DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plant operation monitoring device for monitoring plant operation using a display device having a touch screen.

[0002]

2. Description of the Related Art A touch screen is a device for detecting the coordinates of a pressed point when a transparent plate mounted on a CRT screen is pressed with a finger or the like, and is used in combination with a CRT, and is already on the market. Is spinning. There are various methods for detecting the coordinates of the pressed point. For example, as shown in FIG. 12, a strip-shaped transparent electrode is combined in each of the vertical and horizontal directions, an air gap is provided between the electrodes to prevent short-circuit, and only the x and y coordinates of the pressed point are conducted. is there.

[0003] In addition to the method of performing a predetermined input by pressing the transparent plate with a finger, a method of inputting by specifying an intangible surface has also been developed. For more information on this technology, see the article "Touch Screens: Big Deal or Deal" in the US Literature Datamation. Considering such known technologies, the term touch screen conventionally used is not necessarily limited to touching and pressing, but widely used.
This means “means for outputting the coordinates of the designated portion (or information displayed by the coordinates) by giving an instruction to the designated surface”.

When this is mounted on a screen of a CRT, the screen is divided as shown in FIG. 13. For example, when D3 is pressed, the electrodes D and the electrodes are brought into a conductive state as shown in FIGS. In addition, a method of arranging a light emitting diode and a light receiving element in the x and y directions to detect the interruption of the light beam at the pressed point, a method of detecting a change in the capacitance at the pressed point, and the like. is there.

Next, a conventional plant simulator will be described with reference to FIG. The data necessary for the calculation is set on the card reader 31, and the data is input to the central processing unit (hereinafter abbreviated as CPU) 34 by the operation from the console input / output device 33, and the necessary data files and processing programs are stored on the disk 35. Is stored.
The input data and the processing result are printed by the line printer 32. The above is the equipment required before the operation program is created. The created operation program simulates the dynamic characteristics of the plant, and additional equipment required as a plant simulator is added. That is, the setting device 3 attached to the simulation control panel 37 actually operated by the operator
An analog input device 361 for reading the set value of 71 and a digital input device 3 for reading the state of the operation switch 372
62, an indicator 373, a recorder 374, and a digital output device 36 driven via an analog output device 363 based on the calculation result of the calculation program in the CPU 34.
4 is provided with an annunciator 375 and a lamp 376 which are output via the control unit 4.

Conventionally, in a plant simulator, there are several methods for inputting a plant operation to a computer depending on the purpose. In other words, the plant simulator for operator training, as described in the magazine Thermal Power Nuclear Power Plant Vol. 35 No. 5 (1984) p. An equivalent operation panel is created, and input / output processing is performed by this. Taking a nuclear power plant as an example, a plant simulator that can carry out operation training in Japan is a BWR BWR operation training center, PWR
At WR, there were only two nuclear power generation training centers.
While it is desired that such a device be configured at a low cost, it is necessary to simulate plant behavior in real time in response to operator operations online. For this reason, these devices use, for example, five CRTs, as well as a compact and simplified operation panel. Even in this method, a considerable number (600 or more) of plant parameters can be displayed, and an indicator / recorder can be used. Although it can be sufficient for proxy, there is a limit to the number of operation switches that can be simulated, and there remains a problem in standardizing hardware independently of a plant.

The above problem is not limited to a plant simulator but can be applied to a wide range of plant operations in general. In recent years, a method of combining a touch screen device and a CRT has attracted attention as an input method. For example, “Touch Screens” in Magazine Datanation 198 introduces touch screens. However, the technology disclosed in these publications uses a touch screen as an input device of a general-purpose computer, and does not mention any of the purpose, configuration, operation, and effect of a problem specific to plant equipment operation.

FIG. 1 is a schematic system diagram of an input device according to an embodiment of the present invention.

In this embodiment, the simulated operation panel 37 and the process input / output device 36 in the conventional example are replaced with two CRTs and a touch screen. That is, the plant state quantities calculated by the CPU 34 pass through the CRT display control devices 12 and 22 and are output to the CRTs 1 and 2 (11 and 12).
Displayed in 1). The operation from the operator is performed by the touch screen control devices 12 and 2 by the touch screens 13 and 23.
4 to the CPU 34. The details are described below.

As for the simulation result of the plant state, in the conventional method, the analog state quantity is presented by the indicator 373 and the recorder 374. In this embodiment, the instantaneous values are displayed by numerical display or bar chart display shown in FIGS.
The elapsed value is presented by the trend display shown in FIG. If recording is required, it can be created by hard copies 15 and 25. The alarm screen shown in FIG. 6 may be used as a substitute for the annunciator 375.

A description of each screen and details of a method of operating the simulator will be described below. The present embodiment is a simulator for a nuclear power plant, and FIG.
It is an RT screen. The operator knows the detailed operation state, or touches a box of the system shown in the lower part of FIG. For example, if you want to know the detailed operation status of the engineering safety system and carry out the operation operation in order to conduct simulation training when an accident occurs in the reactor, if you touch the box section of the “safety system” The screen shown is displayed on the CRT instead of the screen shown in FIG.

