For example, in FIG. 7, the items in which the alarm occurrence location and the cause of the alarm display are common are items in which the vibration detector circuit is common to the two alarm displays. The fault tree factor analysis list for the common both alarm displays is configured so that the relation is maintained, and the factor investigation items 48 generated from both the fault tree factor analysis lists are arranged.
By configuring so that the cause can be identified based on both fault tree factor analysis lists by inputting a single survey result, the cause of the alarm can be identified more reliably.

Further, as shown in FIG. 8, the factor investigation items generated from the fault tree factor analysis list based on the two alarm displays are arranged in a matrix, and the alarm occurrence and the factor investigation of two or more generated alarm displays are arranged. Arrange items that have duplicate items, prioritize the survey priorities in descending order of the number of factor investigation items, investigate in the order of the priorities, and enter the measured values and confirmation results This enables early detection of the cause of the alarm.

Further, the number of occurrences of the past alarm causes is stored, and the stored past alarm cause data is also taken into consideration at the same time, thereby further expediting the pursuit of the cause. That is, in FIG. 8, since the factor investigation items related to the vibration detector circuit overlap with the two alarm display contents, the investigation priority of the factor investigation from the factor 9 to the factor 12 of the vibration detector is first given. It is positioned. Factor 1
As for item 2, assuming that the number of times of occurrence of the alarm has been one in the past, the factor 12 among the factors 9 to 12 has the highest investigation priority, thereby improving the speed of the cause identification.

As described above, a method of arranging factor investigation items for pursuing causes at the time of displaying a plurality of alarms and determining an investigation priority can be realized by using alarm processing means as shown in FIG. In FIG. 9, the same parts as those in FIG. 1 are denoted by the same reference numerals, and the detailed description thereof will be omitted.

The difference between the other embodiment of the present invention shown in FIG. 9 and the embodiment of FIG. 1 is that the alarm cause specified by the cause specifying unit 25 is stored in the factor history data unit 33. The factor history data section 33 is connected to the alarm factor estimation section 20 and the factor investigation data section 23. The alarm cause specified by the cause specifying unit 25 is stored for each alarm cause specified in the fault tree factor analysis list. An alarm is displayed on the alarm display unit 202 of the centralized monitoring and control apparatus 101, and the fault tree factor analysis list data extracted from the factor estimation data unit 21 by the alarm factor estimating unit 20 based on the displayed coordinates is described above. The cause is transferred to the factor history data unit 33, the number of occurrences of the past alarm cause of the corresponding estimated cause and the cause is searched, and the search result is transferred to the cause investigation data unit 23. In the factor investigation data section 23, the factors are input in the past factor occurrence frequency column of the matrix for organizing the related factors shown in FIG. 8 as conditions for selecting the priority of the factor investigation.

Further, a plant data section 34 is provided to store data such as various performances, effective periods, periodic inspection times, and replacement times of various devices and machines constituting the plant and instrumentation monitoring devices. By using it together with the extraction of the alarm factor investigation item in the factor investigation data section 23, it is used as a judgment material at the time of identifying the alarm factor, so that the early detection of the alarm factor identification when displaying a large number of alarms of a large-scale plant is performed.
