【摘要】 随着科学技术的发展,工业生产走向了自动化、智能化、信息化时代,工业4.0更是加快了这一步伐。机器视觉发展也越来越成熟,广泛应用于各行各业。国内石英锭的生产大多是开环控制系统,造成了石英锭尺寸不标准,资源浪费严重,同时降低了生产效率,阻碍了生产的自动化水平的提升。基于此,本文提出了基于机器视觉技术的石英锭料位情况的分布式监控系统,该系统是闭环控制系统,实现了实时反馈和智能控制,实现了生产标准化,节约了资源,同时提高了石英锭生产的自动化和智能化水平。本文监控系统采用了机器视觉、分布式系统、PID控制等技术方法。首先,分析了系统功能需求,介绍了设计原则,提出系统总体方案,完成可行性分析。接着,介绍系统采用的理论方法,完成了机器视觉系统的设计并进行了图像处理,运用多种滤波和图像分割方法进行效果对比,完成了石英锭料位高度、宽度、面积、斜率等计算,介绍了分布式系统原理和PID控制算法。最后,完成控制系统的设计和仿真,系统采用windows环境进行监控软件的研发,分析了软件功能需求和设计要求。本文研究的是石英锭生产的料位监控系统,系统采用闭环控制原理,通过实时反馈和智能控制,提升了石英锭生产监控的可控性和可靠性,使石英锭的生产更加标准化、自动化、智能化、信息化。更多还原

【Abstract】 With the development of science and technology,industrial production has also moved toward an era of automation and intelligence.Industry 4.0 has even accelerated this pace.The more mature the development of machine vision,is widely used in various fields.The production of domestic quartz ingots is mostly open-loop control systems,resulting in non-standard quartz ingots and severe waste of resources.With regard to material level monitoring,there are still artificial observations,which greatly reduce the production efficiency and hinder the improvement of the automation level of production.Based on this,this paper proposes a distributed monitoring system based on the machine vision technology for the quartz ingot level,the system is a closed-loop control system,which realizes real-time feedback and intelligent control,realizes production standardization,saves resources,and improves the automation and intelligence of the production of quartz ingots.The monitoring system of this paper adopts such technical methods as machine vision,distributed systems,and PID control.Firstly,the functional requirements of the system is analyzed,introduces the design principles,proposes the overall scheme of the system,and analyzes the feasibility of the system scheme.Then,the theoretical techniques used in the system are explained,the design of the machine vision system is completed and the image processing is performed,and the effects are compared using various filtering and image segmentation methods.The calculation of the height,width,area and slope of the quartz ingot was completed.The principle of distributed system and PID control algorithm were introduced.Finally,the design and simulation of the control system are introduced.The system uses windows environment to develop the monitoring software,and analyzes the software function requirements and design requirements.This article studies the level monitoring system for quartz ingot production.The system adopts the principle of closed-loop control system.Through intelligent control,the controllability and reliability of quartz ingot production monitoring have been improved,making the production of quartz ingots more standardized,intelligent and informative.更多还原
