Research on the fusion scheduling of functional safety and information security of relay protection device based on priority

Abstract

To solve the problem of fusion scheduling of relay protection device functional safety and information security, the measures of relay protection device functional safety and information security are selected based on the analysis of relay protection device safety requirements. The priority of each measure is analyzed and a priority-based fusion scheduling scheme of functional safety and information security is proposed. On the STM32F407ZG platform, the safety tasks are managed using the μC/ OS-II embedded operating system, and the safety tasks can be executed correctly.
