Multi-level task classification processing method, device and system and storage medium

The embodiment of the invention discloses a multilevel task classification processing method and device, an Internet of Things system and a storage medium. The method comprises the steps that the task state in the multi-core Internet of Things system is monitored, each execution core of the multi-core Internet of Things system is correspondingly distributed with one section of a first-in first-out cache queue, and the first-in first-out cache queue is further provided with a priority cache interval; when monitoring that the latest task input exists, caching the task to a corresponding cache interval according to the task priority so as to correspondingly distribute a processing mode; the execution cores are proportionally distributed into two types according to the number of the priority tasks; the first class obtains new tasks from the corresponding common cache interval for processing, and the second class sequentially obtains tasks from the priority cache interval and the corresponding common cache interva
