A drunk driving detection system and method based on multi-sensor and video recognition technology

Abstract

The invention relates to a drunk driving detection system and method based on multi-sensor and video recognition technology. The system includes: a central processing module, an alcohol sensor module, a signal processing module, a GPS module, a camera module, a voice module, a GSM module, and a display and control module. The face image captured by the camera is used for recognition, and it is judged whether there is a phenomenon that the replacement driver starts the car so as to pass the detection. During the driving process of the car, through the image analysis of the driver during the driving process, combined with multi-sensor alcohol detection, it can be judged whether the driver has drinking behavior. After the drinking behavior is detected, an alarm signal is sent, the car is locked and controlled, a voice prompt is given, and the driver's drinking behavior and current location information are sent to relatives and friends by text message. The invention integrates multi-sensors and video recognition technology to detect driver's drinking behavior, can realize replacement detection and detection of drinking during driving, and improves recognition accuracy.

Description

technical field [0001] The invention belongs to the field of sensor detection and control, and relates to a drunk driving detection system and method based on multi-sensor and video recognition technology. Background technique [0002] In 2007, Volvo proposed the concept of on-board alcohol detection and introduced a technology called "Alcoguard". At present, vehicle-mounted alcohol detection systems mostly use this method to measure alcohol concentration. Its disadvantages are: [0003] By blowing air against the detector, it is impossible to judge whether there is a problem of blowing air by a non-driver; [0004] The accuracy of drunkenness recognition is low, and drunkenness information cannot be provided; [0005] After detecting drunk driving and locking the vehicle, there is a lack of effective ways and methods to provide on-site rescue information. Contents of the invention [0006] In order to overcome the above-mentioned shortcomings in the existing drunk dri...
