Highway weather station

1. Product introduction of  highway weather station

Highway weather stations are also called highway traffic weather stations and expressway weather stations. Highway weather stations are suitable for expressway management systems and can provide accurate and reliable road traffic environmental meteorological data for the highway traffic department to guide the traffic department to make corresponding decisions. The road weather station is an integrated application of various meteorological sensors from structure to system composition by using comprehensive acquisition control technology, computer software technology, communication technology and other technologies. It can continuously obtain meteorological information along the traffic line, and can conduct real-time monitoring of meteorological elements such as visibility, wind speed, wind direction, temperature, humidity, atmospheric pressure, rainfall, and road surface conditions. Provide first-hand information for traffic-related departments to provide traffic meteorological guarantee services along the line. Based on this, it can provide timely meteorological information services for expressway safety authorities and people's travel. 

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

2. Product features of highway weather station 

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

2. Temperature, humidity, wind speed, wind direction, atmospheric pressure, piezoelectric rainfall six-element integrated sensor 

3. Wind speed and direction sensor: The top cover of the probe is hidden to avoid the interference of rain and snow accumulation and avoid natural wind blocking. The principle is to transmit continuously variable frequency ultrasonic signals, and detect the wind speed and direction by measuring the relative phase 

4. Piezoelectric rainfall: The piezoelectric rain sensor uses PVDF piezoelectric film as the rain sensing device, and distinguishes the raindrop signal through the embedded AI neural network to avoid false triggering caused by interference such as sand, dust, and vibration. 

5. Standard GPRS wireless transmission 

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