【Abstract】 Based on LabVIEW and ADXL357 three-axis acceleration sensor, this system designs a system that can detect and diagnose the state of the main fan of coal mine. In order to timely and accurately monitor the operation status of the mine main fan, the software system uses LabVIEW as the development platform, which has the functions of multi-dimensional acquisition program, display and analysis program, etc. The network realizes its intelligent diagnosis. When the vibration of the fan exceeds the limit, it analyzes the fault signal and gives the diagnosis result. The system design can meet the requirements and has practical value for the safety production of coal mines.更多还原
