Road Weather Information System

1.Road Weather Information System Product Introduction

Road Weather Information System monitors the road environment and provides visibility, wind speed, wind direction, temperature, humidity, atmospheric pressure, rainfall and other data.Road Weather Information System uses integrated applications of various meteorological sensors from structure to system composition using integrated acquisition and control technology, computer software technology, communication technology and other technologies.It can continuously obtain meteorological information along the traffic route, can conduct real-time monitoring of meteorological elements such as visibility, wind speed, wind direction, temperature, humidity, atmospheric pressure, rainfall, road conditions, etc., and summarize various data through remote transmission and promptly transmit it to the transportation department, providing first-hand information for transportation related departments to provide meteorological guarantee services along the traffic route.Based on this, timely meteorological information services can be provided for highway safety authorities and people's travel.

Road Weather Information System system composition: visibility sensor, remote sensing road condition sensor, weather sensor, collector, pole bracket, power supply system, cloud platform

2.Road Weather Information System product features

1.Visibility meter: consists of main components such as light emitter, light receiver and microprocessor controller.The transmitter emits infrared pulsed light, and the receiver simultaneously detects the pulse light intensity of forward scattered aerosol particles in the atmosphere.All measurement information is collected by the microprocessor controller and converted into meteorological optical range through a special mathematical model algorithm.

2.Integrated sensor with six elements: temperature, humidity, wind speed, wind direction, atmospheric pressure, and piezoelectric rainfall

3.Wind speed and wind direction sensor: The cover of the probe is hidden to avoid interference from rain and snow accumulation, and to avoid natural wind obscurity.The principle is to transmit a continuous frequency conversion ultrasonic signal, and to detect the wind speed and direction by measuring the relative phase.

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

5.Standard GPRS wireless transmission

6.Free choice of two power supply methods: solar power supply and mains power supply
