Abstract

PURPOSE:To improved throughput by searching for only a bit which is needed for displaying a screen when a signal for display state is input and then outputting a needed signal to a display part through a man-machine analysis part of an input system when it is judged that the state changed. CONSTITUTION:An external information from a transmission path 1 is taken into an input part 2 and a screen task is started. A state change detection part 3 judges a specified pit which is needed for displaying screen according to a signal which is input to the input part 2. When it is judged that the state changed as a result, a message task 9 is started and is output to a printing part 16 and then a message is output to a first man-machine analysis part 4. The analysis part 4 examines whether a state change is generated within a flicker pattern and the screen, the state change is displayed on a display 15 when the state change occurs and then is reported to an operator. The operator operates a keyboard, etc., as needed and then inputs a signal to a display input part 6. When a second man-machine analysis part 7 reads it, it outputs the signal to the analysis part 4. The analysis part 4 displays a state according to the screen display input operation and at the same time stops flickering.

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a data processing device in a monitor display control device or the like.

[0002]

2. Description of the Related Art As a monitor / display control device for a power system or the like, there has been proposed a device for monitoring the state of the system by computer control and displaying this state with a message.
The monitoring display control device is configured as shown in FIG. 3, but generally, an input / output unit 11 for inputting a status display signal such as a failure, operation, or stop of the power system, a memory 1 are input.
2, an arithmetic processing unit 13, a storage unit (hard disk) 14,
The display unit 15 and the printing unit 16 such as a printer are included.

FIG. 4 shows the basic processing flow.

The state change detection unit 22 detects a state change from the input signal for state display introduced through the input / output unit 11. Next, by starting the message display task,
The man-machine analysis unit 23 outputs the message registered in the hard disk 14 to the display unit 15 via the display output unit 26 and displays it in the message area of the CRT screen, and outputs it to the printing unit 16 via the message task 24. .. Also, the message file creation task is started,
The state change is written to the hard disk in the form of a tag number corresponding to the message content together with the time when the state change occurred. The message list is displayed by operating the corresponding function key.

With this processing, the number of monitoring points is expanded by expanding the area of each unit, improving the expandability and distributing the arithmetic processing units for each equipment to improve the processing capacity.

[0006]

As described above, the prior art is as follows.
It is a task for each function, and moreover, unmanned plant equipment,
The number of monitoring points is increasing due to the monitoring of details by the introduction of predictive maintenance and improvement of the dependency on the monitoring and control device by driving support. For this reason, in the event of a power failure due to an abnormality in electrical equipment, the status changes occur all at once, and in the past, processing could not be completed and a delay occurred, lacking real-time performance. There are some cases where it is impossible to constantly monitor.

[0007]

According to the present invention, in a monitor display control device for monitoring and displaying a change in the state of a plant, pattern data for each screen display of a display unit is stored in a storage unit. In addition, the man-machine analysis unit is divided into an input system and a control system, and the state change detection unit is configured to search only the bits necessary for screen display at the time of detection.

[0008]

[Function] When a signal for status display is input, the status change detection unit searches only the bits necessary for screen display, and if it is determined that there is a status change, it is necessary for screen display through the man-machine analysis unit of the input system. Output signals to the display unit.

On the other hand, the operation signal input from the operator is input to the man-machine analysis section of the control system for determination, and the man-machine analysis section of the input system is controlled to stop the flicker on the display section. To do.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The basic construction of the monitor display control apparatus according to the present invention is constructed as shown in FIG. 3, but the function for its processing is constructed as shown in FIG.

Reference numeral 1 is a transmission line, 2 is an input section, and this input section 2
For example, a status display signal such as a failure, operation, or stop of the power system is displayed in bits, and is input in a word structure as shown in FIG. A state change detection unit 3 searches only the bits required for screen display among the external information obtained from the transmission unit 1. The first (input system) man-machine analysis unit 4 determines the priority of screen display and the order of important display. A display output unit 5 and a display input unit 6 output an operation signal from an operator to the second (control system) man-machine analysis unit 7. Reference numeral 8 is an output unit, and 9 is a message task.

3 to 7 indicate screen tasks, which are prepared for each screen unit. That is, the screen display contents are provided exclusively for electric power equipment, mechanical equipment, plant equipment, etc., and their control and display contents are determined and patterned and stored in the hard disk.

Next, the operation will be described.

External information from the transmission line 1 is taken into the input unit 2 and the screen task is activated. The state change detector 3
From the signal input to the input unit 2 as shown in FIG. 2A, only the designated bit (hatched portion is a state change bit) required only for screen display is determined as shown in FIG. As a result, when it is determined that the state is abnormal, the arithmetic processing unit 13 refers to the memory contents, activates the message task 9, outputs the message registered in the hard disk to the printing unit 16 and prints it out, and 1 to the man-machine analysis unit 4.

The man-machine analysis unit 4 checks whether or not a flicker pattern necessary for screen display and a state change in the screen have occurred. Then, when a state change occurs, the display output unit 5
A display signal is output to the display unit 15 through the display unit to display the signal to notify the operator of the occurrence of the state change. The operator inputs an operation signal to the display input section 6 by operating a keyboard, a light pen or the like as necessary.

When the second man-machine analysis section 7 reads the operation signal input to the display input section 6, the second man-machine analysis section 7 inputs a signal from the operator input to the first man-machine analysis section 4 by the screen display input operation. Is output. Therefore, the first
The man-machine analysis unit 4 displays the state at the time of input by the screen display input operation from the operator,
The flicker is stopped by receiving information from the flicker stop operation.

Further, the second man-machine analysis section 7 outputs an input operation signal for screen display from the operator to the output section 8 and also to the state change detection section 3. The state change detection unit 3 obtains the operation information from the man-machine analysis unit 7 of the control system, and distinguishes whether or not the state of the device changes depending on the operation state and determines whether or not to output the message task.

[0018]

As described above, according to the present invention, the status change information is patterned on the display unit for each screen display, and the CR is applied when the status change is determined.
The T screen display unit is selected in bit units, and it is divided into an input system and a control system for each screen task, so the data processing speed can be increased, and even if all state changes are input at the same time, it is displayed. It can be displayed in real time in the screen area, and the control operation can be performed from the display screen regardless of the status change processing of other screen tasks. For example, even if the message is automatically returned at the site and does not remain on the screen display, the message can be generated and the recovery printing can be performed, and even if there is a simultaneous input, the important items can be displayed for each screen.

Further, by patterning the dedicated display and control for each equipment for each display screen, if the display screen is created, it can be set for each screen and can be created for each equipment as well, so that it is easy to use and is user-level. There is an effect that it is possible to create.
