Problems solved by technology

[0005] Problems in facial image information collection: users are required not to wear sunglasses, because sunglasses (especially polarizers worn by drivers) can filter out most of the infrared rays, ultraviolet rays and reflect visible light; facial image information is used to collect physiological signal, there are also shortcomings such as large amount of data, complicated processing, inconvenient transmission, and easy exposure of the driver's privacy.
[0006] Problems in medical detection of brain waves: data processing is very complicated, it is difficult to use in ordinary cars
[0007] To sum up, the existing devices and methods for judging driver fatigue have the following defects: only a single piece of information is collected as the basis for judging driver fatigue driving, and it is difficult to accurately judge whether the driver is in a fatigue driving state; Information collection or hospital brain wave collection of the driver's physiological data, there are shortcomings such as large amount of data, inconvenient transmission, complex processing, etc.
In the prior art, there is no device and / or method that can timely and accurately judge the driver's fatigue driving state and intervene control

Abstract

The invention discloses a fatigue driving detection control system based on physiological signal collection and a fatigue driving detection control method based on the physiological signal collection. The fatigue driving detection control system comprises a physiological signal collecting device, a communication module, a data processing controller, a vehicle starting circuit control device and / or a management and control center, wherein the physiological signal collecting device comprises a sensor group comprising a noise-bridge myoelectricity sensor and a head brain-electricity sensor, the data processing controller is used for compacting, judging and processing input data, outputting a corresponding control signal and / or comparison result, and is stored with the physiological fatigue data corresponding to the fatigue driving state of the human body; the vehicle starting circuit control device is used for switching on or switching off a vehicle starting circuit according to the received control signal; and the management and control center is used for performing computer prompt or artificial voice prompt to a driver. The physiological data of the driver are collected in real time, transmitted and compared, whether the driver is in the fatigue driving state or not is accurately judged in time, and intervention and control are performed for the vehicle and / or the driver when the driver is in the fatigue driving state, in this way, the happening of traffic accidents is reduced effectively.

Description

technical field [0001] The invention relates to a control system and a control method thereof, in particular to a fatigue driving detection control system and a control method based on physiological signal collection. Background technique [0002] At present, the instruments used in the prior art to prevent driver fatigue driving are mainly divided into the following two categories: [0003] One type is a car-centered fatigue driving detection instrument represented by an automobile manufacturer. It indirectly judges driving conditions by detecting the driving conditions of the car, such as whether it takes a "serpentine" route, whether it is fast or slow, etc. staff fatigue. Apparently, there are many uncertainties in the driver fatigue detection instrument and its judgment method, and the accuracy is relatively low. [0004] The other is driver-centered fatigue driving detection instrument, which mainly includes the following two types: one is to use a camera (or other i...
