基于 PLC和单片机的多模式综合实验系统设计

摘要

Due to the diversity of industrial control ,the integrated control system becomes an industrial trend , more and more widely .Currently ,most colleges and universities have established the PLC and SCM lab ,the design enables students to master the widely used two control modes and system ,but most of them simply by the PLC or SCM make up control system ,lacking of integrated different control systems of experimental equipment and system .To be consistent with industrial trend ,so that students have related integrated control knowledge and practical ability ,this paper designs a kind of multi-mode integrated experimental system based on PLC and SCM , which consists of PC , PLC , SCM and inverter , contains PLC technology , SCM technology , frequency control technology , configuration software technology , merges a variety of communication interfaces and DDE data interactive mode .The practice proves that the system can greatly expand the horizons of the students ,and provide a good platform for integrated innovation experiment .%为了与工业发展趋势一致，使学生具有综合的相关控制知识与实践能力，将不同的控制系统进行组合，设计了一种基于PLC和单片机的多模式综合实验系统。该实验系统由PC机、PLC、单片机和变频器组成，集PLC技术、单片机技术、变频调速技术、组态软件技术于一体，融合了多种通信接口和DDE的数据交互模式。实验表明，该系统大大拓展了学生的视野，为开设综合性创新实验提供了良好的平台。
