摘 要

船舶发电机是船舶电力系统的最重要组成部分，只有当船舶发电机处于正常工作的状态下，船舶才能保持正常的航行状态。一旦船舶发电机出现故障却没来的急进行维修时，全船极有可能出现失电的情况，因此发电机出现故障需要进行及时的维修。否则不仅极有可能会造成很大的经济损失甚至会损伤船舶且造成人员的伤亡。因此我们对船用发电机的健康管理与智能维护进行研究可以极大程度的帮助解决这一问题，是有着重大意义的。目前来看，随着科技的迅速发展，船用发电机的各方向研究也越来越先进，但是对于船用发电机的智能维护与健康管理方面我们还是需要进一步的发展。

本文主要的任务是对船用发电机进行健康管理个智能维护的智能运维进行研究和设计，最终设计出一个通过动态链接库搭建出来的包含五个不同数据库的智能运维管理数据库。本文主要完成了以下的工作：

（1）了解了国内外的船用发电机发展过程和有关船用发电机的故障诊断技术的发展，并确立了本文的研究的主要内容。

（2）了解和学习了船用发电机的具体构造，并且分析其工作原理，通过发电机的构造组成对各个部件的保养与维修进行分析。分析和研究了有关船用发电机的不同故障模式，并且针对船用发电机的日常保养计划措施和维修计划进行了详细的研究。

（3）通过对Access数据库，VC 软件，DAO接口等技术的学习和使用，联合构建出了一个包含人员管理，设备管理，备品备件管理，维修管理和保养计划管理的运维管理数据库。首先建立出了五个模块的数据表单，并且将表单进行详细的关联。接着我们通过软件的使用搭建出了有关船用发电机的智能运维管理数据库并且通过程序逻辑框图对该数据库的添加，删除，修改，查询功能进行分析。

（4）首先将构建出的运维管理数据库策略进行关联与分析，并且将五个数据模块的数据进行表单的建立与入库。其次通过对船用发电机的具体案例分析，研究了我们所构建的管理数据库中五个数据库之间在不同工况下的联系。当发电机处于不同的工况下，运维管理系统则会通过联系不同的模块的数据对该工况进行处理。

本文最终通过运用Visual C 程序和DAO接口等技术最终建立了建一个包含不同数据库模块的智能运维管理数据库，该数据库可以将不同的发电机健康管理因素进行联合和统计本研究所建立的运维管理系统基本实现了：当发电机运行监测系统为运维管理系统提供发电机运行状态的具体数据参数时，智能运维系统能够依据具体情景选择最符合的一种运行策略并依据此策略自动呈现表单。这为船舶轮机员的日常工作提供了数据支持，从而保障船用发电机的安全操作。

Abstract

The ship generator is the most important part of the ship's power system. Only when the ship generator is in the normal working condition, the ship can maintain the normal navigation state. Once the ship generator failure did not come to the emergency repair, the ship is likely to be out of power situation, so the generator failure requires timely maintenance. Otherwise it is not only very likely to cause great economic losses and even damage the ship and cause casualties. Therefore, we study the health management and intelligent maintenance of marine generators can greatly help solve this problem, it is of great significance.

The main task of this paper is to study and design the intelligent operation and maintenance of intelligent maintenance of marine generators. Finally, we design an intelligent operation and management database containing five different databases through dynamic link library：

(1)The development process of marine generators at home and abroad and the development of fault diagnosis technology for marine generators are studied, and the main contents of this paper are established.

(2) Understand and study the specific structure of marine generators, and analyze the working principle, through the composition of the generator components of the maintenance and maintenance of the analysis. The different failure modes of marine generators are analyzed and studied, and the routine maintenance plan and maintenance plan of marine generators are studied in detail.

(3) Through the study of Access database, VC software, DAO interface and other technologies, a management and management database containing personnel management, equipment management, spare parts management, maintenance management and maintenance plan management is jointly constructed. First set up five modules of the data form, and the form for a detailed association. Then we use the software to build out the intelligent operation and maintenance management database of marine generators and through the program logic block diagram of the database to add, delete, modify, query function analysis.

(4) First of all, the operation and maintenance management database strategy is analyzed and analyzed, and the data of five data modules are set up and stored. Secondly, through the analysis of the specific cases of marine generators, we study the relationship between the five databases in the management database and the different working conditions. When the generator is in different operating conditions, the operation and maintenance management system will be through the contact of different modules of the data to deal with the conditions.

In this paper, through the use of Visual C program and DAO interface technology, such as the final establishment of a database containing different modules of the intelligent operation and maintenance management database, the database can be different generator health management factors combined and statistical study of the establishment of the operation and maintenance The management system basically realized that when the generator running monitoring system provides the specific data parameters of the generator running status for the operation and maintenance management system, the intelligent operation and maintenance system can select the most suitable operation strategy according to the specific situation and automatically according to the strategy Form. This provides data support for the day-to-day work of marine engineers, thus ensuring safe operation of marine generators.
