【摘要】：随着国家对绿色能源的大力倡导,天然气在未来的能源构成中所扮演的角色日益重要。LNG(液化天然气)船舶就是用来运输液化天然气的专用船舶,作为LNG码头和消费地的海上运输媒介,LNG船舶的液货操作显得尤为重要。根据国家发展规划,大批的LNG码头会陆续投入建设和运营,亟需大量高素质的LNG船舶操作人员。研发具有自主知识产权的LNG船液货装卸模拟器是解决这一难题的有效捷径,教练员站系统作为模拟器的关键组成部分,其性能对模拟器的培训效果起到至关重要的作用。本研究实现了教练员站系统的部分功能,所做的主要工作有： (1)阅读大量国内外参考文献后,参考从挪威进口的Neptune CHS模拟器,结合本实验室的硬件设备,确定出了LNG船液货装卸模拟器教练员站系统的功能行为需求、性能需求和运行需求。 (2)基于数据流图的方法分析了教练员站系统的数据接口,确定了装卸货模拟训练和特殊情况处置训练的数据交换过程,进而制订了系统的初步流程设计方案；对系统网络通讯过程中涉及到的某些关键技术和重要概念加以解释,为教练员站系统的实现过程打下基础。 (3)充分考虑到教练员站系统界面设计的一般原则和特殊要求,开发了教练员站系统的部分主要控制界面,具有良好的交互性和可拓展性。对教练员站系统的数据库做出分析后,完成了系统数据库的概念结构设计和逻辑结构设计 (4)实现了教练员站对模拟器其他子系统的开关机控制后,考虑到教练员站系统在学员培训过程的不同时期需要传输和接收的信息流有所不同,选取基于TCP/IP协议的Winsock套接字,使用TCP和UDP两种套接字相结合的方法,用Visual Basic开发了教练员站系统与模拟器其他各子系统的网络通信程序,实现了教练员站系统与模拟器其他子系统间的数据传输。
[Abstract]:With the vigorous advocacy of green energy, natural gas plays an increasingly important role in the future energy composition. LNG (liquefied natural gas) ships are special ships used to transport LNG. As the sea transport medium of LNG wharf and consumer, the liquid cargo operation of LNG ship is very important. According to the national development plan, a large number of LNG terminals will be put into construction and operation one after another, which needs a large number of high-quality LNG ship operators. The development of LNG ship cargo handling simulator with independent intellectual property is an effective shortcut to solve this problem. As a key part of the simulator, the performance of coach station system plays an important role in the training effect of the simulator. The main work of this study is as follows: (1) after reading a large number of references at home and abroad, we refer to the Neptune CHS simulator imported from Norway and combine the hardware equipment of our laboratory. The functional behavior requirements, performance requirements and operation requirements of the coach station system of LNG ship cargo handling simulator are determined. (2) based on the method of data flow chart, the data interface of coach station system is analyzed, the data exchange process of loading and unloading simulation training and special case disposal training is determined, and then the preliminary flow design scheme of the system is worked out. Some key technologies and important concepts involved in the network communication process of the system are explained in order to lay a foundation for the implementation of the coach station system. (3) considering the general principles and special requirements of the interface design of coach station system, part of the main control interface of coach station system is developed, which has good interaction and extensibility. After analyzing the database of the coach station system, the conceptual structure design and logic structure design of the system database are completed. (4) after the coach station controls the switch machine of the other subsystems of the simulator, Considering that the coach station system needs to transmit and receive different information flow in different periods of the training process, the Winsock socket based on TCP/IP protocol is selected and the combination of TCP and UDP is used. The network communication program between the coach station system and other subsystems of the simulator is developed with Visual Basic, and the data transmission between the coach station system and other subsystems of the simulator is realized.
