【摘要】：随着当今市场的快速变化和现代制造业的发展与转型,制造业正逐步向多品种小批量生产、能够快速响应市场变化及生产流程多变等方向转变。伴随着这种转变,企业对生产车间的信息化提出了更高的要求。然而,我国的制造企业多年来采用的生产制造过程是传统模式,它的生产特点是“由上而下”,这就使得企业的车间控制层和计划层之间出现了信息“断层”现象。制造执行系统(Manufacturing Execution System,MES)是面向车间执行层的管理信息系统,它能够在企业信息管理层与制造单元的设备控制系统之间架起一座桥梁,从而解决上述“断层”问题。而解决这个问题就需要信息的及时获取和信息交换。在MES中引入物联网技术,利用各种信息感知设备实时获取物体的各种动态信息,然后通过网络技术将这些物体传感器连接起来,再对这些信息进行智能处理,从而实现对生产车间物体与设备的管理、协调与控制,取得更大的经济效益。本文对正逐步向小批量、多品种的生产方式转变的制造业,特别是机加工车间等典型的离散类制造车间进行分析,提出利用基于物联网的车间制造执行系统来解决此类制造企业的“断层”现象,并给出具体的MES系统设计思路与框架；此外利用RFID技术和ZigBee技术具体设计出了制造车间物联网系统平台,实现了生产车间的各种数据的采集、实时监控与传输；同时综合工业工程流程分析方法与管理信息系统理论,对离散制造业车间的管理信息响应与信息交换的需求、车间生产任务管理、工艺信息管理以及产品与组织结构等环节进行分析后,利用Justep X5开发平台实现了MES系统；最后成功将物联网技术与MES系统互联,实现了生产车间信息的响应与及时交换,使车间的生产息化程度加强、可视化程度提高,并对该平台进行装配车间生产线流程的实例验证。
[Abstract]:With the rapid changes of the market and the development and transformation of the modern manufacturing industry, the manufacturing industry is gradually changing to multi-variety and small-batch production, which can quickly respond to the market changes and the changing production process. Along with this change, the enterprise to the production workshop information put forward higher requirements. However, the manufacturing process adopted by manufacturing enterprises in our country for many years is a traditional mode, and its production characteristic is "from top to bottom", which makes the information "fault" appear between the workshop control layer and the planning layer of the enterprise. Manufacturing execution system (Manufacturing Execution System,MES) is a management information system for workshop execution layer. It can build a bridge between enterprise information management and equipment control system of manufacturing unit, thus solving the above "fault" problem. To solve this problem, it is necessary to obtain and exchange information in time. The technology of Internet of things is introduced into MES, and various kinds of dynamic information of objects are acquired in real time by using various information perception devices. Then these object sensors are connected by network technology, and then the information is intelligently processed. Thus, the management, coordination and control of objects and equipment in the workshop can be realized, and more economic benefits can be obtained. This paper analyzes the manufacturing industry which is gradually changing to the production mode of small batch and variety, especially the typical discrete manufacturing workshop, such as machining workshop, etc. A workshop manufacturing execution system based on the Internet of things is proposed to solve the "fault" phenomenon of this kind of manufacturing enterprises, and the design idea and framework of the MES system are given. In addition, the platform of Internet of things in manufacturing workshop is designed by using RFID technology and ZigBee technology, which realizes the collection, real-time monitoring and transmission of all kinds of data in the workshop. At the same time, integrating the methods of industrial engineering process analysis and management information system theory, the management information response and information exchange demand of discrete manufacturing workshop, workshop production task management, After analyzing the process information management, product and organization structure, the MES system is realized by using Justep X5 development platform. Finally, the Internet of things technology and MES system are connected successfully, which realizes the response and timely exchange of information in the workshop, strengthens the production information degree of the workshop, and enhances the visualization degree. The platform is verified by an example of assembly workshop production line flow.
