【摘要】：薄丝生产是卷烟制造中是至关重要的环节,对其控制方式的不同决定了成品烟质量的差异。目前大多薄丝生产线的控制方式基本是分散式的,但此种控制方式存在管理模式单一、控制精度低、不易维护等弊端,无法满足薄丝生产过程中各项指标的要求。本文提出了主从控制方式能达到对生产的集中式管理、对设备能进行实时的监控、应对突发情况能快速反应、操作性强、便于维护、以及在系统上可以进行相关的扩展等。基于PROFIBUS网络通信技术对薄丝生产中相关技术进行了改进,使用主从通信进行相关的控制,从而将原有的分散的控制设备以及系统连接起来,组建成了一个完整的网络。本课题的主要任务以及相关的研究工作如下:(1)在充分了解原有的薄丝生产线的基础上,对原有的生产工艺中相关的控制提出了改造,用基于PROFIBUS的S7通信技术代替原有的通信,从而可以将之前分散的控制系统集中起来,建立一个主从通信的系统。(2)本通信中主要是主从通信以及对其的相关控制。在文章中将会详细的介绍网络的连接结构、硬件的相关选型以及它们参数的相关配置和STEP7编程软件的相关分析等。根据薄丝生产的具体要求,设计了多站点、基于PROFIBUS、使用WinCC动态监控等结合在一起的控制系统。(3)本系统中采用SIMATIC WinCC对系统的运动控制进行实时的监控。由于该软件可以实时的对设备进行监控,避免了人工检测环节,从而更加保证了整体系统的安全可靠,同时也在无形中减少了企业人力成本的投入。本课题所设计的系统具有多个优点,例如设备智能化高、对数据的实时读取快、可操作性强、能对设备实时的动态监控等。整体方案在具体调试过后,经相关的实践证明,该系统运行稳定可靠、实用性高。
[Abstract]:The production of thin wire is a crucial link in the manufacture of cigarettes. The difference in the control mode determines the difference of the quality of the finished products. At present, most of the control modes of the thin wire production line are basically scattered, but the control mode has the disadvantages of single management mode, low control precision and easy maintenance, which can not meet the production process of thin silk. This paper proposes that the master and subordinate control method can achieve centralized management of production, real-time monitoring of the equipment, quick response to the emergency, strong operability, easy maintenance, and related extensions on the system. Based on PROFIBUS network communication technology, the related technology of thin silk production The main tasks and related research work of this subject are as follows: (1) on the basis of fully understanding the original thin wire production line and the original production process, the main task and the related research work are as follows. The control system is reformed, and the S7 communication technology based on PROFIBUS is used instead of the original communication. Thus the former decentralized control system can be concentrated and a master slave communication system is set up. (2) this communication is mainly the master slave communication and the related control. In this chapter, the connection structure of the network and the hardware will be introduced in detail. According to the specific requirements of the production of thin silk, a control system with multiple sites, based on PROFIBUS, using WinCC dynamic monitoring and so on is designed according to the specific requirements of the production of thin silk. (3) the real-time monitoring of the motion control of the system is carried out by using SIMATIC WinCC in this system. The software can monitor the equipment in real time, avoid the manual detection link, thus ensure the safety and reliability of the whole system, and also reduce the investment of human cost in the enterprise. The system designed in this project has many advantages, such as high intelligence of equipment, fast reading of the data, strong operability and ability. The real time dynamic monitoring of the equipment and so on. After the concrete debugging, the whole scheme has been proved to be stable and reliable and practical.
