The invention discloses a road operation guarantee system and an intelligent implementation method thereof. The guarantee system comprises a power generation module, a condensed ice information acquisition module, a condensed ice early warning module and a snow-melting agent spraying module. The power generation module comprises a solar panel, the condensed ice information acquisition module comprises a distributed sensor and a data processor, the condensed ice early warning module comprises an ice condensation danger level alarm, and the snow-melting agent spraying module comprises a liquid storage tank body, a filter, a centrifugal pump, an electromagnetic valve, a high-pressure spray head and an infrared sensor. The operation guarantee system has the advantages of being high in efficiency, economical, environmentally friendly, high in practicability, small in traffic interference and the like. The intelligent implementation method of the system is high in intelligent degree, real-time monitoring, multi-stage early warning, automatic triggering of the snow-melting agent and quantitative spraying of the snow-melting agent can be achieved, and the safety and smoothness of running of road infrastructures in ice and snow weather are guaranteed.
