Wireless power supply control system and control method

The invention discloses a power supply control system and control method. The power supply control system is used for controlling the opening or closing of computer nodes in a computer cluster system and comprises a control terminal and a plurality of power supply control nodes connected by a wireless grid network, wherein the control terminal is suitable for acquiring route information and transmits a control signal to the power supply control nodes in a wireless way; the control signal carries an active address, a destination address, route information and information for the computer nodes to be controlled; the power supply control nodes are connected between the control terminal and the computer nodes, is suitable for receiving and analyzing the control signal and controlling the opening or closing of the corresponding computer nodes on the basis of the information for the computer nodes to be controlled; and when the power supply control nodes are the power supply control nodes pointed by the destination address, the power supply control nodes forward a control signal to the wireless grid network on the basis of the analyzed route information. The power supply control system has the advantages of strong extensibility and high safety.
