Description

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a measurement method for processing data measured using a measurement device such as a voltage / ammeter connected to a sensor.
[Prior art]
Conventionally, measurement software operating on operation software such as MS-Windows (registered trademark) fetches a plurality of data measured at predetermined sampling times from a measurement device such as a voltage / ammeter connected to a sensor. The captured data was displayed on software and saved in an arbitrary file format along with time information. Furthermore, in order to perform analysis using a plurality of data, an average value and a variance value (variation) of the plurality of data stored in an arbitrary file format are obtained using spreadsheet application software such as MS-Excel. Had been saved as a separate file.
[0001]
FIG. 3 shows a flowchart of a conventional measurement method. In step S101 shown in FIG. 3, the operator specifies the data measurement interval (sampling time Δt) and the number of data measurements (sampling number n) to the measurement software.
[0002]
In step S102, the measurement software sends an instruction to the measurement device to capture data of the number of samplings n, which is measured for each sampling time Δt, and displays the captured data on the display.
[0003]
In step 103, the measurement software saves the acquired data together with time information in an arbitrary file format. FIG. 4 is a diagram showing a configuration of data to be stored. As shown in FIG. 4, the measured time and the measured data D (i), data E (i), data F (i),... Are set as one set (i = 1, 2,. ), N sets of data are saved in a data file.
[0004]
At step 104, the operator moves the data of the n sets of data from the data file storing the n sets of data to the spreadsheet application software using spreadsheet application software such as MS-Excel. create.
[0005]
In step S105, values such as an average value and a variance value of each data are obtained in the table of n sets of data using spreadsheet application software.
[0006]
In step S106, the average value, variance value, and the like of the obtained data are stored in a data file different from the data file created in step S103.
[0007]
In step S107, it is determined whether there is another measurement point. Here, when there is another measurement point, steps S101 to S107 are repeated, and when there is no other measurement point, the measurement ends.
[0008]
In this manner, a plurality of data can be measured at one or a plurality of measurement points, and an average value, a variance value, and the like of the plurality of data measured at each point can be obtained.
[0009]
However, when calculating an average value, a variance value, and the like of data at each of a plurality of measurement points, it is necessary to process a plurality of data files for each measurement point using spreadsheet application software or the like. Therefore, there is a problem that the load of this work cannot be ignored as the number of measurement points increases.
[Problems to be solved by the invention]
In view of the above, the present invention provides a measurement method that reduces the load on an operator by automatically calculating and processing an average value, a variance value, and the like of data measured at each measurement point. With the goal.
[Means for Solving the Problems]
In order to solve the above problems, a measurement method according to the present invention is a method of performing measurement by controlling a measurement device using at least one computer, and processing data obtained by the measurement. (A) performing a predetermined number of measurements at predetermined time intervals by controlling the measuring device using the computer, and loading a plurality of data obtained by the measurement into the first computer; A step (b) of obtaining statistical data by performing statistical processing based on the plurality of fetched data; and a step (c) of writing the statistical data obtained in step (b) to a clipboard of a second computer. Have.
[0010]
According to the measurement method according to the present invention configured as described above, the average value, the variance value, and the like of the data measured at each measurement point are automatically calculated and written to the clipboard. Necessary data can be easily pasted simply by making a copy on application software such as, so that the load on the operator can be reduced and the work efficiency can be improved.
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 shows a flowchart of a measurement method according to an embodiment of the present invention. In step S1 shown in FIG. 1, the operator specifies to the measurement software the data measurement interval (sampling time Δt) and the number of data measurements (sampling number n).
[0011]
In step S2, the measurement software fetches data of the number of samplings n measured at every sampling time Δt by sending a command to the measurement device, and displays the fetched data on a display.
[0012]
In step S3, the measurement software obtains an average value, a variance value, and the like of each data acquired by the n measurements after the n measurements are completed.
[0013]
In step S4, in order to handle the data on different software, an average value, a variance value, and the like of the obtained data are written to a clipboard of a computer that controls the measuring device or another computer. FIG. 2 shows the format of the data written on the clipboard. FIG. 2 is an example showing the X average value, X variance value, Y average value, Y variance value, Z average value, and Z variance value of the three-axis sensor. As shown in FIG. 2, the average value and the variance value of each data are delimited by TAB and written on the clipboard.
[0014]
In step S5, the operator copies the average value, variance value, and the like of the data written on the clipboard to application software such as MS-Excel, and saves the data file in step S6.
[0015]
In step S7, it is determined whether there is another measurement point. Here, when there is another measurement point, steps S1 to S6 are repeated, and when there is no other measurement point, the measurement ends.
