Technical Field
[0001] This invention belongs to the field of intelligent road traffic safety equipment, specifically relating to an integrated device based on solar energy, which automatically detects fog and icing, uses hot air to defog and melt ice, and remotely monitors the process. Background Technology
[0002] Fog patches and icy roads are common causes of traffic accidents on highways and mountain roads.
[0003] Traditional defogging and de-icing methods rely on manual salting and road closures, which are inefficient, costly, and pollute the road surface.
[0004] The mains power wiring is complex, and it cannot be widely used in remote sections of roads, bridges, and mountainous areas. Summary of the Invention
[0005] Solar-powered intelligent defogging, de-icing, and warning system for road surfaces, including:
[0006] Solar power supply and energy storage modules;
[0007] Multi-sensor fusion detection module (temperature and humidity, visibility, road surface temperature, icing);
[0008] PTC hot air defogging and de-icing execution module;
[0009] Automatic warning yellow light module;
[0010] 4G / 5G remote data and video backhaul module;
[0011] The equipment collects environmental parameters in real time. When it detects heavy fog or icy roads, it automatically turns on the heater and warning lights, and uploads the data and images to the control center, achieving fully automatic, unattended, and large-scale networked road safety assurance.
[0012] Innovation
[0013] It is powered independently by solar energy, requiring no external mains power, and is suitable for all road sections;
[0014] Multi-sensor fusion judgment ensures accurate startup, energy efficiency, and stable operation;
[0015] Hot air directional defogging and de-icing does not corrode road surfaces and produces no chemical pollution;
[0016] It combines warning, defogging, and monitoring functions, with a single unit covering a range of 10–20 meters.
[0017] Multiple units can be networked together to form a continuous anti-fog and anti-icing zone, and remote monitoring is supported.
[0018] Beneficial effects
[0019] Significantly reduce the accident rate in foggy weather and on icy roads;
[0020] Fully automated operation, zero human intervention cost;
[0021] Green and energy-saving, with no environmental pollution;
[0022] Simple to install and easy to maintain, suitable for highways, bridges, mountain roads and other scenarios. Attached Figure Description

[0024] 1. Product Introduction
[0025] This product is a solar-powered, fully automatic road safety device that can automatically detect fog, road icing, and frost. It uses a hot air system to eliminate fog and melt thin ice, and warns vehicles to slow down with a yellow light. At the same time, it uploads environmental data and real-time images to a remote control center.

[0038] The system uses a combination of temperature and humidity, visibility, road surface temperature, and icing sensors for assessment.
[0039] Automatic hot air defrosting and de-icing
[0040] The heated air outlet blows directly onto the road surface, quickly raising the near-ground temperature, evaporating fog, and melting thin ice.
[0041] Automatic Alarm
[0042] In foggy or icy conditions, the yellow light will automatically flash to remind vehicles to slow down.
[0043] Remote monitoring
