This paper introduces the design scheme of expressway pavement icing detection system, and adopts the method of combining vibration propagation, whether the temperature reaches freezing point, and the change of electrical conductivity to comprehensively judge the icing condition of the pavement. As a node in the wireless sensor network of traffic weather station, the system has the characteristics of flexible networking, low cost and low power consumption. This design includes solar floor lamp and solar LED display screen. This design adopts a facility device consisting of a solar floor lamp and a solar LED display screen. The solar floor lamp is provided with a solar photovoltaic cell, a charging and discharging cell, a red and green LED lamp, a temperature and humidity sensor and a D data processing and transmission chip circuit. The solar LED display screen is provided with a solar photovoltaic cell, a charging and discharging cell, an LED graphic display screen, a P data processing and transmission chip circuit and a red flashing warning light; According to the technical scheme that red light and graphic warning are sent out according to freezing critical data collected from the ground, and the data are transmitted to the traffic control center through the Internet, the problem and deficiency that it is difficult to issue road freezing warning in real time in the prior art are overcome, so that the expressway can issue road freezing warning in real time.
