The embodiment of the invention discloses a piece of central office equipment, a reverse power supply system and a method. The central office equipment comprises a current sharing module, an energy storage module and a power supply detection module. A PD interface module and a DC / DC module are sequentially connected between the PSE and the power supply port of the current sharing module. The current sharing module is configured to uniformly distribute the power supply power of the local terminal equipment to each PSE; The power supply detection module is used for real-timely monitoring the working state of each PD interface module and each DC / DC module, and outputting the working indication signal to the energy storage module when the local terminal equipment is detected to be in the single port power supply state or power-down state. The energy storage module is used for controlling the output voltage of the energy storage module to supply power to the equipment at the central officeequipment according to the operation indication signal. The embodiment of the invention solves the problem that the output voltage of the single port PSE is turned off due to the overcurrent or overload of the single port PSE when the existing reverse power supply system is switched to the single port power supply mode, thereby causing the single port PSE to be unable to carry out normal service.
Description
technical field [0001] The present invention relates to but not limited to the technical field of wireless communication, especially a central office device, a reverse power supply system and a method. Background technique [0002] Supplying power to the central office equipment through a network terminal (such as a user terminal) is called reverse power supply. A complete reverse power supply system includes one or more user-side power supply equipment (Power Sourcing Equipment, referred to as: PSE) and a local end powered device (Powered Device, referred to as: PD) (hereinafter referred to as the local end device) . [0003] figure 1 It is a schematic structural diagram of a reverse power supply system provided in the prior art. The reverse power supply system is usually applied in the scenario of multi-port reverse power supply, namely figure 1 The N PSEs in the network are connected to the N power supply ports of the central office equipment in one-to-one corresponde...
