Description

Technical Field

[0001] This utility model relates to the technical field of railway shunting operation equipment, specifically to a railway shunting precision positioning system. Background Technology

[0002] With the rapid development of railway transportation, the requirements for safety and efficiency in shunting operations are increasing. Although there has been some investment in shunting equipment, it is still difficult to meet the high-precision positioning and real-time control needs of shunting operations.

[0003] Currently, shunting personnel primarily obtain shunting plans and record the entire process using shunting equipment. After completion, the video is uploaded to the intranet storage via a data acquisition device. Management personnel then review the executed shunting plan video and, in conjunction with the shunting audio recordings, check for suspected violations. This method is not only inefficient but also ineffective in preventing accidents through post-event checks for violations. While existing shunting auxiliary equipment provides basic operational support, it lacks real-time, precise positioning and control functions, failing to meet the urgent safety and efficiency requirements of modern railway shunting operations.

[0004] The existing shunting auxiliary equipment mainly suffers from the following problems: Insufficient positioning accuracy: Traditional positioning systems can only achieve an accuracy of 5 to 20 meters, which cannot meet the requirements for precise vehicle connection and safe operation in shunting yards where the track spacing is less than 5 meters or even smaller.

[0005] Lack of real-time monitoring and early warning functions: Existing equipment cannot monitor and warn of shunting operations in real time, making it difficult to detect and deal with potential risks in time before accidents occur.

[0006] Limited data processing and transmission capabilities: The existing system's data processing and transmission lacks real-time performance and stability, making it difficult to meet the needs of efficient transmission and processing of large amounts of data in shunting operations.

[0007] Inadequate work process management: The existing equipment does not adequately manage the shunting operation process and lacks real-time tracking and optimization functions for the execution of work plans.

[0008] RTK technology is currently used by train inspectors and in engineering surveying, but its application in train dispatching, especially in train dispatching in confined spaces, is still rarely heard of. Utility Model Content
