ROCK CONVERGENCE AND EXPANSION METER IN MINES

摘要

The solution concerns the gauge of convergences and expansion of rock materials in mines with the use of an optical cable for the transfer and with the output of the monitored data into the computer. The reading devices are individually connected to the conversion unit of the convergence gauge, whose outputs are connected to the corresponding nodes of the node unit by the optical cable, where the block of the node reception is on the input of the node unit and the block of the node multiplex is on the output of the node unit, while the output of the node unit is interconnected with the centre block, which is connected with the computer.<IMAGE>
