Major safety risk index measurement model

The invention discloses a major safety risk index measurement model. The major safety risk index measurement model includes unit inherent danger index metering, unit risk management and control index metering and unit dynamic index metering. The metering of the unit inherent danger index is a place personnel exposure index weighted accumulated value of the inherent danger indexes of a plurality of risk points; the initial high-risk risk management and control frequency of the unit and the inherent risk index of the unit are aggregated to obtain an initial high-risk safety risk value of the unit; the unit dynamic index metering comprises high risk monitoring characteristic index metering, safety production basic management dynamic index metering, special period index metering, high risk Internet of Things index metering and natural environment correction index metering; and the unit initial high-risk-safety risk value is corrected by using the unit dynamic index metering value to obtain a unit real risk value.
