To provide a proximity object detection system that can detect a living object.SOLUTION: A proximity object detection system comprises a sonar for detecting presence/absence of a proximity object in a detection region and a microphone for collecting a sound produced from the proximity object. The proximity object detection system includes a controller for determining whether or not the proximity object present in the detection region produces sound based on a detection result of the sonar and a sound collection result of the microphone. This enables the system to determine that the proximity object is a living object when the detected proximity object produces the sound, and determine that the proximity object is not a living object when the detected proximity object does not produce the sound. Thus, a proximity object detection system capable of detecting the living object can be obtained.SELECTED DRAWING: Figure 3

    【課題】生物を検知可能な近接物検知システムを提供する。【解決手段】近接物検知システムは、検知領域における近接物の有無を検知するソナーと、近接物が発する音を集音するマイクとを備えている。近接物検知システムは、ソナーの検知結果とマイクの集音結果とに基づき、検知領域に存在している近接物が音を発しているか否かを判定する制御部とを備えている。このため、検知した近接物が音を発している場合には、近接物が生物であるとみなし、検知した近接物が音を発していない場合には、近接物が生物ではないとみなすことができる。したがって、生物を検知可能な近接物検知システムを得ることができる。【選択図】図3
