Description

  The present invention relates to a direction adjusting apparatus for an FPU receiving base station system that receives data wirelessly transmitted from a transmission point and controls a line system that transmits video and audio signals from a base station to a predetermined location.

  As a relay means from outside the station for television broadcasting, an outside relay using an FPU (Field Pick-up Unit) transmitter mounted on a mobile relay vehicle is often used. At the interview site, the antenna of the FPU transmitter mounted on the mobile relay vehicle is directed to the FPU receiving base station (hereinafter simply referred to as “base station”), and the interviewed video is transmitted to the broadcast station via the base station. In general, the base station is installed on a mountaintop with a good view, and can receive radio waves from a circle around it by a rotating antenna.

  In order to realize high-quality data transmission between the base station and the relay point (FPU transmitter), the direction adjustment of the antenna on the FPU transmitter side and the antenna of the base station (hereinafter, also simply referred to as “tone”) Very important.

  The antenna on the base station side is controlled by remote control from the broadcasting station, but in recent years, an apparatus for performing the remote control has become GUI, and the operator can easily control the base station.

As a control device including such a GUI, for example, there is a technique that allows easy confirmation of a radio wave propagation cut-off zone while performing a tone (see, for example, Patent Document 1). According to this technology, the topographic information in the direction in which the rotating parabolic antenna is facing, more specifically, the height and the vertical angle line of the antenna are displayed in a vertical section, so that the operator may be blocked from propagating radio waves. It is possible to easily grasp whether or not there is.

  By the way, remote control of a base station has become very easy due to the progress of GUI conversion as described above. However, problems have arisen with the advance of GUI and the ease of remote control. In other words, it has become easy to reflect the operator's intention through the GUI, but even an erroneous operation or an operation at a timing that should not be operated is immediately reflected and the material such as video and audio data is transmitted during transmission. There is a possibility that the transmission of the material may be interrupted due to a change in the setting of the device related to the transmission.

  The present invention has been made in view of the above situation, and an object thereof is to prevent transmission from being interrupted during transmission of materials such as video and audio data in an FPU receiving base station system. It is to provide a technology that can.

  The device according to the present invention relates to a direction adjusting device. This device is a direction adjusting device of an FPU receiving base station system that transmits data to a predetermined place directly from a transmission point or via a base station by a plurality of line systems, Display control means for displaying a backup line system in which data is not transmitted in a distinguishable manner, and setting protection means for displaying an inquiry as to whether the change operation is valid or invalid when an operation for changing the displayed line system is performed.

And the spare system of the head office 30 is shown with the broken line in the state which is not connected with a specific FPU apparatus. Here, the broken line is shown extending in the horizontal direction.

  FIG. 4 is a flowchart showing processing when the “system” button 102 is pressed. When the operator presses the “system” button 102 to display the system screen display state 105 (S10), the operator subsequently presses the malfunction prevention button 110 (S12). Then, in the system / tone screen display area 113, as shown in FIG. 2, the line system during material transmission is displayed with a bold line, and the spare system is displayed with a broken line (S14).

  While the setting change operation for the device that is transmitting the material is not performed (N in S16), the display that the line system that is transmitting the material is the thick line and the standby system is the broken line is continued (S14).

  Then, when an operation for changing the setting related to the device during material transmission, for example, an operation for changing the material transmission system to the standby system (Y in S16), a warning message window for confirming whether or not to switch to the screen is displayed. 111 is displayed (S18). That is, an inquiry is made as to whether to enable or disable the setting change operation related to the device during material transmission.

  If the operator presses the “No” button in the warning message window 111 and does not approve the setting change (N in S20), it is determined that the setting is not changed, the state where the setting cannot be changed is continued, and the warning message window 111 disappears. The display in which the line system during material transmission is indicated by a thick line and the spare system is indicated by a broken line continues (S16). When the operator presses the “Yes” button in the warning message window 111 and approves the setting change (Y in S20), the device setting can be changed (S22).
