Electric Monitoring solutions for Mobile Towers/base stations 

I.背景信息：

2020年5G元年，通信行业承蓬勃发展之态，各大运营商和铁塔集团在布局新一代通讯基站。基站用电量不断上升，通信基站智能化电力监控及节能管理已成为各运营商企业的研究方向。

而同时，目前铁塔基站电力使用存在以下问题：

1.相关人员偷电行为：

对应人员会依靠基站的供电系统，私自接搭自用设备。

2.非生产能耗居高不下:

据统计分析，平均每个基站空调的电费支出约占整个基站电费支出的54%左右，空调成为基站机房中的主要耗电设备。

3.系统联动性差:

无法远程控制基站设备和线路，线路出现故障时无法立即通知相应人员并采取措施。

4.基站数量大，运维负担重、效率低：

现有的基站供电系统依然无法满足用户对智能化、信息化、可视化、维护简便等的日益增加的需求，对系统中蓄电池的故障隐患等没有预先感知和判断，需要运维人员不断的到现场进行运维服务，运维效率低。

安科瑞凭借强大的研发实力，和丰富的行业经验，从软件、硬件双方面着手，致力于解决铁塔基站用电面临的问题。

I.Background

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.
