Abstract

The invention relates to a driving and temperature controlling system and method for a rotary split-type pneumatic Stirling cryocooler. The system comprises an external direct-current main power, and further comprises a first DC-DC conversion module, a second DC-DC conversion module, a semi-H-bridge power amplification module and a direct-current brushless motor Hall signal detection module, wherein the first DC-DC conversion module and the semi-H-bridge power amplification module are separately connected with the external direct-current main power; the second DC-DC conversion module and the direct-current brushless motor Hall signal detection module are separately connected with the first DC-DC conversion module; the second DC-DC conversion module is further separately connected with a temperature-measurement diode temperature signal detection module and an MCU module; the MCU module is separately connected with the direct-current brushless motor Hall signal detection module, the temperature measurement diode temperature signal detection module and the semi-H-bridge power amplification module; the semi-H-bridge power amplification module is connected with the rotary split-type pneumatic Stirling cryocooler; and the rotary split-type pneumatic Stirling cryocooler is connected with the temperature measurement diode temperature signal detection module and the direct-current brushless motor Hall signal detection module.

Description

technical field [0001] The present invention relates to the fields of refrigeration and cryogenic engineering and automatic control, and more specifically relates to a drive and temperature control system and method for a rotary split pneumatic Stirling refrigerator. Background technique [0002] Since the Dutch Philips laboratory successfully developed the practical Stirling refrigerator in 1954, the Stirling refrigerator has gone through half a century of development, and its structural form has evolved from integral to split. The rotary split Stirling refrigerator is an intermediate product between the rotary integral type and the linear split Stirling refrigerator. There are mature processing and assembly technologies for rotary integral Stirling refrigerators, and the cost is lower. [0003] The core device of the infrared detection system is the infrared detector, and the cryogenic refrigerator is an important part of the infrared detector, which is used to realize th...
