Example 1
Fig. 1 is the block diagram of the vehicle-mounted receiver apparatus of the invention process form 1.Among Fig. 1, FM antenna 1 receives the electric wave of FM broadcasting.Receiving circuit 2 extracts the high-frequency signal of assigned frequency from the electric wave that antenna 1 receives, utilize internal circuits such as high-frequency amplifier circuit, mixting circuit, intermediate frequency amplifier circuit, detecting circuit to implement the signal processing of regulation, and the output low frequency voice signal.Amplifying circuit 3 will be amplified and be offered loud speaker 4 by the voice signal of receiving circuit 2 outputs makes its sounding.Microcomputer (means, display control means are set in electric field strength detection means, broadcasting station) 5 is according to the electric field intensity signal (so-called " S rice signal " of the detecting circuit output of receiving circuit 2; S meter signal) fs detects electric field strength, and the channel control signal cc that will specify the frequency that extracts to use simultaneously is input to receiving circuit 2.And, in microcomputer 5, be provided with electric field intensity signal fs be converted to digital signal AD converter, storage control program ROM and as the RAM of working region.At the memory that is used for presetting (storage means) 6, storing area-name, zone name, broadcasting station names etc. such as Dou Daofu county in advance.Its details will be narrated in the back.Key operation portion (input medium) 7 adjusted key, numerical key, enter key (enter key) etc. by power turn-on/scission of link, volume and formed.To order or data input microcomputer 5 according to operation.Display part (demonstration means) 8 will be presented on the picture by the video data of microcomputer 5 inputs.
Fig. 2 illustrates the content that relates to the broadcasting station that is stored in the part zone (Kyoto Prefecture, Osaka, Bingku county) in the memory 6 and utilizes microcomputer 5 to detect and be stored in the electric field strength data of RAM.Among Fig. 2, will be stored as area code " 1 ", " 2 ", " 3 " of the regional identifying information of cog region domain name Kyoto Prefecture, Osaka, Bingku county in advance.Again, corresponding location is a plurality of subregions with each Region Segmentation, and the broadcasting station name and the frequency of each subregion are stored.For example, in mansion, the capital of a country of area code " 1 " (Kyoto) scope, the location is in the subregion in Tianjin, palace Kyoto 1 and Kyoto 2 to be arranged, and to store FM capital of a country platform and the frequency that frequency is 79.8MHz respectively be the NHK-FM platform of 86.1MHz.
And the content stores that will be referred to the radio station in all Dou Dao mansion counties and districts territories from Hokkaido to Okinawa in fact in advance is in memory 6.
Also have,, also information of place names etc. can be used as area code though regional identifying information is expressed as area code.
Below action is described.
Fig. 3 is the flow chart of expression by the reception control action of the microcomputer execution of Fig. 1.Utilize the operation critical region code of key operation portion 7 whether to be transfused to (step ST1), under the situation that area code is transfused to, begin to carry out tuning (step ST2).For example, when the position in Tianjin, palace input area code " 1 ", the frequency of all subregions (Kyoto 1～Kyoto 5) under the Kyoto Prefecture zone in the readout memory 6 is input to receiving circuit 2 with the channel control signal cc that extracts each frequency successively.Then, detect the electric field strength in each subregion of detecting circuit output and being stored in the RAM.Judge and whether can judge electric field strength subregion (step ST3) under the broadcasting station of (for example, more than " 5 ") more than setting therein.
Under the situation of the subregion under the broadcasting station that can judge the electric field strength more than the setting, finish tuning (step ST4).On the other hand, under the situation in the broadcasting station that can't judge the electric field strength more than the setting, finish this flow process (flow chart).In the example shown in Figure 2, Kyoto 1, FM capital of a country, electric field strength " 10 "; Kyoto 1, NHK-FM, electric field strength " 10 "; Kyoto 2, FM capital of a country, electric field strength " 5 "; Kyoto 2, NHK-FM, electric field strength " 5 ", Kyoto 5, FM capital of a country, electric field strength " 6 "; Kyoto 5, NHK-FM, electric field strength " 6 " is judged as the broadcasting station with the above electric field strength of setting.
