ASSESSMENT OF FUNCTIONAL SAFETY OF DETECTION OF VIBROACOUSTIC SIGNAL FROM ARRIVING TRAIN WITH ENERGY SENSOR
Annotation
Functional safety of detection of a vibroacoustic signal from arriving train with energy detector is investigated. The lower value of detectability level is derived from a proposed false alarm probability. Sufficiency of developed method for detection of arriving train in the case of long-welded rails is demonstrated.
