摘　　要：针对火控系统信息的应用需求和信号特点,提出了一种基于STM32+FPGA的数据采集系统设计方案。利用STM32丰富的外设功能和数据处理能力,以及FPGA灵活的逻辑可操控性,实现了火控系统多通道,多类型信号的实时采集,其中FPGA负责采集控制和数据缓存,STM32负责数据处理和与上位机的通信传输。在介绍系统总体方案的基础上,进一步讨论了STM32与FPGA通信接口、AD时序控制、数据缓存等关键部分的设计,通过实验验证了设计的可行性和有效性。For information application requirements and signal characteristics of an fire control system, a design of data acquisi- tion system based on STM32＋FPGA is presented. By using the rich peripherals and data processing capabilities of STM32, and the flexible logic maneuverability of FPGA, a multi-channel and multi-type real-time signal acquisition system is achieved, in which FPGA is responsible for acquisition control and data caches, and STM32 is responsible for data processing and transmis- sion of communications with the host computer. On the basis of introducing the overall program, the design of STM32 and FP- GA communication interface, AD timing control, data caching, and other key parts are further discussed. Finally, the feasibility and effectiveness of this design is verified by experimental tests.
