Abstract
A powered device (PD) detection device is configured to identify a type of power sourcing equipment. The PD detection device includes a detection circuit and a processing circuit, and the detection circuit is connected to the processing circuit. The detection circuit is configured to: receive hierarchical waveform information sent by the power sourcing equipment, and generate a corresponding first-type signal or a corresponding second-type signal based on the hierarchical waveform information, and is further configured to send the first-type signal or the second-type signal to the processing circuit, where the first-type signal corresponds to first-type power sourcing equipment, and the first-type power sourcing equipment includes at least one of non-standard power sourcing equipment and a direct current adapter. The processing circuit is configured to: receive the first-type signal or the second-type signal, and determine the type of the power sourcing equipment based on the first-type signal or the second-type signal.
