All-Domain Emergency Intelligent Alert Terminal | Securing the Communication Lifeline in Extreme Scenarios, Safeguarding Every Moment of Emergency Rescue
Sudden natural disasters, damaged base stations, and public network outages are the most fatal communication dilemmas in emergency rescue. Traditional communication equipment relies on terrestrial networks and is highly susceptible to paralysis in extreme environments such as floods, earthquakes, and severe typhoons, resulting in failure to report disaster conditions, issue commands, or advance rescue operations. To solve the "network outage, power outage, road outage" emergency challenges, a new-generation All-Domain Emergency Intelligent Alert Terminal has been launched, integrating multi-modal communication, national cryptography-grade security encryption, intelligent monitoring and broadcasting, and all-weather damage-resistant protection. With technology as its shield, it bridges the "last mile" of emergency communication, providing all-time, all-scenario, high-reliability integrated support for disaster prevention and mitigation, rescue operations, and disaster monitoring.
I. Multi-Network Converged Intelligent Switching, Communication Never Disconnects in Extreme Environments
Communication stability is the core foundation of emergency rescue. This terminal is equipped with a multi-modal converged communication system, breaking the limitations of single communication modes by integrating four communication channels: 4G/5G public network SMS, non-parabolic two-way satellite communication, BeiDou short message, and L-band satellite early warning reception, achieving integrated space-ground and all-domain coverage. Each communication module is physically isolated and supports fully automatic intelligent switching based on the on-site signal environment, with no manual intervention and seamless handover.
When public network signals are normal, the device prioritizes public network transmission for high efficiency and low power consumption. When a disaster causes public network paralysis, it can automatically switch to satellite communication mode within 5 minutes, and immediately switch back to the public network once connectivity is restored, completely resolving communication disconnection issues in extreme scenarios. The device is equipped with a professional Ku-band satellite communication system with a transmit frequency of 14.0–14.5 GHz and receive frequency of 10.7–12.75 GHz. Under harsh conditions, the forward playback channel achieves a bit error rate of ≤1×10⁻⁶ at Es/N0=-8dB, with forward rate ≥100kbps and return transmission rate ≥32kbps. Combined with L-band omnidirectional reception capability of ≤2GHz, it ensures stable transmission of data, voice, and SMS in complex terrain and severe weather. It also supports full-band FM broadcasting from 87.0MHz to 108.0MHz, enabling real-time reception of emergency broadcast information and broadening early warning information acquisition channels.
II. National Cryptography Hardcore Encryption Protection, Building a Solid Barrier for Emergency Information Security
Emergency disaster data and rescue commands are core confidential information, making transmission security critical. The terminal features a built-in hardware-level encryption/decryption chip, employing national commercial cryptography standard algorithms throughout the process to comprehensively safeguard information transmission security: SM4 block cipher algorithm for encrypted data transmission, SM3 message digest algorithm for data verification, and SM2 identity authentication algorithm to prevent unauthorized access. Triple national cryptography protection provides layered defense, effectively intercepting illegal data intrusion, preventing information tampering and leakage, and blocking illegal information transmission, ensuring that all disaster data and dispatch commands transmitted via satellite and public networks remain secure, controllable, authentic, and valid.
The device also features a precise SMS permission control mechanism, supporting SMS and broadcast command transmission only from pre-designated numbers, with automatic interception of messages from unknown numbers, eliminating false disaster information and invalid command interference at the source and ensuring precise and efficient emergency dispatch.
III. Integrated Intelligent Emergency Functions, Empowering Efficient Rescue Operations
The device integrates multiple practical intelligent emergency functions, providing one-stop support for the full rescue workflow including early warning broadcasting, emergency assistance, on-site evidence collection, and disaster reporting. With comprehensive functionality and convenient operation, it adapts to various emergency operation scenarios.
Equipped with a protected SOS one-button alarm device, the button is durable and anti-misoperation, enabling one-press linkage with the digital emergency system to initiate emergency assistance and quickly push location and distress signals. A built-in 3W high-fidelity speaker with AEC echo cancellation algorithm delivers HD two-way communication, ensuring clear intercom and barrier-free communication even in noisy rescue environments. Dual-channel ≥40W high-power amplification broadcasting equipment supports automatic audio conversion and broadcasting of multi-format content including voice, text, SMS, and early warning announcements, precisely delivering emergency command instructions and disaster warning information.
The device features professional audio monitoring and storage functionality with audio sampling rate ≥8K and sensitivity no lower than -30dB/94dB SPL@1 kHz, enabling full-process recording, storage, and real-time playback of broadcast content for traceable and reviewable rescue operations. A built-in HD image acquisition system supports on-demand transmission of 1080P and above HD images and videos, adapting to different network environments to visually present on-site disaster conditions and provide precise visual evidence for command center decision-making. A 4-megapixel HD surveillance camera with resolution ≥2560×1440 and minimum illumination as low as 0.005LUX delivers clear imaging even in no-light environments, supporting 0°–340° horizontal and -5°–105° vertical wide-range monitoring, with built-in motion detection and 128G local storage for all-weather on-site dynamic monitoring.
An innovative emergency WiFi conversion system converts satellite communication signals into local WiFi signals, allowing ordinary smartphones to connect without dedicated equipment. Users can quickly access the disaster reporting page via a dedicated QR code, supporting text, voice, and image multi-format disaster reporting with one-click synchronization to the command center and associated systems, significantly lowering the threshold for disaster reporting. The device is additionally equipped with a red LED safety warning light and white illumination light powered by independent solar supply, serving both on-site warning and emergency lighting needs. A high-precision electronic rain gauge with rainfall intensity measurement range of 0–4mm/min and resolution ≤0.2mm enables precise rainfall monitoring, suitable for flood control and mountain torrent monitoring scenarios.
