摘要
提出了一种空间应用 CCD视频处理器评估测试系统,并应用于工业级视频处理器的航天可靠性筛选中。以现场可编程门阵列 FPGA为控制处理核心,设计并实现了多路模拟 CCD信号发生、视频处理器工作模式控制、通讯及数据采集等功能,详细介绍了系统的功能组成和工作原理。实际完成了集成 40片 CCD视频处理器的单板评估测试系统,该系统已成功应用在工业级视频处理器 XRD98L63的动态筛选试验中,系统工作稳定可靠。在试验条件为 85℃及 192 h加电工作下,对所用同一批次的视频处理器的功能和性能进行了有效测试。试验结果不合格品率为 0,满足单批次筛选不合格品率小于 5%的要求,实现了空间载荷应用中工业级元器件的可靠性筛选。
Abstract
Evaluation and testing system of CCD video processor for space application is proposed, and used in the aerospace reliability screening of industrial grade video processor. By using Field Programmable Gate Array (FPGA) as control processing core, these functions are designed and implemented including multi-channel analog CCD signal generation,the video processor work mode control, communications, data acquisition and etc., The system functional composition and working principle were introduced in detail. Actual evaluation and testing system was completed with integrating the forty CCD video processors in a single board. The system has been successfully applied in the dynamic build-in screening test of industrial grade video processor XRD98L63, and the system is stable and reliable. The test conditions was being maintained at 85℃ and 192 hours power on operation, and the effective test was finished about the function and performance of the video processor used in the same batch. Test result is zero on the nonconforming product rate, satisfying the qualification that single batch screening nonconforming rate is less than 5%. Reliability screening of industrial grade components for the space load applications is implemented.
