Ant-i shock data recorder is widely used in flying data recording of cruise missiles,it has many signal recording channels and it will record large amount of data.Reading a mount of data quickly from data recorder and saving data to computer is a challenge.Taking LABVIEW8∙5as software development platform,using USB-bus as data call-back transferring bus,the software and hardware interface technique,data dynamic saving and high-speed recalling techniques of ant-i shock data recorder are introduced in this topic in detail.The function of high-speed data transferring with speed of1MB/s from recorder hardware to computer is realized effectively.Thus,the high-speed data recalling,data saving and data analysis problems on test spot are resolved.Missiles flying experiment application indicated that this system runs stably and reliably,the data is returned back rapidly and correctly.
