The present invention relates to a spray device of spraying a liquid or granule antifreeze substance onto a road surface while a spray unit reciprocates in a direction of a road, wherein the spray device with the spray unit is located on the road surface, and an antifreeze system capable of thawing or preventing freezing in a freezing section by using the spray device and helping safe driving by informing a driver of various kinds of information on the freezing section. To achieve the purpose, a moving type antifreeze substance spray device comprises: a bottom support having an upper opening in the longitudinal direction and installed along the road surface; a top support mounted on the upper part of the bottom support; a nozzle unit installed in the bottom support and the top support and including a spray nozzle for discharging the antifreeze substance; an antifreeze substance supply unit for the spray nozzle of the nozzle unit; and a driving unit enabling the nozzle unit to linearly reciprocate in the longitudinal direction of the top support. According to the present invention, the antifreeze system using the moving type antifreeze substance spray device comprises: the spray device and a freezing sensor, installed in the freezing section on a road; a vehicle entry sensor, a freezing section guide, and spray device operation display device, which are individually installed at the front and rear of a front freezing section located on the front side of the freezing section of the road; a vehicle access sensor installed in a rear freezing section located on the rear side of the freezing section of the road; and a main controller controlling the display device and the driving unit of the spray device according to each sensing value of the freezing sensor, the vehicle entry sensor, and the vehicle access sensor. |
