A method and system for dynamic tracking of locomotive/rail car based on multi-station yard

Abstract

The present invention belongs to the locomotive / rail car work protection or control technology field, in particular relates to a multi-station yards-based locomotive / rail car dynamic tracking method and system. The method comprises the steps of using an MA server to position the positions of the locomotives / rail cars to the station yard concrete elements accurately, and sending the concrete locomotive / rail car position information to a querying server; using the querying server to screen and tidy the multi-station yard data and the locomotive / rail car position information sent by the MA server, and sending to a client; using the client to draw a station yard diagram according to the loaded station yard basic data, and using the client to real-timely receive and load the locomotive / rail carposition information and draw the locomotives / rail cars on the station yard diagram, thereby real-timely and dynamically tracking the station yard locomotives / rail cars. According to the application,the locomotive / rail car high-precision positioning, the locomotive / rail car multi-station yard real-time and dynamic tracking and the multi-station yard information automatic splicing can be realized.

Description

technical field [0001] The invention belongs to the technical field of locomotive / rail car operation protection or control, and in particular relates to a multi-station-based locomotive / rail car dynamic tracking method and system. Background technique [0002] Current Locomotive / Rail Station Yard Tracking Method: [0003] Manually track and manage locomotives / railcars. If the location of the locomotive / rail car is marked on the station map on the wall, the dispatcher will contact the shunter through the walkie-talkie, and when he knows that the locomotive / rail car has completed the dispatching order and moved to a new track or maintenance depot, immediately Move the locomotive / railcar markers on the station yard map to the corresponding lanes. [0004] The locomotive / rail car automatic tracking system based on computer interlocking is applicable to all locomotive depots that have used computer interlocking equipment. System structure see figure 1 . The system is mainly ...

AI Technical Summary

Problems solved by technology

[0006] Problems in the locomotive / rail car automatic tracking system based on computer interlocking: (1) The system judges the location of the locomotive / rail car based on the trajectory of the locomotive / rail car and the status of the station section, and the location of the locomotive / rail car is not accurate enough. It can only locate the section where the locomotive / rail car is located, and cannot give a specific and precise location

(2) The position of the locomotive / rail car depends on the trajectory of the locomotive / rail car and the state changes of the station elements. Once a network failure occurs, the position and running direction of the locomotive / rail car cannot be determined immediately after the network is restored

(3) Unable to achieve cross-site tracking

[0007] In addition, the current locomotive / rail car tracking method is mostly based on a single station. Compared with the multi-station mode, the single-station mode has the following disadvantages: (1) It is inconvenient for users to use and can only monitor other station information by switching stations ;(2) The monitoring information is single, and only the current station can be monitored at the same time; (3) Real-time tracking of cross-station locomotives / railcars cannot be realized; (4) It is impossible to perform intuitive real-time tracking of all locomotives / railcars within the jurisdiction show
