摘　　要：针对民机可配置模拟量采集需求,设计了一种基于高性能Zynq的多通道模拟量采集接口电路。硬件部分,通过PL控制多路选择器,实现模拟量的单端/差分采集,以及通道切换;软件部分,采用建立模板函数库结合配置表的方法,实现对不同模拟量系统的可配置采集。经验证,该接口为系统开发提供了便利,提高了系统开发效率。In view of the configurable analog acquisition requirements,a multi-channel analog acquisition circuit is designed based on high performance Zynq.Multiplexer is used to achieve single-ended/differential analog signal acquisition and channel switching;Template function library is used to the system's configurability.It is verified that the interface presented in this paper provides convenience for system development,and improves the system development efficiency.
