The design and implementation of the real-time data analysis system for the thesis of the dissertation of the dissertationIn the rapid development and highly competitive market, it is difficult to continue the lasting competitive advantage by relying solely on marketing and product advertisement, and stable product quality is the root of the product. A number of companies are making steady productionQuality is considered a strategic objective and actively cultivates, develops and improves quality management and quality management talents.The quality control of silk thread in tobacco industry mainly refers to the production process of silk thread through the collection of cigaretteData in this paper, using the method of data detection and analysis to calculate the index of the index, to realize the control and guarantee of the quality control of the production process of the cigarette, is to control the result and control index. Computer skillsIn the rapid development of the control application of production process, the quality of the silk thread can only rely on the backward means of manual inspection, which can not control the quality effectively.In this paper, how to design, build the real-time data acquisition, analysis, and on the IT platform management system, implementation of jiangsu huaiyin cigarette factories silk ZhongYan industry company effective quality monitoring and management of production processThe study. Making silk real-time data analysis system "by using modern computer technology and the theory of statistical process control system of cigarette silk production, the control process of the real-time data acquisition, using statistical modelsCalculate and analyze the quality of cigarette production line. The main work of this paper is to analyze the main problems and needs of the product quality control of cigarette industry enterprisesSum characteristic, proposed the cigarette silk production lines in China in the process of real-time data acquisition, analysis and management system of the goal, task and conceptual model - how to use data analysis affecting cigaretteThe main cigarette technology parameters of the official quality; 2. Design and build the overall structure model of the real-time data analysis system of the silk thread. The system is mainly divided into real-time collection, data processing and collection, real-time analysis and automatic detection and alarmIn the four parts, the system is introduced to collect real-time data from the wire control system. After certain data processing, data calculation and analysis are carried out, and the abnormal problems are automatically alerted. Apply statistical process controlThe technology is used to process, calculate and analyze the quality data collected in real time, and use the result of analysis to control the production in real time. The evaluation and research on the quality of cigarette and the judgment of the control chartThen the data model is established to study the quality of cigarette perception, and how to apply the control diagram to the system.This system USES the Windows operating platform, VB6.0 as the development tool, and the C/S architecture is adopted to realize the functions of the system. The results show that the system can collect, eliminate, calculate and divide accuratelyAnalyze the quality data, find out the quality problems in real time, classify the quality problems, and automatically alarm the system when the quality runs abnormal, so that the quality problems can be detected and controlled in time. The system not only raises the silk threadThe quality control level is also provided to provide a strong guarantee for the quality of the products.3. Research on the key technology of reverse engineering in the rapid prototyping of the thesisRapid prototyping technology (RPM) is the frontier of modern technology, and the introduction of reverse engineering (RE) in RPM is of great significance to realize the information integration between RE/RPM, thus forming a set design.Manufacture, testing in one of the quick feedback design system. So, with the development of the modern computer technology and testing technology, the use of CAD/CAM technology, advanced manufacturing technology to realize the reverse engineering of physical products, has becomeA research hot spot in CAD/CAM field, and the main content of the application of anti-engineering technology.This paper by scanning point cloud data as the research object, emphatically in the point cloud data processing, integration of reverse engineering and rapid prototyping manufacturing, the key technology and surface reconstruction and carried on the thorough researchThe main tasks of this thesis are as follows:(1) point cloud data processing, mainly from the point cloud data acquisition, the classification of the point cloud data, as well as the pretreatment of the point cloud data were studied.
