【摘要】 在制造业信息化的早期阶段,由于企业经营管理信息与制造设备自动化的相对独立发展,使得信息与制造的结合产生了阻碍,于是制造执行系统(MES)应运而生。多变的市场使得离散型企业迅速发展,离散制造在多品种小批量生产、生产流程多变、快速响应市场以及高水平生产质量管理等方面的需求日益突出,传统的数据采集手段已越来越不能满足MES在质量管理、车间作业调度和过程控制等方面的要求。近几年来,射频识别(RFID)技术发展迅速,满足了离散制造MES在生产现场数据采集方面的要求。因此,研究基于RFID的制造执行系统对推动离散制造业MES技术的深化与发展具有重要的实际意义。本文主要针对离散制造行业的特点及存在的问题,研究基于RFID的离散制造业MES方案及应用。在深入分析MES、RFID及其在离散制造业应用现状的基础上,提出了基于RFID的离散制造业MES应用方案,包括硬件的选择、RFID系统框架的构建以及基于RFID的MES软件功能的实现。在MES的功能构建上,主要研究了质量管理功能和生产监控功能。通过运用RFID的即时读写功能,记录生产数据,从而达到对产品的质量管理。通过RFID的识别追踪功能,监控整条生产线,从而了解生产线工作是否正常以及产品的生产情况。在软件功能的表现形式上,主要采用动态网页形式。通过RFID与数据库之间的数据存储记录相关生产数据,经过对相关数据的刷选、判断、分析、反馈最终实现相关功能。更多还原

【Abstract】 At the early stage of informationization in the manufacture industry, due to relatively independent development between the administration information and automatic production equipments, it makes an obstacle when the information and production are required to combine together. Then EMS emerges coping with the great demands in this environment. The changeable market requires the discrete enterprises to develop fast. In addition, discrete manufacture is facing to the demands on multi-type, small batch, changeable production, quick reaction and high-level of administration in productive quality. The conventional means of collecting data can’t meet the needs of EMS on quality administration, job-shop scheduling and process control. In recent years, RFID technology is developing rapidly, which meets the demands of discrete manufacture of MES (manufacturing execution system) on collecting the data of production spot. Therefore, the study based on RFID technology is meaningful for impeling the development of MES in discrete manufacture industry.Aiming at the characteristics of discrete manufacturing enterprises and existed questions, this thesis studies the application and scheme of RFID-based MES for discrete manufacture industry MES. On the basis of deep analysis of MES, RFID and current situation on the discrete manufacture industry, this thesis puts foreward the practical scheme of EMS based on RFID, including the selection of hardware, the construction of RFID system framework and the software development of RFID-based MES.On the function construction of EMS, this thesis mainly studies the function of quality management and production monitor. Through applying the function of instantaneous reading and writing, the production data can be recorded in real time, which can realize the quality management of the products. Through the identification and tracing function of RFID, the whole production line can be monitored so as to learning whether the production line is in the right order and to obtain the production information of the products.The dynamic web pages are designed as the expressing forms of software. Through the data storage in RFID and database, all production data can be recorded. And by the operations including selecting, judging, analyzing on the related data and feeding back to related departments, the efficient production management can be achieved.更多还原
