Problems solved by technology

However, in practical applications, once the carrier frequency unit and power amplifier unit in the base station are all turned off, mobile users in the cell covered by the base station will not be able to access the base station, resulting in personal mobile users in the cell communication service interruption

Embodiment Construction

[0022] The method of the present invention for prolonging the power supply time of the storage battery, which is used for power supply of the base station, is characterized in that at least three threshold voltages are set according to the discharge characteristics of the storage battery, and one of the threshold voltages is the cut-off voltage V d , and other threshold voltages are greater than the cut-off voltage V d ;Detect the discharge voltage V of the battery output f , and compared with each threshold voltage, it is judged that the discharge capacity of the storage battery is reduced, and the total power consumption is adjusted in stages. When V f >V d Keep the important load power supply of the base station. In this way, the total power consumption is reduced step by step, instead of reducing the total power consumption according to a threshold voltage as in the prior art, which not only prolongs the battery power supply time but also prolongs the service time of mo...

Abstract

The invention discloses a method for prolonging the accumulator supply feed time. The accumulator is used in base station supply feed. It arranges at least three valve value voltages by the accumulator discharging character, wherein one of the three valve value voltage is a blackout voltage Vd, the other valve value voltages are greater than the blackout voltage Vd; it tests the discharging voltage of the accumulator Vf and compares it with each valve value voltage to quote discharging content of the accumulator and adjust the total power consumption.

Description

technical field [0001] The invention relates to a communication device powered by a storage battery, in particular to a method for prolonging the power supply time of the storage battery. Background technique [0002] At present, the outdoor macro base stations in the communication system are generally equipped with batteries, so that after the AC power supply is cut off, the batteries continue to supply power to the macro base stations to ensure the normal communication of the communication system. [0003] see figure 1 , the existing base station network adopts a chain communication mode, and a base station controller controls multiple base stations. Wherein, the base station controller, the base station 1, the base station 2, the base station N-1, and the base station N are serially connected in series. Base station 1 directly communicates with the base station controller; base station 2 connects with base station 1 and communicates with the base station controller thro...
