Problems solved by technology
At present, the exhaled alcohol content detectors used by the traffic police in law enforcement, due to imperfect detection or calibration methods and inconsistent detection or calibration methods in various places, lead to differences in the accuracy of the exhaled alcohol content detectors, so the exhaled alcohol content detectors It can only be used as an auxiliary detection tool, and it cannot be used as evidence material. It needs to go to a medical institution for blood test and evidence collection
As the simplest and most effective tool in accident scene inspection or daily traffic inspection by traffic police, exhaled breath alcohol detector should not only reduce the factors affecting the detection results in verification and calibration, but also simulate the accuracy of the detection instrument. Based on the actual situation of the human body, it is very important to do a good job of transferring the value, but there is no device and method designed for real-time, fast and effective calibration of the alcohol test method or tester in the prior art

The invention discloses a detecting-calibrating device and method of a detector for detecting alcohol content in exhaled gas. The detecting-calibrating device comprises four-channel sampling equipment, heating and heat-preserving equipment and a mobile platform, wherein the four-channel sampling equipment comprises a combined switching device consisting of a six-way valve and a four-way valve, andfour steel bottles for carrying zero grade gas and ethanol gas standard substances in 0.1mg/L, 0.3mg/L and 0.5mg/L of air. By adopting the detecting-calibrating device, the detector of the alcohol content in the exhaled gas can be detected and calibrated rapidly and accurately in real time, continuous switching of the alcohol gas standard substances in the air is realized on the premise of meeting detection sampling standard, the working efficiency is increased, and the working cost is lowered.
Description
technical field [0001] The invention relates to the technical field of verification of gas analyzers, and more specifically, to a verification and calibration device and method for an exhaled breath alcohol content detector. Background technique [0002] With the rapid development of the automobile industry, the traffic accidents caused by drunk driving are increasing day by day. Drunk driving is one of the main causes of road traffic accidents. All countries have strict controls on drunk driving. Detecting whether a driver is drunk and driving can not only effectively control the driver's illegal behavior, but also one of the important measures for investigating and collecting evidence after a traffic accident. The breath alcohol content tester is a tester used to measure the alcohol content in the driver's deep lung exhaled gas. Since there is a certain correspondence between the alcohol content in the exhaled air from the deep lung and the alcohol content in the blood, k...
