摘　　要：通过对盘绞式成缆机工作过程的分析,说明了对收线电机的控制要求,采用AT89C51单片机为控制核心,通过检测旋转编码器在单位时间内输出的脉冲数,与标准脉冲数进行比较,控制收线电机调速器的给定值,从而控制收线电机的旋转速度,实现了线缆的均匀走线速度控制。给出单片机与旋转编码器组成的闭环线速度控制系统的电路原理及主要控制程序的设计方法。其简洁的电路设计和典型的控制方法具有较高的参考价值。The requirements of control for the pulling motor are illustrated by analyzing the working process of a disk stranding cabling machine.Taking AT89C51single-chip computer as the core of controller and comparing the number of the pulses exported by rotary encoder in unit time with that of the standard pulse to control the given value of the speed governor for the pulling motor,the rotation speed of the pulling motor is controlled,and the control of cable uniform speed is achieved. The circuit principle and the design methods of main control program of closed-loop line speed control system are given.The simple circuit design and typical control method have a certain reference value.
