VIRTUAL SENSOR SYSTEM AND METHOD

摘要

A method is provide for providing sensors (130) for a machine (100). The method may include obtaining data records including data from a plurality of sensors (140, 142) for the machine and determining a virtual sensor corresponding to one of the plurality of sensors. The method may also include establishing a virtual sensor process model (404) of the virtual sensor indicative of interrelationships between at least one sensing parameters (402) and a plurality of measured parameters (406) based on the data records and obtaining a set of values corresponding to the plurality of measured parameters. Further, the method may include calculating the values of the at least one sensing parameters substantially simultaneously based upon the set of values corresponding to the plurality of measured parameters and the virtual sensor process model and providing the values of the at least one sensing parameters to a control system (120).
