Since ancient times, human beings have been curious about many phenomena in nature. Of course, the research and analysis of meteorology has a long history. It has developed into an era of advanced science, and meteorology has gradually matured. In today's meteorological research, methods can be divided into four types: observational research, theoretical research, numerical models: research, experimental research, in which observational research is the most widely used one, and it is usually adopted by general meteorological enthusiasts. Mode. In the meteorological observation topics of temperature, wind speed, wind direction, rainfall, humidity, etc., wind fan measurement is an indispensable part. The most widely known device for measuring wind speed is the anemometer. Existing anemometers are classified into rotary anemometers, hot wire anemometers, ultrasonic anemometers, laser Doppler anemometers, and pressure anemometers. Among them, the rotary anemometer uses the voltage generated by a small generator or rotates the moving tooth 'rotation speed to detect the wind speed. And the generators in the general anemometers are all made of iron-core generators. So, what makes the anemometer overall? It is too big, too heavy, has a large torque (eQgging-ue), and has a high speed. It can't measure the low wind speed. However, meteorological observations in remote areas are difficult to observe continuously due to long distances or poor environment. Therefore, the convenience of monitoring and control of remote meteorological measurement devices has become increasingly important. 5 201013188 [Invention] The purpose of this fx month is to provide an improved wind speed sensing device and its far, monitoring system 'reducing the manufacturing cost and the weight of the anemometer in the wind speed sensing device' to make the sensing of the anemometer more accurate The remote monitoring system allows the observer to continuously observe the wind speed in remote areas.
