1. Laser Snow Depth Monitoring Station Product Introduction

Wanxiang Company launched the WX -XS2 laser snow depth monitoring station, which uses laser snow recognition and measurement technology to overcome the shortcomings of ultrasonic, electromagnetic wave, weight and other types of sensors that cannot recognize snow, thereby achieving extremely high detection accuracy. By monitoring the distance to the location, the thickness of the snow is obtained and the snowfall per unit time is analyzed. The equipment can be used as an independent automatic snow depth monitoring alarm system, and can also be networked to form a diversified network monitoring.

Application scope: Widely used in meteorological stations, port and terminal safety monitoring, road traffic safety monitoring, aviation monitoring, construction safety monitoring, agricultural production monitoring, hydrology and water conservancy and many other fields.

Measuring principle: The snow depth sensor uses the principle of phase laser rangefinder to measure the snow depth. Phase is the frequency of the radio band. Laser ranging uses the amplitude modulation of the laser beam and measures the phase delay caused by the modulated light going back and forth on the measuring line once. Then, according to the wavelength of the modulated light, the distance represented by this phase delay is converted. That is, the time required for the light to go back and forth on the measuring line is measured indirectly, so as to solve the snow depth.
