ATP/ATC SUBSYSTEM TESTING AND VALIDATION USING A HIL TEST RIG
Automatic Train Protection (ATP) systems ensure that trains comply with speed restrictions and prevents against passing red signals. The system is designed in order to automatically act to slow or stop the train when the train exceeds speed limits or pass signals at danger. The safety and reliability of the system is crucial for the safety and efficiency of the railway system. A correct estimation of distance to target and actual velocity is fundamental to evaluate residual braking resources, in terms of available deceleration, in order to reach the targets at the required speeds. The so-called odometry algorithm is the ATP subsystem devoted to train speed and traveled distance evaluation and it is composed by a series of sensors and a software procedure that acquires and manages the information from the sensors. Odometry estimation accuracy has a great influence on the ATP system behavior and must be carefully designed and verified. This paper focuses on the odometry device developed for the Italian ATP system (SCMT) and the criteria used to design the tests and the architecture of the test rig presented. The paper will summarize the results obtained from the testing activities and give an estimation of the odometry subsystem performance.
