Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a warning device that uses a CRT display device or the like to display and warn the occurrence and disappearance of various alarms occurring in a system.

[Prior art]

FIG. 1 is a block diagram showing an example of a conventional warning device for a plant monitoring device. In the figure, (1; is a plant device, 121 is a sensor for monitoring and displaying the operation of each part of the plant device, (3) is a process input/output device for inputting and outputting information from this sensor, and (41 is an industrial computer) , (5) is a CRT display device for displaying and warning data from this industrial computer.

FIG. 2 is a display screen diagram showing an example of the display of this CRT display device (51), in which (10) is the title section, (111 is the time of occurrence, (12) is the name of the device where the message is generated, ( 131 is an alarm message section, and C14 is a measured value section.

In the alarm device configured as described above, the status of each part of the plant device (1) is detected by the sensor 121, converted into an electrical signal, and sent to the industrial computer (4) via the process input/output device (3). ).

The industrial computer performs an abnormality check process, selects a message corresponding to the abnormality from the accumulated message group of the entire plant equipment (1), and displays the message in the title section (10) of the CRT display device (5) in the order of occurrence. ), the alarm monitor section displays the occurrence time and the device name section (121, alarm message section 11.).
31, and are displayed in the order of measured value section CI4.

By displaying only the generated messages in this way, it is possible to deal with a huge number of alarm output points on a compact display screen, and by turning several pages, it can correspond to most plant conditions. can.

However, as mentioned above, alerts are displayed in chronological order, so it is not certain where a particular message will appear on the screen.
Operators have to judge the situation by reading the messages, and there are also disadvantages in that it is not possible to identify patterns based on the combination of multiple alarms. CR in the nest
The scale did not fully take advantage of the compactness of the T-display, and it also had the disadvantage of losing some of the features of the alarm systems that existed before the advent of CRTs and displays.

[Outline of the invention]

This invention was made in order to eliminate the above-mentioned drawbacks of the conventional device.The entire wheel set item is arranged in advance on a CRT screen so that the whole can be grasped, and when a new alarm occurs or disappears, etc. The purpose of this is to provide a device that allows operators to easily make decisions and operate by enlarging a portion of the screen if necessary.

[Embodiments of the invention]

FIG. 3 is a comprehensive report display screen diagram showing one embodiment of the present invention, where 6 and tttn indicate the same or equivalent parts as the same reference numerals in FIG. 2. In the figure, (20) is a plant Display items for each system within the device (2 are alarm items.

FIG. 4 is a partial alarm display screen diagram showing an example of a partially enlarged display screen of FIG. 3. FIG.

Abnormalities detected by the sensor (2) and the industrial computer (41) are displayed at specific positions on the CRT display device (5) as shown in Figure 3, and are further reflected by flickering and discoloration of the corresponding parts on the screen. When the operator learns of this abnormality, it is difficult to read the alarm item names on the batch report screen in Figure 3 because the CRT display area is limited to 9.
By specifying the center point of the pressurizer system in step 0), it is possible to enlarge it as shown in FIG. 4 and display the alarm generation part in detail so that it is easy to see.

In addition, in addition to magnification, it is also possible to use parallel movement etc. to make the display easier to see.In this way, operators can use magnification and -parallel movement to accurately display the status of their information using a CRT display device with a limited screen range. can be grasped.

In the above embodiment, the alarm item display is shown in Japanese with a frame, but the alarm item may be displayed without a frame, or the alarm item may be a figure, a symbol, a Roman character, or the like.

Further, in the above embodiment, a case was described in which a CRT display device (5) was used, but other types of display devices, such as LEI
) & Indications, the same effect can be expected even with a liquid crystal display.

〔Effect of the invention〕

As explained above, in this invention, the alarm items are always displayed at a specific display position on the screen, so that the operator can quickly grasp the alarm items in a pattern. Furthermore, the operator can enlarge or reduce the display contents as necessary, thereby enabling the operator to recognize accurate warnings and make quick decisions.
