Study On The Intelligent Fiber Optic Winding System For Fiber Optic Communication Delay Ring

Fiber optic communication delay ring is an optical device used to delay optical signals,widely used in fields such as optical communication,sensing,and radar system.The production of fiber optic rings requires the use of professional fiber winding equipment to wind special fibers onto the fiber optic skeleton according to requirements such as volume,length,and optical performance.In order to solve the problems of high winding cost,poor tension control accuracy during the winding process,insufficient defect detection accuracy,and inability to accurately locate the wrong position of current fiber optic winding equipment,it is crucial to conduct research on low-cost,stable,and highly automated intelligent fiber winding machines,which has important theoretical significance and engineering application value.The research content of the paper is as follows:(1)Research on the scheme and mechanical structure design of fiber optic ring wrapping machine.The causes of tension generation and types of winding defects during the fiber optic winding process were studied,Based on this questions,the functional and accuracy requirements of the fiber optic winding machine were proposed,and the mechanical structure of the fiber optic winding machine was designed,including winding execution mechanism,tension detection mechanism,automatic wire arrangement mechanism,and visual detection mechanism,to ensure the stability of the fiber optic winding machine.(2)Design of fiber optic winding machine system.A fiber optic loop system was built based on the Xilinx ZYNQ platform,which adopts an FPGA+ARM architecture and is divided into two parts:the system hardware and software platform.FPGA completes the construction of the system hardware platform and utilizes the parallel computing advantages to complete the hardware module driver,which can collect real-time winding images and perform image acceleration preprocessing.The motion control and algorithm design of fiber optic winding are based on ARM,with tension control,high-precision wire arrangement,and defect detection algorithm based on peak coordinates.When there are winding defects,automatic feedback and correction are provided to meet the requirements of high efficiency and fully automatic winding.(3)Testing and analysis of the entire fiber optic winding machine.The rationality of the mechanical structure and the effectiveness of tension control and defect detection functions were verified through a large number of actual ring tests.The results show that the tension control system has good control effect during the ring winding process,and the tension control accuracy can reach±0.5 g at a ring winding speed of 30 r/min.The detection accuracy of ring defects reaches 4.25 μm.The accuracy rate reaches 94%,and the running speed can meet the real-time detection requirements.After winding,the finished fiber optic ring is evenly arranged,with a unit loss of less than 0.2 d B/km,indicating that the quality of the fiber optic ring meets the requirements.
