Abstract

PURPOSE:To display precisely the working state of an equipment by stocking more two kinds of patterns, for which patterns in a contour is made various, selecting the pattern corresponding to a detection signal, and displaying the selected pattern. CONSTITUTION:Coloring parts 3a and 3b are provided inside of the contour of an incinerator 3 and by coloring and displaying these parts, display is executed corresponding to the burning state of the incinerator. Concerning an adjusting valve, in the case of 0% opening, coloring 14 is executed on the inner side of two triangle parts 20 and in the case of 50% opening, coloring 14 is executed only on one triangle part 20. In the case of 100% opening, no coloring is executed to the both triangle parts. Thus, according to the pattern of coloring, the state of each device is displayed in stepwise.

Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a method for displaying equipment operating status.

(Prior Art) In industrial equipment that combines multiple mechanical devices, such as incineration plants, chemical plants, storage and transportation systems, and environmental equipment, monitors are assigned to monitor the operating status of the equipment, and CRT graphic panels are installed. , display the operating status of the device on the printer.

FIG. 14 is a front view showing the operating status of an incineration plant displayed on a graphic panel using a conventional display method;
FIG. 15 is an example of a front view showing a printout sheet 7 similarly printed by a monochrome printer.

In this incineration plant, the incineration system is A.

There are three, B and C, each with an incinerator 3,
It is assumed that each incinerator 3 is connected to an exhaust blower 5 via a control valve 4, and the exhaust blower 5 exhausts combustion gas from the incinerator 3, collects it in an exhaust tower 6, and discharges it.

Then, when going to the system, the incinerator is stopped, the control valve is closed, and the exhaust blower is stopped. On the system side, the incinerator is operated at a medium capacity, the control valve is opened to 50%, and the exhaust blower is also opened to 50%. driving with the ability of In System C, the incineration capacity is further increased and the incinerator is operated at full capacity.
It is assumed that the control valve is 100% open and the exhaust blower is also operating at 100% capacity.

In an incineration plant, it is necessary to monitor the operating status of each system, so screen 2 of graphic panel 1
The operating status of the incinerator control valve, blower, etc. is displayed.

However, in the conventional display method, for example, exhaust blower 5 simply indicates the presence of the exhaust blower.

(Problem to be Solved by the Invention) However, in this case, the open state and closed state of the control valve 4 cannot be intuitively understood. Furthermore, it is not possible to intuitively distinguish between the stopped state and the operating state of the exhaust blower, and there is no way of knowing at what capacity the exhaust blower is being operated. Moreover, when printed on a monochrome printer as shown in Fig. 15, the inside of the contour 4 of the control valve and the contour 5 of the exhaust blower will be almost the same black part 16 whether in the stopped state or in the operating state, and the operating state can be determined. Can not.

Furthermore, since color printers are not very popular, monochrome printers are advantageous because they have new drawbacks such as high equipment cost, slow printing speed, and high running costs.

The problem of the present invention is to determine the operating status of each device in stages.
To provide a method for displaying equipment operating states that can clearly distinguish and display intermediate operating states, stopped states, and full operating states, and that can be intuitively understood by a supervisor at a glance.

(Means for Solving the Problems) The present invention stores in advance two or more types of iconographic display patterns having at least different patterns in the outline corresponding to the operating state of the equipment, detects the operating state of the equipment, The present invention relates to a method for displaying an operating state of an apparatus, in which one of the iconographic display patterns is selected based on a detection signal, and the selected pattern is displayed on a display medium.

Further, the present invention stores in advance two or more types of iconographic display patterns having at least different contours corresponding to the operating state of the equipment, detects the operating state of the equipment, and based on this detection signal, the iconographic display patterns The present invention relates to a method of displaying the operating state of a device by selecting one of them and displaying the selected pattern on a display medium.

"Equipment" includes various equipment such as valves, blowers, tanks, furnaces, etc., and "operating state" refers to valve opening, flow rate, etc.
This includes the air volume of the blower, the electric power, the rotation speed of the motor, the amount of water stored in the tank (storage amount), the temperature and pressure of the incinerator, reactor, etc. "Storage" refers to storing something in a memory or the like.

The "operating state of the equipment" is detected by a pressure sensor, a flow rate sensor, a temperature sensor, etc. depending on the nature of the equipment. Examples of "display media" include CRT screens, liquid crystal displays, printed matter output from various printers, projection screens, etc., and "display" includes such images, printing, and projection.

"Iconographic display pattern" refers to a pattern that is not letters or numbers.

"Outline" refers to a line drawing, etc. that constitutes the outer shape of an iconographic display pattern, and "pattern within the outline" refers to a pattern inside the outline, such as a pattern, pattern, line drawing, color coding, gradation, etc.

