Description

TECHNICAL FIELD

[0001] The present application relates to the field of alarm protection, in particular to a train approaching alarm protection system and method for level crossing. BACKGROUND

[0002] Railway lines often divide communities, farmland, industrial areas or urban areas, and level crossings are key nodes that cross such physical divisions, allowing vehicles, pedestrians and non-motorized vehicles to cross the railway to the other side. Level crossings are an integral part of the road network (especially local roads and rural roads), ensuring the basic flow of people and goods, connecting areas separated by railways. However, the railway and the road intersect in the same plane, which itself has a conflict point. The train is fast and has a long braking distance. Once an accident occurs (such as a vehicle rushing, a malfunctioning train stopping at the crossing, or a pedestrian mistakenly entering), the consequences are often extremely serious. In order to avoid accidents, most level crossings are equipped with train approaching alarm devices.

[0003] Current train approaching alarm devices have fixed and mobile forms, mainly in the form of loudspeakers shouting, eye-catching light flashing and other sound and light forms to remind and alarm, and do not have physical protection isolation and intelligent alarm protection linkage, resulting in low alarm efficiency and safety level.

[0004] Therefore, there is an urgent need for a level crossing train approaching alarm protection system and method that can physically isolate and intelligently link alarm protection. SUMMARY

[0005] The purpose of the present application is to provide a level crossing train approaching alarm protection system and method to at least solve the problem that current train approaching alarm devices cannot physically isolate and intelligently link alarm protection.

[0006] In order to achieve the above purpose, the technical solution adopted by the present application is: The level crossing train approaching alarm protection system comprises an STP system, a vehicle depot internal dispatching station, a vehicle depot internal dispatching system, a data storage server and an alarm protection device. The station dispatching station inputs locomotive information entering the vehicle depot into the STP system, the STP system synchronously inputs the locomotive information into the vehicle depot internal dispatching system and the alarm protection device through the data storage server, the vehicle depot internal dispatching station arranges internal dispatching machine operation information according to the locomotive information in the vehicle depot internal dispatching system, and the vehicle depot internal dispatching station inputs the operation information into the alarm protection device through the data storage server, and the alarm protection device performs advance protection according to the locomotive information and the operation information. The alarm and protection device includes a server, a power-on magnet, a power-off magnet, signal cables, an automatic lifting and lowering protective rope, a buried audible and visual alarm, and a machine vision system. The power-on magnet is installed in the direction of oncoming traffic at the level crossing, and the power-off magnet is installed in the direction away from oncoming traffic at the level crossing. The automatic lifting and lowering protective rope is installed on both sides of the level crossing and is located below ground level. The buried audible and visual alarm is installed below ground level at the level crossing, and the machine vision system is installed in the protected area of ​​the level crossing.

[0007] Furthermore, firewalls are respectively installed between the alarm protection device and the STP system and the vehicle depot intra-depot dispatching system.

[0008] Furthermore, the firewall is equipped with decoders on the side closest to the alarm protection device.

[0009] Furthermore, a vehicle number recognition mechanism is provided in the oncoming direction of the level crossing, and the vehicle number recognition mechanism is located behind the power-on magnet.

[0010] Furthermore, the power-on magnet includes a first wheel sensor, a first outdoor antenna, and a first monitoring camera. The first wheel sensor is located in the direction of oncoming traffic, the first outdoor antenna is located on the side of the first wheel sensor away from the direction of oncoming traffic, and the first monitoring camera is located on the outside of the track.

[0011] Furthermore, the shutdown magnet includes a second wheel sensor, a second outdoor antenna, and a second monitoring camera. The second wheel sensor is located in the direction of oncoming traffic, the first outdoor antenna is located on the side of the first wheel sensor away from the direction of oncoming traffic, and the first monitoring camera is located on the outside of the track.

[0012] Furthermore, the automatic lifting and lowering protective rope includes an automatic lifting hydraulic structure, a horizontal pull rope, and a protective cover. The automatic lifting hydraulic structure is located below the ground, the horizontal pull rope is located between the automatic lifting hydraulic structure, and the protective cover is located above the automatic lifting hydraulic structure and the horizontal pull rope.

[0013] Furthermore, the buried sound and light alarm includes light and voice alarm components, both of which are installed below ground level, and the surfaces of the light and voice alarm components are at the same elevation as the level crossing.

