Description

Technical Field

[0001] This utility model relates to the field of rail transit operation and maintenance simulation training technology, and in particular to a CBTC on-board equipment intelligent maintenance cockpit based on virtual reality. Background Technology

[0002] Urban rail transit is a vital pillar of modern urban transportation, and its efficient and safe operation relies on advanced signal control systems. Communications-Based Train Control (CBTC) has become the core technology for rail transit signal control. However, due to its high integration and complexity, CBTC onboard equipment faces challenges in operation and maintenance, including high technical barriers, high training costs, and high failure risks.

[0003] Currently, CBTC on-board equipment maintenance training mainly relies on traditional classroom lectures and low-fidelity simulation platforms, resulting in insufficient practical depth and poor interactivity. Trainees typically gain limited experience through theoretical learning or simple operations, making it difficult to fully grasp the equipment's operating logic and methods for handling complex faults. This training model has significant limitations in terms of practicality and intuitiveness, failing to meet the demands of intelligent maintenance for efficiency and accuracy.

[0004] With the rapid development of virtual reality (VR) technology, using VR to build immersive virtual scenes to realistically simulate equipment operating status and fault scenarios, and to provide trainees with an interactive experience that closely resembles practical operation, has become an effective way to improve the effectiveness of operation and maintenance training.

[0005] Therefore, it is necessary to develop a virtual reality-based intelligent maintenance cockpit for CBTC in-vehicle equipment to address the aforementioned shortcomings. Utility Model Content
