Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plurality of samples held on a sample table of a sample exchanger for carrying a sample in and out of an analyzer, and includes a type of the sample and a holding position on the sample table. The present invention relates to a sample information setting control method for setting identification data in a control device that controls the operation of an analyzer, and an analysis system.

[0002]

2. Description of the Related Art In an analysis system provided with a sample exchange for loading and unloading a sample to and from an analysis device, a specific one of a plurality of samples held vertically and horizontally on a sample table is specified. The sample of the sample exchange device is taken out by the transfer means, transferred to the input port of the analyzer, and analyzed by the analyzer. When this analysis is completed, the transport means returns the sample, transports the next sample in the same manner, and analyzes the sample with the analyzer. Such a continuous operation is
The control is performed based on the identification data relating to the sample such as the holding position of each sample on the sample table and the analysis conditions, and the analysis work data including the analysis order, which are input to the control device of the analyzer in advance by the operator.

[0003] As shown in FIG. 1B, the operator holds a plurality of samples 3 on the sample table 21 of the sample exchanger, and then, before the X-ray fluorescence analyzer starts the analysis, the analyzer. The analysis work data, which is the information necessary for the control of the work, must be entered.

The input of such analysis work data is performed on an input screen 101 on which an analysis reservation input table 150 shown in FIG. 7 is displayed.
The operator performs while watching. At the top of the analysis reservation input table 150, an item column 151 arranged in a row in the horizontal direction is displayed, and an operator who sets analysis work data can input an identification data input column for each line below the item column 151. At 156, identification data relating to the sample is input in order from the top according to the analysis order.

[0005] When inputting the holding position of the sample in the identification data, the operator enters the holding position input field 158 in FIG.
The coordinates indicating the position of the sample already held in the sample table 21 are input. For example, in the sample table 21,
The coordinate in the horizontal X direction is 2 (second from the left of the paper), and the coordinate in the vertical Y direction is 1 (1 from the top of the paper).
In the case of inputting a sample placed at the holding position, which is the third item, "2-1" is input in the holding position input field 158.

However, since the input of the data for the analysis work is performed while the operator remembers the arrangement on the sample table 21 on which all the samples are already placed or looks at the sample table 21, the operator needs to hold the sample data. When inputting the coordinates indicating the sample position on the sample table into the position input field 158, the coordinates indicating the sample position must be obtained from the image on the sample table 21 in the head. That is, the sample table 2
It is not easy to immediately recognize that the holding position is “2-1” even if the sample in which the horizontal coordinate on 1 is held at 2 and the vertical coordinate is held at 1 is held. Therefore, when inputting the sample holding position, an input error is likely to occur.

In the analysis reservation input table 150, parameters required for analysis are set in an analysis condition name input field 159, and an analysis condition name registered in advance, for example, "copper alloy" must be input. . However, it is difficult for an operator who is unfamiliar with the operation to know what to input in the analysis condition name input field 159.

Accordingly, the present invention provides a sample information setting method and an analysis system apparatus in which, when inputting identification data including a holding position on a sample table and a type of a sample, an input error hardly occurs and the input can be simplified. The purpose is to provide.

[0009]

In order to achieve the above object, a sample information setting method and an analysis system according to the present invention are provided.
For a plurality of samples held on a sample table of a sample exchange that carries samples in and out of the analyzer, identification data including the type of sample and the holding position on the sample table is used to control the operation of the analyzer. A sample information setting method to be set in the control device, on a display screen, display a plurality of sample images consisting of figures according to the type of sample and a holding position diagram showing a plurality of holding positions on the sample table, When the operator selects a specific sample image displayed on the display screen and specifies a specific holding position display in the holding position diagram, the selected sample image is superimposed on the specified holding position display. Display and reproduce the kind and arrangement of the sample actually held on the sample table, based on the sample image selected by the operator and the specified holding position display,
For the sample held on the sample table, identification data including the type of the sample and the holding position on the sample table is set in a control device that controls the operation of the analyzer.

