Zhengze Fire Rescue Positioning System: Empowering Fire Rescue & Upgrading Intelligent Fire Site Command
2026-09-03
At fire and disaster emergency rescue sites, the core factors restricting rescue efficiency and endangering firefighters’ safety are often not the disasters themselves, but the "information black holes" caused by on‑site information barriers. In traditional rescue modes, critical data including the precise location of interior‑attack firefighters, remaining SCBA service time, firefighter vital sign monitoring readings, and ambient temperature can only be shared intermittently over walkie‑talkies. This gap makes reliable fire site command difficult, as commanders cannot obtain real‑time, comprehensive situational awareness.
To address these real‑world operational pain points, Nanjing Zhengze Technology Co., Ltd. has developed its fire rescue positioning system. This intelligent fire rescue solution integrates data collection, intelligent transmission, command scheduling and emergency search‑and‑rescue capabilities. The Zhengze fire rescue positioning system combines indoor‑outdoor firefighter positioning, emergency distress call support, interior‑attack personnel registration, SCBA pressure monitoring, firefighter vital sign monitoring and real‑time personnel status tracking. Built around self‑developed MESH ad‑hoc network fire rescue technology and 4G/5G dual‑channel transmission, the platform resolves unstable data transmission and signal dropout within complex built‑up environments. Boasting simple operation, rich functions and robust field performance, the system protects frontline responders and shifts fire‑ground operations from the old model of “person searching for information” to modern‑day “information finding personnel”.
Top‑Level Architecture: Six Core Modules Build a Closed‑Loop Intelligent Rescue Ecosystem
The Zhengze fire rescue positioning system is not a standalone piece of hardware. It is a complete, logically closed intelligent rescue platform built for large‑scale emergencies inside complex urban buildings. Six coordinated core modules create a full‑chain “perception‑transmission‑decision” workflow and transform traditional fire site command workflows.
Individual Comprehensive Positioning Terminal: Frontline Firefighter Portable Information Node
Acting as the wearable data hub for every interior‑attack firefighter, this individual terminal powers on automatically. It delivers directional guidance via numerical outputs alongside real‑time voice data feedback. Height‑difference measurement identifies different floors rapidly, solving positioning challenges inside high‑rise buildings. For outdoor operations, Beidou and GPS dual‑satellite receivers deliver accurate latitude‑longitude coordinates. The on‑screen display shows live heart rate and SCBA pressure data, so each firefighter can continuously track their own operational status.
Vital Sign Monitoring Device: Real‑Time Physiological Data Capture
This hardware unit collects real‑time physiological measurements for deployed rescuers and displays firefighter vital sign monitoring data locally. When two or more team members operate together, the device shows real‑time distance between personnel to support coordinated team movements. All biometric data transfers over Bluetooth to the individual positioning terminal and synchronizes back to the central fire rescue positioning system for site‑wide visibility of crew health conditions.
Comprehensive Positioning Beacon: On‑Site Navigation Marker & Signal Relay Base Station
Positioning beacons perform dual roles: on‑site navigation markers and signal relay hardware. Users mark critical locations such as fire zones, safety exits and water sources. Once deployed, beacons broadcast navigation signals to guide crews to target zones. Beidou and GPS dual‑mode positioning delivers coordinate accuracy ≤10 meters; nearby firefighter positions render directly within the 3D situational model. The relay capability extends overall signal coverage. Combined with high‑volume voice announcements and multi‑color high‑brightness directional lamps (color‑coded for different site markers), these beacons improve situational orientation for crews operating in disorienting emergency environments.
Interior Attack Personnel Registration Device: Digital Safety Checkpoint
Serving as a “digital sentinel” for safety officers managing entry and exit at fire‑ground boundaries, this unit registers interior‑attack firefighters’ identities, entry‑exit timestamps, SCBA pressure and heart‑rate readings. Built‑in logic denies access for personnel with insufficient SCBA pressure or abnormal vital signs, mitigating risks at the source. Safety officers can broadcast evacuation orders to individuals, groups or all interior‑attack teams. Registration records feed in real‑time to the fire rescue positioning system for full traceability of personnel movements.
Comprehensive Positioning Tablet Terminal: Commander’s Unified Situational Dashboard
The tablet terminal serves as commanders’ “one‑map situational view” for intelligent fire site command. It supports fast on‑site 3D situational modeling with multi‑touch zoom, pan and rotate controls. Commanders visualize real‑time locations of all interior‑attack personnel on the building 3D model. The dashboard aggregates SCBA pressure monitoring outputs, firefighter vital sign monitoring alerts, equipment fault notifications, entry‑exit logs and ambient temperature readings. When firefighters trigger emergency alarms, pop‑up notifications appear automatically. The system calculates search‑and‑rescue priority according to height offset and horizontal distance, enabling targeted evacuation commands for single users or all interior‑attack personnel.
