Benefits of technology

[0008] An advantage of the invention is that bidirectional data transmission between the information system of the mining vehicle and the information system of the mine can be implemented using two unidirectional data transmission cables that can be arranged inside the supply cable. Because information is transmitted in the data transmission cable in one direction only, it is possible to transmit very large amounts of data without problems. Further, when a reel equipped with the rotating connection elements of the invention is used, the unidirectional data transmission cables can be connected in a relatively simple manner to the information system of the mining vehicle.

Problems solved by technology

However, the limited data transmission capacity of the data transmission cable then creates a problem.
In addition, bidirectional data transmission in one cable requires complex devices to arrange.

Embodiment Construction

[0019]FIG. 1 shows an arrangement of the invention. The mining vehicle 1 can be a loading vehicle like the one shown in FIG. 1, or it may be a rock drilling rig, transport vehicle or the like. The mining vehicle 1 can be electrically driven, in which case it is connected by a supply cable 2 to the electrical power network 3 of the mine. One end of the supply cable 2 can be connected to a connection unit 4 arranged in the mine, and the other end of the cable can be connected to a reel 5 in the mining vehicle 1. The reel 5 is arranged rotatable relative to its axis 6 so that a required amount of supply cable 2 can be wound around the reel 5. The reel 5 can have power transmission means, such as slip rings or the like, by means of which electric conductors in the supply cable 2 can be connected to the electric system 7 of the mining vehicle 1 that conducts electric current on to a motor 8 and other electric devices in the mining vehicle 1. Means for affecting the rotation of the reel 5...

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.

Description

BACKGROUND OF THE INVENTION [0001] The invention relates to an arrangement for data transmission in a mine or the like, the arrangement comprising: an 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; and connecting means for connecting the data transmission cable in the supply cable from the rotating drum to the information system of the mining vehicle. [0002] Th...