According to this configuration, a plurality of sample images composed of figures corresponding to the types of samples and holding position diagrams indicating a plurality of holding positions on the sample table are displayed on the display screen. Can be performed while looking at the display screen, similar to the operation of actually placing the sample on the sample table, so that the operator converts the sample holding position in the head to coordinates as in the past. There is no need to do so, and input operations are simplified, and input errors are less likely to occur. Also, when the operator checks whether there is any input error, the input error can be seen at a glance simply by comparing the type and arrangement of the sample reproduced on the display screen with the actual sample table. Is easy to find.

Here, "holding position on sample table"
"Position information" is positional information required by the sample exchanger when a sample is taken out or returned from the sample table during loading / unloading of the sample. For example, a sample table in which samples are arranged vertically and horizontally is indicated by coordinates in the horizontal direction and the vertical direction, and a sample table in which samples are arranged in line is indicated by one of the coordinates in the horizontal direction and the vertical direction. It is preferable that the “sample type” includes all elements that determine appropriate analysis conditions, for example, sample size,
Elements such as sample properties, such as shape or weight, can also be included.

In a preferred embodiment of the present invention, when the operator designates the display of the holding position on which the sample image is superimposed, characters indicating the kind of the sample corresponding to the sample image are displayed. According to this configuration, even when it is difficult to determine the type of the sample only from the sample image composed of figures,
The letter identifies the type of sample. Therefore, the operator can more reliably recognize that there is no input error.

In a preferred embodiment of the present invention, when the type and arrangement of the sample actually held on the sample table are reproduced on the display screen, the analysis of the sample is performed on the same display screen as the display screen. In accordance with the order, an analysis reservation list in which holding positions and types of each sample are listed is displayed. According to this configuration, the analysis reservation list is created and displayed even if the operator does not directly input to the analysis reservation table, so that identification of the sample such as the holding position of each sample on the sample table and the analysis conditions is performed. It is possible to easily input data and analysis work data including an analysis order.

[0014]

Transport means 2 for taking out sample 3 from sample table 21 and transporting it to sample inlet 15 of the fluorescent X-ray analyzer.
4 and a transport control means 23 for controlling the transport means 24. As shown in FIG. 1B, the sample table 21 has a rectangular shape in plan view, and has sample holders 22 at equally spaced positions in the horizontal direction of the arrow X direction and the vertical direction of the arrow Y direction, respectively. The samples 3 can be held side by side on the sample holder 22.

As shown in FIGS. 1 (a), 1 (b) and 1 (c), the transfer means 24 includes an arm 25 for gripping the sample 3, a bar 26 for sliding the arm 25 in the Y direction, and a bar 26.

And a rail 28 for sliding the stand 27 in the direction of the arrow X. The arm 25 can grasp the sample 3 at any position in the X and Y directions and carry it to the sample inlet 15 for analysis.

As described above, since a plurality of samples 3 can be held on the sample table 21, in addition to the analysis samples to be analyzed, standardized samples used for routine analysis routinely performed for quality control, Before analyzing the analysis sample, it is possible to confirm that each composition component is within the standard value, and to hold all samples such as a check sample used for calculating the bias correction value.

The present analysis system also includes a transport control unit 2
The X-ray source 1, the goniometer, the detector 7, etc. of the analyzer 10 are operated in accordance with the analysis conditions according to the set sample type by controlling the sample 3 to carry the sample 3 into and out of the fluorescent X-ray analyzer 10. A control device 30 for performing the analysis of the sample 3 by
A display (display unit) 31 such as a CRT, an input unit 32 including a pointing device such as a mouse, and the following processing unit 40 are provided.

The processing means 40 includes an input screen display control means 4
1, a reproduction screen display control means 42, a character display control means 43, and an analysis reservation list display control means 44.
The input screen display control means 41 displays, on the display screen of the display 31, a plurality of sample images composed of figures corresponding to the types of samples and a holding position diagram indicating a plurality of holding positions on the sample table 21. The reproduction screen display control means 42 selects the specific sample image displayed on the display screen of the display 31 by the input means 32 by the operator, and designates a specific holding position display in the holding position diagram. The selected sample image is superimposed on the designated holding position display, and the type and arrangement of the sample actually held on the sample table 21 are reproduced. When the operator designates the holding position display on which the sample image is superimposed on the display screen of the display device 21 by the input means 32,
Characters indicating the sample type corresponding to the sample image are displayed on the display screen of the display 31. When the kind and arrangement of the sample actually stored on the sample table 31 are reproduced on the display screen, the analysis reservation list display control means 44
On the same display screen as this display screen, an analysis reservation list listing the holding positions and types of each sample is displayed according to the analysis order of the samples.

