Zusammenfassung:PROBLEM TO BE SOLVED: To provide a geomagnetic information transfer device which is excellent in noise countermeasures, and capable of transferring even data other than geomagnetic information such as environment monitoring information.SOLUTION: A geomagnetic information transfer device 4 at a transmission side optically converts geomagnetic information detected in buildings B, C at the transmission side. A geomagnetic information transfer device 6 at a reception side receives an optical signal in a building A at a reception side, and converts the optical signal into geomagnetic information in the building A at the reception side. An optical cable 10 connects the geomagnetic information transfer device 4 at the transmission side to the geomagnetic information transfer device 6 at the reception side. The geomagnetic information transfer device 4 at the transmission side comprises a frame assembly circuit for assembling environment information and the geomagnetic information detected in the buildings B, C at the transmission side in one frame signal. The geomagnetic information transfer device 6 at the reception side comprises: a frame processing circuit for separating the geomagnetic information and the environment information from the received frame signal, and for outputting them; a collection device 7 for collecting the geomagnetic information output from the frame processing circuit; and a collection device 8 for collecting the environment information output therefrom.SELECTED DRAWING: Figure 1 【課題】ノイズ対策に優れ、環境監視情報などの地気情報以外のデータも転送可能な地気情報転送装置を提供する。【解決手段】送信側の地気情報転送装置4は、送信側の建物B、C内で検出された地気情報を光変換する。受信側の地気情報転送装置6は、受信側の建物A内で光信号を受信して、受信側の建物A内の地気情報へ変換する。光ケーブル10は、送信側の地気情報転送装置4と受信側の地気情報転送装置6を接続する。送信側の地気情報転送装置4は、送信側の建物B、C内で検出された環境情報と地気情報を1つのフレーム信号内に組み込むフレーム組立回路を備える。受信側の地気情報転送装置6は、受信したフレーム信号から地気情報と環境情報を分離して出力するフレーム処理回路と、フレーム処理回路から出力された地気情報の収集装置7と、環境情報の収集装置8を備える。【選択図】図1
