Abstract
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.关键词
