摘　　要：以矿用圆环链大容量闪光对焊机为研究对象,在简要介绍焊机机构和焊接工艺的基础上,设计了对焊机的控制系统硬件结构和软件程序。控制系统以西门子S7-200PLC为控制核心,搭建了控制系统硬件模块并对各模块完成了选型。重点讨论了控制软件的设计流程,利用软件编程实现了焊接工艺的预热、闪光、重复闪光、顶锻等过程,上位机采用了工业触摸屏,对触摸屏系统软件界面进行了详细设计。同时系统中加入了上位机控制,提高了整个系统的可靠性和可操作性。经过工业现场验证表明,环链闪光对焊机运行稳定、故障率低,满足了市场的需要。In this paper,the hardware and software of the control system of high-capacity mining circle chain flash butt welding machine were designed based on a brief introduction of welders and welding institutions. The PLC200 of Siemens was used as the core of controller. The hardware modules of control system were selected. The design process of the software was discussed. The preheating welding process,flash,repeating flash,upset processes were realized by the program edited by software. The industrial touch screen was used for the PC part. The sub-interfaces for each system,such as parameter setting,real-time curve and the fault query interface were introduced in detail. While a PC is added in the control system,the reliability and operability of the system is improved. The industrial trials show that chain flash butt welding machine has a highly stability,low failure rate,and meets the needs of the market good.
