Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plant information display device, and more particularly to a plant information display device capable of promptly extracting only information required by a user.

[0002]

2. Description of the Related Art Generally, in operating a complex process plant such as a nuclear power plant, it is necessary to refer to design information as necessary. As the design information, a pipe instrumentation diagram (P & ID) that represents piping, valves, pumps, instrumentation equipment, etc. as a drawing, an interlock block diagram (IBD) that represents the interlocking logic of
There is a single line connection etc. showing the configuration of the power supply system, which is expressed as a drawing. However, since the structure of a nuclear power plant is complicated, these documents range from hundreds to thousands of pages, and it is not easy to quickly obtain necessary information.

Further, when these pieces of information are referred to during the operation of the plant, there is a demand for superimposing them on the process data of the operating plant. For example, it is a case where the configuration of the pipe, the operating state of the pump, the open / closed state of the valve, the pressure of the pipe, the flow rate, etc. are simultaneously referred to. In such a case, it is a burden on the operator to refer to the design information written on the paper and the process data displayed on the instrument.

In order to solve the above problems, a display device using a CRT monitor driven by a computer has been conventionally developed, and a mimic or the like showing the configuration of piping is displayed together with plant process data by button operation. These display devices display process data of the plant, such as the operating state of the pump, the open / closed state of the valve, the flow rate of the pipe, and the pressure, as well as the P & ID indicating the outline of the pipe of the plant.

By using such a display device, the main configuration of the plant and the process data can be provided to the plant operator in a format that is easy to understand.

[0006]

However, the conventional display device has an original purpose of displaying process data, and is not sufficient as a function of providing design information.

On the other hand, in the case of the CAD system for the purpose of design, it goes without saying that the P & ID and IBD of the complete plant can be displayed on the CRT monitor. However, the display function of these CAD systems is originally intended to edit the drawing for printing on paper, and there is a problem in using it for the operation of the plant as it is.

FIG. 7 shows P in the conventional CAD system.
& Part of ID. This is a drawing of a part of one sheet of P & ID, and it is about 1/100 of the entire sheet in area.
Corresponds to the part. In FIG. 7, reference numerals 11a and 11
b and 11c are pipes, reference numeral 12 is a valve, and reference numeral 13 is a pipe 11.
a is attached information, reference numeral 14 is attached information of the valve 12, reference numeral 15
Reference characters a, 15b, 15c, and 15d represent information on the instrumentation system.

As is clear from FIG. 7, since the density of P & ID information is quite high, there are the following problems.
In other words, even a high-resolution CRT monitor device is 1200
Since the resolution is about 1000 pixels, when displaying the entire P & ID drawn on one sheet as a design document, there is a problem that the details are crushed, and when the details are displayed so that they can be seen completely. Has the problem of not being able to see the whole thing.

Further, even if an ultra-high resolution display device capable of displaying the entire surface of one P & ID without crushing details can be used, the amount of information displayed on one screen becomes enormous. Therefore, there is a problem that it takes a lot of time and labor to find out necessary information.

In order to solve this, it is conceivable that a design drawing having a large amount of information is divided into a plurality of drawings so as to have an appropriate amount of information and displayed, but the drawing is represented by one sheet. In order to properly divide into a plurality of sheets, it is necessary to devise a layout or the like, which cannot be done mechanically. Therefore, there is a problem that the cost of creating the database is high and it is not easy to reflect the design change promptly.

The present invention has been made in consideration of such a point. Even if the amount of information on a single base drawing is large, only the information required by the user can be quickly extracted and displayed. An object is to provide a plant information display device that can be displayed on the device.

[0013]

As a means for achieving the above object, the present invention classifies screens for expressing design information of a plant according to the type of information, and displays graphics and characters representing the design information. Display screen database that records as graphic data separately in layers that overlap on a plane according to the classification to which each belongs; process data input device that inputs plant process data in real time; request input that inputs requests from users A device; a video memory for storing a bitmap image for representing a screen; and a graphic data belonging to a layer of required design information based on a request from the request input device, taken out from the display screen database. , If graphic data refers to process data, the corresponding process data A display control device for inputting them from the process data input device and developing them as bit map images on the video memory; and a display device for displaying the bit map images developed on the video memory; Characterize.

[0014]

In the plant information display device according to the present invention,
The screen for expressing the plant design information is classified according to the type of information, and the figures and characters that represent the design information are displayed as graphic data by dividing them into layers that overlap on a plane according to the classification to which they belong. It is recorded in the screen database. Then, when the user inputs a screen to be displayed and a request regarding the layer from the request input device, a screen corresponding to the request is displayed on the display device.

