A Drunk Driving Prevention System Based on Wireless Sensor Network

Abstract

The invention discloses a system for preventing drunk driving based on a wireless sensor network. The system establishes a local area network inside the car and transmits related instructions through the ZigBee protocol. The alcohol concentration in the air is tested by an alcohol sensor and the pupil and eyeball changes are compared using an image sensor. Judging whether the driver is drinking and driving, and the degree of "drinking and driving", and dealing with the drunk driving driver accordingly, you can lock the engine, ventilate, send text messages, seek a substitute driver, achieve safe travel, and prevent drunk driving behaviors Appear.

Description

Technical field [0001] The invention relates to a drunk driving prevention system based on a wireless sensor network, which belongs to the cross field of sensor technology embedded development and wireless communication. Background technique [0002] The 2008 World Health Organization's accident survey showed that about 50%-60% of traffic accidents are related to drinking and driving, and drinking and driving has been listed as the main cause of death in car accidents. In China, there are tens of thousands of traffic accidents caused by drunk driving every year; and more than 50% of fatal accidents are related to drunk driving. The dangers of drunk driving are shocking, and it has become the number one killer of traffic accidents. ". In August 2010, the Sixteenth Meeting of the Standing Committee of the Eleventh National People's Congress deliberated for the first time the draft of the Criminal Law Amendment (8). Drunk driving will be sentenced. [0003] According to a survey, 40...

[0006] 2) Being told not to drink and drive, but insisting on going his own way without any compulsory measures to deal with it;

[0008] The traditional way of identifying drunk driving in a car is to detect that the alcohol concentration in the air in the car is too high, and judge the driver as "drunk driving". The alcohol concentration is too high, which makes the judgment method misjudgment;

[0009] At the same time, the traditional way to deal with drunk driving is only to judge the driver as "drunk driving", and there is no further effective way to deal with it.

Moreover, the wiring of traditional drunk driving processing devices is complicated, which increases the complexity of motor vehicle design
