The locomotive crew status warning alert system (model Ydvs- 03) is a professional, safe and stable solution for crew status monitoring specifically for the railroad industry. The system is based on image enhancement feature analysis technology, which realizes fatigue monitoring, behavior monitoring, abnormal driving behavior and other status analysis and early warning of locomotive crew, solving the operational safety drawbacks of traditional vehicle video monitoring for crew operation, such as "incomplete control", "lax control" and "big hidden danger", providing data support for crew operation status management and supervision, and ensuring efficient locomotive operation. By creating an early warning alert system to monitor the status of the crew, it can effectively prevent accidents caused by fatigue driving, improve the management level of the crew, enhance the enterprise's safety production management capability and improve the comprehensive operation management level.
