Infrared alcohol detector and detection method thereof

Abstract

The invention discloses an infrared alcohol detector and a detection method thereof. The detector comprises an infrared detection mechanism, an infrared thermal imaging mechanism and a main machine, wherein the infrared detection mechanism and the infrared thermal imaging mechanism are both connected with the main machine. The detection method comprises the following steps: a, instrument positioning; b, signal collection; c, signal conversion; d, processing judgment. The infrared alcohol detector has the advantages of being quick in analysis speed, quick and effective, high in response rate, good in operability, high in detection flexibility, long in service life, good in stability, recyclable, economical and practical.

Description

technical field [0001] The invention belongs to the technical field of alcohol detection, in particular to an infrared alcohol detector and a detection method thereof. Background technique [0002] With the rapid development of the automobile industry, the number of traffic accidents caused by drunk driving is increasing day by day, and the harm to people's lives and property is becoming more and more serious. However, detecting whether a driver is drunk and driving can not only effectively control the driver's illegal behavior, but also in traffic accidents. It is one of the important measures of post-accident investigation and evidence collection. To judge whether it is drunk driving, the most ideal method is to check the driver's BAC (Blood Alcohol Concentration), that is, the alcohol concentration in the blood. In the accident scene inspection or the daily traffic inspection of the traffic police, the simplest and most effective solution is to detect the alcohol content...

AI Technical Summary

Problems solved by technology

[0003] The alcohol tester currently used by the traffic police for law enforcement is clumsy and inefficient, and it cannot be used as evidence material due to the technical accuracy

Testing methods such as blood testing, this method is direct and has small error, but this method is expensive, requires a good laboratory environment, takes a long time to detect and needs to draw blood samples, which limits this method due to its low efficiency and high cost The popularization of the breath alcohol test method is fast and flexible, and is suitable for use on the scene of traffic law enforcement. This method is easily affected by the environment, certain drugs and the cooperation degree of the tested person, which greatly reduces the detection efficiency and leads to traffic jams.
