摘要
介绍了一种基于PC104总线的多通道高速同步数据采集系统的设计方法,在硬件设计上采用四通道模数转换芯片AD7865组成模数转换模块,利用CPLD组成功能电路模块进行逻辑控制与数据传输的实现,简化了硬件电路,同时也提高了其设计的灵活性,具有采集数据速率快,准确率高的优点。
A multi-channel and high-speed synchronous data acquisition system based on PC104 bus is intro- duced. The analog and data signal conversion module performed by 4 passageway conversion chip AD7865, the data transmission and the control logics performed by CPLD in hardware simplify the cir0cuit greatly. It has the advantage of flexible design, high accuracy and high speed.
