The Reaserch Of μC/OSII Embedded System And The Application On Turntbale Control

As a modern science and technology, computer science and technology had made rapid development. As an important branch of computer technology, embedded-system technology has become the most viable one. It has been widely used in industry, agricultural production, defense industry, defense science and technology, health and other economic spheres.Paper chose real-time embedded-systemμC/OSⅡas the research and application object in a variety of common embedded software platforms for digital controller, Based onμC/OSⅡembedded-system and the application of its principle, Paper carried out a detailed analysis and description, gave out the detailed steps on transplantingμC/OSⅡto the ARM microprocessor core. With this embedded-system platform, Paper succeeded to realize the digital control of the two-axis simulate turntable.Papers in the first chapter had a detailed account of the commonly used system for embedded profiles, as well as the characteristics of real-time embedded-systemsμC/OSⅡ.Building embedded platform was the focus of this paper of Chapter II, Paper competed the strengths and weaknesses of existing embedded-systems on application scope andμC/OSⅡwas chosen as the software control platform. The content of this chapter is divided into two parts: the first part detailed the working principle and application methods ofμC/OSⅡand in accordance with the hardware environment, paper described the important component: Bootloader; In the latter part, the article analyzed the general approach of transplantingμC/OSⅡ. Paper also gave out some key steps in detail, as well asμC/OSⅡtransplanting laws was summarized.In the third chapter, Paper described the structure of control systems and gave out the design of the interface circuit.Finally, in Chapter IV and V, Based on the thesis that the tasks required, Paper gave out the digital controller software for the realization of the program. Paper also encountered technical difficulties with a corresponding code. Papers ultimately realized the digital controller platform construction. On this basis, it completed the control software and interface circuit design. Paper gave out a successful application. By detecting the turntable, all targets were in accordance with the mandates book. That proved the feasibility of digital control system based onμC/OSⅡembedded platform.
