Description
Technical Field
[0001] The invention relates to the technical field of highway tunnel rescue, and in particular to an intelligent command and dispatch system for emergency rescue in highway tunnels. Background Art
[0002] Tunnel accidents often result in serious casualties and property losses due to their special environment and conditions. In traditional rescue systems, rescue responses are often limited by the lack of understanding of the accident site and environmental conditions, resulting in delayed rescue operations and improper resource allocation. In addition, rescue operations inside tunnels usually require fast and accurate decision support to respond to sudden and changing situations, such as traffic accidents, fires, or leaks of hazardous substances.
[0003] Existing rescue systems often lack effective data integration capabilities and are unable to obtain comprehensive tunnel status information in real time, which limits the ability of the rescue command center to respond quickly in emergency situations. At the same time, the evaluation models in existing technologies often cannot be updated in real time and cannot accurately reflect the current tunnel environment and traffic conditions, further reducing rescue efficiency and resource utilization.
[0004] In addition, the deployment of rescue resources often fails to effectively take into account real-time traffic and environmental changes, resulting in the delay of rescue resources or waste of resources.
