【摘要】：船舶机舱监测报警系统作为自动化无人机舱的核心部分,对于船舶的安全性和可靠性起着非常重要的作用,也是衡量船舶先进程度的重要标志之一,具有重要的研究意义。本文对比分析了单元组合式、微机控制式以及网络式三种不同类型的机舱监测报警系统,基于上述分析确定了以可编程逻辑控制器PLC为核心控制单元的设计方案,并根据某在建船舶相关资料,设计了一套满足于应用需求的机舱监测报警系统。本文分析对比了国内外不同类型的机舱监测报警系统的网络结构与控制方式,并依据中国船级社对该系统的规范要求,选择了一种适合于中小型船舶的网络结构和监测报警控制方式,从而确立整个监测报警系统的设计方案,根据上述设计方案绘制了该系统的网络结构图和监测点明细表。根据确立的设计方案,以西门子S7-300PLC作为核心控制单元,运用STEP7对下位机PLC进行程序设计,实现下位机PLC的数据采集处理及各项控制功能。此外,采用西门子组态软件WinCC设计了上位机的人机交互界面,通过全局脚本的编写来实现界面的各项功能。通过S7-PLCSIM仿真软件对PLC和WinCC进行了联合仿真调试,验证PLC程序的正确性以及人机交互界面的功能性。最后,本文通过SOL Server建立了机舱监测报警数据库,搭建了机舱监测报警数据服务器,方便整个系统数据的查看及实时共享。通过仿真验证,本文设计的船舶机舱监测报警系统满足机舱监测报警系统各项功能要求,符合新的船舶机舱监测报警系统的发展要求。
[Abstract]:As the core part of the automatic unmanned engine room, the ship engine room monitoring and warning system plays a very important role in the safety and reliability of the ship, and it is also one of the important signs to measure the advanced degree of the ship, which has important research significance. This paper compares and analyzes three different types of engine room monitoring and alarm systems: unit combination, microcomputer control and network. Based on the above analysis, the design scheme of PLC as the core control unit is determined. According to the related data of a ship under construction, a monitoring and alarming system for engine room is designed to meet the needs of application. This paper analyzes and compares the network structure and control mode of different types of engine room monitoring and alarm system at home and abroad, and according to the specification requirements of China Classification Society for this system, A kind of network structure and monitoring alarm control mode suitable for small and medium sized ships are selected, so as to establish the design scheme of the whole monitoring and alarm system. According to the above design scheme, the network structure diagram of the system and the detailed list of monitoring points are drawn. According to the established design scheme, Siemens S7-300PLC is used as the core control unit, and STEP7 is used to program the lower computer PLC, which realizes the data acquisition and processing of the lower computer PLC and various control functions. In addition, the man-machine interface of upper computer is designed by using Siemens configuration software WinCC, and the functions of interface are realized by compiling the global script. The PLC and WinCC are simulated and debugged by the S7-PLCSIM simulation software to verify the correctness of the PLC program and the functionality of the man-machine interface. Finally, the database of engine room monitoring and alarm is established through SOL Server, and the engine room monitoring and alarming data server is built, which is convenient for the data viewing and real-time sharing of the whole system. The simulation results show that the marine engine room monitoring and alarm system designed in this paper can meet the functional requirements of the engine room monitoring and alarm system and meet the development requirements of the new ship engine room monitoring and alarm system.
