Description

本発明は、山頂等に設置されたＦＰＵ等の受信基地局(受信装置)の回転パラボラアンテナをヘリコプタ等の移動する送信装置の方向へ遠隔制御で方向調整する装置であり、特にヘリコプタの飛行経路計画の支援に関する情報を取得及び表示させる機能に関するものである。   The present invention is a device for adjusting the direction of a rotating parabolic antenna of a receiving base station (receiving device) such as an FPU installed at a mountaintop or the like by remote control in the direction of a transmitting device such as a helicopter, and more particularly a flight path of a helicopter The present invention relates to a function for acquiring and displaying information related to planning support.

従来のＦＰＵ等の受信基地局の回転パラボラアンテナのＧＰＳ追尾は、１秒間隔で送られてくるヘリコプタのＧＰＳ位置情報(緯度、経度、高度)と受信基地局位置情報により、回転パラボラアンテナの向く方向をパソコンにより計算し、自動的に方向調整、制御する方式をとっていた。
しかし、この方法によると、運行時のヘリコプタ方向への制御はできたが、過去の飛行実績による運行注意経路（ヘリコプタと基地局をむすぶ電波伝送経路に障害物があり伝送できないポイント等）の判断ができなかった。また、運行経路の確認ができなかった。
特開２００３−７８４６７号公報 GPS tracking of a rotating parabolic antenna of a receiving base station such as a conventional FPU is suitable for a rotating parabolic antenna based on the GPS position information (latitude, longitude, altitude) and receiving base station position information of a helicopter sent at 1-second intervals. The direction was calculated by a personal computer and automatically adjusted and controlled.
However, according to this method, control in the direction of the helicopter during operation was possible, but determination of the operation caution route (points that cannot be transmitted because there are obstacles in the radio transmission path connecting the helicopter and the base station) based on past flight results. I could not. Also, the operation route could not be confirmed.
JP 2003-78467 A

従来の方式ではヘリコプタのＧＰＳ位置情報を基に自動的に受信基地局の回転パラボラアンテナを回転させることはできるものの、電波伝送経路障害物などを考慮した、事前飛行経路計画ができないため、電波伝送経路上の障害物などにより、放送中、または収録中に映像がとぎれる可能性があった。この問題を回避するために事前の飛行試験を実施する場合もあるが、ほとんどの場合は飛行しながら受信状況を確認しなければならないものであった。
本発明はこれらの欠点を除去し、受信基地局の地図表示画面上に飛行軌跡と受信状態を表示することで、電波伝送経路上の障害物などを考慮した、事前飛行経路計画が立てられるようにすることを目的とする。 Although the conventional system can automatically rotate the rotating parabolic antenna of the receiving base station based on the GPS position information of the helicopter, it does not allow for pre-flight path planning that takes into account obstacles in the radio transmission path. There was a possibility that the video was interrupted during broadcasting or recording due to obstacles on the route. In order to avoid this problem, a preliminary flight test may be performed, but in most cases the reception status must be confirmed while flying.
The present invention eliminates these disadvantages and displays a flight trajectory and a reception state on the map display screen of the receiving base station, so that a prior flight path plan can be made in consideration of obstacles on the radio wave transmission path. The purpose is to.

