Technical Field

The present invention relates to the technical field of the Internet of Things (loT), specifically to an loT system based on embedded systems and edge computing.

Background Technology

Edge computing refers to moving computation and data storage to the edge of the network, i.e., devices or terminals, to significantly enhance response speed and reduce network bandwidth requirements. Embedded systems, on the other hand, are small-scale computer systems embedded within computer hardware or mechanical devices, specifically designed to perform dedicated functions and control tasks. The synergy between these two technologies drives the development of intelligent loT systems. As the data volume processed by embedded systems continues to grow and rapid response is increasingly demanded, the support of edge computing becomes essential. Similarly, edge computing relies on embedded systems to acquire data and control devices. Therefore, the close collaboration between these two technologies is critical to achieving intelligent loT systems.

The microcontroller unit (MCU) serves as the core of loT terminals (UE), undertaking functions such as sensor sampling, filtering, fusion computation, communication, and actuator control. MCU manufacturers often provide voluminous reference manuals, ranging from hundreds to nearly a thousand pages. Many manufacturers also offer software development kits (SDKs). However, application developers of MCUs often spend excessive effort on low-level drivers, and the development approach for terminal UEs suffers from issues such as low granularity in hardware-software development and weak portability.

Traditional hardware development involves low granularity. In conventional hardware designs for NB-loT terminal UEs, the process begins by selecting an MCU, a communication module, and an eSIM card. Based on the functionality of the terminal

UE, developers proceed with designing the minimum MCU system, communication 7600786 adaptation circuits, eSIM card interfaces, and other application functionalities, which are in urgent need of optimization.
