Abstract

PURPOSE:To prevent a storage content of a 2nd storage means corresponding to a preset button from being mismatched with the selection content of a district selection means by reading frequency information receptible at a prescribed district from a 1st storage means and writing it in a 2nd storage means with the prescribed operation of a district selection means. CONSTITUTION:When a district selection button in an operation means 11 is depressed and an automatic memory button is depressed, a control means 16 transfers frequency information of a broadcast station expected of excellent reception at an area designated from a ROM 17 to a preset area of a RAm 18 in the lump and written therein. Then the frequency written in a 1st channel of the preset area is read to control a PLL circuit 9 and the frequency is tuned and the said frequency is inputted to the ROM 17 to read a relevant broadcast name and the frequency and the broadcast station name are outputted to a display means 10.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a radio equipped with a broadcasting station name notification function that identifies a received broadcasting station based on regional information and received frequency information and announces the name of the broadcasting station. Regarding the receiver.

[Prior Art] A radio receiver is known that is equipped with a broadcasting station name notification function and is suitable for being mounted on a vehicle or the like that travels over long distances. FIG. 5 is a circuit block diagram of such a radio receiver, in which 1 is a high frequency amplifier, 2 is a mixer, 3 is an intermediate frequency amplifier, 4 is a detector, 5 is a low frequency amplifier, 6 is a control means, and 7 is a Read-only storage means (hereinafter referred to as ROM). 8 is a read/write storage means (hereinafter referred to as RAM). 9 is a PLL circuit, 10 is a display means, and 11 is an operation means. The control means 6 receives a field strength signal, a broadcasting station detection signal, etc. from the intermediate frequency amplifier 3, and receives an operation signal from the operation means 1l, and operates a PLL circuit 9.
, ROM7, RAM8, and display means IO. R.O.
M7 records information regarding the names of broadcasting stations from which good reception of a predetermined electric field strength or higher can be expected for each region and the frequencies corresponding to each. The RAM 8 is provided with a plurality of readable/writable preset areas corresponding to the plurality of preset buttons in the operating means 1'1, and information regarding frequencies is recorded in each area.

FIG. 6 is a flowchart showing the broadcasting station name announcement operation of the control means 6. When the intermediate frequency amplifier 3 inputs a signal indicating that a broadcasting station with a predetermined electric field strength or higher is received to the control means 6 (step 20), the control means 6 inputs the tuned frequency signal to the ROM 7 and updates the stored contents of the ROM 7. (Step 21). At this time, if a region selection signal is input from the operating means l1 (step 22), the control means 6 reads from the ROM 7 the name of a broadcasting station corresponding to the above-mentioned tuned frequency that can be received in the selected region, and selects the tuned frequency and broadcast. The station name is displayed on the display means 10 (step 23). If the area selection signal is not input in step 22, the control means 6 displays only the tuned frequency on the display means 10. In addition,
There is also known a radio receiver that uses an audio synchronization device to announce the name of a broadcasting station audibly instead of visually displaying it using the display means 10.

[Problems with the prior art] In the prior art as described above, the recorded contents of the ROM7 and the RA
It had no relation to the contents of M8's records.

Therefore, if broadcast stations that can be received in a certain area are preset in the RAM 8, if the vehicle enters another area, most of the preset stations will become unreceivable, and the preset contents will become meaningless information. Additionally, there is a known function (so-called auto memory) that automatically presets only those stations that can be received well at a certain point in RAM8 with a single operation, but this function is also not linked to the region selection function, so If it is not updated after selection, there is a problem in that the tuned frequency is checked against information on stations that can be received in the previously selected area, resulting in incorrect notifications.

[Means for Solving the Problems] In order to solve the above problems, the present invention provides: a first storage means in which names of broadcasting stations receivable for each region and frequency information corresponding to the broadcasting stations are written; , a second storage means that can arbitrarily read/write a plurality of frequency information by a predetermined operation of the operating means; a region selection means and a receiving circuit; and an announcement of a broadcasting station name selected based on the region information and received frequency information. The system includes a notification means, and a control means for writing frequency information receivable in a predetermined area stored in the first storage means into the second storage means by a predetermined operation of the region selection means. [Operation] When the control means detects a predetermined operation of the area selection means, information on frequencies receivable in the specified area is read from the first storage means and written into the second storage means. [Embodiments] Embodiments of the present invention will be described below based on the drawings, and the same components as those in the prior art are given the same reference numerals, and detailed explanations will be omitted.

FIG. 1 is a block diagram showing the structure of the apparatus of the present invention, which differs from the prior art in that it has a structure in which recorded information can be transferred from the ROM 17 to the RAM 18 by commands from the control means 16.

Next, the operation will be explained.

FIG. 4 is a flowchart illustrating an example of region designation input operation in the embodiment described below.

