基于PLC和WinCC的混凝土搅拌站控制系统设计

Design of concrete mixing plant control system based on PLC and WinCC

通过对混凝土搅拌站系统的研究,采用以PLC为下位机、以工控机为上位机的混凝土拌站自动控制方式。系统以PLC为控制核心,WinCC为上位机的监控软件。通过应用PC Acces8软成功实现了WinCC与PLC之间的通信,从而使得WinCC组态的流程画面可以真实有效地反映出箔凝土搅拌站的工作状况。详细阐述了PLC模块选择、系统控制方案和WinCC的画面组态。该系统具生产效率高、工作性能稳定的特点,在试验运行过程中取得了良好的效果。

After the research of concrete mixing station system , we choose automatic control mode of concrete mixing station , which uses PLC as the lower computer and IPC as the superior machine . This system uses PLC as the control center , and WinCC is PC monitoring software . The communication between Wincc and PLC has been achived successfully by the application of the software PC Access , so the process screen of WinCC platform can truely and effectively reflect concrete mixing station′s operating condition . The article elaborates PLC module selection , system control program and WinCC platform in detail . This system has the characteristics of low cost , high production efficiency and stable performance , and achieves good effects in test run .
