To provide an approach notification device with low power consumption and a simple configuration.SOLUTION: An approach notification device 20 includes: an antenna 21, a transmission source identification unit 23, a notification information generating unit 24, and a notification unit 25. The antenna 21 receives high frequency signals of a plurality of communication bands. The transmission source identification unit 23 uses the frequency of the received signal to specify the type of a moving body that is the source of the received signal. The notification information generating unit 24 generates notification information including notification of the approach of the specified moving body to a specific position. The notification unit 25 sends out the notification information.SELECTED DRAWING: Figure 1
【課題】消費電力が小さく簡素な構成の接近通知装置を実現する。【解決手段】接近通知装置20は、アンテナ21、送信元特定部23、通知情報生成部24、および、通知部25を備える。アンテナ21は、複数の通信バンドの高周波信号を受信する。送信元特定部23は、受信信号の周波数を用いて、受信信号の送信元の移動体の種類を特定する。通知情報生成部24は、特定した移動体の特定位置への接近の通知を含む通知情報を生成する。通知部25は、通知情報を外部へ通知する。【選択図】 図1
