These measures play a very good deterrent effect and prevent drunk driving behavior to a large extent, but they cannot correct and prevent the occurrence of drunk driving behavior in the first place, and often when violations are detected, tragedy has already occurred.
In addition, road inspection consumes a lot of manpower and material resources, which is not suitable for long-term and daily development, which makes there are certain safety hazards in the process of management and law enforcement

The invention discloses a vehicle-mounted alcohol monitoring device. The device comprises a microcontroller, an alcohol detection module, a locating module, a communication module, a vehicle relay and an external universal I / O (Input / Output), wherein the alcohol detection module, the locating module, the communication module, the vehicle relay and the external universal I / O are respectively connected with the microcontroller. The alcohol detection module comprises an alcohol sensor, an LED (Light-Emitting Diode) lamp connected with the alcohol sensor, a detection warning circuit of the alcohol sensor, an input circuit during active detection and a power source control circuit of the alcohol sensor. The vehicle-mounted alcohol monitoring device has the advantage that managers can monitor normal parameters such as position and speed of a vehicle, and also can monitor an alcohol concentration detection result of the vehicle and real-time alcohol concentration in the vehicle, so that drunk driving is strictly prevented.
Description
technical field [0001] The invention relates to a vehicle-mounted exhalation alcohol monitoring electronic device for monitoring alcohol concentration. Background technique [0002] In recent years, serious traffic accidents caused by drunk driving have occurred in different cities across the country, resulting in huge casualties and losses, and the social impact is very bad. Relevant government departments have attached great importance to this and issued a number of measures to severely crack down on drunk driving. driving behavior. At present, the alcohol testing products used in traffic law enforcement on the market are mainly handheld and stand-alone in terms of technical characteristics, and the main function is detection, which lacks early warning and preventive effects on drunk driving. Restricted by the above-mentioned objective conditions, the current traffic law enforcement department mainly adopts temporary road inspections to conduct spot checks on drivers. Th...
