摘　　要：根据卫星姿轨控分系统(attitude and orbit control system,AOCS)的地面测试需求,提出了一种基于PXI(PCI Extensions for Instrumentation)总线协议的多通道信号采集控制系统的设计方案,该方案针对以往的采集控制系统在采集效率和实时性方面的不足进行了改进,并进行实际的项目开发。实践表明该系统的采集精度和实时性满足测试要求,并且结构灵活、具有良好的可扩展性和通用性。A multi-channel signal acquisition and control system based on PXI bus was developed in this paper for the attitude and orbit control system of satellite ground testing.This system seeks to improve the acquisition and real-time capability which is the shortage of previous signal acquisition and control system.We talked about the hardware configuration and software implementation of the system in the paper.The performance of the system is very good and it has the advantage of flexibility and expansibility.
