Objective To design a quality traceability system for the whole process of tobacco production based on multi-block MICA-PCA (modified independent component analysis-principal component analysis) principal component feature detection. Methods The structure model of quality traceability system in the whole process of tobacco production was constructed and analyzed, and the information of source data in the process of quality traceability was extracted and dispatched. The system design of quality traceability source in the whole process of tobacco production was realized by using multi-block MICA-PCA method to fuse the dispatching information. Results The positioning ability of the system for the whole process of tobacco production quality traceability was better, the data transmission efficiency was higher, the quality traceability performance of the whole process of tobacco production was stronger. Conclusion This quality traceability source system can improve the real-time and accuracy of quality traceability in the whole process of tobacco production.
