DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a device for collecting a large amount of experimental data at regular time intervals, such as a nuclear fusion experimental device.

[Technical background of the invention and its problems]

FIG. 6 shows the general configuration of this type of data collection device.

In the figure, 1 is a housing called a crate, 2
is a transient recorder (TR) that performs AD conversion, 3 is a memory (MEM) that stores AD-converted data, and 4 is a transient recorder 2
is a clock pulse generator (CPG) that supplies a clock for sampling; 5 is a data transmission path called a highway for exchanging data; 6 is a computer that performs data collection processing; and 7 is a display of the processing results of computer 6. This is a display device such as a CRT.

As illustrated, the crate 1 is equipped with modules such as the above-mentioned transient recorder 2, memory 3, and generator 4.

As described above, in nuclear fusion experimental equipment and the like, a data collection device such as a transient recorder is used to sample a large amount of data generated in a short period of time at high speed. In particular, in nuclear fusion experimental equipment, it is necessary to flexibly adapt the measurement system to various experimental conditions, and the generated data is immediately collected and processed by a computer, so CAMAC
(Computer Automated Measurement and
A data collection device with a general-purpose interface standard, such as ``Control'', is used.

FIG. 7 shows a conventional configuration of such a data collection device. FIG. 8 is a timing chart for explaining the operation.

In FIG. 7, 3 and 7 are the memory and display device respectively explained in FIG. 5, 8 is a data collection means, 9 is a data collection information file, 10 is a collection data file, 11 is a data display means, and 12 is a data display It is an information file.

Here, the memory 3 has l pieces MEM1 to MEMl, and the data names DATA1 to DATAm are used to distinguish the data sampled for each channel of the transient recorder 2 (Fig. 6). It stores the physical address of the memory, memory capacity (number of words), etc.

The data collection information file 9 is one for each memory.
It consists of data files, and there are l data files corresponding to the number of memory modules. The contents are set in Man-Machine language.

The data collection means 8 transfers data from the corresponding module of the memory 3 based on the information in the data collection information file 9. This transferred data is stored in the collected data file 10 together with the collected information.

The data display information file 12 consists of data files corresponding to the number of pages on the display screen, and one data file stores the data names DATAi1 to DATAin of the data to be displayed on the page of the screen, the data display format, etc. . Its contents are set in man-machine language like file 9, but it is independent from file 9.

Next, the operation of this conventional device will be explained.

Data accumulated in the memory 3 from an external device (not shown) is first collected from the memory 3 via the data collection means 8 according to the contents of the data collection information file 9. Among the collected data, necessary data is displayed on the display device 7 by the data display means 11 according to the contents of the data display information file 12.

The above operation is shown in FIG. 8 as a time chart.
Figure a shows time 70 when one plasma experiment was conducted.
, b indicates a storage transfer operation of the memory 3, c indicates a processing operation of the computer 6, and d indicates a display operation of the display device 7.

Here, as mentioned above, the contents of the data collection information file 9 and the data display information file 12 are set independently, so the data collection information file 9 in which the data name collected by the data collection means 8 is registered is Data order DATA1~
DATAm and the data order DATAi1~ of the data display information file 12 in which the data name to be displayed on the display device 7 by the data display means 11 is registered.
Generally does not match with DATAin.

Therefore, for example, the data names on the first page of the data display information file 12 in FIG. 8, that is, the experimental data DATAi1 and DATAi2 displayed first on the display device after the end of the experiment 70, are the data names of the data displayed on the first page of the data display information file 12 in FIG. It is output from the computer 6 and displayed on the display device 7 at times t1 and t2 during the period 71.

By the way, in nuclear fusion experimental equipment, discharge experiments are carried out at fixed time intervals such as 3 or 5 minutes, but in order to increase the efficiency of the experiment, the results of the previous experiment (usually displayed in graphs, etc.) are It is preferable for the operator to check and study the results on the display device, and then carry out the next experiment while reflecting the results of the study.

To do this, use Transient Recorder 2.
It is required that the AD-converted experimental data stored in the memory 3 be transferred to the computer 6 immediately upon completion of data sampling, and displayed on the screen of the display device 7 as soon as possible after necessary processing.

However, the amount of experimental data collected from the fusion experimental device is enormous, and the time required to transfer it is also large, so the next experiment will start before all experimental data has been displayed. . In this case, if the experimental data that is not displayed is not very important, there is no problem because it can be displayed slowly over time after the experiment is completed.

However, in the conventional device described above, there is no relationship between the data transfer order and the display order, so data that is later in the display order is often transferred first, and the display time increases. It was unnecessarily long. As a result, the next experiment ends up starting before important experimental data is displayed, and the operator is often unable to conduct the next experiment after considering the previous experiment results.

