Working Principle: 

Detect pupil's changing characteristics, analyse eyes' fatigue condition:

Drivers normally aren't aware of fatigue driving before the actual accident happens. One of the most important functions of driver fatigue alarm system is to let the drivers understand they are actually in fatigue driving and increase their alertness level. Once the drowsiness detection system detects the driver is under fatigue driving, it will send out a sharp and loud sounds alarm immediately to the driver in cab based on pupil detection technology.At the same time, it will transmit the fatigue signal to the gps fleet tracking system, then the manager will know the driver's situation in office and take some actions to avoid the accident happened, in this way, they can realize the better fleet management.

When the fatigue warning appears as mentioned above, the driver should pull over immediately to have a rest to avoid accident. If the driver continues to drive without any rest, the anti sleep alarm mr688 will remind the driver to have a rest with making the sharp and loud sound whenever necessary.

Installation of Driver Fatigue Monitor: 

  1. Put 5 pin signal cable connect with power supply. (Please according to the part of AVL system (GPS) Connection),connect the 5 pin cable of host with 5 pin signal cable. 
  2. The step to install the device on the dashboard is just similar. Install the device on the dashboard right in front of the driver. The degree between the installation location and the driver's normal driving position should be within 20 degree. MR688 can be fixed on uneven surface as long as the camera is trained on the driver's face.  
  3. Tear the protective film from suction cup of bracket, put the host on the holder (If choose simple sticker bracket, please omit this step) Tear red sticker of holder's bottom, put the host on optimal position of dashboard lightly. Train the lens on your face and adjust the position of the lens according to the state of the green light. Do not block the main display parameters of the instrument panel.  
  4. The host connected with bracket, the lens must be installed vertical. Bracket can be adjusting the height from screw on the right side. Bracket has two universal balls, customers can adjust different direction. The lens must be installed vertically. That means the green light and the center of the lens remain in the vertical. Don't press the double-sided adhesive tape too firm at first, so the inappropriate position can be re-adjusted easily.
  5. To test the right installation, sit in the normal position in the car, if the green light of the camera light up is bright or flashing, indicating that the driver has been detected in opening the eyes. The distance from lens to the driver's eyes should be between 60cm-90cm. when the driver are looking at the front and the green light remain bright, indicating that MR688 can detect the driver's eyes better. Adjust the correct position of the camera where the green light can keep on as far as possible. Flashing green light is normal while driver open the eyes, especially for the driver wearing rimmed spectacles. 
  6. The dashboard of truck and bus is low, try to install at higher position before the driver. If you install the device in the side front of the driver, the angle should be not more than 15 degree, the host should not be higher than the driver's eyes and the angle between the installation location and the driver's eyes should not more than 30 degree. 
  7. The distance from lens to the driver's eyes should be between 60cm-90cm. For some cases, such as: under the strong light, or the people with glasses, or the people with little eyes, the distance should be closer between 60cm-70cm. For normal people, the distance is between 70cm to 80cm.
  8. Sit in the normal driving position. If the green light is on or twinkling, indicating that the driver has been detected in opening the eyes. If the green light is still on or flashing when the driver moves a little distance from left to right and down to up, indicating that the installation location is more reasonable. Then you can rest assured a safe driving. Flashing Green light is normal while driver open the eyes, especially for the driver wearing rimmed spectacles. If there is some shielding, the green light will be flashing.

1. Is the infrared light harmful to my eyes and body?

No at all, the average light outlet power is less than 0.2W, and mostly died down when spreading in a 30°angle and meter distance, less than 1/10 of indoor nature light, just because the infrared light can't been seen when mixed with other lights, you don't aware the existing.

2. I'm worry about too many noisy alarms.

Don't worry, the device have 4 level sensitivities, the lowest level mainly alarm for the real sleeping, looking around need 3-4 seconds to trigger the alarm, nobody will do it so long when driving on the highway.

3. If I must drive under fatigue status, is this unit useful?

Yes, some trunk drivers always drive under fatigue status, some people used to dozy when driving in on the highway, or if you have sleepless night but must drive today. MR688 will detect the fatigue driving, giving out alarms in the instant of dozing off to wake you up.

4. Is it difficult to install?

No, it's very easy, just stick the main unit in front of the driver, and connect power from cigarette socket, no need any engineer or garage!

5.Can it connection to the vehicle power supply?

For professional applications such as  vehicles team etc. ,MR688 has a cable for direct connection to the vehicle power supply.

6. Will it influent my sight? Did I need to look at it?

No, it's much smaller than a GPS navigator, and no need you to stare at it, just leave it alone after you have adjusted the angle toward your eyes.  

7. What's your advantage comparing to the other driver fatigue alarm system?

There are 3 kinds of fatigue alarm system on the market:
Nap zipper, it judges the fatigue status only from the driver's nod. But more people don't nod at all when driving sleep.  And some people used to nod when taking or singing. So the accuracy is very low.
Lane Departure Warning system, this system have restrict. If there is no line on the road, it's no use at all. As we know, there is too much road without any line, or only 1 line in the middle, or the line is broken, all of those will influent the accuracy.
In the Straight, when the Lane abnormal, the driver may be have sleep too long to can not be wake up.
Collision Prevention, this kind of products always use image, millimeter waves or laser light to calculate distance between your car and front/back car.
But the driver's reaction time is different, when driver awake and Sleepy. It shall be more alarm when driver awake, or alarm too late when driver in sleepy.
Image detect will be influenced by light and raining weather. Millimeter is too huge size and low accuracy. Laser light will Hurt the other driver's eyes.
And all of those products are detecting the behavior of fatigue, but some of drivers will keep driving in straight line and same speed after dozed off 10-20 seconds, it's very dangerous if there is any overtake, obstacles or passengers. Our product MR688, waking up the driver in the doze off instant,  much more efficient than those products.

8. Why the device don't alarm when I closed my eyes?

There are 3 reasons: 
First, the device need to recognize the driver's face in the first 10-20 seconds after powered on, it can't be triggered in this period.
Second, the device is smart, if you have big body movement, or speaking, or turned you head, it will recognize that you are in sober status and wouldn't give our alarms until 5-7 seconds.
Third, you are too near, far, low or high, means you are not in center of the camera's shot area, please adjust your seat and the direction ball.
 On the other hand, if you have no movement, speaking, driving in a high speak, and your eyelid is lower and lower, it will give out alarms in 2 seconds as long as your eye closed or pupil can't be detected.