[0014] A train approach alarm and protection method for level crossings, the steps of which are as follows: The station dispatch console inputs locomotive information entering the depot into the STP system, and the STP system synchronously inputs the locomotive information into the depot dispatch system and the alarm protection device.

If the locomotive or rolling stock runs over the start-up magnet during its entry or exit from the depot, the buried sound and light alarm will trigger an sound and light alarm. The machine vision system intelligently detects and determines whether there are any people remaining in the protected area of ​​the level crossing. After the determination is completed, the automatic lifting and lowering protective rope rises from the rail surface. Once the locomotive passes through the level crossing and crushes the shut-off magnet, the machine vision system intelligently detects and determines whether there are personnel or locomotives remaining in the protected area of ​​the level crossing.

The dispatching console then inputs the operation information into the alarm protection device. Based on the locomotive and operation information, the alarm protection device dispatches alarm protection tasks to the corresponding underground audible and visual alarms and automatically lowering protective ropes on the corresponding tracks, thus achieving intelligent linkage of alarm protection. Furthermore, the raising of the automatically lowering protective ropes provides physical isolation protection for the vertical track area at the level crossing. Attached Figure Description

[0023] In the description of this invention, it should be understood that the method involves multiple steps and should not be construed as a limitation on the order of the steps. Technical solutions obtained by changing the order of steps when solving the same technical problem are also within the protection scope of this invention.

[0024] Example 1: This embodiment provides a level crossing train approach alarm protection system, including an STP system (Shunting Train Protection System, wireless shunting locomotive signaling and monitoring system), a depot dispatching console, a depot dispatching system, a data storage server, and alarm protection devices. The STP system is located in the station dispatching building, the depot dispatching console is located in the depot dispatching room, and the data storage server is located in the depot machinery room, and they are connected to each other via optical fiber.

[0025] Specifically, station dispatchers input locomotive information for the day's entry and exit from specific tracks within the depot into the STP system based on track occupancy and turnout usage. This locomotive information includes the track entry number, entry time, and track occupancy duration. The STP system then synchronously inputs this locomotive information to the depot's intra-depot dispatching system and alarm protection device via a data storage server. Within the depot's intra-depot dispatching system, based on the locomotive information from the STP system, the dispatcher independently arranges shunting locomotive movement, track switching, and turnaround operations according to track and turnout occupancy. This operation information includes the shunting locomotive entry track number, entry time, and track occupancy duration. In other embodiments, temporary plans can be added according to plan requirements. The depot's intra-depot dispatcher inputs the operation information to the alarm protection device via the data storage server. The alarm protection device performs its protection tasks based on the locomotive information transmitted by the STP system and the operation information transmitted by the depot's intra-depot dispatching system.

[0026] In this embodiment, firewalls are installed between the alarm protection device and the STP system and the vehicle depot's intra-depot dispatching system to prevent mutual interference between the systems.

[0027] Decoders are installed on the side of the firewall closest to the alarm protection device. Information transmission is one-way. The alarm protection device receives data from the STP system and the vehicle depot's intra-depot dispatching system and decodes and analyzes it on its own. The data is not transmitted back.

[0028] Specifically, the alarm protection device includes a server, a power-on magnet, a power-off magnet, signal cables, an automatic lifting and lowering protective rope, an underground audible and visual alarm, and a machine vision system. The server is located in the machine room within the depot. After receiving the operation information transmitted by the depot's dispatching system and the locomotive information transmitted by the STP system, the server automatically counts and dispatches alarm protection tasks to the underground audible and visual alarms and automatic lifting and lowering protective ropes on the corresponding tracks based on the operation information and locomotive information.

[0029] The automatic statistics process involves automatically compiling information on locomotives and track occupancy transmitted from the STP system to the depot's internal dispatching system via the railway's internal network, as well as information on temporary locomotives and track occupancy manually arranged by depot production personnel. This information is then categorized and automatically compiled according to vehicle number, passage time, and route information. Once the statistics are complete, the train number information and train passage time are transmitted to the alarm and protection device. The alarm and protection device then performs its protective operation after confirming that the operational and locomotive information, as well as the information from the on-site equipment, are consistent and accurate.

