摘要
为了更加合理地制定机载数据存储设备设计方案,根据机载数据存储设备的设计原则、设计规范,以及结合功能性能技术要求制定设计方案。由于采用自顶向下的设计原则,文中总结分析了影响设计方案制定的几个顶层相关项:传输总线、微控单元、存储接口、存储介质、存储格式,并提出以加权评分数学模型的量化方式设计机载数据存储设备。通过逐步细化相关项,对比分析不同形式方案,按照加权评分量化方式的评分准则选择一种基于ARM架构芯片的机载数据存储设备设计模式。文中所设计的机载数据存储设备在某型机综合数据管理系统中得到应用。应用结果表明,该产品设计稳定可靠,能够满足指标要求。基于加权评分量化方式的设计方案合理有效,对机载数据存储设备的设计研制具有参考意义。
In order to develop more reasonable airborne data storage equipment design scheme,a design plan is made according to the design principles,design specifications,functional and technical requirements of airborne data storage equipment.The several top-level related items that affect the formulation of the design scheme:transmission bus,microcontroller unit,storage interface,storage medium and storage format are summarized and analyzed,and a airborne data storage device is designed by means of the quantitative method of weighted scoring mathematical model.The relevant items are refined gradually,and the comparison analysis of the schemes with different forms are conducted,a airborne data storage equipment design mode based on ARM architecture chip is designed according to the scoring criteria based on weighted scoring quantification.The designed airborne data storage device has been applied in a comprehensive data management system for a certain type of aircraft.The application results show that,the design product is stable and reliable,and can meet the requirements of the index.The design scheme based on weighted score quantification is reasonable and effective,and has reference significance for the design and development of airborne data storage equipment.
