基于多传感器的路面结冰检测系统

Road surface icing detecting system based on multiple sensor

路面结冰不均匀且厚度较大，由单一传感器实现结冰检测较困难。选用对薄冰敏感的压电平膜结冰传感器、可测量厚冰的光纤结冰传感器、温度传感器以及图像传感器组成一种路面结冰检测系统。系统能测量10mm以内的路面结冰，对0-5mm范围内结冰测量精度可达0．2mm，对5-10mm范围内结冰测量精度可达0．5mm。

Road surface icing is diffcult to be detected by a single sensor because it is uneven and with great thickness. A road surface icing detection system is developed, which consists of piezoelectric diaphragm icing sensors that is sensitive to thin ice, fiber-optic icing sensors that can measure thick ice, temperature sensors and image sensors. The system can detect road surface icing within 10 mm, and measurement precision can reach 0.2 mm at range of 0-5 mm and 0.5 mm at range of 5 - 10 mm.
