Abstract: The paper proposed a design scheme of ventilation volume monitor of ventilation tube, and introduced installation place, measuring principle and designs of hardware and software of the monitor. The monitor uses ultrasonic time-difference method to measure wind velocity and ventilation volume at exit of ventilation tube. It can manually set the minimum wind velocity and volume, and send out alarm signal to remind relevant personnel to maintain ventilation equipment when the measured value is less than the setting value.
