摘要
介绍了一种基于FPGA的多通道数据采集模块的实现方案。采用多块采集卡、多个FPGA控制芯片的设计方式,从而整体提高了采集的速度与精确度;采用模拟开关级联的方式,精确控制每块采集卡24路通道切换的地址变化,使AD按照采样频率要求进行精确采集。该设计方案结构灵活、控制简单、可靠性高,并且通过实验验证其功能的正确性,完全满足工程实践的要求。
A scheme of multi-channal data acquisition module based on FPGA is introduced. The use of multiple acquisition cards and multiple FPGA control chips enhance the record speed integrally. Adopt the method of analog switches connection, and control 24-channel switch of each acquisition card precisely to make AD sample accurately as request. The design of a flexible structure, simple control, high reliability, and experimental verification of the correctness of its functions, fully meet the requirements of engineering practice.
