1. A system for collecting a standby electricity-saving information of an electrical appliance, comprising:

  • a data transmission network;

    a power-saving information collection server, which is connected to the data transmission network;

    a server side network connection port, which is connected between the power-saving information collection server and the data transmission network;

    at least a user side network connection device, which is connected to the data transmission network;

    at least a device-standby power-saving controller, which comprises a control unit, a storage unit connected to the control unit, a current detection unit, a network connection port, a circuit switch, a driver unit that controls the circuit switch to open or close, the device-standby power-saving controller being connected via the network connection port to the control unit and the user side network connection device, the circuit switch and the current detection unit being connected between a power source and the electrical appliance that is arranged at the user side;

    wherein the electrical appliance is operated in one of an operation mode, a standby mode, and a shutdown mode, the control unit being operated so that after the electrical appliance is set in the standby mode for a predetermined period of time, the control unit controls, via the driver unit, the circuit switch to open; and

    wherein with the circuit switch being opened, the control unit detects a time interval of power interruption for the electrical appliance resuming the operation mode and calculates and generates a power-saving message based on the power interruption time interval and a standby current value, the power-saving message generated by the device-standby power-saving controllers being transmitted through the network connection port, the user side network connection device, the data transmission network, and the server side network connection port to the power-saving information collection server.
