System for monitoring integrity of running gears of rail vehicles during driving, has impact sound sensors attached at bogie of rail vehicle and provided with frequency analysis unit and warning unit

摘要

The system has impact sound sensors (1) attached at a bogie (3) of a rail vehicle and provided with a frequency analysis unit and a warning unit. The impact sound sensors are connected one below the other and/or with a central computing unit by a signal line i.e. bus. The impact sound sensors comprise an electronic interface to the bus, and an information-technical interface for information-technical communication with other impact sound sensors and/or an evaluation program. The information-technical interface comprises an identification-number of the sensors and a measuring value. The bus is formed as a Process Field Busor a time division multiplexed bus.
