摘要近年来国家不断的强调经济结构的转型升级，各行各业都已经开始由劳动力密集 型产业向自动高端机械化生产转变过渡。在这一趋势下，渔业水产养殖行业也需要紧 跟发展浪潮。传统水产养殖行业依靠大量人力成本和人工经验得以生产，不仅效率低 下且对进一步的发展有很大限制。因此，需要一套标准、自动、科学、高效的方法设 备对水产养殖业进行升级，以最少的人力、物力成本达到最高效的控制结果，消除传 统养殖行业中存在的弊端。

水面无人艇可以在无人控制的情况下自主规划、自主航行,独自完成环境感知、 目标探测等任务,作为小型的水面平台，可靠、实用、经济。

本文选取的是一种小水线面双体船。该艇型的船在水下有两个下体，通过两个支 柱与水面上的上船体相连。具有甲板面积宽敞、横稳定性能好、耐波性能好等优点。 针对渔业生产养殖过程中对甲板面积、横稳定性能要求高等特点，因此选用小水线面 双体船作为这艘无人艇的艇型。

在具体进行设计的过程中，首先是对船型参数的设计。这里笔者选用的是母型船 法，对母型船进行缩放，并且适当优化。之后绘制出船体型线图，设计出上建的方案。

其次是对船用设备的选择。根据无人艇的大小、吃水、航速、工作任务、功能等， 选择无人艇的主机、舵、轴系、控制系统、功能系统等。

再次是手工制作中间试验无人艇。针对无人艇的设计与选材，手工制作出一艘精 度满足要求的中间试验艇。

最后是对制作出的无人艇进行一系列的基础性试验。对试验的结果进行分析，绘 制出自由横摇、纵摇衰减曲线，并且主要通过系统辨识处理找到合适的数学模型。

Abstract In recent years, the state has continuously stressed the transformation and upgrading of economic structure, all walks of life have begun by the labor-intensive industries to automatic high-end mechanized production transition。 In this trend, the fishery aquaculture industry also needs to keep up with the wave of development。 Traditional aquaculture industries rely on a large number of labor costs and artificial experience to produce, not only inefficient and further development of the restrictions。 Therefore, the need for a standard, automatic, scientific and efficient method of equipment to upgrade the aquaculture industry, with minimal human and material costs to achieve the most efficient control results, to eliminate the traditional aquaculture industry in the drawbacks。

The surface of the unmanned boat can be in the case of uncontrolled self-planning, autonomous navigation, alone to complete the environmental perception, target detection and other tasks, as a small surface platform, reliable, practical and economical。

This paper chooses a small waterplane surface catamaran。 The boat of  the boat has two lower bodies underwater, connected by two pillars to the upper hull on the water。 With the deck area is spacious, stable and stable performance, good anti-wave performance advantages。 In view of the fishery production and aquaculture process on the deck area, horizontal stability performance requirements, so the selection of small waterplane surface catamaran as the ship without boat。

In the specific design process, the first is the design of the ship parameters。 Here I choose the mother boat law, the mother of the boat to zoom, and the appropriate optimization。 After drawing the hull line diagram, the design of the program。

Followed by the choice of marine equipment。 According to the size of unmanned boats, draft, speed, work tasks, functions, etc。select unmanned host, rudder, shaft, control system, functional system。
