为了监测道路表面的结冰状况并开发有效的道路结冰预警系统,结冰传感器起着至关重要的作用,而且它必须对结冰厚度以及结冰速率非常敏感. 然而,目前国内外已有的结冰传感器还无法达到这种要求. 研发了用于道路安全预警的结冰传感器,使得道路结冰安全预警成为可能. 通过室内实验先对该道路结冰传感器进行了标定,得出了结冰厚度与结冰频率的对应关系,使其能准确的测定路面结冰厚度的具体数值;然后通过室内实验模拟路面结冰的过程,分别在不同环境温度条件下监测结冰厚度和结冰速率,得出了结冰厚度与时间的对应关系曲线,验证了其可靠性. 实验结果表明:该结冰传感器灵敏度较高,其测量精度达到0.1 mm; 能探测到结冰厚度的具体数值以及结冰速率的变化趋势,而且实验结果能够在上位机上直观地显示出来. 因此,研发的结冰传感器可以应用于道路并监测结冰厚度和结冰速率,从而为道路结冰安全预警系统的建立打下基础.
- Abstract:
-
The ice sensor plays the most important role in monitoring the icing condition of pavement surface and developing an effective warning system of icy roads, and it must be sensitive to the ice thickness and the variation of ice thickness. However, the existing ice sensor can not meet this requirement. In this study, an innovative ice sensor was developed through a special technology and it makes the warning system of icy roads possible. This sensor was calibrated first by the laboratory test and the corresponding relationship between the icing thickness and the icing frequency was obtained so that the ice thickness can be measured accurately. And then, the icing process of the road surface was simulated in the laboratory, and the relationship curve of the ice thickness with the icing time was drawn through measuring the icing thicknesses and the icing rates at different temperatures so that the reliability was verified. The results show that the ice sensor has a high sensitivity to the variation of ice thickness and the precision is better than 0.1 mm; the data of ice thickness and icing rate could be collected and presented on the upper computer directly. So this ice sensor should be available for the warning system of icy roads.