[Purpose of the invention]

This invention was made in order to eliminate the drawbacks of the above-mentioned prior art, and in order to efficiently conduct the next experiment based on the results of the previous experiment, necessary The purpose of the present invention is to provide an actual data collection device that can quickly display accurate data.

[Structure of the invention]

In order to achieve the above object, the present invention provides a data collection means for extracting experimental data from a memory storing experimental data from an experimental device, based on management information of the data collection information file, and creating a collected data file. , a data display means for displaying the data collected in the collected data file on a screen of a display device in a predetermined order based on display order information from a data display information file; data display priority determining means for creating a prioritized data collection information file by adding priority information regarding display order to management information of the data collection information file based on display information from the data display information file; The data collecting means creates the collected data file based on the prioritized management information from the prioritized data collection information file.

[Embodiments of the invention]

Embodiments of the present invention will be described below with reference to the accompanying drawings. The same reference numerals in each figure indicate similar objects.

FIG. 1 is a system diagram showing a data collection device according to an embodiment of the present invention.

In the figure, 3 and 7 are the memory and display device respectively explained in FIG.
and a data display information file; 13 is a data display priority determining means; and 14 is a data collection information file with priority.

Here, memory 3 is MEM1 to MEM1 as described above.
There are 1 MEMl, transient recorder 2
Data names DATA1 to DATAm to distinguish the data sampled for each channel in (Figure 5),
It stores the physical address of the memory on the highway 5, the memory capacity (number of words), etc.

The data collection information file 9 is also the same as described above, and consists of one data file for each memory, and there are l pieces corresponding to the number of memory modules. The contents are set in Man-Machine language.

The data collection means 8 is also the same as described above, and based on the information in the data collection information file 9, data is transferred from the corresponding module in the memory 3. This transferred data is stored in the collected data file 10 together with the collected information.

The data display information file 12 is also the same as described above.
It consists of data files corresponding to the number of pages on the display screen, and one data file contains the data name DATAi1~ of the data to be displayed on the page on the screen.
DATAin, data display format, etc. are memorized. Its contents are set in man-machine language like file 9, but it is independent from file 9.

The data display priority determination means 13 sets priorities in the display order of information determined by the data display information file 12 based on the contents of the data collection information file 9. That is, the data numbers DATAi1 to DATAin of the data display information file 12 are added to the contents of the data collection information file 9.

The prioritized data collection information file 14 is a data collection information file prioritized by the data display priority determining means 13 in this way.

The configuration of the data display priority determination means 13 is as shown in FIG.

According to the figure, data display priority determining means 13
is a main control unit (CPU) 20, two memories (ROM, RAM) 21, 22, a data bus 23,
and an interface 24.

The CPU 20 includes a counter 20A that specifies the order of the prioritized data collection information file 14. The ROM 21 stores programs to be executed by the CPU 20, and ultimately stores the data display information file 12 as described above.
Priorities are set in the order of information collection determined by the contents of the data collection information file 9, and a prioritized data collection information file 14 is formed. The explanation of other constituent elements is omitted because it seems unnecessary.

The operation of this data display priority determining means 13 is as follows:
This will be explained below with reference to the flowchart shown in FIG. In the following description, the numbers in parentheses correspond to the number of each block in the flowchart of FIG.

First of all, when the device starts up, the CPU 20
The content J of the own counter 20A, which specifies the order of the prioritized data collection information file 14, is set to "0" and initialized (301).

Next, in order to prevent multiple priority data collection information files 14 having the same data name from occurring, the data names DATAi ₁ to DATAin stored in the data display information file 12 are assigned to the priority data collection information file 14. The process begins to check whether the file is unregistered (302). If the result of this check (303) is that it has not been registered, the counter 20A is counted up and J=J+1 is set (304).

After this, the data in data collection information file 9
Search for the memory MEMji where DATAii is registered,
Information necessary to collect the data DATAii, such as the name of the memory MEMji, the channel number in that memory, and the number of transferred words, is registered in the Jth priority data collection information file 14 (305).

By the processing up to this point, the registered data names DATAi1~ of the data display information file 12 are
Data names are registered in the prioritized data collection information file 14 in the order of DATAin, excluding duplicate data names.

Next, the process of registering collection information necessary for collecting data that is registered in the data collection information file 9 but not registered in the data display information file 12 in the prioritized data collection information file 14. explain.

