Real-time location tracking software to keep personnel safe

Schauenburg Systems offers a cutting-edge real-time workforce locator (RTWL), a location tracking software designed to track and monitor personnel in surface and underground mining operations. The RTWL system provides real-time location tracking of mining personnel, enabling instant workforce location across the entire mine in emergencies such as gas leaks or fires. This ensures effective preparation for emergencies and the rapid deployment of rescue teams to eliminate manual search times for lost personnel.

Using radio-frequency (RF) technologies and wireless devices, the RTWL system collects actionable data that integrates into Schauenburg Systems’ SmartMine IoT platform. This data can be analysed to allocate resources and tasks, efficiently streamlining workflows for increased productivity.

Schauenburg Systems’ mining safety tracker software collects data at a 1 to 5-second interval, sending out status messages such as operational status, error state, initiated distress messages and low battery status to a command hub. It also offers a live map view of geo-fenced zones, such as danger areas, safe areas, and prohibited areas, and sends out alerts when tags enter or leave those areas.
