(level 1) Fatigue warning

(level 2) Obstruction Leaving the post Distraction prompt Smoking When the driver is found to be sleepy, exceeding the level-1 warning threshold, an alarm will be raised. When the driver is found to be sleepy, exceeding the level-2 warning threshold, an alarm will be raised. When an obstruction covering the camera for monitoring the driver's condition over the set time, an obstruction warning will issued. When the driver deviates from the driving position and the driver's face cannot be detected by the device, an alarm will be raised. When the driver is distracted from the road ahead, such as looking up, looking down and looking around, an alarm will be raised. When the driver smokes while driving, an alarm will be raised.

"Toot~ toot~ toot~"

"Toot, toot, toot, toot, attention please"

"Dang~dang~"

"Dang~dang~"

"Watch out road conditions ahead"

"No smoking"

Make a phone call When the driver makes a call while driving, an alarm will be raised.

"Drive carefully"

Alarm type Description Yawn Substitution prompt When the driver yawns while driving, an alarm will be raised. After the vehicle moves and reaches the set speed, the driver's identity will be monitored. If the driver change is detected, a voice prompt will be made. Voice prompt

"You are sleepy. Take a rest please"

"Driver has changed"

When CAM-ADAS is equipped, the system can achieve active safety warning in the forward direction Alarm type Description Voice prompt Forward collision warning Low speed collision warning Excessively-close vehicle distance level 1 Excessively closed distance level 2 Lane deviation warning When the vehicle speed exceeds the set speed, and the collision time with the preceding vehicle is lower than the safety time threshold, an alarm will be raised. When the vehicle speed is less than the set speed, and the collision time with the preceding vehicle is lower than the safety time threshold, an alarm will be raised. When the vehicle speed exceeds the set value with the distance maintained less than the set minimum level-1 distance, an alarm will be raised. When the vehicle speed exceeds the set value with the distance maintained less than the set minimum level-2 distance, an alarm will be raised. When the vehicle speed exceeds the set value, and the driver deviates from the lane unintentionally, an alarm will be raised.

"Toot, toot, toot, toot, toot~"

Sharp "Tick, tick, tick"

"Ding~"

"Ding ding~"

"Tick, tick, tick, tick, tick, tick, tick, tick"

3.2 Othermajor function 1) Driver identification If the vehicle has just started or stopped for over a certain period of time, a substitution will be triggered. The driver identification function will be triggered if either condition is met. The driver's photo will be captured by the device and uploaded to the cloud platform for analyzing, identifying and processing through the server of the cloud end, so as to compare with the driver information bound in the platform previously. In this way, the driver identity can be determined. 2) Self calibration of driver feature posture When the vehicle speed exceeds the set value after the device starts, the system will enter the self-calibration time of driving posture. Core parameters of the system will be calibrated based on drivers' characteristics and their driving postures in the process. On this basis, posture alarm (incl. looking up, looking down and looking left and right) can be determined. The posture alarm will not be raised until the calibration is completed. The posture alarm can be raised normally after the voice prompt of "Tick tick" made by the device when the calibration is completed. 3) Information acquisition and reporting GPS information and other vehicle data, such as speed, left and right steering as well as braking can be recorded and stored in the device. Moreover, when an alarm is raised, the alarm related information, including alarm time, type, and the name of the video file corresponding to the alarm time will be recorded by the device. Simultaneous recording of two cameras is supported by the device. What's more, time, positioning, speed and other information can be overlaid on the video. Besides, its support for local video storage and remote playback download. 4) Driving video recording 5) Equipment self-test Self-test will be conducted on primary system sensors and components when the device starts or at regular intervals. If any fault occurs, the corresponding indicator on the device will be displayed in red; at the same time, fault information will be sent to the cloud platform. If a HMI display is equipped in the system, fault information can be displayed via the HMI display in the system. Faults contain DSM abnormal operation, ADAS abnormal operation, Ethernet abnormal communication, CAN abnormal communication, serial abnormal communication, and SD card abnormal read/write, etc. When an alarm event is detected, forensic records of pictures and small videos are supported in all channels of the system.And configuration of different alerts pictures, video upload switches are supported by the platform. 6) Alarm linkage 7) System upgrade Upgrading the system through remotely sending an upgrade package through the cloud platform is supported in the system. In the meantime, upgrading through a local SD card is also available. Copy the upgrade package file into the SD card before starting the device operation. The device is upgraded after hearing tickticktick withthe device restarting. Also, real-time analog image output is supported by CVBS, which can be used for direction calibration during 8) Analog image output installation, and connected to other peripherals. 9) Mobile APP linkage The phone network is connected through the WIFI hotspot in the device. Parameter adjustment calibrating and real-time video viewing can be realized through the APP. See the Appendix for the calibration method. 4 User Notes 1.
