In the case where a plurality of billboards are installed in a predetermined area and the same information is to be displayed through each billboard, remote controller operation is cumbersome since the same data input process must be repeated by operating all remote controllers corresponding to each billboard. .

In addition, in the case of a conventional electronic sign control remote control it is impossible to store the data, so even if the data entered in the past is input again and transmitted to the electronic sign, it is inconvenient to repeat the same data input process every time. There is also a problem that can not be confirmed in advance on the remote control screen.

Accordingly, the present invention has been made to solve the conventional problems as described above, and it is possible to input and transmit image data, to preview the input data, and to store and recall data, and to control a plurality of electronic signs. It is an object of the present invention to provide a remote controller for controlling a signboard.

According to a preferred embodiment of the present invention for achieving the above object,

After the user switches the operation mode of the remote controller 100 to the data input mode in a state in which various image data downloaded from an external device is pre-stored in the font storage unit 140 of the remote controller 100 (step S201), the remote controller ( When the character to be displayed on the electronic display panel 200 is input by operating the key input unit 110 of step 100 (step S203), the microcomputer 130 may convert a character font corresponding to the operation of the key input unit 110 into a font storage unit ( It reads from the 140 and transfers it to the driving unit 150. Then, the driving unit 150 converts the character font into predetermined graphic data and provides it to the display unit 160 to display the character input by the user on the display unit 160 of the remote controller 100 (step S205).

As a result, this process is repeated and each character input by the user is displayed on the display unit 160 of the remote controller 100. If the user manipulates the key input unit 110 to insert an image stored in the remote controller 100 in advance. When an image input key signal is generated (step S207), the microcomputer 130 switches the operation mode of the remote controller 100 to the image data input mode in response thereto. Then, each image data previously stored in the font storage unit 140 is read out and provided to the driving unit 150 so that each image data is displayed on the display unit 160 (step S209). Accordingly, the user may select an image to be input by searching for each image displayed on the display unit 160.

If the user manipulates the key input unit 110 and selects an arbitrary image from each image displayed through the display unit 160 (step S211), the microcomputer 130 recognizes the selected image as input data and drives the drive unit ( The display unit 160 displays the display unit 160 through step 150 (step S213).

As a result, by repeatedly performing the above-described steps S203 to S213, the user can input image data as well as a desired character.

Then, when the input of the data stream consisting of a predetermined character and / or image is completed through each of these processes, the user operates the key input unit 100 to input the input completion signal, the microcomputer 130 based on this It is recognized that the data input process is completed (step S215).

Subsequently, when the user desires to scroll left and right or up and down while the data input by the user through the remote controller 100 is displayed on the electronic sign 200, the user may designate scroll information, that is, scroll direction and scroll speed. . Therefore, when the user inputs the scroll information on the data input through the above-described processes through the key input unit 110 of the remote controller 100 (step S219), the microcomputer 130 recognizes the scroll information and the user Is set as scroll information for the input data (step S221).

In the state in which a predetermined text and / or image and scroll information about the same are inputted through each of these processes, if the user wants to check the screen displayed on the electronic display through the remote controller 100, the remote controller 100 This is enabled by using the preview key button provided in the key input unit 110. If the user manipulates the key input unit 110 to input the preview key signal (step S221), the microcomputer 130 performs the above-described process and the data stream input by the user is displayed on the display unit through the driving unit 150. To be displayed at 160. At this time, if scroll information is set through the above-described step S219, the driving unit 150 is controlled to scroll the displayed data stream based on the scroll information (step S223). Therefore, the user can first check the screen to be displayed on the display board 200 through the display unit 160 of the remote controller 100.

Subsequently, when the user inputs a transmission key signal by operating the key input unit 110 to transmit the data stream input by the user to the electronic display 200 (step S225), the microcomputer 130 may operate the key input unit 110. Based on the transmission key signal input through the above-described process, the data stream input by the user is converted into graphic data in pixel units and transmitted to the wireless transmitter 170. In this case, if the scroll information is set through the above-described step S219, the scroll information is inserted into the graphic data and transmitted together.

