This application relates to the field of road de-icing technology, and more particularly to a road surface de-icing system. The road surface de-icing system includes a temperature-measuring optical fiber, a DTS (Digital Transmission System) host, a control terminal, and multiple de-icing devices. The temperature-measuring optical fiber is laid on both sides of the road surface base layer; multiple de-icing devices are installed on both sides of the road surface; the temperature-measuring optical fiber is divided into multiple temperature-measuring segments, each corresponding to one of the de-icing devices; the DTS host can acquire the temperature values ​​detected by the multiple temperature-measuring segments in real time. When the temperature value of one or more temperature-measuring segments acquired by the DTS host reaches the freezing temperature threshold, the control terminal controls the de-icing device corresponding to the temperature-measuring segment that has reached the freezing temperature threshold to activate, thereby spraying hot water onto the road surface through spray heads. The road surface de-icing system of this application solves the problems of significant misjudgment in existing road surface icing monitoring systems, the excessive cost of spraying organic de-icing agents, and the corrosive damage to roads caused by spraying inorganic de-icing agents.
