Elevator safety risk assessment method and system and storage medium

The invention discloses an elevator safety risk assessment method and system and a storage medium. The method comprises the following steps: obtaining feature data and operation data of all elevators in a preset period; calculating accumulated operation times according to the operation times and the elevator number; calculating the average occurrence probability according to the characteristic event data of all the elevators and the accumulated operation times; calculating a statistical occurrence probability according to the characteristic event data and the operation times of the single elevator; calculating a relative occurrence probability according to the average occurrence probability and the statistical occurrence probability; according to the relative occurrence probability, the severity feature vector and the influence degree weight vector, calculating the original risk value of the elevator; and performing safety risk assessment on the elevator according to the original risk value of the elevator.
