The invention discloses a design method of an icing sensing system for road safety early warning. The design method comprises steps of placing a sensor in a high-low temperature chamber, using a high-voltage pulsed plasma power supply to provide for the sensor with an input voltage based on set parameters under low temperature and ice-free conditions respectively, measuring a voltage value and a current value of the sensor under the temperature conditions as raw data; manually spraying water on the icing sensor to make the icing sensor to be frozen, feeding data back to a processing unit aftera signal collecting unit collects and displays the measured voltage value and current value, comparing the collected data with the corresponding raw data in real time by the processing unit; continuing to spray water on the icing sensor to obtain a series of icing thicknesses and frequencies, calibrating corresponding relationship between the obtained icing thicknesses and the voltage and the current passing through the
