“In another world first, NLT Australia working with technology partner Wavetrend have designed and approved an Exia-approved reader in the messenger cap lamp that will connect onto our digital network,” NLT Australia managing director Tim Haight said.
NLT said a longwall mine could have tags deployed in as many locations as desired.
“Imagine every cut-through plus other key areas such as longwall roof supports,” the supplier said.
“Now as the miner wearing the Reverse Tracking Cap lamp moves through the mine, the lamp reads the deployed tags and transmits that information out on the NLT Digital Wi-Fi network.
“If the miner encounters a non-supported area, the tag reads are buffered and time-stamped in the lamp and transmitted once returned to a hot spot or fully covered section of the mine.”
Haight said the RTC lamp solution means there is no requirement to deploy and power the radio frequency readers.
“The system provides resolution similar to that of a GPS on the surface with ease of installation and greatly reduced cost over existing tracking systems,” he said.
NLT has IEC intrinsic safety approvals for a range of products, including:
- 802.11 a,b,g WAP
- Compact WAP
- Wi-Fi two-way messaging cap lamp
- LED Cap lamp
- RF readers
- RF tags
- Polaris all-in-one cap lamp
