Description

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 metal analyzer or an infrared analyzer for irradiating an analysis gas with light to analyze the gas, and a display device of the analyzer.

[0002]

2. Description of the Related Art For example, in an analyzer for analyzing the concentration of gas generated from a metal burned in a furnace, a filter provided in a gas passage is clogged with dust in the gas as the number of analyzes increases. Various situations such as trouble handling and maintenance are required. Informing the user of the analyzer of these situations is extremely important for normal operation of the analyzer. Therefore, as a means for notifying the user of the analyzer of such a situation, for example, when a situation requiring maintenance or a situation causing a trouble occurs, a message requesting maintenance or trouble processing is displayed on the display device. Can be considered.

[0003]

However, if only the maintenance request display and the trouble processing request display are performed as described above, when these displays appear, the user opens the instruction manual and checks the coping method. Therefore, it is necessary to take a countermeasure, and it is troublesome to check a countermeasure. Therefore, the user may be left without performing maintenance and trouble handling, and may proceed to a more serious trouble.

[0004] Therefore, an object of the present invention is to make it possible to easily perform maintenance and trouble handling without having to open an instruction manual and check when maintenance or trouble handling is required for the analyzer.

[0005]

In order to achieve the above object, a display device of an analyzer according to the present invention requires maintenance or trouble handling in an analyzer that irradiates an analysis gas with light. When the maintenance or trouble handling is required based on a predetermined trigger, a window is opened in a part of the display screen to indicate the operation or countermeasure necessary for the maintenance or trouble handling. Characters are displayed by using the formed child window.

In the present invention, "trouble" refers to an abnormality of the apparatus to a certain extent that it is necessary to issue a warning (alarm) to a user. Without it, the abnormal condition may not be noticed. Also, "maintenance or trouble handling" does not mean that there is a clear difference between maintenance and trouble handling,
It does not need to be performed in normal analysis and refers to the processing necessary to obtain normal operation of the analyzer.

As a means for generating a trigger, it is conceivable to use a detector and a counter in addition to a counter and a detector for the number of times of analysis.

According to the present invention, when an abnormality is detected by the detector or when the number of times of analysis reaches a predetermined number, a trigger is generated, and it is displayed on the screen that maintenance and trouble handling are necessary. Operations and countermeasures required for maintenance and troubleshooting are displayed in a child window displayed on a part of the screen. Therefore, the user does not need to open the instruction manual to check these operations and countermeasures, and can perform maintenance and trouble handling quickly and accurately based on the display screen. Further, since the child window is opened and displayed in a large size, the user's awareness of the necessity of maintenance can be improved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a first embodiment of the present invention will be described with reference to the drawings. The analyzer of the present embodiment includes:
As shown in FIG. 1, an analyzer 1 and a microcomputer (hereinafter referred to as “microcomputer”) 2 are provided. Analyzer 1
An electric furnace 3, an infrared gas concentration detector 4, a power supply 5, and a supply power control device 6. The metal is burned in the electric furnace 3, and a combustion gas G generated from the burned metal is supplied to the infrared gas concentration detector 4. And the concentrations of CO ₂ and SO _{2 in} the combustion gas G are detected. The detection signal a output from the infrared gas concentration detector 4 is input to the microcomputer 2. Further, the analyzer 1 has a disconnection detecting sensor 13 for monitoring the resistance of the heater of the temperature controller of the electric furnace 3 and detecting the disconnection.
The disconnection detection signal (resistance value) r from the sensor 13 is input to the microcomputer 2. The interface is not shown.

The microcomputer 2 has a built-in CPU 20, control circuit 21 and memory 22, and is connected to a keyboard 9, a display device 10 and a printer 11. The CPU 20 calculates the element concentration of the impurity in the metal based on the setting data input from the keyboard 9 and stored in the memory 22 and the detection signal a from the infrared gas concentration detector 4, and performs a graphing process. And statistical processing. The calculated element concentration and the like are output to the display device 10 and the printer 11.

The display device 10 displays various set values, analysis results, and the like, displays a message indicating that maintenance or trouble processing is required, and displays an operation or measure required for maintenance or trouble processing. These operations or countermeasures are displayed in a child window B formed by opening a window on a part of the display screen A which is a parent window, as shown in FIG. Here, the “child window” refers to a window that appears in a partial area of the display screen (parent window) A in a window shape, and a frame-shaped critical J appears between itself and the parent window A. In the child window B, for example, as shown in FIG. 3, a schematic configuration of the analyzer 1 is displayed, and a portion E requiring maintenance or trouble processing is displayed by blinking or the like. On the other hand, the message C (D) indicating that maintenance or trouble processing is necessary is, for example, a message shown in FIG.
Is displayed at the corner of the parent window A on which the analysis result and the like are displayed.

