The Application Of PROFIBUS Feld Bus In The Flat Wire Production

Flat wire workshop is the leading producer of woven bag workshop, to provide qualified flat wire for woven bag production. Flat wire production directly affect the quality of the finished bag and order after the efficiency of production. Flat wire workshop calculated at 330 days of work tasks,that Single average product capacity of 2800 tons/year and 4 production lines of annual output of 11200 tons,production Provides the guarantee for the supply of raw materials of next working procedure. The production line was completed and put into production in 2000, Signal transmission between the equipment adopts point-to-point control mode that failed to realize centralized management and decentralized control,so that further restricted the production. Drive control system of the hard line connection mode are increasingly exposed the problem such as vulnerable to interference and so on, that reduce the precision of the speed control. The above problems make the product quality and production efficiency. The speed control is always in the production process, realize accurate control of transmission speed flat silk production improve the stability and efficiency of production and guarantee the quality and performance of flat wire products have a decisive effect. In the production of flat silk PLC300 + PROFIBUS-DP field bus technology was adopted to realize speed regulation control, that Reconstruct the existing control mode. In order to solve the problems of the existing production lines and improve the plastic woven bag factory in my city industrial automation and informationization level, providing a certain reference.That this article through to the flat wire production line process flow, process parameters and main equipment structure and function analysis,it has been clear about the flat wire production each link speed control for the important influence of flat wire quality. Aiming at the shortcomings of the existing flat silk workshop speed regulation control, the article combined with the relevant technical requirements and user needs. By the advantage of PROFIBUS-DP network, the establishment of a flat wire production line based on PROFIBUS control system network structure. Completed the system hardware in terms of hardware component selection and configuration. The speed regulating control system were designed inverter wiring diagram. In the aspect of software configuration of the system of master station and slave station is completed as well as the master station and slave station communication program design, from communication of the master station PLC to that of slave station.The MCGS configuration software has completed the design of flat wire production line monitoring system.Laboratory simulation debugging results show that the pattern design of speed control based on fieldbus control system ’s good stability and open extensibility.