本発明は上記目的を達成するため、受信装置側の回転パラボラアンテナを移動する送信装置の方向へ遠隔制御装置側から方向調整する遠隔制御システムにおいて、上記移動する送信装置の夫々の位置情報及び該夫々の位置情報に対応する受信状態を上記遠隔制御装置で取得しデータ化して記憶媒体に保存し、該保存したデータを基に、上記遠隔制御装置の表示部の表示画面上に上記移動する送信装置軌跡と対応する受信状態を表示する遠隔制御システムである。
また、移動する送信装置はＦＰＵ送信部、ＧＰＳ受信機を有するヘリコプタであり、受信装置はヘリコプタからの送信信号、ＧＰＳ位置情報を受信し、ヘリコプタの夫々の位置情報及び該夫々の位置情報に対応する受信状態を抽出し、遠隔制御装置に伝送するものであり、遠隔制御装置は伝送されたヘリコプタの位置情報に基づき受信装置側の回転パラボラアンテナを遠隔制御する手段と、記憶媒体に保存されたヘリコプタの夫々の位置情報及び該夫々の位置情報に対応する受信状態データに基づき表示部の地図表示画面上にヘリコプタの飛行軌跡と対応する受信状態を表示するものである。
このように、パラボラアンテナをヘリコプタの方向に向くようＧＰＳ追尾制御する場合、ヘリコプタの位置情報(緯度、経度、高度)及び受信状態(例えば、受信電界値、ビットエラー率、マージン)をデータ化してハードディスクなどの記憶媒体に保存し、保存したデータを基に、表示部の表示画面上に飛行軌跡と受信状態を表示することにより、例えば、特定の基地局に関する最適な飛行経路の事前計画を立てるに際し、表示画面の平面地図上で、最適な飛行経路が目視確認できる。 In order to achieve the above object, the present invention provides a remote control system that adjusts the direction of a transmitting device that moves a rotating parabolic antenna on the receiving device side from the remote control device side. The reception state corresponding to each position information is acquired by the remote control device, converted into data, stored in a storage medium, and the moving transmission on the display screen of the display unit of the remote control device based on the stored data It is a remote control system which displays the receiving state corresponding to an apparatus locus.
The moving transmission device is a helicopter having an FPU transmission unit and a GPS receiver. The reception device receives a transmission signal and GPS position information from the helicopter, and corresponds to each position information of the helicopter and each position information. The reception state is extracted and transmitted to the remote control device. The remote control device is a means for remotely controlling the rotating parabolic antenna on the receiving device side based on the transmitted position information of the helicopter, and is stored in a storage medium. The reception state corresponding to the flight trajectory of the helicopter is displayed on the map display screen of the display unit based on the position information of each helicopter and the reception state data corresponding to the position information.
Thus, when GPS tracking control is performed so that the parabolic antenna faces the helicopter, the helicopter position information (latitude, longitude, altitude) and reception status (for example, received electric field value, bit error rate, margin) are converted into data. Save the data to a storage medium such as a hard disk. Based on the saved data, display the flight trajectory and reception status on the display screen of the display unit, for example, to plan in advance the optimal flight path for a specific base station In this case, the optimum flight path can be visually confirmed on the plane map on the display screen.

本発明によれば、ＦＰＵ等の受信基地局の回転パラボラアンテナをヘリコプタ等の送信側の方向へ遠隔制御で方向調整する場合、地図表示画面上でヘリコプタの飛行軌跡と受信状態が目視確認できるため、電波伝送経路上の障害物などにより、放送中、または収録中に映像が途切れるかもしれないといった操作者の不安を極力低減できる。また、映像品質を保ちながら方向調整できるよう事前に最適な飛行経路計画を立てることができる。   According to the present invention, when the direction of a rotating parabolic antenna of a receiving base station such as an FPU is adjusted by remote control in the direction of a transmitting side such as a helicopter, the flight trajectory and reception state of the helicopter can be visually confirmed on the map display screen. In addition, the operator's anxiety that the video may be interrupted during broadcasting or recording due to obstacles on the radio wave transmission path can be reduced as much as possible. In addition, an optimal flight route plan can be made in advance so that the direction can be adjusted while maintaining the video quality.

