摘要
本文介绍了点焊机群限容规划控制的原理及意义、系统的总体结构．给出了单机控制器的联机方法及ＫＤ７－１控制器联机的实例．讨论了主程序及几个子程序．本系统利用点焊机负载持续率低的特点，根据预定的限值，对同时通电焊机总容量进行限制，从而稳定了电网电压及焊接电流。
The principle and significance of the present planning control are introduced.The communication method of one timer with the control system,and its example with KD7 1 timer are given out.Then master program and some sub programs are discussed.This system makes use of the characteristic about lower duty cycle of spot welder,limits their general energized capacity at any time within a pre set limit in a spot welder group,thereby it stabilizes main voltage and weling current,enssures weling quality of the welder group.
