DATA COLLECTION DEVICE, SIGNAL GENERATION POSITION IDENTIFICATION SYSTEM, DATA COLLECTION METHOD, SIGNAL GENERATION POSITION IDENTIFICATION METHOD, AND PROGRAM

WIPO Patent Application WO/2020/226069

A1

This data collection device comprises: a reference signal reception unit that receives a reference signal which indicates a first time clocked by an external device and transmitted from the external device at a first time interval; a time signal generation unit that clocks time at a second time interval and generates a time signal indicating a second time thus clocked; a parameter generation unit that generates a parameter value on the basis of the first time indicated by the reference signal and the second time based on a time signal generated at the point in time when the reference signal was received; a signal reception unit that receives an analog signal indicating the signal waveform of an observed signal; a sampling unit that samples the received analog signal at the second time interval and generates sampling data; and a data processing unit that performs an interpolation process on the sampling data on the basis of the parameter value.
