摘要水面无人艇是一种能够在海洋环境下自主航行,并完成各种规定任务的小型水面运动平台，由于无人操作，所以它的下放和回收存在一定的困难，本设计主要研究无人艇吊放系统的电气设计，目的是为了成功的下放和接收无人艇。

第一章为绪论，首先对无人艇进行了简单的介绍，讲述了无人艇的功能，研究无人艇吊放装置的重大意义以及国内外在无人艇吊放装置上的研究状况和发展趋势，最后讲述了本次设计的研究内容。51251

第二章为无人艇艇架的工作介绍，是为下面电气原理图的设计进行铺垫，这章中，向大家介绍了无人艇艇架的主视图和侧视图，能让大家对无人艇吊架有个更直观的了解。同时讲解了艇架的工作方式，它的下放流程和回收流程。

第三章为设计的重点，我们需要对无人艇吊放系统的主电路图进行设计，包括液压马达的位置确定，线路连接，启动方式等。然后设计控制电路图，在控制电路图中，我们需要对防摆绞车、主钩波补切换、压差报警的电气连接图进行分析，确定电气原理图中主开关、指示灯、报警器的位置安放，分析控制电路的运行方式。之后着重分析无人艇吊臂装置中传感器的电气连接，吊臂两端的传感器负责无人艇下放和回收时钢丝绳拉力的检测，以便于确定是否要启动波浪补偿，启动波浪补偿后，钢丝绳将恒定的附着一个力，保证无人艇的平衡，在下放或者回收时能不侧翻。接下来将对左右吊点的PLVC连接进行设计，对其和PLVC端子箱的接线进行讲解。接下来设计其他阀体和PLVC端子箱的接线，并分析其原理。

第四章为相关元器件的选型，在电气原理图设计好之后需要对其中涉及的元器件进行计算选择以确定其最终型号。

第五章讲述了操作面板台的设计，以及左右吊点传感器的介绍。

Abstract

Water unmanned craft is a kind of autonomous navigation in Marine environment, and complete the tasks in accordance with a variety of small water sports platform, because there is no operation, so it's decentralized and it is difficult to recycle, and this design is mainly to study unmanned craft sling the electrical design of the system, the goal is to successfully give and receive no boat.

First chapter for the introduction, first of all, no one boat has carried on the simple introduction, tells the story of unmanned craft function, studies the significance of unmanned boat sling the device and in the unmanned craft sling the device at home and abroad research status and development trend, and finally tells the story of the research content of this design.

Chapter two introduce unmanned boat davit work, is for the design of the electrical schematic diagram below for bedding, in this chapter, introduced the main view and lateral view of unmanned boat davit, can get people to no davit has a more intuitive understanding. At the same time explained the davit ways of working, its devolution and recycling processes.

The third chapter is the focus of the design, we need no boat crane system is put on the main circuit diagram design, including determining the position of the hydraulic motor, wiring, startup mode, etc. Design control circuit diagram, and then in the control circuit diagram, we need to prevent winch, main hook wave, differential pressure switch alarm analysis, the electrical connection diagram to determine the electrical schematic diagram of the main switch, indicator light, alarm positioning, analysis of the operation mode control circuit. After analyzed unmanned boat electrical connection of sensors in hoisting device, sensor at the ends of the hanging arm is responsible for the unmanned boat down and recovery of wire rope tension test, in order to determine whether to start the wave compensation, start the wave compensation after the wire rope will be a constant to a force, to ensure no one boat balance, can not rollover when down or recycling. Next PLVC connection to carry on the design of lifting point around, to explain its wiring and PLVC terminal box. The next design other connection body and PLVC terminal box, and analyzes its principle. PLC无人航行器吊放系统电气设计+CAD图纸:http://www.751com.cn/jixie/lunwen_54827.html
