Safewall Barricades replaces conservative time-based wait periods with embedded IoT sensors and proven maturity analytics based on the ASTM C1074 standard. The system continuously monitors the temperature-time profile of curing shotcrete barricade walls to calculate compressive strength in real time, giving engineering teams the data to approve paste plug pours with confidence.
How It Works
System Components
| Component | Function | Key Specs |
|---|---|---|
| Sensor Matrix | Temperature measurement across full barricade wall | Three-line design, precision thermistors, ruggedised cable, spray-tolerant |
| Connectivity & Power Box | RF transmission of sensor data to gateway | Battery powered, ruggedised enclosure, positioned outside fill zone |
| Edge Gateway | Receives RF data, buffers, transmits to cloud | Industrial-grade enclosure, Wi-Fi backhaul, battery backup |
| Cloud Platform | Maturity calculation, strength estimation, alerting | ASTM C1074 engine, real-time dashboards, configurable thresholds, audit trail |

Data Flow
Network Architecture
Sensor lines communicate with the connectivity and power box via direct wired connection. The power box transmits data wirelessly over RF to the edge gateway, requiring no existing network infrastructure at the barricade location. The gateway connects to the mine’s Wi-Fi network and transmits data to the surface. All cloud communications use TLS 1.3 encryption. The gateway buffers data locally during connectivity interruptions and synchronises automatically when the link is restored, ensuring no data loss in intermittent network conditions.
