BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an analytical device such as a particle size distribution measuring device.

[0002]

2. Description of the Related Art In recent analyzers, such as particle size distribution measuring devices, a computer is used to perform preprocessing and measurement according to the program, and data obtained by the measurement is processed.

[0003]

By the way, in the particle size distribution measuring apparatus, regardless of whether it is an automatic wet method or a dry method, the sample preparation method causes segregation of particles, etc.
The measurement result is affected. Therefore, it is necessary to perform a fixed procedure as a pretreatment of measurement for each sample,
It was very inconvenient for the operator. Also, with respect to data processing after measurement, generally, these processing often differ for each sample. If these procedures are to be realized by the main body software in advance, software that describes these procedures for each sample is required, and even if it is a sequential conversion type software that sets parameters for measurement and data processing. However, there is a drawback in that it is difficult for an operator in the field to understand even if is installed in such an analyzer.

The present invention has been made in consideration of the above matters, and a series of processing sequences such as measurement and data processing in an analyzer such as a particle size distribution measuring device can be easily performed without changing software in a computer. It is an object of the present invention to provide an analysis device that can be prepared in the above.

[0005]

In order to achieve the above-mentioned object, the present invention relates to an analyzer configured to perform an analysis based on a command from a computer, wherein each operation performed by the analyzer is By graphically displaying as a command block on the screen of the graphic display connected to the computer, and editing the command block graphically displayed on the screen of the graphic display by using the input device connected to the computer. A desired processing sequence is created.

[0006]

In the above analyzer, the operation desired to be performed by the analyzer is graphically displayed as a command block on the screen of the graphic display. Then, a desired processing sequence can be easily created without changing the software in the computer simply by editing by appropriately combining or inserting the instruction blocks on the screen. According to this method, a desired processing sequence can be easily created without knowledge of software or programming language.

The CPU 41 and the respective units 42 to 45 are connected by the CPU bus line.

FIG. 3 shows the graphic display 6
An example of the edit screen displayed on the screen is shown. In this figure, 60 is a screen, and scroll bars 61 are provided on both sides and the lower part thereof. Reference numeral 62 is an instruction block a that represents the operation (function) to be performed by the analyzer in a simple language.
63 is a display area for collectively displaying, INS (insert), DEL (delete), Paste (delete return), NE
Keys representing various functions such as XT (next page) and BACK (all pages), and 64 are an example of a dialog box showing editing contents.

Next, the operation of the particle size distribution measuring device having the above configuration will be described. Functions to be performed by the measuring device when measuring the particle size distribution, for example, CIRCURATION (sample circulation), AGITATION (sample agitation), Wa
it (standby), AUTOSMP (auto sampler drive), RINSE (cleaning), Blank (blank measurement), File SAVE (file storage), Feed
The instruction block a written in a simple language (such as simple characters or symbol pictures) such as (supply of dispersion medium) is used by the mouse 5A.
To be displayed on the screen 60. These instruction blocks a are the same as the operations of a normal software program, and can be “sequential”, “judgment”, and “repeat”.

In addition to the simple language, PRE1 (after injecting a specified amount under the current measurement conditions, stirring, circulating, and ultrasonic dispersion are performed, and waiting for ultrasonic time-up), P
RE2 (automatic dilution under current measurement conditions), USON
(Set the ultrasonic ON / OFF and ultrasonic operation time), ACTRUN (agitating motor depending on the content of the measurement conditions,
Circulation motor, ultrasonic wave is operated), Uswait (wait until the ultrasonic wave currently in operation is up), SE
TCONC (determines the threshold level in the proper concentration range of the dispersion medium. Checks that the setting value is LOW <HIGH at the time of editing), CHKCONC (takes in the scattering pattern for the number of times of data acquisition of measurement conditions,
Check the concentration. There is a simple language such as (jump to the JMP label set by the value when the concentration range set by SETCONC is exceeded).

Further, in the particle size distribution measuring apparatus, various conditions must be set, and since these conditions are different for each sample, a simple language is set for each operation and these are combined on the screen. , It is possible to easily and visually set complicated condition settings just by editing. As described above, the present invention exerts a particular effect in the particle size distribution measuring device.

Then, in editing the processing sequence, a desired processing sequence is created by arranging, linking or deleting the instruction blocks a. The processing sequence thus created becomes executable by being expanded in the disk unit 42 and the memory unit 43 in the computer 4, and is stored in the disk unit 42 as sequence data. The disk unit 42 can save and store all processing sequences.

The sequence data stored in the disk unit 42 as described above is expanded in the memory unit 43 and interpreted by a sequence driving interpreter (sequential translation type language processing system). Then, each instruction block a which is started and interpreted by using the input device of the keyboard 5A or the mouse 5B or a preset system clock as a trigger is read by the serial interface 4
It is sent to the apparatus main body 1 side via 5. As a result, the apparatus body 1 side executes the operation according to the instruction block a.
At this time, the command block a is displayed on the graphic display 6 via the graphic interface 44.
Is sent and the contents of the operation being executed on the device body 1 side are displayed, whereby the operator can grasp what kind of operation is being performed on the device body 1 side.

In the above-described analyzer, each operation performed by the analyzer such as measurement and data processing is graphically displayed as a simple instruction block a, and the graphically displayed instruction block a is displayed on the keyboard 5A and the mouse 5B. By using and dragging, the operation flow can be easily assembled and grasped. Then, by graphically displaying the operation content such as measurement, the operation of the created sequence can be easily confirmed, the variation of the measurement data and the erroneous operation can be minimized, and the labor saving can be promoted.

The present invention is not limited to the above-mentioned embodiments, but can be widely applied to an analyzer configured to perform an analysis based on a command from a computer.
