Abstract
In order to achieve the energy saving and management, this article proposes an IoT-based energy-saving and management system for Telecom operators' remote computer rooms (RCRs). Firstly, a management system based on IoT technology for RCRs is designed. By using technologies such as embedded systems, sensor technology and Java Web, this system realizes equipment management and real-time data visualization of RCRs. Then, a simple but effective air conditioner energy-saving algorithm, called ET algorithm, is developed. Without causing high investment cost, ET algorithm minimizes the energy consumption of air conditioners which accounts for nearly 40% of total consumption, and thus improves the overall energy efficiency of RCRs. Moreover, the proposed system has been implemented at many Telecom operators' RCRs distributed at different regions in Guangdong Province of China, and stably operating for more than two years. Experimental results show that the proposed system not only effectively manages and monitors RCRs, but also achieves 16.64% energy-saving effect.
Highlights
With the advent of 5G era, energy consumption in operator field has been growing rapidly, due to an explosion in network flow of base station
Researchers predict that the annual growth rate of energy consumption in operators’ remote computer rooms (RCRs) will reach 7.5%-20% [2]
To the best of our knowledge, this study provides the following two contributions: (1) we propose an Internet of Things (IoT)-based management system for Telecom operators’ RCRs
Summary
With the advent of 5G era, energy consumption in operator field has been growing rapidly, due to an explosion in network flow of base station. Adjusting the working time of ACs without sacrificing the required temperature is a simple and cost efficient way to lower the energy consumption of ACs. For the management of remote CRs or data centers (DCs), existing references have developed some remote management systems for CRs or DCs, which have good management performance but low or even no energy-saving ability. Marcos-Jorquera et al [18] proposed a smart monitoring model for DCs based on embedded technology, which realized the management of equipment This model does not involve any energy-saving algorithms. Without causing high investment cost, ET algorithm minimizes the energy consumption of ACs by controlling their working time, and improves the overall energy efficiency of RCRs. The rest of the paper is arranged as follows. The prototype and design of each sensor and actuator will be described in detail
