Description

Technical Field

[0001] This utility model relates to the technical field of platform guidance devices, specifically a smart passenger guidance device for railway platforms. Background Technology

[0002] The intelligent passenger guidance device on railway platforms is a device that uses advanced technology to provide efficient and accurate guidance services for passengers, improving the efficiency and safety of station operation and management. By transmitting train information and guidance routes to a large guidance screen, it can guide passengers, thereby reducing the workload of platform passenger service staff and meeting passengers' needs for quick, safe, and reliable boarding and alighting.

[0003] As disclosed in utility model publication CN218471448U, a traffic guidance device for displaying parking space availability is described. In this device, a sliding rod can move and drive a rubber scraper to slide on one side of the parking guidance screen body via a connecting plate. At this time, the rubber scraper can clean and wipe the rainwater on the surface of the parking guidance screen body, so that the driver can clearly see the information displayed on the surface of the parking guidance screen body. When the rubber scraper is damaged and needs to be replaced, the bolt can be turned to disengage the bolt from the second threaded groove, thereby achieving the effect of separating the sliding rod and the connecting plate, and then the rubber scraper can be disassembled and replaced.

[0004] The guide screen in the above solution requires cleaning via a cleaning device. The drive device moves the rubber scraper to clean one side of the screen. However, since the rubber scraper can only move up and down, the cleaning method is relatively simple, covering only the vertical area. Horizontal gaps or horizontally distributed stains are difficult to clean, creating blind spots and hindering efficient cleaning of the guide screen. Utility Model Content

[0005] The purpose of this utility model is to provide an intelligent passenger guidance device for railway platforms, in order to solve the problem mentioned in the background art that the cleaning mechanism of the existing guidance device can only move up and down, so the cleaning method of the guidance screen is relatively simple, and it can only cover the vertical area. It is difficult to clean the gaps in the horizontal direction or the stains distributed horizontally, resulting in cleaning blind spots and making it inconvenient to clean the guidance screen efficiently.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a smart passenger guidance device for railway platforms, comprising a system master station. The output of the system master station is wirelessly connected in sequence to a lighting control module, a door display screen, a guidance screen, a motion monitoring module, and a safety warning module. The input of the system master station is electrically connected to an edge computing module. The top and bottom of the guidance screen are slidably connected to a connecting frame via slide rails. A driving mechanism is provided at the top of the connecting frame. A moving block a is slidably connected inside the connecting frame. A cleaning brush is fixedly connected to one side of the moving block a. A guiding mechanism is provided at the top of the cleaning brush. A spring abuts against the bottom of the moving block a. The bottom of the spring a is fixed to the inner side of the connecting frame. A removal groove is provided on one side of the moving block a, and the removal groove is located on one side of the connecting frame. A limiting mechanism for fixing the cleaning brush is provided inside the connecting frame.

[0007] Furthermore, a sensing radar is installed on one side of the guidance screen, and a parking trigger radar is installed on the side of the guidance screen close to the sensing radar. A high-definition infrared PTZ camera is installed between the sensing radar and the parking trigger radar, and the high-definition infrared PTZ camera is fixed to one side of the guidance screen.

[0008] Furthermore, the driving mechanism includes a servo motor that is fixedly mounted on the top side of the large screen via a bracket. The output end of the servo motor is fixed with a threaded rod, the outer side of which is threadedly connected to a cleaning brush. A light rod is slidably connected to the bottom of the cleaning brush.

[0009] Furthermore, the two ends of the light rod are fixed to the guide screen, and the top of the guide screen is rotatably connected to the threaded rod through bearings.

[0010] Furthermore, the guiding mechanism includes a roller rotatably connected to the top of the cleaning brush via a rotating shaft, and multiple sets of protrusions are fixedly connected to one side of the top of the guiding screen, with the bottom of the protrusions being arc-shaped, and the multiple sets of protrusions being equidistantly distributed on one side of the guiding screen.