First, a step begins in which it is checked whether the collection information with the data name DATAI registered in the data collection information file 9 has already been registered in the prioritized data collection information file 14 (306). If the result of this check (307) is not registered, the counter 20
The contents of A are counted up as J=J+1 (308).

After this, the information necessary to collect the data DATAI, such as the name of the memory MEMji, the channel number in that memory, the number of transferred words, etc., is registered in the Jth priority data collection information file 14 (309) and processed. end.

As described above, through the process shown in FIG. Data information is registered. In actual data collection, for example in a nuclear fusion experimental device, the prioritized data collection information file 14 is created at the time when discharge preparation is completed. When the experiment is completed, the data collection means 8 follows the order of the prioritized data collection information file 14 and collects the data DATAi1.
Start collecting data. Therefore, as shown in FIG. 4, data can be displayed in the shortest possible time after the experiment is completed.

In Fig. 3, 301 to 305 are steps for efficient data transfer, and 306 to 309 are steps for efficient data transfer.
is a step for efficient data collection. As is clear from FIGS. 4 and 8, the time required for data transfer is much longer than the time required for data collection, so steps 301 to 305 alone are sufficient to achieve the purpose of the present invention. It is. However, in this embodiment, in order to further improve efficiency, priority is given to the order of data collection as in steps 306 to 309.

As explained above, according to this embodiment, even if data collection information and data display information are set independently, prior to data collection, the data is first sorted in the order in which it is registered in the data display information file 12. Register the data collection information of names DATAi1 to DATAin in the priority data collection information file 14, then register the data collection information of the data name registered only in the data collection information file 9, and then Since the means 8 collects data in accordance with the prioritized data collection information file 14, data processing and display can be executed at high speed.

FIG. 5 is a system diagram of an apparatus according to a second embodiment of the invention.

In the embodiment shown in FIG. 1, one piece of prioritized data collection information is created for one data name, and a collection data file is created for each data name. When storing and recalling data (once stored on a magnetic tape, etc., and then loading and processing this data again as needed), the collected data is stored in memory units as shown in the collected data file 10 in Figure 7. In some cases, it may be more convenient to manage files. This second embodiment meets this need.

In this embodiment, a collection data file creation means 15 is added to the configuration shown in FIG. The other components are the same as those in FIG. 1 or 6, and their explanation will be omitted.

The collection data file creation means 15 secures an area necessary for transferring data in each memory MEM1 to MEMl of the collection data file 10, and also stores memory name MEMi and channel information (data name
DATA1 to DATAm, number of words of each data, etc.)
In addition to writing collected information such as
DATA1~DATAm is already memory MEM1~
Clear the flag indicating that the data has been transferred from MEMl to the data collection information file 14. Here, this flag is assumed to be in the collected data file 10, but it may be provided separately.

Next, the operation of this embodiment will be explained.

Similar to the embodiment shown in FIG. 1, the prioritized data collection information file 14 is created, for example, at the time when preparation for electric discharge is completed in a nuclear fusion device. At the same time, each memory MEM1 to
The collection data file 10 necessary to transfer the data of MEMI is secured, and the collection information of each memory is written to it from the data collection information 9, and the transferred flags of data names DATA1 to DATAm are cleared.

When the experiment is completed, the data collection means 8 transfers the data from the memory MEMi to a predetermined channel area of the collection data file in the memory based on the information in the prioritized data collection information file 14, and then transfers the data with this data name. Set the transferred flag.

The data display means 11 displays data names DATAi1 to 1 from the prioritized data collection information file 14.
The data transfer completion flag corresponding to the memory names MEMj1 to MEMjm of the collected data file 10 in which the data of DATAim is stored is checked, and if this flag is set, it is displayed on the display device 7.

As described above, according to this embodiment, it is possible to display data in the shortest possible time from the end of an experiment while managing the collected data file 10 in units of memories MEM1 to MEM1.

Generally, an auxiliary disk device such as a magnetic disk device is used as the collected data file 10, but the main memory of the computer is used instead of this file, and the data collected from the memory 3 is temporarily stored in the main memory of the computer. Another possible method is to transfer the data to the auxiliary disk device using free time until the next experiment. According to this method, data can be displayed without exchanging data with the magnetic disk device, so the time from the end of the experiment to the data display can be further shortened.

〔Effect of the invention〕

As described above, according to the present invention, when experimental data is retrieved from the memory and transferred to the display means, the transfer order is made to correspond to the display order, so that the necessary data from the previous experiment is transferred to the next experiment. It can be displayed immediately before the experiment starts.

Therefore, it is possible to adjust the conditions for the next experiment based on the results of the previous experiment, and it becomes possible to conduct the experiment with high efficiency.
