Embodiment Construction

[0059] The present invention will be further described below with reference to the drawings and specific embodiments, but it is not a limitation of the present invention.

[0060] For the POE system, the PSE equipment and PD equipment mainly follow the IEEE802.3at / af protocol to realize the function of circuit power supply.

[0061] Such as figure 1 As shown, in a preferred embodiment of the present invention, a PD device support system is included in a PD device. The PD device support system includes an input terminal 1 and an output terminal 2. The input terminal 1 is connected to a PSE device , For the PSE device to send pulses to the PD device support system; the aforementioned output terminal 2 is connected to the load of the PD device, so as to supply power to the load of the PD device.

[0062] In a preferred embodiment of the present invention, further, the aforementioned input terminal 1 includes a non-inverting input terminal 111 and an inverting input terminal 112, and the...

Abstract

The invention discloses a support system for a PD device and belongs to the technical field of POE systems. The support system for the PD device includes input ends, output ends, a detection module, a classification module and an electrifying module, wherein the input ends are connected with a PSE device and the output ends are connected with a load of the PD device; the detection module forms detection current between the input ends so that the PSE device can judge whether the PD device needs to the powered; the classification module forms classification current between the input ends so that the PSE device can judge the classification state of the PD device; and the electrifying module switches on the input ends and the output ends so that the PSE device can supply power to the PD device. The beneficial effects of the technical scheme are that switching of protocol content at different voltage phases is realized; and parameters can be changed to adapt to different systems.

Description

Technical field [0001] The present invention relates to the technical field of POE systems, in particular to a PD equipment support system and PD equipment. Background technique [0002] The POE system (Power Over Ethernet, Power Over Ethernet system) is a kind of infrastructure that relies on the existing Ethernet Cat.5 cabling infrastructure, and without any changes, is used for some IP-based terminals (such as IP telephones, wireless LAN access points (APs, network cameras, etc.) transmit data signals while also providing DC power supply technology for such devices. [0003] The POE system in the prior art includes PSE equipment (Power Sourcing Equipment) and PD equipment (Powered Device). The PSE device is a device that supplies power to the Ethernet client device, and the PD device is a PSE load that accepts power, that is, the client device of the POE system. [0004] The existing POE technology can ensure the normal operation of the existing network while ensuring the safety...
