System and device for monitoring at least one household electric user, in particular a household appliance
First Claim
1. A monitoring or control device interposed between an electric power source and a plurality of household electric users, the device comprising:
- means for supplying power to said plurality of household electric users over respective power supply lines;
a plurality of metering means for measuring at least one of electric current and electric power absorbed instant by instant by each of said household electric users, said electric current and said electric power absorbed being representative of a modulation of electric power by which each of said household electric users transmits data to said device;
a plurality of modulation means for implementing a modulation of electric power supplied to each of said household electric users, to communicate data to each of said household electric users through their respective power supply lines;
a plurality of decoding means connected to receive measurements from said metering means, for decoding the modulation of electric power absorbed by each of said household electric users; and
a single connecting means for connecting to a network and communicating over the network using a protocol and communication media, said connecting means providing data communicated from the network to at least one of said modulation means for communication to at least one of said household electric users.

Abstract
A system that monitors at least a household electric user, in particular a household appliance, includes a monitoring device that is connected between a source of electric energy and the electric user, the monitoring device including a metering means for detecting one or more electric quantities being associated with the operation of said user, and further including a control means that is programmed for (i) comparing the electric quantity or quantities being measured through the metering means with reference values of said electric quantity or quantities which are stored within the control means; (ii) generating, in function of the comparison, information being representative of the current operating status or phase of operation of the electric user; and (iii) allowing for the reading or transmission of the information to the outside of said device. The monitoring device also including a communication means, for realizing a transmission and/or reception of data or information on the electric supply line which connects the user to the device, by means of a modulation of electric power between the user and the device and/or vice-versa.

15. A monitoring and control device including
outlets for connecting a plurality of household electric users to power over respective power supply lines; -
a plurality of metering means, one per power supply line, for measuring over the power supply lines at least one of electric current and electric power absorbed instant by instant by respective household electric users, said electric current and said electric power absorbed by a given household electric user being representative of a modulation of electric power by which said given household electric user transmits data to said device; a plurality of modulation means, one per power supply line, for implementing a modulation of electric power supplied to respective household electric users, to communicate data to respective household electric users through their respective power supply lines; a plurality of decoding means connected to receive measurements from said plurality of metering means, for decoding the modulation of electric power absorbed by said respective household electric users; and a single connecting means for connecting to a network and communicating over the network using a protocol and communication media, said connecting means providing data communicated from the network to said plurality of modulation means for communication to said respective household electric users data communicated from the network. - View Dependent Claims (16, 17, 18, 19, 20, 21)
