苏州职业大学 触摸屏控制异步电动机的探讨 姓名: 莱庆典 学号:1220310324 班级:电气11大1 专业:电气自动化 指导老师:何志伟 2014年6月19日 触摸屏控制异步电动机的探讨 摘 要 可编程逻辑控制器(Programmable Logic Controller,PLC),它采用一类可编程的存储器,用于其内部存储程序,执行逻辑运算、顺序控制、定时、计数与算术操作等面向用户的指令,并通过数字或模拟式输入/输出控制各种类型的机械或生产过程。 可编程逻辑控制器实质是一种专用于工业控制的,其硬件结构基本上与微型计算机相同可编程逻辑控制器三菱公司推出的高性能小型可编程控制器FX2N,FX系列PLC中应用最广泛的产品,该系列PLC是1991年推出,因其具有较高的性能价格比,受到广大用户的青睐.FX2N系列PLC是采用整体式和模块式相结合的叠装式结构。Abstract Programmable Logic Controller (Programmable Logic Controller, PLC, it USES a Programmable memory, used for its internal storage procedures, to perform the Logic operation, sequence control, timing, counting and arithmetic operations such as user-oriented instructions, and through the digital or analog input/output control various types of machinery or production process. Programmable logic controller is a specialized in industrial control computer, its hardware structure is basically the same as a microcomputer. This article is based on programmable logic controller PLC and touch screen software design three-phase asynchronous motor star triangle step-down start system and monitoring system. This design USES mitsubishis high-performance small FX2N series programmable controller to control the three-phase asynchronous motor star triangle step-down startup system, FX series PLC, the most widely used products in the series of PLC was introduced in 1991, because of its high cost performance, get the favour of the masses of users. FX2N series PLC is the combination of the integral and modular stack structure. By ladder diagram programming language more straightforward, so that the electrical systems run automatically according to the requirement, and second, the three-phase asynchronous motor star triangle step-down starting system of touch screen monitor system is to realize the real-time monitoring data. This article mainly includes the description of the process control and the design of electric system, the overall design of the principle of star triangle decompression system of mits
