Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a plant simulator used for plant operation training, learning and research of plant dynamic characteristics, and the like.

[Technical background of the invention and one point in between] In order to learn the operation line of a plant or the dynamic characteristics of a plant, the dynamic characteristics of an actual plant and the functions of a control device are simulated by a computer, and the results are compared to the actual plant. A plant simulator is known that enables simulated training equivalent to an actual plant by outputting to a simulated control panel approved by the government.

However, this equipment requires a large control panel equivalent to the size of an actual plant, and an instructor co-op for the instructor to supervise the progress of the operation training. The configuration is large and requires a lot of space and equipment cost, making it difficult to conduct driver training.Therefore, in order to make the driver training more compact and convenient, a CRT display device was used as an input/output interface. The plant simulator used was developed. According to this plant simulation device, screens that combine plant system diagrams with instruments, bar graphs, trend graphs, or operating equipment such as valves and pumps that represent the process quantities of each part of the plant can be switched one after another on the CRT display. will be displayed. Furthermore, by providing a touch screen on the surface of the screen, operating devices can be operated by touching the screen from above, which eliminates the need for a control panel, and replaces the large control panel with a CRT display. Because of this change, the equipment space has become extremely small, the cost has also been greatly reduced, and it has become easier to use.

However, in this plant simulator, when operating the operating devices on the CRT display screen via the touch screen, there is a problem in that displaying the operating end for each operating device greatly reduces the display efficiency of the screen. Ta. That is,
The operating end of each operating device is open, close, automatic/manual switching, and holding 2.
It consists of a combination of various push buttons such as start and stop, but if these various operation terminals are displayed near each operation device display, the display of these operation terminals will occupy most of the screen, and the important There was a problem that the display of the plant system diagram was restricted. On the other hand, it may be possible to display only one set of these various operating terminals for each operating device and select them according to the operating device to be operated, but in this case, it is possible to know in advance what kind of operating terminal each operating device has. The problem is that the single selection operation becomes very complicated, and operation is much more difficult than in a plant simulator equipped with a simulating operation panel.

[Object of the Invention] An object of the present invention is to solve these problems and provide a plant simulator that can easily utilize efficient learning at low cost.

[Summary of the Invention] Therefore, the present invention provides that by selecting an operating device such as a pump or valve on a system screen displayed on a display device, an operating end that matches the operating device is automatically displayed on the screen. By displaying the plant on a screen and making it possible to operate it from the operating end, the display efficiency of the screen is increased and operability comparable to that of a plant simulator with a simulated operation panel is ensured.

[Embodiments of the Invention] Hereinafter, an embodiment of the present invention will be described as shown in FIG.
, an actuator calculation processing section 12h' that calculates the state of the operating equipment such as the valve opening degree and pump status given to this model processing section, and a valve necessary for calculating the state of the operating equipment to this actuator processing section. The actuator parameter unit 13 provides parameters such as opening/closing time and type of the actuator, and performs simulated calculation control.

Next↓This 1 The display control device 2 is the calculation result S1 of the model calculation processing section 11 and the calculation result S of the actuator calculation processing section 12.
The simulated plant state in step 2 is displayed on the CRT 3 in the form of a system diagram or trend graph.

On the other hand, a touch screen 4 is disposed on the front of the CRT 3, and the learner performs driving operations by touching the operating end on the system screen through the touch screen 4.

The signal processing device 5 receives the signal 01 from the touch screen 4.
and the display screen number signal 02 from the display control device 2, and if it is an operation device selection operation, the operation device number 03 is received.
．． In the case of operating the operating end, an operating signal 04 is output.
” The operation end selection bag [6 inputs the operation device number 03, determines the type of operation, and outputs the front thread operation end signal S3 to the display control device i!2.

Further, the operation end operation signal processing device 7 inputs the operation signal 04 and outputs the operation device drive signal 05 to the actuator calculation processing section 12.

