STM32F103ZET6的多普勒流速计设计
|
摘要
随着科技的进步,Doppler原理在现代测量技术中被广泛应用。为解决传统接触式流速计操作不便、测量精度低的问题,设计了一种非接触式流速计。根据Doppler原理,利用流速传感器发射电磁信号,通过分析测量水流所产生的Doppler频移最终获取水面流速。测试结果表明,该流速计操作简便,精度高。
With the advancement of modern science and technology,the principle of Doppler has been widely used in modern technology of measurement.In order to solve the problems of inconvenient operation and low accuracy of the traditional contact flow meter,a non-contact flow meter is designed.In accordance with the Doppler principle,the flow signal is used to transmit the electromagnetic,the flow rate of the water surface is finally obtained by analyzing the Doppler frequency shift generated by measuring the water flow.The test results show that the flow meter is easy to operate and has high precision.