Further, at this time, when referring to the process data, the corresponding process data is taken out from the process data input device and displayed together with the graphic data.
Therefore, even if there is a large amount of information on one base drawing, only the type of information requested by the user can be displayed, and the necessary information can be retrieved quickly.

Further, since dividing the information on the design drawing by an appropriate classification standard is almost a mechanical operation, the display screen database can be easily generated from the design drawing, and the cost can be kept low. Becomes

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The plant information display device according to the present invention will be described below by taking the case of displaying P & ID as an example.

FIG. 1 is an overall configuration diagram showing an example of a plant information display device according to the present invention. This device includes a display screen database 1, a process data input device 2, a request input device 3, and a video memory. 4 and display control device 5
And a display device 6.

In the display screen database 1, graphics and characters representing design information to be displayed are stored as graphics data.
It is divided into layers and stored according to the type of information.

2 to 4 show the case where the P & ID shown in FIG. 7 is decomposed into layers. That is, FIG. 2 is a layer showing main pipes and valves and their associated information in the P & ID shown in FIG. 7. See also FIG.
Of the P & ID shown in FIG. 7 is a layer representing information attached to piping and valves.

The graphic data includes an identifier, a layer identifier,
It consists of coordinates, shape identifiers, and attributes. As an example, the format of piping, valves, and attached information of piping is shown below. [Data 1] [F1, (L1), (400, 220), PIPE,
{((784, 220)), THICK, F3}] [F2, (L1), (440, 220), VALVE,
{LARGE, CLOSE, F1, F22}] [F3, (L2), (405, 195), PIPE-A
TTRIBUTE, {"1A-300A-RHR-1
5 ″}] One line corresponds to one figure in the data 1. In the data 1, F1, F2, and F3 are figure identifiers and are used to distinguish the figures on the display screen database 1 from each other. In addition, L1 and L2 in the data 1 are layer identifiers and indicate the layer to which each figure data belongs.If the same figure appears in different layers as shown in FIGS. Attach multiple layer identifiers to one figure data.In particular, when displaying process data, record different figure data corresponding to the same process data in different layers, and perform the expansion procedure to bitmap respectively. By changing, the expression of process data can be changed for each layer.

Coordinate data is described after the identifier of the layer identifier, and the position occupied by the figure on the drawing is recorded. A shape identifier for indicating the shape of the graphic is placed after the coordinates. PIPE, VALVE, PIPE-
ATTRIBUTE is a shape identifier, and determines the format of the figure drawn in the drawing.

Finally, attached information is placed. The attached information is recorded in a different format depending on the shape identifier. When the shape identifier is PIPE, the coordinate data representing the shape of the pipe, the thickness on the drawing, and the graphic identifier representing the attribute information of the pipe are the additional information. In the example of data 1,
((784, 220)) indicates the shape of the pipe, THICK indicates that it is drawn thick, and F3 indicates that the attribute information of the pipe is described in the graphic data F3. When the shape identifier is VALVE, the attached information is the size of the symbol of the valve drawn, whether the symbol is open or closed, the graphic identifier of the pipe to which the valve is connected, and the attribute information (the graphic representing the type and number of the pipe). is there. Here, F1 is a graphic identifier of the connected pipe, and F22 is a graphic identifier representing attribute information. When the shape identifier is PIPE-ATTRIBUTE, a character string drawn as the attribute information of the pipe is recorded. In the example of data 1, "1A-300A-RHR-1"
It is 5 ".

Further, when displaying the plant process data on the display screen, graphic data for displaying the process data is recorded in advance. The data in this format is composed of a graphic identifier, coordinate data, a shape identifier indicating that it is process data, and a process data identifier as attached information. An example is shown below. [Data 2] [F4, L1, (415, 205), PA, PA110
5] In the data 2, PA refers to process data whose graphic data represents numerical data, and the process data identifier PA
1105 shows that an actual value can be input.

Various display methods can be considered for the process data such as the flow rate of the pipe. For example, digital numerical values and bar charts. The display method can be changed by describing a conversion procedure (that is, a program) into a bitmap image that can be interpreted by the display control device 5 described later in the above-mentioned attached information part.

The display screen database 1 records these graphic data for each display screen in the display order. When an inquiry about the display screen is received from the outside, the graphic data belonging to the inquired display screen is displayed in the display order. Align and output. The display order is the order in which the graphic data is converted into the bitmap image, and by maintaining this, the developed bitmap images are always the same even when there are overlapping graphics.

The process data input device 2 is adapted to input process data of a plant in real time,
The input data is temporarily stored in a format that can be referred to by the process data identifier.

