REGIONAL BIG DATA IN PROCESS CONTROL SYSTEMS

摘要

A regional big data node oversees or services, during real-time operations of a process plant or process control system, a respective region of a plurality of regions of the plant/system, where at least some of the regions each includes one or more process control devices that operate to control a process executed in the plant/system. The regional big data node is configured to receive and store, as big data, streamed data and learned knowledge that is generated, received, or observed by its respective region, and to perform one or more learning analyses on at least some of the stored data. As a result of the learning analyses, the regional big data node creates new learned knowledge which the regional big data node may use to modify operations in its respective region, and/or which the regional big data node may transmit to other big data nodes of the plant/system.

主权项

1. A regional big data node for supporting big data in a process plant controlling a process, the regional big data node comprising:
a network interface that communicatively connects the regional big data node to one of a plurality of regions of the process plant, the one of the plurality of regions comprising a plurality of local big data nodes, each of which transmits, in real-time, data generated from the control of the process by the process plant as the process is being controlled in real-time; a big data storage area comprising one or more tangible, non-transitory, computer-readable storage media configured to store regional big data; a big data receiver configured to receive the data transmitted by the plurality of local big data nodes and received at the regional big data node via the network interface, and store the received data in the big data storage area; and a big data analyzer configured to:
perform a learning analysis on at least a portion of the regional big data;generate learned knowledge based on a result of the learning analysis; andcause a change in operations of at least a portion of the process plant based on the result of the learning analysis, including causing the learned knowledge to be transmitted to a recipient big data node corresponding to the at least the portion of the process plant.
