As one of the most basic and most critical devices in the perception layer of the ubiquitous power Internet of Things, smart energy meters require high reliability, low cost, and low power consumption, as well as certain functional expansion capabilities. This article mainly focuses on the smart energy meter integrating the metering and billing functions with variable tariffs and flexible and expandable electricity price packages, and analyzes the requirements for MCU instruction set, kernel structure, and SOC peripherals of this type of smart energy meter when working with a lightweight microkernel real-time operating system. And put forward the key design of the main frequency and large-capacity storage, which can meet the basic functions of the smart energy meter, while meeting the needs of flexible and expandable functions.
