1) triggering and processing an avionic control command: a user triggers an avionic control event through a control key, and calls a related control method to judge whether the avionic control event belongs to an avionic control instruction I, if not, the avionic control instruction is II, otherwise, the avionic control instruction is I; setting corresponding control logic variables, and refreshing the avionic control trigger module and the prompt message display module; triggering an avionic time event by a timer period, calling a related control method to read the current time BC: time-minute-second (H: M: S), and converted into millisecond data T _ data ═ (H × 3600+ M × 60+ S) × 1000 × 25;
2) and packaging and sending the avionics control message block: calling a processing avionic control interface to combine 1553B data words according to a 1553B communication protocol by bit logic XOR operation, and packaging the 1553B command words in a configuration message time sequence linked list into avionic control message blocks to be written into a 1553B board card BC message buffer area; calling an aperiodic message detection interface to detect whether a message block is sent in the current message linked list or not, if so, continuing to detect, and otherwise, calling an aperiodic message sending interface to write the avionic control message block into a 1553B board card; judging whether the writing message block is successful, if not, reporting and sending failure prompt information, otherwise, reporting and sending success prompt information; and releasing a message block in a 1553B bus board card buffer area, and continuously waiting for triggering the avionics control event.
