Abstract

Since a data acquisition condition setting unit can select a data acquisition start/end trigger, a sampling period of data, and a type of acquired data, a waveform display device, which has a function of allowing only necessary data to be acquired by allowing a plurality of data acquisition conditions to be set with respect to one data acquisition, can set these conditions from a screen of a data acquisition condition setting. When data needs to be acquired according to a plurality of different conditions, a plurality of types of necessary data acquisition conditions is set to set different data acquisition condition names. When a plurality of data acquisition conditions is set by acquiring data once, a multi-data acquisition condition setting unit can set necessary data acquisition conditions using a screen of a multi-data acquisition condition setting. When the data acquisition conditions are set by the multi-data acquisition condition setting unit, data acquisition condition setting names set by the data acquisition condition setting unit are input.

First claim

1 . A waveform display device connected to a numerical controller controlling a driving axis of a machine tool, the waveform display device having a function of acquiring data of a physical quantity related to the driving axis and displaying the data of the physical quantity as a waveform, the waveform display device comprising:
a physical quantity data acquisition unit for acquiring the data of the physical quantity related to the driving axis from the numerical controller; a physical quantity data acquisition condition setting unit capable of setting a plurality of acquisition conditions including at least a type of the data of the physical quantity, a condition of starting and ending acquisition of the data of the physical quantity, and a sampling period for acquiring the data of the physical quantity to extract data from the data of the physical quantity acquired by the physical quantity data acquisition unit; a physical quantity data extraction unit for extracting data of a physical quantity satisfying the conditions set by the physical quantity data acquisition condition setting unit from the data of the physical quantity related to the driving axis acquired by the physical quantity data acquisition unit; a storage unit for storing the data of the physical quantity extracted by the physical quantity data extraction unit; and a display unit for displaying the data of the physical quantity extracted by the physical quantity data extraction unit as a waveform.

2 . The waveform display device according to claim 1 , wherein the physical quantity data extraction unit acquires the data of the physical quantity in parallel based on one or more conditions among the plurality of conditions set by the physical quantity data acquisition condition setting unit.
