When performing various perception, control and data processing tasks, these devices have put forward increasingly stringent requirements on computing resources, storage resources and communication bandwidth, especially in scenarios with multiple concurrent tasks and fierce resource competition. Simply relying on static configuration can no longer meet the needs of efficient and reliable operation. How to achieve fine-grained, dynamic and intelligent resource management and task scheduling while ensuring the overall performance of the system and the efficiency of task execution has become a technical problem that needs to be solved urgently in the current Internet of Things operating system.

[0003] The foregoing discussion of the background art is intended only to facilitate an understanding of the present invention. This discussion does not acknowledge or admit that any of the material referred to is part of the common general knowledge.

These systems generally include: application layer, protocol layer, data link layer and communication layer; the application layer is used to collect field signals and transmit them to the IoT terminal and protocol layer; the protocol layer assembles the original data collected by the application layer and converts the protocol format, generates numbers, verification data, encryption and encryption methods, and transmits them to the server of the IoT terminal; the data link layer schedules the data received from the protocol layer and sends it to the communication layer using a priority scheduling algorithm; the input end of the communication layer is connected to the server of the IoT terminal, and each functional module is processed in layers; the data link layer schedules and distributes the data content, and operates the specific communication module to reduce the difficulty of operating the communication module. However, this system is only used to realize the basic functions of the IoT, and the operation of the equipment in the IoT is not optimized, and the system operation efficiency needs to be improved. Summary of the invention
