Description

TECHNICAL FIELD The present invention relates to a small simulator used for learning analysis of a large-scale plant, and particularly to a small simulator suitable for improving learning / analysis efficiency and the same. The present invention relates to a display method and a storage device and a display control device that are mounted on this small simulator.

[Conventional technology]

As a small simulator for simulating the operation of a large-scale plant such as a power plant to allow beginners to learn and analyze the operation, or to conduct a training to generate a simulated accident and converge it, Japanese Patent Publication No. There is a conventional technique described in Japanese Patent Publication. In this conventional small simulator, in order to make the device itself small and inexpensive, the simulator operation switch, the plant component equipment, etc. are made into software so that the computer and the display device such as CRT can simulate the switch as much as possible.

[Problems to be solved by the invention]

In a large-scale plant such as a power generation plant, the number of its constituent devices is enormous, and it is almost impossible to remotely control all the devices from the central control room because of the wiring and the operation panel. Therefore, only the important components and frequently used components can be remotely controlled from the central control room, and the less frequently used components can be operated by going out to the site.

Learn the operation of such a large-scale plant and accident countermeasures
When using the small simulator described in Japanese Examined Patent Publication No. 62-29793 for analysis, the plant components displayed on the simulator's display screen cannot be operated remotely in the central control room in the actual plant and can be operated on site. It may be a device that must be operated, and if you mistakenly recognize that it can be operated in the main control room and learn it, it will take time and effort to settle this accident when the accident actually occurs. There is a risk that a delay may occur, leading to a fatal accident.

It is a first object of the present invention to provide a display method of a small simulator for large-scale plant learning analysis, which can distinguish whether it can be remotely operated or needs to be operated on site.

It is a second object of the present invention to provide a small-scale simulator for large-scale plant learning analysis, which can distinguish whether it can be remotely operated or needs to be operated on site.

A third object of the present invention is to provide a storage device suitable for mounting on a small-scale simulator for large-scale plant learning analysis that achieves the second object.

A fourth object of the present invention is to provide a display control device suitable for being installed in a small simulator for large-scale plant learning analysis that achieves the second object.

[Means for solving the problem]

The first object is achieved by displaying, when the system diagram of the large-scale plant is displayed on the display screen, the data indicating that the device cannot be operated unless the device goes to the site.

Further, the above-mentioned first object is achieved by, when a certain component device is designated in the displayed system diagram, displaying the operation place of the device and the like.

The second object is achieved by including a storage device that achieves the third object and a display control device that achieves the fourth object.

The third purpose is to store data indicating whether or not the equipment can be operated without going to the site, or data indicating the operation place or installation location of the equipment, corresponding to the plant constituent equipment. Will be achieved.

The fourth object is achieved by reading the data from the storage device and displaying the data on the display screen for the third object.

(Operation)

In the simulator according to the present invention, since the displayed plant constituent equipment is also equipment that cannot be operated without going to the site and the operating location of the site, etc., the learner learns the equipment from the central control room. Erroneous recognition that remote control is possible can be eliminated, and learning efficiency can be improved.

〔Example〕

Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is an overall configuration diagram of a small simulator for power plant learning analysis according to an embodiment of the present invention. This small simulator is a simulated computing device 1 that performs various simulated computations.
A display control device (CRT control device in the embodiment) 2, a data storage device 6 for storing various data, and an operation panel 3
Consists of The operation panel 3 is a CR, which is an example of a display device.
It is composed of T4 and an operating device 5 including a keyboard and various switches. The simulated computing device 1 reads the data about the logical model of the physical model stored in the data storage device 6 based on the instruction input by the operator from the operation panel 3, performs the operation analysis in each model, and displays the analysis result. It is sent to the display control device 2. The display control device 2 converts the signal from the simulation calculation device 1 into a drive signal for the display device 4 and sends it to the display device 4, and displays the simulation calculation result on the screen. The display device 4 is provided with an input means such as a touch screen or a light pen, and an input signal from the input means is taken into the simulated arithmetic device 1 via the display control device 2. Since the operation analysis calculation of the above-described physical model performed by the simulator is not related to the present invention, its explanation is omitted.

The data storage device 6 stores data relating to the system diagram of the power plant for each screen unit, and further, for each component device of the power plant, if the device can be controlled from the central control room, that (The symbol "MO" in this embodiment) and its device number are stored, and in the case of a device that cannot be operated without going to the site, the data ("LO" in this embodiment) Symbol) and its device number are stored. Furthermore, for equipment with the above-mentioned "LO" symbol indicating that remote operation is not possible, the operation location (eg "site" or "RB" indicating the actual operation location)
1F ”(showing the first floor of the reactor building) and the actual installation location of the equipment (for equipment whose operating location is“ RB1F ”)
For example, "RB-2F-02-08". If the operating locations of a plurality of devices that are to be visited and operated on site are collectively arranged, the operating location and the installation location will be different. ) Is stored.

FIG. 2 is a diagram showing a system diagram of a part of the power plant displayed on the CRT 4. In this example, pump 14 transfers fluid from tank 10 to device 11 and device 12. Where valve 13 and valve 15 and pump 14
Is a device that can be remotely operated from the central control room in the actual plant, and the valve 16 is a device that must be operated by going to the site.

In the embodiment shown in FIG. 2, in order to clearly distinguish between the two, the display control device 2 displays the MO code in front of the device number for devices that can be remotely controlled in the central control room. For equipment that requires you to go and operate
The LO symbol is displayed before the device number. Therefore, the operator can clearly understand which device should be operated and where in the actual plant only by looking at this screen.

