This paper proposes a functional safety and information security protection mechanism based on blockchain technology.The design of the basic level and integration level blockchain structure of CPS distributed architecture and related functional safety and information security measures lycogel are introduced.An effective communication judgment mechanism based on functional safety error threshold is proposed, which is stored and judged by smart contract.And a refund transaction with a clock is proposed to ensure the effective execution of iphone 13 pro max price winnipeg the functional safety error threshold mechanism.The article takes cyber physical machine tool system as an example to describe the SIL judgment method of CPS physical equipment and functional safety loop and combines SIL with fault diagnosis and risk protection.

Finally, the rationality of our proposed mechanism is proved by information security, functional security, real-time and maintainability.
