基于级联模式的多通道数据采集系统设计

Design of Multi-channel Data Acquisition System Based on Cascade Model

针对多通道多种类混合信号采样的需求,文中提出了一种基于级联模式的数据采集系统。该系统以FPGA作为核心控制单元,以级联方式链接信号调理卡与主控制卡,实现了多路混合信号的并行采集。该模式降低了采集系统的复杂性,最大程度地保证了系统的通用性与灵活性,具有很高的应用价值。

To meet various kinds of multi-channel mixed-signal sampling requirements.The paper proposes a data acquisition system based on the cascade model.The system uses FPGA as the core control unit and uses cascade model links the signal conditioning card and the main control card.It implements the parallel multi-channel mixed-signal acquisition.The model reduces the complexity of the acquisition system and maximum degree ensure that the system versatility and flexibility.It has a very high application value.
