Data Collecting System Of Ship Based On USB And CAN Bus Technologies

With the development of computer, communication and control technologies, the era of information has already come. During the 21st century, who can grasp more useful information and who will drive the advancement and development of the whole world. So we need study and work hard always. At the same time, we also need go ahead with the age and contribute our power for great country's boom and mightiness.As we all know, bus technology plays very important role during the information exchange of computers. Especially in the recent years, many new types of bus technologies came into being with the application. These new technologies' appearance made the information exchange process more quicker and lighter. Whereas, USB and CAN bus technologies are typical representations of these new types of bus technologies. So we chose these two kinds of bus technologies as the study topic.During this thesis, author emphatically discussed USB and CAN bus technologies' basic knowledge and application through the study for data collecting system of ship based on USB and CAN bus technologies. Simultaneously, author made this thesis into three phases to study. Firstly, author researched the data collecting system based on USB technology. Secondly, author researched the intelligence collecting node based on CAN bus technology. Thirdly, author made a synthetic study for USB and CAN bus technology.During the study process, especially when we study USB technology, the software programs included firmware program, drivers and application. In order to introduce these contents distinctly, author discussed these contents respectively and detailedly. At the same time, author gave out the hardware circuits' principle diagrams and the program's code partly during the appendix.
