Embodiment Construction

[0049] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0050] Such as figure 1 As shown, a drunk driving telemetry system based on infrared diffuse reflection, including infrared diffuse reflection sensor, is used to scan the road section, receive the diffuse reflection infrared light signal in the road vehicle, and convert the diffuse reflection infrared light signal into an electrical signal and output it to the spectrum Analyzer;

[0051] The spectrum analyzer 2 is used to receive the electrical signal output by the infrared diffuse reflection sensor 1, and extract the effective second harmonic signal of the electrical signal;

[0052] The terminal controller 6 is used to analyze the effective second harmonic signal extracted by the spectrum analyzer, determine whet...

Abstract

The present invention relates to an infrared diffuse reflection-based drunk driving telemetering system and telemetering method, a vehicle passing through a road is scanned by an infrared diffuse reflection sensor installed on the road, incident infrared light can be selectively absorbed by alcohol gas inside the vehicle cab, and the absorbed laser light can be reflected on the reflecting surface; a diffuse reflection infrared light signal is received and analyzed, and the alcohol gas concentration inside the vehicle driving cab can be determined, and timely teletransmitted and reported to facilitate drunk driving checking and the like. The remote drunk driving non-contact detection can determine in real time whether a driver in the vehicle is suspectable to be in drunk driving. In the field of dangerous driving detection in intelligent transportation, the infrared diffuse reflection-based drunk driving telemetering system can greatly assist law enforcement departments to master the personal state of the drive in the vehicle, so that law enforcement officers can specifically check the drive in drunk driving, at the same time, the deterrent effect on the drunk driving behavior can be significantly improved, and traffic accidents caused by the drunk driving can be effectively reduced.

Description

technical field [0001] The invention relates to the technical field of intelligent transportation, in particular to an infrared diffuse reflection telemetry system and a telemetry method for drunk driving based on modulation spectrum. Background technique [0002] The results of traffic accidents in various countries show that the number of traffic accidents caused by drunk driving is 16 times that of non-drinking situations. According to the blood and breath alcohol content thresholds of vehicle drivers and the inspection standard GB19522-2004, a blood alcohol concentration greater than or equal to 20mg / 100mL and less than 80mg / 100mL is regarded as drinking and driving; a blood alcohol concentration greater than or equal to 80mg / 100mL is regarded as drunk driving. At the same time, research data show that before a drunk driving accident, the driver has performed an average of more than 500 drunk driving behaviors. In order to effectively reduce the number of traffic accide...