The CPU 20 shown in FIG. 1 is provided with an analysis counter 7 for counting the number of analyzes as a trigger for displaying the child window B. Note that the number of analysis times counted by the analysis number counter 7 does not always match the actual number of analysis times. For example, “2” is added in one analysis depending on the analysis target.

Next, an operation of requesting maintenance / trouble processing in the analyzer having the above-described configuration will be described with reference to the flowchart of FIG. When starting in step S1, in step S2, the number of analyzes up to the previous time is
The memory 22 is loaded from an external storage device (not shown). Next, when the analysis of the metal sample is performed in step S3, the analysis number counter 7 is incremented in the next step S4. In the next step S5, it is determined whether or not the count value of the analysis number counter 7 (the number of analysis up to the present) has reached the number corresponding to a preset maintenance request. If the number has not been reached, the process returns to step S3, and the processing up to step S5 is repeated.

If it is determined in step S5 that the number of analyzes has reached the number of maintenance requests, step S6
To the parent window A of the display screen of the display device 6 in FIG.
A message C indicating that maintenance is required is displayed in a corner of the window, a child window B appears so as to open a window on a part of the screen, and maintenance operations and countermeasures are displayed in the child window B. . In step S7 following FIG. 4, it is determined whether or not maintenance has been performed in response to the maintenance request display. If it is determined that the maintenance has been performed, the process proceeds to step S8, and the analysis number counter 7 is reset (cleared to 0). Thereafter, the process returns to step 3 and the processing up to that point is repeated.

If it is determined in step S7 that maintenance has not been performed, the flow advances to step S9 to determine whether the number of analyzes has reached the number corresponding to the trouble processing request. If the number has not been reached, the process returns to step S3, and the processing up to that point is repeated.

If it is determined in step S9 that the number of times of analysis has reached the number corresponding to the trouble processing request, the process proceeds to step S10, where the trouble processing is performed at the corner of the parent window A on the display screen of the display device 6 in FIG. Is displayed, a child window B appears on a part of the screen, and an operation and countermeasure for trouble handling are displayed on the child window B. In step S11 next to FIG. 4, it is determined whether or not trouble processing has been performed in response to the display of the trouble processing request. If it is determined that the trouble process has been performed, the process proceeds to step S12, and after the number of analyzes is cleared to 0, the process returns to step S3, and the processes up to that point are repeated.

FIGS. 5 and 6 show a second embodiment.
As shown in FIG. 5, the analyzer according to the present embodiment has the first
Instead of the trigger from the analysis counter 7 in the embodiment (FIG. 1), the detection signal r of the abnormality detection sensor 13 is used as a trigger in the same manner as in the embodiment shown in FIG. A message C (D) indicating a maintenance request or the like is displayed in a parent window A of the display screen, and a maintenance method or the like is displayed in a child window B.

Next, an operation of requesting maintenance / trouble processing in the analyzer having the above configuration will be described with reference to the flowchart of FIG. When starting in step N1, it is determined in step N2 whether there is a detection signal r from the sensor 13. If it is determined that the detection signal is present, for example, it is determined that maintenance is required, and in the next step N3, it is determined that maintenance is required at the corner of the parent window A on the display screen of the display device 6 in FIG. While the message C is displayed, a child window B appears on a part of the screen, and maintenance operations and countermeasures are displayed on the child window B. Depending on the type of sensor, the detection signal r may be regarded as a request for trouble processing. In this case, in step N3, a message D indicating that trouble processing is required is displayed at the corner of the parent window A of the display screen of the display device 6, and operation and measures for trouble processing are displayed in the child window B. Also, a guideline for preventing the trouble from recurring is displayed.

If the clogging of the filter is detected only by the number of times of analysis, an error easily occurs between the number of times of analysis and the actual clogging state. Accordingly, a third embodiment will be described below as an example of reducing such an error.

