Abstract
A wind speed sensor for coal mine is studied based on the thermal film working principle.Except the function of detecting wind speed
the sensor also has the functions of detecting the temperature of wind and recognizing the wind direction.To improve the reliability of the sensor
the redundancy design theory is adopted to design the chip structure
where the cold storing system for sensing films of wind speed is added.The wind speed sensor is operated under constant operating temperature.Its measurement range is 0.1
1
5m/s and the sensor has characteristics of reliable structure
good dynamic character and high measurement resolution.
