摘要
针对航天器动力学环境试验测试的特点,自主研制了以VXI总线为基础的128通道航天器动力学数据采集处理系统。文章介绍了系统的构成和特点,在硬件上采用块传输和同步时钟等技术,在软件上应用面向对象技术及功能模块分层管理的思想。该系统突破了高速同步采样、大容量数据实时传输、并行任务实现等关键技术,并具备一定的扩充空间,可以投入型号研制中使用。
To meet the technical requirements of dynamic environment test of spacecraft, a data acquisition and processing system is developed with 128 channels based on VXI bus. The block transfer mode and synchronous clock are used in its hardware design, and the object oriented method and the hierarchical function module management are used in its software design. The system features the high-speed synchronous sampling, real-time mass data transmission, parallel task realization, and good expandability. The system can be used in dynamic environment testing for spacecraft.
