Embodiment approach 1

[0044] A real estate company in a residential area, according to the attached figure 1 The process of risk assessment for the elevators in the community. First, on the basis of literature review and expert experience interviews, the commonly used evaluation index analysis method Analytical Hierarchy Process (AHP) is used to analyze the factors that may cause elevator risks in a hierarchical manner, and finally 10 influencing factors are selected as elevator risks. evaluation indicators, and to establish figure 2 The elevator risk assessment indicator hierarchy shown. On the basis of the hierarchical structure of elevator risk assessment indicators, the existing mature computer technology is used to obtain the measured parameters of 20 elevator risk indicators, and the commonly used evaluation index membership function is used to initialize the sample data. Using the existing artificial neural network (ANN) method to establish a 10-6-1 3-layer neural network model, use 20 elev...

Abstract

The invention relates to an elevator risk evaluation method, and belongs to the technical field of elevator risk real-time evaluation and process and safety control. The elevator risk evaluation method comprises the steps that (1) an index analysis method and an analytic hierarchy process are used for analyzing factors which possibly cause elevator faults, and an elevator risk evaluation index hierarchical structure is built; (2) actually-measured parameter values of indexes of the elevator risk evaluation index hierarchical structure are obtained, and initialization processing is carried out on the actually-measured parameter values of the indexes; (3) the weight of the indexes of the elevator risk evaluation index hierarchical structure is determined through an artificial neural network; (4) risk evaluation is carried out on an elevator through a feed-forward neural network with a time sequence learning algorithm, and the elevator risk grades are divided. The elevator risk evaluation method has reference value and application value in a plurality of fields, and can be applied to risk evaluation of industrial boilers, large-sized power transformers, industrial pipelines and the like.

Description

technical field [0001] The invention relates to an elevator risk assessment method, which belongs to the technical field of elevator risk real-time assessment and process and safety control. Background technique [0002] With the rapid development of my country's economic construction and the rapid improvement of people's material and cultural living standards, the elevator is not only an important equipment in the production process, but also a necessary equipment in work and life. Elevators, like cars, are already Transportation equipment frequently used by people. The number of elevators in my country has increased from 285,000 at the end of 2001 to 1.63 million at the end of 2011, and is growing at a rate of about 20% every year. At present, China has the largest number of elevators in the world. The frequent elevator accidents in recent years have aroused the widespread concern of the government and all walks of life on the safety of elevators. According to the statist...
