Description

Technical Field

[0001] The present application belongs to the field of video technology, and specifically relates to a real-time monitoring method and system for station shunting operations. Background Art

[0002] At present, the station yard monitoring video system is generally established step by step by each type of work and department, and a unified monitoring management platform is established later. In actual use, the monitoring is based on different business scenarios, and generally shoots the same area for a long time at a fixed angle and focal length. The station yard shunting operation is a large-scale business scenario that runs through the entire station yard. If you want to track and replay a shunting operation, you need to obtain the locomotive's running trajectory based on the locomotive operation time and operation plan, and then filter the monitoring list based on the area where the locomotive passes and the existing station yard monitoring installation location. Then, obtain the monitoring video within the time period when the locomotive passes on the monitoring management platform and play them separately to view the complete information of this shunting operation from all angles.

[0003] It can be seen that the linkage ability between monitoring resources in the existing technology is weak, and the video tracking of station shunting operations can only be achieved by manual tracking of single-point monitoring, which is inefficient and incomplete.

[0018] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0019] The embodiments of the present application provide a real-time monitoring method and system for station shunting operations, including the construction of a visual dispatching platform for the station, the construction of a Beidou enhanced base station in the station, the installation of on-board high-precision positioning equipment on the shunting locomotive, and the construction of a geographical scene based on a high-precision electronic map of the station. By collecting basic information on station monitoring, monitoring resources are divided into different levels according to business usage scenarios and types. During the shunting operation, different monitoring linkage plans are activated according to the position of the locomotive and the importance of the operation, and the designated preset positions of the relevant cameras are called to realize video linkage tracking of the shunting operation. During the operation, the progress of the operation, the start time of the monitoring resource call and other information are recorded throughout the operation to facilitate the complete playback of the historical shunting operations.

[0020] In conjunction with the accompanying drawings, a real-time monitoring method for station shunting operations provided by an embodiment of the present application is described in detail through specific embodiments and application scenarios.

[0021] like Figure 1 As shown, it is a flow chart of a real-time monitoring method for station shunting operations provided by an embodiment of the present application, and the method includes the following steps:

[0022] Step 101, obtaining real-time position information of a shunting locomotive in a station yard, and determining a grid area where the shunting locomotive is located according to the real-time position information.

[0023] In this embodiment, the station field can be divided into multiple grid areas according to the station field design drawing, station field usage and monitoring resource points.

[0024] Furthermore, monitoring information can also be collected and a monitoring resource information library can be established based on the monitoring information. The monitoring information includes the installation location, type, installation fixing angle, installation height, manufacturer, type, visible distance and visible angle of all monitoring resources in the station. According to the specific location of the monitoring resources in the station, multiple monitoring preset positions for close-up, long-range and different coverage areas are configured for the monitoring resources, and the monitoring preset positions are associated with the grid areas in the station.

[0025] Step 102: retrieve the associated monitoring resources according to the gridded area, and adjust the shooting area of ​​the monitoring resources by sending the associated monitoring preset position calling instructions to the monitoring resources.

[0026] Specifically, the associated monitoring preset positions may be retrieved according to the gridded area, and the monitoring resources corresponding to the monitoring preset positions may be determined; and the shooting area of ​​the monitoring resources may be adjusted by issuing monitoring preset position calling instructions to the monitoring resources.

[0027] Step 103, split screen displays the real-time position of the shunting locomotive, linked monitoring resources, ongoing operation information, and multi-channel linked real-time video.

[0028] In this embodiment, the operation start time of the shunting operation, the locomotive operation information, the driving track and the start time of the associated monitoring resources can be stored.

[0029] The embodiments of the present application can achieve real-time video linkage tracking of shunting operations by acquiring the position information of shunting locomotives in real time, dynamically associating the station area and monitoring resources, and controlling the monitoring shooting area, thereby improving the linkage capability between monitoring resources.

