Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a transmission/reception system for selectively transmitting/receiving map information and lifestyle information to/from moving objects such as vehicles, pedestrians, etc.

(Conventional technology and problems) Traditionally, information boards, billboards, etc. have been used as a means of obtaining map information or product information on streets, etc., but the number of installations is limited, and it is necessary to confirm by actually seeing it with the naked eye. was there. In particular, map information has the drawback of having to confirm it with the above-mentioned guide, etc., and then relying on memory after moving from that location. Furthermore, there are so-called navigation/yeon/stem systems for vehicles, but they have a drawback in that they have a limited memory capacity and cannot necessarily store sufficient map information. On the other hand, the information inside the building is very limited, such as the location of the sales floor on each floor in the building, and information on product status, etc. It is necessary to check the information board at the entrance, etc.
When there was a large amount of product information, memory could become vague. Additionally, the Captain System is a means of transmitting such product information, but it has the disadvantage that it is a dog-based system and is not suitable for mobile use.

(Means for Solving the Problems) In the device example of the information transmitting/receiving system of the present invention, the transmitter section is
In the figure, the receiver section is shown in FIG.

1 is a transmitting antenna, 2 is a transmission output section, 3 is a modulation section, 4 is a scanning section for sequentially transmitting information, and 5 is a memory on the transmitter side for storing daily life information such as map information and product information. It is. 6 is a receiving antenna, 7 is an RF multiplication unit, 8 is a demodulation unit, 9 is a signal processing unit, 10 is a selection unit, 11 is a frame memory for temporarily storing information, 12 is a control unit, 13
is the display section.

In the transmitter section of FIG. 1, various types of information are stored in the memory of the transmitter 5 in ROM according to content, and the scanning section 4 sequentially scans and transmits this information. Therefore, the information in the memory is converted from parallel information to serial information and sent out, and the signal is input to the modulation section. This modulation section converts the information signal data into an RF signal, which is sent to a transmission output section 2 and radiated as a radio wave from a transmission antenna 1. On the other hand, in the receiver section of FIG. 2, the digitally modulated RF signal is received by the receiving antenna 6, and the RF amplification section 7 performs ILF amplification to a sufficient level for demodulation.
The signal is converted into serial digital signal information by the demodulator section 8. 9
The signal processing unit has the role of extracting information for each content, and extracts necessary data according to a command from the selection unit and stores it in the frame memory. On the other hand, the control section of l2 is
The information data required for the display section is selected from the frame memory and displayed on the display section. Therefore, since only the necessary portion of the transmitted signal is received by the receiver and captured into the frame memory, only the desired information can be selected.

(Example) Examples of the present invention will be specifically described below.

The information sent from the transmitter section in FIG. 1 has a frame structure as shown in FIG. 3, and map information near the sign post can be received at all times. On the other hand, adjacent map information and lifestyle information can be selected on the receiving side, and when the desired adjacent map or lifestyle information is selected, these pieces of information are imported into the frame memory. The frame memory on the receiving side consists of a map reception memory near the sign post that can be read at all times, and a memory that can be read by selection. Regarding nearby map information, map information and place name information for each bronc are usually displayed on the display device as shown in Figure 4, and Hitsune's address information is stored in memory, but the display device does not display it. It does not appear. By selecting this address information on the receiving side, it will appear on the map. On the other hand, the daily life information is displayed as shown in FIG. 5 by selecting the desired information. Since there is a limit to the display images of this information as well, the contents of the desired life information name will appear one after another by selection.

On the receiver side, when you come near a sign post and enter the reception range of the sign post's antenna, it first receives map information near the sign post, and the display device displays a map of the area near the sign post and the place name of each block. . Then, when the address is manually pressed using the external key, the address position 14 is displayed as a spot as shown in FIG. Next, if you want to obtain the desired lifestyle information, enter the desired lifestyle information number etc. using the external key in the same way as above, and the menu for that, for example, if it is a restaurant, the store name and address will be displayed as shown in Figure 5. It will be displayed as follows.

If it is not in the display field, the contents will be changed sequentially by inputting from the search key. In this way, desired information can be searched. On the other hand, regarding map information, if there is no map near the sign post, an adjacent map is displayed on the display device by operating the input key.

(Effects) As explained above, in addition to displaying the map information in the vicinity of the sign post on the display device based on the information signal from the sign post, it is also possible to receive and display a map of the adjacent area upon request. Moreover, by selecting lifestyle information, it can be sequentially imported, which has the effect that the memory capacity of the receiving device can be reduced. or,
Signposts can be installed not only on outdoor roads but also inside buildings, so the transmission/reception system of the present invention can also be used to display sales floors in department stores, etc., eliminating the need to search for information boards and incorporating product information. is possible.
