On the other hand, the main apparatus 200 includes a handset 201, a liquid crystal panel 202, a button input means 203, a keyboard 204. Each component of the generation terminal 100 functions as follows.

That is, the data receiving end 117 and the data transmitting end 118 function to transmit and receive data with the main unit 200, and the data level recovery / conversion unit 116 receives the data received through the data receiving end 117 from the main unit 200. To remove the noise using a filter means and to process a complete square wave, output to the central processing unit 109 or convert the data applied from the central processing unit 109 to a level which can be transmitted using the amplifying means. It transmits to the main apparatus 200 side through 118.

The central processing unit 109 controls the overall operation of the generation terminal (100). That is, to the D / A converter 113 to control data transmission and reception with the main device 200, calculate and determine the synchronization signal applied from the synchronization signal separator 108, and display Korean characters in synchronization with the monitor 102. FIG. Font data output control, memory control of ROM 111 and RAM 112, button recognition input from button unit 104, and LED 103 flashing control are performed. The ROM 111 stores Korean fonts and / or other character fonts corresponding to the announcement data according to a predetermined rule, and outputs them according to the command of the central processing unit 109. RAM 112 functions to store announcement data. The D / A converter 113 converts the Hangul and / or other character font data applied from the central processing unit 109 into an analog signal and outputs it to the monitor 102 through the video signal output terminal 107 (Table) 1). The monitor 102 displays the announcement, and the LED 103 flashes under control of the central processing unit 109 when the announcement is stored in the RAM 112 to inform the user that the announcement is stored. The button unit 104 is provided with a predetermined function key such as an announcement confirmation button. The synchronizing signal separator 108 separates the horizontal and vertical synchronizing signals of the monitor and transmits information about the horizontal and vertical coordinates on the monitor to the central processing unit 109 so that the output of Hangul and / or other characters is output to the monitor 102. Make it possible. In addition, the monitor on / off stage 105 is a terminal for transmitting the on / off signal applied from the central processing unit 109 to the monitor 102 side, and the video signal input / output terminals 106 and 107 transmit a notice or the like to the monitor 102. This is a terminal to input and output signals for display.

In the video phone system configured as described above, first, when command and announcement data (hereinafter, abbreviated as “data”) are input to the main device 200 according to a predetermined protocol, the data is transmitted to the data transmission / reception line 301 with a predetermined bit code. It is transmitted to the generation terminal 100 through. The data transmitted in this manner is applied to the generation terminal 100 through the data receiving terminal 117, and the data is recovered by the data level recovery / conversion unit 116 and output to the central processing unit 109. The central processing unit 109 recognizes the data and stores the data in the RAM 112 and then flashes the LED 103 to inform the user that there is a notice. Thereafter, when the user inputs a notification confirmation button of the button unit 104 to confirm the announcement, the central processing unit 109 recognizes this and reads the Hangul font corresponding to the data stored in the RAM 112. It reads from 111 and outputs it to the monitor 102 side via the D / A conversion part 113, and displays it.

The series of processes will be described in more detail for each process as follows.

First, a process of inputting a notice to the main device 200 will be described. That is, when the notice is input to the main device 200, the key is input through the keyboard 204 according to a predetermined protocol. Examples of prescribed protocols are as follows.

T-1

T-2

An example of a process for inputting a notice for holding a subcommittee in the main apparatus 200 according to the above agreement is as follows (see FIG. 7).

First, the input button 203 of the main device 200 is pressed. Next, the user inputs I 5 (enter), which is a start-up holding command (command to display a Hangul message “holding-up meeting” on the generation terminal 100 monitor 102), through the keyboard 204, and then starts MS. Enter 07 (Enter), start date DS 25 (enter), start time TS 19:00 (enter), end time TE 20:00 (enter) in this order, and the Lake Ho H 101-701 (enter) will be held. Enter. At this time, it is possible to select whether to transmit the input data to all generations or only to transmit the input data to a specific generation, and this selection is made by the button input means 203. The selected number is coded and transmitted to each generation. In this example, the previous generation button 203 of the main apparatus 200 is input. As described above, the data inputted to the main device 200 through the keyboard 204 is transmitted to each generation terminal 100 through the bus line 303 in the form of a code composed of 8-bit instructions, 16-bit or more data, and 8-bit stop bits as shown in FIG. The data input through the keyboard 204 is converted into an ASCII code (see FIG. 9), so that the input data is transmitted in the form of ASCII code.

