Abstract

Pump plays a key role because it is an important device used to drain water in mine. It is very significant to keep it working normally. The flow velocity and the flux of the pump are the typical indexes that can indict its state. A measurement system that can measure these two indexes is designed to detect the state of the pump. The virtual instrument technology based on LabVIEW is used to build the software part of this measurement system. The ultrasonic sensor is also used in this system. Because of the use of this sensor, the pump can be detected without stopping working. The mathematical model of the correlation function for processing the discrete signal is built. The signal from the DAQ card is processed based on the model above. The value of the flow velocity and the flux is obtained. The precision and efficiency of the measurement are enhanced.
