Communication in Complex Environments
In underground mines, deep within high-rise buildings, inside tunnels, at large petrochemical facilities, and at disaster‑response sites, traditional public‑network communications often collapse due to physical obstructions, multipath effects, electromagnetic interference, or damage to infrastructure. In these “communication孤岛,” even slight delays or interruptions can pose an immediate threat to life and safety. Leveraging its independently developed multi‑network convergence technology, Zhengze Technology has introduced a comprehensive emergency‑communication solution for complex environments. Moving away from reliance on a single base station, we employ a three‑dimensional architecture that integrates MESH self‑organizing networks, 4G/5G public networks, and wired relay links. By deeply integrating core devices—such as firefighter distress beacons, smart air‑supplied respirators, bone‑conduction communication terminals, and communication‑enabled rescue lighting cords—we have built a decentralized, self‑healing, highly secure broadband wireless private network capable of operating in extreme, dynamic conditions characterized by no public coverage, weak signals, or severe interference. This ensures the real‑time, reliable transmission of voice, high‑definition video, precise positioning, and sensor data.
II. Technical Solution Architecture: Three-Tier Convergence, Full-Region Connectivity
This solution centers on a product matrix, establishing an end-to-end information loop that integrates “individual operators – field operations – back office.”
1. Front-end Perception Layer: Intelligent Individual Soldier Communication Terminal Cluster
RHJ680T Firefighter Personal Alarm (Search-and-Rescue Model):
Core features: Integrated GPS/BeiDou dual-mode positioning, altitude measurement, and ambient temperature monitoring (with an alarm for temperatures exceeding 80°C).
Self-organizing network capability: Equipped with adaptive relay functionality, enabling line-of-sight communication between individual units over distances of ≥1,500 meters, and automatically determining search-and-rescue direction and floor levels.
Peripheral Device Integration: Supports connection to heart-rate wristbands, toxic gas detectors, and smart air-supply respirators, enabling real-time collection of vital signs.
ZXF-TC30/ZXF-TC10 Full-Duplex Group Communication System:
Decentralized communication: Supports 16 groups, with 10 members per group, enabling full-duplex real-time voice calls and seamless, hands-free communication without the need for manual PTT.
Automatic emergency alert: Equipped with a built-in gravity sensor, it automatically sends an SOS signal upon detecting a fall or prolonged inactivity; it also supports receiving “one‑key evacuation” commands.
Black box functionality: records personnel vital signs and on-site environmental data, facilitating post-event analysis.
Bone Conduction Communication Series (ZXF-Q10 Mask‑Style / ZXF-H6 Ear‑Hook Style / ZXF-H1 Headband Style):
Highly adaptable: Perfectly compatible with mainstream masks and helmets from MSA, Honeywell, Dräger, and other leading manufacturers, without compromising the original protective structure.
Clear noise cancellation: Leveraging bone conduction technology to filter out breathing sounds, it delivers crystal-clear calls even in noisy environments; the M8 shoulder mic supports digital voice control, freeing your hands.
2. On-site Relay Layer: Mobile Broadband Transmission Network
Communication‑type life‑saving illumination line + communication gateway/repeater gateway:
Multi‑mode integration: Combines private networks, public networks, and WiFi into a single system, supporting multi‑hop cascaded relay forwarding.
Scene Breakthrough: In subways, tunnels, and high-rise buildings, the firefighter’s distress beacon, smart air‑supplied respirator, and walkie‑talkie signals are relayed in real time to open outdoor areas.
Flexible Deployment: Combines wired (lighting‑line) and wireless (MESH) technologies, eliminating geographic constraints and enabling rapid coverage of signal‑dead zones.
EL/LED/Fiber Optic Lifesaving Lighting Cable:
Light‑guide integration: Not only does it provide directional lighting (with four modes—steady on, fast flash, slow flash, and guidance)—the fiber‑optic version also achieves “light conduction without electrical conduction,” ensuring safe signal transmission in flammable and explosive environments.
3. Back-end Command Level: Visualized Integrated Dispatch Platform
Integrated positioning tablet terminal + back-end control terminal:
Panoramic Situational Awareness on a Single Screen: Powered by Android tablets or PCs, it displays in real time the air‑breathing cylinder pressure, remaining air time, heart rate, altitude, activity status, and three‑dimensional position of all personnel online.
Intelligent Search and Rescue: Automatically displays pop-up alerts, prioritizes trapped individuals based on altitude and distance differences, and guides rescue teams to quickly pinpoint their locations.
Flat‑hierarchy command: Supports issuing evacuation orders to all personnel, to specific groups, or to individual members; the indoor‑attack registration system automatically scans entrants’ identities and equipment status, denying access to those who fail to meet the requirements.
III. Key Product Highlights and Technical Advantages
MESH self-organizing network + public network dual-channel hot standby: The RHJ680T emergency call device and the TC30 communication system support ZMESH ad-hoc networking and automatic switching between 4G/5G public networks. In areas without public network coverage, the devices automatically establish a mesh topology; if any node fails, the network self‑heals and reconfigures within milliseconds, ensuring uninterrupted connectivity.
Full-duplex natural voice calls + digital voice control: Unlike the traditional push-to-talk mode of conventional walkie-talkies, the ZXF‑TC30 system enables full‑duplex communication akin to a telephone. Paired with the M8/M5 shoulder‑mounted microphones’ digital voice‑activation technology—which recognizes only human speech—it frees your hands completely, enhancing both communication efficiency and safety.
Multidimensional Perception and Precise Localization: The individual‑soldier terminal not only transmits voice but also integrates BeiDou/GPS outdoor positioning and barometric pressure‑based indoor altitude measurement, with an accuracy of within 10 meters. Combined with intelligent voice‑broadcast data, the command center can obtain a real‑time “life profile” for each team member—covering stress levels, heart rate, body temperature, and location.
Optical Communication and Wired Relay Innovation: The communication‑enabled life‑saving illumination cable innovatively integrates a communication module into the cable itself, leveraging the stability of wired transmission to overcome wireless signal attenuation. It is particularly well suited for extending signals in long‑distance tunnels, subways, and high‑rise vertical shafts.
High-Level Security Protection: All communication devices feature IP67/IP68 protection ratings and are explosion-proof certified (Ex), enabling stable operation in environments ranging from –30°C to 70°C, as well as in conditions characterized by high salt spray, strong electromagnetic interference, and the presence of flammable or explosive substances.
IV. Typical Application Scenarios
- High-rise building rescue: The RHJ680T personal locator beacon’s altitude‑based positioning feature is used to identify the floor, while a communication gateway extends indoor signals outdoors, overcoming the shielding challenges posed by reinforced concrete.
- Subway/Tunnel Accidents: A communication‑grade emergency lighting cable is installed as the backbone network, integrated with the TC30 communication system to provide long‑distance, dead‑zone‑free coverage, ensuring seamless communication between trapped personnel and ground command.
- Mine/Underground Rescue: In flammable and explosive gas environments, fiber-optic life‑saving lighting cables and explosion‑proof bone‑conduction headsets are used to ensure communication and illumination under intrinsically safe conditions.
- Large petrochemical plant: Leveraging the M8 shoulder‑mounted microphone’s noise‑reduction capabilities, clear instructions are delivered in high‑noise areas such as compressor and pump rooms; an intelligent air‑breathing system is integrated with gas detectors to proactively assess environmental risks.
- Internal‑Attack Operations Registration: Utilizes an internal‑attack registration device to swiftly scan entrants and synchronize data in real time with the integrated positioning system, ensuring that personnel can “enter, be seen, be reached, and exit.”
