PLANT ANALYZING SYSTEM
First Claim
1. A plant analyzing system for analyzing a state of a plant based on data obtained from the plant, comprising:
- an accepting section that accepts a definition of a soft-sensor for creating key information used for diagnosing the plant based on the data obtained from the plant;
a storage section that stores the soft-sensor defined through the accepting section;
a monitoring data generating section that generates the key information in real time as data for monitoring the plant based on the data obtained from the plant and using the soft-sensor stored in the storage section;
a monitoring data display section that displays in real time the data for monitoring the plant, generated by the monitoring data generating section, on a screen for monitoring an operation;
a history data accumulating section that accumulates the data obtained from the plant as history data; and
an analyzing data generating section that generates the key information, as data for analyzing a plant state of the past, based on the history data accumulated in the history data accumulating section by using the soft-sensor stored in the storage section.
