System Introduction

RDT401BU is an active safety intelligent control system developed on the basis of the image recognition algorithm, which integrates driver status early- warning analysis and forwards active safety warning with the main function of safety drive assistant, so as to avoid road accidents caused by poor driver status or improper operation. A the 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 onboard 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 conforms to the requirement but also enhanced the stability, compatibility, and maintainability of the system.

Introduction of system components

1) RDT401BU Integrating the camera for analyzing driver status, RDT401BU 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.
2) CAM-ADAS The CAM-ADAS camera is for the road ahead monitoring. Video data obtained will be sent to RDT401BU machine
for analyzing and processing. 3) CAM-IPC The CAM-IPC is an IP Camera for road vehicle inside monitoring. Video data obtained will be sent to the RDT401BU machine for recording. Real-time video is recorded to the TF card.

Product list

Specification and Function

Alarm type	Description	Voice prompt
Fatigue warning (level I)	When the driver is found to be sleepy, exceeding
the level-I warning threshold, an alarm will be raised.	“Toot— toot— toot-,
Fatigue warning (It: Nei 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 covers the camera for monitoring the driver’s condition over the set time, an obstruction warning will be 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.| “bang—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.| “1)1 IN, c 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”

When CAM-ADAS is equipped, the system can achieve active safety warning in the forward direction

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 I| When the vehicle speed exceeds the set value with the distance maintained less than the set minimum level-I distance, an alarm will be raised.| “Dine
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.| “Ding dine
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 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’s identity can be determined.
Self-calibration of driver features 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.
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.
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 an 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, 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 alert pictures, video upload switches is supported by the platform.
System upgrade
Upgrading the system 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 “tick tick tick” with the device restarting.
Analog image output
Also, the 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.
