| Summary: | In view of problem that performance of mine-used wind speed sensor is easy to fall because of poor working conditions, a kind of mine-used wind speed sensor based on DDS technology was designed. The sensor adopts DDS technology to design ultrasonic oscillation circuit with high stability resonance frequency, and uses Karman vortex street principle to achieve real-time, accurate measuring of wind speed value. The experiment result shows reliability of the sensor is high, measurement error is smaller, and anti-interference is strong. |
