摘　　要：在船载测量伺服系统中,陀螺是保证稳定跟踪的重要工具。针对两组热备份陀螺中,信号检测及人工手动切换存在的不足,在理论分析的基础上建立了速率陀螺性能的数学模型,并利用Del-phi实现陀螺自动检测与切换,如遇主陀螺故障,切换至备用陀螺的时间由原来的1分钟缩短至5秒钟,在实际测试中收到较好的效果。The gyroscope is an important tool to keep stable tracking for ship - borne servo system. Aiming at the deficiency of signal detection and manual switch for two team rate gyroscopes, a mathematic model of the rate gyroscope performance is built based on theoretical analysis. The auto - switching and auto - de- tection of two rate gyroscopes is also realized through Delphi, and the switching time to spare gyroscope is reduced from 60minute to 5 seconds if the main gyroscope is failed. A good result in practice is achieved.
