基于PLC的加工中心控制系统的设计与应用 摘要 可编程控制器有于其在工业控制方面的应用意义日趋明显，并在发电、化工、电子等行业工艺设备的电气控制方面得到了广泛的应用。它具有功能强大、使用可靠、维修简单等许多优点，并且在很多地方已逐步取代了继电器电路的逻辑控制。 而本文讨论的是PLC在实际工业控制系统的应用。江南重工有限公司由于产业结构的变化和业务的发展，决定在原有的机械制造分厂的基础上成立一个轴系加工中心。由于整个轴系加工中心正在逐步建设和改善的过程中，许多设计还未付诸实施。本文仅通过某台设备电气控制系统的具体改造来作为重点展开叙述。对于整个中心的网络通信和网络化管理本文将在第四、第五章作初步的叙述和探讨。 关键词：可编程控制器，A1SJ71E71，多线程，Socket套接字 THE DESIGN AND IMPLEMENTATION OF PROCESS THE CENTER OF JIANGNAN’S CONTROL THE SYSTEMS Abstract Applied meaning that programmable controller have in its control the aspect in the industry gradually obvious, combine at generate electricity, chemical engineering, electronics etc. profession craft the equipmentss electricity control the aspect got the extensive application.It have the function strong and big, the usage is dependable, maintain the many advantage of simple etc., and already and gradually replaced after the logic control of the electric appliances electric circuit in a lot of places. But what the text discuss is a PLC in the actual industry to control the systems application.Heavy work limited company of JiangNan is because of the industrial structure that variety that development, decision establish a stalk to process the center is on originally possessed of the foundation that the machine manufacturing the cent the factory with the business.Because whole stalk process the center is at gradually developments with in the ameliorative process, the many design still did not put into execution.This text only passes the some set equipments the electricity control the systems of in a specific way reform to be used as the point to launch the description.The network correspondence of whole center manages with the network this text will make the first steps description in the fourth, chapter 5 with study.
