PURPOSE: An unmanned spray system capable of automatically spraying target materials in the snow or when a road is frozen is provided to obtain the safety of the road by being installed on a road habitually frozen in order to spray a deicing material in advance. CONSTITUTION: An unmanned spray system capable of automatically spraying target materials in the snow or when a road is frozen comprises a temperature sensor, a humidity sensor (212), an ultrasonic sensor (219), an infrared temperature sensor (220), a main processor, a control programming logic controller (PLC) (217), and a spraying device (218). The ultrasonic sensor measures the snowfall of the snow which newly snows and the amount of the snow cover. The infrared temperature sensor measures the temperature of the snow surface. The main processor predicts the freezing of the road and the snowfall by analyzing the measurement data from a sensor and calculates the amount of snow cover, snowfall, and the spraying amount of the target materials.
