Patent US9691030

Issued 2017-06-27

Assisted Labeling Of Devices With Disaggregation

Electrical usage of devices in a building may be monitored to assist a user in labeling devices. In some implementations, a user may provide information about a first device, and this information may be used to obtain a plurality of mathematical models that each correspond to a device or a class of devices. The mathematical models may be used to process an electrical signal, and a score may be generated for each mathematical model. A mathematical model may be selected from the plurality of mathematical models using the scores, such as selecting a mathematical model with a highest score. The first device may be associated with the selected mathematical model.

3 Independent Claims

1. One or more non-transitory computer-readable media comprising computer executable instructions that, when executed, cause at least one processor to perform actions comprising: causing a prompt to be displayed to a user requesting that the user provide first information corresponding to a first device; receiving the first information from the user corresponding to the first device; obtaining a plurality of mathematical models using the first information, wherein each model of the plurality of mathematical models corresponds to a device or a class of devices; measuring an electrical signal from the building, wherein the electrical signal powers a plurality of devices; computing a plurality of features from the measured electrical signal; computing a plurality of scores using the plurality of mathematical models and the plurality of features, wherein (i) the plurality of mathematical models comprises a first mathematical model and (ii) the plurality of scores comprises a first score computed using the first model and the plurality of features; selecting the first mathematical model using the plurality of scores; and associating the first device with the first mathematical model.
8. A computer-implemented method for labeling devices in a building utilizing an electrical signal representative of the electrical usage of the devices, the method comprising: receiving first information from a user corresponding to a first device in the building; obtaining a plurality of mathematical models using the first information, wherein each model of the plurality of mathematical models corresponds to a device or a class of devices; computing a plurality of features from the electrical signal; computing a plurality of scores using the plurality of mathematical models and the plurality of features; selecting a first mathematical model from the plurality of mathematical models using the plurality of scores; and associating the first device with the first mathematical model.
15. A system for labeling devices in a building utilizing an electrical signal representative of the electrical usage of the devices, the system comprising: one or more computers comprising at least one processor and at least one memory, the one or more computers configured to: receive first information from a user corresponding to a first device in the building; obtain a plurality of mathematical models using the first information, wherein each model of the plurality of mathematical models corresponds to a device or a class of devices; compute a plurality of features from the electrical signal; compute a plurality of scores using the plurality of mathematical models and the plurality of features; select a first mathematical model from the plurality of mathematical models using the plurality of scores; and associate the first device with the first mathematical model.
