The GPS application for the control of the rail vehicle

Abstract

The paper deals with the control methods for routing optimization of bogie in rail track (i.e. rail channel) with the usage of GPS. Consequently the GPS information is used for determining of position and the curve radius track. These parameters are necessary for the tested control methods. For this research stage the experimental rail vehicle powered by the traction battery is also utilized. This vehicle has one bogie with independent rotating wheels driven by PMSM drives. At the present the testing control methods is always implemented to the superset control system of the experimental rail vehicle. The traction requirements and curve radius track have the affect to an algorithm of this control method. These algorithms are verified and corrected according to traction and driving characteristics. The aim of these research activities is achieving of wear reduction of wheels and rails during a run of tram vehicles without solid axles of bogies and increasing of running comfort.

Research on the Applicability of Vibration Signals for Real-Time Train and Track Condition Monitoring

“…The measurement system and methodology allow control and registration of the current position of a train, with a ca. 1 s time interval (GPS module) [ 23 , 24 ]. The system also enables simultaneous registration 10 times for each 1 s acceleration of train (MEMs module).…”

“…Vibration research in rail transport is most often related to the phenomenon of wheel-rail contact or impact on buildings in the vicinity of the tracks [ 20 , 21 , 22 , 23 ]. On the other hand, a very frequently studied problem in rail transport is the control and management of vehicle traffic [ 24 , 25 , 26 , 27 ]. Thus, vibroacoustic methods should be considered as a support for monitoring systems in the field of transportation due to their usefulness in evaluating human exposure and monitoring the technical state of the transport system.…”
