Description
Technical field
The utility model system is a kind of fatigue driving monitoring device, especially means a kind of prison for promoting the tired effect of sensing
Survey device.
Background technology
Since vehicle is increased, the opposite chance for causing traffic accident masters that are also more and more, however causing the accident
Because nothing more than being driver's drunk driving, drive over the speed limit or the factors such as physiological problem, wherein physiological problem is emergency situations mostly, can not
Expect and be difficult to avoid that, such as fatigue driving, the influence for traffic safety is quite big, and danger is farther to be more than that other are started
Thing reason.
Recently as the development of Intelligent Transportation System, with every sophisticated technologies sense driver's state of mind or
It avoids the detection technology for driving careless mistake fairly common, in known techniques, probably there is following several ways：
1. as long as vehicle speed per hour is more than 65km/h and continues traveling 15 minutes or more, tired caution system can detect fortune
Make, the driving condition (such as steering wheel rotation, abnormal deflection accelerate ...) that it can drive by lasting detecting carrys out interpretation and drives
Whether the person of sailing is fatigue state；If detecting situation, instrument board can show suggestion rest signal (such as coffee cup), and send out
Caution sound is prompted.
2. driver attention auxiliary system, the function mode of this set system, mainly through the perceptron in steering wheel
The hand motion that driver operates steering wheel is detected, whether analysis driver abnormal steering wheel rotation has occurred, and penetrates
Display screen on instrument board reminds driver to take care with coffee cup.
3. installing one group of infrared ray sensor on the dash panel, infrared ray can be constantly sent out to detect the eyeball of driver
Action, when the eyelid for finding driver has hung down or eyes are just being stared at toward non-track direction, computer will be given and remind,
It such as sends out warning sound and wakes driver up.
4. lane bias alarm system is when driving, run-off-road number is excessive, and system can judge that driver is in fatigue driving
State, meeting display alarm coffee cup icon on Dashboard screen, informs that driver should stop and has a rest.
5. steering angle sensor or the steering of electric powered steering continual analysis driver can be used by driving lethargic sleep detecting system
Behavior, to find the tired pattern of standard；The system can also record any unexpected, tiny go to action.It is aided with others
Parameter (such as travelled when number and the time on the same day), system with regard to can pick out fatigue warning sign.
However, aforesaid way, though the physiology action of driver can be sensed, senses effect, it can be because of everyone physiology
Difference and accurate judgement can not be made, can not still play best sensing efficiency.
Utility model content
The purpose of this utility model is providing a kind of fatigue driving monitoring device, simple in structure, easy to operate, with detecing

Rate Variability, HRV), respiratory rate, the data such as blood pressure, then come via index of the algorithm as assessment driving fatigue
It analyzes and determines and drives current fatigue state.
In order to achieve the above object, the utility model discloses a kind of fatigue driving monitoring devices, it is characterised in that includes:
The detector of one detecting driver's physiological signal, the watchcase for showing screen including a tool and the master control in watchcase
Substrate and the sensor linked with master control substrate are hung on any position of body to wear；
One is interconnected with the detector and receives driver's physiological signal detects high fatigue strength or less than warning to work as
The receiver reminded in time during value, including display, high tone quality horn, microphone, sim card slot and master control substrate, the reception
Device is set in car body.
Wherein, which is the instrument of the sensor or portable detecting physiological data that are worn on any position of body
Device.
Wherein, which is a mobile unit.
Wherein, the mobile unit of the receiver is a built-in or exterior driving computer.
Wherein, the plug-in device which is placed in car body for one.
Wherein, the plug-in device of the receiver for it is wearable call wrist-watch, bracelet, independent plug-in device, driving recorder,
Guiding aircraft, plug-in Vehicular display device or rearview mirror.
Wherein, which further includes a GPS satellite positioning integration module, object wearing device, lithium battery and USB.
Wherein, which is incorporated into and the automatic evil spirit's stop system of vehicle with receiver.
Thereby, the utility model is outer with multi-functional object wearing device (equipment) and vehicle-mounted (BLE gateway) equipment or individual
It can link automatically with it after hang device (BLE gateway) pairing, link and start with object wearing device immediately after car starts
Monitoring in real time drives physiological behavior and collects physiological data blood oxygen, heart rate, heart rate variability amount via object wearing device (equipment)
(HRV), respiratory rate, blood pressure, then via index (HRV of the algorithm as assessment driving fatigue<50ms, milisecond document
On be using 50ms as boundary) drive current fatigue state to analyze and determine, when there is fatigue data, the outer of receiver mounts
It puts or car-mounted computer starts alert news alarm (with vibrating alert), and start notice security personnel system immediately immediately with wearing detector
System, security system start monitoring immediately.
When more than alarm time 5 to 10 seconds, physiological behavior (heart rate, blood oxygen, blood pressure, heart rate variability amount) does not restore mark yet
Accurate value does not do appropriate reaction and mental regulation immediately, third party's security system (saving company, client service center from damage) understand immediately with
Advise By Wire driver (device be all setting force auto-pickup), using as reminding and ensure to avoid fatigue driving behavior.
