Was manual work. There has been a demand for mechanization by using an electronic computer for this work. However, in the data processing of each device that constitutes the system required for computer processing, the Atomic Energy Society of Japan "Journal of the Atomic Energy Society" (1990 Vol.32 No.2), page 58, item 3 (1) and As shown in Fig. 3 on page 60, in addition to the need for tree structure data for associating devices with each other, the required amount is the same as on page 60 (3) Knowledge Base Scale. It will be huge as in. Further, it has not been realized as a practical device due to the fact that it takes time to process these main structure data.

FIG. 9 shows a part of a system diagram of a liquid such as water as an example of a fluid system for performing the treatment in the conventional method and the present apparatus. The present invention is to automatically diagnose a region (bold portion) formed by the black (showing a closed state) valve shown in the drawing.

The conventional method is to register all devices constituting a system as independent data for each device in a computer as a means for performing the above diagnosis, and further associate the data comrades of each device with each other using a tree structure. Had adopted. Specifically, as shown in the example of how to hold data shown in FIG. 10, the device 1 is associated with the valves 2 to 5, and the valve 4 is associated with the device 1 and the valves 2 to 6. When the diagnostic processing is executed, the data of related valves (open / closed state, etc.) around the device designated as the starting point is “closed”, that is, to the point where the fluid flow path is blocked in sequence. The judgment is made.

The above conventional method requires enormous amount of data to be registered in an actual plant where hundreds of pipes are branched from one device, processing time is significantly increased, and erroneous input of association data causes a diagnosis result. Since there is an essential problem that it has a significant influence, there was a major technical problem in making it a practical device.

Further, FIG. 11 shows the opening / closing state of each opening / closing device for isolating the valve 4 from the entire system when the valve 4 in the system diagram is disassembled and inspected.

In the conventional method, similarly, data associated with each other using a tree structure is processed, and the valve closest to the device designated as the starting point is sequentially searched for. However, the conventional method requires an enormous amount of data to be registered and requires a long processing time, and there is an essential problem that an erroneous input of association data seriously affects the diagnosis result.

An object of the present invention is to accurately and rapidly flow a fluid path in a system,

[Action]

 The operation of the above configuration will be described below.

One point on the system diagram displayed as a graphic image on the computer screen is arbitrarily designated, and the designated point can be colored with an arbitrary color using the background color of the screen as a boundary surface. Further, the coloring process is mechanically performed on the entire range where the dots are continuous in the vertical or horizontal direction in the computer.

When this processing is performed, visually, the situation where the fluid flows out into the system centering on the specified equipment, piping, etc. on the system diagram displayed on the image is displayed very rapidly as the coloring effect of the system diagram. Will be. This outflow (coloring) action is performed up to the point where the continuity of the dots that make up the image is interrupted (fluid end point), so the outflow range and route of the fluid are automatically diagnosed and the nearest device The switchgear can be automatically extracted.

Furthermore, by displaying or erasing the dots that display the connection with the pipe or the like in accordance with the open / closed state of the opening / closing device such as the valve, it is possible to control the colored display range (fluid outflow range). Therefore, it is possible to freely configure the system and simultaneously diagnose the area.

As described above, the present apparatus operates as a simple coloring process inside the computer without performing a search process for individually registered tree-structured data as in the related art, and thus accurate and high-speed processing is possible. Furthermore, since the data mainly consists of the graphic image display data, it is possible to process with an extremely small amount of data as compared with the conventional method.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings. still,
The same reference numerals are given to the same structural parts as those of the conventional example, and the description thereof will be omitted.

FIG. 1 is a block diagram showing the basic structure of the fluid flow path diagnostic apparatus of the present invention, in which 12 is a computer main body, 13 is a display, 14 is a printer, 15 is a color copy, 16 is a bar code generator, and 17 is 3 shows a bar code reader. The type of electronic computer and language is not particularly limited as long as the following graphic image processing is possible.

The basic operation principle of this device will be described below with reference to the system diagram shown in FIG. The computer language used for the explanation is the most general BASIC language.

The basic data processing of this device is coloring processing for the graphic image itself, but the method is performed by a concept opposite to general coloring processing.

FIG. 2 shows the concept of a general coloring method. In the coloring processing, the point 19 in the coloring area frame 18 is used as a starting point and the inside of the coloring area 18 is filled with a designated color in the coloring direction 20. By. PAI is an example of instructions in the BASIC language
There are NT (X, Y), COLORI, COLORII. Here, X and Y are the coordinates of the coloring start point 19, COLORI is the color to be colored, and COLORII is the color of the colored region frame 18.

