Device for localizing traffic accidents, especially involving road vehicles, has vibration sensors connected to signal acquisition unit using common time signal to synchronize measurements on different sensors, downstream processing units

摘要

The device has several vibration sensors (5) for detecting mechanical/acoustic vibration signals (S) emanating from an accident location (4) and a signal processing system (3,6-9) for determining the accident location through transition time measurement. Each vibration sensor is connected to a signal acquisition unit (6) that uses a common time signal to synchronize the measurements carried out on different sensors Downstream processing units (3,7) process vibration patterns (EZ) with time stamps (ZS) generated from the common time signal.
