Plant monitoring apparatus and plant monitoring method
First Claim
1. A plant monitoring apparatus comprising:
- a process measuring unit configured to store data of a plant;
a warning determining unit operatively connected to the process measuring unit and configured to determine a plurality of warning data to be issued as warnings from a large amount of process data collected by the process measuring unit on the basis of a preliminarily set criterion;
a warning selecting unit operatively connected to the warning determining unit and configured to compare the plurality of warning data with one or more classification criteria;
a display/setting unit operatively connected to the warning selecting unit and configured to display the warning data to an operator through a display processing unit;
a warning criteria database operatively connected to the display/setting unit and configured to access selected data through a warning criteria setting unit; and
a warning criteria supplying unit operatively connected to the warning criteria database and configured to load a warning criteria from the warning criteria database to the warning selecting unit,wherein the warning selecting unit compares the plurality of warning data with one or more classification criteria supplied by the warning criteria supplying unit so as to classify the plurality of warning data, and the warnings are classified into categories according to the classification and the classified warnings are displayed on the display/setting unit, respectively, on different screens for each classification criterion, the different screens being hierarchical screens.

Abstract
A plant monitoring apparatus includes: a process measuring unit; a warning determining unit; a warning selecting unit; a display processing unit; a display/setting unit; a warning criteria setting unit; a warning criteria database; and a warning criteria supplying unit. The warning determining unit determines a plurality of warning data to be issued as warnings from a large amount of process data collected by the process measuring unit on the basis of a predetermined determination criterion. The warning selecting unit compares the plurality of warning data with one or more classification criteria supplied by the warning criteria supplying unit so as to classify the plurality of warning data. Warnings are classified into categories according to the classification and the classified warnings are displayed on the display/setting unit.
