基于虚实结合的港口装备控制实验平台

On Experiment Platform of Port Equipment Control System Based on the Combination of Virtual with Actual Object

针对港口装备控制实验因缺乏相应实验设备难以有效开展的现状,提出了虚实结合的港口装备实验平台概念。利用Flexsim软件搭建起港口装备的三维仿真控制模型,对其进行二次开发,实现将模型状态信息写入Excel电子表格并且同时从中读取控制信号;利用Win CC组态软件与PLC组态通讯,并且通过读写Excel实现控制信号与反馈信息在控制硬件PLC与虚拟模型之间传递。该实验平台突破了大型实验装备缺乏的限制,可为港口大型装备相关控制实验的开展提供对象模型,实现控制过程的三维可视化,对大型装备实验开展具有借鉴意义。

The controlling experiments of port equipments could not be carried out properly due to the lack of appropriate equipment,so the concept of combination of virtual and actual object was proposed. Flexsim software was used to build the 3D simulation model of port equipment and was redeveloped to read and write Excel file. Win CC software was used to configure communication with PLC which realized the control and feedback signals transmission between PLC and Flexsim model by reading and writing Excel file. The Experiment platform broke the limit of equipment. It could offer us object models to do the experiments about port equipment and achieves 3D visualization of control process. The experience has a reference value for similar experiments.
