Opis:
This article presents the current problems with measuring distance in goods wagons. The main problem where goods wagons are concerned is their lack of power supply. Owing to this, a distance-measuring system is hard to install. Meanwhile, the measurement of distance travelled and the service processes dependent on this measurement are becoming more and more important. Moreover, the railway accident in Viareggio on June 29, 2009 has resulted in increased interest in determining the accurate mileage of a wagon or, to be exact, of a wheelset. One has to realise, that a goods wagon is actually a combination of numerous elements (such as the body, the underframe, the carriage, the wheelsets, etc.) that can differ in mileage and can be exchanged between different wagons. This makes it necessary to register not only the mileage of the whole wagon, but also, at a minimum, of the carriage. This article is an attempt at outlining the current state of this issue.

Opis:
The article presents review of methods and devices for track measurement of rail vehicles in aspect of diagnostics and safety of use. Currently used solutions do not enable effective "on-line" measurement of mileage by wheelsets and vehicles' axles in rail vehicles without electric power supply such as goods wagons and cisterns. Those solutions have limited functionality and have to use additional power supply (accumulators, generators, etc.) which significantly increase exploitation costs. A telemetric system for monitoring of wheelsets' mileage as well as of their bearing temperature, based on original solution of odometer installed on the set's grease-box, was suggested in the research. The odometer is powered from an independent source of energy generated through magnetic induction by coil and neodymium magnets. Reading of collected data is done with the help of a PDA equipped with an RFID reader as well as wired and wireless interfaces for data transmission to telemetric system and GPS.
