In the field of highway safety, fog masses can be regarded as the most dangerous "invisible killers". This kind of local thick fog often appears suddenly, and visibility can drop sharply within a hundred meters to less than ten meters, which is very likely to cause chain rear-end collisions. The emergence of the fog cluster early warning and monitoring system has provided a technological solution to this problem, giving highway managers the initiative to combat fog clusters for the first time.

The core technology of the WX-NJD10 fog warning and monitoring system lies in its precise visibility capture capability. Through intelligent monitoring nodes set up along the road, the system can sense the concentration changes of suspended particles in the air in real time. When a rapid decline in visibility is detected on a certain section of the road, the system will immediately activate a multi-level early warning mechanism. Unlike the large-scale monitoring of traditional meteorological stations, this system is extremely sensitive to local microclimate changes and is particularly adept at capturing sudden meteorological phenomena such as fog clusters.

The way early warning information is transmitted reflects the intelligent design of the system. Monitoring data is transmitted in real time to the command center via optical fiber networks, and is simultaneously released through multiple channels along the line, such as electronic information boards and navigation apps. When a cloud of fog forms, the system will automatically trigger a speed limit prompt and a danger warning, allowing the driver sufficient time to adjust their speed. Some advanced systems can also be linked with the fog zone anti-collision system, automatically turning on the guide lights and contour markers to provide visual driving guidance for vehicles.

The deployment strategy of the system is also quite ingenious. Monitoring points are usually set up on sections with a high incidence of fog clusters, and the spacing is scientifically planned according to the terrain features. Monitoring networks will be denser and more densely deployed in areas prone to occurrence such as mountain Bridges and river valleys, forming a comprehensive monitoring network without blind spots. Each monitoring node has been designed for environmental adaptability, capable of withstanding the invasion of severe weather conditions such as strong winds and heavy rain, ensuring long-term stable operation.
