Abstract
Według sposobu, sygnał akustyczny generowany przez poruszające się pojazdy i sygnał magnetyczny otoczenia wynikający z zaburzeń pola magnetycznego ziemi, rejestruje się przez mikrofon (1) i magnetometr (2), rozmieszczone w pobliżu toru jazdy obiektu. Dla danego toru pomiarowego analizuje się szybkość zmian poziomu natężenia dźwięku i poziomu zmian zaburzeń pola magnetycznego, przy czym podczas nagłego wzrostu sygnału ciśnienia akustycznego przeprowadza się analizę sygnału magnetycznego pod kątem identyfikacji zjawisk magneto-mechanicznych i wykrywa zaburzenia magnetomechaniczne wskazujące na zaistnienie zdarzenia drogowego typu zderzenie.According to the method, the acoustic signal generated by moving vehicles and the ambient magnetic signal resulting from disturbances in the earth's magnetic field are recorded by a microphone (1) and a magnetometer (2) located near the object's track. For a given measurement track, the rate of change in the sound intensity level and the level of change in the magnetic field are analyzed, while during a sudden increase in the sound pressure signal, an analysis of the magnetic signal is carried out to identify magneto-mechanical phenomena and magnetomechanical disturbances indicating a collision-type traffic event are detected.
