Abstract
Virtual sensors may be provided to accept outputs of physical sensors as inputs in a model of a system that represents a product. The outputs of the virtual sensors are calculated from physical sensor outputs. In particular, the virtual sensors are calculated by exploiting information and analysis provided in a computer aided design (CAD) environment, including a CAD model and CADs simulation engine.
Claims20
In a computing device having a processor, a method, comprising:
- with a computer aided design (CAD) service, receiving an output of a physical sensor on a product, wherein said output is associated with at least one parameter in a CAD model of the product and wherein the CAD model has a virtual sensor that uses the output of the physical sensor to calculate an output;
- causing a simulation of the CAD model to be initiated with the output of the physical sensor as an input to the simulation;
- receiving results of the simulation, including a calculated value for the output of the virtual sensor;
- and
- reporting the output of the virtual sensor based on the results of the simulation.
In a computing device having a processor, a method, comprising:
- with the processor, defining a virtual sensor on a computer aided design (CAD) model of a product, said CAD model holding information regarding the product;
- receiving output from a physical sensor positioned to acquire physical information of a product that is in use, wherein the physical sensor senses a physical property;
- and
- with the processor, calculating an output for the virtual sensor based on some of the information held in the CAD model and the output of the physical sensor.
A non-transitory computer-readable storage medium storing instructions that when executed on a processor of a computing device cause the processor to:
- receive an output of a physical sensor on a product with a computer aided design (CAD) service, wherein said output is associated with at least one parameter in a CAD model of the product and wherein the CAD model has a virtual sensor that uses the output of the physical sensor to calculate an output;
- cause a simulation of the CAD model to be initiated with the output of the physical sensor as an input to the simulation;
- receive results of the simulation, including a calculated value for the output of the virtual sensor;
- and
- report the output of the virtual sensor based on the results of the simulation.
