| With the rapid economic develop and the increasing population of the world, theresources that human being consume becomes more and more. Meanwhile, the landresource is also diminishing. In order to survive and develop, human beings begin toexplore oceans. In recent years, offshore oil exploration and offshore aquacultureindustry develop very fast. At the same time, with the development of industry, moreand more sewage water has been discharged into the ocean. Moreover, human beingsexplore and make use of the ocean resources in an immoderate way which also doescertain harm to the marine ecological environment. Therefore, in order to develop andexplore the ocean in the long run, the monitor of the marine environment and theprotection of marine ecological environment are extremely urgent. However, formonitoring and survey of off-shore water and lakes, the use of large-tonnage scientificresearch vessels will be a big waste of man power and material resources. Thus, theinvention of small sized remote unmanned vessels can not only save human power andmaterial resources to a large extent, but also avoid the risk that faces to the researchers.This thesis first determines the overall structure of the small-sized unmannedvessel based on the study of the basic working requirements and key techniques of itand completes the model selecting of the main module which fulfill the function ofinspecting. The small-sized unmanned vessel this thesis designed is based on theembedded ARM shipborne system and ship control system which is based on theembedded ARM. The communication between the two systems is according to ZigBee.Next is the design of the shipborne system and mechanical structure of shipoperating floor, as well as the spatial arrangement. The body of the ship this thesisdesigned adopts catamaran as the carrier of the operation, hardware and each modules.And the twin-propeller is employed. All parts of the ship operation system areassembled inside a portable water-proof safe box.Then the hardware designs of the shipborne system and the operation system ofthe ship operating floor are followed. The thesis also finishes the writing anddebugging of the drive program of each modules and main program of the wholesystem based on the software development environment of KEIL.In the end, the making and assembling of sample small unmanned vessel is finished, followed by a series of experiments, including fundamental function tests,such as forwards, backwards and turn of the ship body manually, reading of the data ofsensor, collecting of battery level, tests of transmission distance, tests of automaticallynavigation, as well as the tests of resistance to electromagnetic interference of thewhole equipment. Therefore, the feasibility of the whole designing scheme is verified. |