[0011] Furthermore, the limiting mechanism includes a limiting rod that is slidably connected inside the connecting frame. The outer side of the limiting rod is connected through the moving block a, and the moving block a has a through hole with a diameter larger than that of the limiting rod inside. A connecting block is fixedly connected to the middle of the limiting rod. A handle is provided on one side of the connecting block. Both sides of the handle are fixedly connected to locking blocks. The connecting frame has two sets of locking grooves that match the locking blocks on the side near the handle.

[0012] Furthermore, a movable block b is fixedly connected to one side of the handle, and two sets of springs b are fixedly connected to one side of the movable block b. One end of the spring b abuts against the connecting block, and the outer side of the movable block b is slidably connected to the connecting block. The movable block b is T-shaped.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This intelligent passenger guidance device for railway platforms transmits train information and guidance routes to the guidance screen, and broadcasts guidance information in conjunction with the audio device to guide passengers. The lighting control module can control the changes in light to further guide passengers. The drive device can drive the connecting frame and cleaning brush to move back and forth to clean one side of the guidance screen. The limiting mechanism can facilitate the disassembly and assembly of the cleaning brush.

[0014] By transmitting train information and guidance routes to the guidance screen and broadcasting guidance information through the announcement device, passengers can be guided. The lighting control module can further guide passengers by controlling the changes in the lights. With the help of the motion monitoring module and the safety warning module, passengers can be safely, quickly and reliably guided from the ticket gates to the platform to wait for and board the train, effectively reducing the workload of the platform passenger service staff.

[0015] By starting the servo motor to drive the threaded rod and the connecting frame through threaded transmission, the connecting frame drives the cleaning brush to clean one side of the guide screen. When the roller at the top of the cleaning brush contacts the protrusion, it will be squeezed down. When it is separated, spring A will push the moving block A and the cleaning brush to reset, so that the cleaning brush itself moves up and down. Through the movement in two directions, the cleaning brush can efficiently clean the guide screen.

[0016] Pulling the handle causes the moving block b to press against the spring b, causing the top locking block to disengage from the connecting frame. Then, pulling the handle causes the limiting rod to disengage from the interior of the moving block a, thus releasing the limiting effect on the moving block a. At this point, the cleaning brush can be pulled away from one side of the connecting frame, completing the disassembly of the cleaning brush. Attached Figure Description

[0022] This intelligent passenger guidance device for railway platforms transmits train information and guidance routes to the guidance screen 1 when guiding passengers. Simultaneously, it broadcasts guidance information through an announcement system, thus guiding passengers. The railway platform passenger guidance system utilizes advanced technologies such as communication technology, motion detection technology, and information interaction technology. Combined with the railway EMU timetable, it connects to the station passenger service information system via the lighting control module 18, the EMU information display system, the over-line alarm control system, and a communication interface. It obtains EMU information, controls lighting fixtures, cameras, the guidance screen 1, and platform announcements, and, in conjunction with lighting changes, the door display screen 19, and audible and visual alarms, safely, quickly, and reliably guides passengers from the entrance ticket gates to the platform for waiting and boarding. This effectively reduces the workload of platform passenger service staff and meets passengers' needs for fast, safe, and reliable boarding and alighting.

[0023] Please see Figure 3 and Figure 7The driving mechanism includes a servo motor 3 fixedly mounted on one side of the top of the guide screen 1 via a bracket. A threaded rod 4 is fixed to the output end of the servo motor 3. The outer side of the threaded rod 4 is threadedly connected to the cleaning brush 7. A light rod 5 is slidably connected to the bottom of the cleaning brush 7. The two ends of the light rod 5 are fixed to the guide screen 1. The top of the guide screen 1 is rotatably connected to the threaded rod 4 via a bearing. When the guide screen 1 is used for a long time, dust will accumulate, which will affect the display effect of the guide screen 1. By starting the servo motor 3, the threaded rod 4 is driven to rotate, so that the threaded rod 4 and the connecting frame 2 are threadedly driven. By adjusting the forward and reverse rotation of the servo motor 3, the connecting frame 2 can be driven to reciprocate on one side of the guide screen 1. When the connecting frame 2 moves, it can drive the cleaning brush 7 to move synchronously, so that the cleaning brush 7 can clean one side of the guide screen 1.

