1.Product Introduction of Visibility Monitor
Visibility monitor is a weather monitoring system used to monitor and report road visibility. It can monitor multiple weather factors at the same time.Visibility monitor consists of several visibility monitoring stations distributed along the highway, which automatically monitor the visibility, wind direction, wind speed, temperature, humidity, atmospheric pressure, etc.along the highway, and transmit the monitoring information to the monitoring system in a timely manner for reference by the traffic control system.In severe weather conditions, warning information can be issued in a timely manner to inform managers and drivers in various ways to improve the driving level of the highway.Highway weather station system consists of: meteorological sensors, collectors, pole brackets, power supply systems, cloud platforms
2.Features of Visibility Monitor
1.Visibility meter: It is composed of light transmitter, light receiver and microprocessor controller.The transmitter emits infrared pulse light, and the receiver 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 meteorological optical range (MOR) through a special mathematical model algorithm.
2.Integrated sensor for six elements: temperature, humidity, wind speed, wind direction, atmospheric pressure, and piezoelectric rainfall
3.Wind speed and direction sensor: The probe cover is hidden to avoid interference from rain and snow accumulation and natural wind obstruction.The principle is to emit continuous frequency-converting ultrasonic signals and detect wind speed and direction by measuring relative phase.
4.Piezoelectric rainfall sensor: This piezoelectric rainfall sensor uses PVDF piezoelectric film as a rain sensing device, and distinguishes raindrop signals through an embedded AI neural network to avoid false triggering due to interference such as grit, dust, and vibration.
5.Standard GPRS wireless transmission
6.Solar power supply and city power supply are two power supply modes to choose freely
3.Visibility monitor technical parameters
1.Visibility: Measurement principle: aerosol forward scattering, 5m-10km (≤2km error ±2%, 2Km~10km error ±10%) Resolution: 1m
2.Wind speed: Measurement principle: ultrasonic, 0~60m/s (±0.1m/s) resolution: 0.01m/s
3.Wind direction: Measurement principle: ultrasonic, 0~360° (±2°); resolution: 1°
4.Air temperature: Measurement principle: diode junction voltage method, -40-60℃ (±0.3℃), resolution 0.01℃
5.Air humidity: Measurement principle: capacitive, 0-100%RH (±3%RH), resolution: 0.1%RH
6.Atmospheric pressure: Measurement principle: piezoresistive, 300-1100hpa (±0.25%), resolution: 0.1hpa
7.Piezoelectric rainfall: measurement principle: piezoelectric, 0-4mm/min (≤±4%), resolution: 0.01mm
