LIN bus scheduling method and device, equipment and storage medium

The invention discloses an LIN (Local Interconnect Network) bus scheduling method which comprises the following steps: when a main node schedules an event frame in a main scheduling table, detecting whether a preset sub-scheduling table scheduling condition is met or not; wherein a master scheduling table and a sub scheduling table are preset in the master node, and the scheduling condition of the sub scheduling table is that an event trigger frame in the master scheduling table is responded by the slave node, and the response indicates that the master node needs to trigger and schedule the corresponding sub scheduling table; when the scheduling condition of the sub-scheduling table is met, switching the scheduling sequence of the main node from the main scheduling table to the corresponding sub-scheduling table; scheduling the sub-scheduling tables according to a preset scheduling sequence; and after it is detected that the sub-scheduling table completes scheduling, switching the scheduling sequence of the m
