Abstract
A wirelessly-linked RFID tracking system is disclosed herein. The system includes low-power wirelessly-linked RFID readers in communication with a mine radio network to detect and transmit information received from a plurality of RFID tags. The RFID readers transmit tag information to a local server for providing notification and/or alarm information to system users as required under the Miner Act of 2006. The RFID readers may further include environmental sensors to sense and communicate environmental conditions wirelessly. In addition, the optional capability of hi-intensity warning LEDs mounted on the reader devices, may be deployed to alert personnel of an emergency condition even when hundreds of feet away from the device, irrespective of background noise prevalent in mining operations. The disclosed system communicatively links a plurality of wireless RFID readers to each other and/or to the mine radio network to create a data path from an underground environment to a surface environment. It should be appreciated that the system may be applied in a number of environments, including, but not limited to mines, oil platforms, industrial surface complexes, such as petroleum refin…
