The system achieves intelligent safety control for contact network grounding wire operations through ‌remote control, automatic voltage testing and grounding, and real-time status monitoring‌. It supports three levels of electric operation—central, station, and local—enabling remote voltage testing, discharge, and parallel grounding operations at multiple locations. It also provides real-time feedback on the contact network's live status, grounding switch position, and equipment condition. Additionally, it integrates video surveillance, anti-misoperation logic interlocking, and permission management functions to ensure the entire operation process is visible and complies with safety regulations, effectively preventing misoperations and electric shock risks. By replacing the traditional manual process of hanging and removing grounding wires, the system significantly reduces labor input and operational safety risks. It shortens the time for grounding wire operations from 2 hours to less than 5 minutes, greatly improving maintenance efficiency and the standardization level of operation and maintenance management.
