Fig. 6 represents the preferred embodiment according to regional information receiver of the present invention, and it can receive regional information when the user moves.It comprises: keyboard 160 receives user's input; The variable filter amplifier 80 of radio frequency, filtering and amplification belong to the high-frequency signal of assigned frequency band and change frequency band the high-frequency signal that is received from radio-frequency antenna 7; Demodulator 90 is demodulated to former data-signal with the signal after amplifying; Decoder 100 is from extracting and the corresponding data of regional information the demodulated digital signal; Global positioning system (GPS) 140 is utilized the coordinate data calculating current location value that receives from low-orbit satellite, for example latitude, longitude and height; Battery 120 provides power supply for the regional information receiver; Memory 150, the storage regional information; Read-only memory (ROM) 151, corresponding area code of locator data that storage is calculated with GPS 140 and the frequency band values relevant with this area's sign indicating number; Controller 110, the regional identity code in the data is extracted in identification, receive regional information when only the current location of being calculated as its area code and GPS 140 is consistent, whether relate to the user according to the regional information that is received then and deposit regional information in different memory space to the set designated area of receiver; Switch 130 is disconnected to the power line of controller 110; Character signal transducer 180 converts the regional information that is stored in the memory 150 by controller 110 data presented on LCD to; LCD display 190 shows the data after changing; With timer 170, preserve the current time.
In the preferred embodiment according to regional information receiver of the present invention of configuration as mentioned above, battery 120 provides power supply by power line for the regional information receiver, yet, if switch 130 keeps disconnecting, power supply is not provided for the variable filter amplifier 80 of radio frequency, demodulator 90, decoder 100 and GPS 140.In this state, the user is by being provided with service time with reference to the guiding book about current area that provides tissue to publish by somewhere information in controller 140.For example, if the regional information generator every two hours provides one minute regional information (mornings nine point, the mornings 11 point, afternoon a bit etc.) from 9 in the morning, then be provided with and comprise point in the mornings nine time started, the data of two hours seeervice cycles and one minute service time.
The corresponding area code in user-selected designated area is set to controller 110 by keyboard 160 with the data about service time, and this designated area for example is user's residence.
After finishing this setting, controller 110 constantly reads the current time from timer 170, and whether the check regional information is available, that is, whether the current time is at 9 o'clock in morning or a little in advance 8: 59 morning for example service time started for example service time started.If satisfy condition, controller 110 is opened switch 130 and is started the variable filter amplifier 80 of radio frequency, demodulator 90, decoder 100 and GPS 140, causes to receive the required subsequent operation of regional information.Hereinafter will be described in more detail.
At first, when beginning to power by power line, the coordinate data that GPS 140 uses four satellites from 24 low-orbit satellites to receive utilizes the trigonometry principle to calculate the absolute position value of its position when receiver user moves, and the positional value that is calculated is sent to controller 110.Controller 110 is sought in ROM 151 and is comprised after the geographic coverage of this position then, extracts the corresponding area code in user position.Extracting suitable frequency band values then is used for receiving regional information from ROM 151.Thereby the frequency band values of being extracted is and the frequency band values of distributing to the area code corresponding area of being discerned.
Use the frequency band values of being extracted, controller 110 changes the tuning frequency band of the variable filter amplifier 80 of radio frequency so that the high-frequency signal that comprises regional information tuning and that amplification is about to be sent out.
When sending in the information service time when comprising the high-frequency signal of regional information, the variable filter amplifier 80 of radio frequency is the filtering and the radio signal of amplifying selected frequency band from the radiofrequency signal that antenna 7 is received, and the signal after will amplifying is exported to demodulator 90.The original digital signal that is demodulated from the high frequency band radio signal by demodulator 90 is provided to decoder 100.These digital signals of decoder 100 decoding are extracted the regional information that removes the additional data that is used for their synchronous and error correction, and the regional information that is extracted is sent to controller 110.
In general, specifying a frequency band for several adjoining areas specifies a frequency band more economical than giving each area.In this case, after the assigned frequency band by current area received regional information, whether the regional identity code in the controller 110 check received data was identical with the area code that GPS 140 is discerned.If two yards identical, further whether the check area code that GPS discerned is consistent with the corresponding area sign indicating number of designated area by controller 110, for example when the user is set to " Seoul " (Seoul) in " fixing area " by keyboard 160.If two yards identical once more, the regional information that is received is deposited in only is the memory space that regional information distributed about fixing area, otherwise it is deposited in another memory space that separates with fixing regional used memory space.Therefore, when this separation storage moves freely the user in the area except that the designated area, can do not lose stored about the information state of particular locality under reception about the lastest imformation in each on-fixed area.
And, when the user returns the designated area, can at any time extract the regional information of having been lost or having forgotten by the user.
In a single day no matter when the user asks, or finish storage, and the regional information of being stored can extract and offer character generator 180 from memory 150.This area's information converts the signal that is used for LCD display 190 to by character signal transducer 180, and the form of the sentence of being made up of with character the user is watched then.
In case the current time exceeds service time, 9: 1 morning for example, perhaps be later than service time, 9: 2 morning for example, controller 110 is opened switch 130 and is offered the power supply of the variable filter amplifier 80 of radio frequency, demodulator 90, decoder 100 and GPS 140 with disconnection, thereby reduces power consumption.In this state, controller 110 is constantly to check the current time from timer 170 next cycle service time, prepares simultaneously to extract regional informations from memory 150.
If the time period in appointment provides information, for example from, and do not use above-mentioned regular service scheme in 9: 40 of nine thirty to mornings in the morning, the user also obtains regional information by the service time section is set in controller 110.During this time, whether controller also belongs to the service time section according to current time of timer 170 and closes or cut-off switch 130.
Above just for description and interpretation the preferred embodiments of the present invention, therefore, without departing from the spirit and scope of the present invention, those skilled in the art can change, variants and modifications.
