Smart Agriculture: Application of Wind Speed u200bu200band Direction Sensor in Agriculture
The horizontal movement of the air is called wind. Wind is a natural force. It is an extremely important meteorological factor in the process of agricultural production. The impact of wind on agricultural production is beneficial and harmful. It can benefit mankind as well as Humans cause disasters, which directly or indirectly affect agricultural production and plant growth and development. Therefore, in agricultural production activities, it is necessary to use wind speed and direction sensors to monitor the wind. Appropriate wind speed and direction can improve the farmland environment, for example, for farmland evapotranspiration, near-surface heat exchange, and transportation of carbon dioxide and oxygen in the air, these will accelerate and strengthen due to the increase of wind speed. Wind can also help the spread of pollen and seeds of plants. Many plants in nature use the power of wind to cross-pollinate and spread. The size of wind speed will affect the pollination efficiency and the distance of seed transmission, thereby affecting the reproduction and distribution of plants. A greater impact. In addition to the positive impact of wind on improving the farmland environment, wind also has a negative impact on agricultural production, spreading pathogens, causing large-scale plant diseases, helping pests to migrate, and also causing crops to fall and trees to break , The phenomenon of falling flowers and fruits. Taken together, changes in wind have their own advantages and disadvantages to agricultural production. In order to be able to respond to the impact caused by wind changes in time, the responsible agricultural personnel should use wind speed and direction sensors to monitor and make timely adjustments based on the monitoring results. The three-cup wind speed sensor and the wind direction sensor are made of polycarbonate composite materials, which have good anti-corrosion and anti-corrosion characteristics, which can ensure that the wind speed and direction sensor is used for a long time without rusting phenomenon, and at the same time cooperates with the smooth internal The bearing system ensures the accuracy of information collection. Wind direction sensorIn order to adapt to the harsh agricultural environment, the wind direction sensor has high mechanical strength and high hardness, and the structure and weight have been carefully designed and distributed. It has the characteristics of small moment of inertia and sensitive response. ; Adopt high-performance imported bearings, low rotation resistance, accurate measurement; and do anti-electromagnetic interference treatment. In order to make the measurement accurate, the wind direction sensor adopts a structure similar to a sliding rheostat. The maximum and minimum resistance values u200bu200bgenerated are marked as 360° and 0° respectively. When the wind vane rotates, the sliding rod of the sliding rheostat It will rotate with the wind vane on the top, resulting in different voltage changes, and the wind direction is obtained according to the voltage value. Three-cup wind speed sensorThe wind speed sensor is small and light, which is easy to carry and assemble. And adopts the three-cup design concept, which can effectively obtain wind speed information. The shell is made of high-quality aluminum alloy profiles, and the exterior is electroplated and sprayed. It has good anti-corrosion and anti-corrosion characteristics, which can ensure that the sensor is rust-free for long-term use This phenomenon, coupled with the smooth internal bearing system, ensures the accuracy of information collection. Wind speed and direction sensors are generally used together with agricultural weather stations; in the process of monitoring wind speed and direction in agriculture, we install the wind speed and direction sensors on the agricultural weather station to monitor the wind speed and direction, and upload the data to the weather station. After the station integrates all the weather information, it uploads the data to the environmental monitoring cloud platform through GPRS/4G, so that the person in charge of agriculture can make reasonable measures based on the data. Nowadays, wind speed and direction sensors are not only used in agricultural production. With the development of science and technology, wind direction and wind speed sensors are increasingly used in construction machinery, railways, ports, docks, power plants, meteorology, Weather monitoring of various environments such as ropeways.
