- Forest and Grassland Fire Response:
Fire monitoring, on-site firefighting command, and personnel tracking/safety assurance in remote, network-free forest or grassland areas, enabling real-time audio-visual transmission from the fire scene and remote command.
- Underground/Confined Space Operations:
Emergency response and rescue operations in signal-free areas like underground utility tunnels, mines, and tunnels; establishing communication between underground sites and surface command centers via self-organizing networks.
- Emergency Response in Remote Areas:
Handling sudden incidents in areas with weak communication infrastructure (e.g., rural villages or remote mountains), such as workplace safety accidents or public security incidents, facilitating on-site command and coordination with rear-echelon support.
- Large-Scale Field Operation Support:
On-site communication and command dispatch for network-free field activities, such as grid construction, transmission line survey, and large-scale grid disaster drills—enables real-time connectivity between field personnel and command centers.
Real-Time Command Dispatch in Power Grid Emergency Communication
This solution is built on 4G/5G public and private communication networks, with a portable command console serving as the core on-site node. It enables seamless 4G/5G data transmission among various emergency devices, including UAVs, body-worn cameras, portable surveillance units, and individual terminals. The system establishes an integrated emergency command platform featuring “on-site data acquisition – network transmission – cloud-based dispatch – unified management.”
The solution supports unified access and transmission of multi-protocol devices. Through a cloud-based command and dispatch platform, it enables centralized management of all emergency equipment, unified scheduling of audio and video resources, and real-time monitoring of on-site situations. It is also compatible with existing industry software platforms, eliminating “information silos” and enhancing the intelligence, precision, and collaboration of emergency command operations in network-covered environments.
