基于Windows平台的高精度定时的实现

High Precision Timer Based on Windows

针对转台控制系统中的实时时钟问题 ,本文给出了两种在Windows操作系统下实现高频精确的定时方法 ,即设备驱动程序法和高性能定时器法。这两种方法已分别应用于在某型天线罩测试转台和三轴倒挂仿真转台的实际应用中 ,实践表明 ,系统运行稳定 ,性能良好。

For the issue of real-time clock in turntable control system,two methods for implementing high frequency timer are given in this paper,one is Device Drivers Method,the other is High Performance Timer Method.These Methods have been used for certain radome test turntable and certain three axes simulation turntable respectively.These systems have favorable stability and performance in practice.
