pitch slide module. This means the module has ten slide stations, each equipped with a connecting plate 311 for connecting the barrier ropes 210. In this embodiment, three barrier ropes 210 are connected to each connecting plate 311. In other words, three barrier ropes 210 form a group, resulting in ten groups of barrier ropes. Adjusting the spacing between the barrier ropes 210 allows for adjustments to be made between each group.

[0037] In this embodiment, the connecting plate 311 is used as a connection carrier for the barrier rope 210, and a variety of methods can be used to achieve a stable connection with the barrier rope 210. One optional structure is that each connecting plate 311 is provided with a plurality of mounting holes for fixing the barrier rope 210. The barrier rope 210 can be passed through and fixed in the mounting hole by fasteners such as a wire rope clamp and a crimping ring, thereby achieving a reliable connection while facilitating later replacement and maintenance. Another structural form is that a rope groove or a card slot structure is provided on the side of the connecting plate 311. After the barrier rope 210 is embedded in the card slot, it is locked by a screw or a pressure plate to form a mechanical locking connection with good anti-vibration and anti-falling capabilities. In addition, an elastic gasket or an insulating layer can be added to the connection part to improve the connection stability and insulation performance. The above connection methods all have the characteristics of simple structure and easy installation, and are suitable for frequent start-stop and high-frequency lifting and lowering operation requirements in platform environments.

[0038] It should be noted that the specific connection method between the connecting plate 311 and the barrier rope 210 is not limited to that in the above embodiment. In actual applications, different connection structures and fasteners can be selected based on the installation environment, material properties, and structural requirements. This application does not impose excessive restrictions on the specific structural design of this part. As long as a stable connection between the barrier rope 210 and the connecting plate 311 is achieved, it shall be considered within the scope of protection of the embodiments of this application.

[0039] Regarding the second drive mechanism 320, this embodiment adopts a linear lifting drive mechanism as the second drive mechanism 320, which specifically includes a linear guide 321, a lifting slide 322, a lifting drive motor 323 and a ball screw transmission pair 324. The second drive mechanism 320 is used to drive the first drive mechanism 310 to achieve smooth lifting and lowering inside the column assembly 100. The linear guide 321 is arranged longitudinally along the column assembly 100, providing a guide basis for the lifting slide 322, making it more stable and with a smaller offset in vertical movement. The lifting slide 322 is connected to the lower part of the first drive mechanism 310, and drives the ball screw transmission pair 324 through the lifting drive motor 323 to realize the lifting and lowering action of the overall structure. This structure can effectively reduce the influence of guide deviation and running resistance during mechanical movement, making the lifting process smoother, reducing the possibility of jamming, and thereby improving the reliability of the overall operation of the system.

[0040] In addition, the first drive mechanism 310 and the second drive mechanism 320 operate independently in structure and do not interfere with each other, thereby enhancing the coordination of functional execution and the accuracy of adjustment. The first drive mechanism 310 is responsible for adjusting the spacing between the barrier ropes 210, while the second drive mechanism 320 is responsible for the overall vertical lifting and lowering of the first drive mechanism 310. This layered drive method avoids the structural conflicts and control difficulties that may be caused by a single mechanism taking on multiple actions at the same time. In addition, this double-layer drive configuration also provides a good structural foundation for the control unit 400 to perform logical judgment and strategy execution, allowing the system to flexibly switch between protection modes according to the train operation stage and platform status, thereby having strong responsiveness and operational stability during actual operation, which helps to improve the safety protection efficiency and operational reliability of the equipment in different scenarios.

[0041] It should be noted that the variable pitch slide module used to adjust the spacing of the barrier rope 210 in this embodiment is a mature product in the existing technology. Its internal structure and specific working principle are already well-known technologies generally known to those skilled in the art. The technical solution of this application does not make structural or functional improvements to the variable pitch slide module itself. Therefore, the internal structure and working details of the variable pitch slide module will not be repeated here.

