System and method for monitoring vibration of cigarette maker group

Abstract

The invention provides a system for monitoring the vibration of a cigarette maker group, and the system comprises a measurement end and a fault analysis end. The measurement end comprises a controller, a vibration sensor disposed on the cigarette maker group, and a vibration feature extractor which is connected with the vibration sensor. The vibration sensor is used for collecting a vibration signal of the cigarette maker group at a preset position under the control of the controller in a preset mode. The vibration feature extractor is used for extracting a vibration characteristic quantity ofthe vibration signal under the control of the controller in the preset mode. The fault analysis end is used for obtaining a corresponding cigarette maker state through analysis according to the vibration characteristic quantity. Compared with the prior art that an original vibration signal needs to be transmitted to a fault analysis end, the system can reduce the information transmission quantityof a communication line. The invention provides a method for monitoring the vibration of the cigarette maker group, and the method is used for the above system. The method also has the above beneficial effects which are not described in details.

Description

technical field [0001] The invention relates to the technical field of cigarette machinery, in particular to a vibration monitoring system and method for a cigarette machine set. Background technique [0002] Cigarette unit is an automatic mechanical equipment for producing cigarettes, which consists of three parts: feeding machine (VE), rolling machine (SE) and filter tipping machine (MAX). Cigarette sets are used for a long time, and the general life span is about 15 years. Long-term operation will cause some components to age or even fail, affecting their normal functions. Therefore, it is more and more becoming a trend to carry out vibration monitoring on its key parts to evaluate its health status. [0003] At present, there is no recognized and systematic standard mode. The common idea of ​​the vibration monitoring system of the cigarette machine set is to use the sensor connected by wire to collect the vibration information of the key components, and then transmit th...

AI Technical Summary

Problems solved by technology

[0004] The above common ideas have the following problems: first, some components have a tight structure, and wired sensors are inconvenient or impossible to arrange; second, due to the large number of sensors arranged, the difficulty of wiring the fuselage is increased; Third, the collected vibration signal data is huge, and the transmission of the original vibration signal seriously increases the burden on the bus; fourth, the analysis results are not clear, requiring engineers and technicians to have more vibration diagnosis knowledge
