According to the industrial intelligent control system based on software definition provided by the invention, computing power optimization scheduling and dynamic reconstruction can be realized in a software definition manner, resources are allocated to different industrial control tasks and edge computing tasks as required, and an edge intelligent controller with differentiated control and computing capabilities is constructed; meanwhile, a real-time industrial control task and a non-real-time edge intelligent calculation task are supported, and the method has great significance and practicalvalue for improving the utilization rate of industrial edge equipment resources, improving the overall edge service capability and reducing energy consumption. Besides, real-time control and non-real-time computing task requirements of industrial intelligent control, edge computing, industrial AI and the like can be met, platform capabilities of an edge side and a cloud side are broken through, the method has the advantages of fusion, intelligence, real-time performance and flexible expansion, and a brand-new solution which is efficient, differentiated, low in cost, space-saving and easy to maintain is provided for industrial intelligent control.
