Abstract:
1. A fog removal system installed with a predetermined spacing in an area where fog regularly occurs, blowing dry air to reduce the relative humidity of atmospheric air by using the dry air, and thereby removing fog, the fog removal system comprising: a heating unit that is installed in the areas in which fog regularly occurs and heats air by using a heating part to generate the dry air; a blowing unit that is connected to the heating unit, receives the dry air generated by the heating unit, and blows the dry air into a foggy area by using a strong blowing pressure over a long range; a connection unit that connects between the heating unit and the blowing unit to transfer the dry air generated by the heating unit to the blowing unit; a light-emitting unit that is formed on a rear end portion of the blowing unit and configured to emit light by using a high luminance light-emitting diode (LED); an illuminance-detecting sensor unit that is formed on a front end portion of the blowing unit and detects illuminances of sunlight and the light generated by the light-emitting unit of the blowing unit which is spaced apart by a predetermined distance from the illuminance-detecting sensor unit; a fog removal control unit that controls the illuminance-detecting sensor unit formed on the front end portion of the blowing unit to detect the illuminances of sunlight and the light generated by the light-emitting unit formed on the rear end portion of the blowing unit of the fog removal system which is spaced apart by the predetermined distance from the illuminance-detecting sensor unit, compare detected data with preset threshold values, analyze the compared data to determine whether it is foggy, and when it is determined to be foggy, automatically drive the heating unit and the blowing unit; and a driving control unit that controls the heating unit and the blowing unit to rotate vertically and horizontally and to automatically turn on/off under the control of the fog removal control unit.