(Example) Fig. 1 is a front view similar to Fig. 14 showing an image displayed on a graphic display according to the display method of the embodiment of the present invention, and Fig. 2 is a front view showing an image similarly printed by a monochrome printer. It is a diagram. Each system of the incineration plant A, B,
The operating state of C is similar to that shown in FIG. That is, in system A, the incinerator is stopped, the control valve is closed,
The exhaust blower was stopped, and on the system side, the incinerator was operated at a medium capacity, the control valve was opened to 50%, and the exhaust blower was also operated at 50% capacity. In system C, the incineration capacity is further increased, the incinerator is operated at full capacity, the control valve is 100% open, and the exhaust blower is also operated at 100% capacity.

This example is characterized in that colored parts 3a and 3b (for example, colored red) are provided inside the outline of the incinerator 3 (for example, the outline is green). That is, in system A, the colored part is not colored, in system A, the colored part 3a of a predetermined size is colored, and in system C, both colored parts 3a and 3b are colored. This allows the user to intuitively understand the combustion state of the incinerator.

In addition, regarding the control valves of each system, in the case of system A that is 0% open, the inside of the two triangular parts 20 is colored 14 (for example, red), and in the case of system B that is 50% open, one of the triangles is painted. Only part 20 is colored 14, and the other triangular part 20 is left blank 15 (i.e., only the outline is green), and 100
In the case of the % open system C, the inside of both triangular parts 20 is made into a blank space 15.

Similarly, for the exhaust blower of each system, in the case of system A, the inside of the blower outline 5 is colored 14 (for example, red).
In the case of system B, coloring 14 is applied to only about half of the inside of the blower, and in the case of system C, coloring 14 is not applied to the inside of the blower and blank 15 (i.e., only the green outline) is applied. shall be.

When displaying, as conceptually shown in Figure 3, each system A, B, Ci, [all equipment 9A, 9B, 9C]
(corresponding to the incinerator, control valve, and blower) sends information such as temperature, valve opening, air volume, and power amount to the information processing unit 8 as electrical signals. The information processing unit 8 stores in advance each display pattern shown in FIG. 1, and selects a corresponding pattern from among the stored display patterns according to the electrical signal input to the image processing unit 8. Blower air volume 45~5
In the range of 5%, the pattern is selected by assuming that the air volume is 50%. ), this selected pattern is sent to the graphic panel 1 and displayed on the screen 2. Further, the same selection pattern is sent to the monochrome printer 7, and printing is performed.

When selecting an image display pattern, the display pattern selector 8a first selects a corresponding pattern, and based on this, the color information pattern generator 8b and the shape information pattern generator 8c generate necessary electrical signals, which are then transferred to the CRT. send to

According to the display method of this embodiment, the operating status of the incinerator and the opening degree of the control valve can be displayed in stages (for example, 0% operation, 50% operation,
It can be displayed in three stages (100% operation), making it possible to accurately grasp the operating status of each system. What's more, you can see the temperature inside the furnace at a glance by displaying it on the graphic panel, you can quickly understand the operating capacity, and you can also check the opening of the control valve at a glance. I understand.

This allows you to move on to the next screen without wasting time, which greatly reduces monitoring effort, and abnormalities are difficult to overlook and can be discovered quickly.

Furthermore, when outputting from a monochrome printer as shown in FIG. 2, the inside of the colored parts 3a and 3b will be printed as a black part 16, and the inside of the triangular part 20 of the control valve will also be colored as a black part 16. Since the printed paper 7 is printed in a manner similar to the above, there is no risk of confusing the operating states, and the operating states can be understood at a glance in the same manner as described above.

Further, if the color tone of the colored part is a control valve, for example, it will be easier to distinguish on the graphic panel if the color tone of the colored part is changed to purple, blue, green, orange, light, etc. depending on the opening degree of the control valve.

In the above example, the present invention was applied to displaying the operating status of a control valve, an incinerator, and a blower, but the present invention can of course be applied to other equipment.

As shown in FIGS. 4 to 6, in the above embodiment, the operating state of the control valve is displayed in five stages, but it can also be displayed in three stages.

In the example shown in FIG. 4, the size of the colored portion 14 is associated with the opening degree of the control valve, and by dividing the size of the colored portion 14 into four stages, the opening degree is 25%, 50%, and 75%, respectively.
, 100% is displayed. At this time, only the outline 4 can be displayed in green, for example, and the colored part 14 can be made red (of course, the reverse is also possible), or the outline 4 and the colored part 14 can be made the same color. It is considered that it is visually clearer if the colored part and the outline are different in color.

In addition, as shown in Fig. 5, by inserting vertical lines 17 within 2 degrees of one triangular part and increasing the number of vertical lines 17, the opening states of 25%, 50%, 75%, and 100% can be adjusted. can be displayed.

Furthermore, as shown in FIG. 6, by combining FIG. 4 and FIG. 5, when the opening degree is 25%, 50%, 75%, and 100%, the right triangular portion 20 is colored, and the left triangular portion is colored. Vertical lines 17 may be inserted within the opening 20, and the degree of opening may be distinguished by the number of vertical lines 17.