[0042] In some embodiments, the column assembly 100 includes a protective column 110 and a liftable column extension 120; the protective column 110 is vertically fixedly installed on the platform floor, and a second driving mechanism 320 is provided inside the protective column 110; the column extension 120 is provided in the protective column 110 and can move up and down in the vertical direction of the protective column 110 under the drive of the second driving mechanism 320, and a first driving mechanism 310 is provided inside the extension 120. A lifting gap is provided on the side of the protective column 110 for extending the barrier rope array 200 and providing a lifting and lowering space, and an adjustment gap is provided on the side of the extension 120 for adjusting the spacing of the barrier ropes 210.

[0043] Building on the aforementioned basic structure, this embodiment further describes the column assembly 100. Specifically, the protective column 110 serves as a fixed load-bearing component on the platform floor. Its interior houses and securely mounts the second drive mechanism 320, providing stable support during the lifting process. Accordingly, the liftable column extension 120 slidably fits within the protective column 110, integrating the first drive mechanism 310. Driven by the second drive mechanism 320, the entire column moves upward and downward.

[0044] This nested design of "fixed outer shell, lifting internal mechanism" makes the overall layout of the drive mechanism 300 more compact, saving space at the platform edge and improving structural integration. Furthermore, a lifting slot is provided on the side of the protective column 110, and an adjustment slot is provided on the side of the corresponding column extension 120. These two sets of slots form independent structural channels, providing a clear path for the barrier rope array 200 to move up and down, and also leaving room for adjusting the spacing of the barrier ropes 210, thereby ensuring smoother operation.

[0045] In some embodiments, the barrier rope 210 is made of Kevlar fiber material, and a reflective marking layer is provided on the outer surface of the barrier rope 210 .

[0046] When the first driving mechanism 310 is driven by the second driving mechanism 320 to rise, the barrier rope array 200 is lifted as a whole. At the same time, the first driving mechanism 310 controls the connecting plates 311 thereon to move closer together, so that the spacing between the barrier ropes 210 becomes narrower.

[0047] When the first driving mechanism 310 is driven to descend by the second driving mechanism 320 , the barrier rope array 200 is lowered as a whole. At the same time, the first driving mechanism 310 controls the connecting plates 311 thereon to move relatively apart, so that the spacing between the barrier ropes 210 becomes wider.

[0048] In the above embodiment, by optimizing the material selection and external structure of the barrier rope 210, good improvements have been made in improving the system strength, protective performance and visual guidance capabilities. The barrier rope 210 is made of Kevlar fiber material, which has high tensile strength, excellent toughness and strong weather resistance, and is suitable for long-term use in outdoor environments. Its non-breakable characteristics show greater stability in the face of pulling or impact, which helps to enhance the physical blocking effect when passengers mistakenly enter the track area, thereby reducing the risk of structural damage to the system due to external force collision. In addition, the outer layer of the barrier rope 210 is covered with a reflective marking layer. During operation in the early morning, evening or at night when lighting conditions are weak, it can reflect ambient light, enhance the visibility of the rope body in the field of vision, make it easier for passengers to identify the platform boundary, and play a better guidance and warning role.

[0049] In addition, this embodiment further incorporates the operation mode of the first drive mechanism 310 and utilizes the rope spacing adjustment function achieved by its driven connecting plate 311 to simultaneously adjust the distance between each barrier rope 210 while driving the barrier rope array 200 to rise and fall. This structural design allows the barrier rope array to dynamically switch to a more appropriate configuration during different stages, such as train arrival, parking, passenger boarding and alighting, and train departure. It can form a reasonable spacing in the protective state while maintaining a dense and gathered state in the pass state. This improves the protection coverage while enhancing the convenience of passenger passage, further enhancing the operational adaptability and safety control level of the overall system.

[0050] In some embodiments, the sensing detection component 500 includes an infrared photoelectric sensor 510 and an ultrasonic ranging sensor 520 .

