WIPO Patent Application WO/2021/220799
Kind Code:
A1
Abstract:
In the present invention, an environment system (1) detects a temperature distribution and/or a windspeed distribution in a target space (S), the system comprising: a soundwave transmission unit (10) that transmits soundwaves for detection to the target space (S); a soundwave receiving unit (20) that receives the soundwaves for detection transmitted by the soundwave transmission unit (10); and a control unit (30) that controls the soundwave transmission unit (10). The control unit (30) executes a first control for adjusting the sound volume and/or the frequency of the soundwave for detection transmitted by the soundwave transmission unit (10), so that the sound volume of the soundwave for detection received by the soundwave receiving unit (20) reaches or exceeds a prescribed reference reception sound volume.
