Description

technical field

[0001] The invention relates to the field of elevator risk assessment, in particular to an elevator risk assessment system. Background technique

[0002] In related technologies, there are many systems for elevator risk assessment, such as an elevator risk assessment system based on fuzzy analytic hierarchy process and artificial neural network, and a comprehensive safety assessment system for elevator systems based on multi-layer comprehensive evaluation mathematical model statistics. However, the weights of the systems in related technologies are mostly based on expert experience, resulting in insufficient accuracy of evaluation results and effectiveness of applications. Although elevator problems are common, they are difficult to characterize and evaluate. As a result, government supervision, maintenance by maintenance units and accident prevention can only be judged based on experience. The current situation of weak supervision, untimely maintenance and i...

Examples

Embodiment 1

[0041] see figure 1 , figure 2 , a kind of elevator risk assessment system of the present embodiment, comprises:

[0042] (1) Elevator risk assessment index hierarchy generation module 1, for adopting AHP to analyze the factors that may cause elevator failure, and set up elevator risk assessment index hierarchy; Described elevator risk assessment index hierarchy is evaluated by elevator failure It is formulated by an expert group of factors, which includes a target layer, a criterion layer and an index layer. The target layer is defined as the hazard to be evaluated, and the criterion layer includes the probability of the hazard occurring, and the degree of influence of the hazard after the hazard occurs. and three parent indicators of uncontrollability, the indicator layer includes various sub-indicators corresponding to the parent indicators, in which the safety measures or strategies adopted by the system are considered to reduce and control the risk, and the uncontrollab...
