The Study Of UWA Networks Techniques Based-on VxWorks

What this thesis should finish is the development of the system software for the underwater acoustic networks' node control system under VxWorks. To accomplish the underwater acoustic networks' node control system, the most widely used embedded processor AT91RM9200 and embedded operating system VxWorks are adopted to fulfill the reliability,timeliness and low power.According to the requirement of real timeliness,reliability and low power, the hardware platform is designed to use AT91RM9200 and VxWorks.The research work of the thesis mainly develops a set of embedded software system for the node control system based on embedded processor AT91RM9200 and embedded operating system VxWorks according to their characteristic on condition that ARM,VxWorks and their development method are fully mastered. The main contents are as follows:1,The transportation of VxWorks to ARM is done. Embedded software system based on ARM_VxWorks is developed,which provides a software platform for application.The main content is as follows:(1) The development of BSP: the modify of core files and the development of several drivers(such as timer,interrupt etc).(2) The driver development of peripheral equipments for ARM_VxWorks platform, such as the drivers for series,network and file device.2,Realization of application for the control system of UAN nodes on the completed embedded software platform in order to manage and control the nodes of UAN.Several key techniques of VxWorks and AT91RM9200 are used to study and complete software design for UAN node control system.
