Drunk driving early warning detection system and method based on steering wheel

Abstract

The invention relates to a drunk driving early warning detection system. The system comprises a steering wheel, a plurality of detection terminals and a control mechanism, the detection terminals areembedded in the rim of the steering wheel around the axis of the steering wheel, through holes are formed in the rim, corresponding to the detection terminals, of the steering wheel, the detection terminals are embedded in the through holes, and the detection terminals are electrically connected with the control mechanism. The control mechanism is embedded in a hub of the steering wheel. A use method comprises the four steps of equipment assembly, software platform construction, detection judgment and drunk driving treatment. On one hand, control operation is simple and easy to implement, universality is good, the requirements of operation of various vehicles can be effectively met, installation and positioning stability is good, the space in the vehicle is not occupied, and meanwhile theview of a driver cannot be disturbed. On the other hand, detection and early warning are comprehensive, and the drunk driving state of the driver can be evaluated and early warned from multiple angles, so that the accuracy and reliability of drunk driving detection and early warning are greatly improved, and the driving safety can be greatly improved.

Description

technical field [0001] The invention relates to a steering wheel-based drunk driving warning detection system and method, belonging to the technical field of traffic monitoring. Background technique [0002] In the activities of driving vehicles, it happens from time to time for drivers to drive after drinking alcohol, which leads to an increase in the risk of traffic accidents and seriously affects driving safety. To solve this problem, it is currently mainly through external detection equipment, such as traffic police and other staff. The hand-held alcohol concentration detection equipment used to detect the driver's drinking status, although to a certain extent meets the needs of the detection and investigation of drunk driving behavior, but on the one hand, the detection operation is extremely one-sided and cannot achieve comprehensive real-time monitoring. ; On the other hand, the detection activities are all passive detection, and it is impossible to detect and stop th...

[0002] In the activities of driving vehicles, it happens from time to time for drivers to drive after drinking alcohol, which leads to an increase in the risk of traffic accidents and seriously affects driving safety. To solve this problem, it is currently mainly through external detection equipment, such as traffic police and other staff. The hand-held alcohol concentration detection equipment used to detect the driver's drinking status, although to a certain extent meets the needs of the detection and investigation of drunk driving behavior, but on the one hand, the detection operation is extremely one-sided and cannot achieve comprehensive real-time monitoring. ; On the other hand, the detection activities are all passive detection, and it is impossible to detect and stop them in a timely and effective manner when the driver's drinking and driving behavior occurs, thereby increasing the risk of drunk driving.

[0003] In response to this problem, a variety of vehicle-based drunk driving detection systems or methods have been developed, such as "A sensor and machine vision-based drunk driving detection method and system" with the patent application number "201910447744.0", and the application number "201910447744.0" 201810080047.1" and other technical solutions and methods such as "drink driving detection device, smart car and its prevention method" can achieve and detect drunk driving behavior to a certain extent, but in the detection process, the current traditional detection methods and equipment Alcohol sensors and heart rate sensors scattered in the car are often used to detect drunk driving, which leads to complex composition and operation of the detection system, which has a great impact on the structure and performance of the vehicle; on the other hand, traditional detection The detection method of the method and equipment is single, resulting in relatively poor detection accuracy, and it is difficult to effectively meet the needs of high-precision drunk driving detection operations
