针对熔模铸造企业车间设备种类多,数据传输协议和存储结构不统一,异构数据采集困难、采集的数据杂乱缺失等问题,提出一种车间生产和设备资源的数据采集与管理框架.基于车间多源异构数据感知处理策略,设计车间数据传输路线,解决设备间数据交互差、感知处理困难的特点.结合主成分分析(PCA)和长短期神经网络(LSTM)算法,建立车间生产变化规律预测模型,完成车间数据处理和分析预测.最终,利用车间数据采集与管理框架,实现了 28项工艺及现场数据的采集,且最小采集间隔时间可达 1 000 ms,单日采集数据可达 5×105 条.建立车间铸件产量预测模型,平均绝对误差为 0.046 2%,决定系数为 0.915 2,模型具有良好的泛化性.
Data Acquisition and Production Intelligent Prediction in Casting Workshop
In view of problems of equipment in the workshop of investment casting enterprises,heterogeneous data transmission protocol and storage structure,difficulty,disorder and missing in heterogeneous data collection,a data acquisition and management framework for workshop production and equipment resources was proposed.Based on per-ception processing strategy of multi-source heterogeneous data in the workshop,the data transmission route was designed,and the characteristics of poor data interaction between devices and difficulty in perception processing were solved.Combined with principal component analysis(PCA)and long short term neural network(LSTM)algorithm,a prediction model for variation law of workshop production was established,and processing as well as analysis predic-tion of data were completed.Finally,the workshop data acquisition and management framework were utilized to achieve acquisition of 28 processes and site data,where the minimum acquisition interval can reach 1 000 ms,and 5×105 data can be collected per day.The prediction model of casting production was built,with the average absolute error of 0.046 2%and determination coefficient of 0.915 2,indicating desirable generalization.