[0030] In an embodiment of the present application, a real-time monitoring method and system for station yard shunting operations can be used to achieve real-time video tracking of the station yard shunting operation process and panoramic playback of historical shunting operation videos.

[0031] Specifically, through aerial survey, centimeter-level high-precision digital orthophoto images of the station are collected, and vector data information such as tracks, switches, switches, signals, buildings, etc. are extracted based on the images. The station is divided into grid areas according to the station design drawings, station purposes, monitoring resource points and other information, thereby establishing a station geographic visualization system module.

[0032] Furthermore, the station monitoring linkage system module is connected to the station monitoring management platform to re-collect information such as monitoring installation location, type, installation angle, installation height, manufacturer, type, visual distance, and visual angle to establish a monitoring resource information library. Multiple virtual tags are added to monitoring resources to establish associations with station areas, uses, and importance, which facilitates quick retrieval and positioning. The operable monitoring resources in the system are configured with multiple preset positions for near-view, far-view, and different coverage areas according to specific locations, and are associated with the station grid area. The monitoring resources are associated with each other through preset positions to establish coverage relationships.

[0033] In this embodiment, by building a Beidou ground-based augmentation station, centimeter-level precision real-time differential data services are provided for locomotive positioning equipment, etc. The shunting locomotive is equipped with a high-precision Beidou positioning device on board, which obtains differential data from the Beidou enhanced base station in real time, and reports centimeter-level positioning data to the center more than 5 times per second. Accordingly, during the shunting operation, according to the real-time position of the locomotive in the station, the grid area information is obtained, the associated monitoring resources are dynamically retrieved, the associated monitoring preset position call instructions are issued, and the monitoring shooting area is adjusted. The location of the monitoring resources in the station is displayed in the geographical scene, and the locomotive position, associated monitoring resources, etc. are updated in real time. The shunting operation is tracked in real time, and the system is displayed in a split screen. One side displays the real-time position of the locomotive, the linked monitoring resources, and the ongoing operation information, and the other side displays multi-channel linked real-time video.

[0034] In addition, the system can also store information such as the start time of the shunting operation, locomotive operation information, driving trajectory, and the start time of the associated monitoring resources. Accordingly, when the shunting operation is played back historically, it can be displayed in split screens. On one side, the historical trajectory, locomotive operation status, management monitoring resource status, and operation plan execution status are drawn in the geographical scene, and the other side displays the associated monitoring historical video at the operation time point, including the monitoring list, monitoring start time, duration, and other information, which can be dragged and paused at any time point of the operation.

[0035] The embodiment of the present application establishes a geographic visualization system by collecting and improving basic monitoring information and high-precision electronic maps of the station, which can intuitively display the station layout and monitoring resource information, facilitate the maintenance of monitoring resources, and improve the linkage capability in shunting operations. Satellite positioning technology is used to obtain locomotive position information in real time, display the locomotive position in real time, dynamically associate the locomotive with the station area, retrieve monitoring resources, control the monitoring shooting area, and realize real-time video linkage tracking of shunting operations and complete playback of shunting history operations.

[0039] Specifically, the retrieval module 220 is specifically used to retrieve the associated monitoring preset positions according to the gridded area, and determine the monitoring resources corresponding to the monitoring preset positions; and adjust the shooting area of ​​the monitoring resources by issuing monitoring preset position calling instructions to the monitoring resources.

[0040] The display module 230 is used to display the real-time position of the shunting locomotive, the linked monitoring resources, the ongoing operation information, and the multi-channel linked real-time video in a split screen.

[0044] The division module is used to divide the station into multiple grid areas according to the station design drawing, station purpose and monitoring resource points.

[0045] The storage module is used to store the start time of the shunting operation, locomotive operation information, driving trajectory and the start time of the associated monitoring resources.

[0046] The embodiments of the present application can achieve real-time video linkage tracking of shunting operations by acquiring the position information of shunting locomotives in real time, dynamically associating the station area and monitoring resources, and controlling the monitoring shooting area, thereby improving the linkage capability between monitoring resources.
