Wireless sensing network-based drunk driving prevention system

Abstract

The invention discloses a wireless sensing network-based drunk driving prevention system. According to the system, a local area network is established in a vehicle; related instructions can be transmitted through a ZigBee protocol; alcohol concentration in the air can be tested through an alcohol sensor, and pupils and changes of eye balls are detected through an image sensor, and therefore, whether a driver performs drunk driving can be judged, and the degree of drunk driving can be also judged, and corresponding measures can be taken for the driver who performs drunk driving, for example, an engine can be locked, ventilation and air change can be performed, and short massages can be sent, and a replacer for the drunk driver can be searched; and therefore, safe travel can be realized, and drunk driving behaviors can be prevented.

Description

technical field [0001] The invention relates to a drinking-driving prevention system based on a wireless sensor network, which belongs to the intersecting field of sensor technology embedded development and wireless communication. Background technique [0002] The World Health Organization accident survey in 2008 shows that about 50%-60% of traffic accidents are related to drunk driving, and drunk driving has been listed as the main cause of death in traffic accidents. In China, there are tens of thousands of traffic accidents caused by drunk driving every year; more than 50% of the accidents that cause death are related to drunk driving. The harm of drunk driving is shocking and has become the number one "killer" of traffic accidents. ". In August 2010, the 16th meeting of the Standing Committee of the 11th National People's Congress deliberated the Criminal Law Amendment (8) draft for the first time, and drunk driving would be sentenced. [0003] According to the survey,...

Problems solved by technology

[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
