Paper Abstract

A high speed data sampling and processing system applied to investigate engine moving parts is introduced in this paper. According to the engine working features the data sampler of the system makes use of engine crankshaft angle signals as sampling pulse it can control the sampling range accurately and make it possible to sample in designated range of engine working cycle. High speed A/D conversion chip and DMA transmitting method are used so as to obtain the high sampling efficiency and high sampling rate and meet the needs of high speed sampling and processing of engine dynamic signals. Some distinguished processing methods are also introduced in this paper which include digital filter technique chain fraction integration etc. A data sampling and processing example is given combined with the measurement of engine valve train'' s dynamic parameters.
