Alarm method and device for preventing fatigue driving of motor vehicle

Abstract

The invention discloses an alarm device for preventing fatigue driving of a motor vehicle. The alarm device for preventing the fatigue driving of the motor vehicle comprises a single chip microcomputer, and an input interface and an output interface of the single chip microcomputer, and is characterized in that the input interface is connected with a fingerprint recognition device, a face and eyes positioning device, a heart rate monitoring device, a skin surface resistance monitoring device and an alcohol detection device respectively; the output interface of the single chip microcomputer is connected with an alarm device, a vehicle control system, a vehicle-mounted terminal, a card reader and a recorder respectively; the fingerprint recognition device, the heart rate monitoring device, the skin surface resistance monitoring device and the alcohol detection device can be arranged in a key, a safety belt or a steering wheel of the vehicle. The alarm device for preventing the fatigue driving of the motor vehicle has the advantages that the heart rate monitoring device and the skin surface resistance monitoring device can monitor the current state of a driver in real time, timely remind a system whether the driver is going to enter a sleepy period and ensure to give out a system prompt or start the alarm device in first time so as to reduce traffic accidents.

Description

technical field [0001] The invention relates to the intersecting technical field of biomedical engineering and mechatronics, in particular to an alarm method and device for preventing fatigue driving of motor vehicles. Background technique [0002] Fatigue driving, speeding, drunk driving, etc. are important causes of traffic accidents, and it is one of people's long-term tasks to prevent traffic accidents caused by these reasons. [0003] In recent years, with the development of computer technology, integrated circuit technology and digital image processing technology, people have developed instruments to monitor the driver's driving state in time and prevent fatigue driving. EEG. Among them, in monitoring the driver's eye state, when the driver's eyelids stop opening and closing, that is, when he feels sleepy, the system or instrument will immediately send out an alarm to wake the driver up and continue to drive normally. The disadvantages of this device are: The driver'...

Problems solved by technology

Among them, in monitoring the driver's eye state, when the driver's eyelids stop opening and closing, that is, when he feels sleepy, the system or instrument will immediately send out an alarm to wake the driver up and continue to drive normally. The disadvantages of this device are: The driver's fatigue warning is late, and when the driver's eyes stop opening and closing, it is already in the sleep period, which is quite unfavorable for driving; in the system or instrument for monitoring the driver's EEG, it is necessary to use a larger and more cumbersome The electroencephalogram connected with the human brain will bring a certain load to the driver's body and affect driving

At the same time, currently developed instruments for preventing fatigue driving mainly use a measurement method. The inherent limitations of the method itself lead to inaccurate evaluation results, and cannot be prepared to judge the driver's state, which may lead to traffic accidents.
