摘要
为提高现有卫星测试系统的效率,对基于PXI总线的实时综合测试系统进行了研究。给出了测试系统的中央控制台、实时测试仿真单元和控制输出单元和辅助测试装置主要硬件构成,以及任务管理、实时测试仿真单元、控制输出单元和显示终端等软件组成。介绍了系统的工作原理,以及实时测控、多平台间实时数据共享交互等关键技术。结果表明,该系统从实时测试仿真单元信号采集至仿真运算结束的时间约1~10 ms。
To improve the efficiency of the present measurement system for satellite,the PXI-based real-time integrated measurement system was studied in this paper.The main composition of the system's hardware of the center control board,real-time measurement simulation unit,control output unit and auxiliary measurement device were given out,and so were the software of the task management,real-time measurement simulation unit,control output unit and display.The principle of the measurement system was introduced.The key technologies of real-time measurement,real-time data sharing and interaction among multiplatform were also given out.The results showed that it only need about 1~10 ms from the sampling of the real-time measurement simulation unit to the end of the calculation.
