Technical Field

[0001] The utility model relates to the technical field of visibility detection equipment, in particular to a visibility data detection device. Background Art

[0002] The visibility detector can provide measurements related to meteorological visibility. The principle of the sensor is designed based on the principle of aerosol forward scattering. It is a new generation of meteorological visibility monitoring equipment developed after the transmission-type visibility meter. The visibility sensor consists of main components such as light transmitter, light receiver and microprocessor controller. The transmitter emits infrared pulse light, and the receiver simultaneously detects the intensity of the pulse light forward scattered by aerosol particles in the atmosphere. The measurement information is collected by the microprocessor controller and converted into meteorological optical visibility through a special mathematical model algorithm. Visibility sensors can be widely used in many aspects including meteorological stations, remote automatic weather stations, and transportation departments such as airports, highways, waterways, and large ships.
