Deeply integrate "video surveillance, fire monitoring, access control monitoring, perimeter intrusion monitoring, personnel positioning, and two-ticket operation", and achieve intelligent linkage among various systems. By integrating technologies suchas positioning, virtual reality, image recognition, Internet of Things, and big data analysis, the scattered subsystems are organically interconnected. Under the visual 3D scene monitoring screen, various factory area safety control businesses are comprehensivelyhandled. Based on the 3D model as the spatial foundation, the entire factory area is divided into N operation zones, and the entire operation process is monitored in real time to achieve immediate early warning of various violations during operations.
