(Summary description)   　　Application of wind power   　　In order to make better use of wind resources in modern large-scale wind turbines, the direction of the impeller is usually not controlled by the tail, but the angle is controlled by the wind direction sensor. Usually the wind direction sensor needs to be installed on the top of the wind turbine. It is necessary to prevent the impeller from obstructing the measurement of the sensor. If the height of the sensor reaches a certain level, people also need to pay attention to lightning protection and leakage protection for the generator set and the sensor.   　　Usually wind direction sensors installed near wind farms have the following two main purposes:   　　1. Ensure that the wind turbine blades can face the wind direction angle in real time to ensure that the facts are in normal working condition.   　　2. The wind direction measuring instrument on the weather station equipment near the wind farm can ensure that the windy weather will not pose a threat to the wind turbine.   　　Application on tower crane   　　Generally, in order to ensure the progress of construction projects, most tower cranes are usually equipped with wind speed sensor equipment. Its existence allows the crane to issue an alarm when the high wind affects the crane's work, but when the high wind has begun to affect the crane's work, It is often necessary to pay attention to the change of wind direction, so as to respond to the wind of different wind directions, so some cranes have already used wind direction sensor equipment.   　　Pay attention to installing wind direction sensor   　　1. Since the height of the tower crane is usually above 20 meters, personal safety should be paid attention to during the installation of the wind direction sensor.   　　2. The wind direction sensor installed on the tower crane should be at the same height as the wind speed alarm.   　　3. The installed wind direction sensor should avoid some obstacles on the tower crane as much as possible.   　　4. After the sensor is installed, a dedicated maintenance work should be established.   　　Application in coal mine   　　The ventilation equipment installed in the mine often has different models and different working powers. Therefore, it is necessary to use wind speed sensor equipment to monitor the wind speed value of each ventilation duct to prevent the ventilation rate of a certain location from being too low. The phenomenon that the concentration of harmful gases is too high appears.   　　In fact, in order to ensure the safety of production work in large, medium and small coal mines, according to relevant regulations, wind speed sensor equipment should be installed in coal mines, and wind speed sensor equipment should be installed in every mining area, wing return airway and total return airway. , And the tunneling face is part of the mining area, so the tunneling face needs to be installed with a wind speed sensor.   　　The tunneling face is more prone to harmful gases   　　In fact, there is another main reason why wind speed sensors need to be installed in the tunneling face. Generally, harmful gases such as methane, carbon monoxide, and gas in coal mines often appear from the tunneling face with the greatest probability, and some gases are even in the “gas chambers” formed underground. The gas is directly some harmful gas, so it is necessary to install wind speed sensors and connect ventilation equipment at every position in the coal mine.   　　Meteorological applications   　　In the field of meteorology, it is usually necessary to observe many natural phenomena, such as changes in wind speed and weather, and of course changes in wind direction. For the measurement of wind direction, wind direction meters or wind direction sensor equipment are basically used to solve this problem.   　　Measurement of changes in surface wind direction: In the control of wind and sand in deserts and plateau areas, people usually need to pay attention to changes in the speed and direction of airflow, so that more meteorological data can be grasped, and a more complete control plan can be formulated at the same time. Meteorological equipment such as a wind direction sensor is used throughout the process.   　　Marine storm warning: It can be said that the marine weather warning system is one of the important applications of wind direction sensors in the meteorological field. The wind direction change data provided by the marine weather warning system is one of the important parameters for predicting the coverage of typhoons and the "operation" trajectory.
