Problems solved by technology

This method of remote expert support requires consistency between remote technical simulation analysis and on-site data, and requires effective technical communication between remote experts and on-site technicians. However, the actual situation is that there is often a large gap between the remote technical analysis environment and the actual situation on site. The difference between the remote technical analysis and the actual vehicle situation is usually not satisfied, and the efficiency of problem solving is not high due to the need for repeated problem communication between experts and on-site technicians

Abstract

The invention discloses a fault location method and system based on a vehicle state BIM model, comprising: establishing a vehicle state BIM model; collecting vehicle bus data in real time, and parsing the collected data into condition information data and state information data; The vehicle state BIM model and the analyzed condition information data generate a standard state information file representing each signal state in the normal state of the vehicle; compare the analyzed state information data with the standard state information file to obtain the fault location result. The present invention uses the vehicle state BIM model to match the condition information of the faulty vehicle to obtain standard state information, and then the field technicians compare the standard state information with the faulty vehicle state information to obtain differential information to assist fault location analysis; Technical requirements for technicians, while improving maintenance efficiency.

Description

Technical field [0001] The present invention relates to the field of rail vehicle fault location technology, in particular to a fault location method and system based on the vehicle state BIM model. Background [0002] The statements in this section merely provide background technical information related to the present invention and do not necessarily constitute prior art.
