The invention provides a power supply transmission system for an Ethernet network. The power supply transmission system comprises a first PSE (Power Supply Equipment) control module, a second PSE control module, a first PD (Potential Difference) control module, a second PD control module, a first power supply loop, a second power supply loop and an adjusting module, wherein the adjusting module is connected with the first PD control module and the second PD control module respectively; the first PSE control module is used for supplying power to the first PD control module through the first power supply loop; the second PSE control module is used for supplying the power to the second PD control module through the second power supply loop; and the adjusting module is used for outputting voltage output by the first PD control module and voltage output by the second PD control module after being combined to electric equipment in an output matching process of the first PD control module and the second PD control module. The power supply transmission system provided by the embodiment of the invention can be used for supplying 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 powering some IP-based terminals (such as IP phones, wireless LAN access points, network cameras) without 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), wherein, PSE can include PSE control module and power supply equipment, PD equipment can include PD control module and power consumption equipment. PSE is a device that supplies power to Ethernet client devices, and is also the manager of the entire Ethernet power supply process. PD is the PSE load that receives power, that is, the client device of the PoE system. The power-consuming devices in the PD can be IP phones, ...
