摘　　要：光纤陀螺漂移的稳定性与温度之间存在很大关联,温度场的不均匀将影响光源稳定性等参数,从而引起陀螺漂移;同时由于环境温度不均匀也会造成陀螺参数标定测试结果不准确。因此设计精密温控系统来保障光纤陀螺等精密惯性元件的工作环境,对于提高陀螺精度具有重要的实际意义。本文以实际工程为背景,设计光纤陀螺仪温度控制系统,以模块化的设计实现工作环境温度的精密控制。本系统具有较强的通用性,模块化的设计可使系统便于安装和调试,最终能够使系统测温精度达到要求。The stability of the fibre optic gyroscope drift is concerned with the temperature of working envi-ronment, whose nonuniform-distribution affects the stability of the gyroscope, and then causes its drift, as well as the inaccuracy in parameters. So the design of a precise system to control its environment temperature is important to practical engineering. This paper, based on a college project, designs a precise temperature control system for the gyroscope, with modules for a precise control of the temperature of working environment. The system has strong generality, and the design of its modules makes it easy to install and debug. The results show that the tem-perature measurement can be precisely reached.
