Highway meteorological stations help promote sustainable development in the transportation industry

1、 Product Introduction

Highway meteorological station is an integrated application of various meteorological sensors from structure to system composition using comprehensive collection and control technology, computer software technology, communication technology, and other technologies. Being able to continuously obtain meteorological information along the transportation route, real-time monitoring of meteorological elements such as visibility, wind speed, wind direction, temperature, humidity, atmospheric pressure, rainfall, and road conditions can be achieved. Through remote transmission, various data can be summarized and transmitted in a timely manner, providing first-hand information for transportation related departments to provide transportation meteorological support services along the route. Based on this, timely meteorological information services can be provided for highway safety authorities and people's travel.

The composition of the highway meteorological station system includes meteorological sensors, collectors, pole supports, power supply system, and cloud platform

2、 Product Features

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

2. Six element integrated sensor for 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 accumulated rain and snow, and to avoid natural wind obstruction. The principle is to emit continuous variable frequency ultrasonic signals and detect wind speed and direction by measuring relative phase

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

5. Standard GPRS wireless transmission

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