【摘要】 随着计算机技术、通信技术、网络技术的发展,现代化船舶也向自动化和数字化技术的方向快速发展。机舱集中监控系统从早期的模拟式到数字式、分布式,现在已经逐步形成以网络集成自动化系统为主体的网络型结构。这为船舶适应日益严格的安全要求和高度自动化奠定了基础,同时也给船舶机舱自动化的发展带来一次飞跃。本文首先对几种现场总线和局域网各自的功能和特点进行深入的介绍,对机舱监测报警系统的各种功能:报警设定、报警闭锁、延伸报警、报警延时等进行了深入的分析研究。根据机舱监控系统的功能结构和发展趋势,设计了由MCGS组态软件、西门子300的PLC、PROFIBUS现场总线以及以太局域网构成的船舶集中监控系统。先对系统进行硬件设计,然后在软件STEP 7环境中和MCGS平台下实现底层PLC子站对船舶机舱内数据的采集、控制和报警功能,PLC子站与上位机的数据通信以及整个系统监控画面所实现的各项功能的软件设计和仿真。设计的船舶机舱集中监控系统紧密结合现代化船舶发展的趋势,实现了船舶机舱的网络化监控和全船数据资源共享,从而能最大程度地提高船舶航行的安全性、可靠性和经济性。经过对系统的功能测试证明,本文设计的船舶机舱集中监控系统适合应用于目前的大部分船舶,是一种可靠实用的监控系统。更多还原

【Abstract】 With the development of computer, communication and network, modern ships have also developed quickly in automation and digital technology aspect. From early analogical to digital, distributed and now the centralized monitor system of ship’s engine room has formed network structure gradually whose main body is network integrated automation system. It is a basement for the gradually strict safement order and highly automation of ships, it also can bring a great leap to the development of automation of the engine room.The article first gave detailed introduction about the functions and characters of several fieldbus and LAN and gave deep analysis about diversified functions of the monitor and alarm system of the engine room, including: enachment, removal, extending, delay and so on. According to the function, structure and developmental trend , designed the centralized monitor system of ship which composed by MCGS configuration software, Simense PLC 300, PROFIBUS and Ethernet. After designing the hardware, using STEP 7 and MCGS to realize PLC sub stations’ function of data collection, control and alarm, the communication between PLC sub stations and epigyny machine and software designing and emluation of every function of the monitor interface.The centrliazed monitor system of engine room combines with the trend of modern ships’ development closely, realizing the engine room’s network monitor and data resouce sharing of the whole ship, thus it can promote the safety, reliability and economic quality to the great extent. After testing the function of the whole system, the centrliazed monitor system of ship’s engine room in this article is suitable for being applied in most actual ships, it’s a realiable and useful monitoring system.更多还原
