Abstract

PROBLEM TO BE SOLVED: To obtain a data processor which shortens the waiting time until a computed result is displayed after an operator has performed an input operation. SOLUTION: When a computing quantity is large, a proper thinning-out processing operation is performed from many pieces of data (S4), a prescribed computing operation is executed to data in a quantity which is small as compared with the total quantity of data, and a computed result is obtained (S5). Then, while an approximate result is displayed on a display (S6), a prescribed computing operation is executed to all pieces of data including the many pieces of data other than extracted data (S7). At a point of time when the computing operation of all the pieces of data is finished, a final computed result is displayed instead of a screen which is displayed before (S8). As a result, the waiting time until a display is shortened sharply.

2. Description of the Related Art FIG. 5 is a schematic configuration diagram of a general Fourier transform infrared spectroscopic measuring apparatus. The interferometer 10 includes the light source unit 1
1, parabolic mirror 12, beam splitter 13, fixed mirror 1
4, a moving mirror 15, an ellipsoidal mirror 16 and the like, which generate interference infrared light for performing spectrum measurement. That is, the infrared light emitted from the light source unit 11 is emitted from the parabolic mirror 1.
The light is reflected at 2, and is split into both the fixed mirror 14 and the moving mirror 15 by the beam splitter 13. The light reflected by each of the fixed mirror 14 and the movable mirror 15 is sent to the optical path toward the ellipsoidal mirror 16 by the beam splitter 13. At this time, since the movable mirror 15 is moving back and forth,
The light traveling from the beam splitter 13 to the ellipsoidal mirror 16 becomes interference infrared light whose amplitude fluctuates with time.

The light condensed by the ellipsoidal mirror 16 is reflected by the window plate 1
After being sent to the sample chamber 20 through the sample 7 and passing through the sample 21 such as the solution placed in the sample chamber 20, the ellipsoidal mirror 22
It is reflected by and is condensed on the photodetector 23. Photodetector 23
The detection signal of 1 is amplified by the amplifier 24 and then converted into a digital signal by the A / D converter 25. The converted data is sent to a personal computer (hereinafter referred to as “personal computer”) 30, and is stored in an external memory 32 such as a hard disk connected thereto or a random access memory (RAM). In addition to the external memory 32, a keyboard 31, a display 33, and a printer 34 are connected to the personal computer 30. The operator operates the keyboard 31
By inputting an analysis instruction or the like by operating, the personal computer 30 executes a data processing operation such as a Fourier calculation on the data stored in the external memory 32 in response to the instruction, and transmits the transmittance or the reflectance. A spectrum or the like is created and output to the display 33 or the printer 34.

[0004]

In the conventional data processing apparatus mainly composed of the personal computer 30 as described above, when a command to start the calculation is received from the keyboard 31, the data is stored in the external memory 32 or the RAM. The data is read out, a predetermined calculation is executed, and when all necessary calculations are completed, the calculation result is displayed on the display 33. However, since it is usually necessary to perform a complicated calculation on an extremely large amount of data, the calculation process takes time. Therefore, after the operator gives an instruction to start the calculation by a predetermined operation from the keyboard 31,
It may take several seconds to ten seconds or more until the resulting graph or the like is displayed on the display 33, and in some cases, several tens of seconds. The operator must wait for the results to be displayed during this time. This is not only inferior to the operator in terms of comfort during use, but also a problem that appropriate information cannot be given even when the operator wants to know the outline of the result.

The present invention has been made to solve the above problems, and an object of the present invention is to provide an operator with a comfortable working environment and to perform efficient measurement work. To provide a data processing device.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In the data processing apparatus according to the present invention, when the input means is instructed to start the calculation, first, the judging means calculates the outline of the total calculation amount and compares it with a predetermined reference. to decide. When it is determined that the total amount of calculation is equal to or larger than the predetermined amount, the extracting unit appropriately performs thinning processing from a large number of numerical data, and extracts a data amount smaller than the total data amount. Then, the calculation means performs a predetermined calculation on the extracted data to obtain a calculation result. The calculation result is sent to the display control means and displayed on the display means. When the previous operation is completed and the next operation is ready to be executed, the operation means executes a predetermined operation on the entire data including a large number of data not extracted by the extraction means. That is, while the result of the previous calculation is displayed on the display unit, the calculation unit executes the calculation on the entire data. Then, when the calculation of all data is completed, the display control means displays the final calculation result instead of the screen previously displayed on the display means. When performing the calculation on the entire data, the calculation on the extracted data, which has already been calculated, may be excluded.

