However, such a conventional requestable information providing apparatus, when requested by each user, individually transmits information data corresponding to the request, and therefore, for example, traffic In the case of information such as information that has a high degree of commonality (common information), the same information data is requested by a number of different users, and therefore the same information is transmitted many times. As a result, the load of the transmission device increases, large-scale equipment is required, the burden on the user increases, and the use efficiency of radio waves decreases.

The present invention has been made in view of the above-mentioned conventional problems, and can reduce the load on the transmitter, reduce the burden on the user, effectively use radio waves, and facilitate the operation of extracting desired information. It is an object of the present invention to provide a vehicle-mounted information receiving device that can be realized.

[0008]

According to the present invention, there is provided an in-vehicle information receiving device for receiving information transmitted from an external information transmitting device in response to a user request and displaying the information on a display device. Receiving means for receiving the information, storage means for storing the received information, reception completion determining means for determining whether or not the information corresponding to the request is stored in the storage means, and the determination result for displaying the above. And a display means for displaying on a container.

[0009]

According to the on-vehicle information receiving device of the present invention, the information received by the receiving means is stored in the storage means.
Then, whether or not there is information corresponding to the request in the stored information is determined by the reception completion determination means,
The determination result is displayed on the display by the display means.

As described above, when the information is requested, it is determined whether or not the information has already been received. Therefore, if the information is already received, the load on the transmitting device can be reduced by not requesting the information, and the radio wave can be used effectively. Available.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. 1 to 4 are diagrams for explaining an in-vehicle information receiving device according to an embodiment of the present invention, FIG. 1 is a diagram showing a configuration of an information transmitting device for transmitting information to the receiving device, and FIG. FIG. 3 is a diagram showing the configuration of the receiving device, FIG. 3 is a flowchart diagram for explaining the operation of the transmitting device, and FIG. 4 is a flowchart diagram for explaining the operation of the receiving device.

In FIG. 1, reference numeral 1 denotes an information transmitting apparatus, which is a modem 4 for receiving a request from an individual user 2 of a specific group via a telephone line 3 and an instruction for periodically updating common information described later. An information updating console 5 to be operated, a transmission information database 6 for recording transmission information,
It is provided with a CPU 7 for reading out predetermined transmission information from the database 6 based on the request information and instruction information for regular update from the console 5. The read transmission information is transmitted to the pager transmission station 10 via the telephone line 9 via the modem 8.

Reference numeral 19 denotes an in-vehicle type information receiving device mounted on an automobile, which is a pager receiver 11 for receiving information data transmitted from the pager transmitting station 10.
And a memory 12 for storing the received data and the like, a CPU 13 for reading the information data stored in the memory 12 as necessary, and a navigation device for performing an operation of reading information from the CPU 13 and displaying data 14,
And a display (display) 15. Reference numeral 16 is a remote control device that wirelessly operates the navigation device 14 via an infrared receiver 17, and the remote control device 16 functions as a tone dialer that sends a request to the modem 4 via a telephone 18. The navigation device 14 may be used as the remote control device 16 and the telephone 18.

Next, the operation of the receiving device 19 will be described with reference to FIG. First, when information is requested by the remote control device 16, the request number of the information is input to the navigation device 14 (step S1). Then, it is determined whether the request information has already been received in the memory 12 (step S
2) If it has not been received, a message requesting a request is displayed on the display 15 (step S3). If the information has already been received, a message to that effect is displayed, and then the information is displayed on the display panel 14 (steps S4 to S5).
In this case, the pager receiver 11 serves as a receiving means.
The CPU 13 functions as a reception completion detecting unit, the memory 12 functions as a storage unit, and the navigation device 14 functions as a display unit.

Next, the operation of the information transmitting apparatus 1 will be described with reference to FIG. First, it is determined whether or not the individual user 2 of the specific group has requested information to the information transmission device 1 (step S6), and if there is a request, a user ID and a request code number are acquired in the CPU 7 ( Step S7). In this case, the user ID and the request number are input by a push operation as a tone dialer of the remote controller 16.

Then, the CPU 7 determines whether or not the request is for common information (step S8), and when it is for individual information having low commonality of needs, information corresponding to the request is determined. It is read from the database 6, an individual call corresponding to the user ID is added, and the pager transmission station 10 transmits the individual call to the specific user 2 (step S9). Therefore, in this case, only the specific user 2 corresponding to the individual call can receive the transmitted information and is displayed on the display 15 of the specific user 2.

Here, in the apparatus of this embodiment, traffic information and the like are transmitted at predetermined time intervals, and emergency information and the like are arbitrarily transmitted from the information transmitting apparatus 1 to all users by simultaneous broadcast, The data of the wide area information (common information) in the memory 12 of the automobile is constantly updated to the latest data.

When the request from the user 2 is for the common information in step S8, it is then determined whether this information has been transmitted by the above-mentioned data update (step S10). Then, if the data is already transmitted, the process proceeds to step S6. If the data is not already transmitted, the common information is broadcast to all users by the data update and the common information identifies the specific user 2. It is transmitted together with the number (step S11). Then, the information is displayed only on the display panel 14 of the specific user 2 having the ID number.

As described above, when the information is requested, it is detected whether or not the information is already received. Therefore, if the information is already received, the request can be prevented from being requested, and the same information can be repeatedly requested and transmitted. This can be avoided, the load on the transmitter can be reduced, and the radio waves can be effectively used. Further, even for the information transmitted by the above-mentioned simultaneous transmission, it is possible to request the transmission again for the information not received due to the poor radio wave condition or the like.
