Abstract

The invention relates to a thermostatic control device used in a distributed optical fiber temperature sensor system and a thermostatic control method thereof, characterized by comprising a temperature control apparatus; a heat insulation thermotank; a first temperature survey meter, arranged on the inner wall of the heat insulation thermotank and connected with the temperature control apparatus; a heat exchange bottom plate, arranged on the inner wall of a first side plate of the heat insulation thermotank; at least one refrigerator, which is arranged on the first side plate of the heat insulation thermotank, and is provided with a signal input end being connected to the temperature control apparatus as well as a cold end being connected to the heat exchange bottom plate.; at least one heater, the signal input end of which is connected with the temperature control apparatus, arranged on the first side plate of the heat insulation thermotank and connected with the heat exchange bottom plate. Compared with the prior art, the invention has the advantages of high control precision and strong adaptability.

Description

technical field [0001] The invention relates to a constant temperature control device used in a distributed optical fiber temperature sensor system and a constant temperature control method of the constant temperature control device. Background technique [0002] In the distributed optical fiber temperature sensor system, since the photoelectric processing components and weak signal processors involved are very sensitive to temperature changes, these devices need to be placed in a constant temperature environment to work. At the same time, because the distributed temperature calculation requires the system to provide a standard temperature sampling, because the measurement accuracy of the system depends largely on the accuracy of temperature sampling in addition to the influence of the accuracy of signal acquisition and processing, which requires the dynamics of standard temperature sampling. The error should be as small as possible. [0003] But there is no constant temper...
