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
