摘　　要：介绍了一种基于FPGA的多通道数模信号实时采编存储系统的设计与实现;分别从总体设计、硬件设计和软件实现等方面进行描述;系统以FPGA为核心控制芯片,实现了4路RS485总线数字信号与28路模拟信号的实时采集、混合编帧与数据存储,并通过具有USB2.0接口微控制器CY7C68013完成与上位机的通信;本系统采用模块化设计方法,功耗低、采集精度及可靠性高、实时性好,具有广泛的实用性与通用性。The design and implementation of digital and analog signal real--time acquisition and storage system based on FPGA is intro- duced in this paper. It is described from the aspects of overall design, hardware design and software design. The system can complete real-- time acquisition, editing frame and data storage for 4 channels of digital signals in RS485 and 28 channels of analog signals. It can communi- cate with computer on USB2.0 by the chip CY7C68013. The system applied by the design method of modularization has characteristics of low power consumption high precision and high reliability. Thus, it has a wide range of application.
