PIGA自动化实时测试系统的设计与实现

The Design and Implementation of an on-Line Automatic Testing System for PIGA

本文介绍一种针对摆式积分陀螺加速度计（ＰＩＧＡ）的输出与回路状态变量进行实时测试的自动化测试系统。根据对测试系统的测试要求和多路待测试的信号特点，设计了一套集外中断计时、ＧＰ—ＩＢ总线接口、实时数据与图象动态显示、完美的用户界面于一体的测试软、硬件，并对采样数据的处理进行了研究，该实时测试系统在工程实际应用中精度较高。

In this paper an on-line automatic testing system is introduced which detects the output and loop state variables of a pendulous integrating gyro accelerometer (PIGA) by means of computers.According to testing system requirements and features of multi-loop signals,a set of testing hardware and software that contains outer interrupt timing, GP-IB bus interface,on-line display of dynamic data and graph,perfect user interface is designed.The processing of sampling data is also discussed.This on-line testing system has high precision during engineering practice and acquires relatively excellent performance.
