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 existing methods of car security are,Remote starters for car doors, Car with door lock module facility, Using motion sensors, Using tilt sensors and etc.,The drawback of these methods is that they fail to provide almost the higher security to the car. Similarly there is only manual information of accident to the hospital. There is no automatic accident information system. So our work fulfils these requirements. Our system uses the FPGA as the basic module to interface the GPS, GSM, RF modules.
II.GLOBAL POSITIONING SYSTEM:
The Global Positioning System (GPS) is a location system based on a constellation of about 24 satellites orbiting the earth at altitudes of approximately 11,000 miles. GPS was developed by the United States Department of Defense (DOD), for its tremendous application as a military locating utility. GPS has proven to be a useful tool in non-military mapping applications as well. GPS satellites are orbited high enough to avoid the problems associated with land based systems, yet it can provide accurate positioning 24 hours a day, anywhere in the world. Uncorrected positions determined from GPS satellite signals produce accuracies in the range of 50 to 100 meters. When using a differential correction technique, the users
