Process control of an industrial plant
First Claim
1. A system for controlling an industrial plant, the system comprising:
- automatic control equipment comprising a plurality of measurement sensors for sensing predetermined variables associated with at least one component of the industrial plant, the sensors generating measured data relating to operation of the at least one component of the industrial plant;
a database containing the measured data and observational data obtained by plant personnel and relating to an operational state of the at least one component of the industrial plant; and
a processor in communication with the automatic control equipment and the database for receiving the measured data from the sensors of the automatic control equipment and the observational data from the database, the processor;
quantifying a level of disorder of the measured data;
computing a raster of the level of disorder of the measured data;
determining a state of the at least one component of the industrial plant based at least in part upon the raster of the level of disorder of the measured data;
controlling the automatic control equipment based on the determined state; and
integrating the measured data and the observational data to build a description of a process condition over time of the at least one component.

Abstract
A system 10 for controlling an industrial plant 12 comprises automatic control equipment 14 comprising a plurality of measurement sensors 16 for sensing predetermined variables associated with components of the industrial plant 12. The sensors 16 generate measured data relating to operation of the components of the industrial plant 12. A database 20 contains operational data, including observational data, regarding the industrial plant 12. A processor 18 is in communication with the automatic control equipment 14 and the database 20 for receiving the measured data from the sensors 16 of the automatic control equipment 14 and the operational data from the database 20. The processor 18 manipulates the measured and operational data to provide an evolving description of a process condition of each component over time, along with output information relating to operational control of the industrial plant 12 and for updating the database 20.

11. A method of controlling an industrial plant, the method comprising:
-
monitoring operation of at least one component of the industrial plant by a plurality of sensors forming part of automatic control equipment; transferring measured data from the sensors and observational data relating to operation of the industrial plant to a processor, the observational data being obtained by plant personnel and relating to an operational state of the at least one component; accessing a database containing the measured data from the sensors and the observational data relating to operation of the industrial plant, as periodically updated by the processor; quantifying, automatically with the processor, a level of disorder of the measured data; computing, automatically with the processor, a raster of the level of disorder of the measured data; determining a state of the at least one component of the industrial plant, automatically with the processor, based at least in part upon the raster of the level of disorder of the measured data; controlling the automatic control equipment based on the determined state; and integrating, automatically with the processor, the measured data and the observational data to build a description of a process condition over time of the at least one component of the industrial plant. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)
