Important results from the project
We have identified some sensors that meet the requirements we set up to detect gas concentrations that may indicate that plastic is heating up and oil spraying out of hydraulic hoses. We need a system with hoses that suck air from critical positions and for the gas to the measuring sensor to get sufficient sensitivity. It is possible to transfer the collected measurement data to Epiroc´s Certics system and ABB´s 800xA on-line. Diagnostics: Identified oil leaks on a mine dump truck. The AR system has been commercialized by ABB. Epiroc has also included the feature in its product program.
Expected long term effects
We have already commercialized AR systems within ABB and diagnostic systems within Epiroc. Boliden has also bought a number of AR systems and seen that the function with measuring sensors connected to drones is very interesting for replacing manual measurement after blasting. It is also possible to reduce the lead time before you can start breaking. We have been able to identify the possibility of making diagnostics on crushers, mills, etc. "on-line", which avoids downtime of days and corresponding production losses (SEK million).
Approach and implementation
Tested 20 different measuring instruments in parallel at RISE. Epiroc´s cables were mounted and power was turned on. Measured from normal operation to too high current. Chose three sensors to move on with. Measured on mining vehicles with tubes to important parts. Tested that it was possible to send measurement data on-line. Examined diagnostics with drones that had measuring sensors mounted. Could detect explosive gases and oil leaks. Measuring sensors were mounted on-line on Epiroc´s vehicles in a mine and logged data continuously for a few weeks.
