description The utility model relates to an embedded system which comprises a main chip, a network interface controller, a micro control unit, a switch and a power supply. When the system is not working, the main chip produces a sleep signal. The network interface controller is used for receiving a wakeup packet from a network and sends a wakeup signal. The micro control unit sends a connection signal after receiving the wakeup signal from the main chip, and sends a disconnection signal after receiving the sleep signal from the network interface controller. The free end of the switch is connected with the main chip, and the control end thereof is connected with the micro control unit, and is used for receiving the connection signal so that the switch is connected, and receiving the disconnection signal so that the switch is disconnected. The power supply is connected with the network interface controller and the micro control unit to supply powder and is connected with the public end of the switch for supplying power to
