题目:过程控制系统课程设计

摘要:

可编程控制器是一种数字运算操作的电子系统,专为在工业环境下应用而设计。它采用了可编程序的存储器,用来在其内部存储执行逻辑运算,顺序控制、定时、计数和算术运算等操作的指令,并通过数字式和模拟式的输入和输出,控制各种类型的机械或生产过程。可编程控制器及其有关外围设备,易于与工业控制系统联成一个整体,易于扩充其功能的设计。可编程控制器对用户来说,是一种无触点设备,改变程序即可改变生产工艺。目前,可编程控制器已成为工厂自动化的强有力工具,得到了广泛的普及推广应用。

该课程设计介绍了可编程序控制器(PLC)和PLC控制系统的基本知识,包括PLC的定义、特点、分类、技术指标、基本结构、工作原理、硬件知识及PLC控制系统等相关知识。
