【摘要】 本文结合作者参加的青岛远洋船员学院机舱监测报警模拟系统的科研工作，在研究了当今流行的几种现场总线的基础上，分析了现场总线系统的结构特点和技术特点，论述了在船舶机舱中采用现场总线技术的优越性，探讨了LONWORKS总线的基本工作原理，提出了基于LONWORKS总线的船舶机舱监测报警模拟系统的构造方案，并对该监测报警模拟系统的组成、功能等进行了比较详细的论述。 在实验室内建立的这套船舶机舱监测报警模拟系统，充分考虑并结合实际船舶机舱监测报警系统的特点，该系统具有良好的用户界面，操作管理方便，工作可靠，符合教学和训练需要，系统在开发过程中，充分利用了目前计算机信息领域的许多最新技术，如现场总线技术、网络技术、数据库技术、NETDDE技术、INTOUCH技术等，使本系统具有以下主要特点： 1．采用了流行的Lon Works现场总线，符合自动化控制系统的发展趋势和典型的现场总线控制系统的体系结构，体现了系统的开放性、分散性和数字通信的特性。 2．系统具有模块化结构，极大地方便了系统的进一步扩展，提高了系统的可靠性。 3．有利于对学员进行信号测量、信号传递、数据显示、报警显示、参数修改、报警闭锁与唤醒、延伸报警以及模拟实验等各方面的实验和训练，提高学员对现代化船舶自动化控制系统的维护和管理能力。 4．监控功能主要根据软件实现，可以方便地增加或修改监控功能，针对具体船舶稍加修改后可适用于对旧船监测报警系统的改造。 5．最大限度地体现了多媒体技术的优势，具有良好的人机交互界面，维护和管理方便。更多还原

【Abstract】 On the basis of study on a couple of prevailing fieldbus,combined with the development of fieldbus-based simulated monitoring system of marine engine room in Qingdao Ocean Shipping Mariners’ College,which the author joins,the design and technical features of fieldbus systems are analyzed,the advantages to adopt fieldbus technology in narine engine room are discussed,the basic operating principle of LonWorks fieidbus is approached,the structural scheme of LonWorks bus-based monitoring and alarming system simulator of marine engine room (MASSMER) is proposed,and the buildup and function thereof are detailedly expounded to some extent.With the characteristics of actual ship-board MASSMER having been duly considered,this lab-based MASSMER has been designed to have friendly interfaces,convenient operation and management,reliable performance and to be in conformity with the requirements of education and training. During the development of this system,a number of up-to-date technologies in the computer information area have been fully employed such as the technology in fieldbus,network,database,NETDDE and InTouch etc. As a result,this system is characterized by the following points:1. LonWorks fieldbus is adopted,which is in conformity with the trend of development of automation control system and with the architecture of typical fieldbus control system,and objectifies the system’s openness,dispersibility and the property of digital communication;2. modular structure is adopted for this system,which is extremely convenient for its further expansion,and improves its reliability;3. experiments and training can be carried out for the benefit of students on this system in the areas of signal measurement,signal transmission,data display,alarm display,modification of parameters,locking and awakening of alarm,extension alarm and simulation tests etc.,which will improve the ability of students in the maintenance and management of modern ship-board automation control system;4. the monitoring functions are realized by means of software,and as a result,may be increased or modified easily. For a specific vessel,therefore,the old monitoring and alarm system on board can be reformed by way of slight modification thereof;5. the advantages of multimedia technology are embodied to the utmost,with friendly human-computer interfaces and convenient maintenance and management.更多还原
