All-domain Emergency Smart-link Terminal (Satellite Call-out Terminal)

I. Product Overview

The All-domain Emergency Smart-link Terminal (Satellite Call-out Terminal) is an integrated emergency intelligent terminal launched by Beijing Raytrans Digital Technology Co., Ltd. for the emergency command and dispatch communication field. The product integrates multiple capabilities including satellite communication, voice dispatch, video backhaul, GIS positioning, and broadcast/intercom. Under extreme conditions such as public network interruption or communication blind zones, it relies on satellite links to achieve a closed-loop emergency assurance of "call-out, positioning, reporting, and dispatch," making it the core terminal equipment for building an all-domain coverage, converged and linked emergency command & dispatch system.

The terminal supports converged access and automatic switching between satellite networks and terrestrial public/private networks. Working with the converged dispatch platform and visualized GIS dispatch console, it meets the communication assurance requirements of emergency command & dispatch, disaster prevention and mitigation, forest fire prevention, mine rescue, power line inspection, border patrol, and other scenarios.

II. Product Features

• Satellite Call-out: One-key call-out, supporting satellite voice, short message, and location information reporting, with uninterrupted communication in blind zones;

• All-domain Smart-link: Multi-network convergence of satellite/public/private networks with automatic optimal switching for seamless all-domain coverage;

• Emergency Intelligence: IP67-rated rugged design, wide-temperature operation, built-in high-capacity lithium battery, portable and reliable;

• Converged Dispatch: Deeply integrated with the converged communication platform, supporting dispatch services such as emergency call, barge-in, forced release, monitor, call pickup, and broadcast/intercom;

• Visualized Dispatch: GPS/BeiDou dual-mode positioning, real-time terminal location display on GIS map, supporting circle-select calling and track playback;

• Multi-service Access: Built-in Ethernet and RS232/RS485 data interfaces, supporting concurrent transmission of voice, data, video, and other services;

• Secure and Reliable: Supports encrypted communication and dual-machine hot standby, meeting the security requirements of private network communication.

III. Core Functions

• Satellite Communication: Leveraging Tiantong/BeiDou satellite networks to provide voice, short message, and location reporting services, ensuring emergency communication during public network interruption;

• Emergency Call-out: One-key initiation of call-out requests with real-time response from the dispatch console, supporting group call, broadcast call, and emergency call;

• Voice Dispatch: Supports dispatch services such as point-to-point call, group call, broadcast, intercom, and conference call, enabling unified command in coordination with the dispatch console;

• Video Backhaul: Supports external cameras/pan-tilt-zoom cameras to transmit on-site video in real time to the command center;

• GIS Visualized Dispatch: Real-time terminal location mapping, supporting map circle-select, area calling, and track playback for "visible and deployable" operations;

• Recording and Traceability: Full retention of dispatch recordings, supporting post-event review and assessment analysis;

• Multi-network Convergence: Intelligent switching among satellite, 4G/5G public network, and wireless private network, with automatic link failover.

V. System Networking and Converged Dispatch

The All-domain Emergency Smart-link Terminal accesses the converged dispatch platform via satellite links or terrestrial networks, forming an integrated emergency command & dispatch network together with the command & dispatch system, converged communication gateway, and visualized GIS dispatch console:

• Terminal Layer: All-domain Emergency Smart-link Terminals, Satellite Call-out Terminals, Emergency Intelligent Terminals, and other front-end equipment;

• Transport Layer: Multi-network converged transmission via satellite links, 4G/5G public networks, wireless private networks, and optical fiber private networks;

• Platform Layer: Converged dispatch platform (softswitch/IPPBX) and converged communication gateway, enabling unified dispatch of voice, data, and video services;

• Command Layer: Visualized GIS dispatch console and dispatch console terminals, enabling map-based dispatch, voice command, and situational awareness presentation.

The platform supports dual-machine hot standby deployment to ensure 7×24 uninterrupted dispatch services; encrypted communication is adopted between terminals and the platform to ensure private network communication security.
