Embodiment Construction

[0049] 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 conditions of n electrical devices 101_1 to 101_n. Each electrical device 101_1 to 101_n is connected to a power socket 103_1 to 103_n of the power supply network 110 by a corresponding power cable 102_1 to 102_n. It should be realized 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 corresponding 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.

[0050] Each power cable 102_1 to 102_n is equipped with a respective plug 104_1 to 104_n for connecting the respective power cable to a respective power socket 103_1 to 103 — n for connection to the power ...

Abstract

An electrical activity sensor device for monitoring the electrical status of an electrical device, the device comprising: a power cable for supplying power to an electrical device from a power supply network, the power cable being fitted with an in-line switch enabling the electrical device to be switched between electrical power states; wherein: the antenna element is operable to transfer the identification data to the power cable; and the power cable is operable to operate as an antenna when the electrical device is switched on to transmit identification data wirelessly from a sensor device attached to the cable to a reader device.

Description

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