| Abstract: The informatization of weaving workshops relies on data collection, but this process often leads to the generation of dirty data. In order to ensure accurate data collection, this paper proposes to study data collection and cleaning algorithms for weaving workshops. Firstly, considering the diverse equipment and high data concurrency, a split-frequency acquisition scheme and a server load balancing scheme are designed, as well as a directional network for data flow processing of weaving equipment. Secondly, based on the characteristics of weaving workshop data, the data is categorized into constant components, incremental components, and status components, and the three-component cleaning algorithm is studied by combining with box plots and sliding time window to clean each component data. Finally, experimental results demonstrate that the collection scheme and data cleaning method can ensure the real-time,effective, and accurate data collection. |
