在惯性测试设备控制系统设计中,角度编码器信号实时采集的设计是实现惯性测试设备角位置和角速率高精度控制的关键。区别于基于硬件实时采集的开放性差且电路复杂的方法,本文基于RTX+Windows系统平台进行实时采集。通过设计基于RTX的角度编码器信号实时采集硬件方案及接口驱动程序,实现了对惯性测试设备角位置的实时采集,并将该方法成功应用于转台角位置实时采集,有效满足对转台的实时控制要求。

In this paper,the real-time acquisition of angle encoding signal based on RTX is studied with inertial testing equipment as the object of application.In the design of inertial testing equipment control system,the design of angle encoder signal real-time acquisition is the key to realize the high-precision control of angular position and angular rate of inertial test equipment.Different from the method of poor openness and complex circuit based on hardware real-time acquisition,this paper carries out real-time acquisition based on RTX+Windows system platform.The hardware scheme and interface driver of real-time acquisition of angle encoder signal based on RTX are designed to realize the real-time acquisition of angular position of inertial testing equipment.The method is successfully applied to the real-time acquisition of the angular position of the turntable,and meets the real-time control requirements of the turntable.
