Research And Design Of A Embedded System For Alarm Of Vehicle

In the past, most intelligent electrolic products of vehicle are controlled by singlechip processor. But with the development and enhancement in the functionality of those products, the control with singlechip processor can't meet the actual demand. Presently an obvious trend is to adopt embedded system. In this paper, an alarm system of vehicle based on mobile telephone long-distance control mechanism is designed using the embedded processor chip-S3C44B0X of Samsung ARM7 processor.This paper firstly introduces the theory of embedded system which includes ARM architecture, program mode and Pipeline structures. Secondly we propose the framework for the overall design and present the detail the working mechanism, system hardware design and implementation, the design idea of software based on component and implementation of the control software based on the idea. The embedded technology, GPS technology and GPRS wireless communication technology are used in our system. The use of these technology are explicated in the paper.Based on the theory and technology, an alarm product mode of vehicle has been accomplished and the control software has been designed. The paper finally gives the result of system test. Through testing, the system can work well and achieved a stable performance.
