【摘要】：目前,国内LNG接收站的数量增长迅速,为了满足日益增长的LNG接收站用人需求,现在迫切需要培养大批具有高素质的LNG接收站员工及相关专业在校生,而借助操作员仿真培训系统进行培训将是一种有效的新途径。本文以国内某大型LNG接收站为仿真对象开发了一套集操作仿真与设备管理于一体的LNG接收站操作管理仿真教培系统,系统主要由软件和硬件组成。软件部分以Microsoft Visual Studio C#为开发环境,开发了三部分内容：LNG接收站操作仿真系统、LNG接收站操作考核系统、LNG接收站设备管理系统。本文首先利用GDI+图形绘制工具根据简化整理的LNG接收站工艺流程创建设备自定义控件,然后对LNG接收站的LNG储罐、货泵、BOG压缩机、再冷凝器、汽化器等关键设备进行数学建模,接着按照整理的工艺流程布置仿真界面并编写后台逻辑程序,再利用Microsoft SQL对关键设备的工作原理、操作流程、维修保养方法等资料建立数据库。另外,为了让仿真更加贴近实际,硬件部分设计了实物沙盘模型,软件和沙盘模型之间采用PLC进行实时通信。本文最终开发了一套软件和硬件相结合的操作管理仿真培训系统,避免了纯软件模拟过于抽象的弊端。本套仿真教培系统能够让学员亲手上机操作,模拟LNG接收站的大部分工况。仿真系统结合操作考核系统和设备管理系统使用,功能齐全,使用方便,可节省大量的人力、物力和财力。总之,开发这套系统不仅对培训接收站员工及相关专业在校生有价值,还对促进我国LNG接收站快速发展具有深远意义。
[Abstract]:At present, the number of LNG receiving stations in China is growing rapidly. In order to meet the increasing demand for employing LNG receiving stations, there is an urgent need to train a large number of high-quality LNG receiving station staff and relevant major students.The operator simulation training system will be an effective new way.This paper takes a large LNG receiving station in China as a simulation object to develop a LNG receiving station operation management simulation system which is composed of software and hardware.In the software part, the Microsoft Visual Studio C # is used as the development environment, and three parts of Microsoft receiving station operation simulation system are developed, and the Microsoft receiving station operation assessment system and the Microsoft receiving station equipment management system are developed.In this paper, the GDI drawing tool is used to create the custom control of the equipment according to the simplified LNG receiving station process, and then the mathematical model of the LNG storage tank, the cargo pump bog compressor, the condenser, the carburetor and other key equipment of the LNG receiving station is built.Then, the simulation interface is arranged according to the process flow and the backstage logic program is written, and then the database is established by using Microsoft SQL for the working principle, operation flow, maintenance method and other data of the key equipment.In addition, in order to make the simulation more close to the reality, the hardware part designed the physical sand table model, and the real-time communication between the software and the sand table model using PLC.In this paper, a training system of operation management simulation combining software and hardware is developed, which avoids the drawback that pure software simulation is too abstract.This system can be used to simulate most of the LNG receiving station.The simulation system is combined with the operation examination system and the equipment management system. It has complete functions and is convenient to use. It can save a lot of manpower, material resources and financial resources.In a word, the development of this system is of great significance not only to train the receiving station staff and related students, but also to promote the rapid development of LNG receiving station in China.
