Problems solved by technology

[0003] With the increase in the complexity of equipment, the monitoring of equipment operation often has the characteristics of many equipment monitoring points, high sampling frequency of monitoring points, and long data collection time, which makes the amount of operating data that needs to be processed by complex equipment fault diagnosis systems show an explosive growth. Big data at the scale of hundreds of terabits or even at the bit level is not uncommon

Abstract

The invention relates to an elevator fault prediction method based on big data learning, and provides a method for predicting and diagnosing faults of an elevator based on big data acquired through asensor during actual operation of the elevator. The elevator fault prediction method comprises the three aspects of association of elevator operation characteristic big data and operation reasons, acquisition of complex equipment operation fault characteristics based on big data analysis, and elevator operation fault prediction based on data learning. According to the elevator fault prediction method, big data is subjected to noise reduction treatment, more effective data is acquired, elevator operation parameters are analyzed, characteristic parameters are acquired, a depth neural network prediction model is established, and fault prediction is more accurate.

Description

Technical field [0001] The invention relates to the field of elevator fault diagnosis and prediction, in particular to an elevator fault prediction method based on big data learning. Background technique [0002] Fault diagnosis and fault prediction technology is one of the important technologies to ensure the safe and stable operation of complex equipment such as elevators. The fault diagnosis technology realizes the prediction and diagnosis of equipment operation faults through the monitoring of the equipment operation status and the analysis and processing of the corresponding data, and judges whether the equipment status is in an abnormal state, or the specific part or even the specific zero where the fault occurs. Components, predict the development trend of failures. This technology has been widely used in the operation monitoring and control of complex equipment such as large steam turbine units, aero engines, high-speed elevators, etc., and is listed as one of the nine ke...
