Hereinafter, with reference to the accompanying drawings will be described in more detail the present invention.

1 is a block diagram of an automatic guide broadcasting apparatus using a satellite positioning system according to the present invention. The apparatus of FIG. 1 includes a GPS receiver 10, a control unit 12, a storage unit 14, a display unit 16, and a voice output unit 18.

The GPS receiver 10 receives satellite orbit information from a plurality of GPS satellites and generates position data indicating the current position of the vehicle using the received satellite orbit information. The detailed configuration of the GPS receiver 10 is described in US Pat. Nos. 4, 114, 155 and the documents cited therein.

The control unit 12 includes a microprocessor, inputs current location information determined from the GPS receiver, compares the preset announcement location information with each other, and reads the matching announcement location information and corresponding announcement information from the storage unit. The video data of the read guide information is provided to the display unit, and the audio information is provided to the audio output unit.

As shown in FIG. 3, the storage unit 14 stores guide broadcast position information, for example, guide broadcast information corresponding to the stop position information P1, P2, P3,-, Pn. In addition, it is also possible to store geographic indication information of all stops passing from the starting point of the vehicle to the destination. The storage unit 14 includes a semiconductor memory such as a RAM, a ROM, a flash memory, a magnetic disk such as an FDD or an HDD, an optical disk such as a CD-ROM, and the like, and the broadcast information may be compressed and stored.

The display unit 16 is configured with a display device such as an LCD or an LED to display image data of the announcement information by text or graphic. It is also possible to display the running position of the current vehicle together with the geographical indication of all stops between the vehicle's origin and destination.

The voice output unit 18 converts the voice information of the announcement information into an analog signal, and outputs the converted analog voice signal through the speaker.

The operation of the present invention configured as described above will be described with reference to the flowchart of FIG. 2.

First, when power is turned on, the device initializes the system (100). Subsequently, the satellite orbit information transmitted from the GPS satellites is received through the GPS receiver 10 at a predetermined time interval (102), and the distance between the vehicle and each satellite and the current position of the satellite are obtained using the received satellite orbit information. The calculation determines the current position of the vehicle (104). The determined current position information is transmitted to the control unit 12.

The controller 12 compares the determined current position information Pc with a plurality of preset announcement position information and checks whether there is matched announcement position information P1, P2, P3, ---, Pn ( 106).

If there is no matching announcement location information in step 106, step 102 is performed. If there is matched announcement location information, for example Pc = P1, the controller 12 reads announcement information from the storage unit 14 from the corresponding storage location, for example, P1 location (108). The video data among the read guide information is transmitted to the display unit 16 to be displayed by text or graphic processing, and the audio data is transferred to the audio output unit 18 to be converted into an analog audio signal. It is output through 110. After the announcement is output, step 102 is performed again.

When the next position P2 existing between the stops P1 and P3 is reached, the advertisement announcement broadcast inserted in advance is output.

As described above, in the present invention, since the GPS receiver 10 determines the current location information of the vehicle and performs corresponding guide broadcast in response to the location information, the guide broadcast can be automatically and accurately performed without manual intervention of the driver.

The present invention can be applied not only to the above-mentioned bus stop announcements of city buses but also to announcement broadcast systems such as express buses and tour buses.

For example, in the case of express buses, announcements can be made to the destination when entering the expressway, announcements for the stop office immediately before arrival at the rest stop and announcement announcements for the destination immediately before arrival at the destination, etc. You can also broadcast commercials.

In addition, in the case of a sightseeing bus, it is possible to automatically broadcast the announcement of the time required to travel to the tourist destination and the tourist schedule after the bus departs, the announcement of the stopover just before arrival, and the farewell announcement after the tour.

In addition, the present invention is not limited to the vehicle, but may be configured as a personal portable guide device. The personal portable tourist information broadcasting device is used to describe the cultural property by identifying the cultural property when each person carries the device and plays quiet music in the state of wearing headphones or earphones, and reaches the location of a specific cultural property or tourist attraction. By automatically guiding and broadcasting general guide information of tourist attractions, the effect of tourism can be maximized.

As described above, in the present invention, when not only the vehicle but also a portable item that can be carried by an individual reaches a preset position, the current position can be grasped by a GPS receiver so that the guide broadcast stored in the storage medium can be automatically output. It is possible to maximize the effect of the guidance broadcasting because it is convenient to use and various applications are possible because of the precise control of the guidance broadcasting.
