Flood detection system

Abstract

This system provides a flood detection system that can accurately determine the presence or absence of water on the target surface and the extent of flooding. [Solution] The flood detection system 1 comprises an irradiation unit 12 that irradiates radio waves toward the detection target surface 50, a receiving unit 13 that receives reflected radio waves, and a flood detection unit 21 that detects the presence or absence of water on the detection target surface 50 based on the reflection intensity and velocity calculated from the reflected waves. The irradiation unit 12 irradiates radio waves such that the irradiation center axis L1 of the radio waves is inclined with respect to the detection target surface 50.

Claims

1. An irradiation unit that emits radio waves toward the surface to be detected, A receiving unit that receives the reflected waves of the aforementioned radio waves, The system includes a water immersion detection unit that detects the presence or absence of water on the target surface based on the reflection intensity and velocity calculated from the reflected waves, The flood detection system is characterized in that the irradiation unit irradiates radio waves such that the irradiation center axis of the radio waves is inclined with respect to the detection target surface.

2. The flood detection system according to claim 1, characterized in that it has a disturbance determination unit that determines whether or not there is disturbance in the water surface of the detection target surface based on the speed.

3. The flood detection system according to claim 1 or 2, further comprising a turbidity calculation unit that calculates the turbidity of the water on the detection target surface based on the reflection intensity.