[0024] Please see Figure 3 , Figure 4 and Figure 7 The guiding mechanism includes a roller 8 rotatably connected to the top of the cleaning brush 7 via a pivot. Multiple sets of protrusions 9 are fixedly connected to one side of the top of the guide screen 1, with the bottom of each protrusion 9 being arc-shaped. These protrusions 9 are equidistantly distributed on one side of the guide screen 1. To improve cleaning efficiency, multiple sets of protrusions 9 are provided on one side of the top of the cleaning brush 7. When the roller 8 on the top of the cleaning brush 7 contacts the protrusion 9, the cleaning brush 7 is squeezed downwards, causing two sets of moving blocks a6 on one side to press against the spring a10 inside the connecting frame 2. When the roller 8 disengages from the protrusion 9, the spring a10 pushes the moving blocks a6 and the cleaning brush 7 back to their original positions. Thus, the cleaning brush 7 follows... While the connecting frame 2 moves, it also moves up and down. Through these two directions of movement, the cleaning brush 7 forms a mesh-like cross path, which can accurately cover every pixel and corner of the screen, avoiding strip-shaped cleaning blind spots caused by a single trajectory. The guidance screen 1 in railway platforms, stations and other scenarios is often in an environment with dense crowds and continuous dust accumulation. Cleaning needs to be quick and effective. The composite motion can complete the cleaning of the entire screen in a shorter time, reducing the probability of dust from uncleaned areas falling back into cleaned areas for secondary pollution. This ensures that the screen can quickly restore a clear display after cleaning and does not affect passengers' viewing of guidance information.

[0025] The intelligent guidance in this application refers to the ability to guide the large screen 1 to move horizontally while simultaneously performing vertical reciprocating cleaning.

[0026] The above operations facilitate the cleaning of intelligent passenger guidance devices on railway platforms. Example

[0027] Please see Figures 4 to 6 and Figures 8 to 9Based on Embodiment 1, a limiting mechanism for fixing the cleaning brush 7 is also disclosed, the specific structure of which is as follows: The connecting frame 2 is provided with a limiting mechanism for fixing the cleaning brush 7. The limiting mechanism includes a limiting rod 11 that is slidably connected inside the connecting frame 2. The outer side of the limiting rod 11 is connected through to the moving block a6. The moving block a6 has a through hole with a diameter larger than that of the limiting rod 11. A connecting block 12 is fixedly connected to the middle of the limiting rod 11. A handle 13 is provided on one side of the connecting block 12. Both sides of the handle 13 are fixedly connected to the locking blocks 14. The connecting frame 2 has two sets of locking grooves that match the locking blocks 14 on the side near the handle 13. A moving block b15 is fixedly connected to one side of the handle 13. Two sets of springs b16 are fixedly connected to one side of the moving block b15. One end of the spring b16 abuts against the connecting block 12. The outer side of the moving block b15 is slidably connected to the connecting block 12. The moving block b15 is T-shaped.

[0028] Please see Figures 4 to 6 and Figures 8 to 9 When the cleaning brush 7 needs to be disassembled, the intelligent passenger guidance device at the railway platform can move the moving block b15 by pulling the handle 13. The moving block b15 will squeeze the spring b16, and the locking block 14 at the top of the handle 13 will disengage from the connecting frame 2. The handle 13 can be pulled to move the connecting block 12 and the limiting rod 11 downward. When the limiting rod 11 moves, it will disengage from the inside of the moving block a6, thus releasing the limiting of the moving block a6. At this time, the cleaning brush 7 can be pulled to move the moving block a6 towards the side of the removal slot, so that the cleaning brush 7 passes through the removal slot and disengages from the inside of the connecting frame 2, completing the disassembly of the cleaning brush 7. In this way, the cleaning brush 7 can be easily disassembled and assembled.