The wireless transmitter 170 converts the graphic data provided from the microcomputer 130 into a wireless signal and transmits the converted graphic data to the electronic sign 200 (step S227). In this case, if there are a plurality of signboards and wants to transmit the data stream input through the above-described processes to the plurality of signboards, it is possible by inputting serial numbers for the signboards as described above.

Meanwhile, the wireless receiver 210 of the electronic sign 200 receives a wireless signal transmitted from the remote controller 210, and the controller 220 extracts graphic data and scroll information from the received wireless signal and displays the display driver 240. To pass. In addition, the display driver 240 drives the display unit 250 based on the graphic data and the scroll information provided from the controller 220 so that the data stream (text and / or image) input by the user through the remote controller 100 may be changed. To be displayed.

In the above-described step (S225) has been described a case in which the user inputs the data to the electronic sign 200, in the present invention, the input data is stored in the remote control 100, and then called later on the electronic sign ( It also supports the function of sending to. In this case, in operation S225, the user operates the key input unit 110 to store the data input to the remote controller 100 without transmitting the data currently input to the remote controller 100 to the electronic sign 200. When the signal is input (step S229), the microcomputer 130 stores the data input by the user, that is, a data stream composed of characters and / or images, in the font storage unit 140 (step S231). At this time, if the user sets the scroll information for the data together, the scroll information is stored together. In addition, the data stored in the font storage unit 140 of the remote controller 100 may be called when necessary and edited and transmitted to the electronic display board 200.

3 is a flowchart illustrating an overall process according to a case where data input by a user through the above-described step S231 of FIG. 2 is stored in the remote controller 100 and then called and transmitted to the electronic display panel 200. to be.

If a key signal for calling a pre-stored data stream is input by operating the key input unit 110 (100) (step S301), the microcomputer 130 reads the data stream stored in the font storage unit 140 in response thereto. Therefore, the predetermined list is transmitted to the driver 150. Then, the driving unit 150 displays the data list on the display unit 160 so that the user can select a desired data stream from each data stream included in the list (step S303).

If the user selects an arbitrary data stream from each of the data displayed on the display unit 160 and inputs a selection signal according thereto (step S305), the microcomputer 130 extracts only the selected data stream in response to the driving unit ( 150). In this process, when scroll information about the data stream is set, it is transmitted to the driving unit 150 together. Therefore, the data selected by the user is displayed on the display unit 160 under the control of the driving unit 150, and as a result, the preview function for the data stream selected by the user is executed (step S307).

Through this process, in the state in which any data stream previously stored in the remote controller 100 is selected and displayed on the display unit 160, the user may modify (edit) the displayed data stream or transmit the data stream to one or more display boards.

If the user manipulates the key input unit 110 to input a key signal for data correction (step S309), the microcomputer 130 switches the operation mode of the remote controller 100 to the data editing mode in response thereto. By repeating the process after step S203 of FIG. 2 according to the user's key manipulation, the data stream is modified and transmitted to the electronic sign 200 or stored again.

On the contrary, when the user operates the key manipulation unit 110 and inputs a transmission key signal according to the data stream without modifying the data to the electronic sign 200 (step S311), the microcomputer 130 selects in response thereto. Convert the data stream into graphic data in pixels. The graphic data is transmitted to the wireless transmitter 170. Of course, if the scroll information for the data is set in this process, the microcomputer 130 inserts the scroll information into the graphic data and transmits the same. The wireless transmitter 170 converts the graphic data provided from the microcomputer 130 into a wireless signal and wirelessly transmits the graphic data to the electronic sign 200 (step S313). Of course, in this process, as in the above-described transmission process in FIG. 2, when there are a plurality of electronic signs, and the data (characters and / or images) input through the aforementioned processes are transmitted to the plurality of electronic signs, the corresponding electronic signs This is done by entering a serial number for.
