Abstract: ［Objective］ Construction management at urban rail transit vehicle bases typically relies on work permission and work closure method to control construction safety. However, there is a lack of real-time protective technologies for monitoring the illegal construction. Unauthorized construction personnel entry into non-construction areas poses safety risks such as personnel electrical hazards and human-vehicle collisions. Therefore, it is crucial to conduct research on construction safety protective technologies to reduce the incidence of on-site accidents. ［Method］ Based on RFID (radio frequency identification) technology and binocular vision personnel identification technology, a system that verifies access permissions and locates individuals in construction areas through real-time analysis of RFID identity information and signal strength is developed. Meanwhile, this information is compared with the number of personnel entering/exiting the construction area identified by binocular vision technology to automatically issue warnings to unauthorized personnel intrusion. ［Result & Conclusion］ Through an in-depth analysis of construction area division methods and construction management processes at urban rail transit vehicle bases, a warning system based on RFID and binocular vision for construction area personnel intrusion is proposed.
