Driver fatigue monitor with signal output 45km/h start-up speed

Description

Driver fatigue is one of the leading causes of traffic accidents. LS-803 presents a real-time non-intrusive fatigue monitoring system which exploits the driver's facial expression to detect and alert fatigued drivers. The presented approach adopts the Viola-Jones classifier to detect the driver's facial features. The correlation coefficient template matching method is then applied to derive the state of each feature on a frame by frame basis. A Support Vector Machine (SVM) is finally integrated within the system to classify the facial appearance as either fatigued or otherwise. Using this simple and cheap implementation, the overall system achieved an accuracy of 95.2%, outperforming other developed systems employing expensive hardware to reach the same objective.

I/O and RS232 output optional:

I/O output is only a high/low voltage output, you can get only the alarm signal,the connection is easy. The default setting is high resistance status under normal status, low voltage output when triggered.

RS232 output has alarm signal and picture output, thus you can get the driver's face picture in the center, it need to integrate to the GPS system via protocol.

Power input and output

1. Input: 9-36V, LS803 is suitable for both 12V and 24V vehicle, and have good high voltage protection.

FAQ

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 much noisy alarms.

Don’t worry, the device have have speed limit switch, if the speed less than 45km/h, the alarm never been triggered.

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. LS803’s main target is not to detect the fatigue

driving, but the instant of dozing off, giving out alarms in that instant to wake you up.

4. 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 some people don’t nod at all when sleeping, and some people used to nod when taking or singing, 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.

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 image will be influent by light and raining weather, millimeter is too expensive and huge size, laser light will kill 10,000 pieces of your retina cells if scan 30 times/second.

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 LS801, waking up the driver in the doze off instant, much more efficient than those products.

5. 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!

6. Will it influent my sight?

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

It have 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.

8. Why the device not as sensitive as the beginning?

The lens is dirty, please use cotton bud to clear it, if necessary, use some alcohol.

9. It just don’t work at all, what’s the problem?

The system require 12V power and instant electric current 400-500mA, please check your power supply, if the voltage is low, or electric current is not enough, the device may have green light on, but not alarm.

Leisure Auto Security Equipments Ltd, established in 2009, is a factory dedicate in car safety products, especially driver fatigue alarm system. the new products driver fatigue alarm is a fruit of our 8 years' research and development, it is different from any other kind of system on the market, it is the best way to monitor the driver's status.

It adopted the most advanced non-contact infrared camera to capture human eyelid and retina status,( in general, before entering drowsy driving status, human retina was less and less sensitive to the light outside), analyzes the driver’s fatigue status according to PERCLOS method, and give out voice alarm before the driver falling asleep.

It can also detect the driver’s distraction and give out voice reminders to prevent accidents, such as talking with back passengers, adjusting audio, or operating navigator, pick up thing from the ground and so on.