[0051] Among them, the infrared photoelectric sensor 510 includes an infrared photoelectric transmitter and an infrared photoelectric receiver respectively arranged on a pair of adjacent column assemblies 100, and the infrared photoelectric transmitter and the infrared photoelectric receiver are arranged on the column assemblies 100 arranged adjacently, and the infrared photoelectric transmitter and the infrared photoelectric receiver can form a horizontal light beam detection belt covering the area between the barrier rope 210 and the platform floor when the barrier rope array 200 is in the lowered state, which is used to detect whether passengers have crossed the boundary and entered the closed area.

[0052] The ultrasonic ranging sensor 520 is installed at the upper middle portion of the column assembly 100 facing the track, and is used to sense whether the train head enters a preset distance range to determine whether the train is approaching or has arrived at the station.

[0053] The control unit 400 is electrically connected to the infrared photoelectric sensor 510 and the ultrasonic ranging sensor 520 respectively, and is used to receive sensing signals and control the start and stop of the drive mechanism 300 and the working state of the warning component 600 based on the state of approaching passengers or trains.

[0054] In this embodiment, the rope-type platform lifting safety gate system of the present application utilizes an infrared photoelectric sensor 510 and an ultrasonic ranging sensor 520 to construct a collaborative sensing and detection component 500, which helps enhance the system's ability to perceive passenger behavior and train operating status. The infrared photoelectric sensor 510 forms a horizontal beam channel between the infrared transmitting and receiving terminals on adjacent column assemblies 100, covering the barrier rope 210 and the platform floor. When a passenger crosses this channel, the beam is immediately interrupted, enabling rapid identification of crossing-the-line behavior. This structural design facilitates the implementation of sensing detection for timely intervention, thereby better assisting in guiding behavior at the platform edge, thereby reducing the probability of passengers mistakenly entering the track area and improving management initiative. In conjunction with this, the ultrasonic ranging sensor 520 is installed in the upper center of the column assembly 100 on the track side and can sense whether the train head has entered the set distance range through echo ranging. Compared with the traditional method that relies on fixed timing control, this dynamic judgment mechanism is more flexible, helps to improve the matching degree of lifting and lowering actions with the actual operating status of the train, and is more adaptable.

[0055] Infrared and ultrasonic sensors focus on passengers and trains, respectively, working together to form a three-dimensional perception system tailored to different targets. Working in conjunction with the control unit 400, this system precisely triggers the responses of the drive mechanism 300 and the warning and alerting component 600, thereby enhancing the overall system's ability to detect and accurately control changing conditions. During critical moments, such as when trains enter and exit stations and when passengers approach marginal areas, the perception and detection component 500 provides a powerful auxiliary judgment function, further optimizing system stability and enhancing passenger safety.

[0056] In some embodiments, the warning component 600 includes a warning light 610 and a buzzer 620 arranged on the top of the column component 100. The warning light 610 is an LED strobe light that can flash at different frequencies to indicate different operating conditions. The buzzer 620 is a variable frequency electronic buzzer that can emit warning sounds of different frequencies according to the current state.

[0057] When the driving mechanism 300 drives the barrier rope array 200 to be in a lifting and lowering operation state, the warning light 610 and the buzzer 620 work synchronously, prompting the dangerous state through high-frequency flashing and continuous sounding respectively; when the barrier rope array 200 is in a stopped motion state, the warning light 610 flashes at a low frequency and the buzzer 620 stops sounding, so as to realize differentiated warning linkage based on different operating states.

[0058] In the above embodiment, a warning light 610 and a buzzer 620 are introduced into the warning and early warning component 600, and the warning light 610 and the buzzer 620 are controlled by the control unit 400, which can enhance the system's ability to remind passengers at different stages of the journey. The warning light 610 uses an LED strobe light, which is set at the top of the column component 100 and has high brightness output and multi-speed frequency switching characteristics. When the drive mechanism 300 performs a lifting action, the warning light 610 switches to a high-frequency flashing state, which can provide an intuitive visual prompt to the platform area; when the driving action ends and enters a stationary state, the flashing frequency decreases, which helps staff quickly identify the current operating status of the equipment. The buzzer 620 is a variable-frequency electronic buzzer that emits continuous high-frequency sound during the lifting process, forming a synchronized audio-visual signal with the warning light 610 to jointly remind platform passengers to pay attention to safety.

