Optical Dimension Energy Management system to create a safe and energy-saving data center

With the maturing of virtualization technology, the development of cloud computing, large data business, the increasing demand of Internet customers, and the government's policy guidance, China Data Center has ushered in a big development. It is expected that by 2016, China's IDC market will reach 54.83 billion yuan, the growth rate will rise more than 30%. In such a large environment, data center of the building and transformation of the room is also in full swing. At the same time, the data center scale expands rapidly, the server processing ability is more and more strong, the data storage equipment's capacity is more and more big, the equipment's integration is more and more high, the calorific value is more and more concentrated, to the air conditioning refrigeration ability request is more and more high, the data center room Therefore, it is important to control the operation state of air conditioner accurately, control the temperature of the room, and realize the energy-saving of the data center.

In the typical data center energy consumption, the air-conditioning system is the second biggest energy consumption in the data center room, which consumes about 37% of the total energy consumption required by the data center room. However, in fact, many data centers in China, air-conditioning energy consumption ratio is far more than this value, and some even more than 60%. Therefore, energy saving from air conditioning system to start, both large energy-saving space and full of urgency.

In response to the problems existing in the data center temperature monitoring, and responding to the national call for energy conservation and emission reduction, Shanghai optical-dimensional Communication Technology Co., Ltd. developed a data center energy management system based on distributed optical fiber temperature measurement technology and improved CFD algorithm. The system can collect data center's temperature, humidity, wind speed and so on, graphically reproduce the temperature distribution of the power line in the data center, the temperature field distribution of the computer room environment and the micro-environment of the cabinet, the wind speed distribution of the computer room, the linkage air conditioning control system, the fan control system To realize the accurate positioning and fast cooling of the local hot spot of the data center, to realize the precise control and energy saving of the air-conditioning system, and to create a safe and energy-saving data Center for you.

The whole architecture of the system adopts distributed three-layer modular structure: Sensing collection layer, data transmission layer and management operation layer.

Sensing collection Layer

The sensing collection layer mainly refers to the optical fiber temperature measuring system which can be used to monitor the data center line temperature, the data center ambient temperature, and the micro environment temperature of the cabinet, which is used to monitor the high precision capacitive humidity sensor of the room environment, the new type of heat-film wind speed sensor and the data acquisition In the collection of temperature data, the system realizes the perfect environment temperature monitoring from the computer room level to the cabinet level by using the distributed optical fiber temperature measurement technology, more accurate display of room temperature, which is conducive to air-conditioning temperature, humidity, wind speed more reasonable settings, so that air-conditioning refrigeration system more targeted, in improving the efficiency of refrigeration at the same time, Reduce energy consumption. Moreover, the distributed optical fiber temperature measurement system can also be used to monitor the temperature of power line in data center, which makes the electricity more safe and reliable.

Optical fiber temperature measurement system is the core product of optical-dimensional Communication Technology Co., Ltd with independent intellectual property rights. Compared with the traditional electronic temperature sensor, it has obvious advantages: distributed continuous measurement, can monitor the temperature of the optical fiber in real time, and can locate the spot of the local hotspot accurately, without electromagnetic interference, good stability, small size Can be installed to the gap, small holes, etc., do not occupy space, as long as the fiber is not damaged by external forces, can be maintenance-free. The following are the main technical specifications of the optical fiber temperature measurement system:

L Measuring Distance: 2 km/km

L channel number: 1 Channel/2 channel/4 channel (customizable, up to 16 channels)

L Temperature range: conventional -20~+120°c, depending on the choice of temperature-sensing cable

L Response Time: 5 sec/

L Spatial resolution: 1 m

L Temperature Resolution: 0.1°c

L Temperature accuracy: ±1°c

L Positioning accuracy: ±1 m

In addition, the system has a good scalability, according to user needs for capacity expansion, such as the addition of gas monitoring module, dust monitoring module, you can achieve the data center environment all-round multi-level real-time monitoring.

Data transfer Layer

The data transmission layer mainly refers to the information of the field collection layer passed through the data conversion, passed through TCP/IP and network equipment to management operation layer. It mainly includes the Communication Transformation module, the Protocol transformation server, the network Exchange equipment and so on network medium.

Manage the layer of operations

Management operation layer is the core of the whole data center energy consumption management system, through the data transmission layer upload, processing, according to the scientific control strategy to make judgment, and the air conditioning system and fan system for accurate control, so that its coordination, and thus achieve better environmental control and energy saving purposes.

For the convenience of user's operation management, this system uses specialized operation software, it has the following function characteristic:

L use b/s architecture, all functions through IE, such as browser rendering, do not need to install client software, with remote debugging, configuration functions;

L with real-time three-dimensional display temperature field, plane display temperature field, humidity field and wind speed field function;

L with alarm and alarm record tracking function;

l have data query and historical curve real-time display and save function;

L have the function of air condition inquiry;

L with linkage air-conditioning control system and fan system, timely reduce the local temperature overheating, real-time accurate control of air-conditioning system running state function;

Using modular, open software architecture, the function of modular expansion is convenient.

The above optical Dimension Data Center Energy Management system can be widely used in telecom, banking, taxation, insurance, electricity, education and scientific research, transportation, petrochemical, government agencies, medicine, tobacco, factories, community and other industries IDC data center and monitoring room. Optical-dimensional company based on the advanced nature of the application of a number of patents have been authorized, with complete intellectual property rights. The system in the domestic access to a number of successful application cases, including a first-line operator in Shanghai IDC key Room Air-conditioning Group control system, a domestic University Network center IDC Room. Application practice proves: This system can better monitor the environment temperature of the computer room, solve the local hot issues of the computer room; This system can make the air-conditioning system in the best energy-saving state, to achieve energy-saving emission reduction; The system has a good expansibility, to meet the needs of follow-up information on demand expansion, the system optimizes the maintainability and The whole system runs stably, the reliability is strong, the system construction installs is simple, the transformation process does not affect the data center normal operation, the time limit is short.
