Method, device and system for configuring power supply system

Abstract

The invention relates to a method, a device and a system for configuring a power supply system. The method comprises the following steps of distributing a total available power to each power supply apparatus according to an initialization distribution strategy; monitoring the variable attribute of the power supply system; when the change of the variable attribute is monitored, ordering all ports according to the priority level of each port on each power supply apparatus, sequentially accumulating the needed power of each port according to the sequence of the ports, respectively counting the needed power of each power supply apparatus, and redistributing the total available power to each power supply apparatus according to the needed power. The device comprises an initialization distribution module, a monitoring module, an ordering module and a power distribution module for realizing the method. The system comprises the configuration device for the power supply system as well as a power module and a power supply apparatus. In the invention, after all ports on each power supply apparatus are completely ordered, the total power of the power source is redistributed according to the needed power, thereby ensuring the power supply of the high priority port, realizing the distribution according to the needs and saving power.

Description

technical field [0001] The invention relates to power supply technology, in particular to a configuration method, device and system for a power supply system in remote power supply technology. Background technique [0002] The 802.3af standard approved by the Institute of Electrical and Electronics Engineers (hereinafter referred to as IEEE) in June 2003 clearly stipulates the power detection and control items in the remote system, which also clearly stipulates the Power over Ethernet ( Powerover Ethernet, hereinafter referred to as PoE) system related content. [0003] A PoE system generally includes a power supply end device (Power Sourcing Equipment, hereinafter referred to as PSE) and a power receiving end device (Power Device, hereinafter referred to as PD), and the PSE supplies power to the PD through an Ethernet cable. PD is the PSE load receiving power supply, that is, the client device of the PoE system, such as IP phone, network security camera, wireless local are...

AI Technical Summary

Problems solved by technology

Because each subsystem is independent, there may be a situation that a low power supply priority port in one subsystem can supply power, but a high power supply priority port in another subsystem cannot supply power, that is, the power supply priority of the port is at It cannot be reflected between different subsystems or different power supply modules