次に、本発明による信号伝送システムの動作を説明する。テレビ放送局では、取材用の撮影カメラ１２、撮影した映像等の送信信号１６を伝送するためのＦＰＵ等の送信部１３をヘリコプタ１１に搭載している。また、このヘリコプタ１１に搭載した送信部１３から送信される送信信号１６を受信するため、見通しの良い山頂あるいは高層ビル屋上などに設置された受信基地局２に、受信部２２、上下左右方向に受信角度を制御することができる回転パラボラアンテナ２１を備えており、この受信基地局２を中心とした周囲一円から送信信号を受信できるようにしている。
所要の位置に移動するヘリコプタ１１に搭載した送信部１３は、ＧＰＳ受信機１４で受信したＧＰＳ信号から算出したヘリコプタ１１の現在位置を表す、緯度、経度、高度等の位置情報のＧＰＳデータ信号１７と、撮影カメラ１２で撮影した映像等の送信信号１６を、順次送信アンテナ１５から受信基地局２の受信部２２へ送信する。
受信基地局２では、順次、送信される送信信号を回転パラボラアンテナ２１で受信し、受信信号を受信部２２へ出力する。受信部２２は、順次、入力される受信信号から、映像信号とＧＰＳ情報(ヘリコプタ１１の位置情報)を復調する。また受信部２２では、受信信号から受信基地局２における時々刻々の電波伝搬の受信状態を表す受信電界値、ビットエラー率、受信限界までのマージンを、順次算出する。
また、受信基地局２では、後述する遠隔制御装置３からのパラボラアンテナ制御信号３８を、データ通信処理部３４、２４を介してパラボラアンテナ制御処理部２３に供給し、パラボラアンテナ制御処理部２３により、回転パラボラアンテナ２１の位置及び角度を、送信装置１の方位に正確に合わせる制御を行う。
受信部２２で復調された映像信号、ＧＰＳ情報、および受信電界値、ビットエラー率、マージン情報は、受信基地局２と、例えば放送局のマスタ(主調整室)とを結ぶ専用の伝送回線(例えば同軸回線、光ファイバ回線)を使用し、マスタに設けた、例えば映像処理センタの遠隔制御装置３へ、順次、伝送される。 Next, the operation of the signal transmission system according to the present invention will be described. In the television broadcasting station, the helicopter 11 includes a shooting camera 12 for news gathering and a transmission unit 13 such as an FPU for transmitting a transmission signal 16 such as a shot video. In addition, in order to receive the transmission signal 16 transmitted from the transmission unit 13 mounted on the helicopter 11, the reception unit 22 is installed in the reception base station 2 installed on the mountaintop or high-rise building with a good view in the vertical and horizontal directions. A rotating parabolic antenna 21 capable of controlling the reception angle is provided, and a transmission signal can be received from one circle around the reception base station 2.
The transmission unit 13 mounted on the helicopter 11 moving to a required position is a GPS data signal 17 of position information such as latitude, longitude, altitude, etc., representing the current position of the helicopter 11 calculated from the GPS signal received by the GPS receiver 14. Then, a transmission signal 16 such as an image captured by the imaging camera 12 is sequentially transmitted from the transmission antenna 15 to the reception unit 22 of the reception base station 2.
The receiving base station 2 sequentially receives transmission signals to be transmitted by the rotating parabolic antenna 21 and outputs the received signals to the receiving unit 22. The receiving unit 22 sequentially demodulates the video signal and GPS information (position information of the helicopter 11) from the input reception signal. The receiving unit 22 sequentially calculates a reception electric field value indicating a reception state of radio wave propagation at the reception base station 2 from the received signal, a bit error rate, and a margin to the reception limit.
In addition, the receiving base station 2 supplies a parabolic antenna control signal 38 from the remote control device 3 to be described later to the parabolic antenna control processing unit 23 via the data communication processing units 34 and 24, and the parabolic antenna control processing unit 23 Then, control is performed to accurately match the position and angle of the rotating parabolic antenna 21 with the orientation of the transmitter 1.
The video signal demodulated by the receiving unit 22, GPS information, the received electric field value, the bit error rate, and the margin information are a dedicated transmission line (for example, connecting the receiving base station 2 and, for example, the master (main adjustment room) of the broadcasting station). For example, a coaxial line or an optical fiber line is used, and the data is sequentially transmitted to, for example, the remote control device 3 of the video processing center provided in the master.

