摘　　要：性能测试是航空数码相机生产和装备过程中非常重要的一个环节,对其的使用评估有着不可替代的作用;以三星的ARM9处理器S3C2440A和Windows CE操作系统为核心,结合现代接口技术,介绍了某型航空数码相机地面检测系统总体设计思路和系统构成,重点分析了主体电路的硬件设计和Windows CE系统下相关软件的编写;通过BCD拨码器,串口电路,处理器和LED数码管组成模块模拟飞行状态输入和显示,编写相关软件完成了图像数据的格式转变和实时显示;实际使用结果显示,该检测系统运行稳定可靠,具有一定的实用性和参考价值。Performance testing is one of very important procedures in the process of aviation digital camera＇ s production and equipment. It plays the irreplaceable role in performance assessment. The overall design and system structure of a camera testing system based on s3c2440 and Windows CE operating system is introduced, especially analysed how to design the main circuits with hardware and write software in WinCE system. It can imitate the input of flight state and display the results with the module which is composed of BCD dial switch, serial port circuitry, processor and LED digital tube. It completed the transformation of image format and real-time display by writing some special software. The results of application show that the testing system is stable and reliable , It has a certain relevance and reference value.
