摘　　要：本文介绍了以PCI接口芯片CH365为控制部件、以CPLD EPM7128S为逻辑部件的PCI数据采集卡的设计。该数据采集卡实现了由ISA接口的采集卡到PCI接口的采集卡的直接升级,无需修改使用ISA接口卡的应用程序。给出了系统设计电路和软件设计方案。该数据采集卡具有使用方便、硬件设计简单、成本低、体积小的特点。The data collection card with PCI interface chip CH365 as control component and CPLD EPM7128S as logic system is introduced. This design realizes upgrade the data collection card from ISA interface to PCI interface and the application of ISA card can use without changing. Design scheme of circuit and software are provided. The card has many features including easy using, small volume of hardware, low cost and so on.
