Patent number: 8224468Abstract: A method is used for providing sensing data to a control system of a machine. The method may include providing a plurality of virtual sensors, each of which may have a model type, at least one input parameter, and at least one output parameter. The method may also include integrating the plurality of virtual sensors into a virtual sensor network; determining interdependencies among the plurality of virtual sensors; and obtaining operational information of the plurality of virtual sensors. Further, the method may include recording measurement data and performance information of the virtual sensor network and the plurality of virtual sensors; and generating one or more calibration certificate of the virtual sensor network based on the operational information, the measurement data, and the performance information.Type: GrantFiled: July 31, 2008Date of Patent: July 17, 2012Assignee: Caterpillar Inc.Inventors: Anthony J. Grichnik, James Mason, Tim Felty

Patent number: 7917333Abstract: A method for providing a virtual sensor network based system. The method may include obtaining project data descriptive of a virtual sensor network to be used in a control system of a machine; establishing a virtual sensor network including a plurality of virtual sensors based on the project data. Each virtual sensor may have a model type, at least one input parameter, and at least one output parameter. The method may also include recording model information, measurement data, and performance information of the virtual sensor network including the plurality of virtual sensors; creating one or more calibration certificates of the virtual sensor network including a plurality of virtual sensors based on the model information, the measurement data, and the performance information; and generating a documentation package associated with the virtual sensor network.Type: GrantFiled: August 20, 2008Date of Patent: March 29, 2011Assignee: Caterpillar Inc.Inventors: Anthony J.

Publication number: 20090293457Abstract: A method is provided for a selective catalytic reduction (SCR) system for reducing a pollutant emission level in exhaust gas of an engine on a machine. The method may include providing a plurality of virtual sensors each having a model type, at least one input parameter, and at least one output parameter. The plurality of virtual sensors may include a first virtual sensor for measuring an emission level of a first component the pollutant and a second virtual sensor for measuring an emission level of a second component the pollutant. The method may also include integrating the plurality of virtual sensors into a virtual sensor network; operating the virtual sensor network to provide the first component emission level and the second component emission level; and calculating a ratio between the first component and the second component based on the first component emission level and the second component emission level.Type: ApplicationFiled: May 30, 2008Publication date: December 3, 2009Inventors: Anthony J.

Patent number: 7593804Abstract: One aspect of the present disclosure includes a method for a control system of a machine. The method may include establishing a virtual sensor model indicative of interrelationships between at least one sensing parameter and a plurality of measured parameters related to the machine. The method may also include obtaining data and function information representing the virtual sensor model and converting the data information into fixed-point representation. Further, the method may include converting the function information into fixed-point representation and loading the converted fixed-point representation of data information and function information in the control system such that the control system uses the virtual sensor model in fixed-point arithmetic operation.Type: GrantFiled: October 31, 2007Date of Patent: September 22, 2009Assignee: Caterpillar Inc.Inventors: Anthony J.
