【摘要】：近年來(lái),“工業(yè)4.0”和“互聯(lián)網(wǎng)+”概念的深入人心,使得制造生產(chǎn)過程中的信息化越來(lái)越受到企業(yè)的重視。在以往加工過程中,當(dāng)生產(chǎn)設(shè)備不能正常工作時(shí),管理人員無(wú)法立即得到故障信息,當(dāng)產(chǎn)品生產(chǎn)完成后遇到質(zhì)量問題時(shí),無(wú)法排查到具體工步。究其原因是缺乏對(duì)車間設(shè)備加工數(shù)據(jù)的有效采集手段,無(wú)法實(shí)時(shí)監(jiān)控到機(jī)床的狀態(tài)信息和加工工藝參數(shù)。并且當(dāng)下的生產(chǎn)監(jiān)控系統(tǒng)多采用二維界面進(jìn)行操作,人機(jī)交互體驗(yàn)較差,不利于車間工作人員的使用。為了彌補(bǔ)這些不足,本文提出了車間生產(chǎn)數(shù)據(jù)處理與可視化的新方法,設(shè)計(jì)了一套基于虛實(shí)融合的車間實(shí)時(shí)生產(chǎn)監(jiān)控系統(tǒng)。論文主要內(nèi)容如下:(1)對(duì)車間生產(chǎn)數(shù)據(jù)的采集方式和類型進(jìn)行研究,實(shí)現(xiàn)了生產(chǎn)數(shù)據(jù)的傳輸、解析等功能。對(duì)車間生產(chǎn)數(shù)據(jù)進(jìn)行分類,并針對(duì)不同類型的數(shù)據(jù)選擇合適的通訊傳輸協(xié)議,編寫服務(wù)器端數(shù)據(jù)采集軟件和文件夾監(jiān)控軟件,對(duì)客戶端上傳的生產(chǎn)數(shù)據(jù)進(jìn)行接收。(2)對(duì)生產(chǎn)數(shù)據(jù)的存儲(chǔ)過程進(jìn)行研究,實(shí)現(xiàn)了對(duì)生產(chǎn)數(shù)據(jù)的管理。根據(jù)設(shè)備代碼和信息類型創(chuàng)建相應(yīng)表單,并對(duì)表單間的數(shù)據(jù)關(guān)系進(jìn)行梳理,采用觸發(fā)器對(duì)存儲(chǔ)數(shù)據(jù)進(jìn)行監(jiān)控,實(shí)現(xiàn)異常報(bào)警功能。同時(shí)針對(duì)數(shù)據(jù)的查詢進(jìn)行優(yōu)化,減少系統(tǒng)性能開支,提高數(shù)據(jù)庫(kù)的響應(yīng)速度。(3)基于虛擬現(xiàn)實(shí)技術(shù),實(shí)現(xiàn)車間生產(chǎn)過程的三維可視化。首選通過對(duì)虛擬現(xiàn)實(shí)技術(shù)的研究和應(yīng)用,搭建出基于車間實(shí)際狀況的虛擬生產(chǎn)場(chǎng)景。其次對(duì)部分設(shè)備的加工動(dòng)作進(jìn)行分解和制作,利用編碼技術(shù)實(shí)現(xiàn)數(shù)控設(shè)備三維模型的生產(chǎn)動(dòng)作模擬。最后對(duì)車間生產(chǎn)虛擬場(chǎng)景進(jìn)行優(yōu)化,減少渲染開支,在不降低用戶觀感的前提下提高電腦的運(yùn)行效率,增強(qiáng)系統(tǒng)的穩(wěn)定性。(4)完成了生產(chǎn)數(shù)據(jù)驅(qū)動(dòng)的基于虛實(shí)融合的車間實(shí)時(shí)生產(chǎn)監(jiān)控系統(tǒng)。對(duì)虛擬車間場(chǎng)景與網(wǎng)頁(yè)間的數(shù)據(jù)交互方式進(jìn)行了研究,設(shè)計(jì)了功能調(diào)用函數(shù)接口和數(shù)據(jù)交互格式,并利用網(wǎng)站開發(fā)技術(shù)將車間虛擬場(chǎng)景和生產(chǎn)數(shù)據(jù)進(jìn)行了集成,實(shí)現(xiàn)了數(shù)據(jù)庫(kù)、網(wǎng)頁(yè)和虛擬車間場(chǎng)景之間的數(shù)據(jù)傳遞,添加了歷史數(shù)據(jù)查詢、實(shí)時(shí)狀態(tài)顯示、設(shè)備利用率分析等功能,實(shí)現(xiàn)了車間的生產(chǎn)監(jiān)控。目前,該虛實(shí)結(jié)合的車間實(shí)時(shí)監(jiān)控系統(tǒng)已經(jīng)投入到實(shí)際生產(chǎn)中,并取得了良好的使用效果,實(shí)現(xiàn)了對(duì)車間實(shí)時(shí)生產(chǎn)過程的監(jiān)控功能。
[Abstract]:In recent years, the concepts of "industry 4.0" and "Internet" have been deeply accepted by people, which makes the informatization in manufacturing process more and more important. In the past, when the production equipment can not work properly, the manager can not get the fault information immediately, and when the product is finished, it can not find out the concrete steps when the quality problem is encountered. The reason is that there is a lack of effective means to collect machining data of workshop equipment, and it is impossible to monitor the state information of machine tools and process parameters in real time. And the current production monitoring system uses the two-dimensional interface to operate, the man-machine interaction experience is poor, which is not conducive to the use of workshop staff. In order to remedy these shortcomings, a new method of data processing and visualization of workshop production is proposed, and a real-time production monitoring system based on virtual reality fusion is designed. The main contents of this paper are as follows: (1) the collection method and type of production data in workshop are studied, and the functions of transmission and analysis of production data are realized. According to the classification of workshop production data and the selection of appropriate communication protocols for different types of data, the server-side data acquisition software and folder monitoring software are written. The storage procedure of production data is studied, and the management of production data is realized. According to the device code and information type, the corresponding form is created, and the data relationship between the forms is combed. The trigger is used to monitor the stored data, and the abnormal alarm function is realized. At the same time, the query of the data is optimized, the system performance expense is reduced, and the response speed of the database is improved. (3) based on the virtual reality technology, the 3D visualization of the workshop production process is realized. Through the research and application of virtual reality technology, the virtual production scene based on the actual situation of workshop is built. Secondly, the machining action of some equipments is decomposed and made, and the 3D model of NC equipment is simulated by coding technology. Finally, we optimize the workshop production virtual scene, reduce the cost of rendering, and improve the running efficiency of the computer without reducing the user's perception. Enhance the stability of the system. 4) complete the production data driven workshop real-time production monitoring system based on virtual-reality fusion. This paper studies the way of data interaction between virtual workshop scene and web page, designs the function calling function interface and data exchange format, and integrates workshop virtual scene and production data with website development technology, and realizes the database. The functions of data transfer between web page and virtual workshop scene, such as historical data query, real-time status display and equipment utilization analysis, are added to realize workshop production monitoring. At present, the real time monitoring system has been put into practical production, and has achieved a good effect, and realized the monitoring function of the workshop real time production process.
