摘　　要：研究了基于ARM9的近程无人机数据采集系统,重点阐述了高级精简指令集机器(Advanced RISC Machine,ARM)系统中执行直接内存存取(Direct Memory Access,DMA)操作的工作原理,并利用DMA技术设计了基于S3C2410和现场可编程门阵列(Field-Programmable Gate Array,FPGA)的采集同步数据并转成以太网数据的系统,给出了数据采集接口设计方案。在Altera公司的EP1S20F484上,实现了在Linux2.6下的设备驱动。测试结果表明系统工作稳定,以FPGA与ARM相结合的双核嵌入式处理器模式为无人机测控领域提供了一种高效的方法。This paper studies the data acquisition system of short-range UAV based on ARM9 and introduces in detail the operating principle of DMA channel in ARM system.A system,which collects and transmits synchronous data to Ethernet based on S3C2410 and FPGA,is designed using DMA mode,and a design scheme of data collection interface is presented.The design of the driver program on Linux2.6 kernel on chip EP1S20F484 of Altera Company is implemented.The experiment results show that the embedded acquisition system operates stably and provides an effective method for UAV TTC domain by a dual core embedded processor combining FPGA and ARM.
