Abstract
A power control system includes an electronic device including a relay connected to a mains supply, a control circuit connected to the relay, and a receptive circuit connected to the control circuit, and a remote control device including a transmission circuit for transmitting a triggering signal to the receptive circuit. Upon receipt of the triggering signal from the receptive circuit, the control circuit generates, based on the triggering signal, a driving voltage sufficient for switching the relay from an off state to an on state to permit supply of electricity from the mains supply to the electronic device for driving operation thereof.
Claims15
A power control system, comprising:
- an electronic device including a relay that is adapted to be electrically connected to a mains supply, a control circuit that is electrically connected to said relay, and a receptive circuit that is electrically connected to said control circuit, wherein said control circuit is capable of generating a driving voltage that is sufficient for switching said relay from an off state to an on state, such that said relay permits supply of electricity from the mains supply to said electronic device for driving operation thereof;
- and
- a remote control device including a transmission circuit that is capable of establishing a connection with said receptive circuit of said electronic device, said remote control device being operable to transmit via said transmission circuit a triggering signal to said receptive circuit;
- wherein upon receipt of the triggering signal via said receptive circuit, said control circuit generates the driving voltage based on the triggering signal.
A power control system, comprising:
- an electronic device including a relay that is adapted to be electrically connected to a mains supply, a control circuit that is electrically connected to said relay, and a receptive circuit that is electrically connected to said control circuit;
- and
- a remote control device including a transmission circuit that is capable of establishing a connection with said receptive circuit, said remote control device being operable to transmit via said transmission circuit an electrical signal to said receptive circuit;
- wherein upon receipt of the electrical signal from said receptive circuit, said control circuit generates a driving voltage based on the electrical signal to control said relay to switch between off and on states so as to switch said electronic device between a power interruption mode, where said electronic device is electrically isolated from the mains supply by said relay, and an operation mode, where said electronic device receives electricity from the mains supply through said relay.
