摘要随着社会的不断发展,汽车也越来越普及,汽车偷盗问题以及酒驾问题越来越受到社会的关注。本课题主要设计一种将智能防盗及酒驾报警集成的智能汽车报警装置。
在分析实际应用需求基础上,制定了基于GPS和GSM模块的总体方案,车载终端采用Atmega128单片机为控制核心,通过GPS接收模块获取车辆的地理位置、时间以及速度等信息,经单片机判断车辆是否在非法情况下进行了移动;通过酒精气体传感器检测驾驶室酒精气体浓度是否超标,同时给设置的通信号码通过GSM以短信方式实时告知指定联系人车辆的具体位置以及酒精浓度超标的报警信息。23235

Title Intelligent alarm module of anti-theft and drunk driving
Abstract
With the development of society in recent years, the popularity of cars has been more and more widely spread. Cars theft and drunk-driving is increasingly affected by social concerns. This topic mainly focuses on an intelligent alarm device for smart car integrating intelligent security system and drunk-driving alarm system.
The program, which is on the premise to be practical, is made on the basis of GPS and GSM. Vehicle terminal use Single-Chip Microcomputer Atmega128 as control center to acquire the information on location, time and speed through GPS and then, to judge whether the car move illegally through Single-Chip Microcomputer. It use alcohol gas sensor to detect whether alcohol concentration in the cab is excessive, and send a message telling the location and super scale of alcohol to the owner through GSM.
Key words: Positioning and monitoring, GPS, GSM, Single-Chip Microcomputer , Gas sensor
