Abstract: Measurement exchange networks and protocols to exchange measurements of a parameter amongst devices (e.g., IoT devices), select the best measurement(s), accuracy/precision-wise, and determine a process variable for a control system based on the selected best measurement(s). A device may select a peer-provided best measurement to output as the process variable in place of a local measurement, and/or compute the process variable from multiple best measurements (e.g., local and/or peer-provided measurements). Metadata may be used to select a measurement(s) and/or to increase reliability/trust of exchanged data. In this way, each device of an exchange group/network may obtain the highest measurement accuracy of all available collocated sensors with little or no additional processing or cloud connectivity.

Abstract: A technique for cognitive protection of a system can include digital and analog sensors to measure or calculate operational parameters of a system. Digital sensors may be used to determine measured or primary operational parameters. The analog sensors are used to measure analog sensor information related to operation of the system. Analog sensor information that is measured may be used to calculate secondary operational parameters that includes the same operating parameters as the primary operational parameters. Lockstep analysis may be used to compare the primary operational parameters with the secondary operational parameters so as to determine a discrepancy in the operational parameters in the system.
