Abstract

The invention discloses a method and system for supplying power through a PoE power supply system. The method comprises the steps: performing power-on initialization on PSE power supply equipment in the PoE power supply system; detecting whether PD power receiving equipment meeting a preset standard is accessed or not by the PSE power supply equipment after power-on initialization through a detection circuit; when the PSE power supply equipment detects that PD power receiving equipment meeting a preset standard is accessed, determining the power supply power of the PD power receiving equipmentthrough a grading circuit; and supplying power to the PD power receiving equipment through the PSE power supply equipment according to the determined power supply power.

Description

technical field [0001] The present invention relates to the technical field of network power supply, and more specifically, to a method and system for supplying power through a PoE power supply system. Background technique [0002] With the rapid development of network communication technology, PoE (Power over Ethernet, Ethernet) power supply mode has gradually been widely used in network terminals. PoE power supply can not only provide communication signals for network terminals, but also provide DC power supply to maintain the normal communication function of the network terminal; and in the PoE power supply mode, the transmission medium of the communication signal is low, and the scope of application is wide, and it can realize the communication interconnection between different types of network terminals, which greatly reduces the distance between network terminals. Therefore, in the current Ethernet communication system, PoE power supply has become the most important po...
