Abstract
The magnetic detection system 100 is provided with a magnetic sensor 1, a storage unit 5, a first determination unit 42 for outputting whether or not the magnetic body 90 has passed as a first determination result 20, a second determination unit 43 for outputting whether or not the magnetic body has passed as a second determination result 21, a display unit 6 for displaying (notifying) the first determination result and the second determination result. The second determination unit is configured to have higher determination accuracy than the first determination unit.
Claims8
A magnetic detection system comprising:
- a magnetic sensor configured to be installed underwater to acquire a time-series magnetic signal;
- a storage unit configured to store the time-series magnetic signal acquired by the magnetic sensor;
- a signal waveform generation unit configured to generate a signal waveform by delimiting the time-series magnetic signal by a prescribed time,
- a first determination unit configured to output whether or not a magnetic body has passed as a first determination result based on the time-series magnetic signal of the magnetic sensor;
- a second determination unit configured to output whether or not the magnetic body has passed as a second determination result based on the time-series magnetic signal of the magnetic sensor after an output of the first determination result by the first determination unit;
- and
- a notification unit configured to output the first determination result and the second determination result,
- wherein the second determination unit is configured to have higher determination accuracy than the first determination unit,
- wherein the first determination unit is configured to sequentially output the first determination result based on whether or not at least a part of a shape of the signal waveform is a predetermined shape after the prescribed time has elapsed, and
- wherein the second determination unit is configured to output the second determination result based on an entire waveform of the signal waveform after the prescribed time has elapsed.
