<p>PROBLEM TO BE SOLVED: To provide a magnetic measuring system which can more accurately obtain a time of day when a magnetic substance relatively moving comes closest to a magnetic sensor.SOLUTION: A magnetic amount of a magnetic substance relatively moving near a magnetic sensor is taken in to the magnetic sensor in a prescribed cycle and stored to a storage section (ST 1 to ST 7), a maximum value of the magnetic amount and its time of day are extracted from the stored magnetic data (ST 8), the obtained maximum value and data number around the time of day are extracted (ST 9), and the extracted data are used to perform interpolation processing (ST 10), a maximum value and its time of day are obtained with respect to the data obtained by the interpolation processing (ST 11), and the obtained time of day is outputted as a most proximate time of day (ST 12).</p> |
