Abstract

It is necessary to establish a system suitable for the driving vehicle so that it can effectively search for and modify various data anywhere and anytime by effectively linking communication with the computer system in the running vehicle and to control the equipment properly for smooth operation on a limited platform do. Also, vehicle CAN communication is used to extract system engine information, and data is transmitted using ZigBee for this information transmission. Therefore, OBD-II protocol, which is provided by the vehicle itself, is used for vehicle CAN to obtain vehicle status information and exhaust gas using various sensor information of the vehicle and O2 sensor value, and transmits it to the ZigBee main control system. In this study, we implemented a system that can reduce the battery load damage to the maximum by reducing the power consumption to the maximum, and to monitor the internal state of the vehicle through ZigBee communication with the embedded system for low power vehicles.

주행중인 차량내의 컴퓨터 시스템과 통신을 효과적으로 연계해서 언제, 어디서나 각종 데이터의 검색이나 수정 등이 가능하고, 제한적인 플랫폼에서 원활한 동작을 하기 위해 장비를 적절히 제어할 수 있도록 주행차량에 맞게 시스템이 구축되어야 한다. 또한 시스템 엔진 정보 추출을 위해 차량 CAN 통신을 이용하고, 이러한 정보 전송을 위해 ZigBee을 이용하여 데이터를 전송한다. 따라서 차량 CAN을 위해 차량에서 자체 제공되는 OBD-II 프로토콜을 사용하여 차량의 각종 센서 정보 및 O2 센서 값을 이용하여 차량 상태 정보와 배기 가스양을 구하고 ZigBee 메인 컨트롤 시스템에 전송한다. 본 연구는 저전력 차량용 임베디드 시스템으로 전력 사용량을 최대로 줄여서 배터리 부하의 데미지를 최대한으로 감소시키고, ZigBee 통신을 통한 차량의 내부 상태 모니터링을 할 수 있는 시스템을 구현하였다.
