Array Microseismic Life Detector

Core Capabilities

Wireless Microseismic Search Under Rubble

The CRMB-RAD is a multi-sensor wireless acoustic and seismic life detection array engineered for urban search and rescue (USAR). It captures micro-vibrations and active tapping signals propagating through collapsed concrete, steel beams, and structural debris, accelerating victim localization while digitally filtering environmental noise.

CAPABILITY 01

Compare Vibration Across the Sensor Array

Multiple wireless sensors continuously capture and compare active vibration and micro-seismic tapping signals across a search zone. Live signal bar graphs on the central terminal allow operators to identify the sensor closest to the victim instantly.

Supports 2 to 10 wireless sensors connected simultaneously to one central terminal
Up to 8 m detection radius per sensor under suitable structural media conditions
Multi-channel comparative analysis narrows the survivor location efficiently

CAPABILITY 02

Filter Noise and Narrow the Search Zone

Disaster sites present extreme acoustic interference from wind, settling debris, and emergency plant. The CRMB-RAD terminal provides precise high- and low-frequency filtering across 0.1–5000 Hz to isolate subtle human tapping, scratching, and vocal vibrations from ambient background noise.

Broad 0.1–5000 Hz sensor frequency response range
Adjustable high-pass and low-pass digital filters eliminate machinery and traffic noise
Independent channel level calibration and sensitivity adjustments

CAPABILITY 05

Two-Way Intercom and Deep Confined Sound Probe

Once tapping signals confirm survivor presence, an intercom probe on a 10-metre cable can be lowered into voids to establish two-way voice communication, comforting survivors and gathering critical medical status before breaching.

Applications

Array Microseismic Life Detection for Rescue Operations

Engineered for municipal fire rescue detachments, national USAR task forces, military engineering corps, and industrial mine rescue teams worldwide.

Rescue team deployed at an earthquake rubble disaster site with seismic detector

Earthquake Disaster Rescue

Rapid grid deployment across wide earthquake rubble fields. Sensors detect faint rhythmic tapping and vocal vibrations through collapsed concrete slabs and brick masonry when optical tools cannot penetrate.

Rescuer placing sensor probe inside confined collapse void

Structural Collapse & Confined Spaces

Magnetic attachment to steel columns, shoring props, and reinforced concrete surfaces. Allows safety officers and search teams to monitor structural movement while searching tight subterranean voids.

Field deployment and search exercise on rock and rubble slope

Landslides, Mines & Tunnels

Insertion spikes drive into loose debris, tailings, and geological fissures during landslides or tunnel collapses, comparing acoustic wave arrival times to calculate survivor distance and bearing.

Operational Scenario

Triangulating Survivor Signals: An Illustrative Search Deployment

The scenario below illustrates how a search team deploys the CRMB-RAD array on collapsed structural media. It is illustrative and actual results vary with structural medium, ambient acoustic interference, probe coupling, and survivor tapping force.

Deploy, Compare and Communicate: Step-by-Step Procedure

Situation

A multi-storey commercial building suffers pancake collapse following a seismic event. Rescuers establish a silence period on site, but ambient street noise and ongoing shoring operations generate complex background acoustic interference.

Potential use

The search detachment deploys six hexagonal sensors in a 15-metre perimeter around the suspected collapse void. The operator activates low-pass filtering on the 8-inch terminal to suppress heavy machinery rumble, calls for three rhythmic taps from trapped occupants, and watches real-time bar graphs jump on channels 02 and 03. Moving two auxiliary probes inward pinpoints the highest amplitude point to within 1.5 metres.

Decision support

With the search sector narrowed, the team feeds the 10-metre intercom probe through an adjacent bore hole. Two-way voice confirmation confirms two conscious survivors before heavy hydraulic breaching equipment is committed, avoiding accidental collapse of the surviving void.

Frequently Asked Questions

Procurement & Deployment

Answers to common operational and technical questions from USAR commanders and emergency procurement teams. Confirm project-specific requirements with the technical team.

Can the system detect an unconscious survivor?

The CRMB-RAD requires an active acoustic tapping, scratching, or vocal vibration signal to calculate bearing and location. For unconscious, motionless survivors who cannot produce active signals, deployment alongside ultra-wideband radar life detectors (such as the LSJ-M or HXDMR-300) or thermal cameras is recommended to detect breathing and body heat.

How does the system filter out rescue site machinery noise?

The system incorporates digital signal processors with customizable bandpass filters across 0.1–5000 Hz. Operators can set low-pass and high-pass cutoffs to silence low-frequency rumble from excavators and generators or high-frequency wind noise, isolating the specific acoustic signature of human tapping.

How many sensors can be connected simultaneously?

The standard system configuration supports 2 to 10 wireless micro-seismic sensors connected concurrently to a single 8-inch control terminal. Teams can deploy fewer probes for rapid reconnaissance or the full 10-probe array for wide multi-point structural perimeter triangulation.

What mounting methods are available for different collapse media?

Each sensor node features dual mounting interfaces: an integrated high-flux magnetic base for instant attachment to steel structures, pipes, and shoring beams, plus interchangeable hardened steel ground spikes that push directly into loose soil, mud, and gravel debris.

What warranty and calibration support is available?

All CRMB-RAD systems come with a standard 12-month manufacturer warranty. Complete documentation including CE, ISO, and RoHS compliance certificates, factory calibration reports, operational manuals, and spare parts availability are provided with every order.
