Problems solved by technology

If in this case, the Power Bank cannot be switched in time, on the one hand, it will fail to supply power in time when it should be powered on, resulting in a delay in powering on the PD device; on the other hand, it will not be powered off in time when it should be powered off, resulting in The device itself is burned out

Embodiment Construction

[0023] Taking the PSE device in the multi-power PSE system as an example which has two power supply slots and can support two types of power supplies, the embodiments of the present invention will be described with reference to the accompanying drawings.

[0024] figure 1 shows a mainboard of a PSE device, the following is figure 1 What is shown is taken as an example to describe the specific implementation process of the embodiment of the present invention.

[0025] Such as figure 1 As shown in the figure, there are two pluggable power supply slots on the motherboard, denoted by power supply slot 0 and power supply slot 1 respectively. Each power supply slot can support type A and type B power supplies. Each power supply slot can be plugged with any type of power supply of type A and type B, and of course no power supply can be plugged in.

[0026] Each power slot is the same as the interface module of the motherboard. The status of the power slot can be indicated by the...

Abstract

The invention discloses a power over ethernet (PoE) power gating switchover method and device. The method is applied to power sourcing equipment (PSE) with a complex programmable logic device (CPLD) and a central processing unit (CPU) and includes that corresponding power bank (PB) conservative values are determined according to power good (PG) information and PB register values before state change and PG information after state change after the CPLD detects power slot position state changes, and corresponding PB signals are output according to determined PB conservative values; and the CPLD triggers the CPU to inquire power of a power source on a current power slot position and determine corresponding PB register values according to query results and outputs corresponding PB signals according to the PB register values determined by the CPU. By means of the method and the device, PoE power gating fast switch can be achieved under the condition of switching of power on multi-power-source PSE.

Description

technical field [0001] The present invention relates to the communication field, in particular to a PoE power threshold switching method and equipment. Background technique [0002] PoE (Power over Ethernet, Power over Ethernet) refers to the power supply for some IP-based terminals (such as IP phones, wireless LAN access points) without any changes to the existing Ethernet Cat.5 cabling infrastructure. AP, network camera, etc.) while transmitting data signals, it can also provide DC power supply technology for such devices. PoE technology can guarantee the normal operation of the existing network while ensuring the safety of the existing structured wiring, and minimize the cost. [0003] A complete PoE system includes two parts: Power Sourcing Equipment (PSE) and Powered Device (PD). The PSE device is a device that supplies power to Ethernet client devices, and is also the manager of the entire PoE system's power-over-Ethernet process; the PD device is the load of the PSE...
