The invention relates to a method of the avalanche-proof of an industrial automation system. The industrial automation system comprises a storage unit used for storing time steam data unit to be processed and a CPU processing the time steam data inside the storage unit. The invention comprises the following steps: first, the establishment of data task priority; second, the CPU data task scheduling; third, the use approach of the storage unit. Under the fixed CPU processing ability, the invention sets the priority rank to the time stream data to be processed. The CPU preferentially processes the data task to be processed with the highest priority rank, and then processes the data task to be processed with lower priority rank. The storage units also set the corresponding sub-storage units with different priority ranks according to the priority rank of the data task to be processed. The data to be processed with the highest priority rank is able to store or cover the data to be processed with lower priority rank, thereby effectively ensuring that the automation system processes the task with the unpredicted quantity under the fixed CPU processing ability without causing the deadlock of the system.
