数据采集系统在固体火箭发动机试验中的应用

摘要

重点介绍HP VXI总线数据采集系统在固体火箭发动机试验中的应用，其中包括数据采集和处理程序，及VXI设备的基本性能调试。并对软件设计思路和相关问题进行了讨论。通过与原有数据采集系统进行试验比较，表明该测试系统合乎程序动态试验的技术要求，性能优异。%The application of the HP VXI Bus data acquisition system to the solid rocket engine test rig,including the data acquisition and processing programs and the adjustment of the basic performance of VXI device,is introduced emphatically.The idea and relative problem of sofware design are discussed.Through the test comparision with the primary data acquisition system,it is shown that this system meets the technical requirement of the dynamic test and the performance is exellent.