The processing means 40 also performs processing based on the sample image selected by the operator and the designated holding position display.
For the sample 3 held on the sample table 21, there is provided sample identification data setting means 45 for setting identification data including the holding position on the sample table 21 and the type of the sample in the control device 30.

The processing means 50 further has a kind analysis condition storage means 46. In the X-ray fluorescence analysis, appropriate analysis conditions such as the component (element) to be analyzed, the X-ray fluorescence to be measured, the measurement atmosphere, the order of the calibration curve, and the like differ depending on the type of product to be analyzed. Therefore, the type analysis condition storage means 46 stores in advance appropriate analysis conditions for each type.

The processing means 50 further has a sample identification data storage means 47. This sample identification data storage means 4
Reference numeral 7 stores identification data including the type and the holding position on the sample table for each sample based on the sample image selected by the operator and the designated holding position display. In addition to the stored identification data, analysis work data including the analysis order is set in the control device 30 by the sample identification data setting means 45.

Next, the operation of the present system will be described. First, the operator analyzes an analysis sample to be analyzed by the fluorescent X-ray analysis, and a standardized sample and a check sample.
All the samples required for the automatic operation of the X-ray fluorescence analyzer are placed on the sample table 21 of the sample exchanger.

Prior to the operation of the fluorescent X-ray analyzer, the fluorescent X-ray
A method of an operation performed by an operator while looking at a display screen in order to set analysis operation data necessary for the automatic operation of the line analyzer in the control device 30 will be described with reference to FIGS.

First, as shown in FIG. 2, the input screen display control means 41 causes the display 21 to display the input screen 31a. The input screen 31a displays a window of the analysis reservation input table 50 and, separately, a window of the sample holding diagram 60.

In the analysis reservation input table 50, item columns 51 arranged in a row in the horizontal direction are displayed, and “sequence number” is displayed in the analysis order item column 52 and “position number” is displayed in the holding position item column 53 in order from the left. In the job number item column 54, "job No." is displayed, and in the analysis condition name item column 55, "analysis condition name" is displayed. Below the analysis order item column 52,
The characters “1”, “2”,... Are displayed in order from the top, indicating the analysis order.

Sample holding FIG. 60 shows a plurality of holding positions on the sample table 21 (FIG. 1B), and schematically shows the sample table 21 in plan view. That is, in the sample holding diagram 60 represented by a rectangle of a predetermined color, a plurality of holding position indicators 61 represented by circles of a color different from the background are arranged. These holding position displays 61 are arranged corresponding to the positions of the sample holding portions 22 in FIG. 1B, that is, the holding positions of the samples on the sample table 21, and in the present embodiment, the left and right of the display screen 31a are set. 6 in the direction, 4 in the up and down direction
And the holding position display 61 of a total of 24
1 are arranged in the same manner as the arrangement of the sample holders 22. The sample holding diagram 60 also includes a horizontal coordinate column 62 indicating the horizontal position of the sample table 21 and a vertical coordinate column 63 indicating the vertical position.
"6" and numbers "1" to "4" in the vertical direction are shown.

As described above, the plurality of holding position displays 61
Although the arrangement of the sample holder 22 is accurately reproduced, the shape, size, and the like of the sample holder 22 on the sample table 21 are different.
2 need not be reproduced as it is. For example, the holding position display 61 may have a shape other than a circle.

