The invention discloses a remote
fault analysis system and method for a negative pressure
station, and relates to the technical field of
big data analysis. Historical normal operation industrial parameters and fault maintenance information of the negative pressure
station are collected, and a unique
traceability identifier is added; the load working conditions are divided into high, medium and low classes according to a preset threshold value, and normal operation industrial parameter references corresponding to the working conditions are constructed; comparing the historical fault information with a normal industrial standard, generating an abnormal starting feature sequence and an abnormal ending feature sequence, and constructing a first industrial operation and maintenance reference
library and a second industrial operation and maintenance reference
library; collecting real-time industrial parameters, calling the reference
library to calculate a
score when the industrial parameters are abnormal, and generating a
troubleshooting guide; the
system comprises a historical industrial
information processing module, a normal industrial standard construction module, an operation and maintenance reference library construction module and a real-time fault
processing module which are electrically connected. The method improves the reference accuracy, achieves the quick positioning of a fault, improves the maintenance efficiency, and reduces the shutdown influence of equipment.
