Power control device

Abstract

A power control device is disclosed for managing the power supply of a terminal device having a communication interface for connecting to a remote server containing a timing unit. The device includes a power cord adapted to be connected to the terminal device, a relay connected to the power cord and having a control terminal, and a circuit switching element connected to the relay. The circuit switching element includes a network interface associated with the remote server and an output interface connected to the control terminal. The network interface provides a power-off signal input state, corresponding to a first time parameter associated with the timing unit, a subsequent second time parameter, and a connection state of the communication interface under the second time parameter. The output interface provides a power-off voltage level corresponding to this state, and the relay is controlled by this level to disconnect the power cord.
