摘要
目前,查处酒驾常用的接触式酒精检测方法精度较高,但不能实时检测,效率很低。为了更有效地监控驾驶员的酒驾行为,开发了一套实时监测驾驶员饮酒状况的非接触式酒驾检测系统,并搭建一个由O2/CO2传感器、气敏酒精传感器及微处理器等组成的气体酒精浓度检测平台。阐述了非接触式酒驾检测系统基于呼气气流检测的检测原理和主要结构组成,介绍了气体酒精浓度检测平台的硬件设计以及对该检测平台的标定实验,实验结果显示平台检测值与接触式酒精检测值之间存在良好的线性相关度。
At present, the commonly-used method by means of contact alcohol detection which investigates drunk driving has high precision,but it can not realize real-time detection and therefore the efficiency is very low. In order to monitor the driver＇s drunk driving behavior more effectively, a non-contact drunk detection system used to real-time monitor the driver＇s drinking status has been developed and a gas strength of alcohol detecting platform comprised of the 02/CO2 sensor, the gas alcohol sensor and microprocessor has been built. It expounds the detection principle and primary structure composition of non-contact drunk detection system based on expiratory flow detection, introduces the hardware design of gas strength of alcohol detecting platform as well as the calibration experiment to this detecting platform. The experimental result shows that the platform examination value and the contact alcohol detection values have high degree of linear correlation.
