【摘要】：隨著工程建設(shè)規(guī)模的擴大以及技術(shù)要求的提高,大型機械設(shè)備在現(xiàn)代工程建設(shè)中所起的作用變得越來越大,汽車起重機便是一種比較典型的工程機械設(shè)備,故對其關(guān)鍵部件健康狀態(tài)的評估是極為重要的。目前在設(shè)備的健康狀態(tài)評估領(lǐng)域中,有針對性的評估模型很少;同時針對整機系統(tǒng)的性能評估與智能維護缺乏遠程控制能力。 為了解決上述問題,本文以QY90V汽車起重機為研究對象,對基于數(shù)據(jù)驅(qū)動的狀態(tài)性能評估理論方法、實驗驗證、技術(shù)集成等方面進行了研究,具體工作包括: 1)針對工程機械裝備健康狀況評判缺乏評估模型,導(dǎo)致無法準確判定設(shè)備健康狀態(tài)的問題,通過研究設(shè)備的性能狀態(tài)描述方法,并綜合設(shè)備信號的特征提取、特征選擇、狀態(tài)分類等理論方法的研究,并依據(jù)OSA-CBM(open system architecture for condition-based maintenance)標準流程開發(fā)出多模式設(shè)備狀態(tài)性能評估模型的獲取系統(tǒng); 2)基于WEB的設(shè)備遠程監(jiān)測診斷平臺開發(fā),通過對WEB-GIS/GPS集成技術(shù)、嵌入式Google Earth /map技術(shù)、面向用戶的Web化服務(wù)技術(shù)的研究,構(gòu)建基于SOA(service-oriented architecture)的遠程監(jiān)測服務(wù)平臺系統(tǒng)框架,為大型機械設(shè)備遠程監(jiān)測與維護系統(tǒng)的開發(fā)提供軟件平臺支撐。在為企業(yè)用戶的實際應(yīng)用提供更大靈活性的同時,可以通過用戶權(quán)限設(shè)置增加用戶平臺系統(tǒng)的安全性。 通過對上述理論方法與技術(shù)應(yīng)用的集成,實現(xiàn)了狀態(tài)性能評估模型生成工具及汽車起重機狀態(tài)遠程監(jiān)控系統(tǒng)的開發(fā)。同時實現(xiàn)了基于Web的遠程服務(wù)系統(tǒng),并以QY90V汽車起重機的主泵軸承系統(tǒng)為應(yīng)用對象,在網(wǎng)絡(luò)的監(jiān)控平臺上進行診斷系統(tǒng)的實際應(yīng)用,實際應(yīng)用的效果表明狀態(tài)性能評估模型生成工具的實用性良好。
[Abstract]:With the expansion of engineering construction scale and the improvement of technical requirements, the role of large-scale mechanical equipment in modern engineering construction has become more and more important. Truck crane is a kind of typical construction machinery equipment. Therefore, it is very important to evaluate the health status of its key components. At present, there are few targeted assessment models in the field of equipment health state evaluation, and there is a lack of remote control ability for the performance evaluation and intelligent maintenance of the whole machine system. In order to solve the above problems, this paper takes the QY90V truck crane as the research object, studies the data driven state performance evaluation theory method, experimental verification, technology integration and so on. The specific work includes:. 1) in view of the lack of evaluation model for the evaluation of construction machinery and equipment health condition, it is impossible to determine the health state of the equipment accurately. By studying the performance state description method of the equipment, and synthesizing the feature extraction and feature selection of the equipment signal, According to the standard flow of OSA-CBM(open system architecture for condition-based maintenance, a state performance evaluation system for multi-mode devices is developed. 2) the development of remote monitoring and diagnosis platform based on WEB. Through the research of WEB-GIS/GPS integration technology, embedded Google Earth / map technology and Web service technology oriented to users, the system framework of remote monitoring service platform based on SOA(service-oriented architecture is constructed. It provides software platform support for the development of remote monitoring and maintenance system for large mechanical equipment, and provides more flexibility for the practical application of enterprise users, and can increase the security of user platform system through user permission setting. Through the integration of the above theory, method and technology application, the development of the state performance evaluation model generation tool and the remote monitoring and control system of the automobile crane condition is realized, and the remote service system based on Web is realized at the same time. Taking the main pump bearing system of QY90V truck crane as the application object, the practical application of the diagnostic system on the monitoring platform of the network shows that the utility of the state performance evaluation model generation tool is good.