[0059] When the system is inactive, buzzer 620 stops sounding, effectively reducing noise interference and helping to maintain a quiet atmosphere on the platform. This audio-visual warning design not only complements each other in form but also functionally reflects a dynamic response based on state perception. By combining differentiated control with logical switching of operating states, the entire system becomes more targeted and real-time in passenger guidance, helping to improve the ability to respond to emergencies and reduce the probability of unsafe behavior caused by misjudgment or distraction. This design also further expands the application scenarios of the warning component 600, providing a good adaptation foundation for diverse station operating environments.

[0060] In some embodiments, the passenger guidance information component 700 includes an electronic display screen 710 installed on the front side of the column component 100, and the electronic display screen 710 is used to display train number and arrival time information.

[0061] In this embodiment, the passenger guidance information assembly 700 utilizes an electronic display screen 710 positioned on the front side of the column assembly 100, capable of displaying real-time train number and arrival time information, thereby enhancing passengers' ability to understand train dynamics. Electronic display screen 710, positioned within easy reach of passengers, directly displays information such as upcoming train numbers and arrival times. This allows passengers to obtain critical travel information in a timely manner without relying on a distant large screen or broadcast, thus reducing the risk of missed trains and other issues caused by delayed or misjudged information.

[0062] Furthermore, the electronic display screen 710, in conjunction with the warning light 610 and buzzer 620, can integrate visual, auditory, and textual information into the passenger guidance process, making the prompts more comprehensive and clear. When the device is in critical states such as lifting, approaching a train, or when a door is open, the electronic display screen 710 can synchronously display status prompts in real time, forming a multi-dimensional information transmission chain with other components to facilitate timely judgment by passengers. This embodiment, through this information-integrated structural layout, not only simplifies the system structure, but also improves the efficiency and accuracy of waiting guidance, enhancing the orderliness of platform operations and the friendliness of service.

[0063] In some embodiments, the communication linkage control component 800 includes a communication module arranged inside the column component 100. The communication module establishes a data connection with the external platform dispatching system through wired or wireless means, and is used to receive train entry information and linkage control instructions. The communication module supports data interaction with cloud servers, local central control terminals and mobile handheld terminals to achieve multi-terminal linkage control with the platform dispatching system; the control unit 400 controls the driving mechanism 300 to drive the barrier rope array 200 to rise and fall based on the train entry information and control instructions received by the communication module, and synchronously links the warning and early warning component 600 and the guide information component 700 to perform status switching and information prompts.

[0064] In the above embodiment, the communication and control assembly 800 includes a communication module housed within the column assembly 100, enabling the system to establish a data connection with the external platform dispatching system, thereby enabling information exchange and control linkage between the equipment's operating status and the dispatching system. The communication module can be accessed via wired or wireless means, allowing for flexible deployment based on different application scenarios. It supports data exchange with multiple terminals, including cloud servers, local central control terminals, and mobile handheld devices. This communication capability enables the control unit 400 to promptly activate the drive mechanism 300 to control the raising and lowering of the barrier rope array 200 based on real-time train arrival information or control commands transmitted by the platform dispatching system. It also coordinates operations with the warning and alerting assembly 600 and the passenger guidance information assembly 700 to uniformly respond to changes in train status. This structural configuration enables the system to dynamically respond to key moments such as train approach and docking, coordinating multiple tasks such as protective deployment, passenger reminders, and guidance information updates. This helps improve the responsiveness and operational cadence of various platform devices, further enhancing the overall linkage efficiency and intelligent operational capabilities of the entire safety gate system.

[0065] In some embodiments, the control unit 400 is provided with an intelligent control module for executing a preset control strategy, and the intelligent control module includes a data processing unit and a logic decision unit.

