[Abstract]:Drawing is the last process to improve and improve the spinning quality, which plays a decisive role in the quality of cotton sliver. Therefore, the high performance drawing frame plays an important role in the textile industry. Although the domestic textile industry has been developing rapidly in recent years, the medium and high grade drawing machines are still imported from foreign countries as a whole equipment or controller, and a high-performance drawing machine with independent intellectual property rights has been developed. Is still the textile machinery industry transformation and upgrading of the key task. This paper mainly discusses the autoleveller control system based on ARM FPGA architecture, including the principle of autoleveller, the whole structure of the system, the software and hardware realization of the system, the debugging of the system and the production experiment. In this paper, the drawing theory and the basic principle of autoleveling are discussed in detail from the angle of drafting structure and control principle. After explaining the principle, this paper then analyzes the design requirements of the control system, then puts forward the system solution of ARM FPGA according to the requirement, and expounds the overall structure of the control system in detail. The control system is mainly composed of hardware circuit and software program. After the system structure is clear, this paper begins to elaborate the software and hardware functions of the system and its implementation, which is also the focus of this paper. Firstly, the structure of hardware circuit board is described, then the function, structure and realization of each module of FPGA are described in detail. Finally, the realization of system software and algorithm based on ARM is described in combination with flow chart. The autoleveller control system described in this paper has been installed on the D101L drawing frame and has been put into operation for a long time. The actual production experiments show that the control system has ideal leveling effect and can improve the quality of cotton significantly. Moreover, the system has a good stability for a long time and can meet the actual production requirements well.
