Excitation Adjusting Equipment Based On ARM9 Embedded System

With the development of computer technology and the demand-driven,real-time embedded system design methodology have been great changes.Early in embedded real-time system development focusing on improving based on the CPU speed of implementation efficiency,development methods rely on direct processor-based software,without the use of real-time operating systems,the system software and application software are not separately.Now embedded real-time system development more value products interface to the network protocol support and other factors.We build the hardware platform chosen embedded ARM9 processor as CPU,the Linux operating system,which are open source code, free of network support such advantages, Embedded Linux choice as to the operating system to facilitate application development, to equip the system with small volume,high reliability,dedicated strong cost performance advantages of ideal.The embedded numerical control system,which is based on the ARM chip and Linux operation system,is a high integration of ARM technology,embedded operation system and the Excitation.It is an exploration of the combination of the Excitation control technology and the embedded computer technology.With LSI technology and the development of computer technology,a microprocessor as the main characteristics of the digital electronic technology applied to the modern AVR control system,replace transistors or integrated circuits consisting of traditional analog AVR.Hardware used as a control microprocessor core of the PC excitation device will become automatic excitation device development direction.The main focus of this paper is the development of the Man-machine Interface (MMI) program of the Excitation equipment. The focus of this paper is to design and develop an embedded interface program.This study is going to cover three key aspects:first,the structural composition of the software and hardware of the embedded system as well as the realization plan; second, the design and development of the embedded MMI program; third, Embedded Development Board driving.
