Abstract

The data acquisition unit acquires data in correspondence with each dimensional axis and the time axis. The mode setting unit makes setting and clearing of a dimensionality investigation mode. In the dimensionality investigation mode, the axis-determinative variation-rate calculation unit calculates axial data variation rates. The axis determination unit determines whether or not the axial data variation rate corresponding to each axis is low. The objective-axis setting unit sets each axis as an objective axis when the axial data variation rate corresponding to the axis is determined to be high. While the dimensionality investigation mode is cleared, the recording-determinative variation-rate calculation unit calculates axial data variation rates. The recording determination unit determines, on the basis of the axial data variation rate, whether to record the acquired data. The recording unit does not record the data when the data is determined not to be recorded.

Dependent claims

A computer-readable recording medium storing a data recording program for recording data which varies with time in a space constituted by dimensional axes, the data recording program, when executed by a computer, causes the computer to function as:

a data acquisition unit which acquires data varying with displacement in the direction of each of the dimensional axes and time indicated by a time axis, in correspondence with the time axis and each of the dimensional axes;
a mode setting unit which sets said computer in a dimensionality investigation mode for determining, on the basis of magnitudes of variations of said data in axial directions, one or more objective axes to be one or more objects of investigation as to dimensionality, and clears setting of the dimensionality investigation mode;
an axis-determinative variation-rate calculation unit which calculates, on the basis of the data acquired by the data acquisition unit, an axial data variation rate indicating a rate of variation in the acquired data corresponding to displacement in a direction of each of the dimensional axes and the time axis, while the computer is in the dimensionality investigation mode;
an axis determination unit which determines, on the basis of the axial data variation rate calculated by the axis-determinative variation-rate calculation unit, whether or not the axial data variation rate corresponding to each of the dimensional axes and the time axis is low;
an objective-axis setting unit which sets one or more of the dimensional axes and the time axis as one or more objective axes when one or more axial data variation rates corresponding to the one or more of the dimensional axes and the time axis are determined by said axis determination unit to be high, and does not set the other of the dimensional axes and the time axis as one or more objective axes when one or more axial data variation rates corresponding to the other of the dimensional axes and the time axis are determined by the axis determination unit not to be high;
a recording-determinative variation-rate calculation unit which calculates, on the basis of the data acquired by the data acquisition unit, an axial data variation rate indicating a rate of variation in the acquired data corresponding to displacement in a direction of each of the one or more objective axes which are set by the objective-axis setting unit, while the computer is out of the dimensionality investigation mode;
a recording determination unit which determines, on the basis of the axial data variation rate calculated by the recording-determinative variation-rate calculation unit, whether to record said data;
and
a recording unit which records in a data table the data when the recording determination unit determines to record the data, and does not record in the data table the data corresponding to the data when the recording determination unit determines not to record the data.