With the input screen 31a displayed in this manner, as shown in FIG. 3, the operator first sets the analysis order (sequence No.) of the analysis reservation input table 50 according to a predetermined work schedule. The user points the mouse pointer to the job number input field 57 of the identification data input field 56 of “1” and inputs that the analysis is quantitative analysis. Then, the sample type list 70 is displayed on the input screen 31a as a window different from the analysis reservation input table 50 and the sample holding diagram 60. In addition, in addition to the quantitative analysis, the operator can input a qualitative analysis into the job number input field 57.

The sample variety list 70 is composed of a title column 71 indicating a list in the quantitative analysis, a variety name heading column 72 composed of the characters “various name”, and a figure corresponding to the sample type. It is composed of a plurality of sample images 73 and a sample type name character 74 of the sample corresponding to each sample image 73. Such a sample image 73 is registered in advance together with the sample type name character 74 of the sample. The sample image 73 corresponds to the type of the sample. For example, when the sample is a powder, the sample image 73 includes a figure of a container for accommodating the powder sample, and when the sample is a film, a figure of a thin film. in this way,
Since the sample image 73 corresponds to the type of the sample, it also corresponds to an appropriate analysis condition for each type stored in the type analysis condition storage means 46 (FIG. 1A). Although a copper alloy, steel, or the like is displayed as the type name 74, more detailed information on the type of the sample may be registered in advance and displayed on the type list 70 together with the type name.

The operator selects, from the sample type list 70, the type whose analysis order (sequence number) is "1", that is, one type corresponding to the type of the sample to be analyzed first. Specifically, the user operates the mouse to position the pointer, which is the mouse cursor, on the copper alloy sample image 73.
The sample image 73 is selected by clicking a mouse button. Next, the pointer is moved (dragged) while pressing the mouse button, and for example, a holding position display 61a indicating a holding position in which the horizontal direction is 2 (second from left) and the vertical direction is 1 (first from top). Release (drop) the mouse button above to specify a specific holding position indication. Here, the operator performs the operation while remembering the arrangement on the sample table 21 on which all the samples have already been placed, or while looking at the sample table 21. Therefore, a normal operator can immediately specify the holding position display 61 at the correct position.

When such an operation is performed, the reproduction screen display control means 42 (FIG. 1A) moves the copper alloy sample near the center of the holding position display 61a of 2 in the left-right direction and 1 in the up-down direction. The image 73 is superimposed and displayed. As described above, the operator only has to perform an operation similar to the operation of actually placing the sample 3 on the sample table 21 while looking at the display screen 31a, so that the input operation is simple and an input error occurs. Hateful.

When the sample image 73 is displayed over the holding position display 61, the holding position column 5 of the analysis reservation input table 50 is displayed.
8, "2-1" is displayed in the analysis condition name column 59, and "copper alloy" is displayed in the analysis condition name column 59, and the operator does not need to input the holding position or the analysis condition name. Simultaneously with these displays, the identification data including the holding position “2-1” on the sample table 21, the type of sample “copper alloy”, and the fact that the analysis is quantitative analysis are stored in the sample identification data storage means 47. Is done.

Next, the operator points the mouse pointer to the job number input box 88 of the identification data input box 86 whose analysis order (sequence No.) is "2" in the analysis reservation input table 50, and performs the same operation. Perform the operation. In this way, when the operator selects the sample images 73 and displays them over the holding position display 61 for all the samples 3 placed on the sample table 21, the reproduction screen display control means 42 (FIG. 1)
(A)) reproduces the kind and arrangement of the sample actually held on the sample table 21.

When the product type and arrangement are reproduced, all the items are set in the analysis reservation input table 50, and the holding positions and product types of each sample are listed according to the sample analysis order as shown in FIG. The analysis reservation list is completed by the analysis reservation list display control means 44.