In more detail, the process of inputting the announcement data into the main device 200 is as shown in the left end of FIG. 7, and the matter displayed on the liquid crystal panel 202 of the main device 200 is shown in the right end of FIG. 7. As Data input through the keyboard 204 is converted into ASCII code to be applied to the main device 200, as shown at the top of FIG. 6, and the main device 200 shows the data at the bottom of FIG. As specified, it is sent to the specified generation in ASCII code. Here, the generation to transmit the data can be determined using a unique ID assigned to each generation. Determination of generation to be transmitted at the time of input of the data can be made through the button input means 203 or the keyboard 204 of the main device 200. In the former case, it is convenient for batch transmission of each generation, and in the latter case when transmitting individual generations. It is convenient. The generation designation data to be transmitted (data code for accessing each generation, mainly a unique ID, etc.) belongs to a command of the announcement data to be transmitted, and is particularly referred to as an input mode command. In addition, the input mode command is added to the first part of the data transmitted from the main unit 200 to each generation and transmitted to each generation, and the central processing unit 109 of each generation terminal recognizes the input mode command and receives data. Will be determined. In the example of FIG. 6, since it is necessary to transmit to the previous generation due to the nature of the announcement (holding the meeting), the previous generation calling instruction 10101010 _2, that is, AA ₁₆ is added as the input mode instruction. Well, a process in which data transmitted from the main device 200 is stored in the memory means of the generation terminal 100 will be described with reference to FIG.

First, the central processing unit 109 determines whether the data supplied from the main unit 200 is an input mode command (step 301). If the input mode command is input in step 301, the serially transmitted data is read by one byte (step 302), If the read data is an instruction (step 303), if the data read in step 303 is an instruction, the contents of the instruction are determined, the area to be stored in the RAM 112 is secured (step 304), and the subsequent data after the instruction is read one byte. (Step 305) After storing the data read after the step 305 is stored in the storage area of the RAM 112 secured in step 304 (step 306), the process returns to step 303 to perform the repeating operation. On the other hand, if the data applied from the main device in step 301 is not an input mode command, the process is repeated until an input mode command is applied (step 301). If the data read in step 303 is not an instruction (i.e., data), the operation of step 306 is performed. Do this.

When the announcement data is stored in the RAM 112 through the above process, the generation terminal flashes the LED 103 to inform the user that the announcement is stored. Hereinafter, a process of confirming the stored announcement data by the user will be described with reference to FIG. 4.

First, the central processing unit 109 notifies the user by blinking the LED 103 that the announcement data is stored in the RAM 112 (step 401), and then input of the confirmation button provided in the button unit 104 is performed. (Step 402). If there is a confirmation button input in step 402, the central processing unit 109 turns on the monitor 102 via the monitor on / off end 105 (step 403). The central processing unit 109 then counts the vertical and horizontal coordinates from the sync signal separator 108 to find the position to be displayed on the monitor 102 (step 404), and corresponds to the corresponding data stored in the RAM 112. A Korean font or the like is read from the ROM 111 and output to the monitor 102 via the D / A converter 113 for display (405). An example of a notice displayed on monitor 102 is shown in FIG. Thereafter, a check is made to see if there is an erase button input for erasing the currently displayed message from RAM 112 (step 406). If there is an erase button input, the data currently displayed on the monitor 102 is retrieved from RAM 112. (Step 407). Thereafter, it is determined whether there is an input of a confirmation button for confirming the subsequent message (step 408). If there is an input of the confirmation button, it is checked whether the subsequent message is stored in the RAM 112 (step 409). Returning to step 404, the repeat operation is performed. On the other hand, if there is no confirmation button input in step 402, the process returns to step 401, and if there is no input of the erase button in step 406, the process proceeds to step 408. In step 409, the next message is not stored in the memory means 112. Otherwise it will exit.

According to the present invention described above, in the case of delivering various notices to each household in the complex, such as in a multi-family housing complex, it is possible to deliver the notices to all households collectively by entering them once in the main unit installed in the guard room. Since it is possible to conveniently check the announcements without the need to simplify the announcement delivery process, the recognition of the announcements can also be significantly increased.
