Electric Monitoring Solutions for Mobile Towers/Base Stations

I. Background

The year 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 are 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 pays attention to improving the situations from both software and hardware aspects.

II. Applications

1. One of the tower companies in the United States integrates remote power monitoring systems for towers in Africa areas. It requires to be connected into a large number of AC and DC collection meters to provide real-time, accurate and stable basic-level data for it to more effectively grasp and analyze power usage. Relying on 17 years of good reputation and strength in the power industry, Ankerui has a rich product line, excellent product quality, fast delivery cycle, strong technical support, and has passed multiple on-site field tests and compared multiple brands. Stand out, become the high-quality supplier of the group, and reach a strategic cooperation agreement.

2. China Tower Co., Ltd. is a large state-owned communications tower infrastructure service company funded by China Mobile Communications Co., Ltd., China United Network Communications Co., Ltd., China Telecom Co., Ltd. and China Guoxin Holdings Co., Ltd. The company is mainly engaged in the construction, maintenance and operation of base station supporting facilities such as communication towers, high-speed rail subway public network coverage, and large indoor distribution systems. In 2017, Acrel customized and developed DC meters according to the requirements of Q/ZTT 1017-2015 "Technical Specifications for Base Station AC Smart Meters" and Q/ZTT 2205-2017 "Technical Requirements for Base Station DC Energy Metering Modules", which has been widely used in this project.
