摘要
研制了一种进行船用计程仪速度标定的高精度旋转系统．系统由旋转机构、直流电机驱动装置和计算机控制系统组成．通过采用高精度的硬件定时器实现转速的准确测量,利用windows平台下的多媒体时钟进行定时采样及实时控制,使旋转系统的转速控制精度达到了1‰FS．
A new high-precision rotation system used for marine log calibration is developed The system consists of rotating mechanism, DC motor driving component and computer control system. In order to achieve the precision request of control system, the inter＇nat timer on the counter board is used to lock the counter precisely： and the multimedia timer in the window s system is used for sampling and controlling. The result of testing data proves that the system is feasible and shows that the precision of the system reaches 1‰FS.
