流氷雪センサー。[Scope of Claim for Utility Model Registration] (a) Two non-contact radiation thermometers, one for measuring the water surface temperature and the other for measuring the temperature of drifting ice and snow, are used as a reference device for the sensor that detects drifting ice and snow. (b) Using the two analog output signals of the non-contact radiation thermometer, extract the temperature difference between the water surface temperature and the temperature of drifting ice and snow, and then extract only the data above a certain temperature difference, integrate the detection time of drifting ice and snow, and pass. In addition to converting this into a passing time rate within a certain fixed time and outputting a drift ice/snow detection judgment signal when the passing time ratio exceeds a certain fixed time, it also outputs a drift ice/snow detection judgment signal. An arithmetic processing unit that has the function of automatically recording the temperature difference in the second term, the accumulated time of passing through drift ice and snow, and the drift ice and snow detection signal. A practical drift ice and snow sensor with high detection performance configured as described above.
