Preliminary Study On The Design And Performance Of New Fishery Auxiliary Unmanned Surface Vessel

The development of modern aquaculture fishery has greatly enriched the dining table of the people and played an important role in ensuring the dietetic diversity and nutrition balance of the people.It has made an indelible contribution to the rapid growth of social economy,but at the same time extensive aquaculture,aquaculture water pollution.A series of problems such as the degradation of water ecological function and the unreasonable utilization of ecological resources have been accompanied,so it is particularly important to develop a composite carrier to serve the fishery and aquaculture industry.The surface unmanned craft is a fully autonomous unmanned ship with autonomous planning,autonomous navigation and autonomous environment perception,as well as a non-autonomous navigation remote control unmanned vessel and built in in accordance with the built in.Semi-autonomous unmanned craft,which is programmed to sail and carry out missions,integrates ship design,artificial intelligence,information processing and motion control,etc.In view of this,two new types of fishery assistant unmanned craft are designed in this paper.The main work and achievement is as follows:First of all,the model selection of the high performance ship form evaluation method based on fuzzy mathematics is carried out,and the preliminary design analysis is carried out.It is determined that the two fishing auxiliary unmanned craft are trimaran and small waterline catamaran.At the same time,the preliminary scheme design of the target unmanned craft is carried out,including the determination of the main scale,the design of the shape line,the appearance design and the general layout design.Secondly,according to the transformation methods of mother ship new fishery auxiliary unmanned demonstration and design and performance analysis based on optimal production function,and the typical middle test craft model,model of propulsion system,installation and debugging of control system and control system of equipment manufacture,development and design,as well as new independent throw food system and other functional modules.At the same time,design a set of intelligent control system based on embedded STM32,and verify the reliability of the system during the test.Finally,the watertight test,floating test,static horizontal test,pitch test and system identification of the unmanned craft are carried out to verify the reliability of the performance of the unmanned craft.Autonomous navigation test according to set track,autonomous throwing function test,water quality real-time monitoring test based on 2.4G wireless transmission module,and other fishery auxiliary function test.The reliability of fishery aided unmanned craft is fully verified.Through the performance and function test of fishery auxiliary unmanned craft,the design indexes were verified.Pilot boat test results show that the design in line with the expectations,for inland lakes and coastal fisheries aquaculture waters patrol,such as water quality monitoring and autonomous throw food and so on a number of auxiliary breeding work,enhance the automation of the fishery farming,for subsequent implementation industrial-grade fisheries aided design and manufacturing of unmanned craft provides the data support.
