All-Domain Emergency Intelligent Terminal Converged Dispatch Solution

Overview

When typhoons destroy ground base stations, earthquakes sever communication fiber optic cables, and floods submerge critical infrastructure, the first severe challenge facing emergency command is often not insufficient rescue forces, but the "command blind zone" caused by communication interruption. Traditional narrowband radios, standalone satellite phones, and fragmented video systems struggle to rapidly build a wartime command chain integrating voice, data, positioning, and video within "communication islands" where public networks are damaged. The All-Domain Emergency Intelligent Terminal Converged Dispatch Solution deeply integrates satellite call-response terminals, all-domain emergency intelligent terminals, and a backend converged dispatch platform to construct an emergency communication neural hub featuring "space-based interconnection, all-domain access, visualized command, and intelligent collaboration," providing guaranteed communication and efficient decision-making support under extreme conditions of road disruption, power outage, and network failure.

Core Architecture and Key Technologies

The solution revolves around "one network, one terminal, one platform." The one network is a heterogeneous communication access network integrating Tiantong satellite, high-throughput broadband satellite, Mesh ad-hoc networking, and public 4G/5G, ensuring at least one communication link remains available in any environment. The one terminal specifically refers to the satellite call-response terminal and the all-domain emergency intelligent terminal — the former addresses reliable call-response and SMS/voice interoperability under extreme conditions, while the latter integrates active/passive positioning, environmental sensing, broadband video transmission, and group intercom capabilities. The one platform is the converged dispatch and visualized command platform deployed at the rear command center or in the cloud.

Satellite Call-response Terminal: Guaranteed Communication That Never Goes Offline

This terminal operates on the Tiantong satellite network and features a high-gain antenna and extreme environment adaptability. It serves not only as a "one-touch status report" call-response tool for emergency teams, but also undertakes the critical task of bidirectional satellite short-message transmission. When all other communication means fail, field personnel can send precise coordinates, rapid disaster report text, and predefined status codes to the command center via the satellite call-response terminal. The GIS dispatch module of the command platform automatically parses location information and generates dynamic trajectories on the situational map, ensuring at least minute-level text and positioning communication between the front and rear, providing coordinate anchors for precise delivery of subsequent rescue forces.

All-Domain Emergency Intelligent Terminal: Unified Frontline Sensing and Collaboration Node

The all-domain emergency intelligent terminal is a multifunctional integrated device in the hands of field emergency responders. It integrates wideband/narrowband trunking intercom, video capture and backhaul, BeiDou/GPS dual-mode positioning, and toxic/harmful gas detection sensing into a single unit. Through its built-in intelligent routing module, it dynamically selects the optimal backhaul link — prioritizing public 5G networks and seamlessly switching to ad-hoc networking or satellite channels upon degradation. The terminal supports visualized intercom between individual operators and between operators and rear commanders, and can transmit vital signs and environmental parameters in real time, providing data-based evidence for rear teams to assess personnel safety and adjust operational formations.

Converged Dispatch Platform: The Brain for Visualized Command and Intelligent Decision-making

The rear converged dispatch platform is the brain of the entire system, with its core capabilities lying in resource convergence and visualized presentation. Through standard protocols such as SIP/H.323/VoIP, the platform manages and uniformly dispatches all previously independent communication systems, including satellite phones, LTE trunking, HF radios, video conferencing, and video surveillance. The GIS dispatch engine overlays emergency force deployment, disaster impact scope, critical infrastructure distribution, and real-time on-site video on a single map. Commanders can drag-and-drop to establish temporary call groups, push instructions with one click, or directly select areas for intelligent call-response. Voice, video, and data are presented on the same screen, breaking down information silos and enabling cross-department, cross-level collaboration as seamless as face-to-face coordination.

Typical Application Scenarios

Extreme Disasters with Road, Power, and Network Failure: The all-domain emergency intelligent terminal establishes on-site visualized command through satellite links. Advance teams use satellite call-response terminals to report "lifeline" locations and damage assessments, while commanders intuitively grasp the isolated-area situation on the converged dispatch platform and efficiently coordinate air and ground rescue resources.

Provincial/Regional Emergency Response Joint Drills: With three-tier hybrid networking of satellite, ad-hoc, and public networks, multiple provincial teams equipped with all-domain intelligent terminals achieve cross-city, cross-formation collaborative operations through a unified platform. GIS dispatch displays drill progress in real time, and the intelligent assessment system automatically generates effectiveness reports based on terminal-returned data, using drills as training to validate overall emergency communication resilience.

Hazardous Chemical Park Emergency Support: The terminal's built-in gas sensors and video surveillance modules enable real-time backhaul of on-site explosive-limit gas concentrations and infrared images of leak points. The converged dispatch platform automatically triggers audible and visual alarms, delineates electronic fences, and issues evacuation route instructions to explosion-proof intelligent terminals, preventing mass casualties.

Solution Value

The All-Domain Emergency Intelligent Terminal Converged Dispatch Solution reshapes the emergency command model with combat-ready guaranteed communication at its core. First, the combination of satellite call-response and intelligent terminals ensures no communication blind spots exist in any disaster-affected area, meeting the Ministry of Emergency Management's mandatory requirement of "every call answered, every response connected." Second, position reporting, voice calls, video transmission, and instruction reception — tasks that previously required multiple personnel and devices — are consolidated into a single all-domain terminal, significantly reducing individual operator load and operational complexity while enhancing field agility. Third, the backend visualized dispatch platform breaks down information silos, granting commanders a "God's-eye view" that compresses decision-making time from hours to minutes, with critical instructions reaching the frontline directly. Fourth, the solution adopts a layered open architecture that supports integration with e-government, emergency big data, and UAV inspection systems, protecting investments and enabling peacetime-wartime integration with continuous evolution.

Facing increasingly frequent extreme weather events and complex public safety challenges, emergency communication support has risen to become a cornerstone project for digital government and resilient city construction. The All-Domain Emergency Intelligent Terminal Converged Dispatch Solution, with its trinity design of satellite guarantee, all-domain intelligence, and converged dispatch, provides emergency management departments at all levels with modern command tools that enable them to see, connect, and mobilize effectively, building a robust communication lifeline on the front line of protecting people's lives and property.
