The paths in tunnels and pipe galleries are complex, making it impossible to supervise the inspection routes and working status of patrol personnel in real-time. There are many construction workers and outsiders, making it impossible to monitor personnel entering and exiting the tunnel in real-time. Multi-person collaboration data cannot be synchronized in real-time. The work status of tunnel construction personnel cannot be monitored in real-time, leading to slow emergency response times and an inability to complete search and rescue operations promptly. The wide distribution of operation points at the construction site increases the difficulty of safety control.

Locaris Technology uses UWB positioning base stations to achieve full coverage of tunnel positioning signals. Data transmission is carried out through wireless bridges or fiber optic networks to achieve precise 1D/2D positioning, thus determining the moving positions of personnel and vehicles in the tunnel, as well as the operational status of workers and vehicles inside the tunnel.At the same time, video is combined with positioning devices to achieve video tracking and real-time alarm linkage, as well as automatically retrieving surveillance footage when operating in specific areas. In case of danger, the corresponding surveillance footage is immediately retrieved, and positioning and video data are automatically stored.
