摘　　要：提出了一种风筒风量监测仪设计方案,介绍了监测仪的安装地点、测量原理及其软硬件设计。该监测仪采用超声波时差法测量风筒出口处风速及风量,可人工设定最小风速、风量值,当实测值小于设定值时,发出报警信号,提示相关人员检修通风设备。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.
