FIELD: computer engineering.
SUBSTANCE: group of inventions can be used for determining of power consumption. Device comprises data obtaining module configured to receive data representing mixed signal of two or more sequential in time signals; state estimation module configured to parameter estimation of serial in time simulating signal, with factorial hidden Markov model (FHMM); at that, state estimation module is configured to parameter estimation with certain limitation by calculation of data variation, representing mixed signal of two or more time sequence signals; and using calculated variation as a FHMM parameter.
EFFECT: high accuracy of calculation of power consumption by each electric household appliance.
