Telemetric system for track measurement in rails vehicles without electric power supply

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.
