Infrared diffuse reflection-based drunk driving telemetering system and telemetering method

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...

AI Technical Summary

Problems solved by technology

[0003] However, the traditional alcohol detection method is time-consuming and labor-intensive and needs to destroy the original traffic order, so it is impossible to implement it in large quantities; Pre-screening, there is currently no confirmed feasible solution

Relying on law enforcement officers to stop and inspect cars one by one is costly and obviously impossible to complete. This makes it very difficult for drunk driving detection and investigation of drunk driving drivers.
