Alarm display apparatus and alarm display method

摘要

An alarm display apparatus includes an acquisition module, a plant simulation module, a prediction module, an actual measurement alarm determination module, an estimation alarm determination module, a prediction alarm determination module and a display module. The display module displays, on the same screen, an actual measurement alarm information outputted from the actual measurement alarm determination module, an estimation alarm information outputted from the estimation alarm determination module and an prediction alarm information outputted from the prediction alarm determination module.

1. An alarm display apparatus for displaying alarm information indicating a generation state of alarms based on information acquired from a plant, comprising:
an acquisition module configured to acquire actual measurement values of data obtained from the plant; a plant simulation module configured to simulate a current state of the plant based on the data obtained from the plant to thereby output current estimation values of data of the plant; a prediction module configured to predict a future state of the plant based on the estimation values outputted from the plant simulation module to thereby output prediction values of data of the plant; an actual measurement alarm determination module configured to compare the actual measurement values acquired by the acquisition module with a threshold value to thereby output actual measurement alarm information based on a result of the comparison between the actual measurement values and the threshold value; an estimation alarm determination module configured to compare the estimation values outputted from the plant simulation module with a threshold value to thereby output estimation alarm information based on a result of the comparison between the estimation values and the threshold value; a prediction alarm determination module configured to compare the prediction values outputted from the prediction module with a threshold value to thereby output prediction alarm information based on a result of the comparison between the prediction values and the threshold value; and a display module configured to display, on the same screen, the actual measurement alarm information outputted from the actual measurement alarm determination module, the estimation alarm information outputted from the estimation alarm determination module and the prediction alarm information outputted from the prediction alarm determination module, wherein when the actual measurement alarm information is output from the actual measurement alarm determination module or the estimation alarm information is output from the estimation alarm determination module, the display module displays the output actual measurement alarm information or the estimation alarm information, instead of the prediction alarm information displayed with respect to alarm corresponding to the actual measurement alarm information or the estimation alarm information.
