基于TSC695F的高可靠航天相机控制器设计

摘要

As the traditional camera controller cannot satisfy the requirement of aerospace camera for further task and higher reliability, this paper put forward a new design method for high reliability aerospace camera controller which uses TSC695F as kernel CPU with the assistant of FPGA for extended function and interface based on a practical project. The composing of the system has been illuminated, the software and hardware design has been given out at the same time. The high reliability aerospace camera controller has been tested with the simulation orbit test platform.The results show that the camera controller mentioned in this paper not only predigest the hardware design but also optimize the organization of software image. The controller works with high stabilization and reliability, it provides a new idea for new-style aerospace camera controller design.%针对传统相机控制器已无法满足航天相机更多的任务需求和更高的可靠性要求,本文根据某实际型号项目应用背景提出了一种以TSC695F为核心处理器,FPGA辅助其进行功能及外围接口扩展的新型高可靠航天相机控制器设计方案,并详细阐述了系统的组成和软硬件设计.结合航天光学相机模拟在轨飞行测试平台进行的大量测试,结果表明,本相机控制器在硬件设计简化和程序映像组织优化的同时工作稳定、可靠,为新一代航天相机控制器设计提供了新的思路.
