And a display board for displaying an electronic image under the display control of the control circuit section.

According to the second aspect of the present invention, the display device is configured as follows. That is, it has a transmission / reception function unit of the mobile phone terminal, and when a call signal to itself and an image signal following the call signal are transmitted from the radio base station side via a radio line, these signals are transmitted. And sends the image signal to a control circuit unit described later. When an alarm signal described later is sent from the control circuit unit, the alarm signal is sent to the wireless base station side via a wireless line. Based on the transmitting / receiving circuit unit to transmit and the image signal sent from the transmitting / receiving circuit unit, display control of a display board described later is performed, and the operation status of each circuit unit of the display device is grasped. When a failure or necessity of adjustment occurs in the circuit part, the control circuit part that sends an alarm signal indicating the failure or the necessity of adjustment to the transmission / reception circuit part, and performs display control of the control circuit part. Digit a configuration and a display board for displaying the electronic image.

That is, the point of the idea of the present invention is to control the display of the display device from a remote point or position by using a part of the function of the terminal of the portable telephone attached to the display device. .

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be specifically described below based on an embodiment shown in the drawings. FIG. 1 shows the configuration of the present embodiment. In FIG. 1, a mobile phone terminal 1 equipped with a transmitting / receiving antenna 2 is a mobile phone terminal for analog communication, and transmits a call signal to itself and a call signal from the wireless base station via a wireless line. When an analog image signal is transmitted, these signals are received, and the image signal is transmitted to the modem 5 of the control circuit unit 3. When an alarm signal described later is transmitted from the modem 5, And a circuit unit for transmitting the alarm signal to the wireless base station via a wireless line.

The control circuit unit 3 includes a control unit 4 and a modem 5
When an analog image signal is transmitted from the mobile phone terminal 1, the modem 5 converts these signals into digital signals and sends them to the control unit 4. When a signal is transmitted, the circuit unit converts the signal into an analog signal and transmits the analog signal to the mobile phone 1. The control unit 4 controls the display of the display board 6 described below based on the image signal transmitted from the modem 5 and grasps the operation status of each circuit unit of the display device. When a failure or the necessity of adjustment occurs in the circuit part, the alarm signal indicating the failure or the necessity of the adjustment is sent to the modem 5. The display board 6 is a large display board that displays an electronic image under the display control of the control unit 4.

Next, the operation of the above embodiment configured as described above will be described with reference to FIGS.
That is, as shown in FIG. 2, the analog image signal transmitted from the input / output device 10 is transmitted to the line 11, the exchange 12, the line 1
And transmitted to the radio base station 14 via the transmitting / receiving antenna 15 of the radio base station 14,
That is, it is transmitted through a wireless line and received by the mobile phone terminal 1 of the display device 16 (see FIG. 1). The image signal received by the mobile phone terminal 1 as described above is sent from the mobile phone terminal 1 to the modem 5, digitized by the modem 5, and provided to the control unit 4 as a digital image signal. The control unit 4 controls the display of the display board 6 based on the provided image signal. The display board 6 receives the display control of the control unit 4 and displays an electronic image such as an advertisement.

The control section 4 grasps the operating condition of each circuit section of the display device 16 and, when a failure or a necessity of adjustment occurs in any of the circuit sections, the failure or the necessity of the adjustment is required. A digital alarm signal is transmitted to the modem 5, and the alarm signal is converted into an analog signal by the modem 5 and supplied to the mobile phone terminal 1. The signal is sent to the station 14 and further applied to the input / output device 10 via the line 13, the exchange 12, and the line 11, and the input / output device 10 performs a notification operation according to the sent alarm signal.

As described above, in the display device according to the above-described embodiment, since the wireless line is used by using the portable telephone terminal without using the wired line, the installation position of the display device can be easily moved. In addition, when the display content is to be changed, it is only necessary to change the image signal input from the input / output device 10 to a new one, which can be performed very easily. Further, by the notification operation according to the alarm signal by the input / output device 10,
A failure or the like of the display device can be recognized without going to the installation position of the display device.

It should be noted that the scope of the present invention is not limited to the above embodiment, and various modifications and applications are possible. For example, in the above embodiment, the mobile phone terminal 1 is for analog communication, but may be for digital communication. In this case, the modem 5 is not required and the mobile phone terminal 1 and the control unit 4 Send and receive signals directly.
