AbstractThree issues should be addressed in ubiquitous power Internet of things (IoT) terminals, such as lack of terminal standardization, high business coupling and weak local intelligent processing ability. The application of operating system in power IoT terminals provides the possibility to solve the above problems, but needs to address the real-time and security problems. In this paper, TrustZone based virtualization architecture is used to tackle the above real-time and security problems, which adopts the dual system architecture of real-time operating system (FreeRTOS) to run real-time tasks, such as power parameter acquisition and control on the real-time operating system, to solve the real-time problem; And non real-time tasks are run on the general operating system(Linux) to solve the expansibility problem of power terminals with hardware assisted virtualization technology achieving the isolation of resources, ensuring the safety of power related applications. The scheme is verified on the physical platform. The results show that the dual operating system power IoT terminal scheme based on ARM TrustZone meets the security requirements and has better real-time performance, with unifying terminal standards, business decoupling and enhancing local processing capacity.
