A safe driving system and method for preventing drunk driving and fatigue driving

Abstract

The invention discloses a safe driving system and method capable of preventing drunk driving and fatigue driving. The safe driving system comprises an alcohol tester, a microprocessor, a camera and an after-locking relay. The alcohol tester is used for sending a camera infrared ray instruction to the microprocessor, testing the alcohol concentration of a driver at the same time, displaying the tested alcohol concentration test value and sending the tested alcohol concentration test value to the microprocessor. The camera is used for starting shooting video under the control of the microprocessor and transmitting the shot camera video to the microprocessor. The microprocessor is used for obtaining the judgment result that whether drunk driving exists, obtaining the identification results that whether the installation direction of the microprocessor is changed, whether the driver is substituted and whether fatigue driving exists and sending an infrared signal to the after-locking relay. The after-locking relay is used for being controlled to be on and off according to the infrared signal. According to the safe driving system and method capable of preventing drunk driving and fatigue driving, whether the driver has drunk driving and fatigue driving can be judged, the phenomena of false blowing, cheating and substitution of the driver in the midway are avoided, and the practicability is high.

Description

technical field [0001] The invention relates to the technical field of automobile safety driving, in particular to a safety driving system and method for preventing drunk driving and fatigue driving. Background technique [0002] One of the reasons why safety accidents often occur when drivers are tired or drunk driving. Driving fatigue and drunk driving will affect the driver's attention, feeling, perception, thinking, judgment and movement, etc., resulting in inattention, decreased judgment ability, and even trance or instant memory loss, operation pause or time correction Improper and other unsafe factors can easily lead to road traffic accidents. Therefore, it is strictly forbidden to drive a vehicle when fatigued or drunk. [0003] At present, there are many methods and technologies to prevent fatigue or drunk driving. For example, some methods simultaneously detect the driver’s grip on the steering wheel, the steering wheel’s angle of rotation, the driver’s skin curr...

Problems solved by technology

[0003] At present, there are many methods and technologies to prevent fatigue or drunk driving. For example, some methods simultaneously detect the driver’s grip on the steering wheel, the steering wheel’s angle of rotation, the driver’s skin current, the driver’s breathing depth and frequency, and the depth of the accelerator. Judging by the data, the device designed by this method has complex structure and high price

At present, the technology for detecting drunk driving on the market is mainly based on alcohol testing. Alcohol testing can only determine whether the person who blows on the device has drunk alcohol, but cannot judge the driver’s identity information, so if the driver asks someone else to blow for him , the drunk driver can cheat, or judge whether someone is drinking through the sensor, but if the driver himself has not drunk and the person next to him has drunk a lot, it may cause a misjudgment. Neither can be used as accurate evidence to correctly judge and punish drunk driving
