Vlsi Based Accident Information and Car Security System

Abstract: VLSI based Accident information and car security system deals with the concern of saving the victim , who get trapped in accident and also about the car security. Accident of the car is detected using pressor sensors which are fixed in car. Accident information to the nearest hospital is carried out with the help of RF communication. The location of the car is found using the GPS technique. The security of car is ensured by using password. The theft information is sent to the owner’s mobile using GSM module. The ultimate design of the project is in VLSI. FPGA is used to interface these modules. Keywords: Very Large Scale Integration, Global Positioning System, Global System for Mobile Communication. I.INTRODUCTION: The†¦show more content†¦By comparing the codes, the time difference between the satellite generated the code and the receiver generated the code can be determined. This interval is the travel time of the code. Multiplying this travel time, in seconds, by 186,000 miles per second gives the distance from the receiver position to the satellite in miles. D. Increased accuracy by using differential gps: A technique called differential correction is necessary to get accuracies within 1 -5 meters, or even better, with advanced equipment. Differential correction requires a second GPS receiver, which is a base station, collecting data at a stationary position at a precisely known point (typically it is a surveyed benchmark). Because the physical location of the base station is known, the correction factor can be computed by comparing the known location with the GPS location determined by using the satellites.The differential correction process takes this correction factor and applies it to the GPS data collected by a GPS receiver in the field. Differential correction eliminates most of the errors listed in the GPS Error Budget discussed earlier. III.GLOBAL SYSTEM FOR MOBILE COMMUNICATIONS The Global System for Mobile Communications (GSM) is the most popular standard for mobile phones in the world. GSM service is used by over 2 billion people across more than 212 countries andShow MoreRelatedAsaaaa3527 Words   |  15 PagesLOGIN SEARCH ACTIVE TOPICS Electrical, Electronics Communication Projects Projects Q A, Guidance for your projects  » Projects Forum  » Electrical, Electronics Communication Projects Ads by Google Alarm Monitoring System Alarm House Alarm System Telephone System Topic: ECE Mini Projects Found this useful?
