In the process of Soft fiber product, there always exist some problems in Fiber unit, whichseriously affected the quality of products and soft fiber yield, through the analysis of, we foundthat it was mainly due to tight fiber-off device control system. Tight Buffer Fiber cable tensioncontrol systems include strain-sensing device and the tension control two aspects, because theequipment manufacturers have different design ideas so the tension control is not the same, butall have one thing in common is adopting PID control. This kind of control mode under thecondition of the production line speed fluctuation is not big system can well satisfy therequirement of the tension control, but the speed of the volatile situation under tension can’t wellsatisfy the control requirements, and thus it’s need to find a new control method. In addition, inorder for workers operate and well understand the status of the actual operation to the feedingdevice, it need the system data, real time curve and history curve for monitoring, at the same time,it’s helpful to build the fault alarm record for display. Because which makes it convenient tolooking for.It redesigned tightly packaged fiber pay-off device, the survey line speed change and tightlypackaged fiber is a kind of nonlinear relationship between the actual tension, it is difficult to setup the mathematical model, and therefore the subject put forward the PID control and fuzzycontrol constitute a dual-mode control. When the production line speed fluctuation is not big, thesystem uses the PID control. However, when the production line speed fluctuation is big, thesystem uses the fuzzy control.The system also chooses the control system scheme of systemrequired tension sensor, servo control system, inverter, pulse conversion card hardware selection,such as the choice of hardware adhere to the principle of the high cost performance, not onlyensure the performance of the system and reduces the manufacturing cost of the equipment. Atthe same time, the subject use Siemens S7-300PLC in the control system for software design,software design, through modular structure, the convenient also write convenient debugging ofthe system, it is the basis of the control scheme. In addition, for the convenience of equipmentoperation and monitoring system, the paper through kingview6.52software design of themonitoring interface, which laid the foundation of information management for the futureenterprise.This topic successfully solved the problem of controlling the tightly packaged fiber pay-offtension, its useful to the improvement of the hose line product percent of pass, it not only savesthe production cost of manufacturer, but also saves the social resources. At the same time, it’shelpful to improve the production efficiency of hose line, because the feeding device does notworry about fluctuation of tightly packed of high-speed optical fiber pay-off tension control effect. Secondly, to other optical fiber, optical fiber cable and cable tension device of the improvementof the performance of the control system play a certain reference function.
