摘要： An apparatus and method for multi-point detection in a power source equipment (PSE) device is provided. During multi-point detection, a series of at least four currents is sequentially applied to a link port of the PSE device. Each current is applied during a different measurement interval. A voltage measurement sample is obtained for each of the measurement intervals. A difference in voltage between alternating voltage samples is determined and used by a detection module to determine whether a valid power device is coupled to the link port of the PSE.

摘要： Power over Ethernet (PoE) communication systems provide power and data communications over the same communications link, where a power source device (PSE) provides DC power (for example, 48 volts DC) to a powered device (PD). The DC power is transmitted simultaneously over the same communications medium with the high speed data from one node to the other node. The PSE typically includes a controller that controls the DC power provided to the PD at the second node of the communications link. The PSE controller measures the voltage, current, and temperature of the outgoing and incoming DC supply lines to characterize the power requirements of the PD. In addition, the PSE controller may detect and validate a compatible PD, determine a power classification signature for the validated PD, supply power to the PD, monitor the power, and reduce or remove the power from the PD when the power is no longer requested or required. The PSE controller also monitors for a Maintain Power Signature (MPS). The PSE controller removes power from the PD if the MPS condition is absent for longer than its related time limit. The MPS consists of two components: an AC MPS component and a DC MPS component. The PSE controller may optionally monitor the AC MPS component only, the DC MPS component only or both the AC and the DC MPS components.
