摘 要
动力定位系统(Dynamic Positioning System)是船舶在不借助锚泊系统的情况下根据环境测量系统,检测出船舶实际位置和目标位置的偏差,依靠自身动力系统,在控制系统的控制下抵御外界风、浪、流的干扰,使其保持预定的航向航速或者固定在要求的海平面上。动力定位是实现耙吸挖泥船精确疏浚定位、提升疏浚档次、提高疏浚效益的一种重要保障。
论文针对实际工程项目,以中交天津航道局建造的“通程号”18000方耙吸式挖泥船动力定位系统作为研究课题。根据耙吸挖泥船动力定位系统的要求,对动力定位系统的实施方案及硬软件设计进行了探讨与研究。论文具有明确的工程应用背景和较高的实用价值,其主要工作如下:
首先以“通程号”为应用背景,分析了耙吸挖泥船集成疏浚控制系统。对动力定位系统的基本原理、结构组成及基本功能进行了介绍。针对耙吸挖泥船复杂的工作流程及疏浚过程的阶段性,提出了耙吸挖泥船动力定位系统的八大功能。
其次在动力定位系统结构和功能的基础上,构建整个系统的硬件框架和网络结构,并对动力定位系统中的环境测量信号进行分析描述,最后对动力系统与各个执行机构、疏浚控制系统以及功率管理系统接口信号进行分析。
然后以“通程号”为应用对象,具体说明了该船的复合驱动方式及全船电网模式,接着在介绍耙吸挖泥船功率管理系统的基础上,设计了其功率管理系统的基本框架,并结合动力定位系统提出了低压电站的自动管理以及艏侧推的管理方法。
最后在动力定位系统软件部分介绍了如何利用OPC客户端采集PLC系统的数据以及串口信号的采集方法和解析协议。另外也针对实际工程提出了动力定位系统中执行机构的控制逻辑和要求。
论文的主要研究成果已在该耙吸挖泥船上进行了应用,取得了很好的实船效果,获得了航道局、公司和导师的肯定与好评。

Abstract
Dynamic positioning system is that ship measure the error of ship's actual position and target location according to the environment measure system without the aid of the ship mooring system, and resist the external signal disturbance under the function of the control system by own power system to keep the required speed and the scheduled course or fixed sea level. Dynamic positioning is an important guarantee for precise dredging orientation, ascending dredging class, improving dredging benefits of a suction hoper dredger .
This thesis focuses on the dynamic positioning system of the 18,000 squares trailing suction hopper dredger named “TONGCHENGHAO”, constructed by cccc-Tianjin Dredging. The implementation plan, hardware and software design of dynamic positioning system were studied according to the system requirement. The applied background of this thesis is very clearly, and the practical value is very high. The main task of this thesis is as follows.
Firstly, integration hopper dredging control system of Trailing suction hopper dredger is analysed based on the “TONGCHENGHAO”. Then the principle of dynamic positioning system, composition and functions are introduced. The eight functions of the dredger dynamic positioning system were provided according to the complex work process and dredging process phases of the dredger.
Secondly, the entire system’s hardware and the network are designed based on the structure and function of the dynamic positioning system, and the measurement signal of environment is described. Finally the interface signals between dynamic positioning system and the various implementing agencies, dredging control system, power management system, is analyzed.
Thirdly, according to 18,000 square trailing suction dredger, the power structure of the ship and the ship's power grid configuration mode are detailed, and the ship's power management system is introduced. And then the power management system framework is designed, low-voltage automatic power management, and bow thruster management is proposed combined with the dynamic positioning system.
At last, how to use the OPC client to collect date of PLC and serial signal acquisition methods and analytical protocols are described at dynamic positioning software section. The actuator control logic and requirements is proposed for the dynamic positioning system according to actual project.
The main results of this thesis are used on the “TONGCHENGHAO”. Dynamic positioning system has obtained the enterprise, company and my teacher's high praise because of its perfect performance.
