There are many problems such as ultrasonic type and optical type for meteorological observation, but they are not suitable for small-scale road heating because of the high cost due to the method.

It is a source of information for accurate control, enriching the information in the ting. In addition, the snowfall intensity meter is suitable for small-scale road heating detectors because the entire structure is simple and inexpensive because it can be realized simply by arranging electrodes, respective heaters and temperature detection elements.

ルする。The principle structure of the present invention will be described below with reference to the drawings. First
In the figure, 1 is an electrode for detecting snowfall, and 2 is a heater for melting snow. The melted water flows down,
It flows on the temperature detection element 3 of FIG. Therefore, the temperature is detected by this, and the heater of 4 is controlled so as to maintain a constant temperature.

出力が降雪強度の信号となる。In FIG. 2, an AC voltage is first applied to the first electrode. When snow falls and falls on electrode 1, when it falls, it is melted by heater 2 and the impedance between electrodes 1 decreases. As the impedance drops, an AC voltage is transmitted, which is amplified by 5 and becomes a signal indicating the presence or absence of snow.
Next, the melted water flows downward as it is, and passes over the temperature detecting element 3 described above. As a result, the temperature of that part drops and a difference from the set temperature occurs, so the differential amplifier 7 outputs 8
The heater controller of 4 is controlled to control the heater of 4 so that the temperature becomes constant. At this time, the output of the differential amplifier of 7 becomes a signal of snowfall intensity.
