人机交互在桥式起重机自动定位系统中的实现

The Realization of Human-machine Interface in Automatic Positioning System of Bridge Crane

基于松江河水电厂传统桥式起重机行走定位方式技术改造项目,阐述了人机交互在控制系统中的组态应用及实现方法,通过WINCC flexible 2008组态软件及西门子S7200 SMART构建自动定位系统,可将HMI及PLC连接到一起,实现点击触摸屏发出指令桥机自动定位。实际应用表明,人机交互的使用简化了操作,实现了桥机定位的自动控制。

Based on the technical transformation project of the traditional bridge crane walking positioning method of Songjianghe Hydropower Plant,the configuration application and realization method of human machine interface in the control system are described in this paper.To construct an automatic positioning system through WINCC flexible 2008 configuration software and Siemens S7200 SMART,HMI and PLC are connected together to realize automatic positioning of the bridge machine by clicking on the touch screen and issuing instructions.Practical application shows that the use of human machine interface simplifies the complexity of operation and realizes automatic control of bridge crane positioning.
