Customized woodworking furniture flexible production line fault diagnosis system

Abstract

The invention discloses a customized woodworking furniture flexible production line fault diagnosis system. The system comprises a data layer, a diagnosis layer and a visualization layer. The data layer is used for collecting operation state data of key processing equipment on the customized woodworking furniture flexible production line, compressing the collected data based on an improved data compression algorithm, and reducing redundancy when the data is uploaded to the cloud server; the diagnosis layer is used for carrying out preprocessing and feature extraction on the collected signals, and based on an integrated learning strategy, adopting an improved particle swarm optimization algorithm to optimize a fault diagnosis algorithm of a probabilistic neural network to diagnose the type of a fault occurring in the customized woodworking furniture flexible production line; and the visualization layer is used for monitoring the operation state of the customized woodworking furniture flexible production line in real time, displaying a diagnosed fault result, querying historical fault information and pushing maintenance information. The system can quickly diagnose equipment faults, reduce the downtime caused by the fact that the production line is not checked in time, and improve the processing efficiency of the production line.

Description

technical field [0001] The invention belongs to the field of fault diagnosis of manufacturing production lines, in particular to a fault diagnosis system for a flexible production line of customized woodworking furniture. Background technique [0002] With the rapid development of my country's real estate industry and the rapid advancement of urbanization, the demand for the output and quality of woodworking furniture, especially wooden doors, is also increasing. The production level of wooden door manufacturers is getting higher and higher, and the scale is getting bigger and bigger. Since my country's wooden door manufacturing is dominated by customized production, with the improvement of the manufacturing industry and the attenuation of labor dividends, the wooden door production line has begun to develop towards flexibility, intelligence, and modularization. At the same time, the failure of the wooden door production line is becoming more and more complicated. If the wo...

Problems solved by technology

[0003] At present, for the flexible production line of customized woodworking furniture, domestic manufacturers still focus on the processing functions and processing beats of the processing machine tools on the production line, and do not pay enough attention to the fault diagnosis system. Usually, the user has a problem when using the production line to produce wooden doors and requests the production line The manufacturer sends technical experts to conduct on-site inspections. During this period, the production line often needs to be shut down, which affects the production progress of the user's wooden door and consumes a lot of time, manpower and material resources.
