Abstract

PURPOSE:To direct a reception antenna to a mobile relay car automatically at a relay start time from the mobile relay car by registering a relay start time and a setting angle data of the reception antenna at that point into a memory in advance. CONSTITUTION:A preset control section 9 reads all preset information and time information in a district name data setting section 11 and a time preset storage section 13 and stores them into a data memory 8. Then time information and a district name in the preset information are read from the memory 8. Then a date and time is read from a calendar clock section 14 and whether or not the extracted time information and the readout date and time are coincident is decided. When they are coincident, a setting angle to the extracted district name is extracted from the memory 8 and supplied to a control terminal station 6. The control terminal station 6 sends the setting angle data to a controlled terminal station 5 through a control circuit 104. The controlled terminal station 5 sets an angle of an FPU reception antenna 3 according to the setting angle data. The antenna 3 is set in this way and a microwave from the FPU transmission antenna 1 of a mobile relay car 2 is received.

Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to an FPU (field pickup) that receives microwaves from an FPU (field pickup) device mounted on a mobile relay vehicle.
The present invention relates to a remote control method for a receiving antenna in which the receiving antenna of a receiving base station is set in the direction of a mobile relay vehicle.

(Prior Art) Since the receiving antenna of an FPU receiving station generally has directionality, it is necessary to control the receiving antenna so that it points in the direction in which the mobile relay vehicle is located. This control has conventionally been performed as follows.

That is, when the mobile relay vehicle arrives at a predetermined position and starts relaying, the operator inputs setting angle (horizontal and vertical angle) data for the position of the mobile relay vehicle into the reception antenna setting device. Then, the receiving antenna setting device sets the horizontal and vertical angles of the receiving antenna based on this setting angle data.

Such operations are performed every time a relay is performed.

(Problems to be Solved by the Invention) As mentioned above, in the conventional receiving antenna control method, although the relay point is known in advance, the operator manually controls the receiving antenna at the relay time. The setting angle data of the antenna is instructed to the receiving antenna setting device.Therefore, the operability and operability were poor.

The present invention has been made in view of the above circumstances, and its purpose is to provide a receiving antenna control method that automatically directs the receiving antenna toward the mobile relay vehicle at the time when broadcasting from the mobile relay vehicle starts. It is in.

(Means for Solving the Problems) In order to achieve the above object, the receiving antenna control method of the present invention is implemented from an FPU device mounted on a mobile relay vehicle and transmitting microwave video signals and audio signals using a transmitting antenna. A receiving antenna control method comprising: a receiving antenna setting device that sets a receiving antenna for receiving the microwave at a setting angle specified by an operator and directs the receiving antenna in a direction in which the mobile relay vehicle is located; A place name data setting storage means for storing setting angle data corresponding to a place name; a time preset storage means for storing time information corresponding to the setting angle data; a clock means for measuring time and indicating a time; and the time preset storage means. It is determined whether the time information stored in the time information and the time indicated by the time measurement means are the same, and if they are the same, the setting angle stored in the place name data setting storage means corresponding to the time information is determined. The receiving antenna control device includes a preset control means for applying data to the receiving antenna setting device.

(Example) Next, an example of the present invention will be described in detail with reference to the drawings.

It consists of

FIG. 2 is a flowchart showing a processing example of the embodiment of FIG.

The operation of the embodiment of the present invention will be explained below using each country.

First, the operator enters preset information including a place name (the name of the place where the mobile relay vehicle 2 is parked) and the setting angle data of the FPU receiving antenna 3 for this place name, as well as the setting angle in this preset information, from a keyboard (not shown). Enter the time information for setting the FPU receiving antenna 3 in the data.

Then, the keyboard input section 10 inputs this preset information and time information and passes it to the data processing section 7.
The data processing section 7 stores preset information in the place name data setting storage section 11 and time information in the time preset storage section 13, respectively. Such processing is performed for scheduled relay points and times.

Next, the preset control section 9 of the data processing section 7 reads out all the preset information and time information stored in the place name data setting storage section 11 and the time preset storage section 13 and stores them in the data memory 8. Then, one piece of time information and a place name in the preset information are read out from the data memory 8 (step 51 in FIG. 2).Next, the date and time is read out from the calendar clock section 14 (step S2).
, Determine whether or not the retrieved time information and the read date and time match (step S3). If they do not match, return to step S2 and repeat the processing of steps S2 and S3.0 Conversely, if they match, skip When YES in step S3), the set angle data for the retrieved place name is retrieved from the data memory 8 (step S4), and this set angle data is passed to the control terminal station 6. The set angle data is sent to the controlled terminal station 5 (step S5), and the controlled terminal station 5 sets the angle (horizontal and vertical angle) of the FPU receiving antenna 3 according to this set angle data (along with step S6, the controlled terminal station 5 also sends the set angle data to the controlled terminal station 5). is reported to the control terminal station 6 through the monitoring line 105.The FPU receiving antenna 3 is thus set, and the FP of the mobile relay vehicle 2 is
The micro signal sent from the U transmitting antenna 1 is received.

Then, the received microwave is sent to the FPU receiver 4 and the preset controller 9 determines whether or not time information is still stored in the data memory 8 (step S7).
), if time information is still stored, step S
Return to step 1 and repeat the operations described above. If the data is not stored in the data memory 8, the process ends.

Furthermore, the place name data readout and display section 12 can display information stored in the place name data setting storage section 11 and the time preset storage section 13.

Note that in this embodiment, the controlled terminal station 5 and the control terminal station 6
Although the controlled terminal station 5 and the control terminal station 6 are connected by a line, it goes without saying that the controlled terminal station 5 and the control terminal station 6 may be integrated.

(Effects of the Invention) As explained above, in the receiving antenna control method of the present invention, the relay start time and the setting angle data of the receiving antenna at that point are registered in advance in the memory, and when the relay start time comes, the receiving antenna control method automatically Direct the receiving antenna toward the relay point.
Therefore, in FPU relay operations where there are many relay points and a schedule is established during planning, operability and
Operability can be improved.
