Visibility monitor

1.Introduction to Visibility monitor products

Visibility monitor measures the transparency of the atmosphere. It is an instrument that measures the visible distance in the atmosphere and is commonly used on highways.The NJD10 Visibility monitor consists of several Visibility monitors distributed along the expressway.It automatically monitors the visibility, current weather phenomena, etc.along the expressway, and promptly transmits the monitoring information to the monitoring for reference for the traffic control system.It can issue warning information in a timely manner under harsh weather conditions, and informs managers and drivers in various ways to improve the driving level of the expressway.In addition, it can also be added at any time according to the actual needs of users: temperature, humidity, wind, pressure and rain integrated meteorological stations, laser remote sensing road condition detectors, etc.to achieve multi-factor meteorological observation.

Visibility monitor system composition: visibility sensor, collector, pole bracket, power supply system, cloud platform

2.Visibility monitor 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.Standard GPRS wireless transmission

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

3.Visibility monitor technical parameters

Visibility: Principle of measurement aerosol prescattering, 5m-10km (≤2km ±2%2km~10km ±5%>10km ±10%) resolution 1m
