Embodiment 1

[0038] The first Mq-3 alcohol sensor is installed at the left edge of the steering wheel, and the second Mq-3 alcohol sensor is installed at the right edge of the steering wheel, respectively detects the alcohol concentration in the air on the left and right sides of the steering wheel, and displays it in the form of voltage V 1 and V 2 Sent to the Arduino microcontroller, the Arduino microcontroller checks the risk of the driver being in a drunk driving state according to the obtained voltage; in response to the aforementioned risks, the Arduino microcontroller controls the light-emitting diode, the sound alarm, and controls the car starter to turn off through the control relay.

Abstract

The invention provides a device for detecting alcohol states of people on driver and passenger seats. The device comprises a first alcohol sensor, a second alcohol sensor, a signal processing module and an alarm module. The first alcohol sensor is mounted at the left edge of a steering wheel and used for detecting the concentration of alcohol in air on the left side of the steering wheel and sending the acquired alcohol concentration information to the signal processing module. The second alcohol sensor is mounted at the right edge of the steering wheel and used for detecting the concentrationof alcohol in air on the right side of the steering wheel and sending the acquired alcohol concentration information to the signal processing module. The signal processing module checks risks of a driver in a drunk-driving state according to the acquired alcohol concentration information and responses to the risks to control the alarm module to alarm and control an automobile engine to shut down.The device has advantages that the alcohol states of people on the driver and passenger seats can be distinguished, timely warning and controlling of a vehicle can be realized, drunk driving is effectively avoided, and accordingly traffic safety is remarkably improved.

Description

technical field [0001] The invention relates to the technical field of active traffic safety, in particular to a device for detecting the drinking state of the main and co-driver seats. Background technique [0002] Statistics from the Traffic Management Bureau of the Ministry of Public Security in 2016 show that drunk driving is the third leading cause of fatal accidents, seriously endangering traffic safety. "Criminal Law Amendment (VIII)" and "People's Republic of China Road Traffic Safety Law Amendment" make drunk driving a crime and drink driving an illegal act. According to the "Threshold and Inspection of Blood and Breath Alcohol Concentration of Vehicle Drivers" issued by the State Administration of Quality Supervision, Inspection and Quarantine, drinking and driving refers to the vehicle driver whose blood alcohol concentration is greater than or equal to 20mg / 100ml and less than 80mg / 100ml. Drunk driving refers to the driving behavior in which the alcohol concentr...
