Patent ID: 8862916

Claim:
A power control device, comprising: a power controller, comprising: a first signal transmission interface, connected to a second signal transmission interface of a host computer, for receiving a periphery power control flow data and a mode signal from the host computer, wherein the mode signal is either a working signal or a non-working signal; a first communication unit; a first micro-control unit electrically coupled to the first signal transmission interface and the first communication unit, for outputting a control signal according to the periphery power control flow data and the mode signal, for communicating with a second communication unit of a power socket through the first communication unit to wirelessly transmit the control signal to the power socket, wherein the first communication unit and the second communication unit are antennas, and the first communication unit is disposed in the power controller while the second communication unit is disposed in the power socket; and a first indication unit, used to display signal transmission quality of the first communication unit and/or types of the mode signal; wherein when the mode signal is the working mode signal, the control signal is a start powering signal, and when the mode signal is the non-working signal, the control signal is a stop powering signal, which is configured to stop the power socket from being powered after a predetermined time delay; and the power socket, comprising: the second communication unit, for wirelessly communicating with the first communication unit for receiving the control signal; a second micro-control unit, electrically coupled to the second communication unit; a power switching unit, electrically coupled to the second micro-control unit; a timing output unit; a full-time output unit, wherein the power switching unit is electrically coupled between an input power interface and the timing output unit, the second micro-control unit is further electrically coupled to the power switching unit, the timing output unit allows for insertion of the peripheral devices, and the second micro-control unit receiving the control signal through the second communication unit, the second micro-control unit controls operations of the power switching unit before controlling the timing output unit to output a first power from the input power interface, and wherein the timing output unit is configured to stop outputting the power to the peripheral devices associated with the host computer from the input power interface after the predetermined time delay; and a second indication unit, for outputting an indication signal in accordance to signal transmission quality of the second communication unit or a counting of a counter unit.
