Power supply management method, device and system

Abstract

The invention discloses a power supply management method, equipment and system. The method includes: the power supply device receives a power-on request from a first-level power receiving device, and the power-on request includes the port identification of the second-level power supply port whose detection result is valid in the first-level power receiving device; the power supply device According to the power-on request and the output power of the power supply equipment, determine the secondary power supply port in the first-level power receiving equipment that is allowed to be powered on, and send a power-on instruction to the first-level power receiving equipment, the The power-on instruction includes the port identifier of the secondary power supply port that is allowed to be powered on in the primary powered device, and is used to instruct the primary powered device to power on the secondary power supply port that is allowed to be powered on. In the power supply management method, the power supply equipment takes the first-level power receiving equipment and the second-level power receiving equipment connected to the first-level power receiving equipment as a whole, and performs power supply control and power management in a unified manner, which can improve the efficiency of power supply management, and Reduce overhead for primary powered equipment.

Description

technical field [0001] The present invention relates to the communication field, in particular to a power supply management method, device and system. Background technique [0002] Mobile terminals, such as smart phones and laptops, can access the Internet through a wireless local area network (WLAN). In some scenarios (for example, student dormitories, hospital wards, hotels, etc.), if only deploying access points (English: access point, AP) in public areas will result in poor indoor signal quality. And if the number of deployed APs is increased, the complexity of device management will be increased. [0003] A distributed WLAN network includes central APs and distributed APs. A central AP is connected to multiple distributed APs. Distributed WLAN networking can provide wider network coverage and simplify device management and configuration. [0004] Such as figure 1 As shown in FIG. 2 , it is a traditional architecture in which Power over Ethernet (PoE) technology is ...

Problems solved by technology

In this way, not only the Ethernet switch needs to perform power management and distribution, but the central AP also needs to perform power distribution and management for each distributed AP, which is not conducive to the power distribution and management of the entire distributed WLAN, and also increases the overhead of the central AP.
