Reference numeral 62 denotes digital data obtained by A / D-converting the time-series data measured by the analog-type measuring device, and data for temporarily storing digital data directly output from the digital-type measuring device. It is a collection device. Reference numeral 64 denotes a large-capacity storage device for storing data stored in the data collection device 62 transferred via the data collection control calculator 63. 65 is the type of measuring instrument used, sampling time,

4 is a display terminal for retrieving and displaying the data stored in No. 4.

[0003] The operation of the data processing apparatus having the above-described configuration will be described.
An example in which the present invention is applied to a nuclear fusion experiment device will be described. First, the operator of the data processing apparatus inputs data collection conditions from the data collection control terminal 65 to prepare for the experiment. Date
After the completion of the preparation of the data processing apparatus, an experiment is started under a control device (not shown) on the side of the nuclear fusion experiment apparatus in response to a preparation completion command. The data collection device 62 stores time-series data output from the measurement device 61 during a period from when the experiment start command 67 is received from the control device to when the experiment end command 67 is received. The measurement device group for measuring the plasma electron density includes, for example, the center of the plasma, a position 10 cm away from the center,
The change of each plasma electron density at a position distant from a centimeter is measured every 10 ms, and a group of measuring devices for measuring the plasma current also measures the plasma current at various places. The time series data output from each of these measuring devices is data
After being stored in the temporary storage area of the data collection device 62, the data collection control calculator 63 receiving the experiment end command 67 transfers the data to the large-capacity storage device 64. A researcher, technician, or operator who wants to view the measurement data of the nuclear fusion experiment device has a display terminal 6.
6, the data stored in the mass storage device 64 is retrieved and displayed in a graph. The data collected in one experiment is examined after the experiment is completed, and the sequence of repeating the discussion results with a large number of people and deciding the conditions and policies for the next experiment is repeated. .

Further, for the same reason, even if a problem occurs during the experiment, there is a problem that many researchers, engineers, and drivers cannot take appropriate actions. These problems did not become apparent due to the short experimental time in the conventional experimental equipment, but need to be solved as the performance of the experimental equipment improves and the duration of one experiment increases from tens of minutes to several hours. Will occur.

When the duration of one experiment is extended, when a macro change over a long period of certain measurement data is a significant change, it becomes possible to observe the change.
