Embodiment Construction

[0048] The following describes in detail the routines of the embodiments of the present invention (such as figure 1), this example routine is implemented on the premise of the technical solution of the present invention, and provides a detailed implementation manner and a specific operation process, but the protection scope of the present invention is not limited to the following example routines.

[0049] The implementation routine can be mainly divided into the following steps:

[0050] Step 1: Apply the S-I-P-O-C-F model (eg figure 2 ) to formulate key performance indicators of equipment production activities and build an analysis model for key indicators of performance evaluation.

[0051] There are four key dimensions of equipment comprehensive performance:

[0052] 1. Quality level. The core of equipment performance evaluation is the product quality produced by the equipment. For key quality parameters, quantitatively evaluate the internal and external quality of pr...

Abstract

The invention discloses a calculation method for a performance interval of a production device, and relates to the research of an evaluation method for calculating the performance interval of the device according to interval and running real-time monitoring data. Compared with a conventional clustering algorithm, the method has the advantages that a clustering result is more accurate and the precision is higher; the influence of indexes in actual production on device performance is considered, and a weight of the index with relatively high influence is highlighted, so that a final performanceclustering center better meets an actual running condition of the device; by defining a maximum clustering radius on a mathematic level, differing from fuzzy division of other types, accurate performance interval division is obtained; the size of a collection window on the specific mathematic level is defined, and only when data in the collection window is all divided in a same interval, device performance status evaluation can be obtained, so that the evaluation accuracy is defined, and the influence of individual interference data on an evaluation result is avoided.

Description

technical field [0001] The invention relates to an evaluation method for modeling equipment performance interval division based on historical data of equipment operation, and calculating and judging the performance interval condition of the equipment according to the interval and real-time operation monitoring data. Background technique [0002] With the development of industrial technology and the expansion of the scale of manufacturing enterprises, manufacturing technology has gradually developed from semi-manual and semi-mechanized to a fully mechanized and intelligent direction. Highly complex and expensive equipment is more and more widely used in enterprise production lines. superior. The operation of the manufacturing equipment of "flow production type" enterprises has the characteristics of high safety requirements and continuous production. Once the equipment performance declines or fails, it will not only increase the maintenance cost of the enterprise, but also ha...
