Abstract

PURPOSE:To erase an alarm message automatically by storing the life time of the message when the alarm message is displayed on a CRT display device and erasing the message display the stored time later. CONSTITUTION:A task A1 sends an alarm output request 1 to an alarm processing task B and also passes alarm information. This alarm information consists of an alarm display output destination, life information, and the alarm message. The alarm processing task B outputs the alarm message 6 to an output-destination display device CN and also stores the life information in a storage device D. Further, the task B updates the information on the device on the device D while counting down the life information on the device D by one at each time to 0 at a constant period by timer actuation 3 and requests the CRT display device CN to erase the alarm display whose life comes to the end when the subtraction result equals 0. Consequently, the message is erased automatically.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to alarm messages, and particularly to display processing suitable for effectively displaying operator guidance on a CRT display device.

[Conventional technology]

When displaying an alarm message, if the message is not updated and one message is displayed for a long time, for example, if an error message is displayed for more than 8 hours, the following problems occur. The operator has to repeatedly check the system every time he sees an abnormal message, which places a burden on the operator. In addition, even though the abnormal condition displayed in the message has already been recovered, an operator other than the operator who performed the error recovery may make a wrong decision and perform the error recovery operation again.
There are problems that cause operator errors.

As a conventional technique for solving this problem, there is the following method.

(1) Method of adding and displaying time data to a message. In this method, the operator determines whether a displayed message is valid or invalid by looking at the time in the message.
However, with this method, if a message is displayed beyond the time display information (for example, if the display information is hour and minute information and the message is displayed for more than 24 hours), the operator's judgment is make a mistake

Furthermore, if the time information is set as year, month, day, hour, minute, and second, there is a problem that the message becomes troublesome to read and the original message display area is wasted.

(2) Delete the alarm message in response to the operator's screen deletion request. In this method, each time a message is displayed, the operator requests deletion of the display and deletes the message.

However, with this method, there is a problem in that the operator must carry out the message deletion operation, which places a troublesome burden on the operator.

(3) A method of displaying alarm messages and erasing them one by one after a certain period of time has elapsed.

However, with this method, relatively unimportant messages such as OK messages for CRT keyboard input, as well as system-important messages such as file processing errors, are displayed for the same amount of time, leading to the problem that messages that should not be erased may be erased. be.

Incidentally, related technologies of this type include, for example, JP-A-61-112212 and JP-A-59-15455.
Publication No. 8, etc. may be mentioned.

[Problem to be solved by the invention]

The above-mentioned conventional technology does not give sufficient consideration to the method of erasing a message display that becomes invalid over time after an alarm message is displayed, and requires manual intervention by an operator to erase the message. Another problem was that it was not possible to specify the effective display time of each message.

An object of the present invention is to include life information in the display of alarm messages so that after the effective display time of each message has elapsed,
The purpose is to enable automatic message deletion. [Means for solving the problem] The above object is achieved by storing the lifespan of the message when displaying the alarm message on the CRT display device, and erasing the alarm message display after this time has elapsed. Ru.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

<Embodiment 1> Figure 6 shows the format of a screen displayed by a CRT display device. FIG. 2 shows a processing block diagram in a computer system consisting of M CRT display devices BC1 to C)4 having the screen format shown in FIG. In FIG. 2, task A1 issues alarm output request 1 to alarm processing task B, and also passes alarm information (reference numeral 4). This alarm information consists of an alarm display output destination N, life information X, and an alarm message Y, as shown in FIG. In FIG. 2, alarm processing task B outputs alarm message 6 to the output destination CRT display device CN (reference numeral 2).
At the same time, the life information X is stored in the storage device END. This storage device D has a memory structure as shown in FIG. 4, and stores life information at a position XN corresponding to the output destination N (reference numeral 5).

Furthermore, task B updates the life information X1... The subtraction result becomes O, and the CRT display device CN is requested to erase the alarm display whose life has expired.

CRTCN from task A2 before the display life of CN expires.
When there is a new request to output an alarm message, task B outputs a new message to C R T C N and changes the lifespan information XN of D to the new lifespan information.

Embodiment 2 This embodiment describes the operation of task B and the storage device 1i1 in Embodiment 1.
This is an example in which the storage information of D is changed. The screen format of the CRT display device and the processing configuration are the same as in the first embodiment.
They are shown in Fig. 2 and Fig. 2, respectively.

In FIG. 2, task B receives alarm message output request 1 from task A1, receives alarm information as shown in FIG.
Request alarm output from N and store hemorrhoid information and alarm message data! Store in D. Here, memory device!
D is life information XN.D as shown in FIG. The structure is such that N and alarm message YN, N are one record, and task B stores life information X and message Y as one record.
,I and YN,1. Note that the memory structure of the storage device D has a first-in, first-out structure for the display output destination N. This means that, as shown in Fig. 1, if a request for alarm output a2 is made to the display area before the alarm message a1 currently displayed on the CRTCN reaches the end of its lifespan,
information of al XN, 1 and YN, t as XNt z and YN, z
and stores the information of am in XN,1 and YN,1. And the alarm message display of C R T C N is from a1 to 82, alarm message a2
(The lifespan information of XNth is shown in Example 1.
Similarly, if the life of a1 (updated by task B using periodic timer 3) remains, the information X? of az? I,
2 and Ys, 2 is shifted to X++, x and Ys, 1 and Yl
1, 1 alarm message is output to CRTCN. As a result, when the life of the message ax ends, the message a1 is displayed on the CRTCN again.

In the above two embodiments, each CRT display device has one
Although the alarm message output area is set to 1, since life management is performed in accordance with the CRT display output destination, the same process can be performed for any number of display output areas.

In the second embodiment, there is an effect that the life time can be displayed without losing important messages.

〔Effect of the invention〕

According to the present invention, by giving the alarm message display a limited lifespan, it is possible to automate the erasure of messages that had previously been done by the operator, and to continue until the conventional display is updated for messages that are no longer needed due to the passage of time. This has the effect of reducing the annoyance of the operator caused by seeing and making decisions over and over again with the same message, and preventing the operator from making erroneous decisions due to the display of unnecessary messages. Furthermore, since the lifespan can be defined for each alarm message, the operator can be made aware of the importance of each message, which has the effect of improving the reliability of alarm messages.
