The year of 2020 is the first year of 5G , the communications industry is undergoing vigorous development,major operators and tower groups are deploying a new generation of communications base stations. The power consumption of base stations continues to rise, intelligent power monitoring and energy-saving management of communication base stations have become the research direction of various operators.

1.At the same time, the current power usage of tower base stations has the following problems:

Electricity stealing by related personnel:

Corresponding personnel will rely on the power supply system of the base station to connect privately used equipment.

2.Non-production energy consumption remains high:

According to statistical analysis, the average electricity expenditure of each base station air conditioner accounts for about 54% of the entire base station electricity expenditure. Air conditioners have become the main power-consuming equipment in the base station computer room.

3.Poor system linkage:

The base station equipment and lines cannot be controlled remotely, and the corresponding personnel cannot be notified and measures taken immediately when the line fails.

4.The number of base stations is large, the operation and maintenance burden is heavy, and the efficiency is low:

The existing base station power supply system still cannot meet the increasing needs of users for intelligence, informatization, visualization, and easy maintenance. There is no pre-perception and judgment on the hidden dangers of the battery in the system, and the operation and maintenance personnel are required to continue to the scene Perform operation and maintenance services, and the operation and maintenance efficiency is low.

Relying on strong R&D strength and rich industry experience, Acrel pay attention to improve the situations from both software and hardware aspects.
