Technical field
The invention belongs to communication technique fields, specifically, more particularly to a kind of base for base station power power supply management Power supply of standing differentiates processing method and its device.
Background technique
Currently, the power supply mode of base station usually there are 3 kinds, it is respectively as follows: mains-supplied, oil machine power supply and storage battery power supply. During the normal operation of base station, power supply is mains-supplied;After grid power blackout, base station is first carried out by battery temporary When power, and by base station monitoring-controlling system issue power-off warning information notify to give base station maintenance personnel, base station maintenance personnel are being connected to After powering off warning information, corresponding base station location starting oil machine is reached to be powered from hydro power generation to base station, until power grid is extensive After multiple power supply, base station switchback mains-supplied again at this time.
