Fish Detection System Embedded Navigation Software Design

TO afford the functions such as displaying charts , monitoring ships, giving an alarm automatically,displaying fish and the temperature of seafloor, an Embedded Electronic Navigation and fish System is designed and implemented in this dissertation. The system uses a high performance 32-bits embedded processor(Intel PXA255). The embedded Linux is used as its operating system .Also,an embedded GUI is designed . The system is smaller, more stable ,and easier in operations.In chapter 1,the current research status of Electronic Navigation Chart(ENC) and a fish system are described. Also the significance of the research work and the research task are given.In chapter 2, the embedded system, the technology of Electronic Navigation Chart(ENC) and a fish system are discussed.In chapter 3, the whole design of the System is introduced including the hardware system solution, the software system solution and the data stream of system.In chapter 4,the design of map pretreatment software is discussed,including Map_Img module, Map_Indexbfsplit module, SplitMap and Map_Index_afsplit module.In chapter 5, the design of the Embedded software is introduced in detail. The architecture of the embedded software, flow charts and widget design are discussed.The communication module and GUI module of fish server,the software design of chart paint and the design of system window are discussed importantly.In chapter 6, the hardware and software testing is given, including the function testing,the performance and stability testing .In chapter 7, the main research conclusions are summarized. The prospect of further research is also proposed.