Then, carry out the exhalation (step 5) in broadcasting station.Promptly specify 1 broadcasting station the broadcasting station of the electric field strength more than setting.In this case, the broadcasting station of the electric field strength more than setting, the broadcasting station of exhalation maximum field intensity.Then, the broadcasting station of breathing out is set in the memory 6 that presets usefulness (step ST6), finishes this flow process then.Whether adopt any designation method, can predesignate with control program, also can be according to the operating provision of key operation 7.
And the subregion determination processing of step ST3 is not preferably under the situation of key operation portion 7 input area codes, and also each is fixed time and carries out several continuously.In addition, preferably adopt every mistake to carry out continuously 5 times in 1 minute, obtain the method that the mean value of electric field strength is judged.
As mentioned above, if adopt this example 1, then selected to have the key operation portion 7 of the area code by operation input identified region and the electric field strength that belongs to by the electric wave in the broadcasting station in the zone of the area code of key operation portion 7 inputs has been detected, the structure of the microcomputer 5 in the broadcasting station of the electric field strength that the setting setting is above, even therefore have under the situation that can't receive the GPS electric wave, also can receive the effect of broadcasting with optimum state.
In this case, the frequency of a plurality of subregions that microcomputer 5 will be become by the Region Segmentation of the area code of key operation portion 7 input is read from memory 6, detection belongs to the electric field strength of electric wave in the broadcasting station of each subregion, therefore, has the effect of electric field strength that can each subregion of high speed detection.
Again, in this case, set the broadcasting station of maximum field intensity the broadcasting station of the electric field strength of microcomputer 5 more than detecting setting, therefore have the effect that can receive broadcasting with the best and stable status.
Example 2
The structure of the receiving system in the example 2 is identical with the structure of example shown in Figure 11, and is just different in the processing of setting the broadcasting station.In the example 2, the broadcasting station that microcomputer 5 will have the above electric field strength of setting is presented in the display part 8, from the broadcasting station of this demonstration, sets the broadcasting station that utilizes key operation portion 7 to select.
As mentioned above, adopt this example 2, the broadcasting station of the above electric field strength of setting is shown in display part 8, and the specified broadcasting station of selection by the 7 set basis users of key operation portion, therefore when the user wants to hear desirable specific broadcasting, produces effect.
Example 3
The structure of the receiving system in the example 3 is identical with the structure of example 1 and example 2, and is just different in the processing of setting the broadcasting station.In the example 3, microcomputer 5 becomes than setting under the little situation in the electric field strength of the electric wave in the broadcasting station of having set, in different subregions, detect the electric field strength of the electric wave in identical broadcasts radio station, electric field strength at the electric wave in detected identical broadcasting station is under the situation of (for example more than 5) more than the setting, resets this identical broadcasting station.
Again, vehicular seat is for the dance crane, when being subregion Kyoto 5, is set at the have electric field strength FM capital of a country platform of frequency 87.2MHz of " 10 ".Thereafter, when vehicle moved to the capital of a country of subregion Kyoto 3, the electric field strength of the FM capital of a country platform of frequency 87.2MHz was reduced to " 2 ".At this moment, the electric field strength of the electric wave in detected identical broadcasting station is less than setting (for example, less than 5), therefore, again the FM capital of a country platform of the 89.4MHz of frequency with electric field strength " 10 " set.
As mentioned above, if adopt this example 3, become than setting under the little situation in the electric field strength of the electric wave in the broadcasting station of having set, in different subregions, the situation of electric field strength more than setting detected in the identical broadcasts radio station, and this identical broadcasting station is set again, therefore, even under the situation that the broadcasting wave of listening to dies down because of vehicle moves, also only need set again and just can continue to listen to identical broadcasts frequency.
Example 4
The structure of the receiving system in the example 4 is identical with the structure of example 1～3, and is just different in the processing of setting the broadcasting station.In the example 4, even begin tuning and the electric field strength of the electric wave in the broadcasting station that belongs to each subregion detected under the situation in the broadcasting station that also can't detect the above electric field strength of setting at microcomputer, will " not search the good broadcasting of electric wave " etc. such can't detected information, promptly, the information of not measuring is presented on the display part 8.
