Abstract

The invention provides a visual inquiry system and a visual inquiry method of a production index change trend based on similarity, which relates to the technical field of visual analysis of an execution manufacturing system. The system includes an index management module, index data cleaning module, index query module and index visualization module, which realizes the management and visual query of industrial production indicators. Operators select the time series to be queried, match the characteristics with the historical data, extract similar time series data, and visualize them to assist users to insight into the relationship between the historical data of industrial production indicators, and ultimately achieve the purpose of assisting decision-making. The visual inquiry system and method of a production index change trend based on similarity of the invention can find out index data similar to the time series from historical data, display it to operators, help operators to carry out visual analysis for each production index, insight into the relationship between the data, and assist decision-making.

Description

technical field [0001] The invention relates to the technical field of visual analysis of executive manufacturing systems, in particular to a similarity-based visual query system and method for production index change trends. Background technique [0002] The industrial production process generally has the characteristics of long process, many procedures and many equipments, and the process configuration in the mineral processing production process is flexible and changeable. In the production process, in order to improve the production quality and benefit more efficiently, it is necessary to analyze the indicators in the production process. During the indicator analysis process, the historical data of the indicators that have similar characteristics to the indicators to be queried are of great importance to the analysis indicators. Characteristics play an important role, so extracting historical data of indicators with similar characteristics for comparative analysis is of ...
