The embodiments of the invention provide a receiving end device and a receiving method, aiming at addressing the technical problem of insufficient power of receiving end devices that have high power consumption. The receiving end device includes: at least two interface circuits, the input end of each interface circuit of the at least two interface circuits being in connection with a network interface of a power supply end device for receiving the output power supply which is output by the power supply end device, wherein each interface circuit includes a positive power supply loop, a negative power supply loop, and a load module; an isolation module which is connected to the load module of each interface circuit and is intended for isolating the output power supply which is received by the input end of each interface circuit from a unipotential of the working voltage inside the receiving end device; and a power supply converging module which is connected to each interface circuit, and is intended for combining the power supplies of the power supply loops of the at least two interface circuits which are isolated, and acquiring and outputting a combiner power supply after the combination, wherein the current in the combiner power supply is the sum of the currents of the at least two interface circuits.
Description
technical field [0001] The invention relates to the field of electronic technology, in particular to a power receiving terminal device and a power receiving method. Background technique [0002] The Power Over Ethernet (POE) system refers to powering some IP-based power receiving devices (such as IP telephones, wireless Access point (Wireless Access Point, AP), network camera, etc.) while transmitting data signals, can also provide DC power supply for these powered end devices. [0003] The existing POE mainly includes two parts: power sourcing equipment (Power Sourcing Equipment, PSE) and power receiving equipment (Power Device, PD). Among them, the PSE is a device that supplies power to the Ethernet power receiving end device, and is also the manager of the entire POE power supply process. The PD is the PSE load receiving power, that is, the network device in the POE system. At present, when a PD device is connected to the network, the PSE device can immediately detect ...
