Data transmission method and system based on ARINC659 bus, electronic equipment and storage medium

The invention provides a data transmission method and system based on an ARINC659 bus, electronic equipment and a storage medium, and the method comprises the steps: dividing a transmitting end window and a receiving end window of the ARINC659 bus into a buffer area A and a buffer area B, respectively assigning the address of an update target corresponding to the buffer area, and setting the initial value of the update target as 0; when the sending end sends packet data, the updating marks corresponding to the two buffer areas of the window of the sending end are read respectively, the packet data to be sent currently is written into the corresponding buffer area with the small updating mark value, and 1 is added to the updating mark value of the corresponding buffer area; when the receiving end reads data, the updating marks corresponding to the two buffer areas of the window of the receiving end are read respectively, and packet data sent in the period are read from the corresponding buffer area with the la
