Abstract

The invention discloses a drunk driving quick detection device and method based on dual-wavelength laser remote sensing, wherein the device comprises a laser emitter, a laser emitter control portion,an emitting portion, a light condensing portion, a light detection and signal analysis portion and a light reflecting portion; the laser emitter is composed of two lasers having wavelengths within alcohol and moisture absorption peaks and deviating an absorption region into moisture absorption peaks; the laser emitter control portion includes a laser drive control module and a temperature controlmodule; the emitting portion is composed of a laser beam coupling lens unit and a beam expander unit; the light reflecting portion is composed of an angle reflector; the light condensing portion is composed of a parabolic concentrator and a D-type reflector; the light detection and signal analysis portion is composed of a photoelectric detector and a computer. The device and method herein are suitable for identifying alcohol content in a fast moving vehicle, identification errors in real-time monitoring can be decreased, and background errors due to sunlight and other backgrounds can be decreased.

Description

technical field [0001] The invention relates to the technical field of alcohol concentration, and more specifically, to a device and method for rapid detection of drunk driving based on dual-wavelength laser remote sensing. Background technique [0002] At present, the number of automobiles in my country is developing rapidly. While automobiles bring convenience, the loss of personnel and property caused by road traffic accidents is also increasing day by day. Among them, traffic accidents caused by drunk driving account for a large part. The tragedies brought about happen every day. The public security traffic management department has also invested a lot of manpower and material resources in the investigation of key time periods and locations. However, since it is impossible to determine whether the motor vehicle driver is drinking or not, they can only investigate the vehicles one by one. This is not only inefficient but also affects normal traffic. [0003] The tradition...
