Research Of The Integrated Navigation Embedded Real-Time Database Based On VxWorks

The Integrated Navigation Display & Control Console (INDCC) is an equipment integrated with navigation information receiving, processing, translating and displaying. Real-Time database can record some important related data, which can be inquired abort when it is needed, especially RTDBS can comeback database when software or hardware is error, these characteristics make it important to empolder Real-Time database.Firstly, the paper introduces the background of the project and the significance of the project, expatiates the constitution, the characteristics of VxWorks operation system and the development, the trend of the ERTDB, then simply summarizes the tasks I will do in the project and the expected effects.Secondly, the paper summarizes Embedded Real-Time database system, mainly discusses the characteristics, the primary problems, the primary functions,data model, system structure, system empolder circumstances and running empolder process. the paper also mainly designs Embedded Real-Time database, including collectivity demand, model, EMS memory system structure, empolder circumstance, module layout, system data types and integrated definition.Thirdly, the paper introduces the design and implementation of ERTDB based on the application exploitation platform of VxWorks. The paper discusses dictionary data structure of ERTDB, detailedly designs basic API including running structure of database, system initialization, system close, insert noting, lookup noting, delete noting, amend noting, also discusses the backup and comeback of database through history database.Finally, the paper introduces definition, task, graph empolder tool and the database design of The Integrated Navigation Display & Control Console.
