Problems solved by technology
[0003] In order to realize that the power-taking equipment that does not meet the PoE standard takes power from the PoE system, the existing technology usually uses the PD device near the power-taking device to supply power to the power-taking device, that is, the nearby PD device first takes power from the PoE system. Then use itself as a power source to supply power to the power-taking device, but this method requires the PD device that supplies power to support the power expansion function. When the PD device near the power-taking device does not support the power expansion function, it cannot supply power to the power-taking device. Therefore, The applicability of this method is poor

The invention discloses a device for taking power from a PoE system and power taking equipment. The device comprises a power taking module and a power taking control module, the power taking end of the power taking module is connected between the output end of the PSE and the input end of the PD; the input end of the power taking control module is connected with the output end of the power taking module, the output end of the power taking control module is connected with the grounding end of the PSE equipment, the detection end of the power taking control module is connected with the output end of the PD equipment, and the power supply end of the power taking control module is connected with the power receiving end of the power taking equipment; the power taking control module is configured to output the voltage output by the PSE device to the power taking device when it is detected that both the PSE device and the PD device meet the preset power taking condition. According to the invention, electricity can be taken from the PoE system, the limitation that electricity can be supplied to electricity taking equipment which does not accord with the PoE standard only through nearby PD equipment supporting a power supply expansion function is not needed, and the method has higher applicability.
Description
technical field [0001] The present invention relates to the technical field of PoE, and in particular, to a device for taking electricity from a PoE system and a device for taking electricity. Background technique [0002] The full name of PoE is Power Over Ethernet, which refers to the power supply through the Ethernet network cable. Relying on the existing Ethernet wiring foundation, the power supply equipment can not only transmit data to the terminal equipment, but also provide DC power supply technology for the terminal equipment. PoE technology is widely used in Ethernet devices through the convenience of not requiring separate power cables. A PoE system in the prior art includes two parts: a PSE device (Power Sourcing Equipment, a device that supplies power to an Ethernet terminal device) and a PD device (Power Device, a terminal device that receives power). [0003] In order to realize that a power taking device that does not comply with the PoE standard can take po...
