摘要
航天CCD相机控制器的研制具有一定的复杂性,为了提高系统的安全性和可靠性,符合航天系统的可继承性要求,降低系统研制风险,提出了一种嵌入式航天CCD相机控制器研制模板。该模板采用了嵌入式的研制手段,使用自顶向下的研制方法,使得相机控制器的各个研制阶段都能从系统整体结构角度开展研制工作。将该模板应用到某型号的航天CCD相机控制器的研制过程中指导各个阶段的研制工作,不但可以较好地与航天系统研制过程结合,降低了可颠覆性风险的发生,而且取得了较高程度的嵌入式特性。
The aerospace CCD camera controller system has its complicacy to be designed.In order to improve the system＇s safety and reliability,accord with the inheritability principle of aerospace electronic systems,and decrease the risk of the design,an iterative design method is proposed.The embedded approach and top-down design method are adopted in the iterative process.All the steps of the camera controller are designed as viewed from the ensemble structure.A high-performance controller system for embedded aerospace CCD cameras was achieved.The serious subversive risks were avoided in the early design stage by the iterative process.
