Problems solved by technology

[0002] With the development of the economy, there are more and more high-rise buildings in cities. As a convenient and efficient means of transportation, the use and frequency of elevators have greatly increased. Therefore, whether the elevator can operate normally and safely is very important to us. The elevator safety protection system is the core component of whether the elevator can operate safely. When the elevator fails, whether the elevator safety protection system can work normally to ensure the safety of the elevator It is particularly important. However, the safety risk of the elevator safety protection system is a very complex and comprehensive system problem, which has its inherent ambiguity. Changes in the characteristics of elevators may change the results of the comprehensive evaluation. The qualitative changes caused by such small quantitative changes are sometimes di

Embodiment

[0079] Introduction to the elevator to be tested: This evaluation selects the elevator of an office building in City H as a case, which is denoted as G elevator.

[0080] Taking one of the index layer factors "speed limiter" as an example for specific analysis, the specific steps are as follows:

[0081] Step 1, establish the criterion layer and index layer, according to Table 1, we can know the criterion layer A 1 is the "speed limiter", and the index layer is the action reliability of the speed limiter A 11 , the lubricity of the rotating part of the speed limiter A 12 , completeness of speed limiter protection device A 13 ;

[0082] Step 2, establish an evaluation index set, criterion layer A 1 is the "speed limiter", and the index set is: A 1 =(A 11 ,A 12 ,A 13 );

[0083] Step 3, constructing a judgment matrix, see Table 8 for details;

Abstract

The invention provides an evaluation method for an elevator safety protection system based on a hierarchy-fuzzy method. The method comprises: firstly, recognizing risk factors of the elevator safety protection system, then hierarchical analysis is conducted through an analytic hierarchy process, and the weights of all criterion floors and index floors are calculated; secondly, on the basis of pre-risk analysis, further analyzing the component by applying a failure mode and an influence analysis method to judge the risk degree of the component so as to construct a risk membership matrix; According to the elevator safety protection system risk assessment method based on the fuzzy comprehensive evaluation, the risk degree of the elevator safety protection system can be visually, comprehensively and quantitatively determined, and suggestions are given according to the actually measured risk index values of the elevator safety protection system.

Description

technical field [0001] The invention relates to the field of elevator safety, in particular to an evaluation method for an elevator safety protection system based on a hierarchical-fuzzy method. Background technique [0002] With the development of the economy, there are more and more high-rise buildings in cities. As a convenient and efficient means of transportation, the use and frequency of elevators have greatly increased. Therefore, whether the elevator can operate normally and safely is very important to us. The elevator safety protection system is the core component of whether the elevator can operate safely. When the elevator fails, whether the elevator safety protection system can work normally to ensure the safety of the elevator It is particularly important. However, the safety risk of the elevator safety protection system is a very complex and comprehensive system problem, which has its inherent ambiguity. Changes in the nature of elevators may change the result...
