基于TMS320C6713和MAX1420的高速数据采集系统设计

Design of a high speed data acquisition system based on DSP and MAX1420

介绍数据采集系统的发展状况,分析高速数据采集系统应满足的性能要求,完成高速数据采集系统的设计方案,给出系统硬件结构图及主要模块电路,说明系统软件的结构与主要程序流程。系统使用MAX1420为A/D转换器,DSP(TMS320C6713)为中央控制器件,选用FT245BM完成USB2.0接口,使用大容量Flash备份数据。测试表明,本系统可以实时完成高速数据采集和存储。

This paper introduces the status of the data acquisition system,analyses the function demands of the high speed data acquisition system,and accomplishes the corresponding design scheme.The hardware of the system frame and the circuits of the main module are given in detail.The structure of the system software and the flow-chart of the main program are explained.In this system, MAX 1420 is used as the analog to digital converter, DSP（TMS320C6713）as the CPU,FT245BM to realize the USB2.0 interface function,and large-capacity memorizer to backup the sampling data.The system testing shows that the system can real time complete the data acquisition and storage.
