The user interface unit 327 is characterized in that the RS-232C port for the administrator to directly connect to the interface so that the program can grasp the download and the state of the second MCU (321).

Referring to the operation of the electronic sign control device according to the present invention configured as described above are as follows.

First, referring to the application of the data from the first control means 140, the manager is a computer interface through the process of compressing or editing the data of the electronic display board 400, that is, software or other advertising data in the computer 120, etc. When applied to 146, data applied through the PC interface 146 is first stored in the memory unit 144 via the first MCU 141.

The first MCU 141 first checks the current communication state whether the second control means 320 can receive data through the radio base station 200 through the antenna 142a of the first CDMA module 142. .

When it is determined that the current communication line state is good through the first CDMA module 142, the manager issues a command to the first MCU 141 of the first wireless transmission / reception unit 140 through the computer 120. The first MCU 141 receives the command and transmits data stored in the memory unit 144 to the second control means 320 via the wireless base station 200 through the first CDMA module 142.

Data transmitted by the first wireless transmission and reception unit 140 is applied to the second wireless transmission and reception unit 320 of the second control means 300, the second CDMA module 322 of the second wireless transmission and reception unit 320. Is applied through the antenna 322a.

Data applied to the antenna 322a of the second CDMA module 322 is applied to the second MCU 321 and stored in the memory unit 324 again.

The data stored in the memory unit 324 is first determined whether the existing data and the current data are the same data in the second MCU 321, and when the determined data is determined to be the same as the current data, the data is stored. If not, the second MCU 321 applies the data when it is determined that the data is updated compared to the current data.

The criterion for determining whether the data is existing data or not is to determine whether the data is updated data by using a unique number of a version. The reason for comparing and determining the data is due to an error of an administrator. This is to prevent the immediate application of data or old data.

In addition, the data stored in the memory unit 324 is converted into analog data that is digitally input through the modem monitoring unit 328, and directly from the second MCU 321 to the driving unit 410 of the electronic display board 400. By applying a so that it can be displayed directly on the electronic sign 400.

When the second MCU 321 updates the data stored in the memory unit 324, the data is not stored in the memory unit 324 but stored in the EPI 325 so that the second MCU 321 stores the data even when the power is cut off. This is to prevent loss.

In addition, the Watts Dock Timer 323 monitors in real time whether an error occurs when the second MCU 321 updates data or whether the update is properly performed without a current error, and the second MCU 321 monitors the data in real time. Through the authorization to the first wireless transmission and reception unit 140 to allow the administrator to check this on the computer 120.

If an error occurs during the update, it is applied to the second MCU 321 so that the administrator knows what error is currently occurring due to the first wireless transmitter / receiver 140 through the second CDMA module 322 in the second MCU 321. To transmit data.

The error state is checked by the Watts Dock timer 323 because a constant signal is continuously transmitted at a predetermined time interval due to the characteristics of the Watts Dock timer 323, when the signal is not continuously applied, The computer can notify the administrator because it recognizes the off state or another error condition.

When the status is determined by the data applied by the Watts Dog Timer 323 to determine the presence or absence of an error state to inform the administrator, the administrator to restart the operation of the power to the electric signboard 400 at a remote location, If an error is detected even during re-operation, the manager carries the first CDMA terminal 160 and moves to the electronic display board 400 in which the error has occurred.

The wirelessly applied data is again applied to the driver 410 of the electronic display panel 400 by the second MCU 321. At this time, the analog signal converted by the modem monitoring unit 328 is applied to the advertisement. Expresses.

In addition, when the administrator is moving without being monitored from a remote location, the data is applied to the first CDMA terminal 160 through the wireless base station 200, which is displayed on a screen (not shown). If the license is properly applied, the phone number of the second CDMA terminal 340 is displayed on the first CDMA terminal 160 so that the administrator can know that the power is currently applied.

In the standby state, the level of RF is present and the current state is displayed in text, and when dialing, a text indicating that the user is currently making a call, and when the call is received, 'RECEIVING' is displayed as a text. Lets the administrator know that you are receiving a call.

When the second CDMA terminal 340 is connected, the text status is displayed as 'ON LINE' and indicates that the first CDMA terminal 160 is connected to the administrator so that the administrator can check the connection. Display the character 'CLOSING ...' to indicate that the current connection has been terminated.

If an error occurs when the administrator attempts to connect again through the first CDMA terminal 160, the administrator stops using it further and displays the letter 'ERROR' so that the administrator can respond immediately. will be.

The electronic sign 400 may be applied to any electronic sign 400 regardless of its size, and the data (advertisement, software) of the electronic sign 400 without replacing the driving unit 410 of the existing electronic sign 400 is installed. Etc.) can be upgraded.

As described above, data is applied to the computer 120 and the first CDMA terminal 160 so that the current state of the electronic display panel 400 is transmitted in real time, and the first CDMA terminal 160 is located where the data is applied. Since the number is inputted from the electronic display board 400 and the position can be accurately identified, the administrator can manage the various electronic display boards 400 with one computer 120 or the first CDMA terminal 160. It is.

In addition, since the text is transmitted when data is applied, it is inexpensive to spend, so it is very easy to manage.

The configuration of the signboard of the present invention is not limited as shown in the drawings, but the drawings and the contents described in the present specification are only examples for the sake of better understanding based on an embodiment. Can be.

Looking at the effect of the signboard control device according to the present invention, the signboard control device according to the present invention is capable of monitoring and controlling the status of various equipment installed in the signboard by the two-way communication, the short-term Sending messages has the effect of knowing where in the world the failure occurred.

In addition, it can be efficiently managed at a low cost during maintenance of the signboard, and there is an effect that can prevent unnecessary waste of power because the power to the signboard is controlled at a remote location.

In addition, since the communication state can be checked in real time, more stable data is applied when data is applied, thereby preventing an error due to data transmission.