Next, the operation for correcting the display screen will be described. By the above-described operation, the operator may want to overlay the specific sample image 73 on the specific holding position display 61, and then move the sample image 73 from the holding position display 61 to another holding position display 61. . In other words, the operator may mistakenly designate the holding position display 61. In this case, the sample image 73 is deleted and the sample image 7 is re-examined from the sample type list 70.
Selecting 3 is time-consuming. Therefore, the operator may select the sample image 73 by pointing the mouse pointer to the sample image 73 in the holding position display 61 erroneously specified and clicking a mouse button. For example, the sample image 73 superimposed on the holding position display 61b in which the horizontal direction is 5 and the vertical direction is 4 in FIG. 4 is selected, and then the pointer is moved (dragged) while holding down the mouse button to move. The mouse button is released (dropped) on the holding position display 61c, which is the holding position display 61 to be made, which is 6 in the left-right direction and 4 in the up-down direction, to designate a specific holding position display. When such an operation is performed, the reproduction screen display control means 42 (FIG. 1)
(A)) is a holding position display 6 in which the horizontal direction is 5 and the vertical direction is 4.
1b, the sample image 73 displayed overlaid thereon is deleted, and the holding position display 61 in which the horizontal direction is 6 and the vertical direction is 4
A sample image 73 of a copper alloy is superimposed and displayed near the center of c.

Further, there is a case where the user wants to erase the sample image 73 on the specific holding position display 61 after the operation causes the specific holding position display 61 to overlap the specific sample image 73. In this case, as shown in FIG.
The mouse pointer is clicked on the sample image 73 in the holding position display 61c and the mouse button is clicked to select the sample image 73. Next, the pointer is moved (dragged) while pressing the mouse button, and the mouse button is released (dropped) on the display screen 31a at the external position in the sample holding diagram 60. By this operation, the sample image 73 superimposed on the specific holding position display 61c is deleted from the screen 31a.

By the above operation, the sample image 73 composed of a figure corresponding to the type of each sample is displayed on the sample holding diagram 60, so that the operator can immediately recognize the type of the sample at each holding position. be able to. However, in the case where the model name cannot be accurately recognized only by the graphic, as shown in FIG. 6, by moving the mouse pointer 33 to the holding position display 61d in which the sample image 73 is superimposed, A balloon 34 is displayed, and the balloon 3
In FIG. 4, characters indicating the type of the sample corresponding to the sample image 73 of the holding position display 61d, for example, characters of “glass” are displayed. Thus, the sample image 7 composed of a figure
Even if it is difficult to determine the type of the sample by using only 3, the type of the sample is clarified by the display of the character “glass”. Therefore, the operator can more reliably recognize that there is no input error.

When the type and arrangement of the sample actually held on the sample table are reproduced, the operator usually next proceeds to
Check for typographical errors. At this time, the sample holding diagram 60
By comparing the actual sample table 21 with the actual sample table 21, an input error can be seen at a glance, and the input error can be easily found. After confirming that there is no input error, the operator operates the display screen 31a.
Select and input the confirm button (not shown) displayed above.

When this confirm button is selected and input, FIG.
The sample identification data setting means 45 shown in (a) sets the analysis work data including the identification data of all the samples stored in the sample identification data storage means 47 and the analysis order in the control device 30.

After the analysis work data is set in the control device 30, the automatic operation of the fluorescent X-ray analyzer 10 starts, and control is performed based on the analysis work data set in the control device 30.

During the automatic operation, an analysis reservation list completed by setting all items in the analysis reservation input table 50 is displayed on the screen of the display. Here, for the sample under analysis, the sequence No. Is displayed in a color different from the surrounding color, so that the operator can recognize that the analysis is being performed.

In this embodiment, the type analysis condition storage means 46 shown in FIG. 1A stores the appropriate analysis conditions for each type.
Analytical conditions may vary depending on the properties of the solid and the like.
In such a case, the kind analysis condition storage means 46 stores appropriate analysis conditions for each kind and property of the sample.
Each sample image 73 may correspond to a kind and a property. As described above, the sample image 73 corresponds to the analysis conditions stored in advance, and can be arbitrarily registered.

[0045]

As described above, according to the present invention, the operator can perform an operation similar to the operation of actually placing a sample on the sample table while looking at the display screen. As described above, the operator does not need to convert the sample holding position in the head into coordinates, which simplifies the input operation and reduces the possibility of input errors. Also, when the operator checks whether there is any input error, the input error can be seen at a glance simply by comparing the type and arrangement of the sample reproduced on the display screen with the actual sample table. Is easy to find.
