What is the working principle of the marine wind speed and direction sensor?

Wind direction wind speed sensor, as its name implies, is a tool to measure wind direction wind speed. It converts the flow velocity variable of air into a signal with a certain corresponding output signal, which can be applied to the measurement level of meteorological, military, aviation, seaport, environmental protection, industry, agriculture and forestry departments. The need for wind parameters.
In these fields of application, wind direction and wind speed are very important parameters, and the wind direction anemometer has become a universal measuring tool. The wind direction anemometer contains two sensors, a wind direction sensor and a wind speed sensor. These two sensors can work simultaneously, measuring two parameters of wind direction and wind speed.
The induction component of the wind speed sensor of the wind direction wind speed monitor is a three-cup type wind cup assembly. When the wind speed is higher than 0.4 m/s, the rotation is generated, and the signal conversion circuit is a hall integrated circuit. Under the horizontal wind driven, the wind cup group rotates, and the magnetic rod disk rotates through the main shaft. Dozens of small magnets on the magnetic pole from a plurality of rotating magnetic fields, and the pulse signal is induced by the Hall magnetosensitive element, and the frequency thereof increases with the wind speed. Large and linear increase. Calculation formula: V=0.1F; V: wind speed, unit: m/s; F: pulse frequency, unit: Hz.
The wind sensor of the wind direction wind speed monitor has a single-plate wind vane with an auxiliary target at the opposite end. The angle conversion requires a seven-digit Gray code photoelectric code disk. When the wind vane rotates with the wind, the code wheel rotates through the main shaft. Each rotation of 2.8125, seven sets of illumination and receiving optoelectronic devices located on the upper and lower sides of the code wheel will generate a new set of seven-bit parallel gray code, which will be shaped and inverted. Phase output. The azimuth-angle-Gray code-binary code comparison table is a key basis for wind direction measurement microcontroller programming.
In general, the two sensors of the wind direction wind speed monitor get the characteristics of good dynamic performance, high linear precision, high sensitivity, wide measuring range, good interchangeability and superior wind resistance.
Below we briefly introduce some of the highest performance and technical parameters of the downwind wind speed monitor.
The wind direction anemometer consists of three modes: manual, automatic and computer lock. The three modes can be established by users according to their needs. Data storage is powerful and can store up to 60,000 data. The wind direction anemometer has 32 channels of simultaneous detection, enabling multi-point synchronized detection.