For example, when the current location of vehicle was Osaka of division code " 2 " Osaka, the user was by key operation portion 7 input division codes " 1 ".At this moment, as shown in Figure 2, all be " 1 " as the electric field strength of the Kyoto1～Kyoto 5 of the subregion of division code " 1 ", littler than setting " 5 ".At this moment, in the flow chart of Fig. 3, can't from the Infinite Cyclic of carrying out step ST2 and step ST3 repeatedly, break away from.For fear of this state, will expression because the division code of input causes the information of not measuring of the meaning that electric wave can't receive to be presented on the display part 8, to urge the user area code is changed.
As mentioned above, adopt this example 4, because when in the regional extent of appointment, not detecting the broadcasting station of the electric field strength more than the setting, therefore the nd meaning is shown on the display part 8, plays the effect that can not notify wrong input in the zone of the zone of the area code of user's mistake input and current location simultaneously.
Example 5
The structure of the receiving system in the example 5 is identical with example 1～4 structure, and is just different in the processing of setting the broadcasting station.In the example 5, even begin tuning and the electric field strength of the electric wave in the broadcasting station that belongs to each subregion is detected under the situation in the broadcasting station that also can't detect the above electric field strength of setting at microcomputer, the area-name that will " not search the good broadcasting of electric wave " etc. such can't detected information, promptly do not measure under the broadcasting station of the electric field strength of information more than setting is presented on the display part 8.
For example, when the current location of vehicle was Osaka of division code " 2 " Osaka, the user was by key operation portion 7 input division codes " 1 ".At this moment, as shown in Figure 2, all be " 1 " as the electric field strength of the Kyoto1～Kyoto 5 of the subregion of division code " 1 ", littler than setting " 5 ".At this moment, will expression because the division code of input causes the information of not measuring of the meaning that electric wave can't receive to be presented on the display part 8, show Osaka simultaneously as the area-name of the area code " 2 " under the big FM802 of electric field strength, FM Osaka, these broadcasting stations of NHK-FM.
As mentioned above, if adopt this example 5, in the time can't detecting the broadcasting station of the electric field strength more than the setting, with expression can't the detected meaning the broadcasting station of the electric field strength of the information of not measuring more than setting under area-name show, therefore play not simultaneously, can inform the area-name of reception good to the user in the zone of the zone of the area code of user's mistake input and current location.
Example 6
Fig. 4 is the block diagram of the structure of the receiving system in the expression example 6.Among Fig. 4, antenna 9 receives the GPS electric wave of determining current location.GPS receiving circuit (GPS receives means) 10 detects the GPS electric wave of being imported by antenna 9, and converts the current location information of digital signal to, to microcomputer 5 outputs.Other inscapes are identical with inscape shown in Figure 1, therefore omit its explanation.
Below action is described.
Microcomputer 5 is differentiated and is utilized GPS receiving circuit 10 whether can determine current location, in the time can determining current location, detects the electric field strength of electric wave in the broadcasting station in the zone that belongs to this current location.On the other hand, in the time can't determining current location according to GPS receiving circuit 10, microcomputer 5 will impel the information of area code input to be shown in display part 8, detect the broadcasting station of the electric field strength more than the setting in the regional extent of the area code of importing.
As mentioned above, if adopt this example 6, in receiving system with the GPS receiving circuit 10 that receives the GPS electric wave and obtain current location, in the time can determining current location according to GPS receiving circuit 10, electric field strength to the electric wave in the broadcasting station under the zone of the current location determined detects, in the time can't determining current location, the electric wave by the electric field strength in the broadcasting station under the zone of the area code of key operation portion 7 input is detected, therefore, even utilizing the GPS receiving circuit can't determine under the situation of current location, also can receive broadcasting with optimum state.
As mentioned above, adopt the present invention, receiving system adopts the input medium with the regional identifying information that will use corresponding to operation input identified region, the electric field strength detection means that the electric field strength that belongs to by the electric wave in the broadcasting station in the zone of the regional identifying information of input medium input is detected, and the electric field strength that is set in the detected electric wave of electric field strength detection means is set the structure of means above the broadcasting station in the broadcasting station of setting, therefore, even under the situation that can't receive the GPS electric wave, also has the effect that can receive broadcasting with optimum state.
