Strata Safety Products has received MSHA approval of its intrinsically safe wireless communications system, Strata CommTrac.
With no external antennas, battery back-up systems or hard-wire backbone needed to carry data from the mine, StrataCommTrac is a truly wireless communications and tracking system. It is the first completely wireless underground system to be approved.
Simple yet rugged fixed Communication nodes are standalone devices installed underground to form a digital mesh network.
These approved nodes are powered by four standard D-cell alkaline batteries which have a lifespan of approximately one year.
The newly MSHA-approved Miner Communicators are carried by miners and function as the system’s communicators and tracking devices. These devices interact with the fixed Communication Nodes, transmitting miner identification data for tracking and text messages for communication. All data is transmitted to the surface via a wireless gateway where it is monitored, tracked and logged. Strata
Commtrac is self-forming, self-healing and self-monitoring. System functions and battery levels are automatically monitored with system alerts sent to surface operators.
