Monitoring system capable of preventing drunk driving

Abstract

The invention relates to a monitoring system for preventing drunk driving, which is used for preventing the drunk driving of a driver. The invention includes an air sampling unit, an alcohol detecting unit and a central control unit. The invention is characterized by also including a flow rate detecting unit and a wireless monitoring unit. The air sampling unit collects the air and feeds the air into the flow rate detecting unit and the alcohol detecting unit for detecting the flow rate of air and the alcohol concentration as well as inputting the relevant data into the central control unit and transmitting the data to a monitor or a monitoring system outside a vehicle by the wireless monitoring unit, thus making demands whether leading the vehicle to normally start or forcing the vehicle to stop starting by the central control unit according to the relevant data and the communication between the monitor and the driver. The technical scheme provided by the invention improves the accuracy for detecting the alcohol and increases the identification to the behavior of the drive for escaping detection. The monitoring to the vehicle and the driver of the monitor or the monitoring system outside the vehicle is enhanced by the wireless monitoring system and the mistaken judgment of the system to drunk driving is reduced.

Description

technical field [0001] The invention relates to a preventive monitoring system for vehicles, in particular to a preventive monitoring system for preventing drivers from driving under the influence of alcohol. Background technique [0002] Drunken driving is one of the important causes of traffic accidents, and the harm it causes is self-evident. Traditionally, my country has a long history of "alcohol culture". Generally speaking, alcohol is needed to cheer up the gatherings of relatives and friends. As the saying goes, "no etiquette without alcohol", with the continuous popularization of family cars, drunk driving is also occurring more and more frequently, bringing more and more traffic hazards. [0003] In order to solve the problem of drunk driving from the source, one of the modes adopted in the prior art is to install alcohol test equipment additionally in the driver's cab, and this test equipment is connected with the ignition circuit or device of the car, when the alc...

Problems solved by technology

The third method adopted in the prior art is the technical solution in the patent application "Safe Driving Assistance System and Safe Driving Assistance Device" with the publication number "CN101102923". The safe driving assistance system includes a breath component concentration determination unit, which Detecting the concentration of alcohol and / or drugs contained in the breath exhaled by the driver of the car, and judging the concentration of the alcohol and / or drugs; The prevention unit enables the convex portion of the seat belt to be installed in the concave portion according to the determination result of the breath component concentration determination unit, and when the determination result is that the driver’s alcohol concentration is high, the convex portion of the seat belt cannot be installed in the concave portion, and If the seat belt is not installed correctly, the car cannot be started

[0004] There is a problem in all existing technologies, that is, the accuracy of alcohol detection. When it appears that the passengers drink alcohol or the items they carry contain alcohol, the detection system may make a misjudgment, so that the car cannot be started normally.

On the other hand, although the harm of drunk driving is well known to everyone, many people always take chances in real life. This is also the reason for the high incidence of traffic accidents caused by drunk driving. Therefore, people who want to drive after drinking It is bound to also want to avoid the detection equipment installed in the car, such as allowing others to replace the driver to carry out the detection of alcohol concentration, so as to achieve the purpose of starting the car, and some methods used in the above-mentioned prior art are such as breathing masks ("ZL02276720. 7. Self-locking, alarm and anti-theft devices for drunk driving") have certain problems in safety and sanitation; Driving assistance device"), such biometric unit technology is relatively complicated, the cost is relatively high, and it is not easy to promote and use
