The communication table controller 301 stores the communication information input from the user in the periodic / aperiodic communication tables 104, 201, and 202 (S301), and performs the corresponding periodic / aperiodic communication table as a result of correctly storing the communication information ( The information index 203 recorded in 104 is returned (S302). At this time, when the input communication information is aperiodic communication information (S303), the aperiodic communication controller 305 obtains the aperiodic communication information from the periodic / aperiodic communication table 104 (S304) through the 1553 bus. Aperiodic communication is performed (S305).

When the inputted information information is periodic communication information (S303), the periodic communication controller 302 sets an interrupt service routine (ISR) of the system timer 102 to periodically transmit communication information every few seconds. (S306) A time period (ISR) of the interrupt processor 106 is set to determine how many seconds the interrupt input from the first controller 108 is processed (S307). The minor frame manager 105 configures a minor frame according to a communication period of each communication information stored in the periodic / aperiodic communication table 104 in short period, middle period, and long period. (S308), the configured minor frame is written into the command block 109 (S309).

Next, the communication control unit 103 is connected to the system timer 102 (S310), and executes communication through the 1553 bus (S311).

At this time, the system timer controller 303 reads the signal of the system timer 102 to determine the cycle and phase of the current system timer 102 (S312), and the same communication cycle as the cycle and phase of the system timer 102. The communication information 212 having the 208 and the phase 209 is identified (S313), and according to the result of the system timer controller 303, the minor frame manager 105 has the same communication period 208 as the system timer 102. Command block 109 is modified so that communication is performed only for the communication information 212 having the phase 209 and the phase 209 (S314). A method of modifying the command block 109 as described above will be described in more detail with reference to FIG. 5 below.

Then, the first controller 108 transmits the communication information 212 in the modified command block 109 through the 1553 bus (S315), and updates the processed data in the shared memory 107 (S316). .

The interrupt controller 304 confirms the interrupt of the first controller 108 according to the time period of the interrupt handler 106, and indicates that the data processed by the first controller 108 has been updated in the shared memory 107. 101) (S317).

If there is a communication with phase 413 in each period, the arrangement of the communication is arranged in the order input from the user.

Thereafter, as shown in FIG. 6, communication with no phase 413 difference is performed first in each cycle by the execution of the command block 109, and communication with phase 413 is performed before the next cycle is performed. Therefore, referring to FIG. 6, the execution of communication in a short period is performed in the order of A-1 402, A-3 404, and A-2 403. Execution of communication in the medium cycle is performed in the order of B-1 406, B-2 407, and B-3 408.

When called, the communication information is executed, and when jumped, execution of the communication information is passed.

The minor frame manager 105 identifies the communication information for each period by the system timer controller 303 and modifies the minor frame communication information in the command block 109 using a call or a jump.

Once all communication has been processed, it is returned to start communication again, waiting for the next system timer 102 signal.

FIG. 6 is a flowchart illustrating a configuration of a minor frame and a communication execution procedure in the command block 109 by the communication control unit 103 and the minor frame manager 105 according to an exemplary embodiment of the present invention.

Referring to FIG. 6, the minor frame in the command block 109 is programmed by the communication control unit 103 and the minor frame manager 105 just before each periodic communication starts. When each periodical communication is initiated, the 1553 bus communication begins as the minor frame is set in the command block 109, after which minor frame configuration programming is performed for the next periodical communication.

When aperiodic communication information is input, the aperiodic communication controller 305 takes the aperiodic communication information from the periodic / aperiodic communication table 104 so that the aperiodic communication is executed immediately. After the aperiodic communication is completed, the periodic communication continues afterwards.
