Infinity-Case Based on Train Carried ATP Testing System

The train carried ATP (Automatic Train Protection) system is the main aspect of the ATC (Automatic Train Control) system. While acquiring MA (Moving Authority) information from track side ATP, a train carried ATP analyzes and outputs the speed restriction in real time. When the train speed approaches the speed restriction, ATP will alarm to the driver when the train is over speed. ATP will then brake the train in an emergency. ATP pl ays such a vital role that it must be fully tested before put into service. A new testing method based on Infinity-Case Methodology and Virtual Instrumentation is proposed to meet test requirements under various conditions. Simulation and field tests imply that the test system is efficient, easy to use and can meet all the test requirements.
