The manager may set the information regarding the salt water heating time of the heater unit 100 by manipulating the second timer.

Information on the salt water heating time of the second timer may be a salt water heating time zone or a salt water heating time interval.

When the information on the salt water heating time of the second timer is the salt water heating time zone, and the salt water heating time zone is 1 pm, 3 pm, 4 pm, 7 pm,

The control unit 90 is salt water (5) accommodated in the brine tank 320 of the brine spray unit 30, the heater unit 100 at 1 pm, 3 pm, 4 pm, 7 pm ) And the brine 5 contained in the brine tank 520 of the brine supply unit 50 can be heated.

When the information on the brine heat time of the second timer is the salt water heat time interval, the salt water heat time interval is 30 minutes,

The control unit 90 is a saltwater tank of the brine 5 and the brine supply unit 50 accommodated in the brine tank 320 of the brine spray unit 30 is the heater unit 100 every 30 minutes. It is controlled to be able to heat the brine (5) accommodated inside the (520).

Since the controller 90 controls the heater unit 100 according to the information on the salt water heating time set in the timer 180, the inside of the salt water spraying unit 30 and the salt water supply unit at a predetermined time interval or a predetermined time interval. Since the brine 5 accommodated in the inside of the heating unit 50 can be heated, as well as the control unit 90 controls the saltwater spray unit 30 according to the information on the saltwater spraying time set in the timer 180. At a predetermined time interval or at a predetermined time interval, the brine spray unit 30 may have an advantage of automatically and more easily spraying the brine 5 on the road surface 3 including a road in a tunnel.

According to the present invention configured as described above, the salt water spraying unit 30 is controlled by the control unit 90 according to the output signal of the eye sensor 150 and the temperature sensor 160, the road surface including the road in the tunnel, etc. Since it is automatically sprayed with (3) the brine (5), there is no need to spray snow removing agent or thawing agent manually on the road surface, in particular, according to the output signal of the water level detection unit 310 and the concentration detection unit 330 The brine spray unit 30 because the brine supply unit 50 and the water supply unit 70 supplies the brine (5) and water (7) into the brine spray unit 30 by the control of the controller 90. There is an advantage that the concentration of brine 5 in the water can be kept constant.