As the thinning-out processing in the extracting means, an appropriate method can be adopted depending on the type of numerical data and the contents of calculation. For example, in the simplest case, a predetermined interval (temporal interval, spatial interval, etc.) can be used. ), The data may be selected for each. If the screen of the display means has a low resolution (coarse), data may be extracted according to this resolution.

[0009]

According to the data processing device of the present invention,
After the instruction of the arithmetic processing, first, a rough arithmetic result based on a relatively small number of data is displayed, and after a lapse of time, the display content is updated to a detailed arithmetic result based on all the data.
For this reason, after the operator performs the input operation, the result is displayed promptly, and the operator is relieved from feeling a long waiting time. Further, since the operator can quickly know the outline of the result, it is possible to judge and execute the next necessary work depending on the contents, and the work efficiency is improved.

Further, especially when it takes a long time to obtain the final calculation result, it is possible to determine whether or not the operator is worth continuing the calculation by the outline of the result displayed first. It is also possible to make a judgment and perform an operation for interrupting the calculation if it is unnecessary. This saves time by not wasting your computer for unnecessary calculations, and improves your computer's efficiency when you're using it by connecting it to multiple terminals. You can

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a data processing device according to the present invention will be described with reference to FIGS. FIG. 1 is a block diagram of a data processing device according to this embodiment, and FIG. 2 is a flowchart showing a processing procedure in this data processing device.

This data processing apparatus includes an input unit 40 such as a keyboard, an arithmetic control unit 41 which receives an instruction from the input unit 40 and controls arithmetic processing, a storage unit 42 such as an external memory, and a data storage unit 42. It is composed of a data reading unit 43 that controls reading, a calculation unit 44 that executes a predetermined calculation, and a display control unit 45 that controls display on the display 33.

First, when an instruction to start arithmetic processing is given from the input section 40 by a predetermined operation (step S1), the arithmetic control section 41 estimates the total arithmetic amount based on the total number of data required for calculation (step S1). S2), and compares this with a predetermined reference (step S3). As a method of estimating the calculation amount, various methods can be used, for example, the header part of the data file is read and the calculation amount is estimated from the file size stored therein.

If the calculation amount is below the predetermined reference in step S3, the process proceeds to step S9, the data is sequentially read from the storage unit 42 and sent to the calculation unit 44, and the calculation unit 4
4 executes arithmetic processing on the data. When the arithmetic processing on all data is completed, the arithmetic processing result is sent to the display control unit 45 and accumulated in the internal frame memory. Further, it is sent from the display control unit 45 to the display 33 and displayed as a graph or the like on the screen (step S10).

On the other hand, if the amount of calculation is equal to or greater than the predetermined reference in step S3, the process proceeds to step S4, and the data reading section 43 first causes the storage section 42 to extract and read the data according to a predetermined rule. Control. Then, the calculation unit 44 executes a predetermined calculation process on the extracted data (step S5). Here, the total number of extracted data is set to be far smaller than the original total number of data. Therefore, the time required to complete the arithmetic processing on the extracted data can be considerably shorter than the time required for the arithmetic processing on all the data. When this arithmetic processing is completed, the result is sent to the display 33 via the display control unit 45 and displayed as a graph or the like on the screen (step S6).

Next, the data reading section 43 sequentially reads the remaining data other than the previously extracted data, and the storage section 42.
Control. The calculation unit 44 executes a predetermined calculation process on this data (step S7). When the calculation processing of all the remaining data is completed, the result is displayed by the display control unit 45.
Is sent to the display 33 via. As a result, the display 33 displays a graph or the like of the calculation result based on all the data, instead of the calculation result already displayed (step S8).

Although the series of processes described above is actually performed in the personal computer 30 centered on the CPU, for example,
It is also possible to use a dedicated digital signal processor (DSP) or the like in order to perform a predetermined calculation at high speed.

Next, the arithmetic processing when the data processing apparatus as described above is applied to the Fourier transform infrared spectroscopic measuring apparatus will be concretely described with reference to FIGS. 3 and 4. In the Fourier transform infrared spectroscopic measurement device as shown in FIG.
It is often practiced to calculate the difference between spectra of the target sample to be measured and the reference sample, and display the difference on the display 33 as a difference spectrum. In this case, the spectrum of the sample to be measured (hereinafter "sample spectrum"
Data) and the reference sample spectrum (hereinafter referred to as the “reference spectrum”) are obtained discretely, so depending on the measurement conditions, the wave number position of the data in the sample spectrum and the wave number of the data in the reference spectrum The position does not always match.

