Description

Description: TECHNICAL FIELD The present invention relates to a process display method for a plant that monitors the operation of a thermal power plant, a nuclear power plant, and the like, and an apparatus thereof.

[Conventional technology]

For the conventional remote monitoring device, "Development of the nuclear power plant central monitoring and control system" NUCAMM-80 "" (Hitachi review, September 1980, Vol.62, No.19.P-31 to P-34) ).

According to this remote monitoring device, the display of the monitoring device is performed by the CRT. A plurality of CRTs are used and spatially arranged for easy operation. The display technologies are grouped, screens are updated, and abnormal points are displayed.

[Problems to be Solved by the Invention]

The two-dimensional display method was used for the display on the CRT in the above conventional example. Furthermore, the display method of the monitoring equipment is the symbol method.
The symbol display method is a method of symbolizing a device and displaying this symbol instead of the device.

Therefore, when operating and maintaining the actual equipment, it was necessary for the operator to associate the two-dimensional symbol display with the shape of the actual equipment in mind.

FIG. 4 shows a conventional display example on a CRT. This display example is an example of an overall schematic view of a nuclear power plant. The display targets are reactor R, main steam isolation valve MV, main steam control valve MCV, bypass valve MBV, turbine T, generator G, condenser C, feed pump FP, feed valve FV, and each of these devices. It was a system to connect. Each of the above devices uses the symbol display method.

On the other hand, the process information is also displayed. In Figure 4,
The water level RL of the reactor R and the main steam flow rate MF are display of process information. The reference scales RL ₀ and MF ₀ are displayed together with the water level RL and the main steam flow rate MF so that the actual values of RL and MF can be visually judged. This display format is a bar chart display method.

In the display method of FIG. 4, the device uses the symbol display method, and the process information is also displayed on the symbol device. Therefore, the displayed symbolic device is not an actual device, and the operator must make an ideological agreement between the two, and there are large and small valves among the valves. However, there is a problem in that they have to use the same size symbol display method. Therefore, there is a need for a display method that allows the shape, size, arrangement, etc. of the device to be understood.

The object of the present invention is to provide equipment for 3 according to the operating conditions of the plant.
It is intended to provide a process display device for a plant that has a three-dimensional display.

[Means for Solving the Problems]

The above-mentioned purpose is to capture process data of various equipments that compose a plant and display each process data on the screen corresponding to the equipment. In the plant process display, the equipment process that displays the equipment shape as a three-dimensional solid figure among the equipments. When data is displayed in three-dimensional form, a three-dimensional solid figure representing the shape of the equipment is displayed on the screen based on the graphic information of the equipment, and the shape of the three-dimensional solid figure is the three-dimensional solid shape of the process data. This can be achieved by displaying the shapes of 3 and 4 on top of each other and displaying a system diagram on the screen in which the device in which the process data is displayed in three dimensions and the device in which the process data is displayed in three dimensions such as a bar graph are mixed.

[Action]

According to the present invention, the number of devices depending on the operating conditions of the plant
Dimensional display can be achieved. Furthermore, process data can also be displayed in the three-dimensional display image.

〔Example〕

FIG. 1 shows an embodiment of a three-dimensional display device of the present invention. Three
The three-dimensional display device includes a three-dimensional display (for example, CRT) 1, a three-dimensional information processing unit 2, a screen selector 3, input devices (RMU) 4A to 4N, and a plant 5.

The plant 5 is a nuclear power plant with thermal power, has various devices, and the input devices 4A to 4N capture various process information.

The three-dimensional information processing unit 2 includes a signal processing unit 2A and a screen correspondence selection unit 2
E, coordinate conversion unit 2F, screen synthesis unit 2G, display processing unit 2H, screen selection input unit 2B, three-dimensional database 2C, screen selection unit 2D.

FIG. 2 shows data formation when sending from the input devices 4A to 4N to the three-dimensional information processing unit 2. The header section indicates the beginning and end of the frame, the control section issues various command instructions, and the process data is process information from the plant, such as valve opening, switch ON / OFF, water level, and pressure equipment. It is data for each. CRC is an error check code. In addition to the above codes, this embodiment has a detection position part and a three-dimensional information part. The detection position part and the three-dimensional information part are characteristic parts in this embodiment.

The detection position section displays the detection target device position (or the detection target device number), and the three-dimensional information section gives an instruction of three-dimensional display or two-dimensional display.

FIG. 3 is a display example according to the present embodiment. The reactor R, main steam isolation valve MV, main steam control valve MCV, bypass valve MBV, high pressure turbine HP-T, low pressure turbine LP-T, generator G, recovery Water C, water pump
This is an example in which the FP, the water supply valve FV, and the system connecting the respective devices are three-dimensionally displayed. As can be seen from comparison with the conventional example shown in FIG. 4, one feature is that three-dimensional display is performed without symbol display. Further, as can be seen from the display example of the nuclear reactor R, one feature is that the water level RL is displayed in a stereoscopic display instead of a scale display. Further, the operation / maintenance staff H is displayed so that the size of each device can be relatively understood from the relationship with the size of the operation / maintenance staff H. Further, in the display example of FIG. 3, in addition to understanding the size of each device, the arrangement of each device is also displayed according to the arrangement of the actual device so that the plant arrangement status can be understood from the displayed values.