遠隔制御装置３は、受信基地局２から順次伝送される映像信号、音声信号を、そのまま他の回路へ出力するとともに、ＧＰＳ情報がＧＰＳ情報抽出処理部３３に順次入力され、受信電界値、ビットエラー率、マージン情報が、受信電界値、ビットエラー率、マージン抽出処理部３４に、順次、入力される。
ＧＰＳ情報抽出処理部３３は、受信基地局２より順次伝送されるＧＰＳ情報から、ヘリコプタ１１の現在位置を表す、緯度、経度、高度データを抽出し、抽出した緯度、経度、高度データに基づき、ヘリコプタ１１の現在位置の座標計算処理を行い、座標計算処理により算出したヘリコプタ１１の現在位置のデータを順次、記録媒体３６に蓄積するとともに、パラボラアンテナ角度計算処理部３５、表示部３７へ出力する。
受信電界値、ビットエラー率、マージン抽出処理部３４は、受信基地局２から順次伝送されるヘリコプタ１１の現在位置での受信電界値、ビットエラー率、マージン情報を抽出し、抽出したヘリコプタ１１の現在位置における受信状態を表す、受信電界値、ビットエラー率、マージン情報を記録媒体３６に順次蓄積するとともに、表示部３７へ出力する。
角度情報抽出部３２は、受信基地局２のパラボラアンテナ制御処理部２３からデータ通信処理部２４、３４を介して伝送されるパラボラアンテナ２１の現在の角度情報を抽出し、パラボラアンテナ角度計算処理部３５へ出力する。
パラボラアンテナ角度計算処理部３５では、ＧＰＳ情報抽出処理部３３から入力されるヘリコプタ１１の現在位置のデータと角度情報抽出部３２から入力されるパラボラアンテナ２１の現在の角度情報に基づき、パラボラアンテナ２１の方位と仰角あるいは俯角を制御するパラボラアンテナ制御信号３８を生成し、データ通信処理部３１、２４を介してパラボラアンテナ制御処理部２３へ伝送する。そして、パラボラアンテナ制御処理部２３は、伝送されてきた制御信号に基づき、パラボラアンテナ２１の方位と仰角あるいは俯角を制御する。 The remote control device 3 outputs the video signal and the audio signal sequentially transmitted from the receiving base station 2 to other circuits as they are, and the GPS information is sequentially input to the GPS information extraction processing unit 33, and the received electric field value, bit The error rate and margin information are sequentially input to the received electric field value, the bit error rate, and the margin extraction processing unit 34.
The GPS information extraction processing unit 33 extracts latitude, longitude, and altitude data representing the current position of the helicopter 11 from GPS information sequentially transmitted from the receiving base station 2, and based on the extracted latitude, longitude, and altitude data, The coordinate calculation process of the current position of the helicopter 11 is performed, and the data of the current position of the helicopter 11 calculated by the coordinate calculation process is sequentially stored in the recording medium 36 and output to the parabolic antenna angle calculation processing unit 35 and the display unit 37. .
The reception electric field value, bit error rate, and margin extraction processing unit 34 extracts the reception electric field value, bit error rate, and margin information at the current position of the helicopter 11 sequentially transmitted from the reception base station 2, and extracts the extracted helicopter 11. The reception electric field value, the bit error rate, and the margin information representing the reception state at the current position are sequentially stored in the recording medium 36 and output to the display unit 37.
The angle information extraction unit 32 extracts the current angle information of the parabolic antenna 21 transmitted from the parabolic antenna control processing unit 23 of the receiving base station 2 via the data communication processing units 24 and 34, and the parabolic antenna angle calculation processing unit To 35.
The parabolic antenna angle calculation processing unit 35 is based on the current position information of the helicopter 11 input from the GPS information extraction processing unit 33 and the current angle information of the parabolic antenna 21 input from the angle information extraction unit 32. A parabolic antenna control signal 38 for controlling the azimuth and elevation angle or depression angle is generated and transmitted to the parabolic antenna control processing unit 23 via the data communication processing units 31 and 24. Then, the parabolic antenna control processing unit 23 controls the azimuth and elevation angle or depression angle of the parabolic antenna 21 based on the transmitted control signal.

