Description

TECHNICAL FIELD OF THE INVENTION The present invention relates to a process display device that can easily create and change CRT display screen data in a computer system used for monitoring and controlling plant processes.

Technical background of the invention and its problems In recent years, CRT display devices have been introduced for process monitoring and control.
Although it has achieved great results, in response to demands for expanded, larger-scale, more complex process control functions, and stronger monitoring,
A huge amount of data is now required to be displayed on a larger number of screens.

In a system that graphically displays process quantities on a CRT display, the data that makes up the screen to be displayed on the CRT display includes fixed screen display data that shows the system diagram, arrangement of plant components, etc., and fixed screen display data that shows changes in process quantities. There is variable screen display data for displaying corresponding variable displays, ie, contact changes, analog changes, numerical changes in process quantities, etc. These data are created in advance to create the screens necessary for monitoring and controlling plant processes.
Conventionally, this creation requires a great deal of effort.

Therefore, various devices and devices have been developed that can create data with less effort, and efforts are being made to improve efficiency. For example, when creating a screen, conventionally data was created offline on a computer system by hand or with various devices, read into the system, and displayed on a CRT display to visually check the displayed data. It is carried out. In this case, confirmation of the display data and further checking of the visibility and comprehensibility of the color scheme, composition, symbols, etc. of the screen can be performed only after the screen is displayed on the CRT display device. In addition, if the data needs to be corrected or added as a result of visual confirmation by loading the data into the computer system and displaying it, the data should be taken out of the system and corrected/added.
Additions must be made. In order to improve this, the computer system has a function to correct and add display data,
From visual confirmation to data corrections and additions, the data is stored in the system! There is a device that makes it possible to do this on the go. This is done by storing the elements (pixel patterns) necessary for configuring the screen in advance in a storage area within the system, and then using an input/output device that is directly connected to the system.
This includes inputting information for displaying, creating, changing, and adding information.

However, pixel patterns often require a large number of types to express a process, and because they are divided into constituent elements, they are often unclear and difficult to understand. The device takes care to make these pixel patterns easy to handle. was needed.

Purpose of the Invention The present invention is an apparatus for creating screen data online, and while displaying screen data on a CRT display device, display information for configuring the screen and a pixel pattern or several pixel patterns that are units of the screen. Macro patterns, etc., expressed as symbols by aggregating them, can be easily entered through interactive operations using an input device, and are used to improve the quality of CRT display screens and create screens in process monitoring and control at power plants, etc. - The purpose is to obtain a process display device that can improve the efficiency of operations and maintenance such as changes and corrections.

SUMMARY OF THE INVENTION This invention is designed to directly connect the CPU of a computer system to an input device.
This machine has a function key that interrupts the machine, and the 1r\ key is placed separately from the normal character key for inputting characters, and when the function key is operated, a pattern of symbols is directly stored in the storage device. By making it possible to display on the 3T display device, it is now possible to easily create, change, and modify screens on the 3T display device through interactive operations using these function keys and character keys. Furthermore, in addition to the pixel patterns prepared in advance by the system as units constituting the screen, it also has the function of creating, changing, and modifying any pixel pattern and checking the display thereof.

FIG. 2 is a diagram showing the input/output relationship of the present invention. Input device 12 has character keys 13 and function keys 14 . That is, the character keys 13 are installed on the input device 12, and are used to construct pixel patterns as constituent elements of screen data on the CR1 display screen of the CRT display device 11 during interactive operations. It is a key that has a function assigned to it.

On the other hand, the function key 14 is located on the input device 12, and the character key 13 is
This key is installed separately from the process computer 1 and is used to directly interrupt the process computer 1 to display a function request during an interactive operation and a macro pattern which is a set of pixel patterns. FIG. 4(a) is a plan view of these character keys 13 and function keys 14 provided on the input device 12. Details will be described later.

Next, the interrupt determination processing means 15 converts signals from each key of the input device 12 into signals from the character keys 13 and function keys 14.
The signal from the character key 13 is sent to the character key code decoding means 16, and the signal from the function key 14 is sent to the interrupt processing means 19 on the process computer 1.

The input/output control device 10 includes this interrupt judgment processing means 15.
, decode the code of the character key 13 and display the CRT display device 1.
1, a character key code decoding means 16 having a function of converting the data into screen data for display on the screen, and an IT display device 11.
It is used to output a refresh image of the screen displayed on the screen at a constant update cycle, to maintain the afterimage of the screen displayed to the human eye at all times, and to ensure that the screen remains displayed. Refresh memory means 17 for storing data, and pixel pattern registration where pixel pattern data is registered in order to display the 11th page data sent from the refresh memory means 17 as a pixel pattern. Means 18 are included.

When it becomes necessary to change the screen creation in process monitoring and control, the user presses the function key 14 of the input device 12 to
The processing means 4 is activated. When activated, the second processing means 4 displays an input request on the CRT display device 11, and while the user performs an interactive operation of inputting the requested information from the input device 12, the second processing means 4 displays data for double-sided display. create.

As shown in FIG. 3(a), the screen of the CRT display device @11 is composed of m x m sections, and these sections are called pixels. Also, each pixel is nXn' as shown in FIG. 3(b).
It consists of points, and these points are called dots.

