Abstract

An apparatus and method for power management includes a first power supply module for obtaining power according to Power over Ethernet (PoE) technology and transmitting the power into a first power supply; a second power supply module providing a second power supply; a power detecting module outputting a first power voltage value corresponding to the first power supply; a power switching module receiving and outputting the first power supply, and outputting the second power supply when a switching signal is received; a mode determination module determining auto switching mode or manual switching mode and thereby generating an auto switching mode signal or manual switching mode signal; a control module transmitting a notification message when the first voltage value fails to meet a predetermined voltage during manual switching mode, and transmitting the switching signal when the first voltage fails to meet the predetermined voltage during auto switching mode.

Description

technical field [0001] The present invention relates to a power management method and a power management device, and more particularly, to a power management method and a power management device for a wireless access device. Background technique [0002] Due to the popularity of handheld devices, the demand for wireless Internet access has greatly increased. Therefore, the deployment of wireless base stations has become an important task. Due to the maturity of Power over Ethernet (Power over Ethernet) technology, wireless base stations that need to be deployed outdoors or at high places can obtain the power required by the wireless base station through the Ethernet cable and improve the deployment location of the wireless base station. power supply constraints, and the work cost of additional power wiring. [0003] However, once the power source required to provide the wireless base station is abnormal, such as power failure or unstable voltage, the wireless base station w...
