Friction Press Control System Design Based On DSP

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 workload.According to the friction of the press control system, the paper elaborated on the various control part of the realization of ideas to the relevant principles, and introduced the system of hardware and software components. TMS320F2812 to elaborate on the chip at the core of the smallest circuit various components of the system, the touch-screen interface circuit, photoelectric encoder interface circuits, and other hardware circuit design process and demonstrated the actual production of the PCB board. The control system software also conducted a preliminary study, presented in various parts of the control flow chart.In this paper, the design of friction with the press control system at the core of the PLC control system compared to the cost is much lower, and real-time control and accuracy have been enhanced, for the future of the DSP in the forging equipment lay in improving the Basis.