[0030] The activation magnet is located 50m ahead of the oncoming traffic at the level crossing. It includes a first wheel sensor, a first outdoor antenna, and a first monitoring camera. The first wheel sensor is located 50m ahead of the oncoming traffic, and the first outdoor antenna is located behind it for signal transmission. The first monitoring camera is located outside the track and monitors the operating status of the first wheel sensor and the first outdoor antenna. In this embodiment, the first wheel sensor is a TK-CJ3 model. When the locomotive runs over the first wheel sensor, it triggers the activation magnet to operate. The first outdoor antenna ensures the transmission of activation information. When the locomotive runs over the activation magnet, it automatically opens and enters the working state. The activation magnet uploads the activation information to the server, which sends an activation command to the train number recognition mechanism. The train number recognition mechanism automatically opens and identifies the train number of the approaching train. The first monitoring camera monitors the operation of the activation magnet, thereby reducing false alarms.

[0031] A vehicle number recognition mechanism is installed 30m ahead of the oncoming traffic at the level crossing. The vehicle number recognition mechanism is located behind the start-up magnet and is used to verify whether the oncoming vehicle information is consistent with the locomotive information of the STP system and the operation information of the depot's internal dispatching system. The confirmed information automatically generates a production report for management and maintenance within the depot.

[0032] Specifically, the vehicle number recognition mechanism includes a camera, a column, and transmission cables. The column is installed on the side of the track and is 1.2m high. The camera is installed on the column and takes pictures of the vehicle number information for recognition. In this embodiment, the recognition process is existing technology. For details of the recognition process and algorithm, please refer to the paper "Research and Application of Fully Automated Driving Subway Vehicle Number Recognition Method".

[0033] The shutdown magnet is installed 30m away from the oncoming traffic direction at the level crossing. The shutdown magnet includes a second wheel sensor, a second outdoor antenna, and a second monitoring camera. The second wheel sensor is located 30m away from the oncoming traffic direction, and the second outdoor antenna is located behind the second wheel sensor for signal transmission. The second monitoring camera is located outside the track and is used to monitor the operating status of the second wheel sensor and the second outdoor antenna. In this embodiment, the second wheel sensor is model TK-CJ3. When the locomotive runs over the second wheel sensor, it triggers the shutdown magnet to operate. The second outdoor antenna ensures the transmission of shutdown information of the shutdown magnet. The second monitoring camera monitors the shutdown magnet operation process, thereby reducing false alarms.

[0034] Automatic lifting and lowering protective ropes are installed on both sides of the level crossing and located underground. The automatic lifting and lowering protective ropes include an automatic lifting hydraulic structure, a horizontal pull rope, and a protective cover. The automatic lifting hydraulic structure is located underground, the horizontal pull rope is positioned between the automatic lifting hydraulic structure, and the protective cover is positioned above the automatic lifting hydraulic structure and the horizontal pull rope. When the underground audible and visual alarm is activated, the protective cover opens, and the automatic lifting hydraulic structure connected to the horizontal pull rope automatically rises from the ground, forming a physical isolation and protection for the vertical track area of ​​the level crossing. After the protection is completed, the automatic lifting hydraulic structure automatically lowers, and the horizontal pull rope connected in the middle follows. To ensure the flatness of the level crossing surface and the cleanliness of the pull rope, grooves are excavated in the vertical projection area of ​​the automatic lifting hydraulic structure and the horizontal pull rope at the level crossing. The depth of the grooves ensures that the horizontal pull rope is below the elevation of the level crossing after it falls. Subsequently, the protective cover automatically closes, forming an isolation and protection for the automatic lifting hydraulic structure and the horizontal pull rope.

[0035] The underground audible and visual alarm is installed below ground level at the level crossing. It includes both light and voice alarm components. In this embodiment, the light is a Longwei model, and the voice alarm component is a K50L model. When a wheel runs over the first wheel sensor, the alarm protection device's server receives the incoming vehicle information from the first wheel sensor and sends a command to the underground audible and visual alarm, triggering an audible and visual alarm. When the wheel runs over the second wheel sensor, the alarm protection device's server receives the incoming vehicle information from the second wheel sensor and sends a command to the underground audible and visual alarm, which automatically stops working. Due to the frequent operation and high volume of pedestrian and vehicle traffic at the level crossing, the light and voice alarm components are underground. The installation location of the underground audible and visual alarm requires excavating holes according to the size of the light and voice alarm components. The light and voice alarm components are installed in the holes, and after installation, the surface of the underground audible and visual alarm is aligned with the elevation of the level crossing.

[0036] The machine vision system is set in the protection area of ​​the level crossing. A rectangular protection area is set according to the size of the level crossing. The rectangular protection area is the protection area. In this embodiment, the machine vision system is Hikvision DS-2DC6223IW.

