China develops advanced unmanned tunnel rescue system to assist in complex geography and emergency rescue.
The China Aerospace Science and Industry Corporation (CASIC) announced on Friday that it has developed an unmanned tunnel emergency rescue system with its own intellectual property rights.
Because, tunnel rescues present unique challenges compared to highway rescues, such as complex terrain, reduced visibility, lack of satellite signals, limited site access, and inadequate navigation tools, according to CASIC.
Consequently, the researchers addressed key technical hurdles in creating the system, including autonomous navigation in tunnels, radar-based obstacle detection, autonomous route planning, tunnel communication, and ultra-low-altitude firefighting.
Moreover, the system enables autonomous navigation in tunnels without satellite signals, allowing for intelligent detection and accurate location of fire sources and trapped individuals. It is capable of delivering rescue equipment and fire-extinguishing materials precisely, ensuring a rapid response in the event of a fire. This innovation overcomes challenges like the lack of satellite signals and traffic congestion in expressway tunnel fires.
It is important to note that the system has successfully completed trials, including autonomous navigation, obstacle avoidance, and deploying fire-extinguishing grenades, and is expected to be widely applied in various emergency rescue situations, particularly in expressway firefighting.
