Abstract

PURPOSE:To make an output result of a message easily visible by shifting printing or a display output head position of the message which is outputted in accordance with various input signals, in accordance with a kind and a quality of the message. CONSTITUTION:An information file corresponding to each message is provided on an auxiliary storage device 2, and in this file, printing start position information of each message is inputted in advance. As for a software for outputting a message set to a central processing unit 1, in its message editing part, a printing start position is fetched from the message information file concerned of the auxiliary storage device 2, and in accordance with the fetched printing start position, a null is added to the head of the message. For instance, an output start position of each message is determined so that a message 10 related to an operation and a stop of a plant apparatus, a message 11 related to a fault of the plant apparatus, and a message 12 related to a state and a fault of a computer system are outputted to the left end, the middle stage, and the right end, respectively.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a message output die that outputs changes in the status of plant equipment, operating status of a monitoring and control system, etc. in the form of messages.

[Technical background of the invention and its problems]

The use of electronic computers for plant monitoring and control has become widely used. In such a monitoring and control device, a central processing unit processes equipment operation, stop signals, and failure signals inputted from the plant side, and outputs this information to a message output typewriter, CRT display, etc. Also, changes in the state of the computer system itself are processed by interrupting the central processing unit, and similarly output to a message output typewriter, CRT display device, etc.

FIG. 5 shows the format of a message printed out by the message output die/writer described above.

As is clear from the figure, time 8 is printed on printer paper 7, and then message 9 is printed.

In this case, the message print start position is the same regardless of the type or nature of the message, and various messages are lined up in a mixed manner. This type of print format looks orderly, but as an operator involved in plant monitoring, all messages are lined up without distinction, so 1. It was difficult to use. Particularly when investigating past failures, history, driving history, etc., all messages must be retrieved one after another, and it takes a lot of effort to find the desired message.

[Purpose of the invention]

SUMMARY OF THE INVENTION An object of the present invention is to provide a message output device that makes it easier to see message output results by shifting the print or display head position of messages output in response to various input signals depending on the type and nature of the message. There is a particular thing.

[Summary of the invention]

The present invention provides a message output device that outputs a corresponding message each time various signals are input, in which message content corresponding to each of the various signals is set and a message output position corresponding to each signal content (= each message output position) is set. The present invention includes a table set for each signal, and an editing means that edits and outputs the message content and message output position corresponding to the input signal from the settings of the table when the signal is input. The message output result is made easier to see by shifting the message output start position depending on the type and nature of the message.

[Embodiments of the invention]

Next! One embodiment of the present invention will be described in detail with reference to an embodiment shown in the drawings.

The basic configuration of the plant supervisory control IIIv system is explained in the first part.
Books = Show. 1 is a central processing unit (CPU), main memory 2 is an auxiliary memory, 3 is a process input device, 4 is a plant, 5 is a CRT display device, and 6 is a message output typewriter. Operation, stop signals, and failure signals of equipment in the plant 4 are input to the central processing unit 1 via the process input/output device 3, processed there, and then output to the CRT display device 5 or message output typewriter 6. be done. Also, changes in the state of the computer system itself are processed by interrupts to the central processing unit 1, and similarly, changes in the state of the computer system itself are processed by interrupts to the central processing unit 1.
The message is output to a display device 5 or a message output typewriter 6.

The auxiliary storage device 2 is provided with an information file corresponding to each message, and information on the print start position of each message is input here.

In the software that outputs the message set in the central processing unit 1, in the message editing section, the print start position is retrieved from the message information file in the auxiliary storage device 2, and the print start position is placed at the beginning of the message according to the retrieved print start position. Add spaces.

For example, as shown in Fig. 2, messages 10 regarding the operation and shutdown of plant equipment are output on the left end, messages 11 regarding plant equipment failures are output in the middle, and messages 12 regarding computer system status and failures are output on the left end. Determine the output start position of each message so that

The configuration and operation of the software for performing such output control will be explained in more detail. In Figure 3, 2
2 is a message information table, 23 is a device name table, and U is a phenomenon name table.

In the above equipment name table, the names of each equipment in the plant to be monitored and controlled, such as "Odei Bomb" and "Gensui Bomb" are the names of each equipment in the computer system, such as "CRTol" and "TWol", which correspond to the numbers. It is set. Further, in the phenomenon name table U, names of phenomena of state changes themselves, such as "Ranten" and "Teishi", are set in correspondence with numbers. Furthermore, the message information table 22 includes a point setting area in which input signal points are set by number, a device name area in which the name of the device corresponding to this input signal is set by the number in the device name area n, and a phenomenon indicating a state change. For occurrence and recovery, the phenomenon name area set with the number in the phenomenon name area 24 and the number corresponding to the signal line, for example, when classifying the message output start position as shown in FIG. 2, 1=
Nibrant device operation, stop, 2 = Nibrant device failure,
3 = computer system status/failure and consists of areas set with defined numbers.

Next, one effect will be explained based on FIG. Compare the current status of the plant equipment, the status of the monitoring and control system (hereinafter collectively referred to as 1 status 2) and the previous status. If the signal is caught (step 14), the signal point where the change occurred is known (step 15). After that, the message is edited starting from point positive based on the message information file shown in FIG. That is, as described above, in each area of the message information table 22, the device name positive that should be output when there is a change in the status of each signal point is (point positive of device name table n).

Phenomenon name N when the condition occurs and when it recovers
11 (point positive in phenomenon name table n) and the type of signal are registered in advance in a table format. After editing the time of occurrence of the state change in FIG. 4 (step 16), the device name and phenomenon salt are edited (steps 17 and 18).

Finally, the message output start position is edited based on the signal type (step 19).

In this way, the predetermined message output start position is edited for each output signal. Finally, step 1
The message data edited in steps 5 to 19 is output to a CRT display device or a message output typewriter (step 20). After that, the process returns to step 13 and repeats the above operations. If there is no change in the state in step 14, the process returns to step 13 after the delay time has elapsed (step 21).

With the software configuration described above, the message output shown in FIG. 2 can be realized.

As shown in Figure 2, the edited and output data is classified into information regarding operation and stoppage of plant equipment, information regarding failure of plant equipment, and information regarding changes in the state of the computer system. The location of the required message is easier to understand than the conventional output example shown in FIG.

For example, when an abnormality occurs in a computer V-stem and a history of past messages is required, most of the abnormal messages are related to the operation, stoppage, or failure of equipment. I had to find them one by one from the group. However, it can be easily found by simply looking at the beak on the output side in Figure 2, the output to the right end.

In addition to the above-mentioned classification, the printing position of the message can also be classified for each subsystem of the plant.

If the contents of the message information file, which defines the starting position for each message, can be arbitrarily searched for, changed, and changed using a peripheral device such as a CRT display device, it is possible to search for, change, and change the contents of the message information file, which defines the starting position for each message, to find messages that need attention each time depending on the plant status. It is also possible to determine the output start position of No. 4.

[Effects of the Invention] As described above, according to the present invention, it is possible to output messages at different positions depending on the contents of various signals, and it is possible to easily distinguish the contents of the signals.
