The invention discloses an expiration alcohol tester and an alcohol testing method.The tester comprises a microprocessor, a display screen, a wireless communication module and an infrared detecting device.The infrared detecting device comprises a driving circuit, a gas chamber and a signal processing circuit.An infrared light source and an infrared detector are arranged at the two ends of the gas chamber respectively.A gas inlet and a gas outlet are further formed in the gas chamber.A fan is arranged on the gas outlet, and the driving circuit is electrically connected with the infrared light source.The infrared detector is electrically connected with the input end of the signal processing circuit.The microprocessor is electrically connected with the display screen, the wireless communication module, the control end of the driving circuit, the output end of the signal processing circuit and the fan.According to the expiration alcohol tester and the alcohol testing method, the alcohol concentration of gas is detected in an infrared mode, connection testing can be carried out, a testing result curve is accurately recorded, cost is low, and the detecting efficiency is high.
Description
technical field [0001] The invention relates to the technical field of alcohol testing, in particular to a breath alcohol tester and an alcohol testing method. 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 (BloodAlcoholConcentration), 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 in the dr...
