摘要
以嵌入式系统为核心,详细阐述了一种用于导引头地面测试的嵌入式测试平台的设计方法。通过对测试需求的抽象,完成了测试数据采集、存储、传输和参数显示等测试适配接口的设计。硬件电路采用ARM9和FPGA的双核心控制器结构,软件采用嵌入式Linux作为操作系统,并在应用程序中采用多线程的设计方法。实践表明,本测试平台具有接口丰富、功能多样、可扩展性强的特点,可以满足导引头全部测试指标的需求。
Based on embedded system.as core,the designing of a testing platform for seeker is proposed.Through generalizing the testing requirements,the adapting interfaces of data acquisition,storage,transmission and displaying are devised reasonably.The dual core structure of ARM9 and FPGA is applied in the hardware design,and the software adopts embedded Linux operating system,when multi-thread programming technique is used in application.Practice shows that this platform has the advantage of abundant interfaces,diverse function and flexible scalability,which can meet all the needs of testing task for seeker.