This screen is for monitoring the operation state of the engineering safety system, and the CRTC is activated from the screen.
It can be seen that a flow rate of 0 T / H flows into the reactor pressure vessel. On the other hand, it is not injected into the reactor pressure vessel from HPCS and LPCS. In order to operate the HPCS, the operator touches “HPCS” below “operation system” at the right end of the screen, and a screen shown in FIG. 4 is displayed. This system is composed of three valves and one pump. All valves are in a fully closed state, the pump is in a stopped state, and the display colors are all green. The operator takes the water source from the condensate tank,
921 is touched, and after confirming that the part concerned has green flicker, the lower part "open" is touched. As a result, the X and Y coordinates are input via the touch screen input control device 14, the opening command for the valve (1) is simulated by the CPU 34, and when the valve 1 is fully opened, the valve on the screen via the display control program CRT display control device 12 ( 1)
The display color changes to red. Next, to start the HPCS pump 924, touching the relevant portion on the screen causes a green flicker, and touching "start" at the bottom of the screen simulates the start of the HPCS pump 922 by the CPU 34 in the same procedure as described above. As a result, the display color becomes red. As a result, the pump discharge pressure also increased, and it was confirmed that "pressure 0 kg" on the screen was changed to "pressure 76 kg". Valves (3) and 933 were opened in the same procedure as above, and the water of the condensate pump was Is calculated by injecting into the pressure vessel. As a result, "Flow rate OT / H" on the same screen changes to "Flow rate 1,800 T / H".
Since the normal operation of the PCS is confirmed, the operation procedure ends. In the meantime, when referring to the reactor water level and pressure, which are the main parameters related to the safety of the reactor, by touching the “trend screen” at the bottom of the screen, the screen shown in FIG. 5 is displayed. From the figure, it is shown that the water level temporarily drops but tends to recover when the HPCS is started. In addition, an alarm screen shown in FIG. 6 is used as an alarm screen generated during normal operation. Further, a screen shown in FIG. 7 is prepared for operation of a device not shown in the system diagram. For example, the interlocking state of the starting air extractor is shown on the right side, and the interlocking operation is currently being performed. If you want to stop the interlocking, first touch the left end No. 2 to display the selectable state of the switch on the lower operation switch display section, that is, “interlocking stop”, “independent”, “interlocking start”, and “interlocking stop”. Touching the "" part simulates the interlock stop of the device. Further, a screen shown in FIG. 8 is prepared for setting the controller. Currently RCIC
The actual flow rate is 140 while the set value is 145 T / H.
T / H is flowing. When increasing this, first, No. 1
Touch to enable the RCIC touch,
When "increase" is pressed, the set value increases for that period, and when the hand is released, the set value stops in that state. If you want to decrease it, you can do so by pressing "Reduce". After that, the controller controls the actual flow rate to a set value. The above is the case of the automatic mode, but when the "manual" part is touched, the mode is switched to the manual mode, and the flow control valve is directly operated by the increase / decrease operation to operate the opening.

FIG. 9 shows a software configuration of this embodiment. Input signals from the touch screen control devices 14 and 24 are input to the input processing units 341 and 342 at the XY coordinates and
Analyze the meaning from the CRT screen type. In the case of a display screen change, the display is changed to the screen, and in the case of an operation request, the finger processing request, for example, a valve opening operation, a pump activation, an increase / decrease of a set value, and the like are set in the operation database 343. The plant simulation unit 344 calculates a plant state that is desired to be the content of the operation database 343, and generates a plant database 345.
Then, for example, the reactor water level, the reactor pressure, etc. are written. Based on these data, the display processing unit 346 attaches data corresponding to the screen requested to be displayed and outputs the data to the CRT display control devices 12 and 22.

FIG. 10 shows another embodiment of the present invention. In the present embodiment, the operation status of the nuclear power plant 8 is monitored, and when an abnormality or accident occurs, the engineering safety facility 9 is activated according to the judgment of the operator. In the figure, the description has been considerably simplified for convenience.

The states of the reactor system 81 and the turbine system 82 are input to the central processing unit 6 by a process input / output device 74, and the operation states of the units are indicated by CRT display control devices 1, 2 (33,
34) and are displayed on CRTs 1 and 2 (31, 32). FIG. 4 shows a display example. When an abnormality or accident occurs in the reactor, simply stopping (scram) the reactor may not be enough, and the operator may use the high pressure reactor core spray system (HPCS) 92 and the cooling system when the reactor is isolated as necessary. (RCI
C) 94, an automatic pressure reduction system (ADS) 96, and a low pressure core spray system (LPCS) 98
Use as appropriate via 3,95,97. In this embodiment, the activation for that is performed on the touch screen 1. The touch screen shown in FIG. 1 is used, and the resolution is 6 in the X-axis direction and 5 in the Y-axis direction. The lower part of the whole plant screen of FIG. 2 is used for screen selection, and when the “safety display screen” is pressed on the touch screen 1, the screen shown in FIG. 3 is displayed on the CRT 1 (31). Subsequent operation procedures are the same as those described in the above embodiment, except that the operation results are reflected in the arithmetic processing of the simulator, but the equipment of the actual plant is operated.

FIG. 11 shows a software processing configuration of the present embodiment. An input signal from the touch screen input control device 1 is periodically input to the input processing units (1) and 61,
When a touch is detected, the XY coordinates are output. The operation processing unit 63 issues a screen change request to the display processing unit (1) if the display screen is to be changed, and outputs the output processing unit 64 if it is a device operation, based on the X / Y coordinates and the type of screen being displayed.
And outputs a valve opening / closing command and a pump start / stop command to the process output device 74.

In each of the above-described embodiments, the CRT and the touch screen represent the plant system and perform the switch function, so that a large number of switches can be displayed with compact components, and the possibility of erroneous operation is reduced. Also, the manufacturing cost is relatively low compared to its multifunctionality. In addition, when it is necessary to change the switch mechanism, the switch mechanism can be quickly and easily changed (that is, the control target can be changed) by modifying the program without changing the wiring.

[0020]

As described in detail above, according to the input device of the present invention, it is provided with a large number of switch functions and display functions for operating the plant, and there is no fear of erroneous operation.
It has an excellent practical effect of low cost.
