Abstract
An asset class type of a new asset is predicted or determined based upon an evaluation of time series data from the new asset. A predicted asset type is used to identify sensors of the new asset to use for data collection. Using the readings of selected sensors from the new asset, states of the new asset are obtained. The duration at least one of these states of the new asset is determined. This information can be subsequently used to optimize the performance of the new asset.
Claims14
A method, the method comprising:
- storing a model in a memory, the model describing and predicting behavior of a new machine that is to be added to a group of currently operating machines;
- sensing first time series data at the new machine with a plurality of sensors;
- determining a type of the new machine based at least in part upon a comparison of the model with the first time series data;
- based upon the determined type, selecting one or more of the plurality of sensors to obtain additional data, the selected ones of the plurality of sensors sensing second time series data from the new machine;
- determining one or more of an event, a state, or an event duration at the new machine based upon an analysis of the second time series data;
- and
- responsively determining an action that improves performance of the new machine based upon an evaluation of one or more of the determined event, state, or event duration.

A system, the system comprising:
- a network;
- a currently-operating machine that is coupled to the network;
- a new machine that is to be added with the currently operating machine, the new machine having a plurality of sensors that sense first time series data at the new machine;
- a control circuit including a memory that stores the model that describes and predicts behavior of the new machine, the control circuit being coupled to the network, the control circuit being configured to determine a type of the new machine based at least in part upon a comparison of the model with the first time series data, the control circuit further configured to, based upon the determined type, select one or more of the plurality of sensors to obtain additional data, the selected ones of the plurality of sensors sensing second time series data from the new machine, the control circuit being further configured to determine one or more of an event, a state, or an event duration at the new machine based upon an analysis of the second time series data;
- and responsively determine an action that improves performance of the new machine based upon an evaluation of one or more of the determined event, state, or event duration.
