【摘要】：随着船舶逐渐向大型化方向发展、航道或港口的不断扩建,需要利用大型的船舶操纵模拟器在特定水域进行通航安全评估试验。现有的评估试验都是采用人工操舵方式,这对操船技术提出了更高的要求,但即使是船艺再好的船员也不能保证绝对的成功率,这在一定程度上增加了主观因素对评估结果的不利影响,同时增加了操船者的工作量,因而设计实现基于自动控制的船舶航行安全评估将会很好的解决上述问题。海船船员理论知识考试目前已经实现无纸化,实操评估仍然是基于大型的船舶操纵模拟器获得操船相关数据,由评估员手动进行评估,这在一定程度上增加了评估员主观因素对评估结果的不利影响,同时增加了评估员的工作量,因而实现船舶操纵安全的自动评估将会成为未来考试改革的必然趋势。为解决上述问题,本文以计算机仿真技术为背景,利用Visual C++面向对象程序设计语言进行编程,采用三自由度的MMG(Maneuvering Mathematical Model Group)船舶运动数学模型,基于标准电子海图模拟海上真实情况,开发一种运行在PC上的船舶航行安全自动评估系统,并详细说明了系统的构架、功能、评估原理设计。实现两项主要功能:一、把自动控制方法应用到通航评估试验中,来代替传统上的人工操舵模式进行基于自动控制的通航安全评估;二、对驾驶员的实操水平进行自动评估。大量评估实验结果表明:利用本系统进行评估,效果良好,减少了人工操作模式下主观因素大、操船人员工作量大的缺点;减少了评估员根据经验进行评估的随意性,大幅度减少评估员的工作量;同时顺应船舶操纵模拟器向小型化发展的趋势,'提高了评估系统的普及率。本文仅仅作为船舶评估领域的一种补充,希望能对船舶航行安全智能评估领域的发展提供一定参考价值。
[Abstract]:With the development of the ship towards the large scale and the continuous expansion of the channel or port, it is necessary to use the large ship maneuvering simulator to carry out navigable safety assessment test in the specific waters. The existing evaluation tests are all conducted by manual steering, which puts forward higher requirements for ship handling techniques, but even the crew members who are of great skill cannot guarantee an absolute success rate. To a certain extent, it increases the adverse effect of subjective factors on the evaluation results and increases the workload of ship operators. Therefore, the design and implementation of ship navigation safety assessment based on automatic control will solve the above problems well. At present, the examination of seafarers' theoretical knowledge has been paperless, and the actual evaluation is still based on the large-scale ship handling simulator to obtain the ship operation data, which is evaluated manually by the appraiser. To a certain extent, the subjective factors of assessors have an adverse effect on the evaluation results, and at the same time increase the workload of assessors. Therefore, the realization of automatic evaluation of ship handling safety will become an inevitable trend in the future examination reform. In order to solve the above problems, this paper takes the computer simulation technology as the background, uses Visual C object-oriented programming language to program, and adopts the three-degree-of-freedom mathematical model of ship motion of MMG(Maneuvering Mathematical Model Group. Based on the standard electronic chart to simulate the real situation at sea, an automatic evaluation system for ship navigation safety running on PC is developed. The structure, function and design of evaluation principle of the system are described in detail. Two main functions are realized: first, the automatic control method is applied to the navigation evaluation test, instead of the traditional manual steering mode, the navigation safety evaluation based on automatic control is carried out; second, the actual operation level of the pilot is automatically evaluated. The results of a large number of evaluation experiments show that the effectiveness of the system is good, and the disadvantages of large subjective factors and heavy workload in manual operation mode are reduced, and the randomness of evaluation by appraisers based on experience is reduced. The workload of assessors is greatly reduced, and the popularization rate of evaluation system is increased according to the trend of miniaturization of ship handling simulators. As a supplement to the field of ship assessment, this paper hopes to provide some reference value for the development of intelligent evaluation of ship navigation safety.
