2.1.1 DMS Safe Operation System Upgrade DMS (Driver Monitor System) is an abbreviation for Driver Monitoring System, which refers to an information technology system that continuously monitors the driver's fatigue status and dangerous driving behaviors during vehicle operation. Upon detecting driver fatigue, yawning, squinting, or other incorrect driving states, the DMS system will promptly analyze these behaviors and provide audible and visual alerts, serving to warn the driver and correct incorrect driving behaviors. DMS is generally divided into active DMS and passive DMS. Passive DMS judges the driver's state based on steering wheel turns and driving trajectory characteristics. Active DMS systems typically use cameras and near-infrared technology to detect driver status from eyelid closure, blinking, gaze direction, yawning, and head movements. This system adopts active DMS. The schematic diagram for existing excavator modification is as follows:

 High-Precision Positioning Product Features:

Gyro Drift: Eliminates drift to obtain high-precision attitude and heading information.
Acceleration Noise: Eliminates vibration acceleration to obtain high-precision speed.
Zero-Velocity Update: Zero-velocity update algorithm prevents navigation drift.
Software Algorithm: Based on the Extended Kalman Filter (EKF) algorithm model.
Intelligent Recognition: Identifies and isolates data with significant errors.
Eliminates Odometer Reliance: Pure inertial navigation achieves high-precision positioning.
Navigation Technology: Autonomous switching between integrated navigation and pure inertial navigation.
Driving Behavior: Analysis of harsh acceleration, harsh braking, sudden lane changes, and sharp turns. The objectives achieved after the upgrade are as follows:
Implement DMS warnings: e.g., fatigue driving, distraction warnings.
Achieve real-time video recording during excavator operation (front, rear, left, and right sides), configured with two 256GB high-capacity SD cards to ensure long-term data storage, with loop recording support.
4G real-time monitoring of each vehicle's working status, allowing for constant tracking of vehicle location and operational status, with centralized management of all vehicles via a unified management platform.
The recorder also features WiFi communication, supporting data upload and backup to a central storage server at any time within WiFi-covered work areas.
The right and rear cameras also feature BSD (Blind Spot Detection) functionality, accurately identifying pedestrians and non-motorized vehicles within the blind spots in front of and behind the vehicle during operation. When a potential danger is detected, the system promptly issues an alert via an intelligent audible and visual alarm to prevent accidents.