[0066] The data processing unit is used to receive and comprehensively analyze the sensing data collected by the infrared photoelectric sensor 510 and the ultrasonic ranging sensor 520 in real time, as well as the train entry information and linkage control instructions received by the communication module. The logic decision unit controls the drive mechanism 300 to perform the following actions based on the processing results of the data processing unit and according to the preset control strategy: When the platform dispatching system sends a train entry instruction to the communication module and the ultrasonic ranging sensor 520 detects that the train head has entered the preset stopping distance range, the data processing unit integrates and analyzes the received dispatching instruction with the sensing detection data and transmits the result to the logic decision unit. The logic decision unit controls the driving mechanism 300 to keep the first driving mechanism 310 in the descending state, so that the barrier rope array 200 is maintained in the descending protection state with an extended spacing. When the platform dispatching system further sends a train complete stop confirmation command to the communication module, the logic decision unit controls the driving mechanism 300 to drive the first driving mechanism 310 to rise and simultaneously adjust the spacing of the barrier ropes 210 to a reduced state, so that the barrier rope array 200 is in a state where passengers can pass. When the platform dispatching system sends a control instruction that the train is about to depart or has left the station, the logic decision unit controls the driving mechanism 300 to drive the first driving mechanism 310 down again, and restores the spacing of the blocking ropes 210 to the expanded state, thereby rebuilding the protective barrier at the edge of the platform.

[0067] In this embodiment, an intelligent control module is incorporated into the control unit 400, enhancing the system's automatic sensing and response control capabilities. This module comprises a data processing unit and a logic decision unit. The former receives and comprehensively analyzes information collected by the infrared photoelectric sensor 510, ultrasonic ranging sensor 520, and communication module in real time, thereby acquiring dynamic information about passenger behavior and train operation status on the platform. After data fusion, the logic decision unit generates control instructions appropriate for the current operating scenario based on a pre-set control strategy and transmits them to the drive mechanism 300 to activate the first drive mechanism 310. When a train is approaching, stopped, or about to depart, the system issues corresponding raising and lowering commands and, in conjunction with these commands, adjusts the spacing between the barrier ropes 210, enabling the barrier rope array 200 to rapidly switch between protection and passage modes. This configuration not only expands the system's sensing capabilities but also enhances its adaptability to on-site changes. This facilitates more efficient passenger guidance and platform edge protection in actual operations, maintaining system operational stability and control flexibility in a volatile environment.

[0068] In some embodiments, the rope-type platform lifting safety door system of the present application also includes a digital monitoring and simulation component 900, which is arranged in the platform central control terminal or remote monitoring platform, and establishes a data connection with the control unit 400 through the communication control component 800. The digital monitoring and simulation component 900 includes a data acquisition module, a three-dimensional modeling module, and a remote monitoring and fault diagnosis module.

[0069] Among them, the data acquisition module is used to obtain the operating parameters and status data of the driving mechanism 300, the perception detection component 500, the warning component 600 and the guide information component 700 in real time.

[0070] The three-dimensional modeling module is used to build a three-dimensional digital model of the rope-type platform lifting safety door system based on the real-time data obtained by the data acquisition module, so as to realize the simulation and dynamic visualization update of the system operation status.

[0071] The remote monitoring and fault diagnosis module is used to visualize the dynamic model constructed by the three-dimensional modeling module through a graphical interface, and to remotely monitor the system operation status, analyze operation trends, and provide abnormal fault warnings in combination with the data returned by the control unit 400.

[0072] In this embodiment, the digital monitoring and simulation component 900 is introduced to create a digital platform that integrates data perception, three-dimensional modeling, and remote diagnostic capabilities. By establishing data connections with the control unit 400 and the communication and control component 800, the status of key components within the system can be continuously tracked. The data acquisition module is used to obtain real-time operating parameters of the drive mechanism 300, the sensing and detection component 500, the warning and early warning component 600, and the passenger guidance information component 700, and uses these parameters as the basis for modeling and analysis. Subsequently, the three-dimensional modeling module constructs a dynamic model of the rope-type platform lifting safety gate system based on this data, visually displaying operational processes such as lifting motion and protective switching, allowing platform managers to quickly understand the current system status. The remote monitoring and fault diagnosis module further graphically presents the modeling results and, combined with information fed back by the control unit 400, conducts trend analysis and anomaly identification. This structural design enables dynamic status tracking and proactive response to anomalies during system operation, helping to reduce the frequency of failures and improve overall operational visibility and management efficiency.

