Problems solved by technology

[0005] The traditional quality traceability method is inefficient and cannot meet the business analysis and processing needs of current enterprises. At present, the quality traceability of most circuit breaker products is only a simple solution to the quality problems that arise in the current single process link. The traceability method is simple and traceable The depth is not enough and the traceability range is single, so the accuracy of the traceability results is poor, and the full life cycle data of the circuit breaker is not used, resulting in a waste of analysis resources

Embodiment 1

[0030]During the circuit breaker assembly and production process, it is necessary to carry out factory tests on the products in the mechanical characteristic test link, automatic running-in test link and power frequency withstand voltage test link, and trace the root cause of the assembly quality problem of unqualified products and adjust them until they are qualified. The traditional traceability method is that the inspectors compare the differences according to the test data and inspection standards, determine the category of quality problems, and make trial-and-error adjustments based on experience and knowledge. This method is one-sided, subjective, blind, and inefficient, and directly affects the product. quality and production progress.

[0031] Aiming at this current situation and problem, the present invention has carried out research and proposed a circuit breaker assembly quality problem traceability system based on big data analysis. This system is based on the secon...

Embodiment 2

[0034] The overall composition of the circuit breaker assembly quality problem traceability system based on big data analysis is the same as that in Embodiment 1, see figure 1 , the data storage module in the present invention is to store the data required for training the classification model and the traceability model in the Hive database module of the Spark platform, and the data storage scope covers the necessary data in the whole life cycle process of the circuit breaker, from parts and components into From the field to the final assembly to complete the factory use, including test data, process data and report data.

Embodiment 3

[0036] The overall composition of the circuit breaker assembly quality problem traceability system based on big data analysis is the same as that in Embodiment 1-2, see figure 1 , the data preprocessing module of the present invention includes a cleaning processing submodule, a normalization processing submodule, a dimensionality reduction processing submodule and a discretization processing submodule. The cleaning processing sub-module is to detect and fill the null values ​​in the original data, so as to avoid abnormalities caused by missing data when building the model. The normalization processing sub-module is to map the data processed by the cleaning processing sub-module to the [0,1] interval, to eliminate the dimensional influence caused by the inconsistency of data units between different features, so that all data are in the same reference system. The dimension reduction processing sub-module is to map the high-dimensional features processed by the cleaning processin...

Abstract

The invention discloses a circuit breaker assembly quality problem tracing system and method based on large data analysis. The problem that an ancillary system cannot meet the requirement of massive data analysis in a circuit breaker assembly production process is solved. The new idea of quality circuit breaker assembly quality problem tracing is provided from the aspect of data mining. The method comprises the steps that Spark is used to build a large data analysis platform; data preprocessing is carried out in combination with business; K-Means is used to build an assembly quality problem classification model based on distance; an Apriori association rule algorithm is used to build an influential factor analysis model; and assembly quality problem tracing is realized. The assembly quality problem classification model completes the deficiencies of mechanism classification or experience classification from the aspect of data characteristics. According to the invention, the system and method are capable of storing and analyzing massive data, have the advantages of high-performance redundancy, real-time and efficient data analysis and storage, are used for circuit breaker assembly quality problem tracing, and provide suggestions and references for circuit breaker assembly quality production.

Description
