Abstract: This article used the B/S architecture based on JavaEE and the high performance and high concurrency relational database to construct the quality mutual control system between the vehicle operation workshop and the maintenance workshop as well as their own workshops. The system can give early warning to the next operation link for the vehicle fault found in the through train. Through forward early warning and backward mutual control, the vehicle operation and maintenance quality can be tracked in an all-round way to ensure the safety of vehicle operation.