Dual‑Network Communication Backbone: Reliable Full‑Scenario Data Transmission
MESH ad‑hoc network fire rescue technology works alongside 4G/5G public cellular networks in an auto‑switching dual‑channel architecture, maintaining connectivity even when public infrastructure fails. This communication stack originates from the “dynamic ad‑hoc network and relay transmission technology integration” concept proposed by Wang Xinwen, Chairman of Zhengze Technology. It addresses signal shielding and connectivity blackouts inside large buildings and disaster‑damaged zones, delivering stable underlying support for the whole fire rescue positioning system.
In‑Depth Technical Breakdown: Three Core Technologies Solve Key Rescue‑Site Challenges
China’s Ministry of Emergency Management Fire and Rescue Bureau published the Construction Plan for Key Emergency Communication Equipment for Joint Operations at Complex Urban Building and Severe Natural Disaster Sites. It identifies three core pain points: difficult interior‑attack positioning, patchy communication coverage, and disorganized command workflows. The Zhengze fire rescue positioning system’s technical design directly addresses these industry‑wide requirements.
Indoor‑Outdoor Integrated Positioning Technology: Eliminate Positioning Blind Zones
GPS and Beidou satellite signals are heavily attenuated by reinforced concrete in high‑rises and underground spaces, rendering conventional location tools ineffective. This platform merges outdoor satellite positioning, barometric altimetry for floor recognition, and signal‑strength‑based relative‑positioning algorithms to achieve seamless indoor‑outdoor firefighter positioning. Positioning beacons achieve 1‑meter ranging accuracy with effective working range exceeding 500 meters, resolving confusion over crew locations and floor levels inside complex structures.
Decentralized MESH Ad‑Hoc Network: Maintain Uninterrupted Emergency Communications
Sudden communication failure ranks among the gravest risks during disaster response. The proprietary decentralized MESH ad‑hoc network fire rescue architecture treats every connected device as a receiving‑and‑forwarding network node within a mesh topology. If one node is damaged or drops offline, the network recalculates transmission paths within milliseconds. Single‑hop alarm transmission reaches ≥2500 meters, with support for up to 10‑hop relay chains. This covers super‑tall buildings, large underground facilities and enclosed spaces to eliminate communication dead zones.
Multi‑Source Data Fusion & Intelligent Decision‑Making: Enable Data‑Driven Command
Beyond raw data collection, multi‑source data fusion algorithms process scattered datasets and convert them into actionable command inputs. The intelligent search‑and‑rescue function ranks rescue priorities automatically by analyzing alarm‑source height offset and horizontal distance, replacing old subjective experience‑based assessment workflows. Fast 3D modeling together with real‑time position plotting transforms abstract datasets into visual spatial situational maps, empowering commanders to make fast, informed operational decisions.
Real‑World Deployment Scenarios: Disaster Response & Routine Fire Service Training
The Zhengze fire rescue positioning system is already deployed by fire‑rescue units across China. Rather than functioning as isolated emergency hardware, it interconnects individual firefighter alarms, team‑level coordination and command‑center oversight to build a three‑tier intelligent safety network covering individuals, teams and command staff.
High‑Rise Building Firefighting: Indoor‑outdoor firefighter positioning with height‑difference detection solves the familiar challenge of “hearing calls but not locating crew”. Commanders review personnel distribution on the 3D situational map and send targeted evacuation orders to prevent group safety incidents.
Large Commercial Complexes & Underground Spaces: Deployable positioning beacons create temporary relay networks to extend signal coverage, overcoming attenuation and communication black holes within enclosed built‑environments. Data and emergency orders flow reliably between frontline crews and command.
Chemical‑Hazard Incident Response: Continuous SCBA pressure monitoring and firefighter vital sign monitoring maintain safety oversight for teams working inside high‑risk chemical‑hazard zones, supporting rational work‑cycle management for exposed personnel.
Earthquake & Structural‑Collapse Search‑and‑Rescue: Positioning beacons deliver ≤10‑meter coordinate accuracy to build ad‑hoc navigation networks amid rubble, helping locate both trapped civilians and active rescuers to boost disaster‑response efficiency.
Routine Fire‑Service Drills: The fire rescue positioning system also supports day‑to‑day training. It captures full‑session operational data, records crew status and facilitates post‑exercise command‑workflow reviews, supplying objective data to improve training quality and overall operational readiness.
