Abstract
According to one embodiment, a detection system is provided that detects a state of a structure consisting of a first member that supports a traveling surface along which a vehicle travels from downward; a second member provided on an opposite side of the traveling surface with respect to the first member; and a welded portion that is provided along an end of the second member facing the first member and fixes the first member and the second member. The detection system includes: a first sensor group including first AE sensors; a second sensor group including second AE sensors; and a position orientator that performs separately a first determination that determines a generation source position of elastic waves based on the detection results of the first AE sensors and a second determination that determines the generation source position of elastic waves based on the detection results of the second AE sensors.
