A world first wireless condition monitoring sensor system has been developed by VIPAC Engineers and Scientists for variable speed machinery.
Jointly funded by the Australian Coal Association Research Program (ACARP) and VIPAC, the system consists of four parts including a smart sensor, transceiver, PC and a communication module.
The smart sensor automatically detects a machine’s condition using alarm ‘mask’ methodology.
The machine data is remotely transferred regularly to a transceiver without the need for cabling.
Machine fault severity software is used to save, analyse and review data on a PC.
According to the condition monitoring sensor system’s project manager and VIPAC representative Mingfei Luo, the system was trialled by an Xstrata mine in the Hunter Valley.
“Through the trials, we were able to demonstrate that the system works on any mobile machine, whether it operates at a constant or variable speed,” Luo told MINING DAILY.
“The system has the ability to determine when machine maintenance is needed, what parts need replacing and where the part is located in the system.”
“On a minesite there are numerous mobile machines that operate 24 hours a day, seven days a week.
“In the past, there has not been a product that can actively and accurately monitor the condition of each machine because a wireless network has not been readily available. Using cables would be pointless and impossible, so the only other alternative has been, up until now, employee condition monitoring.”
