Abstract

The present invention provides a power over Ethernet transmission system. The system comprises a first PSE control module, a second PSE control module, a first PD control module, a second PD control module, a first power supply circuit, a second power supply circuit, and an adjusting module respectively connected to the first PD control module and the second PD control module. The first PSE control module is used to supply power to the first PD control module through the first power supply circuit. The second PSE control module is used to supply power to the second PD control module through the second power supply circuit. The adjusting module is used to, when the output of the first PD control module matches with that of the second PD control module, combine an output voltage of the first PD control module with that of the second PD control module and output the combined voltage to an electrical apparatus. The embodiment of the present invention can provide large-power transmission.

Description

technical field [0001] The invention relates to power supply technology, in particular to an Ethernet power supply transmission system. Background technique [0002] Power over Ethernet (PoE) refers to power supply for some IP-based terminals (such as IP telephones, wireless LAN access points, and network cameras) without making any changes to the existing Ethernet cabling infrastructure. While transmitting data signals, it can also provide DC power supply technology for such devices. [0003] A complete PoE system includes Power Sourcing Equipment (PSE) and Powered Device (PD), where the PSE can include a PSE control module and a power supply device, and the PD device can include a PD control module and a power supply. equipment. PSE is a device that supplies power to Ethernet client devices, and is also the manager of the entire power over Ethernet process. PD is the PSE load that receives power, that is, the client device of the PoE system. The power devices in PD can b...
