  • Patent number: 9921188
    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.
