Non-magnetic electrical heating system used for atomic spin gyroscope

Abstract

A non-magnetic electrical heating system used for an atomic spin gyroscope comprises a non-magnetic cavity, a heating driving subsystem and a temperature control subsystem. The non-magnetic cavity is composed of an electrical heating film, an inner heat conduction cavity, an outer thermal insulation cavity, a vacuum chamber, a support, a temperature sensor and the like. The heating driving subsystem is composed of a temperature switch and a direct current power source. The temperature control subsystem is composed of a single chip microcomputer, a DAC chip and a peripheral circuit. The atomic spin gyroscope is heated and temperature is controlled by means of a method which comprises the steps that the heating driving subsystem carries out heating in a high-power and rapid mode until a preset temperature of the atomic spin gyroscope is reached, and the temperature control subsystem is switched to through the temperature switch to control the working temperature of the atomic spin gyroscope in a low-power mode. The non-magnetic electrical heating system overcomes the defects that air flow disturbance exists, the temperature cannot be controlled, the size is large and integration is not easily caused by a traditional air flow heating device in the atomic spin gyroscope, isolates interference on performance of a magnetic shielding by a hot air flow, and has significant engineering practical value.
