PROBLEM TO BE SOLVED: To accurately correct a measurement time even at a place where communication with the outside is difficult, using a plurality of measurement terminals mounted with a low-accuracy oscillator that is inexpensive and consumes less power.SOLUTION: A measurement time correction system 500 comprising a plurality of measuring terminals and a management server capable of obtaining measurement data by the measuring terminals, comprises: an excitation control unit 140a that controls generation of a flag signal to synchronize measurement data; a signal acquisition unit 100a that acquires the flag signal at a measuring terminal side; a deviation amount calculation unit 140c that calculates the amount of deviation per unit time of another measuring terminal to one measuring terminal among the plurality of measuring terminals on the basis of the acquisition times of a plurality of flag signals received from the plurality of measuring terminals; and a correction unit 140d for correcting the measurement data on the basis of the calculated amount of deviation.SELECTED DRAWING: Figure 27 |
