    The present invention relates to a data processing method between time-lapse V-Cal and quad split board. In the VCR microcomputer, the VCR microcomputer checks the Q flag generated in the quad microcomputer when the display playback key is input from the key input unit. It is determined whether or not it is a data transmission flag. If the Q flag is a data non-transmission flag in the determination step, the switching IC in the time-lapse VCR is short-circuited to control the display data according to the playback key to be reproduced. The V flag generated by the VCR microcomputer is converted into a data non-transmission flag, and the switching IC is opened. In addition, when described in terms of the quad micom, when the display data photographed by a plurality of cameras are input, the quad micom checks the V flag to determine whether it is a data transmission flag. When the V flag is the data non-transmission flag in the determining step, the display data is outputted. When the output of the display data is completed, the Q flag is converted into the data non-transmission flag. Therefore, a data collision does not occur between the microcomputers, so that data communication between microcomputers is normally performed.

    [16] Hereinafter, an embodiment according to the present invention will be described in detail with reference to the accompanying drawings.
    [17] Referring to FIG. 1, a block diagram illustrating a data processing method between a time-lapse VCR and a quad split board according to the present invention includes a key input unit 10, a time-lapse VCR 20, and a quad split board 30. And a monitor 40.
    [18] The key input unit 10 provides the display playback key to the time-lapse VCR 20 according to the function of the button input by the user's selection.
    [19] The time-lapse VCR 20 is a block including a VCR microcomputer 22 and a switching IC (IC). The VCR microcomputer 22 has a quad split board 30 when a display playback key is input from the key input unit 10. The Q flag generated in the quad microcomputer 32 is checked to control the switching IC 24 to be a short circuit in the case of a data non-transmission flag. Thereafter, the VCR microcomputer 22 controls the display data according to the playback key to be provided to the switching IC 24, and then displays it on the monitor 40 through the 8-bit data bus S1 in the switching IC 24. When the data output is completed, the V flag is converted into a data non-transmission flag, and the switching IC (IC) 24 is controlled to be open circuit.
    [20] The switching IC 24 is a block that is switched according to the short-circuit and open control of the VCR micom 22. The switching IC 24 is short-circuited according to the short-circuit control of the VCR micom 22, and then the display provided from the VCR micom 22. The data is output to the monitor 40 through the 8-bit data bus S1 and the quad display controller 34.
    [21] The quad split board 30 is a block including a quad micom 32 and a quad display controller 34. The quad micom 32 is a VCR microcomputer when the display data captured by the plurality of cameras S2 is input. When the V flag generated at 22 is checked to control the data non-transmission flag, the display data is controlled to be provided to the quad display controller 34 via the 8-bit data bus S1, and then the quad display controller 34 is controlled. When the output of the display data to the monitor 40 is completed, the Q flag is converted into a data non-transmission flag.
    [22] The quad display controller 34 provides display data provided from the quad microcomputer 32 to the monitor 40.
    [23] The monitor 40 outputs the display data provided under the control of the VCR microcomputer 22 and the quad microcomputer 32 for the user to view.
    [24] Referring to the flowchart of FIG. 2, the operation of the data processing method between the time-lapse VCR and the quad split board according to the present invention will be described in more detail based on the above-described configuration.
    [25] First, referring to the side of the VCR microcomputer 22 in the time-lapse VRC 20, the user uses the key input unit 10 to display the display play key to view the display data recorded in the time-lapse V-CAL 20. Enter (step 201).
    [26] Then, when the display playback key is input from the key input unit 22, the VCR microcomputer 22 checks the Q flag generated by the quad microcomputer 32 in the quad split board 30 to determine whether it is a data transmission flag ( Step 202).
    [27] If the Q flag is a data non-transmission flag in the determination step 202, the switching IC 24 is controlled to be short circuited (step 203).
    [28] After the switching IC (IC) 24 is short-circuited, the VCR microcomputer 22 provides the recorded display data to the short-circuit switching IC 24 (step 204), and the switching IC 24 ) Provides the display data provided from the VCR microcomputer 22 to the quad display controller 34 via the 8-bit data bus S1 (step 205).
    [29] When the Q flag is the data transmission flag in the determination step 202 or when the display data output to the monitor 40 is completed through the 8-bit data bus S1 in the switching IC 24, the V flag is set to the data. It converts to a non-transmission flag and controls the switching IC 24 to be open circuit (step 206).
    [30] The quad display controller 34 provides the display data provided from the VCR microcomputer 22 to be output to the monitor 40 (step 207).
    [31] The monitor 40 outputs the display data provided under the control of the VCR microcomputer 22 for the user to view (step 208).
    [32] Next, referring to the side of the quad micom 32 in the quad split board 30, after the user installs a plurality of cameras S2, display data captured by the plurality of cameras may be input to the quad micom 32. In the case (step 301), the quad microcomputer 32 checks the V flag generated in the VCR microcomputer 22 to determine whether it is a data transmission flag (step 302).
    [33] If the V flag is the non-data transmission flag in the determination step 302, the display data captured by the plurality of cameras is controlled to be provided to the quad display controller 34 via the 8-bit data bus S1 (step 303). .
    [34] When the V flag is the data transmission flag in the determination step 302 or when the quad display controller 34 completes the output of the display data to the monitor 40, the Q flag is converted into the data non-transmission flag (step 304).
    [35] The quad display controller 34 provides the display data provided from the quad microcomputer 32 to be output to the monitor 40 (step 305).
    [36] The monitor 40 outputs the display data provided under the control of the quad microcomputer 32 for the user to view (step 306).
    [37] Therefore, referring to the 8-bit data and the control waveform shown in FIG. 3, display data (eg, VCR data and the V flag generated in the VCR microcomputer 22 and the Q flag generated in the quad microcomputer 32). QUAD data) is normally provided to the monitor through an 8-bit data bus S1.
    [38] Therefore, the present invention allows data to be transmitted / received while checking the counterpart flag between the integrated time-lapse VCR and the quad split board internal micom, so that there is no data collision between the micro-communications and data communication between the micro-coms is performed normally. .
