基于Profibus-DP技术的D530焊装线控制设计与实现

摘要

The SIEMENS S7-400 large PLC and Profibus-DP bus technology are introduced firstly, which served as the control core and network communication basis of automatic mixed-flow welding line of D530 separately.Then, the design idea and method of its electric control system are explained in detail. Also, the realization method of data communication between the upper line device of side head cover and the main line PLC DP is given. The DP bus technology is applied successfully, it explains the design of welding line control system is viable,reasonable and forerunner, has good apply value to expand in car welding line.%介绍了以西门子S7-400大型PLC为控制核心、以Profibus-DP现场总线技术为基础的多层工业网络技术在D530自动混流焊装线控制系统中的应用,阐述了D530焊装线电气系统的设计思想、设计方法以及侧围顶盖上线装置与主线PLC DP数据通讯的实现方法.DP总线技术的成功应用,说明了焊装线控制系统的设计是可行的、合理的和先进的,在汽车车身焊装线上具有很好的推广应用价值.