That is, as shown in FIG. 3, the sample spectrum (see FIG. 3A) and the reference spectrum (see FIG. 3).
If the wave number positions of the data in (b) do not match, the relative processing corresponding to the wave number position of the data in the reference spectrum is performed by performing arithmetic processing on each data of the sample spectrum before obtaining the difference in relative intensity. Strength (Fig. 3 (c)
Need to be calculated). Such an arithmetic process is quite complicated, and moreover, since it has to be performed on all the data constituting the spectrum, the amount of arithmetic operation becomes enormous.

It is assumed that the sample spectrum and the reference spectrum each consist of 5000 pieces of data, and each data is represented by the coordinate value of (x, y). That is, x is a value on the wave number axis and y is a value on the relative intensity axis.
Data processing from the calculation of the difference spectrum from the large number of data to the display thereof is executed according to the flowchart of FIG. 4, which embodies the flowchart of FIG.

First, when the input section 40 is instructed to start the calculation process (step S11), the calculation control section 41 sets the data of the sample spectrum in order to make the standard of the relative intensity of the sample spectrum and the reference spectrum uniform. The coefficient α for multiplying the y value of is determined (step S12). That is, when the measurement conditions of the sample to be measured and the reference sample, for example, the concentration of the sample solution and the like are different, a more accurate difference spectrum can be calculated by setting a coefficient according to the concentration difference. . Such a coefficient may be configured such that the operator can input the coefficient by himself / herself, or when the operator inputs a condition such as density, a coefficient corresponding to the condition may be calculated. good.

Next, the arithmetic control unit 41 roughly estimates the arithmetic time when the later-described arithmetic operation is performed on all the data from the total data amount (step S13). Now, assuming that, for example, the arithmetic processing of about 1000 data can be executed in one second, the total arithmetic time is about 5 seconds. Therefore, for example, when the determination criterion in step S3 of FIG. 2 is 2 seconds, the process proceeds to step S14 and thereafter.

The y value of the sample spectrum corresponding to the wave number position (x value) of every 50 data in the wave number direction on the reference spectrum as shown in FIG. 3A is calculated. Since the calculation of this value is performed using two or more pieces of data continuous in the wave number axis direction of the sample spectrum, the data reading unit 43 controls the storage unit 42 so as to read the data necessary for the calculation, and performs the calculation. The unit 44 obtains the y value on the sample spectrum so as to calculate the data shown in FIG. 3C from the data shown in FIG. 3B (step S14). The number of data obtained by this calculation is 1/50 of 10
It becomes zero.

By the above calculation, 50 on the reference spectrum is obtained.
Since the relative intensity (y value) of the sample spectrum corresponding to the wave number position of each piece of data is obtained, this relative intensity is multiplied by the previously determined coefficient α, and then the difference between the relative intensities of the two is calculated for each wave number position. Calculate (step S15). And 50
When the calculation processing of the data for each piece is completed, the calculation result for one frame is sent to the display 33 via the display control unit 45. As a result, the display 33 displays the difference spectrum in which the horizontal axis and the vertical axis represent the wave number and the difference data, respectively (step S16).

When the previous calculation in the calculation unit 44 is completed, the data reading unit 43 then reads the data of a predetermined sample spectrum for calculating the data other than the data of every 50 pieces extracted previously, and the calculation unit 44 executes the same arithmetic processing as this in steps S14 and S15 for this data (steps S17 and S18). Then, when the calculation of all the remaining data is completed, one frame of data is sent to the display 33 via the display control unit 45, and the spectrum display on the screen previously displayed is updated (step S19). ).

By performing the data processing as in the present invention, the waiting time of the operator is shortened as follows. For example, in the conventional data processing method, a waiting time of about 5 seconds is required to process 5000 pieces of data, and about 1 second is required to display the result on the display 33, that is, a total waiting time of about 6 seconds. I shall. On the other hand, in the data processing device of the present invention, a waiting time of about 1.1 seconds is required before the outline of the difference spectrum is first displayed. Therefore, the operator can quickly confirm the result after the input operation.

It should be noted that the embodiment described above is merely an example, and it is apparent that appropriate changes and modifications can be made in accordance with the spirit of the present invention.
