The present invention relates to a kind of temperature control system, is specifically a kind of new distribution type cloud computing center temperature control system.
Cloud computing center, according to size, can be made of, its electric energy power consumption can a hundreds and thousands of or even up to ten thousand data server
Up to megawatt (MW) level, annual required energy consumption is quite surprising.The power consumption of cloud computing center is in addition to information technoloy equipment, its air conditioner refrigerating system
System also account for sizable ratio.The energy consumption tune that tens of data centers are made according to Lao Lunsi National Laboratories of the U.S. 2007
Look into, the power consumption profile of data center is：Information technoloy equipment accounts for 46%, and refrigeration system accounts for 31%, UPS (uninterrupted power source) and accounts for 8%, illumination
Account for 4%, it is other to account for 11%.For energy-saving and emission-reduction, in addition to optimizing the hardware design of information technoloy equipment, reducing air conditioning energy consumption is also
The energy saving key of cloud computing center.
Traditional data center makes every information technoloy equipment obtain required minimum refrigeration using the method for average refrigerating capacity
Amount, to ensure the reliability service of information technoloy equipment and whole cloud computing center, but since cloud computing center can be distributed because of server space
The change of the unbalanced and amount of traffic carried of server temporal skewness weighing apparatus, it is traditional based on average refrigerating capacity
Design of air conditioning, its refrigerating capacity redundancy is excessive, causes system excessively to be freezed problem, and the energy consumption for reducing system utilizes
Rate.
Goal of the invention：The present invention utilizes the problem of low for existing cloud computing center temperature control system energy consumption, it is proposed that a kind of

The effect of energy-saving and emission-reduction.
In order to solve the above-mentioned technical problem, present invention employs following technical solution：
A kind of new distribution type cloud computing center temperature control system, it includes distributed optical fiber temperature transducer system, described
The sensor fibre of distributed optical fiber temperature transducer system is arranged at the server of cloud computing center or server internal, distribution
The data acquisition and procession device of formula optical fiber temperature transducer system is connected with the air-conditioner central control system of cloud computing center, empty
Air-conditioner controller of the central control system respectively with each server is adjusted to be connected.
In the present invention, further, the distributed optical fiber temperature transducer system is single port distribution type fiber-optic
Temperature sensor system or dual-port distributed optical fiber temperature transducer system.
In the present invention, further, the sensor fibre is bend insensitive fiber ring.
Beneficial effect：Due to using DTS, the temperature information of each server of whole cloud computing center can Real-time Feedback arrive
Central air conditioning system, if certain server is extremely busy, its power consumption is with regard to big, its corresponding neighbouring temperature will rise, center
Air-conditioner control system knows the information at once by DTS, so that it may increases the air conditioner refrigerating amount near the server, ensures the service
The reliable and stable operation of device；On the contrary, if a certain server is very not busy, the temperature near it can generally be less than the average temperature of system
Degree, so we can reduce its refrigerating capacity.So cloud computing center central air conditioning system, can be to every by DTS
Server carries out accurate real time temperature control, and control accuracy can be better than 0.5 degree Celsius and (be specifically dependent upon the measurement essence of DTS
Degree), the overall energy consumption of central air conditioning system can be reduced, while the operational reliability of cloud computing center can be improved.In addition, edge
The each point temperature information of optical fiber, can be distributed the temperature space of whole cloud computing center by simple one-to-one relationship
Situation, projects to the monitoring center of cloud computing center, so as to the temperature space information of very clear whole cloud computing center.

The principle of distributed optical fiber temperature transducer system (DTS) is to be based on Raman (Raman) non-linear backscattering, i.e.,
Under the action of powerful pulsed light, inside of optical fibre can produce two new optical frequency anti-Stokes (anti-stokes) and this support
Ke Si (stokes).The two new optical frequencies are in the left and right of original signal optical frequency (at a distance of tens nanometer).In Stokes frequencies
Signal is less sensitive to the temperature on optical fiber, and the signal in Anti-Stokes frequencies is more sensitive to the temperature on optical fiber.This
Temperature change of the signal than just having reacted optical fiber in the two new frequencies of sample.Optical fiber is both transmission medium and passes in systems
Feel medium, the intensity backwards to Raman anti-Stokes lights in optical fiber has been modulated in the temperature field of spatial points residing for optical fiber, through ripple
Division multiplexer and photoelectric detector acquire space temperature information, then through signal processing, it is after Demodulation Systems that temperature information is real-time
Extracted from noise.Spread speed using light wave in optical fiber and the time interval backwards to optical echo at the same time, to institute's thermometric
Degree point is positioned.
