In view of the problems existing in the current Internet of Things technology,this paper makes an in-depth discussion on it,aiming at integrating all its underlying components into one software,so as to realize the development and optimization of low energy consumption and product-level Internet of Things devices.First of all,the functional design based on thread control,thread synchronization,thread communication and other modules is completed.Then,the interrupt control and storage management of the embedded Internet of Things system are realized.A variety of communication modes and protocols of the embedded Internet of Things system are realized.Finally,the low power consumption of the embedded Internet of Things system is tested.The test results show that the more functionality provided by the system will increase the power consumption of the system without using the operating system,but in the low power and normal working state,its power consumption is 50% of that of the ordinary microcomputer.
