摘要

根据国内外同类机型及类似设备设计了用可编程序控制器实现压机热压曲线的设定及存储的方案。该方案可以允许用户同时存储２０条热压曲线，每条热压曲线由２０个线段组成，每条曲线的第２０个线段是一个不可由用户更改的三级热压机开启程序，以利于操作的安全性。程序中设有出错保护，可避免用户输入错误的参数。

Abstract

A method of setting and storing of parameters for press controlled with pro-grammable logical controller is introduced. According to this design, 20 pressing curves couldbe stored in the memory of PLC. Each curve is divided into 20 sections, The 20th section,which is not allowed to change by users for safety of operation,is a fixed step for opening ofthe press. Parameters for all the other 19 sections storing in the memory can be set by usersand be retrieved for use.
