The Display Of WBIS-I Wrist Watch Image Sonar System Based On FPGA

It is of great significance for divers to carry out underwater salvage,positioning and surveying underwater works.But it is very complicated to achieve the process.Except the diver himself working underwater,land staff need to work together to complete the underwater operations.At present,traditional sonar systems are bulky,cumbersome and inflexible,besides operation is also complex.These conventional sonars are normally operated under the robot underwater,assembled on large ships,or worn on a diver's helmet for underwater salvage and detection.With the development of science and technology,according to the application background,different occasions,functions and other needs,customers need to display the sonar image of the video glasses worn on the wrist to use,obviously the traditional sonar equipment can not meet the demand.In order to solve the above problems to deal with more complex environments,based on existing laboratory TKIS-I helmet type color image sonar system and combined with MIPI interface with high resolution TFT-LCD,A WBIS-1 wrist watch image sonar display system based on FPGA is developed in this paper.In this paper,the design of the wrist watch image sonar display system,the author of the main work are:the wrist watch image sonar display system needs analysis,performance indicators,the overall program design,hardware circuit design,SOPC system construction and generation,the design of software,hardware and software debugging and experimental verification.The contents of this paper are:1.The wrist watch image sonar display system has carried on the demand analysis,to determine the performance indicators needed and finally the image sonar display system to do the overall design.2.Combined with the wrist watch image sonar display system overall program design.Firstly,the hardware circuit is designed.The hardware circuit includes the design of the minimum system of FPGA,the design of serial circuit,the design of LCD backlight voltage circuit,the design of RGB to MIPI module circuit and the design of MIPI interface circuit.Secondly,the schematic of each function module is drawn.Finally,the PCB circuit board is designed.3.The LCD controller IP core package and build the SOPC system,and the function of the module parameters set out in detail.4.The wrist watch image sonar display system software was designed.The design of the software part mainly includes six main function modules:the main program,SSD2828 driver,serial port program,image sonar fan sweep,pseudo color coding and range display software design,according to the functional requirements of each function module for the flow chart design and finally according to the design of a good flow chart to achieve the program.5.The hardware and software designed for this article were debugged.Finally,the experimental results are analyzed.Finally,through the experiment to verify the display of WBIS-I wrist watch image sonar system based on FPGA is feasibility and each function module is reasonable.According to the application background,different occasions,functions and many other needs,it can meet the customer needs.