表示部３７は、図２に示すように、ＧＰＳ情報抽出処理部３３、記録媒体３６から入力されるヘリコプタ１１の現在、過去の位置データ(緯度、経度、高度)に基づき、表示部３７の表示画面２０１の平面地図２０２上に、ヘリコプタ飛行軌跡２０３、飛行高度２０５を表示すると共に、受信電界値、ビットエラー率、マージン抽出処理部３４、記録媒体３６から入力されるヘリコプタ１１の夫々の位置における受信電界値、ビットエラー率、マージン情報に基づき、夫々の位置における受信状態２０４を合わせて表示する。
即ち、図２に示すように、表示部３７の表示画面２０１には、表示される平面地図２０２上に、例えば受信電界強度を線の太さで表現したヘリコプタ飛行軌跡２０３と、夫々の飛行軌跡２０３における個々の受信状態を○印の色で表現した受信状態２０４、及び飛行高度２０５が表示される。
このように、パラボラアンテナ２１をヘリコプタ１１の方向に向くようＧＰＳ追尾制御する場合、
（１）ＧＰＳ追尾中に、例えば１秒間隔で取得したヘリコプタ１１の位置データ（緯度、経度、高度）をハードディスクなどの記憶媒体３６に保存する。
（２）（１）のデータに更に受信状態(受信電界値、ビットエラー率、マージン)をデータ化して記憶媒体３６に保存する。
（３）（１）（２）で保存したデータを基に、表示部３７の表示画面上に飛行軌跡と受信状態が目視確認できるように表示する。
ことにより、例えば、特定の基地局に関する最適な飛行経路の事前計画を立てるに際し、表示部３７の表示画面２０１の平面地図２０２上で、最適な飛行経路が目視確認できる。
以上説明したように、本発明によれば、事前に受信状態が悪くなる飛行経路が予測でき、かつ飛行実績を重ねるほど予測精度を高めることができるため、生中継などのパラボラアンテナの方向調整に有効利用できる。 As shown in FIG. 2, the display unit 37 displays the display of the display unit 37 based on the current and past position data (latitude, longitude, altitude) of the helicopter 11 input from the GPS information extraction processing unit 33 and the recording medium 36. The helicopter flight trajectory 203 and the flight altitude 205 are displayed on the plane map 202 of the screen 201, and the received electric field value, the bit error rate, the margin extraction processing unit 34, and the helicopter 11 input from the recording medium 36 at the respective positions. Based on the received electric field value, bit error rate, and margin information, the reception status 204 at each position is displayed together.
That is, as shown in FIG. 2, on the display screen 201 of the display unit 37, for example, a helicopter flight trajectory 203 in which the received electric field strength is expressed by the line thickness on the displayed planar map 202, and the respective flight trajectories. A reception state 204 in which each reception state in 203 is expressed by a color of a circle and a flight altitude 205 are displayed.
In this way, when GPS tracking control is performed so that the parabolic antenna 21 faces the helicopter 11,
(1) During GPS tracking, for example, the position data (latitude, longitude, altitude) of the helicopter 11 acquired at intervals of 1 second is stored in a storage medium 36 such as a hard disk.
(2) The reception state (reception electric field value, bit error rate, margin) is further converted into data and stored in the storage medium 36.
(3) Based on the data stored in (1) and (2), the flight trajectory and the reception state are displayed on the display screen of the display unit 37 so that they can be visually confirmed.
Thus, for example, when making a prior plan of an optimal flight path for a specific base station, the optimal flight path can be visually confirmed on the plane map 202 of the display screen 201 of the display unit 37.
As described above, according to the present invention, it is possible to predict a flight path in which the reception state is deteriorated in advance, and it is possible to increase the prediction accuracy as the flight performance is accumulated. Effective use.
