DESCRIPTION
FIELD OF THE INVENTION

The present invention relates to generally to the field of alcohol detection systems and more particularly to an intelligent alcohol detection system for automotive vehicles incorporating ignition interlock capability, reporting, operator identification and vehicle location systems using GSM and GPS navigator’s and a method thereof , thereby prevent the number of accidents occurring due to drunk driving.

BACKGROUND OF THE INVENTION

In recent years, the popularity of the vehicle also caused drunk driving traffic accidents, drivers often have luck, unaware of the dangers of drunk driving, to people's lives and property caused a great threat; the traffic police department limited staff and limited law enforcement cannot be detected in real time every drunk driving incident. Drunk driving of a vehicle (for example, automobile) is now a serious social problem. A driver is therefore strictly prohibited from driving a vehicle under the influence of alcohol drinking. However it all depends on a driver whether he or she refrains from driving a vehicle after drinking alcohol.

Many countries have established monitoring programs for persons who have been convicted of drunk driving on one or more occasions. The monitoring programs include monitoring the blood and/or breath alcohol concentration of those convicted of drunk driving, and prohibiting them from driving if it is found that the blood and/or breath alcohol concentration level of the convicted person is above a pre-established threshold limit.

In recent years, a drunk driving detection system for detecting an alcohol drinking condition of a driver has been developed to reduce the number of accidents caused by drunk driving. Further, studies are made on various systems for controlling the start and operation of a motor vehicle (hereinafter referred to as “vehicle”) based

on the output from the drunk driving detection system.

JP 2005-224319A proposes technology, which forcibly restrains a driver under the influence of alcohol drinking from driving a vehicle. According to this technology, an alcohol detection device (alcohol concentration measurement device) is provided in a vehicle so that an engine start operation is prohibited, for example, unless the alcohol detection device confirms that the driver is free from the influence of alcohol drinking.

US 7377352 B2 discloses a vehicle ignition interlock system includes a breath analyzer and a controller operably connected to the breath analyzer and to an ignition system of the vehicle. The breath analyzer detects the breath alcohol level of a vehicle operator and is configured to prevent vehicle ignition if a breath alcohol level is greater than or equal to a threshold value. The controller requires the vehicle operator to periodically take breath analyzer “retests” after vehicle ignition in order to allow vehicle operation to continue. The breath analyzer also includes a mouth contamination sensor that is configured to distinguish between contaminants in the mouth of a vehicle operator and alcohol contained within a deep lung breath sample of the vehicle operator. The controller may require a breath alcohol retest of the vehicle operator via the breath analyzer in response to detecting the presence of a contaminant within the mouth of the vehicle operator.

CN 202541327 U discloses a utility model provides an intelligent vehicle mounted alcohol detection and safety control system. The system comprises a pressure sensor, an alcohol sensor, a voice module, a single chip, an LCD (Liquid Crystal Display) display screen, a relay and an automobile ignition braking device, wherein the single chip is connected with the pressure sensor, the alcohol sensor and the voice module; the single chip is connected with the LCD display screen by an alcohol concentration display module; the single chip is connected with the automobile ignition braking device by the relay; the pressure sensor positioned at the lower part of a driver seat is used for judging whether a driver enters the driver

4

seat or not; through the voice module, the single chip is used for reminding the driver of detecting alcohol by using the alcohol sensor; the single chip is used for judging whether the driver is in drunk driving according to a detection result; if the driver is in drunk driving, the single chip is used for sending out alarming through the voice module; meanwhile, the automobile ignition braking device is controlled by the relay so as to stop the driver in drunk driving from starting an automobile in a forced way. According to the utility model, as alcohol detection and automobile braking safety are combined, the driver can be effectively prevented from driving while being drunk while alcohol detection and judgment are duly carried out on the driver.

Prior art systems for alcohol detection/testing in vehicular applications typically employ breath or vehicle interior gas detection for alcohol vapor. Systems for alternative detection forms have been costly and most systems are complex and/or excessively expensive or do not provide desired reliability in detection.

Despite the aforementioned prior arts and disadvantages in the conventional detection system , there stands a need to provide an alcohol detection system which employs reduced complexity while providing precise detection capability. It is further desirable for the system to measure a potential driver’s intoxication level by use of breath analyzer and automatically interlock the ignition system of the vehicle and provided with a GSM, wherein a message will be sent to family member of the driver along with his position with use of GPS Navigator by use of smart phone.

Said system comprises of a microcontroller; a vehicle ignition interlock system ; a GSM and GPS module and an alcohol sensor.
