Communication system in a mine, a node, and method
A communication system in a mine having a data network, a wireless network and a plurality of nodes. A communication node of a data network and a wireless network in a mine. A method for communicating in a mine.
1. A communication system in a mine comprising:
a remote station;
a data network in the mine on which solely data is sent throughout the mine to the remote station;
a wireless network in the mine on which voice and data is sent bidirectionally throughout the mine to the remote station separate and independent from the data network to the remote station; and
a plurality of nodes distributed and apart from each other that form the data network and the wireless network, each node having a data portion which receives and sends data on the data network, a wireless portion which receives and sends voice signals on the wireless network, and a power supply portion in electrical communication with the data portion and the wireless portion which powers the data portion and the wireless portion, at least a first node of the plurality of nodes receiving power from another node of the plurality of nodes, the first node in electrical connection with the another node, the remote station monitoring the nodes.
2. The system of claim 1 wherein data on the data network includes tracking information of an individual.
3. The system of claim 2 wherein the data on the data network is sent and received at least one node of the plurality of nodes and the data network is bidirectional.
4. The system of claim 3 wherein the data from the data network is sent on the data network and the wireless network.
5. The system of claim 4 wherein each node includes a data converter in communication with the data portion and the wireless portion which converts the data from the data network into a transmission signal that is transmitted on the wireless network.
6. A communication node of a data network and a wireless network in a mine comprising;
a housing;
a data portion disposed in the housing which receives data on the data network in the mine, the data network in the mine on which solely data is sent throughout the mine to a remote station which monitors nodes in the mine;
a wireless portion disposed in the housing which receives and sends voice signals on the wireless network in the mine, the wireless network in the mine on which voice and data is sent bidirectionally throughout the mine to the remote station separate and independent from the data network to the remote station;
a power supply portion disposed in the housing in electrical communication with the data portion and the wireless portion which powers the data portion and the wireless portion the power supply portion having a power port which receives power from another node; and
a data converter disposed in the housing in communication with the data portion and the wireless portion which converts the data from the data network into a transmission signal that is transmitted on the wireless network.
7. The node of claim 6 wherein the wireless portion includes a first radio disposed in the housing to transmit the transmission signal.
8. The node of claim 7 wherein the wireless portion includes a switch disposed in the housing in communication with the first radio and the data converter.
9. The node of claim 8 wherein the wireless portion includes an external fiber connector in communication with the switch to connect with an external fiber to transmit the transmission signal.
10. A method for communicating in a mine comprising the steps of:
receiving data wirelessly at a data portion of a first node of a plurality of nodes in the mine from a data network on which solely data is sent throughout the mine and to a remote station which monitors the nodes, the plurality of nodes distributed and apart from each other and form the data network and a wireless network separate and independent from the data network through which voice and data are sent throughout the mine to the remote station bidirectionally separate and independent from the data network to the remote station;
converting with a data converter in communication with the data portion the data from the data network into a transmission signal that is transmitted on the wireless network, the wireless network transmitting and receiving voice and data bidirectionally;
transmitting the transmission signal from the first node on the wireless network with a wireless portion of the first node; and
powering the data portion and the data portion with a power supply portion in electrical communication with the data portion and the wireless portion, at least a first node of the plurality of nodes receiving power from another node of the plurality of nodes, the first node in electrical connection with the another node.
