Abstract

The present invention discloses a monitoring system for road ice. The system comprises an image acquisition device, a road ice detector, and a display terminal. The road ice detector comprises a road surface temperature sensor, a road surface humidity sensor, a rain sensor and a monitoring controller. The output ends of the road surface temperature sensor, the road surface humidity sensor and the rain sensor are connected to the input end of a signal switching device, and the output end of the signal switching device is connected to the input end of a filter. The output end of the filter is connected to the input end of a signal amplifier. The output end of the signal amplifier is connected to the input end of the monitoring controller through an A/D chip 10. The output end of the monitoring controller and the output end of the image acquisition device are connected to the input end of the display terminal. The monitoring system prevents error detection, once the signal controller sends a road icing signal, through the image information received in the display terminal, the icing signal and the image are combined to judge the road ice, and measures are taken timely.

Description

technical field [0001] The invention relates to a monitoring system for road icing, which belongs to the technical field of icing detection systems. Background technique [0002] If the ground temperature is lower than 0°C, snow or ice will appear on the road. Road icing tends to occur during the period from November to April of the following year (that is, winter and early spring). In northern my country, especially in the Northeast and northern Inner Mongolia, roads often freeze. [0003] Road icing warning signals are divided into three levels, which are represented by yellow, orange and red respectively. When the road surface temperature is lower than 0°C, precipitation occurs, and road icing that may affect traffic may occur within 12 hours, a yellow warning signal for road icing will be issued. At this time, drivers should pay attention to road conditions and drive safely. Pedestrians should ride bicycles as little as possible when going out, and pay attention to ...
