1. A powered device (PD) detection device, comprising:
a detection circuit; and
a processing circuit, and the detection circuit is connected to the processing circuit;
wherein the detection circuit is configured to: receive hierarchical waveform information from power sourcing equipment, and generate a corresponding first-type signal or a corresponding second-type signal based on the hierarchical waveform information, wherein the first-type signal corresponds to first-type power sourcing equipment, the second-type signal corresponds to second-type power sourcing equipment, the first-type power sourcing equipment comprises non-standard power sourcing equipment or an adapter, and the second-type power sourcing equipment comprises AF power sourcing equipment, AT power sourcing equipment, or BT power sourcing equipment; and
wherein the processing circuit is configured to: determine, based on the first-type signal, that the power sourcing equipment is the first-type power sourcing equipment, or determine, based on the second-type signal, that the power sourcing equipment is the second-type power sourcing equipment.