FIGS. 7 to 9 show a third embodiment.
As shown in FIG. 7, the analyzer of the present embodiment is provided with a dust detection sensor 12 in the analyzer 1 of the first embodiment (FIG. 1), and detects a detection signal b from the sensor 12 and the number of times of analysis. Using the count value of the counter 7 as a trigger, a message C (D) of a maintenance request or a trouble processing request is displayed on the parent window A of the display screen of the display device 10 as in the first embodiment shown in FIG. Along with
Operations and countermeasures for maintenance and trouble handling are displayed in the child window B. In this case as well, the schematic configuration of the analyzer 1 is displayed in the child window B as in the case of the first embodiment (FIG. 3), and a portion E requiring maintenance or trouble processing is displayed by blinking or the like. .

Next, an operation of requesting maintenance / trouble processing in the analyzer having the above configuration will be described with reference to the flowchart of FIG. Starting at step T1, it is determined at step T2 whether or not there is an abnormality detection signal b from the sensor 12. If it is determined that there is no detection signal, the number-of-analysis counter 7 is reset in the next step T3, the process returns to step T2, and the same process is repeated.

If it is determined in step T2 that a detection signal is present from the sensor 12, the process proceeds to step T4, where it is determined whether or not analysis has been performed. If it is determined that the analysis has not been performed, the process returns to step T2, and the same processing is repeated. If it is determined in step T4 that the analysis has been performed, the process proceeds to step T5, where the number-of-analysis counter 7 is incremented.

In the next step T6, the count value of the number-of-times-of-analysis counter 7 is set to the number m corresponding to the maintenance request.
Whether reached: (N _m -N 9) is determined. If the number has not been reached, the process returns to step T2, and the processing up to step T6 is repeated.

If it is determined in step T6 that the number of analyzes has reached the number of maintenance requests m, step T6 is executed.
Then, it is determined whether the count value of the analysis number counter 7 has reached the number n ( _NT- N: FIG. 9) corresponding to the trouble processing request. If the number has not been reached,
Proceeding to step T8, as in the first embodiment,
A message C (FIG. 2) indicating that maintenance is required is displayed at the corner of the parent window A on the display screen of the display device 6, and a child window B appears on a part of the screen.
After the maintenance operation and countermeasure are displayed in the child window B, the process returns to step T2, and the processing up to step T7 is repeated.

In step T7, when it is determined that the number-of-times-of-analysis counter 7 has reached the number n of trouble processing requests,
Proceeding to step T9, a message D (FIG. 2) indicating that trouble processing is required is displayed at the corner of the parent window A on the display screen of the display device 10, and a child window B appears on a part of the screen. In the child window B, operations and countermeasures for trouble processing are displayed. In the next step T10, it is determined whether or not trouble processing has been performed in response to the display of the trouble processing request. If it is determined that the trouble processing has been performed, the process returns to step T2, and the same processing as before is repeated.

FIG. 9 is a graph showing the correspondence between the symptom of the analyzer and the number of analyzes. The horizontal axis indicates the actual number of analyses, and the vertical axis indicates the symptom of the apparatus. When the sensor 12 is a dust sensor provided in the vicinity of a filter of a flue in an analysis gas passage, at the stage when the sensor 12 starts to detect dust (the number of analyzes: N), no maintenance or trouble processing is performed. The analyzer is still ready for analysis. Therefore, in such a case, after the detection signal b is output from the sensor 12, it is determined in advance how many times analysis is to be performed and maintenance is required, and a symptom requiring trouble processing is obtained in advance. The number of maintenance requests m and the number of trouble processing requests n are set in advance. This makes it possible to know the timing of filter clogging with high accuracy.

In each of the above embodiments, the case of a metal analyzer has been described. However, the present invention can be similarly applied to an infrared analyzer and other non-dispersive gas analyzers.

[0028]

As described above, according to the present invention,
When an abnormality is detected by the detector or the number of analyzes reaches a predetermined number, a message indicating that maintenance or trouble processing is required is displayed on the screen, and a child window that appears on a part of the display screen displays Since operations and countermeasures required for processing are displayed, the user does not need to open the instruction manual to check these operations and countermeasures, and can perform maintenance and trouble handling quickly and accurately based on the display screen. In addition, the user's awareness of the necessity of maintenance can be improved.

According to the present invention, the number of analyzes is counted after the output from the detector is obtained, and when the number of analyzes exceeds a predetermined number, a maintenance request or the like is displayed. Then, as in the case of a dust sensor, if the sensor can sufficiently withstand the analysis even after detection of the sensor, an effective display system can be obtained.