[0073] The working principle of the rope-type platform lifting safety door system provided in the embodiment of the present application is as follows: During daily use, the rope-type platform lifting safety gate system of the embodiment of the present application continuously exchanges data with the platform dispatching system through the communication and control component 800, receiving real-time train operation status information. When the train has not yet arrived at the station or is in the driving stage, the system's barrier rope array 200 is always in the initial descending state, and the first drive mechanism 310 drives the connecting plate 311 to adjust the spacing between the barrier ropes 210, so that the barrier ropes 210 are in an expanded state, which helps maintain the permeability and protection of the platform edge area and facilitates passengers to observe the dynamics of the track area in advance. During this stage, the perception and detection component 500 continuously monitors passenger behavior and cooperates with the warning and early warning component 600 to issue corresponding light and sound prompts to remind passengers to pay attention to the safe distance.

[0074] As the train approaches the platform, the ultrasonic ranging sensor 520 monitors the locomotive's position in real time. Upon detecting that the train has come to a complete stop, the control unit 400 issues a command to the drive mechanism 300. The second drive mechanism 320 then activates, driving the barrier rope array 200 to rise to the appropriate height relative to the train door. Simultaneously, the first drive mechanism 310 drives the connecting plates 311 to converge toward the center, narrowing the spacing between the barrier ropes 210 and forming a converged rope structure. This creates a clear and distinct passageway for passengers to board and exit the train quickly and safely.

[0075] During a train stop, the barrier rope array 200 remains raised, and the barrier ropes 210 are retracted, effectively reducing the width of the space occupied by the ropes and providing clear safety isolation and traffic guidance at the platform edge. Simultaneously, the electronic display 710 on the passenger guidance information assembly 700 continuously displays the train number and running time, while the warning and alerting assembly 600 maintains a visual reminder with a low-frequency flashing light, helping passengers clearly perceive the current train stop status.

[0076] When the train has finished boarding and disembarking passengers and is about to leave the platform, the control unit 400 sends an action instruction to the drive mechanism 300 again, and the first drive mechanism 310 controls the connecting plate 311 to readjust the spacing of the barrier rope 210 to the expanded state; then, the second drive mechanism 320 drives the barrier rope array 200 to descend as a whole, returning to the initial low-position expanded state, so that the edge area of the platform is restored to the initial protection state to wait for the arrival of the next train.

[0077] During this process, the sensor detection component 500 maintains real-time monitoring of the platform environment and passenger behavior. The intelligent control module comprehensively processes various sensory data and dispatch instructions to precisely control the execution of the drive mechanism 300. Furthermore, the digital monitoring and simulation component 900, through real-time data acquisition and 3D modeling, provides dynamic, visual remote monitoring and trend analysis. This helps managers monitor the system's operating status in real time, promptly identify and resolve potential faults, and enhance system safety and ease of maintenance.

[0078] It should be further explained that in this embodiment, the dynamic adjustment of the spacing between the barrier ropes 210 is achieved through the linkage of the first drive mechanism 310 with the variable-pitch slide module. This design is not based on conventional mechanical structure splicing, but rather a systematic approach that integrates factors such as platform operating conditions, train entry and exit logic, and passenger traffic behavior. This structure not only enables the synchronized pitch change of the barrier rope array 200 during the raising and lowering process, but also demonstrates excellent practical value in improving spatial coordination and passenger guidance. For example, when the train is stationary, the passage formed by the rising and retracting of the barrier ropes 210 facilitates the orderly boarding and alighting of passengers. During the train's movement, the barrier ropes 210 re-widen their spacing and descend to the platform edge, forming a visually open but physical barrier, maintaining its protective function while minimizing the impact on platform visibility. In terms of overall operational logic, structural integration, and dynamic responsiveness, this variable-pitch adjustment mechanism offers outstanding features that cannot be directly achieved by conventional splicing of existing structures, demonstrating its strong innovation and engineering adaptability.
