Description
Technical Field
The present invention relates to a driver behavior detection system, and more particularly, to a driver driving fitness detection and behavior identification system.
Background
The number of motor vehicles in China is greatly increased, and traffic accidents become an important factor for endangering public safety. The accident causes comprise insufficient driving qualification, overspeed, drunk driving, fatigue driving, blind driving and the like of a driver.
Since the traffic regulations become strict in 1 st 2013 and 1 st, drunk driving, red light running and other traffic violations have been greatly reduced, but at the same time, some people have been challenged by careless violations, although some provinces (autonomous areas and straight jurisdictions) are over-strict, such as inner mongolia (from 1 st 2013, 3 rd), the inner mongolia autonomous areas have begun to count part of "subjective malicious and intentional" traffic violations into citizen personal honest files and hook with personal credit, insurance, professional admittance and the like), and the rationality of law enforcement has been strengthened by referencing the subjective intentional behavior identification method in the criminal law, but the lack of relevant identification technical means has led to very slow progress in this respect.
The statistical data of traffic control departments in recent years show that the amplification of the driver license is far larger than that of the purchasing vehicle, and a plurality of people do not start the vehicle at all after taking the driver license into account, so that the traditional method for judging the qualification of the driver according to the driving age still has a certain loophole.
Since traffic regulations become strict, there are more license points for buying and selling, and no effective regulatory measures are currently available. In the actual vehicle use process, the same vehicle often appears, and occasionally different drivers drive (including drunk driving), and aiming at the situations, no system record is made for when and what drivers drive the vehicle, and if traffic accidents or other related problems appear, the responsibility is inconvenient to follow.
At present, the traditional automobile data recorder sold in the market in China only can provide a video information recording function, a supervision department does not have strict examination on whether a driver drives with overspeed wine, how long the driver drives, whether the driver has a rest after driving for a certain time or not, and the like, and the automobile data recorder of the European part of countries (such as Germany) has strict examination on part of information mentioned above, and once a certain index is unqualified, strict punishment is carried out, so that supervision force and measures have a very deterrent force, the driver of the passenger car can voluntarily observe traffic rules, reduce phenomena such as overspeed drunk driving and the like, and have a rest on time.
The criminal law is written with ' drunk driving ' additionally arranged in the ' dangerous driving crime ' of the modification act (eight) of the people's republic of China. The research shows that the larger the law enforcement and the punishment strength are, the larger the probability that a driver is legal to drive is, drunk driving is prevented, and the punishment strength is superior to the execution strength.
The fatigue driving objective detection method comprises the measurement methods of electroencephalogram, electrooculogram, electromyogram, respiratory airflow, respiratory effect, temperature when arterial blood oxygen is saturated, electrocardiograph and the like. Although these methods are relatively accurate, they make complex instrumentation difficult to install because they typically measure either before or after driving, either early or late, rather than in real time, with limited space in the cab. The sixty-second rule of the implementation of the road traffic safety law specifies that the fatigue driving means that the motor vehicle is continuously driven for more than 4 hours without stopping for rest or for less than 20 minutes, or for more than 8 hours per day, and it is necessary to formulate a detection rule for the fatigue driving rule specified by the current traffic law.
The existing researches of alcohol detection, fatigue driving detection, face recognition and the like are mainly solution to a single problem explored from the technical principle point of view, but because the driver and the driving behavior are not effectively bound, a certain blind area exists during accident responsibility. The design utilizes the electronic driver license based on the non-contact IC card to determine the identity of the driver through systematic integrated design, and can effectively solve the problems by combining various sensors and timers to detect and record the driving condition.

Before the driving process, the invention mainly uses the card slot type device of the non-contact IC card read-write module 2 and the built-in detection circuit to accommodate and judge the situation of the IC card type driver license, uses the built-in card read-write module to read the driver information, judges whether the driver information accords with the quasi-driving vehicle type, writes the driving behavior when in abnormal behavior and stopping flameout, and uses the alarm module 8 to carry out acousto-optic warning. After the information login of the driver is successfully completed, the driver needs to blow air to the alcohol concentration detection module 3 to judge and identify the subjective behavior of the driver, the result is analyzed and judged by the alarm module 8, if the result is judged to be qualified, an allowable signal is sent to the automobile ignition unit by the data processing module 1 through the CAN bus, namely the automobile is allowed to start, otherwise, the automobile is not started, the audible and visual alarm is carried out by the alarm module 8, and the mark and the detection time that the previous alcohol detection fails CAN be recorded in the IC card. If the alcohol detection determination passes after the driver is replaced (i.e., the IC card is replaced) or after the interval of 24 hours, normal start-up can be performed.
In the driving process, the invention mainly performs fatigue detection and visual angle attention detection. The former mainly records the running time of the current driver through the fatigue detection module 4, the result is judged by combining the previous running time and the stopping time read from the non-contact IC card read-write module 2 through the alarm module 8, and the warning with different degrees is carried out according to the fatigue judgment result; the latter mainly carries out image recognition to the current driver head visual angle through the camera and the built-in system of the visual angle attention detection module 5, and the result is judged through the alarm module 8, and the attention objects of the driver and the attention time abnormal degree are warned to different degrees according to the driver head visual angle.
The automobile black box module 7 of the invention can store driving information of a vehicle within two years, also supports the automatic uploading of encrypted current driver information, driving vehicle information and driving license integral information of the previous year after detecting specific signals of a gas station and a highway entrance through the vehicle-mounted information uploading device 9, can further verify whether the identity of the driver escapes from a criminal, and can provide possibility for a more diversified traffic violation processing mode, such as: the method can determine whether a driver can get on the expressway according to the integral of the driving license in the previous year, the driver can get on the expressway when the previous year is buckled for 8 minutes, the driver can not get on the expressway when the previous year is buckled for 10 minutes, the driver can not get on the expressway when the previous year is buckled for 12 minutes, and the driver can not get on the expressway when the current year is buckled for all the year.
The data acquisition interface 11 of the invention is used for acquiring driving time, drivers (driving license numbers) and driving state data (including data of fatigue driving detection and visual angle attention detection abnormality or not) stored in the automobile black box when accident occurs or the automobile annual inspection, and provides reference for law enforcement departments.
