Abstract
A method is provided for a virtual sensor system. The method may include obtaining data records associated with a plurality of input parameters and at least one output parameter and adjusting values of the input parameters based on autocorrelation of respective input parameters. The method may also include reconfiguring the input parameters based on cross-correlation of respective input parameters relative to the output parameter and establishing a first virtual sensor process model indicative of interrelationships between the adjusted and reconfigured input parameters and the output parameter.
Claims25
A computer-implemented method for a virtual sensor system, comprising:
- obtaining data records associated with a plurality of input parameters and at least one output parameter;
- adjusting, by at least one computer processor, values of the input parameters based on results from analyzing respective input parameters, the adjusting including autocorrelating the respective input parameters;
- reconfiguring, by the at least one computer processor, the input parameters, including cross-correlating respective autocorrelated input parameters with the output parameter;
- and
- establishing a first virtual sensor process model indicative of interrelationships between the correlated and cross-correlated input parameters and the output parameter.
A computer system for establishing a virtual sensor system, comprising:
- a database configured to store information relevant to the virtual sensor system;
- and
- a processor configured to:
- obtain data records associated with a plurality of input parameters and at least one output parameter;
- adjust values of the input parameters based on autocorrelation of respective input parameters;
- reconfigure the input parameters based on cross-correlation of respective input parameters relative to the output parameter;
- and
- establish a virtual sensor process model indicative of interrelationships between the autocorrelated and cross-correlated input parameters and the output parameter.
