疏浚作业仿真训练器集中监控报警及优化系统
摘要
本文介绍作者参加武汉理工大学与长江航道局联合承担的国家“九五”重点科技攻关项目“1750m~3／h绞吸式挖泥船新技术装备实验研究及应用”的重要子课题“疏浚作业仿真训练器的研制”中所进行的学习和研究工作。主要包括1750m~3／h绞吸式挖泥船疏浚作业仿真训练器集中监控报警系统的研制；疏浚作业优化操作提示系统的开发；仿真主模型计算机、接口管理计算机、监控计算机之间的数据管理和数据通信等。
疏浚仿真训练器集中监控报警系统以国产1750m~3／h绞吸式挖泥船集中监控报警系统为仿真母型，在大量调查研究基础上，通过对各种监控数据、报警提示适当取舍、扩充，并进行总体规划设计，经过分门别类地编排组织，采用过程图形编辑软件开发了大量生动、形象、直观、交互性强的集中监控报警界面，使之组成脉络分明、层次清晰的有序系统。根据1750m~3／h绞吸式挖泥船吸口处泥浆形成过程的数学模型，通过对计算泥浆比重及体积浓度的方法进行专门研究，采用即时交互方式，按疏浚作业优化操作步骤开发出指导性强的疏浚作业优化操作提示系统。为确保仿真主模型计算机、接口管理计算机、监控计算机之间的实时通信，采取数据集中管理模式对系统大量实时交换数据进行高效管理，对各层次、各部分之间数据通信采用“客户机—服务器模型”，按照TCP／IP协议、应用socket套接字实现局域网数据通信。
集中监控报警系统能较好地仿真母型船集中监控报警系统，为学员提供了全面集中、即时可靠的疏浚数据和工况参数，并根据培训需要在系统中扩充了预警功能。有效地指示学员进行正确操作。疏浚作业优化操作提示系统使疏浚作业仿真训练器更有利于培训与教学，用于培训疏浚专业学生和挖泥船船员掌握先进疏浚方法，达到高效作业目的。多进程、共享内存等计算机应用及仿真技术的综合运用有效提高了系统高效性和实时能力。
This thesis introduces the author's study, work and research, during the period of author participating in the research and development of the first 1750m3/h cutter suction dredger's dredging process training simulator in China. This project is one part of Research and Application of New Technologies and Equipment Project in the 1750m3/h Cutter Suction Dredger, which is one of the Ninth Five-Year State Key Projects and was developed by the joint efforts of Changjiang Waterway Bureau and Wuhan University of Technology. The thesis mainly focuses on the integrative monitoring, alarming and optimized dredging operation system. The data management and communications among the simulation computers are also been developed.
The integrative monitoring and alarming system of the dredging process training simulator takes a "1750m3/h Cutter Suction Dredger" as a model dredger. Based on plenty of investigations and researches, the thesis developed lots of lively, vivid, visual integrative monitor and alarm interfaces with excellent interactive quality by processing graphical edit software in the integrative monitoring and alarming system. The thesis managed to make them to be an ordinal, clear and distinct system, by programming and designing as a whole, arranging and organizing systematically. According as the mathematic model near the inlet of the 1750m3/h cutter suction dredger, by researching the method of calculating the slop's specific gravity and volume concentration, the thesis adopted instant interactive mode and developed the optimized dredging operation guiding and training system, which has outstanding instructional quality. In order to insure the real-time communication among the main simulation model computer, the inte
rface management computer, the monitor computer, dredging process training simulator adopted the integrative data manage mode to handle a mass of the real-time interactive data in the system efficiently. Client-Sever Model, TCP/IP and socket were applied to realize the data's communications among all the layers and parts in the local area network.
The integrative monitoring and alarming system of the dredging process training simulator is good at simulating the same one of the model dredger, offers
the students all kinds of the general and integrative dredging data and the instant and reliable status parameters. The function of forecasting was added in the system to reduce the students' mistakes greatly in term of the training's demand. The optimized dredging operation guiding and training system makes the dredging process training simulator be better at training and teaching. It can help students whose major is dredging and dredger operators get acquainted with dredging process, so that they can get the best production under the different circumstances. Some computer technologies and simulation technologies, such as multi-thread, shared EMS memory and so on, are employed synthetically to improve the efficiency and real-time quality effectively.
