Visibility monitoring equipment in foggy areas

Visibility monitoring equipment in foggy areas

1、 Product Introduction

The NJD50 visibility monitoring station is composed of a network 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 adverse weather conditions, it can issue warning information in a timely manner and inform management personnel and drivers in various ways to improve the driving level of the highway. The composition of the highway meteorological station system includes meteorological sensors, collectors, pole supports, power supply system, and cloud platform

2、 Product features of visibility monitoring equipment in foggy areas

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

4、 Introduction to Cloud Platform

1. CS architecture software platform, supporting direct observation through mobile and PC browsers without the need for additional software installation.

2. Support multi account and multi device login

3. Support real-time data display and historical data display dashboard

4. Cloud servers and cloud data storage are stable, reliable, easy to scale, and load balanced.

5. Support SMS alarm and threshold setting

6. Support map display and viewing device information.

7. Support data curve analysis

8. Support data export in tabular format

9. Support data forwarding, HJ-212 protocol, TCP forwarding, HTTP protocol, etc.

10. Support data post-processing function

11. Support external running of JavaScript scripts
