The invention discloses a dynamic risk management and control method and
system for an operation process and field interaction equipment, and relates to the technical field of
industrial internet,
machine vision and
intrinsic safety control. The invention aims to solve the technical problems that the physical state and the digital approval in the existing
job management are disjointed, the existing
job management is easily attacked by
multimedia data fraud (such as screen
copying and historical photo forgery), and the control instruction is lagged in a dynamic environment. The method comprises the following steps: a
system and a field controller establish bidirectional
heartbeat monitoring based on a hardware watchdog, and equipment is set in a physical locking state by default; responding to the operation request, and acquiring
multimedia evidence containing a bottom hardware level tamper-proof space-time
fingerprint by utilizing a hardware security unit (SE) of the field interaction equipment; the authenticity and the space-time legality of hardware fingerprints are verified at first, and then moire detection, reflection analysis and semantic comparison are conducted through an AI
algorithm; and only when the anti-counterfeiting and the content
verification are both passed, generating an
encryption driving
signal to unlock. During operation, a state competition
processing mechanism is introduced, if the environment is suddenly changed, the
system preferentially suspends the authority through high-priority hardware interruption, and fault-oriented security (Fail-Safe) is achieved. According to the invention, through deep fusion of
software and hardware,
active defense and
millisecond-level dynamic fusing of operation risks are realized.
