Online device health status self-inspection method and system for tobacco processing equipment

Abstract

The invention discloses a method and system for self-inspection of online equipment health status of tobacco processing equipment. State parameters; construct an evaluation model of the health state of tobacco processing equipment according to the selected state parameters of tobacco processing equipment; determine the parameter weight, model parameter center value, model parameter threshold, and stage key parameters in the evaluation model of tobacco processing equipment health state; The stage of the processing equipment brings the current value of the corresponding tobacco processing equipment parameters, parameter center value, parameter threshold, parameter weight and key parameter value into the evaluation model of the health status of the tobacco processing equipment constructed, and obtains the tobacco processing equipment in the current state. Device health status. The data adopted in the present invention are real-time online data, and the above-mentioned data are more real as evaluation basis, and the quantitative evaluation is more accurate.

Description

technical field [0001] The invention relates to the technical field of tobacco processing equipment state health self-inspection, in particular to a method for self-inspection of the equipment health state of tobacco leaf feeder equipment. Background technique [0002] At present, in cigarette manufacturing enterprises, there is generally a lack of evaluation of the health status of tobacco processing equipment. Tobacco processing equipment mostly uses PLC for automatic control. The equipment alarm function is provided in the general control program, which can provide alarm prompts when some parameters of the equipment are abnormal. However, this method covers fewer equipment parameters, and only provides an alarm mechanism for a few key parameters, and the correlation between parameters is not taken into account, so the status of this equipment cannot be evaluated. At the same time, this method only considers the parameters of equipment components, and does not include th...

Problems solved by technology

[0003] In the prior art, a small number of tobacco companies have established the health status evaluation of the tobacco leaf feeder, but the evaluation method is generally a qualitative evaluation in the form of manual scoring, and there is a lack of quantitative analysis of the equipment

The evaluation granularity of this method is relatively coarse, and the subjective influence of the evaluator is relatively large

At the same time, the evaluation method is generally the comprehensive result of the overall evaluation, lacking the positioning and treatment of equipment problems

[0004] In addition, most of the existing methods for evaluating the health status of tobacco leaf feeder equipment are off-line evaluation methods

It is not possible to make an evaluation online through real-time data

Due to the long evaluation cycle and offline data distortion, the evaluation result lags behind in this method, and it cannot accurately reflect the real-time status of the current equipment.
