Abstract

The present invention provides a PoE power supply receiving method and a PoE power supply receiving device, wherein the method includes the step of accessing a power source from the N network ports of the PoE power supply device using N PD interface circuitry, wherein N ā‰„ 2; detects each PD interface.The working status information of the circuit is performed according to the working state information to obtain an enable signal to control power-on, and the output power source of each PD interface circuit is accessed by the multi-phase switching power source, and the multi-phase switch is controlled according to the enable signal.The power supply status of the power supply; wherein the multi-phase switching power source has at least n mutually independent power input; outputting the output voltage of the multi-phase switching power supply to the system device.The technical solution of the present invention can increase the power supply power of the PoE device without affecting data transmission, and it is possible to effectively support the power supply reception security, and improve the operation stability of the system equipment.

Description

technical field [0001] The present invention relates to the technical field of power supply over Ethernet, in particular to a POE power receiving method and a POE power receiving device. Background technique [0002] POE (Power over Ethernet) Power over Ethernet technology refers to the transmission of data signals for some IP-based terminal equipment while the existing Ethernet Cat.5 cabling infrastructure does not make any changes. Technology for supplying DC power to such devices (system devices). The advantages of POE power supply are: 1. Simple installation, simple wiring, no need to arrange power lines, only need to arrange Ethernet cables to realize power supply to system equipment; 2. In some special network environments (such as elevated), no It is convenient to arrange the power cord / power adapter, and the power supply within 100M can be easily realized by using the Ethernet cable. [0003] At present, there are two specifications for POE power supply, IEEE802.3a...
