A power control and resource allocation based task offloading method in an industrial Internet of Things. The method comprises: establishing computation models for computation tasks at different offloading positions; constructing a mixed integer non-linear programming model by using communication power control, resource allocation and computation unloading problems; and finding a solution by using a deep reinforcement learning algorithm to obtain the optimal policy for offloading the computation tasks, so as to realize communication power optimization and cross-domain resource allocation.
