Integrated solution for train intelligent video analysis system

Integrated solution for train intelligent video analysis system

In 2023, Zhongzhicheng Company achieved encouraging results in the research and development of intelligent video analysis for trains.

At present, in the railway market, due to the characteristics of train drivers' work and the rotation system, drivers' sleep is irregular, and some drivers have accumulated fatigue before boarding. Once a driver changes their job or experiences sudden situations while driving under fatigue, their slow thinking and reduced reaction ability prevent them from taking timely and correct actions, leading to the occurrence of driving accidents. Typical operational errors include: 1. Rushing/emitting signals; 2. Not complying with the operating time and speed limit regulations specified in the train timetable; 3. Not handling or mishandling when encountering unclear signal displays or endangering driving and personal safety. To this end, Guangzhou Zhongzhicheng Information Technology Co., Ltd. has conducted a detailed analysis and research on the current demand for intelligent video analysis of trains, and developed a passive vision based intelligent video analysis system for trains to respond to the future development needs of rail companies.
