Internet-of-things system for preventing and monitoring drunk driving

Abstract

The invention discloses a detection method for preventing drunk driving, which comprises the following steps that: a driver enters a vehicle, turns on a power supply of the vehicle, aims at an air sampling unit to blow air, and an air sampling unit transmits acquired alcohol data to an alcohol detection unit; the alcohol detection unit detects the alcohol concentration value in the air through data transmitted by the air sampling unit, related data are transmitted to the single-chip microcomputer central control unit, the single-chip microcomputer central control unit gives an instruction to an alcohol lock microcontroller unit according to the preset alcohol concentration standard, and when a driver enters a vehicle and starts a vehicle power source, the face recognition unit starts to record face recognition of a driver and uploads data to the single-chip microcomputer central control unit. Alcohol detection and face recognition monitoring are carried out on a driver before the vehicle is driven, drunk driving of the driver is prevented, and the driving safety of the vehicle is guaranteed.

Description

technical field [0001] The invention relates to the field of alcohol detection systems, in particular to a detection method for preventing driving after drinking and driving. Background technique [0002] In recent years, with the progress of society, the rapid development of my country's economy and the rapid improvement of people's living standards, there are more and more vehicles on the road. However, traffic accidents caused by drunk driving also occur frequently. Traffic accidents caused by drunk driving are mainly caused by excessive drinking of the driver, which results in excessive alcohol concentration in the human body, paralysis of nerves, slow brain response, uncontrolled limbs and other symptoms. Vehicles can only be checked by way of road inspection afterwards. This method can only be remedial after the event, but cannot be prevented in advance. These unscientific and untimely methods have caused a lot of inconvenience and failed to take precautions. [0003...

AI Technical Summary

Problems solved by technology

Traffic accidents caused by drunk driving are mainly caused by excessive alcohol concentration in the human body caused by the driver's excessive drinking, which paralyzes the nerves, causes the brain to respond slowly, and causes symptoms such as uncontrolled limbs. At present, traffic managers in my country judge whether the driver is drinking alcohol. It can only be inspected by road inspection after the event. This method can only be remedied after the event, but cannot be prevented in advance. These unscientific and untimely methods have caused a lot of inconvenience and failed to prevent them before they happen