[0037] The machine vision system's camera identifies whether anyone is lingering in the protected area by recognizing their walking behavior. It automatically determines that someone is lingering in the protected area by detecting facial features or movement, thereby triggering an underground sound and light alarm to remind people to leave the protected area as soon as possible.

[0038] In this embodiment, during the process of locomotives entering and leaving the depot, the starting magnet is first crushed, and then the underground audible and visual alarm is activated to remind the workers on the track to leave the level crossing as soon as possible. The machine vision system uses a camera to intelligently detect and determine whether there are any personnel remaining in the protected area of ​​the level crossing. After the determination is completed, the automatic lifting and lowering protective rope rises from the rail surface to 1m. After the locomotives pass through the level crossing and crush the stopping magnet, the machine vision system uses a camera to intelligently detect and determine whether there are any personnel or locomotives remaining in the protected area of ​​the level crossing. After the determination is completed, the automatic lifting and lowering protective rope automatically falls, and the underground audible and visual alarm is deactivated, thus completing the alarm protection operation, and personnel can then pass through.

[0039] Example 2: This embodiment provides a train approach alarm and protection method for level crossings, the steps of which are as follows: S1: The personnel at the station dispatch console input locomotive information for the day’s locomotives entering and leaving specific tracks in the depot based on the track occupancy and turnout usage within the depot. The STP system then synchronously inputs the locomotive information to the depot’s dispatching system and alarm protection devices through the data storage server. S2: The depot dispatcher, based on the locomotive information issued by the STP system, arranges the locomotive routing, track switching, and turnaround operations within the depot according to the track and turnout occupancy status of the depot's dispatching system. The depot dispatcher then inputs the operation information into the alarm protection device's server through the data storage server. S3: The alarm protection device server dispatches alarm protection tasks to the underground sound and light alarms and automatic lifting and lowering protective ropes of the corresponding tracks based on the locomotive information transmitted by the STP system and the operation information transmitted by the depot's intra-section dispatching system. S4: When locomotives and rolling stock run over the starting magnet during their entry and exit from the depot, the underground sound and light alarm will sound and light to remind the workers in the track to leave the level crossing as soon as possible. S5: The machine vision system uses a camera to intelligently detect and determine whether there are any people lingering in the protection area of ​​the level crossing. After the determination is completed, the automatic lifting and lowering protective rope rises from the rail surface to 1m. S6: When the locomotive passes through the level crossing and the rolling shutdown magnet is compacted, the machine vision system uses a camera to intelligently detect and determine whether there are personnel or locomotives staying in the protection area of ​​the level crossing. After the determination is completed, the automatic lifting and lowering protective rope automatically drops, and the buried sound and light alarm is deactivated, thus completing the alarm protection operation, and personnel can then pass through.

[0040] The locomotive information and operation information include the track entry number, track entry time, and track occupation duration. The information transmission is one-way. The alarm protection device receives data from the STP system and the depot's intra-depot dispatching system and decodes and analyzes it itself. The data is not transmitted back.

[0041] Example 3: In this embodiment, there are four maintenance tracks within the depot, numbered as Vehicle 1, Vehicle 2, Vehicle 3, and Vehicle 4, all consistent with the maintenance plan for January 1st. This maintenance plan is formulated based on vehicle operating status and mileage data. Assuming Vehicle A is undergoing maintenance work on track 1 of the depot on January 1st, this work information (including work content, track, and time occupied) has been uploaded to the station dispatch console via the depot's dispatching system. At this time, Vehicle A is already parked on track 1. After a period of time, the station dispatch console receives a receiving instruction to bring Vehicle B to the depot. The station dispatch console then... The dispatching system within the section automatically schedules routes based on the work information uploaded. At this time, turnouts 1, 2, and 3 are not occupied. The station dispatching console can select tracks 2, 3, and 4. Assuming track 3 is selected, the station dispatching console sends locomotive information (including car number, vehicle passage time, track occupancy, etc.) to the STP system. The STP system sends locomotive information to the alarm protection device. The alarm protection device dispatches alarm protection tasks in advance based on the locomotive information sent by the STP system. When car B enters track 3 and runs over the starting magnet, the alarm protection device, which is in a dormant state, is activated to perform protection operations.

[0042] The above examples illustrate the present invention only to aid in understanding it and are not intended to limit the scope of the invention. Those skilled in the art can make various simple deductions, modifications, or substitutions based on the principles of this invention.
