【摘要】 嵌入式系统作为一种新兴的监控系统，目前已经在各个领域引起了高度关注。考虑到船舶空间狭小、作业环境恶劣、安全性要求高等特点，用嵌入式系统逐渐代替传统的PLC(可编程逻辑控制器)系统、工控机系统甚至简单的单片机系统已经成为一种趋势，并在船舶领域得到了愈来愈广泛的应用。 本文的研究课题来源于济南某陆军的一个项目，目的在于实现船艇装备保障活动的信息化组织与管理，打造船艇装备保障的数据链，进一步提高船艇技术管理水平和效益。结合此项目，本文作者设计开发了基于Windows CE.NET的船艇动力装置状态监测与分析系统。此系统可实现对该船艇主推进装置中的20／27型柴油机的现场数据采集、数据流图处理以及状态数据的分析预测等。 此动力装置状态监测与分析系统是利用该船艇动力装置热力参数对动力装置的安全可靠性进行监测预测的，采用的监测分析系统为嵌入式系统。热力参数中包含着大量的故障信息，具有外界干扰小、信息质量好和可用性强等特点，有很大的分析应用价值。利用嵌入式系统对船舶动力装置进行监控，由于嵌入式系统体积小、可靠性高、价格经济、实时性能优越、即插即用等特点，正好可以弥补传统船艇监控系统的缺陷，使系统性能大幅度提高。并且，考虑到船上工作人员更换频繁，文化水平参差不齐，必然会带来诸多问题，故采用嵌入式系统实现船艇监控，还有操作简便，直观性好，容易被操作人员接受的优点。 整个系统选用研华公司的ADAM-4018+I／O(Input／Output输入输出)模块和UNO-2050嵌入式控制器硬件实现。并在上述硬件架构基础之上，以经过剪裁定制的Windows CE.NET 4.2嵌入式操作系统为平台，采用Microsoft Visual Studio.NET 2003集成开发环境中的Visual Basic.NET编程工具实现该船艇动力装置监测与分析系统的应用程序编写。在系统数据分析预测方面，以基于时间序列的AR模型预测算法给出系统可靠性预测，从技术上验证了利用此类数据挖掘算法实现船艇动力装置状态预测的可行性和优越性。因此，基于嵌入式技术的监控方式为船艇动力装置状态监测与分析系统的开发提供了一条经济性好、适用性强的新思路。 作者在本文的总结与展望部分，结合开发过程的体会，提出了有待进一步完善的工作。由于作者经验尚浅，所开发的系统必然存在着一些不足，敬请批更多还原

【Abstract】 As an emerging monitoring and control system, the embedded system has being paid highly attention to in various fields. Considering the narrow space, uncomfortable working circumstance and highly security of the ship, it has been a trend to replace traditional monitoring and control system such as the system of PLC, industry computer and even Single Chip Micyoco with embedded system, which will be more and more applied to the naval and ocean field.The research of this paper came from a project of an land forces in Jinan. The purpose is to realize the informational organization and management and set up a data chain of arming safeguard activity for a warship, so that the technical management for the warship can be improved. So the author developed a monitoring and data-analysis system for power plant based on Windows CE.NET. The system can collect information, deal with the data stream and analysis the data of the main power plant.Thermal parameters of the power plant in the ship have much valuable information of engine faults. The monitoring and data-analysis system take advantage of these parameters. What’s more, as embedded system has the specialties of small volume, highly reliability, suitable price, which are what the traditional monitoring and control system lacks, it will improve the system very much. The new system also has an advantage that the operation staff is easy to understand the monitoring process and data analyzing result concerning the education diversity and frequent mobility of the staff.The whole system operated on Advantech ADAM-4018+I/O module and the UNO-2050 embedded controller. Upon this structure, the system is developed mainly by Windows CE.NET 4.2 and Microsoft Visual Studio.NET 2003. As to the data analysis, the AR algorithm based on time series method has given the forecast of system reliability, which has technically proved the feasibility and superiority of the data analysis system for power plant using such data mining technology. So the monitoring and control method based on embedded system is an efficient, convenient and successful way to developing the monitoring and data-analysis system for power plant.In the summary of the paper, the author discussed some parts of the system which更多还原
