【摘要】：隨著現(xiàn)代工業(yè)和信息科技的迅猛發(fā)展,如何通過(guò)大數(shù)據(jù)、云計(jì)算等新一代信息技術(shù)制定合理、系統(tǒng)的診斷策略,利用有限資源準(zhǔn)確快速地對(duì)包裝生產(chǎn)線故障進(jìn)行診斷,減少停工損失,是近年來(lái)學(xué)術(shù)界和工業(yè)界研究的一個(gè)熱點(diǎn)課題。包裝生產(chǎn)線結(jié)構(gòu)復(fù)雜,目前針對(duì)設(shè)備的故障診斷方法存在以下問(wèn)題:①?zèng)]有從運(yùn)行狀態(tài)數(shù)據(jù)出發(fā),對(duì)設(shè)備的各個(gè)部件的運(yùn)行狀態(tài)進(jìn)行分析;②技術(shù)門檻高,維護(hù)成本高。為此,本文提出了基于運(yùn)行狀態(tài)數(shù)據(jù)的包裝生產(chǎn)線在線故障診斷方法。論文主要研究的內(nèi)容如下:(1)闡述了包裝機(jī)械故障診斷方法研究的背景意義,首先介紹了包裝機(jī)械的應(yīng)用前景,對(duì)故障診斷方法的研究現(xiàn)狀進(jìn)行了分析,并提出現(xiàn)有研究的不足。(2)介紹了高速上袋機(jī)的結(jié)構(gòu)和工作原理,并從功能角度將上袋機(jī)分解成若干個(gè)子系統(tǒng)。其次,根據(jù)故障統(tǒng)計(jì)數(shù)據(jù),即靜態(tài)狀態(tài)數(shù)據(jù),對(duì)高速上袋機(jī)進(jìn)行了故障類型及其影響分析。最后,通過(guò)危害度分析法求出影響上袋機(jī)穩(wěn)定運(yùn)行的關(guān)鍵子系統(tǒng)。(3)定義了狀態(tài)數(shù)據(jù)并將其分類,設(shè)計(jì)氣缸(開(kāi)關(guān)類)動(dòng)態(tài)狀態(tài)數(shù)據(jù)和伺服(數(shù)據(jù)類)動(dòng)態(tài)狀態(tài)數(shù)據(jù)的采集裝置。(4)提出了三種故障信息元:過(guò)去型故障元,即時(shí)型故障元,預(yù)測(cè)型故障元。針對(duì)故障元的三要素:故障名稱、故障特征、特征值這三要素建立基于三者關(guān)系的故障診斷模型。(5)以伺服子系統(tǒng)為例,講訴故障診斷模型如何通過(guò)專家系統(tǒng)實(shí)現(xiàn)。
[Abstract]:With the rapid development of modern industry and information technology, how to make rational and systematic diagnosis strategy through new generation information technology such as big data, cloud computing, and use limited resources to accurately and quickly diagnose the fault of packaging production line,In recent years, reducing shutdown loss is a hot topic in academia and industry.The structure of the packaging production line is complex. The following problems exist in the fault diagnosis method of the equipment at present: 1. Without proceeding from the operation state data, the technical threshold is high and the maintenance cost is high for the analysis of the operation state of each component of the equipment.Therefore, an online fault diagnosis method for packaging production line based on running state data is proposed in this paper.The main contents of this paper are as follows: (1) the background significance of the research on packaging machinery fault diagnosis method is expounded. Firstly, the application prospect of packaging machinery is introduced, and the research status of fault diagnosis method is analyzed.The paper introduces the structure and working principle of the high speed bagging machine, and decomposes the bagging machine into several subsystems from the point of view of function.Secondly, according to the statistical data of the fault, that is, the static state data, the fault type and its influence on the high speed bagging machine are analyzed.At last, the critical subsystem of affecting the stable operation of the upper bagging machine is calculated by the hazard analysis method.) the state data is defined and classified.This paper presents three kinds of fault information elements: past fault element, instant fault element and predictive fault element, which are used to design dynamic state data of cylinder (switch class) and servo (data class).Aiming at the three elements of fault element: fault name, fault feature and eigenvalue, a fault diagnosis model based on the relationship between them is established. Taking servo subsystem as an example, how to realize the fault diagnosis model by expert system is discussed.
