摘要
21 世纪的制造业,正从以机器为特征的传统技术时代,向着以信息为特征的技
术时代迈进,即用信息技术改造和提升传统产业。汽车工业作为衡量一个的标志,其发展主导了锻压技术及装备的发展,锻压技术的发展和进步基本围
绕汽车工业的发展而进行。摩擦压力机作为一种实用的锻压设备,以其低廉的价格,
具有非常广阔的应用前景,它的研究和开发对于提高具有重要意义。
本文从摩擦压力机的研究背景出发,阐述了摩擦压力机的工作原理以及工作方
式,在介绍其工作原理的基础上,提出了利用 DSP 为控制核心来代替传统的 PLC 的
方案,在提高了装备的技术性能和可靠性,将 PLC+单片机的系统整合成一个 DSP
系统的同时,还大大降低了安装、调试的技术要求和工作量。
根据对摩擦压力机控制系统的分析,本文详细阐述了各个控制部分的实现方案
以相关原理,并介绍了该系统的硬件软件组成。详尽阐述了以 TMS320F2812 为核心
芯片的最小系统各个组成部分电路、触摸屏接口电路、光电编码器接口电路等硬件
电路的设计过程,并展示了实际制作的 PCB 板。对控制系统的软件也进行了初步探
讨,给出了各个部件的控制流程图。
本论文设计的摩擦压力机控制系统与 PLC 为核心的控制系统相比在成本上有很
大的降低,并且实时性和控制精度都有所提高,这为将来的 DSP 在锻压设备中的改
进打下了基础。

Abstract
The manufacturing industries in 21 century, from machinery to the characteristics of
traditional technology era, toward information-technology features of the times ahead, that
is, using information technology to transform and upgrade traditional industries. The
automobile industry as a measure of a country’s level of industrial signs, the forging of
their development-led technology and equipment development, forging technology for the
development and progress on the development of the automobile industry to. Friction
Press as a practical advanced forging equipment, with its low price, has a very broad
prospects, and its research and development for improving the performance of domestic
equipment, enhance the country’s industrial level is of great significance.
This article from the friction on the background of the press, the press described the
working principle of friction and working methods, and the introduction of its work on the
basis of principle, to the use of DSP core for the control of the PLC to replace the
traditional ideas, to improve the equipment The technical performance and reliability, will
PLC + SCM systems integration into a DSP system, it is also greatly reduced the
installation, commissioning, technical requirements and wo
