基于驾驶员身份认证的车载酒精检测系统设计

Abstract

近年来，我国机动车数量快速增长，交通事故成为危害公众安全的重要因素。事故成因包括超速、酒驾、疲劳驾驶等。本设计以单片机为控制核心，结合非接触式IC卡技术、GSM技术、传感器技术以及CAN总线技术，研究设计了一套基于驾驶员身份认证的酒精检测系统，通过IC卡绑定驾驶员与驾驶行为，通过酒精传感器对驾驶员入驾状态进行检测，根据检测结果进行预警，降低涉酒类交通事故的发生率。 In recent years, with the rapid growing of the quantity of motor vehicles in China, the traffic accident has become an important factor endangering the public security. The accident causes mainly include speeding, drunk driving and fatigue driving. The research shows that enhancing superintendency strength can effectively reduce the illegal operations of drivers. With the single chip processor as the core, combining with contactless IC card technology, GSM technology, sensor technology and controller area network bus technology, the study designs a set of the responsibility identification of driving system, which binds drivers and driving behavior through the IC card, automatically monitoring the driver status by using alcohol sensor before driving. According to the results of the detection, it gives the warning, and reduces the incidence of traffic accidents.