FIG. 2 shows the operation 1) of the □ signal processing device 5, operating end selection device 6, and operating end operation signal processing device 7 shown in FIG. and the processing until the control end is displayed,
It shows the processing until one operation signal from the operation end is input to the actuator calculation processing section.

Moreover, FIG. 3 is an example of a display screen, and shows the operating end area and the shape of the operating end.

In the above diagram, a position signal 01 from the touch screen 4 is input to the signal processing device 5 as a position signal on the touch screen 4 (101). At the same time, the currently displayed screen number is sent from the display control device 2 by the display screen number signal 0.
2 (102).

On the other hand, the signal processing device 5 stores the coordinates of the lower left and upper right points of the operating end area (rectangle) for each screen.
I, and determines whether the position of the position signal 01 exists inside the operating end area 9 defined by the above two points (
103). This determines whether the operation on the touch screen 4 is a selection of an operating device or an operation of an operating end.

First, in the case of selecting an operating device, when the signal processing unit [5 finds that the above position signal O1 indicates the selection of an operating device, it refers to the table T2 that stores the operating device number with coordinates for each screen, and A device number is calculated (104). This operating device number is input to the operating terminal selection device 6 as an operating device number signal 03 and is simultaneously stored in the memory old.

The operating end selection device 6 stores a table T3 that defines the operating end type for each operating device number, and determines the operating end type by referring to this table.
Display control device on display operation end signal S3! ! 28 output and simultaneously store it in the memory M2 (105). The display control device 2 controls the operation end area 9 of the CRT screen 8 currently being displayed.
The operating end 10 specified by the signal S3 is displayed in the lower left corner. When an operating device is selected from the touch screen 4 in the above process, the operating end 10 that matches the operating device
will be displayed.

Next, when the operating end 10 displayed in the above process is operated, when the signal processing device 5 determines that the position signal 01 from the touch screen 4 is the operating end operation signal, each Referring to the table T1 that stores the coordinates of two points in the operating end area 9 for each screen, converting the coordinates into coordinates where the lower left corner of the operating end area 9 is (0,0) (106);
This is because, as mentioned above, the operating end 10 is displayed in the operating end area 9 at the lower left corner, so from the x and ■ coordinates of the position signal O1 from the touch screen 4,
■Easily determined by subtracting the coordinates. As a result, the process of determining what kind of operation has been performed, which will be described later, can be performed without being aware of where on the screen the operating end is displayed. The position converted to the coordinates on the operating end area, signal O1, is input to the operating end operating signal processing device 7 as operating signal 04.

Operation signal processing device i! 7, referring to the table T4 that stores the coordinates of each operation end 10 where each operation button display for each operation end type, e.g., "r open" and "close" for a valve, is located, and determines what kind of operation is to be performed. An actual operating device drive signal O5 indicating whether the operation has been performed is outputted to the actuator calculation processing section 12 (107). At this time, to refer to the table, display the operating terminal type %S
3 is input from memory M2. Further, in order to inform the actuator arithmetic processing unit 12 which operating device has been operated, an operating device number signal 03 is also input at the same time.

Thereafter, the actuator calculation processing section 12 calculates the actuator status S2, such as the valve opening degree, by referring to information such as the valve opening/closing time in the actuator parameter section 13, using the operating device drive signal OS. This actuator status S2 is input to the display control device 2 and CR
Displayed on the T3 system screen. It is also input to the model calculation processing section 11 and used for calculation of process quantities.

Finally, the process value S calculated by the modem calculation processing section 11
1 is input to the display control device 2 and displayed on the system screen on the CRTa.

In this way, the desired operation of the operating end of the operating device can be reliably performed with a small display space.

In the above embodiment, a touch screen is used as the operating device, but it goes without saying that a keyboard, light pen, mouse, trackball, etc. can also be used.

C*Bright effect] As explained above, according to the present invention, when an operating device is selected, the operating end is displayed on one screen each time, so the display efficiency of one screen is extremely high. In addition to getting better,
Operation becomes more reliable, and the operation of the simulated plant becomes more efficient.