How the above-described display example of FIG. 3 is realized will be described with reference to the embodiment of FIG. As a premise, it is assumed that the graphic information of each device in FIG. 3 is stored in the three-dimensional database 2C.

First, the process information in the plant 5 is taken in by the input units 4A to 4N. The process information in Fig. 3 is the reactor water level RL and the main steam flow rate MF. In addition to this, the main steam isolation valve MV,
The opening information of the main steam control valve MCV, bypass valve MBV, water supply valve FV and operation information of the water supply pump FP can be imported and displayed as process information. In FIG. 3, these examples are omitted.

The reactor water level RL and the main steam flow rate MF, which are the process information of the plant 5, are converted into the data format shown in FIG. 2 at the input units 4A to 4N. That is, if the input of the reactor water level RL is performed by the input unit 4A, the input unit 4A inserts the detected water level "RL" as "process data" in the format of FIG. Similarly, the position indicating that it is the water level in the reactor is displayed on the “detection position part”, and an instruction indicating that the water level is three-dimensional is displayed on the “three-dimensional information part”. Other control units and CRC follow general data transmission.

On the other hand, if the main steam flow rate MF is input and taken in by the input section 4B, the input section 4B inserts the detected flow rate "MF" as "process data" in the format of FIG. Displays the position of which detection position on the pipe,
It is instructed that it is a two-dimensional display as the “three-dimensional information section”.

The data of the data format thus obtained is sent to the signal processing unit 2A via the line. The signal processing unit 2A is CR
C check is performed, and if normal, the detection position part, the three-dimensional information part, and the process data are acquired.

The screen selector 3 selects the type of screen to be displayed according to the operating status of the plant. Turn on the switch to the effect that it is the display of the entire plant shown in Fig. 3. If it is a partial display, turn on the switch indicating that part.

The screen selection input unit 2B takes in selection information in accordance with the instruction of this switch and converts it into a standard processing format.

The screen selection unit 2D selects the three-dimensional shape symbol of the display device from the three-dimensional database 2C. This result is sent to the screen correspondence selection unit 2E. The screen correspondence selection unit 2E takes in the process information in the plant from the processing unit 2A, and if the reactor water level changes, incorporates the water level process data RL into the reactor water level shape format. For the main steam flow rate MF, the process data MF of the main steam flow rate is incorporated in the shape format of the main steam flow rate. Furthermore, a detection position part and a three-dimensional information part are added.

Next, the coordinate conversion unit 2F performs coordinate conversion so that each display position in FIG. For example, in the case of the reactor water level RL, the detection position part is the existing position of the reactor, and this is converted into the display position on the screen. Here, the existence position of the reactor is the coordinate axis of the reactor building on the three-dimensional database, and is registered on a database different from the coordinate axis of the building of the high pressure turbine HP-T, low pressure turbine LP-T, etc. There is. The coordinates were exchanged so that these coordinates could be unified.

It should be noted that, if the display is made to correspond to the arrangement of the actual machine, it may be possible to stick out the screen, especially in the lateral direction. In this case, the size in the lateral direction may be shortened. In addition, the length of piping between the devices may be shortened. The same applies to the vertical direction. Such conscious processing is performed by the coordinate conversion unit 2F.

Thus, the coordinate conversion unit 2F converts the screen format of the three-dimensional database and the process data display format in the plant into unified coordinates on the screen to be displayed.

The screen synthesizing unit 2G synthesizes and edits the various screens obtained above to synthesize them as one screen data.

The screen that does not require process data or coordinate conversion is 3
The screen selected by the screen selection unit 2D from the dimensional database 2C is combined and edited by the screen combining unit 2G. An example of a screen that does not require coordinate conversion other than process data is a reference graphic for comparison of the size of each device. In FIG. 3, the operation / maintenance personnel H is shown as a figure as a reference figure for comparison.

The display processing unit 2H converts the combined graphic into a display format, and the display 1 displays this. The display result is shown in FIG.

FIG. 5 is an example in which a reference level detector for detecting the water level of the reactor R is displayed. FIG. 6 is a display example by the conventional two-dimensional display method. Four pipes are arranged outside from the reactor R, and the reference levelers L1A to L1D are installed at the tips thereof. According to the display example of FIG. 6 which is a conventional example of such a reactor and a reference plane,
The four reference levelers L1A to L1D were displayed at the same position,
According to the present embodiment shown in FIG. 5, the four reference surface units L1A to L1D provide a three-dimensional display according to each actual machine. Thus, the position, size, and shape of the reference plane can be immediately known from the display screen, which is convenient for operation and operation.

In the above-described present embodiment, the screen is selected by manually instructing the switch of the screen selector 3, but it may be automatically selected according to the state of the plant. In addition to CRTs, examples of displays include liquid crystal and plasma displays.

Further, although the process information is information from the plant, it may be held in the database 2C. In addition, the database of CAD for plant design is database 2
It can also be used as C. Further, the CAD database and the database 2C shown in FIG. 1 may be used together.

〔The invention's effect〕

According to the present invention, it has become possible to three-dimensionally display the state of equipment and processes in a plant. This can improve the operation. Furthermore, since the process information is also displayed, it is possible to obtain a display screen that correctly corresponds to the actual machine in terms of position and shape.