By matching the positions of these glowing dots, any pattern can be displayed on the screen. The pixel and macro patterns required to construct a CRT screen for process monitoring and control of a particular plant are constant.

Therefore, a macro pattern is a pattern in which a plurality of pixel patterns are lined up at predetermined positions to form a meaningful pattern, such as the shape of pulp or the shape of a pump, as shown in Figure 3(d). , the shape of a transformer, and other commonly used standard patterns are determined as macro patterns. Such pixel patterns and macro patterns are set in advance in the pixel pattern data storage section 9 on the auxiliary storage device 6,
A pixel pattern and a macro pattern are assigned to each key of the keyboard input device 2. Then, by key operation, these pixel patterns and macro patterns are CR,
Display it at a predetermined position on the T screen.

This is done by moving a blinking glow (called an entry marker) for specifying the input position of screen data set on the CR1 screen to a predetermined position using the entry marker movement key 26, and then displaying the pattern you want to display. By pressing a key assigned to , an inset pattern and a macro pattern are constructed at a predetermined position on the CRT i-side. At this time, the display color can be arbitrarily set using the key 25 for specifying the display color. Note that keys 22, 25, and 26 are character keys.

The key 22 is a key for displaying pixel patterns and alphanumeric characters, the key 25 is a key for specifying a display color, and the key 26 is a marker movement key. Signals output from the input device 12 by pressing these keys are decoded by the character key code decoding means 16 via the interrupt judgment processing means 15 in the input/output control device 10, and the screen is displayed on the CRT display device. The data is stored as double-sided data in the refresh memory means 17 for display.

On the other hand, keys 23 and 24 are function keys. The key 23 is a key for starting each module, and the key 24 is a key for displaying a macro pattern. By pressing this button, a signal outputted from the input device 12 is sent to the process computer 1 via the interrupt judgment processing means 15, an interrupt is generated, and the interrupt processing means 19 sends a signal to the process computer 1, which processes the second processing means 4 and the first processing. One of the means 5 is selected depending on the type of signal and is executed.

In this case, the pixel pattern can be input using the character keys 13. In addition, inputting a macro pattern, which is a set of pixel patterns, is possible using the function key 14.
This is done by sending a signal directly to the process computer 1 using the , causing an interrupt to cause the interrupt processing means 19 and the second processing means 4 to execute, thereby writing the macro pattern directly to the refresh memory means 17 as screen data. .

Both pixel patterns and macro patterns can be input with a single operation of pressing a key.

Furthermore, in order to create, add, or change a new pixel pattern in addition to the pixel patterns prepared in advance, the second processing means 4 uses the CR1 display device 11 and the input device 12 to display the pixel pattern on the CJgT screen. The pixel pattern is set by displaying an image enlarged by one pixel on the screen, and then having the user perform an interactive operation to set the pixel pattern by specifying the glowing position of the dot among the 1rI11 elements. It has a function of storing data in the pixel pattern data storage section on the auxiliary storage device 6.

With the functions described above, the second processing means 4 allows the user to use the input device to create an arbitrary image on the 017 screen as shown in 11 in FIG. 4(b). It is possible. The second processing means 4 also allows the user to
It also has a function to save images created on the screen on the auxiliary storage device 6.

In addition to the fixed n'ii (t) mentioned above, the CR1 display screen for process monitoring and control includes display of process data that changes from moment to moment according to the movement of the plant, and the display of abnormalities in process equipment. It is necessary to display a color change (from green to red, etc.) of the image to indicate the second processing means 4.
The data for displaying such a variable image, that is, the data for setting the display position, the number of digits of a numerical value, the limit value for changing the display color, etc., is transmitted through dialogue using the CR1 display device 11 and the input device 12. By operation, the user creates the data and stores it in the variable data storage section 8 on the auxiliary storage device 6.

The above two storage functions of the second processing means 4 create data for process monitoring and control (JT screen display) on the auxiliary storage device.

With the functions of the second processing means 4 described above, the user can directly display the created data on the screen of the CFiT display device 11 using the symbols assigned to the keys of the keyboard input device 12. It is possible to create and change.

On the other hand, the first processing means 5 uses the data created by the second processing means 4 to display the state of the cutting process on the CRT display device 11. The first processing means 5 stores data sent from the process and the data storage section 7.8.9.
The CRT display for process monitoring and control is performed while referring to the data on the screen. FIG. 5 shows an example of a screen created by the second processing means 4 and displayed by the first processing means 5.

When displaying a pattern on a CRT display screen through an input device 12 such as a keyboard, the user can move the marker to a predetermined position on the 017 screen simply by placing it at a predetermined position. A device like this (called a light pen), and a device that allows the marker to be moved in a predetermined direction by tilting the L stick in an appropriate direction.
(joystick) makes it easier to create images.

A simulated data generation means 27 is added as shown in FIG. 6 for creating data simulating the input data from the processing process inside the process computer, and the data created here is processed by the first processing means 5, CR via the input/output control device 10
By displaying and updating on the T screen, it becomes possible to dynamically evaluate the screen display data created by the second processing means 4 without any process input.

Effects of the Invention It becomes possible to easily and quickly create and change the complex and enormous amount of data required for the CR1 display screen for process monitoring and control, and it becomes easy to design and create the optimal screen for plant monitoring. As a result, improvements in plant monitoring performance can be expected, leading to improvements in the reliability of plant operation.
