一种陀螺信号数据采集系统的研制

Development of a Gyro Signal Data Acquisition System

本文介绍了一种基于Windows+RTX陀螺信号数据采集系统,该系统实现壳体翻滚角及陀螺信号1ms实时采集及伺服解算。软件采用Windows操作系统+RTX实时扩展子系统的方式,增加系统的可靠性和稳定性,即控制管理计算机在RTX实时系统的调度之下不但实现控制管理功能,还要实现闭环系统的实时控制解算功能,数字采集及解算周期可以小于1ms。此系统可以脱离运动平台独立运行,可靠性高,采用开放性结构,易于扩展。

A gyro signal data acquisition system based on Windows+RTX was introduced,which is composed of hardware acquisition board and acquisition software.It mainly realizes the shell rolling angle and gyro signal 1ms real-time acquisition and service solution.In the composition of the software system,the way of Windows operating system+RTX real-time extension subsystem is adopted to increase the reliability and stability of the system.That is,the control and management computer not only realizes the control and management function,but also realizes the real-time control and calculation function of the closed-loop system under the degree of RTX real-time control and system.The digital acquisition and calculation cycle can be less than 1ms,the system can run independently from the motion,has high reliability,adopts open structure and is easy to expand.
