【摘要】：位于上层计划管理系统与底层工业控制系统之间的制造执行系统(ManufacturingExecutionSystem，MES)是现代生产制造过程中的车间生产管理和控制的信息系统。它能够为车间管理人员实时地提供生产计划的执行情况，生产车间的物料、设备和工作人员的状态信息，从而方便了生产活动的执行和调度管理。制造执行系统帮助企业在计划层与控制之间架起了“沟通”的桥梁，填补了企业计划层和控制层间的“鸿沟”。在目前制造业市场竞争日益激烈的条件下，制造执行系统为企业提高生产信息化和自动化水平，进而提升了企业的竞争力。本文研究的课题是面向MES的车间生产过程监控系统的研究，，拟采用构建于线缆企业生产车间的物联网作为制造执行系统（MES）的基础平台，通过生产车间一级的物联网实现线缆企业的生产、在生产、半成品及成品等生产信息的实时在线采集和监测，达成实时生产信息与ERP系统的无缝对接，实现线缆企业的全面的信息化管理。论文首先介绍了MES的国内外发展现状及车间生产过程监控系统发展现状。其次，本文详细阐述了MES系统的理念，分别介绍了MES的定义、MES的功能及MES的应用特点。然后，介绍了车间生产监控系统的网络组成方法，包括：车间生产监控系统特点分析；监控系统的网络设计要求；对基于现场总线（RS485、CAN、TCP）和基于无线网络（GPRS/GSM、ZigBee）的监控系统的分别说明。之后，通过物联网的关键技术以及框架需求等方面的分析，针对车间生产特点，从资源的合理运用和车间管理调度实时性出发，对物联网技术在生产监控系统的应用做了设计说明，具体有：ZigBee网络的介绍、物联网数据采集方法、生产品质数据追踪等。最后，本文以线缆企业生产车间为研究平台，介绍了系统的功能设计，具体说明了应用层网络协议，并对MES的终端系统的软硬件设计作了说明。
[Abstract]:Manufacturing execution system (ManufacturingExecutionSystem,MES), which is located between the upper planning management system and the bottom industrial control system, is the information system of workshop production management and control in the modern production and manufacturing process. It can provide workshop managers with real-time implementation of production plan, material, equipment and staff status information of production workshop, which facilitates the execution and scheduling management of production activities. The manufacturing execution system helps the enterprise to build a bridge between the planning layer and the control layer, and fills the "gap" between the enterprise planning layer and the control layer. Under the condition of increasingly fierce competition in the manufacturing market, the manufacturing execution system improves the level of production informatization and automation for enterprises, and then improves the competitiveness of enterprises. The research topic of this paper is the research of workshop production process monitoring system for MES. It is proposed that the Internet of things built in cable enterprise production workshop will be used as the basic platform of manufacturing execution system (MES). Through the Internet of things at the production workshop level to realize the production of cable enterprises, the real-time online collection and monitoring of production information such as production, semi-finished products and finished products can achieve the seamless connection between real-time production information and ERP system. Realize the comprehensive information management of cable enterprises. Firstly, the development status of MES at home and abroad and the development of workshop production process monitoring system are introduced. Secondly, this paper expounds the concept of MES system in detail, and introduces the definition of MES, the function of MES and the application characteristics of MES respectively. Then, the network composition method of workshop production monitoring system is introduced, including: the characteristics of workshop production monitoring system, the network design requirements of monitoring system, and the network design requirements of workshop production monitoring system. The monitoring systems based on field bus (RS485,CAN,TCP) and wireless network (GPRS/GSM,ZigBee) are described respectively. After that, through the analysis of the key technologies and framework requirements of the Internet of things, according to the characteristics of workshop production, starting from the rational use of resources and the real-time performance of workshop management and scheduling, The application of Internet of things technology in production monitoring system is designed and explained, including the introduction of ZigBee network, the data acquisition method of Internet of things, the data tracking of production quality and so on. Finally, taking the cable enterprise production workshop as the research platform, this paper introduces the functional design of the system, explains the application layer network protocol in detail, and explains the software and hardware design of the terminal system of MES.
