Solid state disk wear leveling method, device and equipment based on reinforcement learning

The invention provides a solid state disk wear leveling method, device and equipment based on reinforcement learning. The method comprises the steps that when the number of free blocks in the solid state disk is lower than a set threshold value, the number of erasure times of all the blocks in the solid state disk at the current moment is obtained; calculating the erasure frequency standard deviation of each block at the current moment; obtaining the utilization rate of each block at the previous moment; according to the erasure frequency standard deviation of each block at the current moment and the utilization rate of each block at the previous moment, calculating an award obtained by the block after the block recovery operation is performed on the solid state disk at the previous time; screening out at least one to-be-erased block by utilizing a reinforcement learning algorithm according to a reward obtained by each block after the block recovery operation is performed on the solid state disk last time; an
