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 Instruction Book of RDT-300B Fatigue Early Warning System 2014-T300-GE001 2.

Function instruction 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 3 Instruction Book of RDT-300B Fatigue Early Warning System 2014-T300-GE001 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

<15 15~30 30~50

>50 Sensitivity Stopping working Low Medium 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 4 Instruction Book of RDT-300B Fatigue Early Warning System 2014-T300-GE001 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 three-way switch signal output RDT-300B has 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. 5 Instruction Book of RDT-300B Fatigue Early Warning System 2014-T300-GE001 II.

V. Applicable Vehicle Passenger and cargo transport vehicles, dangerous goods transport vehicles, mining vehicles, taxis and school buses and other vehicles. 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. 12 Instruction Book of RDT-300B Fatigue Early Warning System 2014-T300-GE001 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.
