Study of Key Technology in High-speed Data Collection System for CODAD

High-speed real-time acquisition and storage of engine speed,fuel rack and engine output torque was realized by using the high-speed data acquisition card.The data filter,dynamic waveform display and analysis system was designed and a new solution for displaying and analyzing speed was proposed.It was verified by test on engine that this system is normal in operation and stable in collecting parameters signals,thus is helpful in studying parameters monitoring and control during the compounding process of diesel engines.
