Abstract
A system processes historical facility data that relate to facility states and modes of operation. The historical facility data are clustered into groups representing the facility states and the modes of operation. The groups are used to determine a current state and mode of the facility. When the facility is in a normal state, the system determines whether an event in the facility is an abnormality. If an abnormality is identified, the system transmits a signal indicating the abnormality.
Claims18
A process comprising:
- receiving by a computer processor, facility data relating to states of a facility and operating modes of the facility;
- clustering, by the computer processor, the facility data into groups representing facility states and facility operating modes, thereby generating a plurality of clusters relating to the facility states and facility operating modes;
- using, by the computer processor, the plurality of clusters to determine a state and mode of the facility;
- determining, by the computer processor, when the facility is in a normal state, whether an event in the facility comprises an abnormality;
- transmitting, by the computer processor, a signal to a computer display device indicating the abnormality;
- regenerating, by the computer processor, the plurality of clusters when one or more new modes of the facility are identified;
- using, by the computer processor, the regenerated plurality of clusters to determine, when the facility is in a normal state, whether an event in the facility comprises an abnormality;
- and
- transmitting, by the computer processor, a signal to the computer display device indicating the abnormality;
- determining, by the computer processor and the plurality of clusters, when to commence a normal shutdown;
- transmitting, by the computer processor, a signal to the computer display device indicating when to commence the normal shutdown;
- wherein each of the plurality of clusters relates to a particular facility state and a particular facility operating mode;
- and
- wherein each of the plurality of clusters comprises descriptors relating to the particular facility state and the particular facility operating mode.

A device comprising:
- a computer processor;
- memory;
- and
- one or more programs stored in memory, the one or more programs including instructions for performing a process comprising:
- receiving, by the computer processor, facility data relating to states of a facility and operating modes of the facility;
- clustering, by the computer processor, the facility data into groups representing facility states and facility operating modes, thereby generating a plurality of clusters relating to the facility states and facility operating modes;
- using, by the computer processor, the plurality of clusters to determine a state and mode of the facility;
- determining, by the computer processor, when the facility is in a normal state, whether an event in the facility comprises an abnormality;
- transmitting, by the computer processor, a signal to an operator or a computer display device indicating the abnormality;
- determining, by the computer processor and the plurality of clusters, when to commence a normal shutdown;
- and
- transmitting, by the computer processor, a signal to the computer display device indicating when to commence the normal shut down;
- wherein each of the plurality of clusters relates to a particular facility state and a particular facility operating mode;
- and
- wherein each of the plurality of clusters comprises descriptors relating to the particular facility state and the particular facility operating mode.
12 more elements
A non-transitory computer-readable storage medium comprising one or more programs for execution by one or more processors of a device, the one or more programs including instructions which, when executed by the one or more processors, cause the device to perform a process of:
- assessing, by the one or more processors, facility data relating to states of a facility and operating modes of the facility;
- processing, by the one or more processors, the facility data using a trained machine learning model, the trained machine learning model trained using historical facility data comprising a plurality of facility states and facility operating modes, to determine a state and mode of the facility;
- using, by the one or more processors, the trained machine learning model to determine, when the facility is in a normal state, whether an event in the facility comprises an abnormality;
- determining, using the trained machine model, when to commence an emergency shutdown;
- and
- transmitting, by the one or more processors, a signal to a computer display device indicating when to commence the emergency shutdown.
