Use of a wind speed and direction sensor
Although the wind direction sensor and the wind speed sensor are two completely independent sensors, in most cases, these two sensors are integrated in the same measuring device, and play a role together by comprehensively processing data information.
Application of Wind Direction and Wind Speed Sensor in Meteorological Field
In the field of meteorology, it is usually necessary to observe many kinds of 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 instruments or wind direction sensor equipment are basically used to solve this problem.
Measurement of ground wind direction changes: In the sand control work in deserts and plateau areas, people usually need to pay attention to the changes in the speed and direction of the air flow, so that more meteorological data can be obtained, and a more complete control plan can be formulated, so meteorological equipment such as wind direction sensors are used throughout the process.
Marine storm early warning: It can be said that the marine meteorological early warning system is one of the important applications of wind direction sensors in the meteorological field. The wind direction change data it provides for the marine meteorological early warning system is one of the important parameters for predicting typhoon coverage and "operation" trajectory.
Application of wind direction and speed sensor in coal mine field
Ventilation equipment installed in mines often has different models, and their working power also has a large difference. Therefore, it is necessary to use wind speed sensor equipment to monitor the wind speed value of each ventilation channel to prevent the phenomenon that the ventilation rate of a certain position is too low and the concentration of harmful gases is too high.
In fact, in order to ensure the safe production of 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 each mining area, wing return air lane and total air return lane, and the excavation face is part of the mining area, so the excavation work face needs to be installed with wind speed sensors.
In fact, there is another main reason why wind speed sensors need to be installed in the tunneling surface, that is, methane, carbon monoxide, gas and other harmful gases in coal mines often have the highest probability of appearing from the tunneling surface, and even the gas in the "gas chamber" formed underground by some gases is directly some harmful gases, so it is necessary to install wind speed sensors and connect ventilation equipment at every location in the coal mine.
Application of wind direction and speed sensor in wind power generation field
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 by the wind direction sensor. Usually the wind direction sensor needs to be installed on the top of the wind turbine, but it is necessary to prevent the impeller from obstructing the sensor for measurement. If the height of the sensor reaches a certain level, people also need to pay attention to lightning protection and leakage prevention for the generator set and the sensor.
Generally, wind direction sensors installed near wind farms have the following two main purposes:
1. Ensure that the blades of the wind turbine can face the wind direction in real time, and ensure that everything is 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 of Wind Direction and Wind Speed Sensors in the Field of Tower Cranes
Usually, 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 send an alarm when the strong wind affects the crane’s work. However, when the strong wind has begun to affect the crane’s work, it is often necessary to pay attention to the change of the wind direction, so as to respond to wind in different wind directions. Therefore, some cranes have used wind direction sensor equipment.
Application of Wind Direction and Wind Speed Sensors in the Field of Air Conditioning and Ventilation Equipment
The variable air volume terminal unit is one of the main equipment of the variable air volume air conditioning system. The wind speed sensor is a key component of the variable air volume terminal device. Therefore, the type and performance of the wind speed sensor directly affect the detection and control quality of the system air volume. At present, the variable air volume terminal devices of manufacturers in my country, Europe and the United States all use pitot tube wind speed sensors, while most Japanese manufacturers do not use pitot tube wind speed sensors.
