Roadefend Intelligence Technology DT500B Active Safety Intelligent
Control System
System Introduction
RDT500B is an active safety intelligent control system developed on the basis
of the image recognition algorithm, which integrates driver status early-
warning analysis and forward active safety warning with a main function of
safety drive assistant, so as to avoid road accidents caused by poor driver
status or improper operation. As split design is applied in the product,
different camera solutions can be selected according to the vehicle models.
The product can communicate with the platform independently and can also be
used with other on-board terminals through ethernet to provide a complete set
of solutions for vehicle active safety control.
Fully considering the requirements of active safety terminals proposed by JT/T
883, JT/T 26773, JT/T 794, JT/T 1076, TJSATL13-2017 and other standards in
designing the product has not only ensured the product conforming to the
requirement, but also enhanced the stability, compatibility and
maintainability of the system.

Note 1: Since RD-CAM-AD500 and RD-CAM-AD501 have different outlet modes, which can be selected according to different models and different installation methods.
Introduction of system components
Integrating the camera for analyzing driver status, RDT500B is acted as an
operation processing center of the whole system to calculate the high-
definition digital video information input by the forward road surveillance
camera.
RD-CAM-AD500 / RD-CAM-AD501
The RD-CAM-AD500 is an ADAS camera for road ahead, which is targeted road
in front to monitor the road ahead. Video data obtained will be sent to
RDT500B machine for analyzing and processing. With bottom outlet, it’s
generally applicable for large vehicles. While RD-CAM-AD501 is generally
applicable for small passenger cars with top outlet.

Specification and Function
Active safety Function
| Alarm type | Description | Voice prompt |
|---|---|---|
| Fatigue warning (level 1) | When the driver is found to be sleepy, |
exceeding the level-1 warning threshold, an alarm will be raised.
| ****
“Toot~ toot~ toot~”
Fatigue warning (level 2)| When the driver is found to be sleepy, exceeding the level-2 warning threshold, an
alarm will be raised.
| “Toot, toot, toot, toot, attention
please”
Obstruction
| When an obstruction covering the camera for monitoring the driver’s condition over the set
time, an obstruction warning will issued.
| ****
“Dang~dang~”
Leaving the post
| When the driver deviates from the driving position and the driver’s face cannot be detected
by the device, an alarm will be raised.
| ****
“Dang~dang~”
Distraction prompt
| When the driver is distracted from the road ahead, such as looking up, looking down and
looking around, an alarm will be raised.
| “Watch out road conditions ahead”
Smoking| When the driver smokes while driving, an
alarm will be raised.
| “No smoking”
Make a phone call
| When the driver makes a call while driving, an alarm will be raised.| ****
“Drive carefully”
Yawn| When the driver yawns while driving, an alarm
will be raised.
| “You are sleepy.
Take a rest please”
Substitution prompt
| 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.
| ****
“Driver has changed”
safety warning in the forward direction
| Alarm type | Description | Voice prompt |
|---|
Forward collision 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.
|
“Toot, toot, toot, toot, toot~”
Low speed collision warning
| 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.
|
Sharp “Tick, tick, tick”
Excessively-close vehicle distance level
1
| 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.
|
“Ding~”
Excessively closed distance level 2
| 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.
|
“Dingding~”
Lane deviation warning| When the vehicle speed exceeds the set value, and the driver deviates from the lane
unintentionally, an alarm will be raised.
| “Tick, tick, tick, tick, tick, tick, tick,
tick”
Other major function
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.
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 “Ticktick” made
by the device when the calibration is completed.
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. Infor mation acquisition is conducted to the device
through the butted in-vehicle equipment. Meanwhile, information interaction
can be shared between the 4G network and the cloud platform through the in-
vehicle equipment.
Driving video recording
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, It’s support for local video storage and remote playback
download.
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.
Alarm linkage
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.
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” with the device restarting.
Analog image output
Also, real-time analog image output is supported by CVBS, which can be used
for direction calibration during installation, and connected to other
peripherals
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.
WiFi function
The device can be connected with the mobile phone through WiFi hotspot, and
the working condition of the device can be viewed by opening the app of
roadefendroadefend, such as viewing real-time video, parameter adjustment, etc