The request input device 3 is adapted to input a drawing display request from a user. Specifically, a display screen to be displayed and a layer to be displayed are input as requests. It is like this.

The video memory 4 is adapted to record a bitmap image of a display screen developed by the display control device 5 which will be described later, and the display control device 5 is designated by the request input device 3. The display screen and the graphic data of the layers are taken out from the display screen database 1, the process data is input from the process data input device 2 as necessary, and these are expanded as a bitmap image on the video memory 4. There is. The display device 6 is composed of, for example, a CRT monitor, and displays the bitmap image developed on the video memory 4 as a screen image.

FIG. 5 is a flow chart showing the details of the processing in the display control device 5, and the operation of this embodiment will be described below with reference to FIG.

First, in step S21, the identifier of the screen to be displayed and the set of the identifiers of the layers to be displayed are input from the request input device 3 and substituted into variables D and L, respectively. Since there are generally a plurality of layers to be displayed, they are input as a set.

Next, in step S22, the display screen database 1 is searched using the screen identifier D as a search key, and the graphic data belonging to D is extracted. The extracted graphic data is assigned to the queue referenced by the variable S. The graphic data has the display order as described above, and in order to maintain this, the queue S has the first-
The in / first-out key.

Then, in step S23, the first element is extracted from the queue S and is substituted into the temporary variable x. That is, the graphic data is extracted according to the display order. In addition,
The fetched element is deleted from the queue S.

Then, in step S24, x is n
It is determined whether or not it is il. nil is a special element that is taken out when the queue S is empty, and when x is nil, it means the end of the graphic data to be displayed. Therefore, in this case, the processing ends. On the other hand, if not, the process proceeds to step S25 to check the layer identifier of x. If the layer identifier does not belong to the set L, x is ignored and the process returns to step S23. If the layer identifier belongs to the set L, the process proceeds to step 26.

In step S26, the shape identifier of x is examined to determine whether or not to refer to the process data. If it is necessary to refer to the process data, the process proceeds to step S27. If it is not necessary to refer to the process data, the process jumps to step S27 and proceeds to step S28.

In step S27, corresponding process data is input from the process data input device 2 according to the process data identifier of x. Also, step S
At 28, the bitmap image is developed on the video memory 4 according to the coordinate of x, the shape identifier, and the attached information. Then, after that, the process returns to step S23 to repeat the above process, and finally the screen image is developed on the video memory 4.

As described above, according to this embodiment, only the information required by the user is displayed, so that the user can quickly retrieve the required information.

In step S25 of FIG. 5, when it is checked whether or not the layer identifier of the graphic data belongs to the layer L, if the layer identifier is represented by a specific bit on the bit vector, this identification is performed for each bit. AND to
This can be done by performing an operation and checking whether or not there are any bits that are ON. In general, a digital computer can perform this kind of bit operation at high speed, and therefore can speed up this process.

In the above embodiment, the case where the display screen database 1 records graphic data in display screen units has been described. However, while the function of the display screen database 1 is recorded in display screen layers, The processing of the display control device 5 may be changed as shown in the flowchart of FIG. As a result, the processing height can be improved.

That is, first, in step S31,
The display screen and the set of layers are input from the request input device 3 and substituted into variables D and L, respectively. The variable L is firsts
It is a t-in / first-out queue, and elements can be fetched one by one.

Then, in step S32, the variable L
The first layer is extracted from and is assigned to the variable l, and it is determined in step S33 whether l is nil. nil is a special element that is taken out when the variable L becomes empty. If l is nil, the process ends, otherwise the process proceeds to step S34.

In step S34, the graphic data belonging to the layer 1 of the display screen D is fetched from the display screen database 1 in the display order and substituted into the variable S.
S is the first-in / first-out queue.

Next, in step S35, the top element is extracted from S and substituted for the variable x, and in step S36, it is determined whether x is nil. If x is nil, step S3
Returning to step 2, the process for the next layer is performed. If x is not nil, it is determined in step S37 whether or not the shape identifier of x refers to the process data.

If the shape identifier refers to the process data, the process proceeds to step S38, and if not, otherwise.
The process jumps from step S38 to step S39.

In step S38, the corresponding process data is input from the process data input device 2 according to the process data identifier of x, and in step S39.
In (1), the bitmap image is developed on the video memory 4 according to the x coordinate, the shape identifier, and the attached information. Then, after that, the process returns to step S35 to repeat the above process, and finally the screen image is developed on the video memory 4.

As described above, the processing speed can be improved by using this processing method.

[0047]

As described above, according to the present invention, the screens for expressing the design information are classified according to the type of information, and the figures and characters representing the design information are used as the graphic data and classified according to the classification to which each belongs.
