Description
Claims (2)
- 移動体に搭載されるGPS受信機を有する送信装置から送信される位置情報データを含むマイクロ周波数帯の信号を、受信装置の回転アンテナによって受信し、受信した前記位置情報データに基づき制御装置で前記回転アンテナの方向調整を行う信号伝送システムにおいて、
受信した前記位置情報データと内蔵する高度データデータベースに基づき前記送信装置の位置および前記回転アンテナの位置の2点間の標高断面図および前記2点間の前記送信装置から送信される信号の直接波と一次フレネルゾーンを表示する手段であって、
前記送信装置が移動し所定時間後に前記一次フレネルゾーンが前記標高断面図に接触するかどうかを予測し接触すると予測した場合に注意の文字を表示するとともに、前記送信装置がさらに移動して前記一次フレネルゾーンの少なくとも一部が前記標高断面図で遮断された場合に危険の文字を表示する手段を備えることを特徴とする信号伝送システム。 - 請求項1記載の信号伝送システムにおいて、前記表示する手段は、更に、前記一次フレネルゾーンが前記標高断面図から離れているときに正常の文字を表示することを特徴とする信号伝送システム。
