Title:
DETECTION SYSTEM AND DETECTION METHOD
Document Type and Number:
Japanese Patent JP2018063268
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To detect breaking while suppressing power consumption.SOLUTION: A detection system comprises: a plurality of sensor nodes; and a sensor module. Each of the plurality of sensor nodes detects a sound wave generated from pre-stressed concrete and converts the sound wave detected into a detection signal. The sensor module is connected to the plurality of sensor nodes and receives the detection signal. The plurality of sensor nodes includes the sensor nodes in an operation state and the sensor nodes in a resting state where power consumption is more suppressed than that in the operation state. The sensor module brings the sensor nodes in the resting state into the operation state when a magnitude of the detection signal is equal to a first threshold value or more.SELECTED DRAWING: Figure 5
