Embodiment Construction

[0044] In the embodiment of the present invention, first, the reflective oximeter sensor is used to collect the blood oxygen saturation of the driver under normal conditions, the blood oxygen saturation threshold is set, and then the blood oxygen saturation of the driver is monitored in real time. Alerts the driver when the saturation falls below the set blood oxygen saturation threshold. Because the reflective oximeter sensor is placed on the steering wheel, the driver will not feel uncomfortable and disgusted, so it is very practical.

[0045] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

Abstract

The invention discloses a method and system for preventing fatigue driving. The method comprises the following steps: acquiring a plurality of groups of oxyhemoglobin saturation original signals of a driver under the normal physical condition; carrying out signal conditioning on the plurality of groups of oxyhemoglobin saturation original signals, and calculating to obtain a plurality of oxyhemoglobin saturations; calculating to obtain the average value of the oxyhemoglobin saturations; setting an oxyhemoglobin saturation threshold value according to the average value of the oxyhemoglobin saturations; acquiring oxyhemoglobin saturation original signals of the driver in real time; and carrying out signal conditioning on the oxyhemoglobin saturation original signals acquired in real time, calculating to obtain the oxyhemoglobin saturations, and warning the driver if the oxyhemoglobin saturations acquired in real time are continuously lower than the first time preset by the oxyhemoglobin saturation threshold value. According to the method and the system provided by the invention, electrode plates are not needed for acquiring the oxyhemoglobin saturation original signals, so that the driver can not have the body discomfort and antipathy, and therefore, the practicability is strong.

Description

technical field [0001] The invention relates to the technical field of vehicle engineering, in particular to a method and system for preventing fatigue driving. Background technique [0002] Fatigue driving is an important cause of traffic accidents. The current method of monitoring the driver's fatigue state mainly monitors the driver's physiological parameters, such as EEG, EKG, EMG, etc., but the measurement needs to be performed on the driver's body or head. If the measuring device is installed outside, it is easy to interfere with the driver's driving, so the driver is often reluctant to use it. [0003] In summary, there are generally problems such as poor practicability in the anti-fatigue driving technology in the prior art. Contents of the invention [0004] The invention provides a method and system for anti-fatigue driving to solve the problem of poor practicability existing in the prior art. [0005] The present invention adopts following technical scheme to ...
