DETAILED DESCRIPTION OF THE INVENTION

[0001]

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

[0002]

2. Description of the Related Art In recent analysis apparatuses, for example, a particle size distribution measurement apparatus, a computer is used to perform pre-processing and measurement in accordance with a program, and to process data obtained by the measurement.

[0003]

By the way, in the particle size distribution measuring apparatus, regardless of the automatic wet method or the dry method, the sample preparation method causes segregation of particles, etc.
The measurement result is affected. Therefore, a predetermined procedure must be performed for each sample as a pretreatment for measurement.
This was extremely inconvenient for the operator. Regarding data processing after measurement, these processings are often different for each sample. If these procedures are to be realized in advance by the main unit software, software that describes these procedures for each sample is required, and it is necessary to use sequential conversion software such as setting parameters for measurement and data processing. However, there is a drawback in that even if the analyzer is mounted on such an analyzer, it is difficult for an on-site operator to understand.

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

In this drawing, 1 is a measuring device main body, and 2 is an automatic dilution unit. Reference numeral 3 denotes an autosampler, which constitutes a particle size distribution measuring device. Reference numeral 4 denotes a computer which controls the measuring apparatus main body 1, the dilution unit 2, and the autosampler 3 in accordance with a processing sequence described later, and appropriately processes data transmitted from the measuring apparatus main body 1 side. The computer 4 is configured to operate by a program for conversion and translation, and is connected to a keyboard 5A and a mouse 5B as input devices and a graphic display 6 as a display device.

FIG. 2 schematically shows the internal configuration of the computer 4.
PU, 42 is a disk unit, 43 is a memory unit, 44 is a graphic I / F, 45 is a serial I / F
The CPU 41 and each of the units 42 to 45 are connected by a CPU bus line.

FIG. 3 shows the graphic display 6.
In this figure, reference numeral 60 denotes a screen, on which scroll bars 61 are provided on both sides and at the bottom. Reference numeral 62 denotes an instruction block a in which an operation (function) to be performed by the analyzer is expressed in a simple language.
Are collectively displayed, 63 are INS (insertion), DEL (deletion), PASTE (deletion return), NE
Keys representing various functions such as XT (next page) and BACK ( previous page), and 64 is 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. When performing a particle size distribution measurement, functions to be performed by the measuring device, for example, CIRCULATION (sample circulation), AGITATION (sample stirring), Wa
it (standby), AUTOSMP (autosampler drive), RINSE (wash), Blank (blank measurement), File SAVE (file storage), Feed
Instruction block a written in a simple language (such as a simple character or symbol picture) such as (dispersion medium supply)
And displays it on the screen 60. These instruction blocks a are the same as the operation of a normal software program, and can be “sequentially”, “determined”, and “repeated”.

In addition to the above-mentioned simple language, PRE1 (in which a specified amount is injected under the current measurement conditions, then stirring, circulation, ultrasonic dispersion are performed, and ultrasonic time-up is waited), P1
RE2 (automatic dilution under current measurement conditions), USON
(Sets ultrasonic ON / OFF and ultrasonic operation time), ACTRUN (measurement conditions, stirring motor,
Circulating motor, operating ultrasonic wave), USWAIT (wait until the currently operating ultrasonic wave times out), SE
TCONC (determines the threshold level of the appropriate concentration range of the dispersion medium. The set value checks that the relationship of LOW <HIGH is set at the time of editing), CHKCONC (takes in the scattering patterns for the number of data acquisition times of the measurement conditions,
Perform a density check. When the density exceeds the density range set by SETCONC, the language jumps to a JMP label set by a value.

In the particle size distribution measuring device, various conditions need to be set, and these conditions are different for each sample. Therefore, a simple language is set for each operation, and these are combined on a screen. By simply editing, complicated condition settings can be easily and visually performed. As described above, the present invention has a special effect in the particle size distribution measuring device.

For editing the processing sequence, a desired processing sequence is created by arranging, linking, or deleting the instruction blocks a. The processing sequence created in this way can be executed by being developed in the disk unit 42 and the memory unit 43 in the computer 4 and stored in the disk unit 42 as sequence data. The disk unit 42 can save and store all the processing sequences.

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

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

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

As described above, according to the present invention, the instruction blocks written in a simple language on the screen are simply edited by appropriately combining or inserting the instruction blocks. No need to change. In addition, since this editing operation can be performed without knowledge of software, a programming language, and the like, a desired processing sequence can be easily created.
