摘　　要：通过对重载货运定位控制需求的研究,以西门子PLC和G120变频器为核心,提出并设计一种低速抱闸定位控制系统,从而实现了对重载货运较为准确的定位控制,避免了反复往返调试过程,提高了定位控制的效率。同时还采用触摸屏模块进行控制和监测,既增强了系统的可操作性,又提升了系统的可视化程度,最大限度提升了系统的灵活性和稳定性。Through the research on the positioning control requirements of heavy load freight, with Siemens PLC and G120 frequency converter as the core, a low-speed holding brake positioning control system is proposed and designed, thus achieving more accurate positioning control of heavy load freight, avoiding repeated round-trip debugging process, and improving the efficiency of positioning control. At the same time, the touch screen module is also used for control and monitoring, which not only enhances the operability of the system, but also improves the visualization degree of the system, and maximizes the flexibility and stability of the system.
