基于PCI总线的新型捻线机传动与控制系统

新型捻线机的控制系统多采用多电机传动系统,目前国内主要采用单片机控制,针对其控制系统的缺点,设计了基于PCI总线的新型捻线机传动与控制系统。传动系统采用4个电动机的多电机传动,运用解析法对新型捻线机的多电机传动系统进行运动分析,建立适合多电机传动系统的数学模型,综合运用交流伺服技术、变频调速技术和PCI局部总线控制技术,结合捻线工艺理论设计出合理的控制系统。通过程序实现锭子转动、筒子卷绕和导纱杆往复运动控制。结果表明,设计的传动与控制系统能实现新型捻线机的加捻卷绕的工艺目标。

A novel transmission and control system for twisting machine based on PCI bus

Most of the control systems of the latest twisting-machine adopt the multi-motor drive system. However, at present in China, the use of single chip processor for its control is still popular. Aiming at the shortcomings of the control system, a new type transmission and control system based on PCI bus technology is developed, which is a multi-motor transmission system of four motors. An appropriate mathematic model has been developed. The running of spindles, the winding of bobbins and the reciprocate of guiding-yarns are controlled in phase by the control system, which is based on the integration of the AC servo technology, the frequency conversion technology, the PCI local bus technology and the twisting theory. Experiments show that the design of the transmission and control system can achieve the process objectives of winding of the latest twisting machine.
