Research And Realization Of The Display-Control Technology In Navigation Terminal Equipments

This dissertation focuses on the navigation system, it mainly researches the embedded display_control technique of different navigation terminals and their uniform modular design. It particularly expatiates the hardware design and software design of the module and discusses the integration method of multiplicate display_control module. The major work is as following:The first part introduces the general situation of Embedded System, Emphasizes the notion, meaning and development of modularization. Moreover discusses the general design of the embedded terminal display-control system.The second part takes measures on the point of modular design, macrocosmically presents the hardware's modular design of the terminal display-control system and expatiates the modular design of each hardware module, mainly including the control module, LCD module and temperature controlling module.The third part analyses the software requirement of terminal display-control system, hereby compartmentalizes the software function modules. Mainly discusses the software design of serial communication module. Analyses how to design dendriform menu , presents some criteria to the design for Human-Computer Interface and the Integration-developping environment(IDE) of AVR Microcontroller.The fourth aims at the implement of engineering. Discusses the integration method of multiplicate display-control module and presents some terminal display-control systems already achieved in engineering practice. Show the testing method.
