【摘要】：制造执行系统（Manufacturing Execution System，MES）是面向车间生产过程的实时信息管理系统。数据采集功能是MES的基础模块，其能否及时反馈生产过程中的数据，对MES实现其计划、优化、过程透明等作用至关重要。本论文主要研究QR Code条码技术及其在面向离散制造企业的MES系统数据采集中的具体应用。在概述MES的同时，分析了面向离散制造企业MES系统的总体框架与功能结构，描述了数据采集对其它功能模块的支撑关系，，并由此提出“QR Code条码技术+触摸屏”的数据采集解决方案，作为对现有数据采集系统的补充和优化。 QR Code具有开放性的标准、特有的汉字字符集、能高效地表示汉字，因此更适合我国企业的应用需求。本文对QR Code符号结构及编码流程进行了分析，重点研究了编码过程中的RS纠错算法。采用基于多项式除法的算法程序，成功生成纠错码字，并在存有网址的QR Code符号生成过程中得到验证。条码技术是集编码、印刷、识别、数据采集和处理于一身的技术。在分析QR Code条码技术与MES系统之间的集成需求及集成总体框架的基础上，制定了基于语义的条码生成规则；以VC6.0为开发工具设计了硬件程序管理器，实现了条码硬件设备与MES系统之间的信息传递及与业务流程的相融合；通过采用实时数据库存储技术，确保信息查询与反馈的高效性。以某企业制造车间为例，通过明确MES系统需要采集的数据及信息元素，探讨、研究了QR Code条码技术在MES系统登录、生产任务执行、车间事件管理、设备状态数据采集等方面的具体应用及实现方法。
[Abstract]:Manufacturing Execution System (MES) is a real-time information management system for workshop production process. The function of data acquisition is the basic module of MES. It is very important for MES to feed back the data in the process of production in time. It is very important for MES to realize its plan, optimization, process transparency and so on. This paper mainly studies the QR Code bar code technology. And its application in data acquisition of MES system for discrete manufacturing enterprises.
At the same time, the general framework and functional structure of MES system for discrete manufacturing enterprises are analyzed, and the support relation of data collection to other functional modules is described, and the data collection solution of "QR Code bar code technology + touch screen" is put forward as a supplement and optimization to the existing data acquisition system.
QR Code has an open standard and unique Chinese character character set, which can express Chinese characters efficiently, so it is more suitable for the application needs of Chinese enterprises. This paper analyzes the symbol structure and coding process of QR Code, and focuses on the RS error correction algorithm in the encoding process. And is verified in the process of generating QR Code symbols with web addresses.
Bar code technology is the technology of coding, printing, recognition, data acquisition and processing. Based on the analysis of the integration requirements and integrated framework between QR Code barcode and MES system, the rules of bar code generation based on semantics are formulated. The hardware program manager is set up with VC6.0 as a development tool, and the bar code hardware is set up. The information transmission between MES system and business process is integrated, and real-time database storage technology is adopted to ensure the efficiency of information inquiry and feedback.
Taking an enterprise manufacturing workshop as an example, by clarifying the data and information elements that the MES system needs to collect, this paper discusses the application of QR Code barcode technology in MES system login, production task execution, workshop event management, equipment state data collection and so on.
