基于DSP的高速同步数据采集系统的设计与实现

The design and realize of a high speed synchronous data acquisition system based on DSP

在自动控制、通信等应用领域中,某些情况下需对操作现场进行瞬态信号测试,有时也涉及对多路信号进行故障诊断和分析。这些场合都需要系统提供多通道同步高速数据采集与处理单元,研制了一种低成本、多通道同步采集的数据采集和处理系统。该系统是以同步采样芯片MAX125为A/D采样芯片、定点DSP芯片TMS320LF2407为主处理器,它具有体积小、功耗低、使用方便、处理数据量大、处理精度高、性价比高等优点。

In the automatic control, communications,and other applications,in some cases,the need to operate on-site testing of transient signals,Sometimes involves multiple signals fault diagnosis and analysis.These occasions need to provide multi-channel high-speed synchronous data acquisition and processing unit, So this paper designs low-cost,multi-channel synchronous data acquisition and processing system..Such system takes synchronous acquisition chip Max125 as A/D acquisition chip and fixed point DSP chip TKS320LF2407 as main processor,it has the advantages of small size,low power consumption and easy to use,lt can deal with large amounts of data with high accuracy,and high cost.