An example of a specific operation will be described with reference to FIG. For example, when the suction valve 13 is first opened when starting the pump 14, the suction valve 13 is selected with a light pen or a touch screen. The operator inputs the selection command in this way, and the simulated arithmetic unit 1 shown in FIG.
When this command is received via, the valve 13, which has been displayed as a thin line until then, is displayed as a thick line, and informs the operator that the selection command signal has been received. At the same time, the switch position corresponding to the position of the actual operation switch of the selected device is displayed in the area indicated by reference numeral 19 in FIG. In this case it is a valve, so in area 19 "open",
"Closed" is displayed. In the case of a pump, "start" and "stop" are displayed.

After this, the operator opens the valve 13 and thus designates the "open" position of the area 19. Simulated computing device 1 of FIG.
Receives this signal via the CRT control device 2, reads it from the storage device 6, and stores it inside the model.
At the same time as simulating the operation of 13 in the opening direction, the operator is informed that the valve 13 is operating in the opening direction by changing the display color.

Through the above operations, the operator feels that the valve 13 operated in the main control room has been operated in the opening direction.

Next, if the pump 14 is started by the same operation, the valves 15 and 16 must be opened before starting the pump, for example, in order to secure the minimum flow rate in order to prevent the shut-off operation of the pump. However, it is assumed that the pump 14 is accidentally started before the valve opening operation. At this time, valve 15
Since it has been known that (1) can be operated from the main control room (due to the letters MO), there is a possibility that the pump 14 can actually be saved by opening the valve 15 immediately. On the other hand, if there is no indication of the operation location, accidentally opening the valve 16 will not cause damage to the pump in the simulator, but in reality, until a person goes to the operation location on the site and operates it. Will be delayed. In other words, the physical phenomenon that actually occurs is different from the training. It can be easily understood that the display of the LO showing the operation in the field is important in preventing such confusion.

Now, in the embodiment of FIG. 2, an example in which the distinction between the main control room and the equipment operated in the field is realized by the letters and symbols of MO and LO has been described, but as another embodiment, as shown in FIG. When the selection of the device is input on the touch screen, etc., the operation location of the device is directly displayed. This operation place is to be displayed here by opening the window 20 completely independently of the device number. By doing so, it becomes easy to provide not only the alternative information of the central control room and the site but also more detailed information such as which floor of which building. It is also effective to simply display “site” on the window 20.

In addition, it is also effective to change the display color depending on the operation location or display a symbol indicating a predetermined operation location near the display location of the device.

Further, FIG. 4 shows an embodiment in which, in addition to the operation location, information on the installation location of the device is also displayed. In this example, it indicates that the operation location of the selected equipment is on the first floor (RB1F) of the reactor building, and the actual equipment installation location is on the X coordinate 02, Y coordinate 08 of the second floor of the reactor building. ing.

In this way, by displaying not only the information on the operation location but also the information on the installation location, the operator can draw the plant image more concretely, and the training effect is enhanced.

Now, a specific display control procedure for specifying and displaying the operation location or installation location of the device as described above will be described below.

In addition, as shown in Fig. 2, the operation location is preceded by MO or
The method of displaying by LO can be realized by previously storing the operation location in one-to-one correspondence with the device for each screen of the CRT 4, and thus the description of the control procedure is omitted.

Depending on the plant, the equipment number may include information such as equipment type and affiliated system. In that case, if the operating location information is also written on all the devices as shown in FIG.
Long strings are required for each device. Therefore, there is a possibility that it takes a long time to read the data. Therefore, in such a case, it is desirable to display the necessary information only for the selected device as shown in FIGS. FIG. 5 is a flowchart showing a display control procedure in that case.

First, when starting the learning, the initial condition of the simulator is set according to the behavior of the plant to be learned (step 10). According to these setting conditions, the simulation computing device 1 of FIG. 1 initializes the simulation model (step 15) and starts the simulation (step 20).

Next, in step 25, the learner (operator) decides which system of the plant is to be used for learning, and a screen for operating the equipment or a screen for displaying the state of the plant (for example, the fourth screen).
Select the screen shown in the figure) by entering the screen number. According to this, the simulated arithmetic unit displays the selected screen in step 30.
Is displayed and the screen that has been selected is stored.

When the learner operates the device and specifies the target device on the CRT, the command is fetched (step 35), and which of the devices displayed on the CRT is specified is determined from the X, Y address on the screen. (Step 40), it is determined which equipment of the plant the equipment corresponds to from the screen No. and the X and Y addresses (step 45). In the processing so far,
For the equipment selected and specified by the learner, the model equipment number, installation location, and operation location in the actual plant are stored in advance, and the information of the selected CRT screen No. and X, Y address is used. Uniquely for each device (step
50) It will be. Therefore, all the data to be displayed in FIG. 3 or 4 has been obtained.

Next, based on this data, the operation location or the like for the device is displayed in step 55, and when an operation instruction signal is input, it is taken in and the model is moved to perform a simulation (steps 60, 65). The result is steps 70 and 75.
Display as changes in equipment status and process amount.

Needless to say, by connecting the simulator according to the present embodiment to the diagnostic device of the actual plant, it is possible to verify what causes the diagnostic result of the diagnostic device was obtained.

〔The invention's effect〕

As described above, according to the present invention, it is possible to clearly distinguish where the device to be operated originally can be operated, and thus it is possible to determine whether or not the operation is appropriate as a countermeasure for an accident convergence. There is an effect such as that, and the learning efficiency of the simulator can be improved.
