基于 PLC 的教学用自动装配生产线研发

摘要

目前，工件的装配、检测、自动分类和自动上下料等工作在很多企业中都是由自动生产线来完成。开发相应的监控系统便能显示各工位状态，提高生产效率，避免人为因素造成的工件质量不稳定性。给出了教学用自动装配生产线控制及监控系统的设计与实现方法，设计中采用 SIMATIC S7-300、S7-200系列 PLC 和组态王构建了一个由 PLC 控制和上位机监控系统组建的典型工业控制系统，模拟一个与工厂生产过程接近的控制环境，增强了生产线的可靠性和实时性，具有操作方便、结构简单和实用直观等特点。%At present,the workpiece assembly,testing,automatic classification,automatic loading and unloading work are completed by the automatic production line in many enterprises.Development of monitoring system can display the corresponding position state,improve production efficiency and avoid the workpiece quality instability caused by human factors.The paper presen-ted the design and implementation method of teaching used in automatic assembly line control and monitoring system.The design used the SIMATIC S7-300,S7-200 PLC and KingView to construct a PLC and computer control system of typical industrial control system,to stimulate a control environment closed to the factory production process,so as to enhance the reliability,real-time pro-duction line,it has the advantages of convenient operation,simple structure,practicality etc.
