I. Product Synopsis
RDT-300B is a bran-new driver fatigue surveillance system that gives a
warning of fatigue drive by means of image recognition and driving behavior
analysis to decrease accidents caused by fatigue drive. Furthermore,
RDT-300B is also capable of setting abnormal data and images via 3G
network to an end-user device to avoid occurrence of accidents by
immediately taking effective measures.
1. Value of fatigue warning
Fatigue has long been an inevitable problem that is controlled to an extent
for drivers, for example, when driving two hours at a speed of 100km/h, the
driver has to struggle to stay awake on account of his lower levels
physiological functions followed by inattention. In general, accident rates
are extremely high when the driver drives more than 6 hours a day or is lack
of proper rest, for example, only having a rest of less than four or five hours
last night.
A set of terrible statistics has already been reported, indicating that 72% of
all accidents occur due to drivers themselves and 25~30% thereof are
caused by fatigue drive; that 40% of all serious and fatal accidents are
fatigue related; that 70% of all drivers will fall asleep at the wheel on the
highway.
Therefore, it is a great value to eliminate fatigue at driving for sake of the
drivers, families, companies, as well as the society.

1) Fatigue warning
As driver begin to fall asleep, the warning system will trigger a “wake-up call”
in time and store the image that the driver fall asleep, then controlling other
sleepy reminder accessories (such as vibration cushions, refreshing smell
generator) via configurable output interfaces, and finally can sent fatigue
information and images to managers through the 3G network. Factors

such as weather, light, complexion, clothing, have no impact on fatigue
warning function of this product even glasses the driver wears.
2) Adaptable adjustment of sensitivity
RDT-300B can automatically adjust its early warning sensitivity according to
vehicle speed, the basic logic is that the faster the speed, the higher the
sensitivity: when the vehicle speed is higher than the predetermined
speed of 15Km/h, the early warning function is activated and the sensitivity
is set to "Low"; when the vehicle speed is higher than 30Km/h, the early
warning sensitivity is adjusted to "Medium"; when the vehicle speed is
higher than 50Km/h, the early warning sensitivity is up to "High".
Correspondence relationship between the vehicle speed and the sensitivity
are as follows:
speed /Km/h Sensitivity
<15 Stopping working
15~30 “Low”
30~50 “Medium”
>50 “high”
3) Driver features self-calibration
Starting RDT-300B, the early warning system enters a period of 30-second
self-calibration with the vehicle speed exceeding the predetermined vehicle
speed. During this period, the system core parameters will be calibrated
according to individual characteristics of the driver. After this process, the
system enters a normal operating state. Please keep a normal driving
state when the system is in the normal operating state, and do not simulate
sleepy state.
4) Analog image output
Instruction Book of RDT-300B Fatigue Early Warning System 2014-T300-GE001
5
RDT-300B provides real-time analog image output via PAL (Phase
Alternating Line) system or NTSC (National Television System Committee)
system. The signal can be used to calibrate the orientation of installation,
and can also be connected with almost all the popular Car DVR (Digital
Video Record) on the market to store the video the driver drove.
5) 3G communication
RDT-300B can transmit alarm information and fatigue images data via 3G
communications for easy supervision and management.
6) Input interface
RDT-300B supports two-way switch signal input.
7) Output interface
RDT-300B has three-way switch signal output to control auxiliary
equipments such as vibration cushions and refreshing smell generator
which start to work when the fatigue drive warning is issued.
8) Camera occlusion reminder
Once the camera is deliberately obscured, the system will issue a "ding –
ding–" beeping sound with the vehicle speed exceeding the predetermined
vehicle speed.
9) Warming image can be stored in local
RDT-300B will create a folder with year.month.day in SD card and store the
warming images sorted by type of fatigue warming(asleep, face exception).
The during time can be set by SD card config and default for 10 days.
10) Exchange data with DFSS management platform
RDT-300B can uploads all the status information to DFSS management
platform, supporting for managers to monitor and manage the relating cars;
at the same time,DFSScan sends config file of RDT-300B to RDT-300B in
order to set it`s operating mood.

VI. Friendly Reminder
1. Will you drive when you are fatigue?
Fatigue driving is different from drunk driving, and people always choose to
or have to drive even though they feel fatigue because they claim they are
alert to fatigue or they are in a hurry sometimes. So the inevitable questions
are as follows: The first problem: people will still choose to drive even
though they are fatigue because they have to do so; the second problem:
the driver acclaims they can control the fatigue. When having a sense of
fatigue, they argue that they can eliminate it through conventional methods
such as, having a cup of coffee and other refreshing drinks, smoking,
turning music volume up, opening windows, scratching his head, twisting
his neck.
However, we should accept the fact that fatigue cannot be eliminated by
means of relying on subjective thoughts of the driver with the aid of applying
the above-mentioned methods to avoid falling asleep. Those irritating
behaviors, such as smoking, increase the volume of the radio, drinking
coffee, opening windows cannot actually prevent “drowsiness –induced
substance" from influencing the brain, and conversely, they cause paralysis
of the driver.

Do you know? Drinking excessive coffee can cause insomnia, headaches,
allergies and anxiety.
Do you know? It takes more than 10 minutes for caffeine to get into your
blood system to finally generate a stimulus, so a cup of coffee would not
have such a quick play as required but you have already fallen asleep.
Also, if you have become accustomed to effects of caffeine, stimulating
effects will be weaker.
Do you know? Opening the window and increasing the volume of the radio
can indeed increase your alertness in a short time, but it will not last long.
2. RDT-300B benefits
RDT-300B employs the method of combining the image recognition with the
driving behavior analysis to give a well-intentioned warning when you are
tired and inattentive. Once serious fatigue occurs, the system will give you
a wakeup call in time, which is a critical moment between life and death.
What a critical moment between life and death, seizing this moment, the
wife can give her rushing husband a reminder;
What a critical moment between life and death,
seizing this moment, the driver will not worry about his safety;
What a critical moment between life and death,
seizing this moment, the passenger will not worry about his safety.
Hindsight is not our aim, what is important is to reduce tragedy.
VII. Security Warning
