A system and method for condition monitoring and intelligent operation and maintenance of a subway axial flow fan

Abstract

The invention discloses a state monitoring and intelligent operation and maintenance system and method of an axial flow fan in a subway, which realizes the aerodynamic state monitoring of the axial flow fan, automatic early warning of failure of mechanical and electrical components and closed-loop operation and maintenance on the line, and can align the line according to the operation and maintenance data Optimizing and adjusting the closed-loop scheme of online operation and maintenance. The system includes: the data acquisition device obtains the working conditions of the axial flow fan and the sensor data for feature extraction and data screening, and sends the feature data and the screened raw data to the full data warehouse of the subway company; Relevant data and maintenance suggestions are sent to the operation and maintenance terminal; relevant data and maintenance suggestions for the diagnosis conclusion of the operation and maintenance terminal are used for operation and maintenance of axial flow fans; the operation and maintenance process and results and the background algorithm software of the full data warehouse realize data interaction and correct the diagnosis configuration parameters and Maintenance suggestion information base to improve the accuracy of diagnosis, and the maintenance suggestions given are more suitable for the user's personality habits.

Description

technical field [0001] The invention relates to the field of rail transit, in particular to a state monitoring and intelligent operation and maintenance system and method for a subway axial flow fan. Background technique [0002] With the rapid development of domestic urban rail transit and the accelerated pace of subway construction, the functions of fire evacuation, air supply, and smoke exhaust in the underground tunnel space have attracted more and more attention. The health status of special tools is directly related to the safe operation of the subway. [0003] Axial flow fans are scattered in various underground stations. In order to ensure the normal operation of axial flow fans, maintenance management modes such as daily maintenance, planned maintenance, and overall regular replacement are mainly adopted at present. [0004] However, the use of maintenance management modes such as daily maintenance, planned maintenance, and overall regular replacement requires a la...
