Next, the display management method in this embodiment will be described in detail.

First, data from various devices and devices in the process PR are input to the process signal input device 1, and the abnormality occurrence / recovery detection means 2 changes the state of the input signal, that is, logic "1" to "0" or " The change from "0" to "1" detects the occurrence of an abnormality or the restoration to the normal state. Then, the date and time when these events occur and the item names thereof are stored in the respective areas 3a to 3c of the device state storage memory 3.

At the same time, these data are sent to the display control device 5 via the display data converting means 4, converted into video signals and displayed on the display device 6. As a result, the operator can recognize the occurrence of an abnormality in the process equipment or the recovery thereof. Further, when necessary, an operator issues a print command from the input device 7 to drive the printing device 9 via the print control device 8 and print the same contents as the contents displayed on the display device 6 as a hard copy. .

If an abnormality has occurred in a certain device and no recovery measures have been taken yet, the alarm number display section of the display items shown in FIG. 2 is displayed on the display screen and the hard copy of the display device 6.
Predetermined display output is performed only on 12a, abnormality occurrence date / time display section 12b and item name display section 12c, and other restoration date / time evaluation section
12d, the measure content display section 12e and the measurer name display section 12f are left blank.

In this state, if the operator or countermeasures against the occurrence of an abnormality take some measures for recovery, refer to the following Tables 1 and 2 prepared in advance and refer to the contents of the countermeasures and the countermeasures. The measure number and the measure number corresponding to the name are input from the input device 7.

Here, the data related to the countermeasure content and the name of the countermeasure person is stored in advance in the countermeasure information storage memory 11,
Measure numbers and measure numbers corresponding to these items are also stored in the measure information storage memory 11 as a table, and the first table and the second table can be displayed on the display device 6 in response to a command from the input device 7. This is suitable for input operation. It is of course possible to prepare the above Tables 1 and 2 as documents.

After that, the operator recognizes the number (for example, "1") of the alarm number in the display screen 6'for which the countermeasure is taken, and operates the ten key 14 provided on the input device 7 to input the alarm number in the input field 6 ". At the same time, enter Tables 1 and 2 above.
By referring to the table, the corresponding countermeasure number (for example, "2") and the countermeasure number (for example, "1") are similarly input into the input field 6 "by operating the ten keys 14.

Next, when the registration key 15 provided on the input device 7 is operated, the countermeasure content corresponding to the countermeasure number "2" stored in advance in the countermeasure information storage memory 11 (in the example of Table 1, "repair request completed" )) And the name of the measurer corresponding to the measurer number “1” (“Takahashi” in the example of Table 2) is read by the data read / write means 10, and these data are stored in the device state memory. The countermeasure content storage area 3d and the countermeasure person name storage area 3e of the memory 3 are respectively written in real time.

At the same time, the above-mentioned countermeasure content and the name of the countermeasure person are displayed on the countermeasure content display portion 12e and the countermeasure person name display portion 12f of the display item 12A on the display screen as shown in FIG. 5 via the display data converting means 4, respectively. Will be done. The updated display contents can be printed by the printing device 9 in response to a print command from the input device 7. Note that 12B in FIG. 5 is a display item according to another display example.

In this way, the display items 12A, 12B, ... to which the countermeasure content and the name of the countermeasure person are added are always stored in the device state storage memory 3, so that, for example, by another operator who has been replaced. In response to a command from the input device 7, the alarm history can be displayed on a display device or printed out on a printing device, and it is not necessary to communicate the device status using a verbal or takeover diary at the time of handover. For example, from the display item 12A in Fig. 5, the operator "Takahashi" has requested repairs due to the failure of the No. 1 pump, but the operator after handing over easily recognizes that the repairs have not been completed yet. It will be possible.

In addition, in this embodiment, the case where the operator additionally inputs only the content of the countermeasure and the name of the countermeasure person as the countermeasure information for restoration has been described, but the present invention is not limited to this.
It can also be applied to the case of additionally inputting other countermeasure information such as the scheduled recovery time and the cause of the abnormality occurrence.

(Effects of the Invention) As described in detail above, according to the present invention, the contents of the recovery measures taken by the operator and the name of the measurer, etc. are stored for various abnormalities of equipment and the like that occurred during plant operation. At the same time, they can be recognized at a glance by the subsequent output request of the alarm history, so that the complexity of information transmission by the oral or the transfer diary as in the past is eliminated, and the burden on the operator is greatly increased. It has the effect of being reduced.

At the same time, smooth operation of the plant is possible without leakage of inherited items, and when an abnormality of the same type occurs, it is possible to take prompt action by referring to the alarm history and referring to past countermeasures. It has various effects such as
