Abstract

The invention discloses an elevator risk assessment system. The elevator risk assessment system comprises an elevator risk assessment index hierarchical structure generation module, an information acquisition module, a weight calculation module, a remark definition module, a membership matrix construction module, a risk assessment module and a risk analysis module. According to the invention, the fuzzy matrix, the artificial neural network and the analytic hierarchy process are employed in the elevator risk assessment, various uncertain factors and indexes which occur in the risk assessment process can be analyzed, the elevator running state can be assessed timely, sensitively and reliably, and a relatively-accurate risk grade of an elevator target floor can be given out quickly.

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...
