Embodiment Construction

[0098] The making and using of the presently preferred embodiments are discussed in detail below. It should be appreciated, however, that the present invention provides many applicable inventive concepts that can be embodied in a wide variety of specific contexts. The specific embodiments discussed are merely illustrative of specific ways to make and use the invention, and do not limit the scope of the invention. Furthermore, the same reference signs refer to the same technical features, if not stated otherwise. To the extent that "may" is used in this application, it means the possibility of doing so as well as the actual technical implementation.

[0099] figure 1 A flowchart showing method steps is presented. After starting (step 100 ), an initial switch-off condition for the current is detected in step 101 . An initial turn-off condition is detected in a state where current is turned on. Detection of the initial shut-off condition may be due to receipt of a message on...

Abstract

The invention relates to a method for switching on and off an electric current, the method comprising: detecting a verification condition (103); switching on a current (104) in response to the detected verification condition; after switching on said current via a communication network ( NW) establishing communication (105); detecting a shutdown condition via the established communication (106); and in response to the detected shutdown condition, shutting off the current flow (107). Additionally, devices and systems for controlling switching on and off current are presented.

Description

technical field [0001] The present invention relates to a method for switching on and off an electric current, as well as a device and a system for controlling the switching on and off of an electric current. Background technique [0002] Electromechanical meters currently installed for metering electrical energy consumption in, for example, homes and buildings do not provide the ability to remotely control the delivery of electrical power to said homes and buildings. In particular, these meters do not support remote cut and reconnect, ie, to remotely turn off and on the electrical current used for the electrical power delivery of the homes and buildings. Smart metering equipment implements new functionality for energy utilities that allows remote delivery shutoff, for example in the event of a delivery contract expiring or a customer failing to pay, or in the event of an ordinary disaster situation such as a fire, gas or water main break use. If the condition for delivery...
