PROBLEM TO BE SOLVED: To propose a creation method of teacher data capable of improving ground-determining accuracy, by collecting data capable of a waveform analysis of a frequency band corresponding to a natural ground situation.SOLUTION: The creation method of the teacher data used when determining whether or not an excavator reaches the target ground, comprises waveform data acquiring work S1 for acquiring excavation waveform data of a physical quantity correlated to an operation state of the excavator in the ground equal to the target ground by 2.m pieces in a sampling frequency S by excavating a survey boring hole in the geological-already-known ground by the excavator and teacher data creation work S2 for creating teacher data of a frequency band S/(2.2) by analyzing (m) pieces among the excavation waveform data of 2.m pieces, and in the teacher data creation work S2, the teacher data is created by using data of k+2.p-th (p=1 to m-1) from a (k)-th among the excavation waveform data of 2.m pieces. |