When the region selection button within the operating means 1 is pressed (step 48), the control means 16 operates a built-in timer (step 49). The control means 16 checks whether the timer has not counted 5 seconds (step 50), and if it has not counted yet, checks whether the auto memory button in the operating means 11 has been pressed (step 51), and if it has not been pressed. If so, return to step 50. If the auto memory button is turned on here, it is assumed that the region designation input has been completed, and a preset operation to be described later is performed (step 52).

If it is detected in step 50 that the timer has counted 5 seconds, the control means ↓6 checks whether the auto memory button has been pressed (step 53), and if it has been pressed, performs the normal auto memory operation (step 54). ).

The above is just an example, and various methods can be used, such as pressing the same region selection button twice or pressing other buttons in succession. However, when the present invention is implemented, the auto-memory function becomes substantially unnecessary, so when the present invention is implemented in a product that is already equipped with an auto-memory button, it is preferable to use the auto-memory button.

FIG. 2 is a flowchart showing a first embodiment of the present invention.

When the control means 16 detects the region designation input as illustrated in FIG. 4 (step 25), the control means 16
7, the frequency information of broadcasting stations that can be expected to receive good reception in the specified area is transferred all at once to the preset area of the RAM 18. Write (step 26). Then read the frequency written in the first channel of the preset area. The PLL circuit 9 is controlled to tune to the frequency (step 27), the frequency is input to the ROM 17, the name of the corresponding broadcasting station is read out, and the frequency and the name of the broadcasting station are output to the display means 10 (step 28). .

Here, when the reset button corresponding to another channel is pressed (step 29), the control means 16
The frequency information is read from the corresponding preset area of No. 8, and tuned to the frequency using the same control as above (step 30), and the name of the broadcasting station corresponding to the frequency is set to R.
The information is read from the OM 17 and displayed on the display means 10 (step 31). If preset button suppression is not detected in step 29, other tuning operations (manual tuning,
(step 32), and if so, the newly tuned frequency is stored in the ROM.
17 (step 33), reads out the name of the broadcasting station corresponding to the frequency that can be received in the area, and displays it on the display means 1.
Display at 0. Frequency information is also input to the RAM 18, and if there is a corresponding preset record, the preset number is also displayed.

By the above operation, just by specifying a region, broadcast stations that can be well received in that region are automatically transferred to the preset area of RAM 18, so the problem of not being able to receive the corresponding broadcast station when receiving presets is resolved. ．． In addition, since the built-in information is used to perform batch presetting, the auto memory function that was previously available can be removed. FIG. 3 is a flow chart showing a second embodiment of the present invention. This embodiment is a measure for cases where a large number of broadcast stations are concentrated in areas such as Tokyo, and the number of receivable stations exceeds the number of preset stations. When a region designation input is detected (step 35), the control means 16 stores the number S of broadcast stations that can be received in the region and the RAM 18.
(Step 3)
6). If M is greater than or equal to S and there are more preset areas than stations that can be received in the area (step 37)
As in the first embodiment, the control means 16 reads frequency information that can be received in the area from the ROM 17 and stores it in the RAM.
18 (step 38), tunes to the frequency written in the first channel of the preset area (step 39), reads the broadcasting station name corresponding to the frequency from the ROM 17, and displays it on the display means 10 (step 40).
.

If S is larger than M in step 37 and the number of receivable stations is larger than the number of presettable stations, the control means 16
17, frequency information that can be received in the area is written in the preset area (step 41), and tuning control is performed to the receivable stations that were not preset (step 42), and the name of the broadcasting station corresponding to the received station is read out from the ROM 17. It is displayed on the display means 10 (step 43). If a channel selection button other than the preset button is pressed here (step 44), the control means 16 checks the ROM 17 and RAM 18 to see if there is a station that can be received and for which the preset memory has not yet been tuned (step 45). If so, the selected station is ignored and tuned to that station (step 4G).

If there is no station that meets the above conditions in step 45, the selected tuning operation is controlled (step 47).

With the above operation, you can preset all the broadcast stations that can be received in that area in the RAM 18 by simply specifying the area, and if there is a station that can be received but has not been preset, press any channel selection button. As a result, the unselected stations can be sequentially called, so the user can listen to all receivable stations. Also, presetting of stations that have not been preset can be done arbitrarily as in a normal receiver. Furthermore, when the scan mode is selected in step 44, it is also possible to automatically sequentially tune only the stations that have not been preset. With this configuration, it is very convenient because all receivable stations can be preset and automatically tuned by just two operations: region designation input and scan input.

It should be noted that simply displaying or audibly announcing the existence of the stations that were not preset in step 42 can have some effect.

[Effects of the Invention] As explained above, according to the present invention, frequency information receivable in a predetermined area is read out from the first storage means and written into the second storage means by a predetermined operation of the region selection means, so that the preset Only broadcast stations that can be reliably received in a predetermined area are written into the second storage means without causing any inconsistency between the storage contents of the second storage means corresponding to the buttons and the selection contents of the area selection means. Therefore, it is possible to solve problems such as preset contents being receivable only in other areas and not being able to be received well even if a tuning operation is performed, or the broadcasting station name being unable to be announced.
