The traffic visibility monitoring meteorological station can monitor key parameters such as particulate matter concentration, humidity, temperature in the air in real time, and quickly calculate the current visibility situation of the road. Once visibility is detected to be below the safety threshold, warning information will be immediately issued.

1. Traffic visibility monitoring meteorological station Product Introduction

The WX-NJD 1 0 visibility monitoring station is composed of several visibility monitoring stations distributed along the highway. It automatically monitors the visibility, wind direction, wind speed, temperature, humidity, atmospheric pressure, etc. along the highway, and transmits the monitoring information to the monitoring system in a timely manner for reference by the traffic control system. In severe weather conditions, it can issue warning information in a timely manner and inform managers and drivers in various ways to improve the driving level of the highway. Highway weather station system composition: meteorological sensor, collector, pole bracket, power supply system, cloud platform

2.Traffic visibility monitoring meteorological station  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
