基于PLC的生产流水线监控系统设计毕业设计论文.doc

摘 要 随着当今社会科学技术的日新月异，各类物料输送的生产线对自动化程度的要求也越来越高，原有的生产送料装置，已远远不能满足当前高度自动化的需要。保障生产的安全性、可靠性、降低生产成本、减少环境污染、减轻劳动强度、提高产品的质量及经济效益，是企业生存和发展所必须面临和解决的现实问题。 本课题是研究通过PLC系统来控制生产线，监控组态来模拟监控界面，实现生产的自动化，可视化。本课题首先设计PLC控制系统，根据要求实现的功能分配IO口，接线，然后编制通过V4.0 step 7软件进行梯形图的编辑、运行，并把现场的小车运行状况实时传送给上位机，上位机采用力控组态软件进行监控。 监控组态是通过力控ForceContro7.0软件进行监控界面的编辑、运行。首先设计监控界面，设置通信参数和IO口，使得上下位机能够可靠通信。上位机监控系统主要通过按钮控制完成电机正反转，电动机正反转灯的显示，传送带的正反转，电动机的正反转控制小车的前进与后退及各种指示工位灯的颜色变化控制等功能。将各个部件的动作脚本编辑程序，实现了生产流水线的小车运行状态监控。 关键词：PLC；监控组态；状态监控；力控 Abstract Abstract This topic is the study of the PLC system to control production lines, monitoring configuration to simulate the monitoring interface, production automation, visualization. Monitoring configuration is controlled through the power of software to monitor interface ForceControl7.0 edit, run. Power Control Power Control 6.0 ForceControl7.0 in adhering to proven technology, based on the historical database, HMI, I / O driver scheduling and other major core improvements were significantly improved with redesigned one of the core components. Through PLC software ladder editor, run. editing software for Siemens series of industrial products including SIMATIC S7, and -based programming, monitoring and parameter setting, SIMATIC industrial software is an important part. has the following features: hardware configuration and parameter setting, communication configuration, programming, testing, start-up and maintenance, document filing, operation and diagnostics functions. have all the features extensive online help, use the mouse to open or select an object, press F1 to get help for the object.With the rapid changes in science and technology in society today, various types of material handling automation production line of the increasingly high demand, the original production of feeding device, can not meet the current needs of a high degree of automation. Protect the production of security, reliability, lower production costs, reduce environmental pollution, reduce labor
