Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a global positioning system [Global Positioning] installed on a moving body.
System (hereinafter, simply referred to as "GPS")] The present invention relates to a broadcasting station automatic channel selection receiving device for receiving broadcasting from a satellite.

[0002]

2. Description of the Related Art As a conventional example, a broadcast receiving device such as a radio or a television is mounted on a moving body such as an automobile or a ship, and the frequency to be received is selected and set by an artificial operation. Then, in these broadcast receiving devices, a plurality of channels are set so that they can be easily selected,
A device capable of selecting a channel with one button operation is mainly used.

[0003]

However, the above-mentioned conventional automatic broadcasting station receiver for broadcasting station is premised on being fixedly used, and for example, the receiving apparatus is selected after setting the broadcasting station to be received. If the mounted mobile unit moves, the broadcasting of the selected broadcasting station becomes remote in many cases and cannot be received. In that case, it is necessary to set the broadcasting of the broadcasting station that can be received again. That is,
When the frequencies assigned to each channel are moved and the radio wave propagation is significantly attenuated in this frequency band and reception becomes impossible, it is necessary to reset the frequency manually. Further, it has been necessary to artificially operate the directional antenna used in ships or the like toward the broadcasting station.

As described above, the broadcast receiving device mounted on the mobile body has a function of receiving various broadcasts, but the broadcast station to be received changes depending on the movement, and the person receiving the broadcast changes each time. It was necessary to select the channel by the operation described above, and the stored channel selection function had to be reset to facilitate the operation.

Here, the present invention automates these artificial operations, and the tuning is always automatically performed by automatically selecting the optimum broadcasting station for the present position from the broadcasting station information stored in advance and the GPS receiving section. The purpose of the present invention is to provide a broadcasting station automatic tuning receiver that can tune a channel and, when using a directional antenna, automatically directs the directional antenna in the radio wave emission direction of the selected broadcasting station. To do.

[0006]

In order to achieve the above object, the present invention is directed to a broadcasting station automatic channel selection receiving apparatus installed in a mobile body, which receives broadcasting from a GPS satellite and mainly moves to the current position or progress. The means for extracting the data necessary for each process represented by the direction and outputting as an electric signal, and the position and transmission frequency of each broadcasting station that covers the moving range of the moving body that is stored in advance from the obtained current position and other Means for giving information to the channel selection section, means for automatically setting the channel according to the information of the selected broadcasting station to receive this channel, means for displaying the setting state of the receiving channel, and receiving direction And a means for directing a selective antenna to a selected broadcasting station.

[0007]

According to the present invention, with the circuit configuration described above, the GPS receiver decodes information from GPS satellites and outputs the current position and traveling direction to the automatic channel selection processing section as electric signals. -ROM [Compact Disc-Read On
information such as the position of the broadcasting station or the transmission frequency is supplied to the automatic channel selection processing unit, and the automatic channel selection processing unit processes and receives this information. The broadcasting station is determined, its channel is set, the antenna is directed in the direction of the broadcasting station of the channel to receive, and the channel and broadcasting station information set for reception are displayed and shown to the user.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing a circuit configuration in an embodiment of the present invention. In FIG. 1, a broadcasting station automatic channel selection receiving device according to the present invention includes a GPS receiving unit 1, a broadcasting station information storage medium 2, an automatic channel selection processing unit 3, a setting status display unit 4, a channel selection 5 Unit, 6 antenna rotating mechanism, 7 broadcast receiving unit, 8 broadcast receiving antenna. The arrows attached to the lines connecting the blocks indicate the directions of signal transmission / reception.

GPS by transmitting and receiving GPS radio waves with GPS satellites
On the other hand, the information obtained by the receiving unit 1 includes the current position information of this mobile unit. This current position information is, for example, the CPU
Outputs to the automatic channel selection processing unit 3 having [Central processing unit] as a main control member. The automatic channel selection processing unit 3 reads out necessary broadcast station information from the input current position information from the broadcast station information storage medium 2, and the information set in the channel selection unit 5 is set to an unsuitable state such as an unreceivable state. When
Update the information of the unused channel with priority. The channel setting information is output to the setting state display unit 4 to display and show the channel setting state to the user.

On the other hand, there is information on the traveling direction of the moving body. The information on the traveling direction is processed by the GPS receiving unit 1 and then output to the automatic channel selection processing unit 3, and the automatic channel selection processing unit 3
Then, the direction of the broadcasting station is determined from the position of the broadcasting station, the current position and the moving direction obtained by the GPS receiving section 1 according to the currently selected channel information, and the directional antenna is directed to the antenna rotating mechanism 6 in the broadcasting station direction. To output the signal. The antenna rotation mechanism 6 rotates the antenna according to the signal input from the automatic channel selection processing unit 3.

By the way, when the current position information of the moving body on the one hand and the traveling direction information of the moving body on the other hand conflict,
Channel selection is determined based on the priority order in the broadcast station information storage medium 2 stored in advance.

If information about the traveling direction cannot be obtained, such as when the moving body is stopped, a device such as a direction sensor may be used supplementarily.

Additionally, the channel selection section 5 additionally has a channel selection button for the user to select a channel, and the user can arbitrarily select a broadcasting station by operating the one button of the channel selection button. It is also possible to output the information of the artificially selected channel to the broadcast receiving unit 7,
In addition, the broadcast receiving section 7 rotates the broadcast receiving antenna 8 via the antenna rotating mechanism 6 based on the information of the selection button, and creates a good reception state with a large antenna gain.

[0015]

As described above, according to the present invention, in selecting a broadcast receiving apparatus mounted on a mobile body, even if the selectable broadcast station changes due to movement, the optimum receiving state is selected by the automatic machine. Or, if necessary, by operating the channel button, any channel can be obtained in good condition, and the channel selection from each broadcasting station is automatically and optimally updated. be able to.
