Abstract
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 .关键词
