Embodiment Construction

[0062] In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0063] Embodiments of the present invention provide a PoE-based power supply method and PSE, which are used to solve the problem that in the prior art, when the output voltage of the PSE is fixed, the line voltage drop of the network cable between the PSE and the PD is too large, causing the PD to receive The voltage of the PD cannot meet the requirements, which affects the normal operation of the PD. Wherein, the method and the control...

Abstract

The present invention discloses a PoE-based power supply method and PSE. The method includes: after the PSE supplies power to the PD, the PSE determines the line voltage drop of the network cable between the PSE and the PD, and when the line of the network cable When the voltage drop is greater than the line voltage drop threshold, the PSE sends a first Ethernet packet to the PD, so that the PD reduces load power consumption according to the instruction contained in the first Ethernet packet information, reduce its own load, ensure that the voltage received by the PD can meet the power demand of its own load, and then ensure that the PD can work normally.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a PoE-based power supply method and a PSE. Background technique [0002] Power over Ethernet (PoE for short) technology refers to powering terminals through Ethernet, which can effectively solve the problem of Internet Protocol (Internet Protocol, IP) phones, portable device chargers, credit card machines, cameras, and data collectors. Wait for the power supply problem of the terminal. For these terminals, it is no longer necessary to consider the wiring of the power supply system, and the power supply to the equipment can be realized while connecting to the network. The PoE system includes a Power Sourcing Equipment (PSE for short) and a Powered Device (PD for short), and the PSE is used to supply power to the PD. [0003] With the development of PoE technology and the improvement of standards, there are more and more types of devices that support remote power supply, an...
