VOBC Data Storage and Online Diagnosing System Based on Data Cloud Due to the inaccessibility to VOBC (Vehicle Onboard Controller) diagnosing data, urban railway transit operation suffers from transient failures and long time failures during operation time. This essay put forward the idea of a real time diagnosing data storage and cloud sharing system, to collect, store and sharing them, thus reproduce the transient failures for debugging, and proved a quick and effective solution to failures during operation time from a distance.
