【摘要】：自上世纪九十年代，油液监测技术被用于装甲装备的技术状态监控，标志着装甲装备的维修方式从传统的预防维修向着视情维修转变。该项技术的应用，有效减少了装备故障停机损失，提高了设备完好率水平，降低了维修成本，，为部队作战和训练任务的顺利完成提供了保障。本文结合北京特种车辆研究所十二五预研项目——“变速传动系统故障监测关键技术研究”，研究了基于油液监测技术的磨损状态评定系统的开发技术，搭建了基于MFC（Microsoft Foundation Classes，微软基础类库）单文档模式的系统框架，并探讨了系统实现的关键技术。本文的主要研究工作为：（1）分析了磨损状态评定的相关算法，以Visual C++6.0为开发平台，开发了一套磨损状态评定系统。（2）利用Microsoft SQL Server2000创建了该评定系统数据库，操作简单、方便。使用者只需要在SQL Server企业管理器组件中创建名称为ExpertSystem的数据库，其创建过程与新建指定名称的文件夹一样容易。数据库中数据表格的创建及维护工作将通过ADO（AxtiveX Data Objects，ActiveX数据对象）技术自动完成。（3）与传统的登录窗口相比，除了帐号和密码之外，还设置了三种登录身份，分别为：管理员、专家和用户。以不同的身份登录，具有不同的使用权限。（4）在系统开发过程中，使用以下混合编程技术实现系统预定功能——利用VC与Excel混合编程读取SPSS因子分析结果、利用VC与MATCOM混合编程获取基于投影寻踪的最佳投影向量、利用VC调用MATLAB Engine库计算基于最大熵的评定阈值及利用VC与Word混合编程实现评定规则制定报告和评定结果报告的输出。系统具有界面友好、操作简单、执行效率高等特点。同时，系统的成功研制为后续故障诊断功能的实现奠定了基础。
[Abstract]:Since -10s, oil monitoring technology has been used to monitor the technical status of armored equipment, marking a shift from traditional preventive maintenance to situational maintenance. It can effectively reduce the equipment downtime loss, improve the level of the equipment integrity rate, reduce the maintenance cost, and provide the guarantee for the successful completion of the combat and training tasks of the troops. In this paper, the development technology of wear condition assessment system based on oil monitoring technology is studied in combination with Beijing Special vehicle Research Institute's 12th Five-Year Plan Research Project, "Research on key Technologies for Fault Monitoring of Transmission system with variable Speed". The system framework of single document schema based on MFC(Microsoft Foundation Classes (Microsoft basic Class Library) is built, and the key technology of system implementation is discussed. The main research work of this paper is as follows:. 1) the related algorithms of wear state evaluation are analyzed, and a set of wear state evaluation system is developed on the platform of Visual C 6.0. The database of the evaluation system is created by using Microsoft SQL Server2000, which is simple and convenient. The user only needs to create the database named ExpertSystem in the SQL Server enterprise manager component. The creation process is as easy as creating a new folder with a specified name. The creation and maintenance of data tables in the database will be done automatically through ADO(AxtiveX Data objects ActiveX data object technology. Compared with the traditional login window, in addition to the account number and password, there are also three login identities: administrator, expert and user. 4) in the process of system development, the following hybrid programming techniques are used to realize the predefined function of the system: the mixed programming of VC and Excel is used to read the results of SPSS factor analysis, and the best projection vector based on projection pursuit is obtained by using the mixed programming of VC and MATCOM. The evaluation threshold based on maximum entropy is calculated by calling MATLAB Engine library by VC and the output of evaluation rule and evaluation result report is realized by mixed programming of VC and Word. The system has the advantages of friendly interface, simple operation and high execution efficiency. At the same time, the successful development of the system lays a foundation for the realization of the function of subsequent fault diagnosis.
