Design Method And Implement Of Embedded Aerospace Remote Sensing Camera Controller

Nowadays, in the aerospace electronic system safety and reliability area, a series of design criterions have been built to guide the design process. But there are no opposite parts in the system design area to fulfill them. In order to change this condition, in this thesis an embedded object-oriented design process , by which an embedded aerospace remote sensing camera controller is designed to demonstrate the micro design process of the macro aerospace building process, is introduced.This micro process has the following characteristics.Firstly, in this process, UML profiles are created to guide the analysis and design works, which resolves the problem of traceable links between requirements and design elements and improves modeling description accuracy level.Secondly, in this process, a high reliable and safety camera controller structure is achieved by combining all the safety and reliable requirements, which have been included in the aerospace system design criterions and not yet, such as FMEA, FTA, EMC, anti-latching up, IA and AEA.Thirdly, in this process, a software design pattern, which is based on QP(a practical UML statecharts for embedded systems programming platform ), is introduced in details. By this design pattern all the risks, which traditional signal processing oriented pattern must face on, are eliminated. Also by this pattern, the source codes can be generated semi-automatically and visibly. Lastly, in this process, a realtime tracing system is used to trace the running system without interrupting and outputs the readable application and kernel information with fine scaled timestamps, which makes the measurement of system performance much more elaborate with a real-time fashion.
