Abstract

The invention discloses POE equipment, which comprises a detection circuit and a voltage inversion circuit, wherein the input end of the detection circuit is connected with the input end of POE equipment, the control end of the voltage inversion circuit is connected with the output end of the detection circuit, and the first output end and the second output end of the voltage inversion circuit areboth connected with power receiving equipment; the detection circuit is used for detecting the input voltage of the input end of POE equipment, and outputting a power-down control signal when the input voltage is smaller than a preset power-down threshold value; the voltage inversion circuit comprises a plurality of switch tubes and is used for receiving the power-down control signal and controlling the working states of the switch tubes according to the power-down control signal so as to enable the output voltage of the first output end and the output voltage of the second output end to beinverted. The embodiment of the invention further discloses a POE system, by adopting the embodiment of the invention, time expenditure brought by participation of the CPU at the power supply end canbe effectively reduced, so that the power receiving equipment after power failure has more sufficient time to process data.

Description

technical field [0001] The present invention relates to the technical field of power supply, in particular to a POE power supply device and system. Background technique [0002] Dying gasp refers to the signal that when the system power fails and the device detects that the power supply cannot meet the normal use, it sends a power-off message to the peer device. The dying gasp in the switch field will send dying gasp messages on all ports after detecting that the power is about to be lost. The POE power supply equipment transmits energy through the network cable, and the powered equipment does not need to be connected to the mains power supply, and obtains energy from the network cable, which greatly reduces the cost of network laying and has been widely used. [0003] In the traditional Dying gasp design, when the POE power supply is reduced to a certain extent, the system power supply of the POE power supply equipment will be reduced, and there is a problem that the abnor...
