Description

Cloud Management System for Environment and Cooling

(1) Technical field

The present invention relates to a cloud management system, in particular to a cloud management system applied to air conditioning systems in environments such as communication base stations.

(2) Background technology

As the global energy becomes increasingly tense, China has more urgent requirements for energy conservation in social construction. Among them, the high-speed development of the telecommunications industry is more urgent to save energy. Operators accelerate the construction of base stations and computer rooms, but they also have to face high energy consumption.

For example, the total power consumption of China Telecom in 2009 was about 9.8 billion kWh, an increase of 41.6% over 2008. Among them, the power consumption for production is dominated by the growth of base stations and data center computer rooms, which have increased by 209% and 21% respectively compared with 2008. At the same time, some equipment technologies are backward or outdated; there is a lack of accurate classification and sub-item energy consumption data, and there is a lack of quantitative evaluation methods for energy conservation results; there is no scientific energy conservation diagnosis, and the operation of key energy-consuming equipment is not scientific; there is a lack of unity in energy consumption and energy conservation. monitoring and management. Therefore, it is imperative for telecom operators to take energy-saving measures.

Using energy-saving control system to improve existing equipment to reduce its energy consumption is currently a commonly used method. For telecommunications, dynamic energy-saving control has not yet been adopted with uncertain technology. Based on the previous "communication base station fresh air/air conditioning energy-saving control system", this patent further controls the power consumption of equipment rooms, buildings and other facilities.

Energy is the material basis necessary for human survival and social development. In the 21st century, energy shortage has become a worldwide problem for the economic development of all countries. The national "Eleventh Five-Year Plan" outline requires that during the "Eleventh Five-Year Plan" period, the energy consumption per unit of added value should be reduced by about 20%, and the total discharge of major pollutants should be reduced by 10%. Among them, the assessment of electricity consumption is more stringent. The real environment is an uncertain environment. For uncertain (fuzzy, random, fuzzy random, random fuzzy) environments, the power consumption of business halls in the telecommunications industry, independent transmission rooms, office buildings, computer room buildings, and communication base stations, etc. Data acquisition, analysis and control. The developed energy-saving control system can effectively save energy, reduce air pollution and CO2 emissions.

At present, air conditioners are used for cooling in the business halls of the telecommunications industry, independent transmission machine rooms, office buildings, machine room buildings, and communication base stations, resulting in manual temperature setting and real-time monitoring during equipment operation, resulting in equipment testing and maintenance. Difficult, in addition, during the operation of the equipment, the air filter does not make full use of the external ambient temperature, and does not consider the seasonal changes and the temperature difference between day and night, resulting in a lot of energy waste.
