Intelligent POE power source supplying system and efficient POE power source managing method thereof

Abstract

An intelligent POE power source supplying system comprises a PSE device and a plurality of PD devices. The PSE device comprises a POE power module, a POE control unit, a micro-control unit, a power supplying pre-processing unit and a power supplying arbiter. The POE power module is connected with the power supplying pre-processing unit. The output end of the power supplying pre-processing unit is respectively connected with the input end of the POE control unit and the input end of the power supplying arbiter. The output end of the power supplying arbiter is connected with a main control unit which is connected with the POE control unit. The output end of the POE control unit is provided with a plurality of power supplying ports connected with the PD devices. According to the intelligent POE power source supplying system, the product cost is effectively reduced, one low-end POE chip is enough in the technical scheme, and it is enough that the chip has the basic detecting and power supplying functions. The power utilizing rate of the system is high, and when the system power supplying is not enough, the number of the power supplying ports of the system is maximal, and the power output is maximal.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to an intelligent POE power supply system and a high-efficiency POE power management method thereof. Background technique [0002] POE (Power on Ethernet, Power over Ethernet) refers to the transmission of data signals for some network terminal equipment without any changes to the existing Ethernet Category 5 twisted-pair cabling infrastructure. This type of equipment provides DC power supply technology. POE technology can guarantee the normal operation of the existing network while ensuring the safety of the existing structured wiring. A complete POE system includes two parts: power supply equipment (PSE, Power Sourcing Equipment) and power receiving equipment (PD, Power Device). . The PSE device is a device that supplies power to Ethernet client devices, and is also the manager of the entire POE Power over Ethernet process. The PD device is the PSE load that recei...

AI Technical Summary

Problems solved by technology

Each feature will increase the price of the chip by about 10-20%

[0005] 2) Low power utilization: The power utilization is mainly determined by two factors, the number of power supply ports and the output power

As a result, the following problems are caused: a. When the total power of low priority ports is lower than the power requirement of the access device, all low priority ports will be disconnected, and the access device cannot supply power, resulting in power supply disorder and power utilization. reduce

b. Among the low-priority ports, a port with high power consumption is not disconnected, but other ports with low power consumption are disconnected, which will also lead to a decrease in power utilization
