基于plc原理设计的自动售货机.doc

大庆石油学院本科毕业设计（论文） 摘 要 在今天的工业生产中，可编程序控制器已经成为实现工业自动化的关键。本文简要介绍了有关可编程序控制器的一些基础知识和三维力控组态软件的简单应用，而且，还介绍了可编程控制器的技术特点，并重点在硬件、软件和组态软件方面进行了介绍。对它们在工业自动化中的典型应用、必威体育精装版的技术发展趋势也作了介绍。 在这次毕业设计中，我以PLC原理为基础、利用三维仿真力控软件设计了自动售货机系统，利用松下编程软件FPWIN-GR编制了相应的PLC应用控制程序并进行了调试和三维力控组态软件ForceControl编制了自动售货机系统，完成了设计的基本要求. 采用可编程序控制器进行实际生产过程控制，顺序严格，可靠性高。 关键词：可编程序控制器；自动售货机；仿真；三维力控组态软件 Abstract In today’s factories, programmable logic controllers(PLC) have become the key building blocks of industrial automation. Some basic knowledge of programmable logic controller is introduced in the paper. Moreover, the technical features, application status and technology development of PLC is presented in this paper. The hardware, software and network structure of PLC are introduced in detail. An introduction of their typical applications in industrial automation, the latest development trend and system considerations are also introduced. Vending machine system is regarded as a project to design the programmable logic controller practical system. The applied system design of water treatment system is finished by the use of FP1 C24 programmable logic controller and ForceControl 2.6. Controlling software about this system are designed, While emulation research are done in the lab. Good succession and high reliability of real production process control due to the use of programmable logic controller are available. The analog test method given in the paper may be applied to lab teach.
