摘  要:随着工业自动化水平的迅速提高,PLC 和组态仿真技术在工业控制领域中得到了广泛的应用。为了适应这一发展趋势,提高应用型本科院校的工程应用能力,在高校“电气与PLC 控制技术”课程教学中,开展组态软件与PLC 的教学十分必要。本文以工程机械产品泵车控制为例,介绍了德国西门子公司产品S7-300 PLC 与上位机组态软件WinCC 在教学中的应用。组态监控软件能较好地模拟现场生产实践情况,具有操作、报警、监控、存储、打印的功能,通过MPI、PROFIDS-DP、点对点等多种通讯方式,能与PLC 实现通讯,并可以对现场设备进行状态及运动监控。WinCC 具有人机界面友好,图库丰富,交互性强,性能稳定等优点。通过对该课程进行教学实践改革,有利于提高应用型本科学生的工程实践能力和技术创新能力。

Abstract:With the rapid improvement of industrial automation level,PLC and configuration simulation technology have been widely used in the field of industrial control. In order to adapt to this trend and improve the engineering application ability of applicationoriented undergraduate colleges,it is necessary to carry out the teaching of configuration software and PLC in the course of “Electrical and PLC Control Technology” in colleges and universities. In this paper,the application of S7-300 PLC and WinCC in teaching is introduced,taking the control of pump truck as an example. Configuration monitoring software can simulate the field production practice well,and has the functions of operation,alarm,monitoring,storage and printing. It can communicate with PLC through MPI,PROFIDS-DP,point-to-point and other communication modes,and can monitor the status and movement of field equipment. WinCC has the advantages of friendly man-machine interface,rich library,strong interactivity and stable performance. Through the teaching practice reform of this course,it is beneficial to improve the engineering practice ability and technological innovation ability of applied undergraduate students.

Keywords:PLC;WinCC;pump truck control system;configuration;engineering practice
