A VR-based rail vehicle electrical intelligent maintenance support system and method

Abstract

The invention relates to a VR-based electrical intelligent maintenance support system for rail vehicles, including: a fault database: respectively connected to a fault analysis module, a VR fault database, and an intelligent detection terminal in a vehicle control system for receiving and storing vehicle fault information in real time , and transmit the vehicle fault information to the fault analysis module and VR fault library in real time; fault analysis module: connected to the VR display module, used to calculate possible fault points and sort according to the vehicle fault information, and send the sorting results to the VR display Module; VR fault library: connected to the VR display module, used to obtain the 3D VR model of the fault point of the possible fault point according to the vehicle fault information, and send the 3D VR model of the fault point to the VR display module; VR display module: used to call the 3D fault point VR model, and according to the sorting of possible fault points, the three-dimensional VR model of fault points is displayed in sequence. Compared with the prior art, the present invention has the advantages of improving maintenance efficiency and correct rate.

Description

technical field [0001] The invention relates to the technical field of rail vehicle intelligent maintenance support, in particular to a VR-based rail vehicle electrical intelligent maintenance support system and method. Background technique [0002] Urban rail transit is the backbone of the modern urban public passenger transport system, which better solves the growing contradiction between supply and demand in large and medium-sized cities, and meets the requirements of urbanization. However, online faults of urban rail transit vehicles are inevitable during operation. How to efficiently repair and eliminate faults, and make the vehicles return to operation quickly is an urgent need for urban rail transit operations under the condition of large passenger flow. [0003] At present, most of the online faults are electrical faults of the vehicle control system. When an urban rail vehicle has an online electrical fault, it is often necessary for the staff to screen the vehicle ...

AI Technical Summary

Problems solved by technology

[0003] At present, most of the online faults are electrical faults of the vehicle control system. When an urban rail vehicle has an online electrical fault, it is often necessary for the staff to screen the vehicle type and analyze the specific model according to the circuit schematic diagram to determine the troubleshooting content. According to the circuit schematic diagram and wiring diagram, the electrical components and wiring of the vehicle are checked one by one. The maintenance process takes a lot of time and energy. At the same time, this puts forward higher requirements for technicians. They must be familiar with each component of the vehicle. part, but also have a certain professional technical ability, and the maintenance efficiency and correctness are greatly affected
