It is supplied to the control unit 16.

FIG. 6 is a flowchart of the control section shown in FIG. In FIG. 6, ST1 to ST7 indicate steps.

Next, the control of the control unit will be described. First, the control unit 16 determines whether or not the snowfall signal is output from the snowfall sensor 12 (step ST1). If the snowfall signal is output from the snowfall sensor 12, the road surface temperature from the road surface temperature sensor 13 is the icing temperature. Then, for example, it is determined whether the temperature is 0 ° C. or lower (step ST2). If it is determined in step ST2 that the road surface temperature from the road surface temperature sensor 13 is equal to or lower than the freezing temperature, the motor-operated valve 11 is opened (step ST3), and the process returns to step ST1 to return to the snowfall signal.
Is output and the road surface temperature from the road surface temperature sensor 13 is higher than the freezing temperature, the motor-operated valve 11 is closed (step ST4), and the process returns to step ST1.

Next, if a non-snowfall signal is output from the snowfall sensor 12 in the determination of step ST1, the moisture sensor 1
It is determined whether the moisture signal from the moisture sensor 4 is a moisture detection signal (step ST5). If the moisture signal from the moisture sensor 14 is a non-moisture detection signal, the process proceeds to step ST4 and the moisture signal from the moisture sensor 14 is moisture. If it is a detection signal, it is determined whether the road surface temperature from the road surface temperature sensor 13 is equal to or lower than the freezing temperature (step ST6).

If it is determined in step ST6 that the road surface temperature from the road surface temperature sensor 13 is below the freezing temperature,
If the road surface temperature from the road surface temperature sensor 13 is higher than the freezing temperature, the process proceeds to step ST3, and it is determined whether the outside air temperature from the outside air temperature sensor 15 is below the freezing temperature (step ST7). If it is determined in step ST7 that the outside air temperature from the outside air temperature sensor 15 is below the freezing temperature, the process proceeds to step ST3, and if the outside air temperature from the outside air temperature sensor 15 is higher than the freezing temperature, the process proceeds to step ST4.

As described above, according to the second embodiment of the present invention, when the road surface temperature is equal to or lower than the freezing temperature in a weather condition in which the installation place may be in a snowy state, that is, in a snowfall state, moisture is left on the road surface. When the road surface temperature or the outside air temperature is equal to or lower than the freezing temperature in such a state, the antifreezing agent L is supplied to the frame body 1. Therefore, the antifreezing agent L can be efficiently and efficiently supplied according to the weather condition. Can be controlled.

Therefore, when the road surface temperature is below the freezing temperature in a snowfall state, it is possible not only to prevent the road surface from becoming a snow and ice state, but also to prevent the road surface from being melted by snow or raining after the snowfall. When the road surface temperature or the outside air temperature is equal to or lower than the freezing temperature in a state where rainwater or the like is accumulated in the road surface, it is possible to prevent the road surface from being frozen. Moreover, since the electric power of the solar cell 21 and the electric power of the storage battery 22 charged by the solar cell 21 are used as the drive power of the control unit 16, the electric power can be used even in a place where commercial power cannot be supplied.

The frame 1, the antifreezing agent storage tank 3, and the antifreezing agent storage auxiliary tank 4 are provided at different heights so that the antifreezing agent L can be supplied to the frame 1 by hydraulic pressure. However, the antifreezing agent L may be supplied to the frame body 1 by a pump. Further, the flow rate adjusting means is used as the flow rate adjusting valve 10.
However, the supply means and the flow rate adjusting means may be combined with the pump by using a pump capable of delivering a fixed amount or a pump capable of variably setting the delivery amount.

Further, although the freezing temperature has been described as 0 ° C., if the temperature is lower than 0 ° C. in consideration of the water purity, that is, the condition of the road surface, the altitude of the installation site, etc., the antifreezing agent can be efficiently used without waste. The supply of L can be controlled. Then, the freezing temperature of the road surface temperature sensor 13 and the outside air temperature sensor 15 are set to be the same, but considering that the outside air temperature sensor 15 is away from the road surface and that the specific heat of air is smaller than the specific heat of water, When the freezing temperature for the outside air temperature from the temperature sensor 15 is set lower than the freezing temperature for the road surface temperature from the road surface temperature sensor 13, for example, 2 ° C. to 3 ° C. lower, the supply of the antifreezing agent L is controlled more efficiently without waste. can do.

In addition, the antifreezing agent L is supplied to the frame body 1 in a weather condition where the installation place may be in a snowy state based on the outputs of the respective sensors 12 to 15.
Even if the supply of the antifreezing agent L is controlled by a timer in consideration of the traffic time zone of an automobile, or the supply of the antifreezing agent L is controlled by using the outputs of the respective sensors 12 to 15 and the timer, It is possible to obtain various effects.

Further, assuming that power shortage will occur due to lack of sunlight, etc., the motor-operated valve 11 is made to be a normally open type that is in an open state when the power is off, so that it can be used without problems even in the case of power shortage. be able to. Although the solar cell 21 and / or the storage battery 22 is used as the driving power source, it goes without saying that a commercial power source may be used as the driving power source.
