Abstract: In order to accurate measurement mine water inrush flow under various harsh environment, a polarity correlation algorithm of velocity measurement system is proposed based on DSP. The basic principle of flow velocity measurement is proposed and hardware circuit is designed based on polarity correlation algorithm. On-the-spot experiment is carried out to compare the data dotained by means of two different measure principles. The results show that the polarity correlation velocity measurement system based on DSP can accurately measure water inrush flow with very high precision.

Key words: flow velocity measurement, polarity correlation algorithm, DSP
