1、 Product Introduction
NJD50The visibility monitoring station is composed of several visibility monitoring stations distributed along the highway, which are networked to automatically monitor the visibility and current weather phenomena along the highway. The monitoring information is transmitted to the monitoring system in a timely manner for reference by the traffic control system. In adverse weather conditions, warning information can be issued in a timely manner to inform management personnel and drivers in various ways, in order to improve the driving level of the highway. In addition, it can also be added at any time according to the actual needs of users, such as temperature, humidity, wind pressure, and rain integrated meteorological stations, laser remote sensing road condition detectors, etc., to achieve multi-element meteorological observation.
The composition of the visibility monitoring station system includes visibility sensors, collectors, pole supports, power supply systems, and cloud platforms
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. Standard GPRS wireless transmission
3. Free choice between solar power supply and mains power supply
