Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a remote control display device for changing the display contents of a display device at a remote location.

[0002]

2. Description of the Related Art Conventionally, for example, in supermarkets and the like, LED (light emitting diode) displays and the like have been used for advertising of various products. This type of display device has a central processing unit (CPU) 1 as shown in FIG.
A ROM 2 such as a P-ROM (programmable read only memory) that stores a certain display content connected to the CPU 1; and a RAM that stores temporary data.
It consists of a (random access memory) 3 and a display control unit 4 and a display unit 5 such as an LED. The display contents stored in the ROM 2 are repeatedly read and displayed on the display unit 5.

[0003]

In the conventional LED display device, the display contents are stored in the ROM 2. Therefore, when the display contents are changed, new display contents are individually input for each display device. Or, it is necessary to replace it with the ROM 2 which stores new display contents, and it takes time and effort to change the display contents, and it is not possible to freely change the display contents in real time. Therefore, for example, it is difficult to timely advertise a specific product at the time of shopping in the evening, or to finely advertise a product in accordance with different times for each region.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a remote control display device by wireless communication, which can freely change the display contents of the display devices arranged in each area from a remote place.

[0005]

In order to achieve the above-mentioned object, a remote-controlled display device of the present invention comprises a wireless receiver for receiving display data. Further, in a display device operated by remote control, a display device equipped with the wireless receiver is arranged for product advertisement in a store, and display data from a display content changing unit centrally managed via a teleterminal system is displayed. To receive.

[0006]

According to the present invention, since the display device is provided with the wireless receiver for receiving the display data, the display can be easily changed in real time. In addition, a display equipped with a wireless receiver is placed for product advertisements in stores, and it is placed in each region by receiving display data from the display content change unit that is centrally managed via the teleterminal system. The display contents of the display device can be freely changed from a remote place at any time, and the advertisement can be timely performed, or the advertisement can be finely tuned at different times for each region.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be specifically described below with reference to an embodiment shown in the drawings. FIG. 1 is a view for explaining a remote control display device according to an embodiment of the present invention.

In FIG. 1, a remote-controlled display device by wireless communication according to the present embodiment has a display device 11 equipped with a wireless receiver arranged in each predetermined area, and wirelessly transmits data to the display device 11. A teleterminal system 12 comprising a shared use center 12a and a radio base station 12b,
The shared use center 12a of the teleterminal system 12 and the headquarters computer 14 for transmitting the display contents for each display 11 and the administrator terminal 15 for managing the change of the display contents are connected via the network 13. It In the administrator terminal 15, the display content to be changed is input to each display device 11, data such as a regional code and display time, and is transmitted to the head office computer 14. The headquarters computer 14 transmits data via the teleterminal system 12 for each display 11 according to the content transmitted from the administrator terminal 15. The display unit 11 that has received the change contents displays the change contents at the designated time.

FIG. 2 is a block diagram for explaining the configuration of a display device equipped with the wireless reception device of the embodiment of the present invention, and FIG. 3 is a perspective view showing the appearance of the display device equipped with the wireless reception device of the embodiment of the present invention. is there.

In FIG. 2, the display 11 is, for example, a display using an LED as a display element, and C
PU 16 and RAM for recording display contents transmitted from the headquarters computer 14 and data to be temporarily recorded.
17, a display control unit 18 and a display unit 19 for controlling data of display contents, and a wireless reception device 20. The wireless reception device 20 includes a receiving unit 21 that receives wireless data sent from the wireless base station 12b, a communication control unit 22 that controls communication data between the receiving unit 21 and the CPU 16, and an antenna 23. It is configured. Further, in FIG. 3, the display device 11 of the present embodiment is, for example,
A vertically long display unit body 24 is installed by a stand 25, and an antenna 2 for receiving wireless data is provided on the back side.
3 is attached, and for example, the display contents are sequentially and repeatedly scrolled and displayed.

FIG. 4 is a flow chart for explaining the operation at the administrator terminal of the display device by wireless communication according to the embodiment of the present invention.

In the figure, first, in the administrator terminal 15, data such as display contents to be changed, codes for each display, codes for each region, and display time are input (ST1).
Next, the input data is converted into a transmission format for wireless transmission (ST2). Then, the converted data in the converted format is transmitted to the head office computer 14 via the network 13 (ST3). The data received by the headquarters computer 14 is sent to the network 1 according to the instruction content sent from the headquarters computer 14.
3 and the teleterminal system 12 to the display 11 in each area.

According to the above configuration, the display content to be changed, the code for each display, the code for each area, and the data such as the display time, which are input by the administrator terminal 15, are transmitted from the head office computer 14 to the network 13 and the teleterminal system. It is transmitted to the display device 11 in each area via 12 and this display device 11
In the case of (1), it is received by the wireless reception device 20, stored in the RAM 17, then read out under the control of the CPU 16 at a predetermined time, and displayed on the display unit 19 under the control of the display control unit 18. You can freely change the display contents in real time. Therefore, if such a display device 11 is placed in a supermarket, for example, a specific product can be advertised in good timing at the time of shopping in the evening, or a product can be advertised at different times for each region. It becomes possible to make it fine. In the conventional display device, the contents recorded in the ROM were displayed, so the ROM had to be replaced in order to change the display contents. However, this embodiment does not require this, and the display contents can be easily changed at any time. I can do it.

In the above embodiment, the administrator terminal 1
The example in which the change contents input in step 5 are transmitted to the headquarters computer 14 and then transmitted from the headquarters computer 14 to each display unit 11 has been described. Data may be transmitted via the system 12 and is not limited to the embodiment.

Further, the display device 11 is used as a display element for an LED.
However, not limited to this, various electronic display devices such as plasma displays, fluorescent display tubes, liquid crystal displays, etc. can be used, and the shape of the display is also provided on the stand. Needless to say, it may be similar to the electronic bulletin board.

[0016]

As described above, according to the present invention, the contents of the change inputted by the display contents changing section are transmitted through the teleterminal system, and the display provided with the radio receiver arranged in each area. By being received by each machine, you can freely change the display content in real time from a remote location at any time, and you can make timely advertisements or make detailed advertisements at different times for different regions. Is effective.
