Embodiment

[0085] This embodiment discloses a research method for equipment failure early warning and life prediction system, its structure is as follows figure 1 , figure 2 , all the steps of the present embodiment are all based on the Matlab development environment and the Orcle database, and the method specifically includes the following steps:

[0086] S1. Use SQL statements to establish database relational tables and store them in the Oracle database. Matlab connects to the Oracle database through the ODBC bridge to access data and complete the database construction;

[0087] The steps are as follows:

[0088] S101, such as image 3 , Figure 4 , Figure 5 According to the requirements of the plan, use SQL statements to write the equipment health assessment table ELEIDX, the fault diagnosis table FAULTDB, and the data point table ELE format, and build the original interface point table select into a series of relational tables, which are stored in the Oracle database for storin...

Abstract

The invention discloses a fault early warning and life prediction method of escalator equipment. The method calculates the health status of an escalator system according to each module status of the escalator, the escalator health status is compared with the escalator abnormality time fitting function, the escalator operation time is obtained, and the remaining life of the equipment can be calculated according to a failure threshold of the escalator corresponding to the escalator operation time. According to fault early warning and life prediction method of escalator equipment, all kinds of algorithms adopted are designed based on equipment index analysis, the escalator index in algorithms is changed to other equipment indexes, the real time index data of the corresponding detection equipment is collected, so that the health evaluation status and the remaining life of the detection equipment. Therefore, the algorithm system is suitable for the prediction of each key equipment, and hasthe commonality.

Description

technical field [0001] The invention relates to the technical fields of acquisition of fault characteristic information, processing of information uncertainty, and massive data analysis and processing, and in particular to a fault early warning and life prediction method for elevator and escalator equipment. Background technique [0002] Equipment failure early warning and life prediction According to equipment operation rules or observed possible precursors, it can timely and accurately predict the abnormal condition of equipment before the equipment actually fails, and take corresponding measures to minimize the loss caused by equipment failure. Ensure the safe and stable operation of the equipment. Therefore, it is particularly urgent to use reliable condition monitoring technology to monitor and diagnose process abnormalities in a timely and effective manner. [0003] Existing equipment failure early warning technologies are mainly divided into three categories: method ...
