Sutdy Of Digital Timing System Of Reversed Direct Current Based On ARM

This article carries on an application research about the full digital, reversibleness and double closed loop of DC motor system on the four-quadrant based on the ARM embedded system.With the embedded technology, hard real-time operating system, graphical interface and network communication technology, the research improves the design of the double-loop digital control system of DC motor based on traditional 8/16 SCM with Samsung's S344B0X 32-bit ARM processor, and attempts to explore and experiment the feasibility of its development. Taking full advantage of the ARM processor's multi-task procedure in the uc/os-II and uc/gui platform, real-time processing and user-friendly interface this design presents figures DC motor control program with logic uncircumflunce and reversibleness theory. and further explores using lwIP (a lightweight protocol package of TCP/IP for embedded systems) protocol to communicate with the PC machine for its long-distance remote control in the motor control aspect.This paper particularly describes the design's process of the DC drive system, and it consists of the following several parts:a. Introduce the concept and features of embedded system and its advantages and applications based on ARM processors.b. The design of full digital and reversibleness of DC motor controlling system.c. Multi-task software design based on the ARM and showing the idea and features of its design, finally presenting the concrete realization of main moduled. Finally introducing digital reconstruction and process of debugging for analog DC motor-experiment-platform based on ARM.It shows that the system has merits of simple circuitry, convenient control, dynamic undee display for motor's speed and network control and so on.
