High-performance edge systems, rugged tablet PCs, panel displays, and interactive interfaces optimized for heavy operations.
Exploring the evolution of computational hardware within modern digitalized mining environments.
Modern extraction environments demand computing devices with strict compliance certificates such as ATEX Zone 1/2 and IECEx. The atmospheric hazard posed by combustible coal dust and volatile methane gas requires circuits to be built without creating spark-prone ignition paths, reducing thermal risks during massive continuous operations.
On-board heavy vehicle computers (such as excavators, dumpers, and drillers) suffer constant low-frequency and high-frequency structural vibration. Mining-grade tablets and vehicle panel computers incorporate solid-state storage (M.2 NVMe SSDs), reinforced vibration-dampening mounting systems, and high-impact structural casings.
Underground shafts are loaded with fine abrasive rock particles, moisture, and acid wash. Fully sealed IP65, IP66, and IP67 computing enclosures shield delicate internal components from high-velocity water jets and micro-particulate dust ingress, ensuring zero downtime in continuous operations.
Across the mining supply chain, from copper extraction in the high-altitude Andes to deep-shaft coal operations in Australia, the demand for enterprise computing hardware has shifted from generalized industrial PCs to specialized, ruggedized computational nodes. These machines provide real-time telemetry, monitor atmospheric composition, manage autonomous heavy machinery routes, and handle high-speed telemetry translation at the edge.
From basic SCADA terminals to highly integrated artificial intelligence nodes capable of decentralized predictive modeling.
With processing chips like the Rockchip RK3588 integrating multi-core NPUs, mining computers can now process video feeds locally inside the cabin. Cameras can monitor driver fatigue, detect debris blockages on mechanical conveyances, and scan tunnel faces for signs of geological shifting, alerting crews within milliseconds without relying on high-latency cloud connections.
Modern extraction operations span enormous geographical spaces. Edge computing gateways combining Ubuntu OS with LoRa, 4G LTE, and Wi-Fi 6 act as translation nodes. They aggregate sensor data (such as acoustic noise levels, decibel meters, seismic sensors, and chemical sniffers) and transmit warning packages across the network.
Operating computational nodes in remote areas requires high energy efficiency. Hardware platforms designed with ARM architectures consume less than 15 watts of power while delivering high performance. This low thermal footprint allows fanless cooling designs, ensuring that dust isn't drawn inside the housing, extending product lifecycles and lowering Total Cost of Ownership (TCO).
Smart command rooms utilize massive multi-point interactive display panels (up to 86 inches with 20-point touch systems) to map out underground operations. Real-time mapping, video conferences with field engineers, and asset control dashboards allow control room operators to collaborate effectively during critical production periods.

How specialized computing devices solve environmental challenges in specific zones.
Deep tunnels are saturated with high humidity, dust, and corrosive water. Technicians and operators use rugged, drop-resistant tablets (IP65 to IP67) with integrated GPS and 4G LTE to view real-time mine maps, report geological faults immediately, and check automated pump telemetry on the spot.
Excavator operators and haulage drivers rely on vehicle panel computers mounted in their cabins. Connected via CAN bus, these terminals provide immediate engine diagnostics, route tracking, and load stats. High-contrast screens maintain legibility under bright sunlight during open-pit operations.
Placed at strategic ventilation points, edge gateway computers collect data from gas and noise sensors. If decibel or methane levels spike beyond safety thresholds, these gateways process the warning signals locally and trigger automated alarms to safeguard the underground workforce.
Integrating components into complete solutions to improve efficiency, productivity, and safety.
Our solutions connect in-vehicle tablet PCs with centralized servers via private networks. Dispatchers can dynamically route autonomous dumpers based on loader queue times, payload levels, and road conditions, reducing idle times and fuel consumption across operations.
By connecting analog modbus noise sensors and digital gas detectors to a central edge gateway, sites can implement real-time safety monitoring. Systems translate raw Modbus/RTU inputs into MQTT payloads, providing real-time data to safety dashboards in the main control room.
Fray Tech's fanless industrial panel PCs are deployed as HMI systems for slurry pumps, conveyors, and sorting machinery. These high-resolution touch displays allow operators to adjust processing parameters directly on the factory floor, withstanding shocks, dust, and washdowns.
Our interactive 4K smart boards serve as the hub for operational command rooms. Mining planners, geologists, and engineers can overlay real-time 3D topographical data with field reports and live telemetry, making fast, data-driven decisions during recovery and production phases.
Fray Tech’s vision for the next generation of industrial computing devices.
We are expanding our use of high-performance ARM platforms, including the Rockchip RK3588, to deliver advanced edge AI capabilities with low power draw. This enables high-speed, local computer vision and machine learning models directly on remote field devices.
Our engineering team is designing new ultra-thin, explosion-proof HMI housings that meet strict Zone 1 explosion protection requirements. This allows for safe, direct interaction with machinery in highly hazardous gas environments.
We are integrating LoRaWAN, 5G, and satellite backup connectivity directly into our edge gateways, ensuring continuous, reliable data transmission even in deep shafts or isolated, remote areas.
Expert answers regarding technical details, certifications, and customization options for industrial mining hardware.
Underground operations pose constant gas (methane) and coal dust explosion hazards. ATEX Zone 1 and Zone 2 certifications ensure the device is intrinsically safe or enclosed in a manner that prevents internal electrical sparks or thermal buildup from igniting surrounding flammable mixtures.
The RK3588 features a built-in NPU capable of up to 6 TOPS of processing power. This allows systems to run deep learning algorithms locally (e.g., driver monitoring or geological hazard scans) without needing an active internet connection, reducing data transmission costs and latency.
Fanless designs rely on passive conduction through aluminum heatsink fins. With no internal fan drawing in outside air, fine mining dust is prevented from coating internal components and causing overheating or static failures, which greatly improves reliability.
Yes. We provide comprehensive ODM/OEM customization, including custom branding, specialized mounting systems, changes to internal I/O ports (such as isolated serial ports or CAN Bus), wide-voltage power supplies, and customized OS environments.
