基于PLC的机电控制综合实验教学平台开发

Development of an integrated teaching platform for experiment of electromechanical control based on PLC

针对机电系统计算机控制实验教学的需要,设计开发了基于PLC的机电控制实训平台。该教学平台由PLC控制系统、实训/储水箱、水管管件、检测系统、执行系统等模块构成。采用该平台进行综合实验,学生可以掌握传感器的工作原理和应用领域、变频器控制被控对象的工作原理及实现方式、PLC编程控制的语言特点和控制方式,加深学生对PLC、上位机和被控对象之间工作关系的认识和理解,有效提高了学生机电液结合的动手与工程应用能力。

With the need of experimental teaching for the course of computerized control of mechatronical system(CCMS),this study develops a PLC-based experimental platform for practical training.The platform includes PLC control system,training/water storage tank,water pipe fittings,detection system and execution system.Using the platform for comprehensive experiments,students are allowed to master the working principle and application field of various types of sensors,the implementation procedure of controlling an object by the inverter,techniques and features of PLC programming.It will help to deepen the understanding of the working relationship between PLC,host computers and controlled objects,also enhance the ability of a student on practical operation and engineering application of an electromechanical system.
