Abstract: According to an embodiment, a detection system includes a plurality of sensor nodes and a sensor module. The plurality of sensor nodes detects sound waves generated from a prestressed concrete and converts the detected sound waves into detection signals. The sensor module is connected to the plurality of sensor nodes and receives the detection signals. The plurality of sensor nodes includes the sensor nodes in an operating state and the sensor nodes in a dormant state in which power consumption is held down as compared to the operating state. When magnitude of the detection signals is equal to or greater than a first threshold value, the sensor module switches the sensor node in the dormant state to the operating state.

Abstract: A measurement device and a measurement method capable of measuring a depth of a damage source in a structure having a thickness of a predetermined value or more. According to an embodiment, a measurement device includes a first detector and a signal processing device. The first detector selectively detects surface waves that are excited when first elastic waves generated inside a structure formed of a solid material have reached a surface of the structure. The information processing device obtains information about a depth of a source of the first elastic waves within the structure on the basis of information of at least one of an amplitude and a time of arrival of the surface waves detected by the first detector.
