Description

technical field [0001] The invention belongs to the technical field of power management, in particular to a remote power supply control device. Background technique [0002] The remote power supply system (that is, POE power supply) refers to the remote power supply of external PD (Powered Device, powered device) by PSE (Power Sourcing Equipment, power supply equipment) through PI (Power Interface, power supply interface), using twisted pair wires. [0003] At present, the standard PoE power supply itself has a limited transmission distance, and because it does not have the relay function to extend the PoE power transmission distance, it cannot perform power management. At the same time, the use of current-limiting chips in the power supply of smart meters through the remote power supply system has the disadvantage of causing all functional modules to be down at the same time or the use of each functional module is limited. Contents of the invention [0004] The technical...
