Task synchronization method and device, equipment and medium

The invention discloses a task synchronization method and device, equipment and a medium. The method comprises the following steps: filling to obtain a task information table according to task information of each task in a target process sent by software, and filling to obtain a task dependency table according to a dependency relationship between each task and other tasks; setting the first task to be in a dependency relationship locking state; updating the task information table in real time, and updating the dependency relationship of each task in a dependency relationship locking state in the task dependency table; whenever it is detected that the second task in the dependency relationship locking state does not have the dependency relationship with other task items, the second task is set to be in a dependency relationship relieving state, and the task in the dependency relationship relieving state is sent to a next-level task execution mechanism through a task transmitting module. By the adoption of the
