摘　　要：传统的自动化生产线实训台中的气动控制部分通常采用各个独立的气动控制阀类元件来控制执行机构动作,其要求安装空间较大,安装精度相对较低,安装技术要求高,使用不便。针对这些问题,提出一种基于现场总线Profibus-DP的总线型阀岛,替代传统的多个单一的气动控制阀元件,来提高控制准确度,加快自动化程度。同时,采用西门子S7-300可编程控制器(PLC)来控制整个系统运行过程。实验表明:该方法提高了控制精度,节省安装空间,使用便捷,使自动化水平进一步得到提高。Traditionally, pneumatic control parts in automated production line training equipments usually use many independent control valves. It requires large installation space and high installation technology, but the installation precision is low. To improve control accuracy and automation, the bus-valve island based on the fieldbus profibus-DP was introduced. The siemens $7-300 PLC was used to control the operation of the whole system. Experimental results show the control precision is improved, the installation space is saved, the automation of training equipments system is improved.