Furthermore, in each of the above cases, the outline of the image display pattern remains the same and the pattern inside the outline is changed, but it is also effective to change the outline itself, as shown in Figures 7 to 9. be.

That is, FIG. 7 shows an example in which the contour of the control valve gradually becomes smaller depending on the opening degree, and when the opening degree is 50%, the size of the contour 4A (i.e., the triangular part 20A, the vertical line part 30A) is reduced, and when the opening degree is 0
%, contour 4B (i.e. triangular part 20B, vertical line part 30B
) The opening degree can also be distinguished by further reducing the size of the opening. In addition, coloring 14 is applied depending on the opening degree. In this way, it is thought that changing the outline of the display pattern itself will make it even easier to see, and combining coloring will further enhance the effect.

Further, as shown in FIG. 8, at the opening degree of 50%, only the triangular part 2OA on the right side of the outline 4C is reduced and colored 14,
When the opening degree is 0%, both triangular parts 2OA of the outline 40 are reduced and colored 14 to distinguish them.

Furthermore, as shown in Figure 9, at 100% opening, the contour 4E
By lengthening the vertical bar portion 30C of the contour 4F and shortening the vertical bar portion 30B of the outline 4F when the opening degree is 0%, the opening degrees can be distinguished from each other by the lengths of the vertical bars B30.30C and 30B.

At this time, when combined with the change in coloring 14, it becomes even easier to see as in FIG.

It is also possible to combine the display methods shown in FIGS. 4 to 9 with each other. For example, combining a change in the outline, a change in the outline size and a change in the number of vertical lines 17, a combination of a change in the outline and a change in the colored area, a combination of a change in the outline and a change in the color to be painted. It is possible to combine changes in colored area and changes in color, etc., and by employing such a combination, it is also possible to display extremely minute changes as symbols.

10 to 13 each show an example of an exhaust blower to which the method of the present invention is applied.

In the example shown in Fig. 10, the inside of the outline 5 is blank 15 when it is in full operation (100% capacity), and the colored part 14 is provided on the right side of the outline 5 when it is operating at 50% capacity, and when it is stopped (0% In the ability) state, the entire outline 5 is colored to distinguish it. In this way, by changing the coloring pattern within the outline 5, the air volume of the exhaust blower can be displayed.

Furthermore, in addition to this, power usage can be displayed based on size, and colors can be combined with patterns to display the display method shown in FIG. 11. That is, colored part 1
The air volume of the exhaust blower is displayed according to the proportion occupied in the contours 5.5A and 5B of 4, and the decrease in electric power is expressed by reducing the size of the contours 5.5A and 5B.

Furthermore, as shown in FIG. 12, two display formats for the case of operation at 50% capacity can be stored in advance, and separate meanings can be assigned to each display format.

In other words, the displayed pattern on the left shows the case where the damper restricts the air flow at the current rating, and the displayed pattern on the right shows that
This represents the case where the damper is used to restrict air flow below the current rating.

Furthermore, it can be said that the aid of a special contour in which a characteristic display medium such as a scale is added to a normal contour makes it very easy to understand. For example, as shown in Fig. 13, a scale display 25 is attached in the full operating state, and a contour 5C is attached when operating at 50% capacity.
Shorten the scale display 25A by slightly shortening the right side of the contour 5D, and further shorten the right side of the contour 5D when stopping to shorten the scale display 25B.
They may be distinguished from each other by making them shorter.

(Effects of the Invention) According to the method for displaying the operating state of equipment according to the first invention, two or more types of display patterns having at least different patterns within the outline are stored in advance corresponding to the operating state, and based on the detection signal, Since one of the display patterns is selected and this selected pattern is displayed on a display medium such as a CRT or graphic panel, it is possible to display in two or more stages, making it possible to precisely display the operating status. becomes. Furthermore, since the iconographic display pattern is displayed, each operating state of two or more stages can be understood at a glance, processing can be done in a short time, the labor of monitoring can be reduced, and abnormal parts can be easily discovered.

Even when the results are printed on a monochrome printer, it is possible to determine the operating status of the device, and compared to color printers, the device price is low, the printing speed is high, and the printing speed is fast. For this reason, its utility value is extremely large.

In addition, if there are three or more types of storage display patterns,
Since a stepwise display of three or more stages is possible, even intermediate states can be displayed, and the calendar display becomes more precise, making management and situation judgment easier.

Also, according to the method for displaying the operating state of equipment according to the second invention, two or more types of display patterns having at least different contours are stored in advance corresponding to the operating state, and one of the display patterns is selected based on the detection signal. Since the selection pattern is selected and this selection pattern is displayed on the display medium, it is possible to perform stepwise display in two or more stages, and the same effect as the first invention can be achieved.
