摘　　要：为提高稳定平台的性能,针对平台中各种类型陀螺高速度、高精度、宽动态范围的设计指标要求,研制了一种通用数据采集处理系统。在详细分析动力调谐、光纤和微机械陀螺典型型号性能参数指标的基础上,提出了系统的设计指标要求,选择8通道24位∑-?高精度模数转换器ADS1278和32位数字信号处理器TMS320F2812,设计实现系统的硬件电路,编写了相关的软件程序,并进行了实验验证。实验表明:系统的转台测试数据与陀螺出厂标定的性能参数之间,测量误差小于1%,完全满足稳定平台中陀螺的应用要求。In order to improve the performance of stabilized platform,research and develop a data acquisition and processing system for various gyros in stabilized platform to achieve high speed,high accuracy and wide dynamic range.The system design requirements are proposed based on detail analysis of several typical gyros,such as dynamically tuned gyro（DTG）,fiber optical gyro（FOG） and MEMS gyro.In the meanwhile,8 channels and 24 bits∑-Δ analog-digital converter ADS1278 and 32bits digital signal processor TMS320F2812 are chosen to design and realization the hardware circuits,and also the software program is compiled.The experiment result shows that the errors of data acquisition and processing system are less than 1%,which can meet the requirements of stabilized platform gyros.
