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 is an integrated application of various meteorological sensors from structure to system composition using comprehensive acquisition and control technology, computer software technology, communication technology and other technologies. It can continuously obtain meteorological information along the traffic route, and can monitor the visibility, wind speed, wind direction, temperature, humidity, atmospheric pressure, rainfall, road conditions and other meteorological elements in real time. It can complete the collection of various data through remote transmission and send them to the transportation department in time, so as to provide first-hand information for the transportation-related departments to provide transportation meteorological guarantee services along the route. On this basis, it can provide timely meteorological information services for the highway safety authorities and people's travel.

Road Weather Information System system components: meteorological sensors, collectors, pole brackets, power supply systems, cloud platforms

2. Road Weather Information System Product Features

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
