Electronic monitoring and protection system for drunk driver based on breath sample testing

This paper focuses on the problem of drunk driver which is represent one of the major reasons for traffic accidents during the last decades. Alcohol negatively affects the drunk driver judgment abilities and driving skills. Many engineering solutions have been proposed to reduce the consequences of drunk driving. However, most of these solutions were based on a certain type of control units or though computerized protection systems including wirelessly monitoring facilities. This resulted in having systems with demerits of complexity, high cost and slow response in the case of remote monitoring and remote decision making. These solutions were mainly dependendent on one type of controlling unit as well. To avoid all the above mentioned disadvantages, this paper introduces a simple, cheap and highly responsive design. The proposed design is based on discrete electronic components with processing and decision made locally and does not involve wireless transmission to guarantee the required fast response.

I. Introduction

The problem of alcohol drinking drivers and its consequences has increased in last decades due to the increase of car numbers and the increase in people who do not care about health and safety requirements during car driving. The brain of a human who drinks alcohol is affected within ten minutes of consumption due to the quick absorption of alcohol in the stomach wall. Consequently, the driving skills are negatively affected. Out of the drunk driver group, heavy alcohol drinkers have higher probaility of causing fatal accidents than others [1].
