Visibility monitoring station

1.Visibility monitoring station product introduction

Visibility monitoring station Visibility monitoring Station is used to measure visibility and monitor temperature, humidity, wind speed, wind direction, atmospheric pressure, and piezoelectric rainfall.The Visibility monitoring station is composed of several Visibility monitoring stations distributed along the highway.It automatically monitors the visibility, wind direction, wind speed, temperature, humidity, atmospheric pressure, etc.along the highway, and transmits the monitoring information to the monitoring station in a timely manner for monitoring.The traffic control system can issue warning messages in a timely manner under severe weather conditions and inform managers and drivers in a variety of ways to improve the driving level of highways.The highway weather station system consists of: weather sensors, collectors, pole brackets, power supply systems, and cloud platforms.

2.Visibility monitoring station product features

1.Visibility meter: It is composed of main components such as light transmitter, light receiver and microprocessor controller.The emitter emits infrared pulse light, and the receiver simultaneously detects the intensity of pulse light forward scattered by aerosol particles in the atmosphere.All measurement information is collected by the microprocessor controller and converted into the Meteorological Optical Range (Meteorological Optical Range) through a specialized mathematical model algorithm.MOR)

2.Six-element integrated sensor of temperature, humidity, wind speed, wind direction, atmospheric pressure and piezoelectric rainfall

3.Wind speed and direction sensor: The probe head cover is hidden to avoid interference from rain and snow accumulation and avoid obstruction by natural wind.The principle is to emit continuous variable frequency ultrasonic signals and detect wind speed and direction by measuring relative phase.

4.Piezoelectric rain: This piezoelectric rain sensor uses PVDF piezoelectric film as a rain sensing device, and uses an embedded AI neural network to distinguish raindrop signals to avoid false triggering caused by interference such as gravel, dust, vibration, etc.

5.Standard GPRS wireless transmission

6.Free choice of solar power supply and mains power supply.
