As a leading enterprise in the field of Internet of Vehicles, Longan Tianxia Electronics actively responded to the national economic strategy adjustment and launched ADAS+DMS+DVR three in one AI active safety early warning system products, covering "driver fatigue driving warning", "abnormal driver posture", "dangerous driving behavior", "driver identity verification", "FCW front car collision warning", "LDW lane departure warning" "PCW Pedestrian Collision Warning" and other aspects, through various sensors installed on the vehicle, collect the environmental data inside and outside the vehicle at the first time, and conduct technical processing such as identification, detection and tracking of static and dynamic objects, so that drivers can detect potential dangers in the shortest time and prevent traffic accidents.

The AI active safety early warning system can conduct real-time AI intelligent analysis on the road condition risk information in front of the vehicle and the driver's risk behavior during driving, and give early warning on driving conditions such as too close distance, collision risk, lane departure, etc; At the same time, pay close attention to the driver's physiological fatigue, smoking, making phone calls and other bad driving behaviors, and give an alarm in time.

        At the same time, when risks appear and occur, the system can automatically report the risk alarm, multi angle audio and video evidence and other information to the platform. The risk control agent can intervene in real time according to the situation, identify high-risk risks, and take voice reminder, intercom and other ways to intervene in real time to further correct the driver's behavior and ensure driving safety.

       In order to implement targeted, efficient post event traceability and driver behavior management, the safety management platform of Longan Tianxia Electronics can support multi-dimensional high-definition evidence chain, which is convenient for tracking and tracing various risk events and handling at any time. The platform will also automatically generate weekly, monthly, quarterly risk reports and driver risk portraits, help governments, enterprises, motorcades, insurance companies and other multi-party safety management organizations identify potential risk control weaknesses, and conduct corresponding training and performance management for high-risk drivers and high-frequency risk behaviors, so as to improve bad driving behaviors and overall safety coefficient from the source.

ADAS system functions include：

Lane Departure Warning (LDW)

Consists of camera, sensor and controller

When the lane departure system is turned on, the camera will always collect the identification lines of the driving lane, and obtain the position parameters of the car in the current lane through image processing. When the car is detected to have deviated from the lane, the sensor will timely collect the vehicle data and the driver's operating status, and then the controller will send an alarm signal. The whole process will provide more reaction time for the driver in about 0.5 seconds. However, if the driver turns on the turn signal and changes lanes normally, the lane departure warning system will not give any prompts.

Forward Collision Warning (FCW) 

The system monitors the vehicles ahead at all times through the radar system and camera, judges the distance, direction and relative speed between the vehicle and the vehicle in front, and warns the driver when there is a potential collision danger. The FCW system itself will not take any braking measures to avoid collision or control the vehicle.

Night Vision System (NVS for short)

The system consists of an infrared camera and a light display system on the windshield

It can help drivers perceive the difference of heat through infrared ray at night or in bad weather when their vision is unclear or unclear, distinguish the difference between people, animals, vehicles and the environment, and transform it into an image after processing, so as to clearly present the original unclear objects in front of the driver to ensure driving safety.

Gap Monitoring Warning (HMW)

When the vehicle speed is higher than 30km/h, the time required for the vehicle to drive to the current position of the vehicle ahead will be displayed in real time. When the real-time distance monitoring function finds that the real-time distance between the vehicle and the vehicle ahead (in the same lane) is less than the set distance (0.1-2.5s, in time units), the system will send a warning to the driver.

DSM system functions include：

The functions of DSM system include fatigue driving alarm, distracted driving alarm, smoking alarm, phone call alarm, driver abnormal alarm, etc. These are collectively referred to as driver status monitoring system（Driver State Monitoring）。

The system mostly uses the camera to monitor the driver's face, judge the degree of attention, whether there is any sign of drowsiness, and use the driver's eye opening and closing frequency to identify the safety level, provide appropriate warnings (such as voice warning lights) or assist in actions (such as automatic braking), so as to reduce accidents. 

BSD system functions include：

The system captures the left, right and rear video signals at the same time. Its main function is to sweep the blind area of the rear-view mirror, detect pedestrians in the blind area of the rear-view mirror at the side of the vehicle through the camera, and remind drivers and pedestrians, so as to avoid accidents caused by pedestrians moving to the blind area of the rear-view mirror during driving.
