Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention transmits advertisement data such as images to one or a plurality of electronic signboards from an outdoor mobile or fixed transmitting station by radio waves or light and displays them on an electronic signboard display section. The present invention relates to a digital signage system for commercial advertising.

[0002]

2. Description of the Related Art Advertising signs for goods and companies are placed on the rooftops of buildings and buildings, alongside roads or in fields on both sides of railroad tracks, and are made large enough to be seen by as many people as possible. There is. When the display contents of the signboard are rewritten, it is done by manually repainting (A) or reattaching (B) as shown in FIG. FIG. 6 shows a conventional electronic signboard 1 installed on the roof of the building 10. This electronic signboard is LC
The display contents of the electronic signboard 1 are set by the operator operating the display control device 12 provided in the control room 11 of the building 10 or the like. It Therefore, the display content is changed under the control of the display control device 12.

[0003]

However, at present, the number of advertising billboards is extremely large, and in the case of changing the above-mentioned conventional display contents by paint or pasting,
As the contents are changed in a very short period of time, labor costs are very high. Even in the case of an electric display type signboard, a relatively large-scale dedicated control device is required for each of them, and if the number increases, the equipment cost becomes enormous. Further, in this case, there is a problem that it is difficult to install it in a place where there is no space, such as a sign at a platform of a station or a track.

The object of the present invention is to reduce the labor cost and time required for rewriting a conventional advertising signboard, and to rewrite the contents displayed on the signboard from a remote location, which makes it difficult for humans to directly enter. An object of the present invention is to provide an electronic signboard system capable of avoiding work in a dangerous place or a small place.

[0005]

An electronic signboard system of the present invention is provided with a display controller for receiving a radio signal and outputting an image signal, and a display device for displaying a screen according to the image signal. And a transmission station that transmits a wireless signal modulated with compressed image data to the display control unit, wherein the display control unit receives the wireless signal and extracts the compressed image data, and A data processing unit that performs decompression processing on the compressed image data and outputs decompressed image data, a memory that stores the decompressed image data, and a transmission that transmits a reception end or resend request to the transmission station. Section, when the wireless signal is received, the compressed image data is taken out from the receiving section and input to the data processing section to perform a decompression process, and the decompressed image data is stored in the memory. And a control unit for reading the stored image data and giving it as the image signal to the display device, wherein the transmitting station inputs the image data to be displayed on the display device and converts the image data into compressed image data. A data input unit, an image data memory in which the compressed image data is stored, a transmission / reception unit that modulates and sends a radio signal using the compressed image data as a modulation wave, and the transmission / reception unit that reads the compressed image data from the memory And a control operation unit for transmitting a radio signal from the transmission / reception unit, and is configured to set and update the screen display of the display unit of the electronic signboard device by the radio signal from the transmission / reception station. It is a feature.

Further, an electromagnetic wave or light is used as the radio signal, and the transmitting station is a transmitting station movable on land or a transmitting station fixed on land. It is what

FIG. 1 is a block diagram showing an embodiment of the present invention. In the figure, 1 is a display device serving as a signboard part, 2 is a display control part, 3 is a mobile transmission station, and 4 is a fixed transmission station. The display control unit 2 includes a receiving unit 5 that receives advertisement data sent from the transmitting station 3 or 4, a transmitting unit 6 that sends information to the transmitting station 3 or 4, and a data processing unit 7 that processes received data.
And a memory 8 for storing processed data, and a controller 9 for controlling each of the above-mentioned units (reception unit 5, transmission unit 6, data processing unit 7, memory 8). The transmitting station is a mobile or radio base station, and the medium for data transmission is radio waves or light. The display device 1 and the display control unit 2 constitute an electronic signboard device 20.

FIG. 2 is a block diagram of the transmitting station 3 or 4 in the present invention. In the figure, 31 is a transmission / reception unit, and 32 is
Is an image data memory, 33 is an image data input unit, and 34 is a control operation unit. The compressed image data is written from the image data input unit 33 into the image data memory 32.
By the operation from the control operation unit 34, the transmission / reception unit 31 reads out the memory contents from the image data memory 32, and a radio wave in which a transmission carrier wave is modulated by using it as a modulation wave is transmitted from the antenna.

The data transmitted from the transmitting station 3 or 4 is compressed image data or the like, and the data processing unit 7 performs data decompression processing. The data sent from the transmitting unit 6 to the transmitting station 3 or 4 is a response signal for notifying the transmitting station 3 or 4 of the reception end or the retransmission request. The restored image data is stored in the memory 8, and the contents are displayed on the display device 1.
Is displayed in. The power supply for each signboard is supplied from the building to be installed for the signboards installed in buildings and other buildings, and is supplied from the nearby distribution lines for the other signs, and there is no distribution line in the vicinity. In the area, it is supplied by a private power generation device such as a battery or a solar cell. Illustration of this power source is omitted.

FIG. 3 is a diagram for explaining the operation of the present invention and shows the operation by one mobile transmitting station 3. One mobile transmitting station 3 moves on the road and transmits display information from near the electronic signboard device 20 or the self-supporting electronic signboard device 20 'on the roof of the building 10 to change the display contents simultaneously or sequentially. To do.

FIG. 4 is another operation explanatory view of the present invention.
(A) is a zone 2 where one transmitter station 3 is at one point
This is a case where the display contents of the plurality of electronic signboard devices 20, 20 ', 20 "in 1 are sequentially changed. (B) One fixed transmitting station 4 has a plurality of electronic signboard devices 20 in the zone 22 at that point. , 20 ', 20 "are changed simultaneously or sequentially.

[0012]

The effects of the present invention are as follows. (1) Since the signboard unit and the display control device are integrated to reduce the scale and the equipment cost is low, it is suitable for installing a large number of signboards. (2) Since a large number of signboards can be rewritten with a small number of personnel in a short time, the display change cost can be reduced.
