Abstract

As to resolve the bottleneck problem in the serial interface mode of RS232 large-data real-time acquisition applied in vehicle velocity testing system,this paper presents a design scheme of the high speed data acquisition system based on TMS320F2812 chip of DSP and ISP1581 of high speed USB2.0.The design has the advantages of high sampling rate,strong data processing,high speed transmitting and etc,which is completely able to meet the needs of the bandwidths to transmit high precise real-time data.The practice proves that the data acquisition system absolutely fulfills the design request and is of some certain practical value.
