Visibility Monitoring Instrument – A traffic visibility monitoring weather station @2022 has been updated

Visibility monitoring instrument - a traffic visibility monitoring weather station @2022 has been updated [FT-NJD10] Харагдах байдлыг хянах хэрэгсэл visibility monitoring station is composed of several visibility monitoring stations distributed along the expressway, automatic monitoring of visibility, wind direction, wind speed, temperature, humidity, atmospheric pressure, etc.
along the highway, and the monitoring information is transmitted to the monitoring in time for the reference of the traffic control system.
In bad weather conditions, warning information can be issued in a timely manner, and managers and drivers can be informed in a variety of ways to improve the driving level
of the highway.

Highway weather station system composition: weather sensor, collector, pole bracket, power supply system, cloud platform
.

Product features 1.
Visibility meter: It is composed
of main components such as light emitter, light receiver and microprocessing controller.

The emitter emits infrared pulse light, the receiver simultaneously detects the pulse light intensity of the forward scattering of aerosol particles in the atmosphere, all the measurement information is collected by the microprocessor controller and converted into meteorological optical visual range (MOR) 2.
Temperature, humidity, wind speed, wind direction, atmospheric pressure, Piezoelectric rain six-element integrated sensor 3.
Wind speed and wind direction sensor: probe the head cover to hide, to avoid the interference of rain and snow, to avoid natural wind obstruction
.

The principle is to transmit continuous frequency conversion ultrasonic signals, and detect wind speed and wind direction 4.
Piezoelectric rainfall by measuring the relative phase: The piezoelectric rainfall sensor uses PVDF piezoelectric film as a rain-sensing device, and distinguishes the raindrop signal through the embedded AI neural network to avoid false triggering
due to sand, dust, vibration and other interference.