FIG. 3 shows the basic concept of the coloring processing method of this device, and the coloring processing constitutes the colored area frame 18 itself.
This is done by filling the area frame 18 itself with a designated color starting from. PAINT (X, Y), COLORI, and COLORII, which are the same as those used in the conventional method, are used as command examples in the BASIC language. However, in this case, X and Y are part of the coordinates of the dots forming the area frame 18, and COLORII is not the color of the colored area frame 18 but the background color 22 of the screen itself. COLORI is
It is the color to be colored. In the above basic concept, if the line segment showing the colored region frame is assumed as a part of the piping etc. on the fluid system diagram, the coloring process will cause the fluid to flow out from one point on the system diagram to the range where the piping etc. are connected. The range to be displayed is colored.

FIG. 4 shows an example of a dot display state when a part of FIG. 9 is displayed as a graphic image. With this device, in addition to the coloring of these dots, by displaying or erasing a part of the dots that display the opening / closing device and the pipes connected to it in accordance with the opening / closing operation data of the opening / closing device such as a valve. Controls image continuity or discontinuity.

That is, the valve 4 in the open state displays the dots 23 and 24, and the valve 6 in the closed state erases the dots 26 and 27, that is, the same color as the background color. In FIG. 3, when the coloring process is performed with a part of the device 1 as a starting point, the coloring process proceeds to the dot 25 where the dots become discontinuous and stops.

In this state, it is judged that the flow path is blocked by the closed valve 6, and this device functions as a diagnostic device. In the case of the check valve 3, the dots 28 and 29 are erased in advance, and then the system is colored to make a determination that combines the coloring status of the dots 30 and 31 and the operating direction of the valve itself to make a check valve. Can be performed on the image.

That is, if there is a color difference between the dots 30 and 31, it is determined that the fluid is flowing to one of the valves, and the dot 27
If the side is colored, it is judged to be the forward direction and dots 28 and 29 are displayed to continue the coloring process.If the dot 30 side is colored, it is judged to be the reverse direction and the dots are left and the coloring process is performed. Can be stopped. In FIG. 4, when the device 1 is colored as a starting point, the coloring is in the opposite direction, and the coloring is stopped at the portion of the dot 30.

Next, a basic method for extracting the valve to be closed so as to isolate the valve 4 from the entire system will be described with reference to FIG. FIG. 6 shows an outline of the processing procedure. As a processing condition, after temporarily forcibly closing all the valves, that is, after erasing the dots between the valves and the piping section,
Coloring is performed starting from the part to be isolated. The coloring is performed on the system diagram up to the portion where the dots are discontinuous, that is, the portion where the dots are erased by the forced closing operation and then stopped. After the coloring is stopped, it is possible to determine the color of the pipe portion connected to both ends of each valve, and if there is a difference, it can be determined that the valve functions as an isolation valve.

FIG. 5 is a schematic diagram showing the procedure of the fluid flow path diagnosis processing according to the principle of the present embodiment. As shown in the procedure of FIG. 5, the present apparatus utilizes the high speed and accuracy that the coloring process is instantaneously performed as the physical process of the computer itself, and the data to be subjected to the determination process is the graphic image itself. These are the dots that make up the system and take advantage of the fact that there is no need to register the enormous amount of data associated with each device as in the past, and the bar code output of the open / closed state of each valve and the color hard copy output function of the system diagram etc. This is a combined fluid flow path diagnostic device.

In this way, this device does not use the method of order determination processing of individually registered data, which is a conventional basic problem,
A fluid flow path diagram (for example, a piping system diagram such as that shown in FIG. 7) is displayed as a graphic image on the display screen of an electronic computer, and processing that focuses on the continuity of each dot that is a display element of the image is performed. That is the solution.

That is, in the case where dots that display graphics, line segments, and the like of a graphic image are adjacent to each other in at least one of the upper, lower, left, and right directions, mutual dots are considered to be continuous in image data processing. By replacing the continuity of the dots with the flow of the fluid, it is possible to perform the fluid flow path diagnosis, which is a problem of this device as physical processing in the computer rather than the conventional data processing concept, at extremely high speed and accuracy. .

Furthermore, the operation of opening / closing devices such as valves and switches that determine the flow path of the fluid is replaced by displaying or erasing a part of the dots displaying them to control the continuity of the actual fluid. It can be processed in the computer in a state very close to the operation.

Although FIG. 8 is an electrical wiring system diagram, according to the apparatus of this embodiment, the electrical wiring can be diagnosed in addition to the above-described fluid channel diagnosis. In addition, it becomes possible to manage the system of various systems such as information.

〔The invention's effect〕

According to the present invention, it is possible to mechanize the system configuration planning work, the system configuration result diagnosis, and the system configuration diagram creation work in which the isolation range is colored by only registering a small amount of data, which can be done only by manual work in the past, and at high speed. In addition, since accurate processing can be performed, it is possible to greatly improve the efficiency and accuracy of work. Further, by using the bar code, it is possible to efficiently perform the work of registering the opening / closing operation result of the valve or the like in the computer, and it is possible to improve the work management efficiency.
