Embodiment

[0039] The system structure of this example is as follows figure 1 As shown, it consists of a heart rate sensor, a signal processing circuit; an alcohol sensor, a signal processing circuit; an infrared camera, an image processing system; a computer control system, a comparison device; and a card reader, GPRS / CDMA interface, and a recorder. The heart rate sensor is installed on the outer ring of the steering wheel, which is convenient for the driver to hold. The collected heart rate data is sent to the computer control system through the signal processing circuit. If a non-contact heart rate acquisition method is used (see Chinese Patent Publication "Measurement Method for Non-Contact Key Physiological Parameters", Publication No. CN101006915A, Publication Date 2007.08.01), the installation position of the heart rate sensor may not be subject to the above restrictions. The alcohol sensor is installed directly in front of the steering wheel to collect the alcohol content of the...

Abstract

The invention relates to a vehicle control technology, in particular to a method and a device to utilize the data of the life activity characteristics of a driver to carry out the monitoring of the state of the driver. The invention aims at overcoming the shortcomings of the prior art that the detection of the monitoring method of the driver is not convenient, the using scope is limited and the monitoring is inadequate, so as to disclose the vehicle driver state monitoring method and the system, further to carry out the identification and monitoring on the driver. The invention carries out the comprehensive processing of various data by collecting the data of the life activity characteristics of the driver, in particular to heart rate, head movement distance and the standard deviation of the changes, and finally accurate judgment is made. The invention can be used for the monitoring of fatigue driving of the driver, driving by another person on behalf of the driver, vehicle anti-theft and so on. The invention is characterized by accurate judgment and convenient usage.

Description

technical field [0001] The invention relates to motor vehicle control technology, in particular to a method and a device for monitoring the state of a driver by using characteristic data of vital activity. Background technique [0002] With the rapid development of the transportation industry, traffic accidents caused by theft of motor vehicles and abnormal driving by drivers are becoming more and more serious. Relevant departments of the state attach great importance to it, and many technologies for driver identification and status monitoring have emerged. . Judging from the existing scientific and technological literature and patents, there are mainly technologies based on image recognition, biometrics and monitoring the driver's state according to the state of the car. Among them, the representative patents are: application number 200410041994.8, published on May 11, 2005, the invention patent application titled "Method and System for Biological Recognition of Driver Fat...
