Abstract

An arrangement for data transmission in a mine, and a cable reel. Data transmission between an information system of the mine and an information system of a mining vehicle is arranged using two data transmission cables. The data transmission cables are arranged in a supply cable that can be stored on a reel in the mining vehicle. The reel has a rotatable drum on which the supply cable can be wound. A first end of the drum has a first rotating connection element for connecting the first data transmission cable to the information system of the mining vehicle. A second end of the drum has a second rotating connection element for connecting the second data transmission cable to the information system of the mining vehicle.

Claims

1. An arrangement for data transmission in a mine or the like, the arrangement comprising:

a mine information system consisting of at least a control unit of the mine,

a mining vehicle information system consisting of at least a control unit of the mining vehicle,

at least one supply cable that comprises at least one data transmission cable and is arranged to transmit data between the information system of the mine and the information system of the mining vehicle, and the first end of the supply cable is connected to the information system of the mine,

a reel arranged in the mining vehicle and having a drum rotatable around its centre axis for storing the supply cable in the mining vehicle,

means for connecting the second end of the supply cable to the reel drum,

connecting means for connecting the data transmission cable in the supply cable from the rotating drum to the information system of the mining vehicle, and wherein

the supply cable has at least a first data transmission cable for transmitting data unidirectionally from the information system of the mine to the information system of the mining vehicle, and a second data transmission cable for unidirectional data transmission from the information system of the mining vehicle to the information system of the mine,

said connection means comprise a first rotating connection element on the first end of the drum, and a second rotating connection element on the second end of the drum,

the rotating connection elements are arranged on the centre axis of the drum,

the rotating connection element comprises a rotor and a stator, with the rotor arranged to rotate with the drum around the centre axis and the stator arranged non-rotatable,

the rotor of the first rotating connection element is connected to the first data transmission cable of the supply cable, and the stator is connected to the information system of the mining vehicle,

and the rotor of the second rotating connection element is connected to the second data transmission cable of the supply cable, and the stator is connected to the information system of the mining vehicle.

2. An arrangement as claimed in claim 1, wherein

the supply cable comprises more than two one-way data transmission cables,

and only two data transmission cables at a time are connected to transmit information between the information systems.

3. An arrangement as claimed in claim 1, wherein

the supply cable comprises at least one electric supply cable,

and the drum has power transmission means for establishing an electric connection between the electric supply cable and mining vehicle electric system.

4. An arrangement as claimed in claim 1, wherein

the data transmission cables are optical fibre cables,

and the rotating connection elements are rotating optical fibre connectors.

5. A cable reel for storing a supply cable of a mining vehicle, the reel comprising:

a drum on the outer surface of which a supply cable is wound,

a first end and a second end of the drum,

a centre axis around which the drum turns; and

,

connection means for connecting the at least one data transmission cable in the supply cable to an information system external to the reel, and wherein

the supply cable has a first data transmission cable and a second data transmission cable,

on the first end of the drum, there is a first rotating connection element,

on the second end of the drum, there is a second rotating connection element,

the rotating connection elements are arranged on the centre axis of the drum,

the rotating connection element comprises a rotor and a stator, and the rotor is arranged to rotate with the drum around the centre axis and the stator is arranged non-rotatable,

the rotor of the first rotating connection element is connected to the first data transmission cable of the supply cable, and the stator is connected to the information system of the mining vehicle,

and the rotor of the second rotating connection element is connected to the second data transmission cable of the supply cable, and the stator is connected to the information system of the mining vehicle.

6. A reel as claimed in claim 5, wherein

the supply cable comprises at least one electric supply cable,

and the drum has power transmission means for establishing an electric connection between the electric supply cable and the electric system of the mining vehicle.

7. A reel as claimed in claim 5, wherein

the data transmission cables are optical fibre cables;

and the rotating connection elements are rotating optical fibre connectors.
