摘　　要：随着武器装备维修性要求的提高,武器装备的数据处理系统显得越来越重要。为了增强数据处理能力,提高处理速度,将LabWindows/CVI软件开发平台和ARM微处理器数据采集系统相结合,设计了嵌入式测试数据处理系统。通过巴特沃斯滤波、快速傅里叶变换(FFTf,ast Fourier transform)等数据处理功能,得到测试数据的特征参数,从而为装备使用和维修人员提供技术保障方面的帮助。通过仿真与试验表明,此数据处理系统具有调试方便、界面友好、可扩展和处理速度快等优点,是一种可广泛应用的数据处理系统。With the increase of the requirements of weapon maintenance, the data processing system of weapon has become increasingly important. In order to enhance the capability of the data processing and improve the speed, combining the LabWindows/CVI software development platform with the ARM microprocessor data ac- quisition system, an embedded test data processing system has been designed. Using Butterworth filter, fast Fou- rier transform（FFT） and other data processing functions, characteristic parameters of the test data are obtained, then technical assistance to the users and maintenance workers is provided. The simulations and experiments show that the data processing system, which can be widely applied, has many advantages, such as debugging easily, a friendly interface, scalable and a fast processing speed, etc.
