Description

[Detailed Description of the Invention] [Technical Field of the Invention] Plan Displayed in the Present Invention) (Plant control that allows plant operation and control to be performed through the display device based on Pt information) Regarding equipment.

[Technical background of the invention and its problems]

In large-scale plants such as Power Generation H, the operation and control of the Sibrants is generally controlled by centralized remote control from a central control room. There is a trend towards larger scale.

For this reason, central centralized monitoring functions are becoming larger and more sophisticated in order to further improve plant safety and reliability. This allows ground operation, monitoring,
The current situation is that the equipment has become unnecessarily large, as a large number of monitors, lamps, alarms, and operation switches are arranged as monitors and control panels used for operation.

Therefore, in recent years, various monitoring information for plant turning points has been displayed on color CRT displays, which has consolidated monitoring information and reduced the need for conventional meters, running lights, alarms, etc. However, in such monitoring and control panels, monitoring is performed using a CRT display, and operations are performed using operation switches and controllers placed separately. However, the correspondence between surveillance alarms and control devices is not intuitive, and there are many cases of erroneous operation.

Therefore, as a countermeasure to this problem, you can use a color CRT display and a light pen, joysticker, key bead, etc. to directly indicate the shapes of pumps, valves, etc. on the system diagram that is displayed on the color CRT display and shows the nine-point piping. Color C
Techniques are being introduced that allow continuous rotation of the ground without error by directly specifying the mf5 component device from the RT display.

PA↓1 diagram shows an example of the configuration of a plant control device such as ξ. As shown in Figure 1, there is an arithmetic and control unit 1, a main memory 2 and an auxiliary memory 3 connected to it, and a high-speed transmission line for inputting and outputting plant information and displays to and from the arithmetic and control unit. A bus 4 and a low-speed bus 7 constitute an electronic slave computer. A process person, an output device 8, and a peripheral device 9 are connected to the low-speed bus 7 of the electronic computer, and the process person, output device 8, and peripheral devices 8 and 10 transmit input and output to the plant 10. . Also, computer express bus 4
color CRT via high-speed bus interface 5.
An Il control device 6 is connected. This color CRT
The control device 6 includes a display control processor 61, a display control unit 62, a color CRT display 63, and a color CRT.
It is composed of a dual pen control unit 64, a light pen 65, a keyboard control unit 66, a key gate 671, and an adapter 68 as input devices to the display 63.

In this color CRT control device 6, the color CRT
A display control bus that outputs a display to the display 63.

Toro 2 is connected to display control devices 69 via display control bus 69. In addition, the operation data from the write-in 65 and the keyboard 67 are displayed on the color CRT display 6.
A light pen control unit 64, a key dart control unit 22, and a trolley 6, which are to be displayed on the display controller 3, are connected to the display control processor 6 via a display control bus 69'. The additional pressure adapter 68 is connected to the display control bus 69 so that display data obtained from the high-speed path 4 through the interface 5 can be captured by the adapter 68 .

In the above description, the light pen 65 and key bead 67 were cited as representative examples of the input device, but other devices such as a snail and a tracker ball are also functionally equivalent to the light pen.

In such a configuration, a display such as a color CRT display is used as an auxiliary means for other instruments, so
The displayed information is updated relatively slowly (for example, once every few seconds). Therefore, no particular problem occurred when the display control processor 6 collectively processed the display output processing to the color CRT display 63 and the input processing from the light pen 65, keypad lower, etc.

However, as plant control began to be performed using only displays and human-powered devices, the periodic update rate of display information became faster and faster.
That is, the response time from when the state quantity of the plant changes until it appears on the display 1) 1j is very important, and such an update cycle must be performed at a very high speed. For example 1
Updates must be performed several times per second or more. Therefore, when a very large number of tables are sent from the display control processor 6 via the display control bus 69 to the display control unit 62 and color CRT display 63, the display control processor 6 and the display The control bus 69 becomes heavily loaded.

Therefore, even if the write-in 65 is operated in such a case, the operation information is transmitted to the adapter 68, the high-speed bus interface 5, and the high-speed path instead of being manually interrupted to the display control processor 6 via the light pen control unit 64. There is a drawback that the input to the arithmetic and control unit 1 via step 4 is ignored. This is due to the fact that input costs are being ignored more and more as the frequency of display updates needs to be increased.
The plant cannot be operated correctly via the display.
It is becoming a serious matter of change. Moreover, since conventional light pens have a structure in which the light pen captures the display light displayed on the CRT display, the light pen and CR
It was difficult to control the T display separately. In addition, keyboards, joysnipers, tracker mails, etc. function to move the cursor (display indicating the position of human power) that appears on the CRT display, and these must also be operated in unison with the display. There was an inevitability that it would not happen.

[Purpose of the invention]

An object of the present invention is to provide a plant control device that can reliably operate and control plant equipment displayed on a display, regardless of the update rate of display output to the display (1'J). shall be.

[Summary of the invention]

It also reads the ground input, processes it, and outputs it to the plant.

The control device includes means for periodically displaying input information from the plant on the display at high speed, and means for inputting an output signal from the touch screen to specify a display screen on the display. and means for specifying a Sibrand device based on an input signal from the touch screen and outputting an operation output to the plant, so that plant operations can be performed from the touch screen based on display data displayed at high speed. This is characterized by the fact that the
