INTEGRATED DRUNK AND DRIVE PREVENTION SYSTEM
ABSTRACT
As is needless to say; a majority of accidents, which occur, are due to drunk driving. As such, there is no effective mechanism to prevent this. Here we have designed an integrated system for the same purpose. Alcohol content in the driver’s body is detected by means of an infrared breath analyzer placed at the steering wheel. An infrared cell directs infrared energy through the sample and any unabsorbed energy at the other side is detected. The higher the concentration of ethanol, the more infrared absorption occurs (in much the same way that a sunglass lens absorbs visible light, alcohol absorbs infrared light). Thus the alcohol level of the driver is continuously monitored and calibrated on a scale. When it exceeds a particular limit the fuel supply is cutoff.
If the device is removed also, the fuel supply will be automatically cut off or an alarm is sounded depending upon the requirement. This does not happen abruptly and special indicators are fixed at the back to avoid inconvenience to other drivers using the highway signals. Frame work for integration of sensors and control module in a scalable multi-agent system is provided .A SMS which contains the current GPS location of the vehicle is sent via a GSM module to the police control room to alert the police. The system is foolproof and the driver cannot tamper with it easily. Thus it provides an effective and cost effective solution for the problem of drunk driving in vehicles..
WORKING
The infrared rays can be obtained with the help of ordinary infrared lamps. These have tungsten filament that can withstand heat up to 3000 c and they emit infrared light. In case the driver is drunk there will be a certain amount of alcohol in his breathe. This alcohol content in the breath will be relatively proportional to the amount of alcohol intake. The alcohol in the vapor state has the property of absorbing infra red light. The infrared light emitted passes through the air medium and reaches the sensor [PNA4602M], which detects the loss of the infrared light due to the absorption of alcohol present in the surroundings. This sensor then measures the loss by comparing the received amount of radiations with a fixed parameter that is predefined. The sensor is calibrated in such a way that the amount of loss is directly equal to the amount of alcohol present in the atmosphere. The energy consumed by the IR system is very less. Also the detection need not take place continuously. It can be done at discrete intervals.
