Embodiment Construction

[0047] figure 1 is a schematic block diagram of an electrical activity monitoring system in which one or more embodiments of the present invention may be implemented. The electrical activity monitoring system 100 monitors changes in electrical states of n electrical devices 101_1 to 101_n. Each electrical device 101_1 to 101_n is connected to a power socket 103_n to 103_n of the electrical monitoring power supply network 110 via a respective power cable 102_1 to 102_n. It should be understood that although the figure 1 In the illustrated embodiment of the present invention, each electrical device 101_1 to 101_n is connected to a respective power outlet 103_1 to 103_n, but in other embodiments of the invention, multiple electrical devices may be connected to the same power outlet 103_x. Each power cable 102_1 to 102_n is equipped with a respective RFID sensor unit 200_1 to 200_n. The electrical activity monitoring system 100 also includes an electrical activity monitoring de...

Abstract

An electrical activity monitoring device based on an RFID sensor device attachable to a power cable of an electrical device for monitoring the electrical state of said electrical device. The device includes an antenna element that performs dual functions: magnetically couples with electrical pulses generated in the power cable in response to changes in the electrical power state of the electrical device, and wirelessly transmits data to an RFID reader. There is also provided an electrical activity monitoring device for monitoring the electrical status of at least one electrical device connected to a power supply network via respective power cables equipped with RFID sensor devices. The electrical activity monitoring device includes an RFID reader for communicating with the RFID sensor device.

Description

technical field [0001] The present invention relates to an electrical activity sensor device for detecting electrical activity of an electrical device connected to a power supply network, in particular a change in electrical power state. The invention also relates to an electrical activity monitoring device for monitoring electrical activity of one or more electrical devices. The electrical activity sensor device is based on a radio frequency identification device (RFID). Background technique [0002] Monitoring electrical activity of electrical devices finds many useful applications in fields such as energy consumption, building user activity profiles and in safety or security monitoring systems. For example, in a domestic environment, knowledge of the activity of electrical appliances such as washing machines, lighting, cookers, toasters, or coffee makers can provide useful information about household habits and user activities, enabling profiles to be built.
